Even after decades of observations and a visit by NASA’s Voyager 2 spacecraft, Uranus held on to one critical secret — the composition of its clouds. Now, one of the key components of the planet’s clouds has finally been verified.
A global research team that includes Glenn Orton of NASA’s Jet Propulsion Laboratory in Pasadena, California, has spectroscopically dissected the infrared light from Uranus captured by the 26.25-foot (8-meter) Gemini North telescope on Hawaii’s Mauna Kea. They found hydrogen sulfide, the odiferous gas that most people avoid, in Uranus’ cloud tops. The long-sought evidence was published in the April 23, 2018, issue of the journal Nature Astronomy.
The detection of hydrogen sulfide high in Uranus’ cloud deck (and presumably Neptune’s) is a striking difference from the gas giant planets located closer to the Sun — Jupiter and Saturn — where ammonia is observed above the clouds, but no hydrogen sulfide. These differences in atmospheric composition shed light on questions about the planets’ formation and history.
“We’ve strongly suspected that hydrogen sulfide gas was influencing the millimeter and radio spectrum of Uranus for some time, but we were unable to attribute the absorption needed to identify it positively. Now, that part of the puzzle is falling into place as well,” Orton said.
The Gemini data, obtained with the Near-Infrared Integral Field Spectrometer (NIFS), sampled reflected sunlight from a region immediately above the main visible cloud layer in Uranus’ atmosphere.
“While the lines we were trying to detect were just barely there, we were able to detect them unambiguously thanks to the sensitivity of NIFS on Gemini, combined with the exquisite conditions on Mauna Kea,” said lead author Patrick Irwin of the University of Oxford, U.K.
No worries, though, that the odor of hydrogen sulfide would overtake human senses. According to Irwin, “Suffocation and exposure in the negative 200 degrees Celsius [392 degrees Fahrenheit] atmosphere made of mostly hydrogen, helium, and methane would take its toll long before the smell.”

The Islamic Republic of Iran was America’s original nemesis in the Middle East before Saddam’s Iraq stole the spotlight from 1990-2003. (Saddam and the Iranians, by the way, fought a bloody 8-year war against each other in the 1980s.) A casual observer might assume that the Islamic Republic of Iran must be best buddies with the infamous Islamic State (ISIS)…but no, they share a mutual hatred of each other.
Yeah, it’s all a bit complicated and messy, so strap in, and we’ll clear things up a bit.
Iran is a theocracy, meaning the country is governed by religious law. Rather than a single strongman dictator, Iran is ruled by a group of religious clerics who control the country’s “elected” leaders like former president Mahmoud Ahmadinejad (remember him?) Iran became the Islamic Republic of Iran in 1979 after religious fundamentalists overthrew the secular government of Shah Reza Pahlevi.
The Shah was a dictator, albeit one less brutal than the current regime, who came to power in 1954 with the help of the American CIA. It was a bad look for Uncle Sam, and many Iranians never forgot it.

The Iranians are not Arabs like their neighbors to the west. Rather, they are Persians. Instead of Arabic, they speak a dialect of Persian called Farsi. The Iranians are predominantly Shia Muslims, whereas most Arabs are Sunni Muslims.
Theologically, Shias and Sunnis are akin to Protestants and Catholics in the Western world. 85-90% of Muslims worldwide are Sunni and, while the world’s Shia are concentrated in Iran, there are Shia minorities throughout the Arab world. Iraq is unique because it has both an Arab majority and a Shia majority, giving Iran a prime opportunity for heavy influence there (check the news…)
Al Qaeda and the Islamic State are Sunni jihadist groups, whereas Hezbollah in Lebanon, the Houthis in Yemen, and many of the large militias in Iraq are Shia.

So the Iranians are Persians and not Arabs, and their leaders are fundamentalist Muslims but from the opposite branch of Islam than bin Laden and the Islamic State.
So what’s Iran’s game plan? In a nutshell, Iran wants to preserve and spread its “Islamic revolution” by boxing out the Sunni Arabs and supporting Shia groups across the Middle East (they also work with certain Sunni groups like Hamas.)
To dominate the Middle East, Iran’s leaders want to exploit the “Shia Crescent,” a network of Shia populations stretching from the Persian Gulf to Lebanon. Iran’s message to these Shia populations is “Big Brother Iran is here to save you from the Sunnis, the Israelis, and the Americans.”

You can think of the fight against ISIS as World War II, with ISIS filling the role of Nazi Germany. During WWII, the Western Allies and the Soviet Union set aside their rivalries to defeat a common threat. The Defeat-ISIS campaign was similar in that Iran’s Shia coalition shared a mutual enemy with the American/Sunni alliance, even though the two sides weren’t officially partners.
But now, like in 1945, the old rivalries are back in play once again. On one side, Iran leads Syria, Hezbollah in Lebanon, the Houthis in Yemen, and other Shia factions in the region. Opposing them are the Sunni Arab countries aligned with the United States.
Fear and mistrust of Iran runs deep in countries like Saudi Arabia- so deep, in fact, that Saudi Arabia has reportedly made secret arrangements with Israel to counter the Iranian threat (that’s, uh, a plot twist…to put it mildly.) Iraq, with its Shia majority but close and complicated relationship with the United States, remains stuck in a tug-of-war between the rival coalitions.

Iran was once the great ancient empire of Persia, and there is more to modern Iran than its leaders’ ambitions. Iran has a population of over 80 million, and resentment toward the regime is widespread. Strict religious tyranny and a weak economy cause frequent protests which the Iranian regime suppresses with ruthless violence. It’s unclear if this unrest will eventually put the regime’s power in serious jeopardy.
Iran’s economic problems are driven in part by economic sanctions imposed by the U.S. and Europe. These sanctions, in turn, are imposed partly as a result of Iran’s nuclear program- a program which, the regime insists, is strictly for domestic energy production. Iran’s alleged quest for nuclear weapons is concerning because an atomic Iran could lead its Sunni rivals to pursue their own nuclear weapons.

Further Iranian vs. American bloodshed seems to have been averted in the immediate aftermath of the U.S. assassination of Iranian general Qasem Soleimani, but violence between the two countries is nothing new.
The infamous 1983 Beirut bombing, which killed 241 U.S. servicemen, was perpetrated by an Iranian suicide bomber and 1988’s “Operation Praying Mantis” pitted the U.S. Navy against the Iranian Navy in the largest American naval combat operation since WWII. The whole region remains a Game of Thrones-tier snake pit of conflicting loyalties, religious conflict, and political scheming.
Hopefully now, however, you better understand what led to the U.S. government ordering a drone strike on that guy who looked like Sean Connery.

The violence of the final weeks of World War II on Europe’s Eastern Front was matched only by its chaos, as exhausted and outmanned German forces withered under attacks from well-equipped and highly motivated Soviet troops.
The front line became more fluid, with Soviet forces quickly enveloping Nazi units that then made shambolic retreats and launched desperate breakout attempts.
At times, Soviet forces arrived at vacated German positions so quickly that the Russians found opportunities to taunt their reeling enemies.
The Soviet race to Berlin began on April 15 from positions east of the city, and by the morning of April 21, 1945, staff officers at the German army and armed forces joint headquarters at Zossen, south of Berlin, were girding themselves for capture after Hitler denied a request for them to relocate away from the Soviet advance.
But Soviet tanks ran out of gas south of the headquarters, and the delay allowed Hitler’s staff to reconsider, ordering the headquarters to move to Potsdam, southwest of Berlin. The officers at Zossen got the order just in time.
“Late that afternoon, Soviet soldiers entered the concealed camp at Zossen with caution and amazement,” historian Antony Beevor writes in his 2002 book, “The Fall of Berlin 1945.”
Just four German defenders were left. Three surrendered immediately. The fourth was too drunk to do anything.
“It was not the mass of papers blowing about inside the low, zigzag-painted concrete buildings which surprised [the Soviets], but the resident caretaker’s guided tour,” according to Beevor. The tour, he writes, took the Soviet troops down among the two headquarters’ maze of bunkers, filled with generators, maps, and telephones.
“Its chief wonder was the telephone exchange, which had linked the two supreme headquarters with Wehrmacht units,” Beevor writes.
“A telephone suddenly rang. One of the Russian soldiers answered it. The caller was evidently a senior German officer asking what was happening,” Beevor writes. “‘Ivan is here,’ the soldier replied in Russian, and told him to go to hell.”
Soviets troops found other ways to taunt the Germans using their own phone lines.
A few days later, as Russian armies advanced to the outskirts of Berlin, the senior officers in the Fuhrer bunker, which didn’t have proper signaling equipment, were increasingly in the dark about troop movements. In order to supply Hitler with up-to-date information, they had to turn to Berlin’s residents.

“They rang civilian apartments around the periphery of the city whose numbers they found in the Berlin directory,” Beevor writes.
“If the inhabitants answered, they asked if they had seen any sign of advancing troops. And if a Russian voice replied, usually with a string of exuberant swearwords, then the conclusion was self-evident.”
In the final days of April 1945, Berliners started calling their city the “Reich’s funeral pyre,” and Soviet troops were calling them to rub their looming victory in to their nearly vanquished enemy.
“Red Army soldiers decided to use the telephone network, but for amusement rather than information,” Beevor writes.
“While searching apartments, they would often stop to ring numbers in Berlin at random. Whenever a German voice answered, they would announce their presence in unmistakable Russian tones.”
The calls “surprised the Berliners immensely,” wrote a Soviet political officer.
Amid those taunts, the battle for Berlin and the fighting that preceded it left widespread destruction and death.
Soviet forces lost about 70,000 troops in the fight for the city. Many of their deaths were caused by the haste of the Soviet operation, which was driven by commanders’ desire to impress and please Stalin and by Stalin’s own desire to seize Nazi nuclear research.

Personally nominated for the Nobel Prize a record 84 times, Arnold Johannes Wilhelm Sommerfeld was one of the most influential physicists of all time, both because of his own accomplishments in the field and the many dozens of his students who turned into superstars in the world of science (including having four doctoral students go on to win the Nobel Prize, along with three of his other postgraduate students also taking home the award- the most eventual Nobel laureates all taught by one person).
Born on December 5, 1868 in Königsberg, East Prussia, Sommerfeld began his career as a student of mathematics and the physical sciences at Albertina (aka University of Königsberg) in his hometown, where he received a Ph.D. on October 24, 1891.
After a year of compulsive military service ended in 1893, unlike so many academics of his era, Sommerfeld continued to serve as a volunteer for the next eight years on the side. Physically impressive, with a Prussian bearing and wearing a fencing scar on his magnificently mustachioed face, while in the service, Sommerfeld was famously described as managing “to give the impression of a colonel of the hussars,” rather than a book-worm academic.
As for that scar, in his first year of study, the near “compulsory drinking bouts and fencing duels” not only resulted in said scar, but also hindered his studies significantly, which he later came to regret as wasted time.
Apparently making up for lost efforts in his youth, Sommerfeld left Königsberg for the University of Göttingen and after two years as an assistant to more experienced mathematics professors, he earned his Privatdozent (authorization to teach at the university level) in 1895. Rapidly moving up the ranks, he was appointed to chair the mathematics department at the Bergakademie in Clausthal-Zellerfeld in 1897. The following year, he became editor of the famous Enzyklopädie der mathematischen Wissenschaften, a post he held through 1926.
Sommerfeld moved on to become Chair of Applied Mechanics at the Königliche Technische Hochschule Aachen, and it was in Aachen that he produced his theory of hydrodynamics. Also at Aachen, Sommerfeld mentored Peter Debye, who later won the Nobel Prize in Chemistry in 1936 for “his contributions to the study of molecular structure.”
In 1906, Sommerfeld accepted the position as director of the new Theoretical Physics Institute at the University of Munich, where he mentored Werner Heisenberg in hydrodynamics theory; Heisenberg later won the Nobel Prize in Physics in 1932 “for the creation of quantum mechanics.”
While in Munich, Sommerfeld also mentored Wolfgang Pauli on his thesis on quantum theory, and Pauli also went on to win a Nobel Prize in Physics, in 1945, for his discovery of the eponymous Pauli exclusion principle (which stated that two or more identical fermions can not be in the same quantum state within a quantum system at the same time).
If all that wasn’t enough, he also mentored Hans Bethe while at the University of Munich; Bethe was awarded the Nobel Prize in Physics in 1967 for his theory of stellar nucleosynthesis (i.e., when chemical elements in stars change due to nuclear fusion).
While his own direct contributions to advancing the world of physics were prodigious, including his pioneering work in quantum theory, it was arguably for his teaching ability that Sommerfeld was most revered in his lifetime, with Albert Einstein once remarking, “What I especially admire about you is that you have, as it were, pounded out of the soil such a large number of young talents.”
Mathematician Morris Kline further stated of Sommerfeld that he “was at the forefront of the work in electromagnetic theory, relativity and quantum theory and he was the great systematizer and teacher who inspired many of the most creative physicists in the first thirty years of this century.”
Famed Jewish mathematician, physicist, and Nobel Prize winner Max Born (who was forced to flee Germany in 1933) went on about Sommerfeld’s talent for cultivating young minds who so often went on to great scientific achievements of their own:
Theoretical physics is a subject which attracts youngsters with a philosophical mind who speculate about the highest principles without sufficient foundations. It was just this type of beginner that he knew how to handle, leading them step by step to a realisation of their lack of actual knowledge and providing them with the skill necessary for fertile research. … He had the rare ability to have time to spare for his pupils, in spite of his duties and scientific work. … In this friendly and informal way of teaching a great part was played by invitations to join a skiing party on the ‘Sudelfeld’ two hours by rail from Munich. There he and his mechanic … were joint owners of a ski hut. In the evenings, when the simple meal was cooked, the dishes were washed, the weather and snow properly discussed, the talk invariably turned to mathematical physics, and this was the occasion for the receptive students to learn the master’s inner thoughts.
Going on about the man himself, Born stated,
Arnold Sommerfeld was one of the most distinguished representatives of the transition period between classical and modern theoretical physics. The work of his youth was still firmly anchored in the conceptions of the nineteenth century; but when in the first decennium of the century the flood of new discoveries, experimental and theoretical, broke the dams of tradition, he became a leader of the new movement, and in combining the two ways of thinking he exerted a powerful influence on the younger generation. This combination of a classical mind, to whom clarity of conception and mathematical rigour are essential, with the adventurous spirit of a pioneer, are the roots of his scientific success, while his exceptional gift of communicating his ideas by spoken and written word made him a great teacher.
Adding to his list of achievements, Sommerfeld eventually became chair of the Deutsche Physikalische Gesellschaft in 1918, a position previously held by Albert Einstein.
With the rise of the Nazi party in Germany, however, Sommerfeld was forced to watch many of his esteemed colleagues have to flee the country. As the aforementioned Morris Kline notes,
Sommerfeld’s life was saddened toward the end of his career by events in Germany. Anti-Semitism, always present in that country, became virulent in the Hitler period and Sommerfeld was obliged to witness the emigration of famous colleagues, including Einstein. All he could do was use the friendships he had built up during a one-year stay in the United States and a one-year round-the-world trip to help place the refugees. The loss of so many of its best men in this way together with World War II, destroyed the scientific strength of Germany, and Sommerfeld felt obliged to continue teaching until 1947, long after the usual retirement age of 65.
On that note, Sommerfeld had intended to retire much earlier, in 1936, putting forth one of his prized pupils, the aforementioned Nobel Prize winner Werner Heisenberg, as his hoped successor. However, as Heisenberg, like Sommerfeld, was considered by the Nazi party to be a Jewish sympathizer, ultimately the decidedly unaccomplished anti-Semite Wilhem Muller, with a lot of help from the Reich Education Ministry, was very controversial appointed to replace Sommerfeld as Professor of Theoretical Physics, despite Muller not even being a theoretical physicist. (Unsurprisingly, Muller was dismissed from the position in 1945 as a part of the denazification process that followed WWII.)
As for Sommerfeld’s once patriotic views, he wrote to Einstein shortly after Hitler took power,
I can assure you that the misuse of the word ‘national’ by our rulers has thoroughly broken me of the habit of national feelings that was so pronounced in my case. I would now be willing to see Germany disappear as a power and merge into a pacified Europe.
In any event, as for his own Nobel Prize aspirations, as alluded to, Sommerfeld’s contributions to theoretical physics were many and included groundbreaking work in quantum theory (including co-discovering the Sommerfeld-Wilson quantization rules in 1915), electromagnetism and hydrodynamics, and significantly advanced knowledge of X-ray wave theory, among other things.
Among his many awards were the Max-Planck Medal, the Lorentz Medal and the Oersted Medal, and he was also a member of the Royal Society, the U.S. National Academy of Sciences, the Indian Academy of Sciences and the Academy of Sciences of the USSR.
However, although he was nominated an astounding and record setting 84 times (the only other person close is Otto Stern, who was nominated 82 times before finally winning in 1943), Sommerfeld never won a Nobel Prize. His nominations for Physics were made in 1917, 1918, 1919 (twice), 1920, 1922 (four times), 1923 (twice), 1924, 1925 (six times), 1926 (three times), 1927 (three times), 1928 (three times), 1929 (nine times), 1930 (four times), 1931 (twice), 1932 (five times), 1933 (eight times), 1934 (six times), 1935, 1936 (twice), 1937 (eight times), 1940, 1948, 1949 (three times), 1950 (three times) and 1951 (four times).
Sommerfeld died on April 26, 1951 at the age of 82 as a result of a traffic accident that occurred while taking his grandchildren for a walk. At the time, he was quite hard of hearing and did not hear shouted warnings before he stepped in front of a moving truck. The distinguished scientist died two months later as a result of the injuries sustained in that incident.

For the third time in a week, the Arleigh Burke-class guided-missile destroyer USS Mason came under attack off the coast of Yemen by Iran-backed insurgents.

The Mason and Nitze have been involved in three missile ambushes by Iran-backed Houthi rebels off the coast of Yemen in recent weeks. (U.S. Navy photo by Mass Communication Specialist 3rd Class Ryan U. Kledzik/Released)
As was the case in the previous attacks, the incoming missiles were apparently fired by Houthi rebels late Saturday night and did not hit the destroyer. Yemen is about 7 hours ahead of the East Coast of the United States.
According to a report by NBC News, the Mason used countermeasures to avoid being hit. The previous attacks on Oct. 9 and Oct. 12 apparently used Noor anti-ship missiles, an Iranian copy of the Chinese C-802. In the Oct. 9 incident, USS Mason used a Nulka decoy as well as an SM-2 and Evolved Sea Sparrow Missiles to defeat the attack.
The second attack was defeated using what a DOD statement termed as “defensive countermeasures.”
The Pentagon reported the radar stations were destroyed, but there had been speculation that the Houthi rebels used personnel in small boats or skiffs to spot targets for the anti-ship missiles.
Iran responded to the attack by deploying at least two surface combatants off the coast of Yemen.
The Mason and Nitze were deployed near Yemen with the USS Ponce (AFSB(I) 15) after the former Navy high-speed transport HSV-2 Swift was attacked by Houthi rebels using RPG rockets. At least two of the anti-tank rounds hit the Swift, which suffered a fire, and has been towed from the area.
In a statement after the Nitze launched the Tomahawks against the Houthis, Pentagon Press Secretary Peter Cook warned, “The United States will respond to any further threat to our ships and commercial traffic, as appropriate, and will continue to maintain our freedom of navigation in the Red Sea, the Bab al-Mandeb, and elsewhere around the world.”
Apparently, the Houthi didn’t think the United States was serious.
On April 6, 2008, two Special Forces operational detachments and more than 100 Afghan commandos began an air assault into a mountain fortress above the Shok Valley.
Six and a half hours later, two members of the assault were killed and nine seriously wounded, over 100 enemy fighters were dead or captured, and eleven men had earned some of the nation’s highest awards for valor. This is what happened.
Entering Shok Valley
The assault was to capture leaders in Hezeb Islami al Gulbadin, a regional insurgent group in Afghanistan. The targets were holed up in a mountain top village surrounded by farm terraces and tall cliffs, providing tough ground for an assaulting force to cover. The village itself was made of strong, multistory buildings that would provide defenders cover while allowing them to fire out.
The American and Afghan force flew to the valley in helicopters. Their initial plan called for a quick insertion close to the village so they could assault while they still had the element of surprise. Their first landing zone was no good though, and so they were dropped into a nearby river and forced to climb up from there. The delay allowed insurgent forces to set up an ambush from the high ground.
Combat breaks out
After the helicopters departed, enemy fighters directed automatic weapon and rocket fire on the American and Afghan National Army soldiers. Their interpreter was killed almost immediately and the communications sergeant, Staff Sgt. Dillon Behr, received a life-threatening wound to his leg. He continued fighting, attempting to suppress some of the incoming fire.
Meanwhile, the assault team had already reached the village, and so found themselves cut off when the forces behind them began taking fire. Despite the precarious position he and the lead Afghan commandos were in, Sgt. David Sanders began relaying the sources of incoming fire to the Air Force joint tactical air controller on the mission.
The mission commander, Capt. Kyle Walton, told an Army journalist later that year about the initial bombings on the target. They were all danger close, meaning friendly forces were within range of the bombs’ blast.
“I was standing next to the combat controller, and when we got to a place where we could talk, he called in close air support, and the F-15s rolled in immediately. I knew my guys were up there, and I know that when you call in danger close air, you are probably going to get injured or killed. I called back to Sanders and asked if he was too close. He said, ‘Bring it anyway.’ Bombs started exploding everywhere. When I called to see if he was still alive, all I could hear him saying was, ‘Hit them again.’ ”
The Air Force JTAC, Airman Zachary Rhyner, would go on to call over 70 danger close missions that day, using eight Air Force planes and four Army attack helicopters to achieve effects on the target.
Three-story explosion and sniper warfare
As the battle continued to rage, both sides were using controlled, focused fire to wound and kill enemies. But a massive explosion after an American bomb hit a three-story building in the village brought on a brief lull in the fighting.
“Good guy or bad guy, you’re going to stop when you see that,” Staff Sgt. Luis Morales, a Special Forces intelligence sergeant, told the Army. “It reminded me of the videos from 9/11 — everything starts flushing at you, debris starts falling — and everything gets darker.”
The Americans and Afghan commandos used this time to consolidate some of their forces.
Both before and after the explosion, snipers on each side were playing a key role. For the Americans, one of their top assets was Staff Sgt. Seth E. Howard, a Special Forces weapons sergeant.
Near the command node, Howard was well-positioned to see the enemy fighters draw close to Walton and the JTAC. To prevent them being killed or captured, Walton stepped away from his position and moved into the open to engage the advancing fighters. He halted their advance, allowing Rhyner to continue calling in bombs.
Rhyner’s bombs would also be instrumental in protecting the command node. He sometimes had to order bombs within 100 meters of his and Walton’s position.
Planning to leave
American forces and Afghan commandos had more problems as the day wore on. The weather at the outset of the mission had been tricky, but the team was getting reports that a dust storm was getting worse and would stop air support before nightfall. That would leave them without bombs, helicopters, or an exit strategy. Meanwhile, surveillance platforms showed another 200 enemy fighters moving to the battlefield.
Walton had requested medical evacuation multiple times, but enemy fire made it impossible. And with six seriously wounded men, a closing window to exit the battlefield, and the serious danger of being overrun, Walton began looking at pulling the team out. But there was a problem. The initial plans had called for the team to leave by descending back down the terraces, a route now closed due to intense enemy fire.
Sanders had managed to break out of his besieged position in the village when another green beret forced a route open. Now, Walton asked him to recon a route down the sheer cliffs to the north of the village.
Sanders told the commander that the route was bad and it was possible that some climbers might break their backs or necks attempting it, but they’d probably live. The situation was so dire, Walton approved it as an exit strategy.
Leaving Shok Valley under heavy fire
Team Sergeant Master Sgt. Scott Ford led the organization at the top of the cliffs. He had less wounded team members carry the more seriously wounded down. One team member made the climb while carrying his leg that had been amputated by a sniper round early in the battle. Others were nursing wounds sustained from both insurgent fire and the effects of all the “danger close” bomb drops.
Ford was defending the top of the cliff other soldiers were climbing down when he was struck in the chest plate by a sniper round. He jumped up and continued fighting, but he was struck again. This time, his left arm was nearly amputated. Ford then finally began his own climb down the mountain, continuing to lead his men as he did so.
Howard, the sniper from above, stayed until all the other Americans and the Afghan commandos had left the mountain. He defended the top of the cliffs with his last magazine before pulling out.
One Afghan commando and an interpreter died, but all of the Americans survived the battle. The Army estimated the insurgents suffered over 150 dead and an untold number of wounded, according to an Army article. Eight insurgents were captured.
After the battle
Many of the wounded members of the team returned to service, including Ford and Sgt. 1st Class John Walding, the team member who lost his leg early on and carried it down the cliffs. Walding is attempting to return to his team, an ambition he describes near the end of this Army video about the battle. He later became the first amputee to graduate the Special Forces Sniper Course.
In a ceremony on Dec. 12, 2008, 10 members of the team were awarded Silver Stars. Rhyner was awarded the Air Force Cross during a separate ceremony in 2009.
While everyone likes to talk about how scary the Spartans or Romans could be, it was the Mongols who pioneered new warfare tactics, used them to win battle after battle, and survived on a diet of horse blood and liquor to ride across whatever terrain they needed to in order to murder you.
The Mongols, made most famous by Genghis Khan after he established an empire in 1206, were centered in the steppes of central Asia. The empire would eventually cover over 9 million square miles, making it the largest land empire in world history.
Mongols during the Siege of Vladimir
Mongol success was due to a number of factors. They could be ruthless, allowing them to press the attack when most would back off. They had a good division of labor, with women taking on many camp and political duties while the men did the bulk of the fighting with few distractions. And their societal ties to horses made them highly mobile. So highly mobile that, in battle, they were some of the pioneers of “localized superiority of numbers,” a force concentration strategy where a smaller force could dominate a larger one by outnumbering the larger force at key points.
Basically, it doesn’t matter if you have three times the forces in the region if I have three times the forces at the objective — my team’s horses allow us to quickly hit objective after objective while your marching brethren are still plodding along the roads.
Mongol horsemen fighting Chinese forces.
In one case in 1223, two of Genghis Khan’s lieutenants were riding with 20,000 men against 80,000 Russian troops. The horsemen conducted a controlled withdrawal, and the Russians pursued sloppily, allowing their column to get stretched out. After a week, the Russians were split up and the horsemen turned around, slamming their 20,000 troops against a couple thousands Russians at a time. The Mongols won handily, using bows and lances to kill Russian after Russian.
But as the Mongol Empire went to expand, the terrain began to limit them. Horse armies are perfect for traversing grasslands covered in animals, and are even good for mountains and forests, but trying to cross the most sparse parts of Asia was near impossible. The horde could face days of hard riding with barely enough food to sustain a few horsemen, let alone the 20,000 or more in the horde.
For instance, the 1223 attack against Russian forces required that the Mongols cross miles and miles of grasslands for days. They carried dried horse milk, dried meat, dried curds. Sure, it doesn’t sound appealing, but it could keep you going on the march.
But that would only buy the Mongols a few days. Since they also liked getting drunk, they usually carried horse liquor, which packed a lot of calories for relatively little weight. So, yeah, when the Mongol Horde rode out of the mists to slaughter you, they were drunk on horse when they did it.
Mongol archers were some of the best in the world, and they could easily do their jobs from horseback.
But for even longer rides, famed explorer Marco Polo said things took a turn for the darker. See, the horsemen would get almost no sustenance from eating grass. It passes through the human digestion system while leaving almost no calories or nutrients behind.
But horses can eat grass just fine; it’s one of their primary foods. And so, in a pinch, the Mongols would cut a vein in their horse’s necks at the end of every day, taking a few swallows of blood that the horse could easily replace. It wasn’t much, but it allowed them to cross the grasses to the west and hit Russia and additional empires.
On the even darker side, they also allegedly ate human flesh when necessary. Even killing the attached human if horses and already-dead people were in short supply. So, you know, the Mongols were the monsters you heard about in history. But they were also tactical masterminds who embraced technology and strategy.
With the assistance of allied hackers, Russia has developed a cyberweapon capable of destroying an electricity grid, US researchers report that such a weapon could be used to upset the American electric system.
The reports say that the devise was used to disrupt energy system in Ukraine December in 2015.
According to the Washington Post, the cyberweapon has the potential to be the most disruptive yet against electric systems that Americans depend on for daily life.
The malware, which researchers have dubbed CrashOverride, is known to have disrupted only one energy system — in Ukraine in December, 2015.
In that incident, the hackers briefly shut down one-fifth of the electric power generated in Kiev.
But with modifications, it could be deployed against US electric transmission and distribution systems to devastating effect, said Sergio Caltagirone, director of threat intelligence for Dragos, a cybersecurity firm that studied the malware and issued a report on June 12th.
And Russian government hackers have shown their interest in targeting US energy and other utility systems, researchers said.
“It’s the culmination of over a decade of theory and attack scenarios,” Caltagirone warned. “It’s a game changer.”
The revelation comes as the US government is investigating a wide-ranging, ambitious effort by the Russian government last year to disrupt the US presidential election and influence its outcome.
Dragos has named the group that created the new malware Electrum, and it has determined with high confidence that Electrum used the same computer systems as the hackers who attacked the Ukraine electric grid in 2015.
That attack, which left 225,000 customers without power, was carried out by Russian government hackers, other US researchers concluded.
US government officials have not officially attributed that attack to the Russian government, but some privately say they concur with the private-sector analysis.
“The same Russian group that targeted US [industrial control] systems in 2014 turned out the lights in Ukraine in 2015,” said John Hultquist, who analyzed both incidents while at iSight Partners, a cyber-intelligence firm now owned by FireEye, where he is director of intelligence analysis. Hultquist’s team had dubbed the group Sandworm.
“We believe that Sandworm is tied in some way to the Russian government — whether they’re contractors or actual government officials, we’re not sure,” he said. “We believe they are linked to the security services.”
Sandworm and Electrum may be the same group or two separate groups working within the same organization, but the forensic evidence shows they are related, said Robert M. Lee, chief executive of Dragos.
The Department of Homeland Security, which works with the owners of the nation’s critical infrastructure systems, did not respond to a request for comment.
New technology from engineers at the University of Utah is changing the lives of amputees. The robotic arm, which is being called Luke in honor of Luke Skywalker’s artificial hand in The Empire Strikes Back. The robotic arm enables recipients to touch and feel again. The device consists of a prosthetic hand and fingers that are controlled by electrodes implanted in the muscles.
A prototype has been given to Keven Walgamott, an estate agent from Utah who is one of seven test subjects. He lost his hand and part of his left arm in 2002 after an electrical accident. With the arm, Walgamott has been able to complete tasks that were previously very difficult, such as put a pillowcase on a pillow, peel a banana, and even send text messages. Study leader and University of Utah biomedical engineer Professor Gregory Clark told the Independentthat one of the first things Walgamott wanted to do was put on his wedding ring. “That’s hard to do with one hand,” Clark said. “It was very moving.”
Walgamott can even feel sensations like touching his wife’s hand, as well as distinguish between different surfaces. This is not only a major scientific breakthrough, but an emotional moment for Walgamott, who’s been without his left hand for nearly 20 years. “It almost put me to tears,” he said of using Luke for the first time. “It was really amazing. I never thought I would be able to feel in that hand again.”
Now the next step is if this technology can incorporate what this real-life amputee did with her own lightsaber!

Army personnel recently traveled from Germany to the Aberdeen Proving Ground in Maryland for testing and training on new variants of the Stryker Infantry Carrier Vehicle.
The soldiers tested out Strykers armed with a 30mm cannon as well as with a common remote-operated weapons station that allows soldiers inside the vehicle to fire Javelin antitank guided missiles.
Twelve of the Stryker variants — six with 30 mm cannons and six with Javelin missiles — will head to Germany in January for more evaluation by US troops before the Army hopes to deploy them to a forward position in Europe next summer.
Troops from the 2nd Cavalry Regiment, who took part in the testing in Maryland, spoke highly of the new features on the vehicle, which has been nicknamed “Dragoon” after the regiment.
(Army News Service (ARNEWS) | YouTube)”It’s doing a lot more damage and you’re getting better effects,” Staff Sgt. Randall Engler said.
Previous variants of the Stryker have been armed with either an M2 .50-caliber machine gun or an MK19 grenade launcher. The request for more firepower came in response to recent military operations by Russia.
“This capability coming to [2nd Cavalry] is directly attributable to Russian aggression and we are actively working with our foreign partners in how to help shape our formation,” said Lt. Col. Troy Meissel, the regiment’s deputy commanding officer, according to the Army.
The new armaments don’t make the Stryker a fighting vehicle, but Meissel said the search for heaftier weapons stems from the reduction in manpower in Europe from 300,000 during the Cold War to about 30,000 now.
“How do we, as an Army, make 30,000 soldiers feel like 300,000?” Meissel said. “This new ICV-D is one of the ways that can help us do that.”

Advancements in Russian armor have been cause for concern among military planners in the West. Moscow’s new Armata tank will reportedly be outfitted with an active-protection system, which uses radar and projectiles to detect and counter antitank and anti-armor weapons.
The US Army is also looking at APS for the Stryker and its Abrams tank, though the latest variant of the RPG is rumored to have an APS countermeasure.
Relations between Russia and US allies in Eastern Europe have grown more contentious in recent months, particularly in the run up to Russia-Belarus military exercises in September that will reportedly see 60,000 to 100,000 Russian troops deployed to Belarus and western Russia.
Countries in the Baltics have warned of more ambitious Russian espionage efforts, and NATO aircraft have tangled with their Russian counterparts numerous times in over the last year.
The US has done several military exercises with partners in the region this year and increased deployments, including of Patriot missile air-defense systems, to NATO member-states in Eastern Europe.

The United States says it is halting deliveries to Turkey related to the F-35 fighter-jet program in response to Ankara’s decision to move ahead with the purchase of Russian air-defense system.
“Pending an unequivocal Turkish decision to forgo delivery of the S-400, deliveries and activities associated with the stand-up of Turkey’s F-35 operational capability have been suspended while our dialogue on this important matter continues with Turkey,” a Pentagon spokesperson said on April 1, 2019.
Washington has been warning Ankara for months that buying the S-400 system would jeopardize its planned purchase of the advanced fighter aircraft.
Turkey has said it is committed to a deal to buy S-400 missile-defense systems from Russia.
Contractor mechanics failed to follow proper maintenance procedures leading to the contamination of the oxygen system on an Air Force VC-25A aircraft undergoing regular heavy maintenance, according to an Accident Investigation Board report compiled by Air Force Materiel Command.
The contamination occurred in April 2016 while the plane was at Boeing’s Port San Antonio facility in Texas. The mishap resulted in approximately $4 million in damage, which Boeing repaired at its own expense.
The VC-25A, one of two specially configured Boeing 747-200B aircraft, is flown by the 89th Airlift Wing at Joint Base Andrews, Maryland, and is used to transport the President. When the President is on board, the plane is referred to as Air Force One.
According to the report, three Boeing mechanics contaminated the aircraft’s oxygen system by using tools, parts, and components that did not comply with cleanliness standards while checking oxygen lines for leaks. The contamination was discovered after an unapproved regulator was found connected to the passenger oxygen system.
The report also identified other contributing factors to the mishap, including the failure of a Boeing maintenance technician to observe explicit cautions and warnings when working on oxygen systems, Boeing’s failure to exercise adequate oversight of the quality of maintenance being performed on the VC-25, and the failure of mechanics to “absorb and retain” training received on oxygen systems.
Gen. Ellen M. Pawlikowski, Air Force Materiel Command commander, convened the AIB. Brig. Gen. Carl Buhler was the AIB president. The primary purpose of the board was to investigate the cause and substantially contributing factors of the mishap and provide a publicly releasable report of the facts and circumstances surrounding the incident.
Enlisted airmen have been part of the Air Force Academy in both instructor and mentor positions. But now they have a chance to be considered full time accredited faculty teachers.
The Air Force Academy was established in April 1954 after several years of consideration. Long before the Air Force was its own branch of the military, senior leadership argued they needed a school that would be directly focused on the war in the air – they needed a place to train future airmen.
In 1948, a year after the formal establishment of the Air Force, the Stearns-Eisenhower Board was formed to study existing military academies. They concluded that the Air Force absolutely needed its own school and that at least 40 percent of all future officers should be service academy graduates.
It took seven years for leadership to reach a consensus on site location and to receive funding. In 1955, construction began on the Academy in Colorado Springs. That same year, the first class of 306 officers were sworn-in at a temporary site – Lowry Air Force Base in nearby Denver, Colorado. Lt. Gen. Hubert R. Harmon was recalled from retirement by President Eisenhower to become the Academy’s first superintendent.
Women were allowed to enter the Academy beginning in 1975, and the first women cadets graduated in 1980. That flagship-class included the Academy’s first woman, who would later be superintendent, Lt. Gen. Michelle Johnson. To date, the Air Force Academy has graduated more than 50,000 officers.
Since its inception, the Air Force Academy has provided a corps of officers dedicated to upholding the standards of their profession and of the Air Force. In turn, the Academy offers cadets the right kind of access to a diverse and varied faculty. Now that faculty is even more diverse than ever.
After its first year, the Air Force Academy says that having noncommissioned officers serve as faculty shows real promise, but there needs to be further evaluation to decide if it’s worth keeping. The Academy is the first service academy that features enlisted service members as official faculty.
A report issued this summer, written by Chief Master Sgt. Sean Milligan and Senior Master Sgts. Ecaterina Garcia and Gloria Kuzmicki was released a year after the test pilot began. The Air Force reports that it will need several more years to explore the sustainability of the program, but initial findings are very promising – both for cadets and for the current faculty on staff.
The four enlisted Academic instructors, including the Chief mentioned above MSgt. Milligan, Senior MSgt. Garcia and Kuznicki, along with Senior MSgt. William Baez. Milligan manages the enlisted instructors and teaches part-time in the management department. Garcia teaches military strategy studies, Kuzmicki teaches leadership and behavior science, and Baez teaches intro statistics.
In a statement to Air Force Times, Milligan said that the program proves that the Air Force can select and hire appropriately qualified enlisted instructors to help increase faculty diversity. He went on to say that it seems like having an enlisted faculty component helps to have a positive effect on the cadets. The diversified faculty might also help cadets have a more collaborative learning environment, leading to greater career growth – not to mention significant experience with enlisted airmen.
The Air Force Academy created three enlisted teaching positions for the senior noncommissioned officers, all of whom hold advanced degrees.
After being hired, each instructor receives their department assignment and teaches classes relevant to their subjects of expertise. This initiative’s main goal is to provide enlisted airmen who have advanced degrees with a chance to put their education to work while continuing to serve the Air Force.
The report concludes that cadets will ultimately be better served with a more diverse staff. It still remains to be seen how the program will continue to unfold, but it seems clear the Air Force is committed to providing the right proving ground for America’s next generation of Air Force officers.
