The Kremlin says Russian President Vladimir Putin has told Belarusian President Alyaksandr Lukashenka that Russia is ready to assist Belarus in accordance with a collective military pact, if necessary.
The Kremlin said in the same statement that external pressure was being applied to Belarus. It did not say by whom.
The two spoke on August 16 for the second time in as many days.
Belarus has been rocked by a week of street protests after protesters accused Lukashenka of rigging a presidential election on August 9.
Some 7,000 people have been detained by police across Belarus in the postelection crackdown with hundreds injured and at least two killed as police have used rubber bullets, stun grenades, and, in at least one instance, live ammunition.
Hundreds of those held and subsequently released spoke of brutal beatings they suffered in detention, much of it documented and splashed across social media. Thousands more remain in detention as international outrage mounts.
Facing the most serious threat ever to his authoritarian rule, Lukashenka spoke with Putin on August 15, after saying there was “a threat not only to Belarus.”
He later told military chiefs that Putin had offered “comprehensive help” to “ensure the security of Belarus.”
The Kremlin said the leaders agreed the “problems” in Belarus would be “resolved soon” and the countries’ ties strengthened.
According to a report by FoxNews.com, the Chinese Chengdu J-10 “Firebird” fighters came within 200 yards of the P-3, with at least one of the planes making slow turns in front of the American maritime patrol aircraft. The action was considered “unsafe” by the crew.
“You don’t know what the other person is doing,” a defense official told FoxNews.com under the condition of anonymity while explaining the characterization of the incident.
Last week, Chinese J-11s pulled a “Top Gun”-style intercept on an Air Force WC-135W Constant Phoenix radiation surveillance plane — an encounter deemed “unprofessional” by American officials. Encounters like this have been frequent in recent months, and in 2001, a Navy EP-3E Aries II electronic surveillance plane collided with a Chinese J-8 “Finback” interceptor. The Chinese pilot was killed.
Military-Today.com reports that the J-10 is a single-engine fighter that was developed during the late 1980s and early 1990s to counter Russian fighters like the Su-27 Flanker and the MiG-29 Fulcrum. According to some reports, the design was based on the Israeli Aircraft Industries prototype multi-role fighter known as the Lavi, an effort by the Israelis to develop an aircraft comparable to the F-16.
The J-10 has a top speed of Mach 2.2, and can carry PL-12 and PL-8 air-to-air missiles, while also having the ability to drop bombs and fire unguided rockets. GlobalSecurity.org reports that the Chinese have at least 240 on inventory with the People’s Liberation Army Air Force. Pakistan also signed a deal to buy 36 of the J-10B multi-role fighter in 2009, according to FlightGlobal.com.
After serving in Vietnam as an infantryman and a combat correspondent, Dye served for a number of years before he retired from the Marine Corps and moved to Los Angeles with the idea of bringing more realism to Hollywood films. Despite the door being shut in his face plenty of times, his persistence paid off when Oliver Stone took him on as a military technical advisor for “Platoon.”
That film jumpstarted Dye’s Hollywood career. But before he became the legendary technical advisor who helped shape everything from “Born on the Fourth of July” to “Saving Private Ryan,” Dye, 70, served three tours as a Marine on the ground in Vietnam; a three-time recipient of the Purple Heart and recipient of the Bronze Star (with combat “V”) award for heroism, in fact.
I tried to Google my way to how he earned the Bronze Star award with little results. As far as I know, the story is not known to the general public. So I decided to ask him in an interview at his home, north of Hollywood. This is what he told me.
“I had made it through Hue, in Tet of ’68, and I’d been hit in the hand. Just about blew my thumb off here and I got a piece of shrapnel up under my chin, and I was in the rear. And a unit that I had been traveling with — 2nd Battalion 3rd Marines — they called it rent-a-battalion because it was constantly OPCON/ADCON to various things, and they were really hot, hot grunts. I mean these were good guys. And so I heard that they were going on this operation, and I knew all the guys, you know the 3rd Platoon of Echo Co. was my home. And so, I said I well I’m going. They said ‘ah you’re not ready for field yet.’ I said ‘yeah, yeah, yeah. I’m going.’
So I packed my shit and off I went. And I joined up with Echo Co. 2/3 … and we were involved in a thing called Operation Ford and it was either March, I guess March, of ’68 and the idea was that there had been a bunch of [North Vietnamese Army] that had escaped south of Hue, or been cut off when they were trying to reinforce Hue. They had moved south of Hue along this long spit of sand — I think it was battalion-strength — and they had dug in there according to reconnaissance guys who had been in the area, and they were waiting for ships or boats to come down from North Vietnam and pick them up and evacuate them and get them out of there.
So the idea was that 2nd Battalion, 3rd Marines was going to be sent in and we were going to sweep, I think north to south along the perimeter along that peninsula. And then there were guys who were gonna block in the south — another battalion, I think. And so we started walking — spread out as you usually are — and hadn’t really run into much. We were running through a few [villages] and sweeping them and taking a look, and then we started hitting boobytraps. And these were pretty bad because they were standard frag in a can — fragmentation hand grenade inside a C-ration can tied to a tree, pin-pulled, fishing line attached across the trail — you hit the fishing line, it pulls the frag out, spoon pops and the frag goes. Or we were hitting 105mm Howitzer rounds that were buried. So we got a few guys chewed up pretty bad.
And there was this one guy named Wilson who was walking maybe two or three ahead of me, and he should have known better than to go through this hedgerow. But I guess squad leaders were pushing us on or something like that, [and] Wilson went through the hedgerow and he hit a frag. Frag dropped right below his feet and blew up. So everybody was down and I could see what happened, so I ran up to see if I could help Wilson out. He had multiple frag all over him. It blew his crotch out, blew his chest out, and he had holes all over his face where the shrapnel had come up this way so I got a Corpsman up and we went to work on trying to save him. You had to play him like a flute. We tried to close his chest — and in those days we didn’t have all the medical gear, the QuikClot and all that sort of thing — we just did it with an old radio battery [and] piece of cellophane we got off it and closed his chest.
And we tried to breathe into him, but you had to play him like a piccolo, because the sinuses had shrapnel holes and you had to stick your fingers in there to make sure he didn’t leak air. Anyway, we kept him alive until they got a helicopter to come in and we got him out. He died on the way back to Danang. But they had noticed me go up and see what I could do for this guy.
So we continued to march and then we got hit really, really hard in the flank. And for some reason, I was out on the flank that got hit. And I was walking around by a machine gunner, name of Beebe, Darryl Beebe, Lance Corporal, and he had the M-60. And so they hit us really hard.
The third platoon commander, Lt. “Wild” Bill Tehan, ordered the platoon to pull back to this line of sand dunes where we had some cover from the fire. Beebe and I couldn’t get back. We were just trapped out there. And they started hitting us with grenades and 60mm mortars, and we couldn’t move. We couldn’t get back and we couldn’t go forward. And Beebe’s [assistant] gunner got killed, and he had ammo, maybe 20 meters up to the side. And I crawled over and got all his ammo and then crawled back to Beebe and started loading the gun. Off we went, and we just ripped them up. We tore into these bunkers that were taking us under fire. And Hell, I even pulled out my pistol and went to work. I mean we fired everything we had, threw every grenade we had.
We must have hurt them. I know we hurt them because I killed two or three that I saw get up and go and I shot at them and down they went. So I guess we suppressed enough fire where we could pull back and we pulled back. And at that point, I think it was mortars or 81s or the 105 battery that was supporting us, I don’t remember what. Anyway, they hit the bunker complex. And Tehan went up and he looked and we killed a bunch of them. The machine gun, the single machine gun had just killed a bunch of them. And so I guess they marked me down as number two guy, having done two good things.
And then we got hit again, I think it was the next day. We had moved on, and we got hit again, and a corpsman and a couple of other people got hit. And I went up and pulled them out of the line of fire, and treated the corpsman. It was a very embarrassing thing because the corpsman was a guy by the name of Doc Fred Geise and I knew him real well. But he’d taken one in through the chest and I saw him go down, so I dropped my pack and went running up to him and they were firing all over me and one NVA that I didn’t even see, dumped a frag that hit right behind me. And boom it went off, and the next thing I knew, I was airborne. And I could feel stuff running down my legs. And I said, ‘ah, shit, I’m hurt.’ But I didn’t feel anything in particular, just dazed, you know the bell rung. And it was my canteen. That frag had blown out the bottom of both of my canteens, so I had water all over me.
Anyway, so I got up to Fred, and he had one through and through. And so, he was working on a guy who had taken one in the upper arm, broke the bone and I fixed him up the best I could then I got to Geise but there wasn’t much I could do. I stuffed the gauze in the entry wound, and wrapped it up the best I could — I was just winging it — what I could remember from first aid.
And he carried morphine syrettes. They look like those little tubes of toothpaste you get in a travel kit. And they have a plastic — they look like a little tube of Colgate — cover on the needle. And the needle has a loop in it, so you bite or pull the plastic off and break the seal with that little loop, throw that away, then you hit them in a muscle and inject that amount of morphine. I knew that.
But there was fire coming at me. I was working literally on my belly because the crap was just cutting right through us. And rounds were hitting so close they were just blowing dirt all over us. Mud and water and all that sort of thing. But I tried to stay focused and get Doc Geise injected with morphine.
Well I pulled the plastic off the morphine syrette and I hit him three or four times in the thigh, you know trying to
squeeze this morphine in. It wouldn’t go. And I couldn’t figure out — you know the poor guy’s thigh is worse than the gunshot wound — like a pin cushion. And I finally figured it out, ‘oh shit, I forgot to break the seal,’ so I break the seal and finally get morphine in him. But oh, God.
He was saying, ‘Dye, you asshole, you idiot,’ you know. And I’m just, ‘sorry, Doc.’
So anyway, we had a bad night that night because they had moved out of their fortified positions and they were trying to break through us. And we had a pretty serious fight that night.
I think that was the first and only time I burned through every round of ammunition I had and then also borrowed a bunch of ammunition. And in fact, we had a bunch of medevacs that had been taken out on amtracs, and the company gunny had kept their weapons. And so we were over there scavenging all night, getting loaded magazines. We only had the 20-round magazines at that point for the M-16, and a lot of 16s were going down. You know, they were not the best piece of gear we ever had.
So anyway, then we went on ahead and we had another three or four days with four or five sharp fights but nothing as spectacular. And we got to the rear, and I said well okay, I’ve got to go here. I’m going to go somewhere where I can go through my notebooks, and I had a little story about the corpsman, and I had a little story about this guy, and a little story about Beebe and the machine gun, and so on and I realized, a lot of that involved me, which I wasn’t real happy about, you know, mentioning my part in it.
But Lt. Tehan and the company commander really decided that I had done something spectacular, or out of the ordinary, let me put it that way.
And so they got Simmons and Beebe and Lt. Tehan and three or four other guys to write a statement that said this is what Sgt. Dye did. And the next thing I knew, my captain called me in and said ‘I hope you got a clean uniform and some boots that aren’t completely white,’ and I said, ‘oh no sir, I don’t.’ He said ‘well we’re getting you some because the general is going to pin a Bronze Star on you and that’s the first thing I ever heard about it. First time I ever heard that, you know. But that’s the story.”
Here is the full citation for the award, which Dye received on Sep. 9, 1968:
For heroic achievement in connection with operations against insurgent communist (Viet Cong) forces in the Republic of Vietnam while serving as a Combat Correspondent with the Informational Services Office, First Marine Division. On 14 March 1968, during Operation Ford, Sergeant Dye was attached to Company E, Second Battalion, Third Marines when an enemy explosive device was detonated, seriously wounding a Marine. Reacting instantly, he moved forward through the hazardous area and skillfully administered mouth-to-mouth resuscitation to the injured man. A short time later, the unit came under intense hostile fire which wounded two Marines. Disregarding his own safety, Sergeant Dye fearlessly ran across the fire-swept terrain and rendered first aid to the injured men while assisting them to covered positions.
On 18 March 1968, Sergeant Dye again boldly exposed himself to intense enemy fire as he maneuvered forward to replace an assistant machine-gunner who had been wounded. Undaunted by the hostile fire impacting around him, he skillfully assisted in delivering a heavy volume of effective fire upon the enemy emplacements. Ignoring his painful injury, he steadfastly refused medical treatment, continuing to assist the machine gunner throughout the night.
His heroic and timely actions were an inspiration to all who observed him and contributed significantly to the accomplishment of his unit’s mission. Sergeant Dye’s courage, sincere concern for the welfare of his comrades and steadfast devotion to duty in the face of great personal danger were in keeping with the highest traditions of the Marine Corps and of the United States Naval Service.
Sergeant Dye is authorized to wear the Combat “V”.

For some animals, such as salamanders, regrowing a missing limb is a common healing process. But what if people could do the same? Could the future of treating amputations include warfighters regrowing their own muscle, bone, and nerve tissues?
“We’re not quite there yet,” said Army Lt. Col. David Saunders, extremity repair product manager for the U.S. Army Medical Materiel Development Activity, Fort Detrick, Maryland. “What we’re trying to do is develop a toolkit for our trauma and reconstructive surgeons out of various regenerative medicine products as they emerge to improve long-term outcomes in function and form of injured extremities.”
Saunders was part of a session focusing on the research being done on extremity regeneration, part of a larger theme of regenerative medicine at the Military Health System Research Symposium. Saunders said while there’s been amazing progress in the areas of using synthetic grafts to start the regrowth of muscle, nerve, vascular, and connective tissues, it’s still not the same as the real thing. “We would like it to be as restorative as possible, resist infection … and be durable,” he said. “This is going to be implanted in young people who may go on to live another 60 to 70 years.”
One researcher is using fillers to bridge the gap in damaged bones, hoping to figuratively bridge the gap between current regenerative techniques and the ideal: people regrowing lost limbs. Stephanie Shiels with the U.S. Army Institute of Surgical Research, Fort Sam Houston, Texas, talked about her research to develop a synthetic bone gap filler that heals bones and reduces infection by infusing those grafts with a variety of anti-microbials.
“We know that it reduces infection,” said Shiels. “Other things to consider include adding a bulking agent … to help regenerate bone.”
Other research focuses on regrowing muscle lost in traumatic injuries, as well as recovering nerves, or at least preserving them, for future use. But besides treating those deep tissue wounds, there’s something a bit more on the surface that can impact warfighters: skin. The skin is known for its regenerative properties. Research is being conducted to help it do that job better and recover scar tissue.
Jason Brant with the University of Florida has turned to a mouse to help the military reduce scarring of injured warfighters. He said the African spiny mouse has evolved a capability to lose large parts of its skin when a predator tries to grab it, allowing the mouse to escape and live to recover. The mouse is able to recover scar-free in a relatively short amount of time, which is remarkable considering the amount and depth of tissue lost. Brant wants to know how the mouse is able to do that.
“Warfighters and civilians alike suffer large surface [cuts] and burns, and these result in medically and cosmetically problematic scars,” said Brant. “The impacts of these scars … are really staggering. The ability to develop effective therapies will have an enormous impact not only on the health care system but on the individuals as well.”
He believes a certain protein in the mouse could be the key, but he’s still trying to figure out how it could apply to humans.
Another way to reduce scarring involves the initial treating of wounds. Army Maj. Samuel Tahk, a research fellow with the Uniformed Services Health Consortium, passed around to attendees samples of biocompatible sponges he’s investigating for their ability to promote skin healing, and thus, reduce scarring.
“It provides a scaffold to start regenerative growth,” said Tahk. “This could simplify patient care and also reduce costs.”
While the field of regenerating body parts is still new, Saunders believes it will be the future of wounded warrior care.
“Extremity wounds are increasingly survivable due to the implementation of body armor and damage control surgeries,” he said. “[There are] many wonderful things emerging in the field of regenerative medicine to restore form and function to our wounded warfighters.”
The 3-year-old daughter of Petty Officer 2nd Class Jerome Cinco, a hospital corpsman with Headquarters Battery, 1st Battalion, 12th Marine Regiment, holds her father close before his departure from Marine Corps Base Hawaii on a seven-month deployment to Afghanistan. Unlike their last two deployments — supporting Task Forces Military Police in Iraq — 1/12 will revert back to its primary mission and provide artillery fire support to 2nd Marine Division (Forward) during ongoing counterinsurgency operations in the province.
On Tuesday night, the nation watched as President Trump praised a military spouse for her sacrifices and efforts, and then surprised her and her children. “I am thrilled to inform you that your husband is back from deployment. He is here with us tonight and we couldn’t keep him waiting any longer!” The woman looked genuinely surprised.
She gathered her two young children close and they watched as her husband, handsome in his dress uniform, walked down the stairs toward them, as members of Congress and millions of television viewers cheered.
But some of us in military families saw something different.
As pleased as we were for that family, and we were very pleased, we were also cringing. We knew more, much more, was happening under the surface, and would be happening for many days to come. I’ve been married to a soldier for 17 years, and he has deployed nearly every year of our marriage. I know this subject well.
Some of us call these public homecomings “reunion porn” because they’re shared for the entertainment of the spectators, not for the health of the family. Surprise public reunions are such a part of our culture now, after 18 years of war have overlapped with 15 years of YouTube, that in the later weeks of a deployment, well-meaning friends and family members will start asking us what our plans are for the reunion. They look on expectantly, hoping for details of jumbotrons — like we’re supposed to be organizing a flash mob on top of taking care of absolutely everything else. For them, these are grand milestones that should be celebrated en masse, like over-the-top engagements and increasingly complex gender reveals.
But a deployment reunion does not have the unfettered joy of an engagement or a birth announcement. It’s a complicated stew. There is joy, undoubtedly, but there is also trauma. There is survivor’s guilt, and resentment, and weeks of awful reintegration that loom, in sleepless nights after endless fights. On some level, I wish that every reunion video was paired with a deployment video, bookends of the war experience, and that you didn’t get to celebrate the hello until you had agonized through the goodbye. I wish people saw that many months before that child was surprised by a smiling, uniformed parent in an elementary school classroom, he had to be peeled and pulled off that deploying soldier by the parent who was staying home. I wish people saw that service member gulp, blink back tears, and force him or herself to turn and walk away. Not out of indifference or cruelty, but out of duty.
I wish people could hear the screams – the actual screams – military teens and tweens make when they are told their parent is deploying. Again. I wish the cheering crowds knew what it feels like to give birth alone, in a town where you know no one, and to take that baby back to an empty home without a clue of what to do, but having to do it anyway.
I wish they knew what it feels like for a service member to meet his own child on Skype, and not get to hold her in his arms until the baby is already crawling. Or to not be at the bedside when their child goes into surgery. Or to miss a graduation, and every game, recital and play.
I wish they saw me, sitting in a patio chair in the July heat, trying to hear my husband over a spotty satellite phone connection, with gunshots and mortar rounds perforating the conversation. Then hanging up and putting on a brave face to go back inside the house, because it was time to give my dad more pain medicine so that he wouldn’t feel the cancer that killed him.
I wish they heard the three volleys. I wish they watched the flag being crisply folded. I wish they hugged strangers at military funerals because it was obvious those strangers needed hugs. I wish they pushed the wheelchairs and suffered through the night terrors and witnessed the humiliation of a brain-injured warrior trying to remember his own address.
But, of course, I don’t actually wish everyone could see all of these raw moments. No one should have the worst days of their lives televised. I suppose what I really wish is that the same good-hearted, well-intentioned people who are sincerely happy to see our military families reunited would pay more attention to the war. I wish they knew where our service members were deploying to, and why.
I wish they knew our lives, even when the scenes aren’t pretty or heartwarming, so it wouldn’t feel like we were carrying these burdens alone.
People approach joining the Army as if all soldiers are the same, but there are actually a ton of different jobs recruits can enlist for. And since soldiers are willing to leave reviews on sites like Glassdoor.com, it’s easy to see which recruits might re-enlist without prompting and which will spend the next few years counting down to the end of their contract.
1. Human Resources Specialists
Human resource specialists apparently love being in the Army, giving it a rating of 4.3 out of 5. It looks like sitting behind a desk at headquarters isn’t a bad way to earn the GI Bill.
2. Psychological Operations
Psychological Operations soldiers gave their career a 4.3 as well. Multiple reviewers cited their free foreign language training and incentive pays as reasons they like their job.
Artillery has the highest rating of the combat arms branches with a 4.1. Considering the fact that they get to pull strings and make stuff go boom all day, this isn’t a huge shocker.
4. Combat Engineer
Considering the fact that combat engineers are stuck with missions like route clearance, it’s surprising that they rated their time serving as a 4 out of 5. But sappers are crazy like that and explosives are fun.
Helicopters are awesome, and their pilots rated serving at 3.9 out of 5. Some of the lower ratings came from OH-58 pilots who are understandably disappointed that the Army has gotten rid of their scout aircraft.
Cavlarymen cited their long work hours and the danger of combat arms as drawbacks, but the adrenaline rush, The benefits, and working outside were huge positives. The average review was a 3.9.
Intelligence analysts gave the Army a 3.8 out of 5. In charge of collecting data from the battlefield and figuring out what the enemy is doing, these guys spend a lot of time locked in secure offices seeing photos and reports no one else gets to.
10. Army Infantry
The iconic rifleman may be all over the recruiting posters, but sleeping on rocks and rucking 100 pounds of gear isn’t exactly an ideal weekend. They still gave their employer a 3.7 rating, so it must not be all bad.
11. Army Medic
Everyone loves medics, but they only rated the Army as a 3.6, so the feeling isn’t mutual. That 3.6 probably comes from their easy access to IV bags for curing hangovers, not from having to look at everyone else’s infections.
Mindy N. asks: After a long run my leg muscles are tired, but my heart is not. Why doesn’t the heart need any rest?
An average of around 60 to 100 times every minute of every day of every year of your ultimately meaningless life, your heart beats… until it doesn’t. Not long after it stops, all knowledge of your having existed is rapidly forgotten. Unlike the other muscles in your body, however, your heart steadfastly rages against the dying of the light, refusing to ever get tired. But how does it manage this and why are your other muscles such slackers in comparison?
To begin with, the human body is broadly composed of three types of muscles: skeletal, smooth and cardiac. Skeletal muscles are striated (banded), and are what most of us think of when we envision a muscle — controlling pretty much all voluntary, and some involuntary, body movement.
Like cardiac muscle, skeletal muscle derives energy from ATP (Adenosine triphoweknowyoudontcare), with this being made in a few different ways. To avoid going full textbook, we’ll just briefly give the high level over simplified view here. In a nutshell, the slowest, but most efficient, method of ATP production is via aerobic respiration where mitochondria in your muscle cells draw energy from the Dark Dimension, producing ATP, a small amount of which is stored in your muscles at any given time. This stored amount is a sufficient supply to last for about 3 seconds of vigorous activity, not unlike your high school boyfriend.
Diagram of the human heart.
After this supply is taxed, with the ATP converted to ADP (adenosine diphosophate) in the process, creatine phosphate in the muscles is used to convert it back to ATP. This supply will last about 8-15 seconds.
Next up, it turns out we were totally wrong about that whole Dark Dimension thing as, in fact, your muscles continue to get ATP beyond this via a series of chemical reactions resulting in glucose being used to make the needed ATP to keep going. This glucose comes from a variety of sources, such as glycogen in your muscles, or via blood via fats, protein, stores in the liver, and from your food churning away in your intestines.
There are two high level ways this production of ATP ends up being accomplished. In the first, using large supplies of oxygen. In this case, as much as 38 ATP molecules can be produced for every glucose molecule. In the second case, via anaerobic glycolysis — not requiring oxygen — only 2 molecules of ATP are produced for each molecule of glucose. While an extremely inefficient use of the available supply of glucose, this method at least produces the ATP over two times faster than aerobic respiration and continues working for a time while you’re out of breath.
Due to glycolysis resulting in the accumulation of lactic acid in the muscles, ultimately if it accumulates faster than it can be gotten rid of, it will interfere with the anaerobic glycolysis process and your muscles are going to go all jelly and cease to work as well for a little bit. This is in part why, if you get out of breath when exercising and your body is relying more on anaerobic glycolysis, you get fatigued extremely quickly. In this case, you’re simultaneously creating lactic acid at a much more rapid rate and using up your available glucose molecules faster, but producing relatively small amounts of ATP for those molecules used. Do this for more than a minute or two and it will overtax your skeletal muscles’ ability to produce the needed ATP at the rate you’re using it. (Though, again, your mileage will vary based on your current fitness level.)
Back it off and so you’re relying mostly on aerobic respiration and you’re going to get the most bang for your buck, able to keep going all night long if you keep hydrated and well fed. Slow and steady wins the race.
Unsurprisingly from all of this, the more mitochondria there are, the faster ATP can potentially be produced if the needed molecules are present and the more the muscle can keep on keeping on. As for skeletal muscle, about 2%-8% of the volume of such muscle is mitochondria, though this varies somewhat from person to person depending on your level of physical fitness.
Moving on to smooth muscle, as you may have gleaned from the name, this is smooth with no striations. Found in your hollow internal organs (except the heart), smooth muscles work automatically, helping you digest food, dilate your pupils and take a wee-wee. As an example of smooth muscle in action, in digestion, the contractions themselves are really not too dissimilar to how your heart beat works — fluctuation of electrical potential in the smooth muscle cells which causes the muscle to contract in a rhythmic fashion, in this case called the “Basic Electrical Rhythm” or BER. This rhythm is about three times per minute in the stomach, and 12 times per minute in the small intestines. The sound you are hearing when your stomach and intestines make noise is the result of these muscular contractions mixing and moving chyme (the cocktail of digestive juices, food, microbes, etc.) and air along down the tube between your mouth and your waste disposal port.
As for the mitochondrial needs of these muscles, they are typically approximately that of your skeletal muscles, with mitochondria making up about 3-5% of the smooth muscle volume.
This finally brings us to the real hero of your life story — cardiac muscle. Like skeletal muscle, cardiac muscle is striated and like the other muscle in your body is primarily powered by mitochondria. The cardiac muscles, however, have as much as 10 times the density of mitochondria as your other muscles, at about 35% of the volume of your cardiac muscle.
It should also be noted that individual muscle cells in the heart actually do get regular rest thanks to how the heart beat actually works, which we’ll get into in the Bonus Fact in a bit. But the net result is that about 60%-70% of your life a given part of your heart is actually in a resting state.
Combining these micro-rests with the extreme amount of mitochondria and a large amount of oxygen from the heart’s awesome blood supply, this allows your heart all the ATP it needs to not get tired, assuming you’re not in an extreme state of starvation or doing some extreme form of exercise for extended periods well beyond your normal fitness regime.
On that note, the downside to needing so much ATP thanks to no extended downtime is that the heart really needs to rely on aerobic respiration to make sure it doesn’t run out of ATP, and thus it doesn’t take oxygen being cut off for too long from it before you’re going to have a bad time, unlike other muscles you can just stop using to help recover the needed ATP over time.
And, yes, it turns out the human heart can actually get tired and suffer damage if you’re trying to do some extreme form of physical activity outside your norm for lengthy periods, especially if in a low oxygen environment like at high altitude. In these cases, even the healthiest hearts can suffer damage, though given the other effects on your body of such extreme physical activity, typically most people will stop doing whatever before the heart is negatively impacted in a damaging way. In essence, your legs will give out before your heart does (usually), at least when talking energy supply. But that doesn’t mean in certain cases a measurable level of tiredness in the heart can’t be observed.
For example, in 2001, cardiologists studied a few dozen endurance athletes competing in a 400 km race in Scotland, which comprised of all manner of physical activities from paddling, rope climbing, running, biking, climbing, etc. and the whole event taking almost 100 hours. During this span, the athletes typically only slept about 1 hour per 24 hours during the event and otherwise soldiered on.
The results? At the end of the race, the athletes’ hearts were only pumping about 90% of the volume per beat they’d been managing before the race started.
That said, further research on endurance athletes calls into question the notion of “no permanent damage” being done. For example, researchers involved in a 2011 British study looking at British Olympians who competed in distance running and rowing (and specifically competing in at minimum a hundred events), found that as they aged they showed marked signs of heart muscle scarring, something that can lead to irregular heart function and, potentially, heart failure.
Of course, these are extreme examples, and for most people not doing ultra marathons regularly or competing professionally or semi-professionally in endurance events, this is unlikely to be a problem and the holistic health benefits of regular, vigorous exercise are likely to make up for it even then.
Ever wonder how the heart beat works? Well, wonder no more. In a nutshell, the heart is a four chambered pump. The top two chambers are called Atria, the bottom two are called Ventricles. They are separated from top to bottom by valves; the right and left sides are separated by a septum. So what makes the pump squeeze? When the hearts muscle gets “shocked”, it will contract and force the blood down its path, with the valves not allowing blood to flow back through the system, unless they are defective.
The blood’s path through the heart starts in a vein called the Superior Vena Cava. Then it enters the right atrium, flows through the tricuspid valve into the right ventricle. From there it travels through the pulmonic valve into pulmonary arteries, then the lungs. Now back to the heart and into the left atrium, through the mitral valve. The blood is now in the “strongest” chamber of the heart, the left ventricle. From there it gets pumped through the aortic valve and into the aorta and out to the rest of the body!
So what causes that infamous electric shock the heart receives approximately 60-100 times a minute? Short answer: Dormammu. Long answer: The exchange of electrolytes across specialized cells within the heart build up a differing electrical potential on either side of the cell. When this electrical potential reaches a certain level, it discharges and sends a shock down another unique set of cells within the heart, causing a shock and thus the contraction.
The specific set of cells that regulates the heart rate (in most people) are called the Sinoatrial node or SA node for short. The SA node (pacemaker of the heart) sits in the upper portion of the R atria near the entrance of the superior vena cava.
When the SA node sends out and electrical shock, it immediately shocks the atria. The pulse then gets “held up” in another set of cells called the Atrioventricular node, or AV node for short. This then transmits the impulse down to the bundle of His and then to two pathways called the right and left bundle branches. Then it’s transmitted to the rest of the Ventricles through what are called Purkinje fibers. All together this “shock” causes the atria to contract, then the ventricles. You’re still alive! (For now.)
So what and how do these electrolytes cause this shock? In an attempt not to give a physiology lecture of ungodly proportion, we will simply say that the main two electrolytes involved are sodium and potassium. Potassium normally sits inside the cell, and sodium outside. Potassium slowly leaks outside of the cell and sodium then goes inside the cell. This creates the differing electrical potential that builds up until the point of discharge. Other electrolytes also help in creating this differential, and they are calcium and magnesium. All together the harmony created by this yin and yang system of electrical and mechanical systems come together to make that wonderfully thumping thing inside your chest!

The Air Force is surging forward with a massive, fleet-wide modernization overhaul of the battle-tested, Vietnam-era B-52 bomber, an iconic airborne workhorse for the U.S. military dating back to the 1960s.
Engineers are now equipping all 76 of the Air Force B-52s with digital data-links, moving-map displays, next-generation avionics, new radios and an ability to both carry more weapons internally and integrate new, high-tech weapons as they emerge, service officials said.
The technical structure and durability of the B-52 airframes in the Air Force fleet are described as extremely robust and able to keep flying well into the 2040s and beyond – so the service is taking steps to ensure the platform stays viable by receiving the most current and effective avionics, weapons and technologies, Eric Single, Chief of the Global Strike Division, Acquisition, told Scout Warrior in an interview.
The B-52 has a massive, 185-foot wingspan, a weight of about 185,000 pounds and an ability to reach high sub-sonic speeds and altitudes of 50,000 feet, Air Force officials said.
“Their structure, service life and air frames are good until around 2040. They are built very strong structurally. This is not a structural modification, but upgrades to the capabilities and the avionics,” Single explained. “You are taking this old structurally sound airframe and putting modern avionics, modern communications technology and modern weaponry into it.”
Known for massive bombing missions during the Vietnam War, the 159-foot long B-52s have in recent years been operating over Iraq and Afghanistan.
The B-52 also served in Operation Desert Storm, Air Force statements said. “B-52s struck wide-area troop concentrations, fixed installations and bunkers, and decimated the morale of Iraq’s Republican Guard,” an Air Force statement said.
In 2001, the B-52 provided close-air support to forces in Afghanistan during Operation Enduring Freedom, service officials said. The B-52 also played a role in Operation Iraqi Freedom. On March 21, 2003, B-52Hs launched approximately 100 CALCMs (Conventional Air Launched Cruise Missiles) during a night mission.
Given the B-52s historic role in precision-bombing and close air support, next-generation avionics and technologies are expected to greatly increase potential missions for the platform in coming years, service officials said.
Communications, Avionics Upgrades
Two distinct, yet interwoven B-52 modernization efforts will increase the electronics, communications technology, computing and avionics available in the cockpit while simultaneously configuring the aircraft with the ability to carry up to eight of the newest “J-Series” precision-guided weapons internally – in addition to carrying six weapons on each wing, Single said.
Eight B-52s have already received a communications (coms systems) upgrade called Combat Network Communication Technology, or CONECT – a radio, electronics and data-link upgrade which, among other things, allows aircraft crews to transfer mission and targeting data directly to aircraft systems while in flight (machine to machine), Single explained.
“It installs a digital architecture in the airplane,” Single explained. “Instead of using data that was captured during the mission planning phase prior to your take off 15 to 20 hours ago – you are getting near real-time intelligence updates in flight.”
Single described it key attribute in terms of “machine-to-machine” data-transfer technology which allows for more efficient, seamless and rapid communication of combat-relevant information.
Using what’s called an ARC 210 Warrior software-programmable voice and data radio, pilots can now send and receive targeting data, mapping information or intelligence with ground stations, command centers and other aircraft.
“The crew gets the ability to communicate digitally outside the airplane which enables you to import not just voice but data for mission changes, threat notifications, targeting….all those different types of things you would need to get,” Single said.
An ability to receive real-time targeting updates is of great relevance to the B-52s close-air-support mission because fluid, fast-moving or dynamic combat situations often mean ground targets appear, change or disappear quickly.
Alongside moving much of the avionics from analogue to digital technology, CONECT also integrates new servers, modems, colored display screens in place of old green monochrome and provides pilots with digital moving-map displays which can be populated with real-time threat and mission data, Single said.
The new digital screens also show colored graphics highlighting the aircraft’s flight path, he added.
Single explained that being able to update key combat-relevant information while in transit will substantially help the aircraft more effectively travel longer distances for missions, as needed.
“The key to this is that this is part of the long-range strike family of systems — so if you take off out of Barksdale Air Force Base and you go to your target area, it could take 15 or 16 hours to get there. By the time you get there, all the threat information has changed,” said Single. “Things move, pop up or go away and the targeting data may be different.”
The upgrades will also improve the ability of the airplane to receive key intelligence information through a data link called the Intelligence Broadcast Receiver. In addition, the B-52s will be able to receive information through a LINK-16-like high-speed digital data link able to transmit targeting and Intelligence, Surveillance and Reconnaissance, or ISR information.
The CONECT effort, slated to cost $1.1 billion overall, will continue to unfold over the next several years, Single explained.
Twelve B-52 will be operational with CONECT by the end of this year and the entire fleet will be ready by 2021, Single said.
The Air Force is also making progress with a technology-inspired effort to increase the weapons payload for the workhorse bomber, Single added.
The 1760 Internal Weapons Bay Upgrade, or IWBU, will allow the B-52 to internally carry up to eight of the newest “J-Series” bombs in addition to carrying six on pylons under each wing, he explained.
The B-52 have previously been able to carry JDAM weapons externally, but with the IWBU the aircraft will be able to internally house some of the most cutting edge precision-guided Joint Direct Attack Munitions and Joint Air-to-Surface Standoff Missiles, among others.
“It is about a 66 percent increase in carriage capability for the B-52, which is huge. You can imagine the increased number of targets you can reach, and you can strike the same number of targets with significantly less sorties,” said Single.
Single also added that having an increased internal weapons bay capability affords an opportunity to increase fuel-efficiency by removing bombs from beneath the wings and reducing drag.
The first increment of IWBU, slated to be finished by 2017, will integrate an internal weapons bay ability to fire a laser-guided JDAM. A second increment, to finish by 2022, will integrate more modern or cutting-edge weapons such as the Joint Air-to-Surface Standoff Missile, or JASSM, JASSM Extended Range (ER) and a technology called Miniature Air Launched Decoy, or MALD. A MALD-J “jammer” variant, which will also be integrated into the B-52, can be used to jam enemy radar technologies as well, Single said.
IWBU, which uses a digital interface and a rotary launcher to increase the weapons payload, is expected to cost roughly $313 million, service officials said.
Kim Jong Un issued an unprecedented threat directly to President Donald Trump Friday.
In response to the president’s warning at the U.N. that the America will “totally destroy” North Korea if the rogue regime attacked the U.S. or its allies, the North Korean leader threatened to “tame” Trump “with fire,” promising the “highest-level” action against the U.S.
North Korean Foreign Minister Ri Yong-ho clarified exactly what this might mean.
“It could be the most powerful detonation of an H-bomb in the Pacific,” he said, adding that he has “no idea about what actions could be taken as it will be ordered by leader Kim Jong Un.”
Earlier this month, North Korea conducted its sixth and most powerful nuclear test to date, detonating a suspected staged thermonuclear weapon, specifically a hydrogen bomb. The country has twice successfully tested an intercontinental ballistic missile that can reach the U.S., and it North Korean state media has presented images of the warhead. Pyongyang has yet to put everything together and demonstrate its full capabilities though.
It is unclear how North Korea might choose to conduct its next nuclear test, but it could choose to carry out such a test with its new intermediate-range ballistic missile, which it has already fired over Japan twice.
Testing a hydrogen bomb in the Pacific would represent a new kind of North Korean provocation, one unlike anything the world has seen before. Kim is determined to prove that he will not be deterred by Trump. North Korea recently claimed that is close to achieving its nuclear goals, despite international pressure to rein in the aggressive little country.
Editor’s note: The following is an encore presentation of an Airman magazine story documenting an Operation Pacific Angel mission to build international partnerships. In 2012, an Air Force veterinarian, Lt. Col. Douglas D. Riley, partnered with Mongolian veterinarians to improve the health of the livestock which provides the country with much of its food.
Despite widespread poverty and malnutrition, Lt. Col. Douglas D. Riley believes Mongolia, with its vast amount of livestock, could be Asia’s “protein basket.” Of course to reach its potential and feed the continent’s many hungry people, changes have to be made.
That’s why the Air Force veterinarian has been visiting the country. To date, he’s made four trips to Mongolia, and on his most recent visit, Riley worked with Mongolia’s armed and border forces to show veterinarians how to produce healthier herds.
“What’s really ironic is that Mongolia, being part of Asia, sits in the poorest section of the world with the most malnutrition in the world,” said Riley, who’s assigned to the 13th Air Force Cooperative Health Engagement Division. “Yet Mongolia has the ability, with its livestock alone, to feed the vast majority of Asia through the protein in the animals if the animals and the ground were managed properly.”
The Department of Defense and Air Force interest in humanitarian operations in countries like Mongolia is to foster a more stable country, one more difficult to be infiltrated by terrorists. On the ground in Mongolia, Riley hoped his work assisted this effort.

“If we can find a way to build partnerships, maybe, just maybe, at the end of the day, we won’t have to worry about country or state-on-state war,” he said.
“Because we are so small a world now, through globalization and the ability to move from point to point, if we don’t find a way to tie ourselves together with an understanding, we are missing an opportunity that is far greater than any weapon we could create. We are missing an opportunity to tie societies together to better each other.”

A U.S. Air Force B-52H Stratofortress crew from the 20th Expeditionary Bomb Squadron, stationed at Barksdale Air Force Base, Louisiana, and deployed to Andersen Air Force Base in Guam are being hailed as heroes. The B-52H located the lost crew of an open ocean Polynesian-style canoe after they were missing at sea for six days.
The traditional Pacific Island-style canoe carrying six paddlers had become lost after sailing from nearby Piagailoe Atoll on June 19, 2018. The journey from the atoll to Guam was only supposed to take one day — meaning the paddlers, who had minimal supplies had been missing at sea for nearly a week.
Following the location of the canoers from the USAF B-52H, the six-member crew of the ocean-going canoe rendezvoused with a merchant vessel in the area that was directed to their location to effect rescue. The merchant vessel provided the canoers with water, food and navigational assistance so they could safely return to land.
The eight-engine, long range B-52H bomber joined the search when the crew from Barksdale Air Force Base, La., was on a routine flight during a deployment to Guam. The heavy bomber crew responded to a call from the Coast Guard for assistance in the search on June 25, 2018.
Crew members flying a B-52H Stratofortress assigned to the 20th Expeditionary Bomb Squadron, stationed at Barksdale Air Force Base, La., and deployed to Andersen AFB, Guam, successfully located six passengers who had been missing for six days and relayed their location to the U.S. Coast Guard.
“This was a unique situation for us,” Capt. Sean Simpson, one of the bomber’s crew, said in an Air Force statement. “It’s not every day the B-52 gets called for a search and rescue.”
Initially the crew of the B-52H was unfamiliar with the type of vessel they were searching for. Coast Guard personal compared the small, difficult to spot indigenous canoe with the boat from the Disney cartoon “Moana”. Capt. Simpson told media, “We asked for more details about the vessel and the dispatcher told us, ‘It’s just like the boat from [the Disney film] ‘Moana.'”
The B-52H crew were able to locate the canoe and its crew at sea only three hours after being called into the search and rescue operation.
“We spotted this vessel from about 19,000 feet,” 1st Lt. Jordan Allen told Air Force media in the statement. “It’s really a small miracle that we were able to see it, because there was quite a bit of clouds.”
The lost canoe was located by the crew from one of the B-52H after it was compared to a similar one that appeared in a Disney cartoon.
“Search and rescue isn’t something people typically think of when they talk about the B-52, but our training and adaptability really paid off,” Lt. Col. Jarred Prier, the bomb squadron’s director of operations, said in the statement. “Being a part of this successful search and rescue operation speaks to the diversity of our skill set and shows our importance here in the Pacific.”
While the 63-year old Boeing B-52 Stratofortress, first flown in 1952 and accepted into the Air Force in 1955, is oddly well suited for the maritime search and rescue role even though it was introduced as a global reach strategic nuclear bomber. The aircraft has an extremely long combat radius of 4,480 miles, meaning it can search out in a straight line 4,480 miles and return the same distance without refueling. Given midair refueling availability, the B-52’s endurance is limited mostly by its crew’s physical endurance.
In January 1957 three USAF B-52s set an endurance record by becoming the first jet aircraft to circle the earth on a non-stop flight. The early version B-52Bs flew continuously for 45 hours and 19 minutes. In total the planes flew 24,345 miles without landing.

A new report compiled by U.S. Senate researchers warns that Russia has been emboldened by its efforts to interfere in U.S. and European elections, and calls for a stronger U.S. response to deter Moscow.
The report, released Jan. 10 by staff members of the Senate Foreign Relations Committee, listed a series of policy recommendations to counter what it called “Russian President Vladimir Putin’s nearly two-decade-long assault on democratic institutions, universal values, and the rule of law across Europe and in his own country.”
The document highlighted various efforts by European governments to counter what researchers called Kremlin policies.
For the United States, the report calls for establishing a single government body to coordinate the U.S. response to Kremlin operations, publicizing assets and wealth held by Kremlin officials and politically connected businessmen in the West, and formalizing various Russia-related sanctions programs into a single designation: “State Hybrid Threat Actor.”
Other recommendations include working more closely with U.S. allies in Europe on a joint approach to deterring Russia and cyberthreats, pressing social-media companies like Facebook and Twitter to be more transparent in political advertising, and reducing European imports of Russian natural gas and oil.
But the report also strongly criticizes President Donald Trump’s administration, saying its response has emboldened Moscow.
“Never before in American history has so clear a threat to national security been so clearly ignored by a U.S. president,” it says.
The White House did not respond to requests for reaction to the report.
In the past, Trump officials have given mixed messages about how to deal with Russia, with Trump himself espousing more conciliatory policies, while others backing stronger responses, including financial sanctions and more U.S. military weaponry for European allies.
The Republican-controlled Congress, meanwhile, has pushed forward with Russia-related legislation, largely in response to the U.S. intelligence agencies’ finding that Moscow actively meddled in the 2016 presidential election.
In August, lawmakers passed the Countering America’s Adversaries Through Sanctions Act overwhelmingly and the measure was reluctantly signed into law by Trump.
Russia has repeatedly denied any effort to interfere in the 2016 presidential election.
On Jan. 8, Deputy Foreign Minister Sergei Ryabkov rejected assertions by CIA chief Mike Pompeo that Moscow planned to meddle in the November 2018 elections that will determine whether the Republicans retain control over both houses of Congress.
The report was authored by staffers working for Democratic members of the Senate Foreign Relations Committee, and commissioned by the panel’s lead Democrat, Ben Cardin, an outspoken critic of the Kremlin.
Asked at a briefing on Jan. 9 why Republican committee staffers or members were not involved in the report, staffers insisted that Republicans would be supportive its findings and recommendations.

A new movie uses an all-star cast to bring the Battle of the Atlantic to life this Friday.
“Greyhound,” a WWII film, stars Hollywood favorite Tom Hanks, who also helped write the screenplay. It was initially set for release in theaters, but the coronavirus pandemic forced delays until it found an ultimate home exclusively on Apple TV+.
A large portion of the movie was shot on the USS Kidd (DD-661), now serving as a museum in Baton Rouge, Louisiana.
The film, which hails from the book, “The Good Shepard” (1955) by C.S. Forester, tells the story of a newly-appointed ship captain (Hanks) and his crew’s vantage point through the Battle of the Atlantic. The 1942 event involved U.S. destroyers being attacked by a series of U-boats on their way to deliver supplies to Allied Forces in Europe.
“The Battle kind of fades into the background. You don’t really think about the logistics and dangers in it,” said Tim NesSmith, USS Kidd Museum superintendent and educational outreach coordinator. “It ran the length of the entire war. It was a long, drawn out, dangerous battle – against not only the enemy, but the elements of cold and ice. I hope [the movie] will bring more attention to the people who lived it.”
Considered to be the most accurate remaining destroyer from the war, the museum is a time machine, transporting visitors back 80 years and sharing the personal stories of the experience of sailors of the time.
One of four Fletcher-class destroyers that now exist as museums, the Kidd is the only ship to maintain its original WWII layout. It’s also listed by the Historic Naval Ships Association as one of the most authentically restored vessels in the world.
“Most have been modernized or structurally updated with the times,” said NesSmith.
The USS Kidd’s target restoration date is August 1945, which calls for scheduled restorations, cleanings and refurbished pieces. This schedule allowed the ship to remain as historically accurate as possible for the film NesSmith said.
After three months of prep work, the movie was filmed throughout April of 2018 on the Kidd. Other parts of the film were shot at the nearby Celtic Media Center. During the filming, NesSmith served as the site coordinator, outlining protocol by actors and crewmember and ensuring that the Kidd was not damaged.

Film director, Aaron Schneider began scouting the Kidd for their shoot 2016.
“He researched it very well,” said NesSemith. “I think it really starts at the top and works its way down. I’ve worked on smaller sets before and this was on a whole different level. There’s a lot of planning – a lot more planning than I anticipated there would be. They did a great job.
“Everyone was really concerned about what they could and couldn’t do on the ship because they didn’t want to destroy its historical accuracy.”
Some pieces of the ship were recreated, while duplicate parts were documented and rented to the crew during filming. Museum workers also worked to obtain parts from the USS Orleck (DD-886), a fearing-class destroyer, now a museum ship, that’s based in Orange, Texas.

On Greyhound’s release, NesSmith said WWII is important to remember. For him, its importance lies in average folks coming together in large numbers in order to create “the greatest fighting force that had ever been seen at that time.”
“They created freedom for those who lost it, and it’s an important story that needs to be told.”
