Earlier this year, General Charles “CQ” Brown made history when he was appointed the first Black service chief of a U.S. military service, taking the reigns of the United States Air Force upon the departure of General David Goldfein. Now, he also holds the distinction of being listed among Time Magazine’s Most Influential People of 2020.
Brown’s appointment came at a pivotal time for the service and the country, as America continues to grapple with issues regarding race that are certainly not limited to the civilian population. In the minds of many, Brown’s appointment isn’t just representative of his incredible career and selfless service to his nation, but also an important milestone for Black service members across the entirety of the force.
“It is due to their trials and tribulations in breaking barriers that I can address you today as the Air Force chief of staff,” General Charles “CQ” Brown, upon being sworn in as Chief of Staff of the U.S. Air Force.

Brown’s selection as one of Time Magazine’s most influential people of the year isn’t just because the man represents those broken barriers, but importantly, because of character of his service, his devotion to duty, and his commitment to the Airmen under his charge.
“He is a respected warfighter who will serve America well. As the former commander of Pacific Air Forces, he’s highly qualified to deter China and reassure allies in the Indo-Pacific. The suppression of ISIS militants in Iraq and Syria was largely accomplished by local forces on the ground, enabled by air power CQ helped orchestrate.” -Former Secretary of the Air Force Heather Wilson in Time Magazine
Brown rose through the ranks as an F-16 pilot with more than 2,900 hours in the cockpit and at least 130 flight hours in combat environments. Brown’s talents in the cockpit eventually led him to serving as an F-16 pilot instructor before moving on to a variety of command positions, including his recent role as the commander of Pacific Air Forces.

Throughout his impressive career, General Brown has repeatedly stood out among his peers. First commissioned in 1984, Brown went on to earn a master’s degree in aeronautical science and was singled out at Air Command and Staff College as his class’ distinguished graduate in 1994. He has commanded Air Force Weapons School, two fighter wings, the U.S. Air Force’s Central Command, and also served as the deputy commander for U.S. Central Command.
A simmering conflict between Israel and Iran in Syria could have erupted into another regional war were it not for the intervention of Russian President Vladimir Putin, according to an Israeli investigative journalist.
On Feb. 10, 2018, an Israeli air force helicopter shot down what Israel says was an Iranian drone launched from the Tiyas Military Airbase in central Syria by Iran’s Islamic Revolutionary Guard Corps.
The drone was shot down a minute and a half after entering Israeli airspace, the investigative journalist, Ronen Bergman, wrote in an op-ed article in The New York Times.
Israel responded by sending eight F-16 fighter jets into Syria to destroy the drone’s command-and-control center. While flying back to Israel, they came under attack from Syrian anti-aircraft missiles — one of which, an S-200, took down an F-16, forcing the pilots to eject.
Israel hit back, going after Syria’s air-defense system. The Israeli military says it hit multiple Syrian and Iranian targets.
Israel has long been worried about Iran’s activities and growing influence in the region, especially in Syria, where Iran has backed pro-government forces during the country’s years-long civil war.
“The response to the downing of the Israeli jet was intended to be a lot more violent,” Bergman wrote, adding that Israeli generals brought out plans “for a huge offensive operation in Syria.”
But a “furious phone call” from Russian President Vladimir Putin, whose forces in Syria were close by, “was enough to make Prime Minister Benjamin Netanyahu of Israel cancel the plans,” Bergman wrote.
A former Israeli army general appeared to confirm Bergman’s reporting.
If the F-16 hadn’t been shot down, Israel “would be able to keep this issue at a very, very low profile,” Udi Dekel, a former Israeli army brigadier general who was the head of the Israel Defense Forces’ strategic-planning division, said Feb. 14 on a call organized by the Israel Policy Forum.
“Because we lost the F-16, we decided to respond against many important targets inside Syria,” Dekel said, among them air defenses, Syrian army positions, and Iranian positions around Damascus.
Israel wanted “to send a message that we could not accept any idea that they would try to shoot down our aircraft in our skies,” Dekel said.
Dekel said Israel did not pursue further strikes because it wanted to see the Syrian and Iranian response. But he added that there was “intervention by the Russians, who asked us not to escalate the situation anymore and to try and calm down the situation.”
These recent actions are likely to increase tensions in the Middle East — but Dekel says he doesn’t think this is the “end of the story.”
“We killed Iranians operating the UAV and in other locations, so I assume they will try to find any opportunity for revenge against us,” he said, referring to the drone with the abbreviation for an unmanned aerial vehicle.
In August 2015, Staten Island attorney Richard A. Luthmann motioned a New York State court to allow “Game of Thrones” style trial by combat to decide one of his cases. During a lawsuit, Luthmann allegedly advised a client to liquidate his assets and move the funds to where the people suing him couldn’t get to them.
His intent was to settle the civil case in “a fight to the death between either party or champions of the party” while highlighting how silly the plaintiff’s lawyers were. And less than six months later, the right to a trial by combat was upheld by the New York State Supreme Court.
In a 10-page brief, Luthmann details the rights of trial by combat in Medieval England and England’s American colonies. The motion to ban the practice was blocked by Parliament in 1774 and was not restricted by the Constitution.
Luthman also contends the practice is protected by the Ninth Amendment, which protects the rights mentioned specifically elsewhere in the Constitution.
Luthmann wrote in a brief to the New York State Supreme Court:
“The allegations made by plaintiffs, aided and abetted by their counsel, border upon the criminal, as such, the undersigned respectfully requests that the court permit the undersigned to dispatch plaintiffs and their counsel to the Divine Providence of the Maker for Him to exact His divine judgment once the undersigned has released the souls of the plaintiffs and their counsel from their corporeal bodies, personally and or by way of a champion.”
The idea of the request was to initially highlight how ridiculous it was for the party suing Luthmann’s client to then sue the counsel for his client for offering legal advice for $500,000.
Sadly for the entertainment world, Justice Minardo resolved that Luthmann’s civil suit would be settled in court, either by a judge or jury.
“I believe that the court’s ruling is based upon my adversaries’ unequivocal statement that they would not fight me,” Luthmann told Staten Island Live. “Under my reading of the law, the other side has forfeited because they have not met the call of battle. They have declared themselves as cowards in the face of my honorable challenge, and I should go to inquest on my claims.”
In the United States, hospitals are facing shortages of medical grade masks, and have taken to social media to ask seamstresses nationwide if they can sew masks for them.
When Sarah Mainwaring, a military spouse and community advocate at Robins AFB heard about the plight of local hospitals, she devised a plan to fulfill the needs of both the military community and healthcare workers due to the (very) limited availability of medical masks. She enlisted the help of her neighbors and fellow military spouses, and they began gathering materials to begin sewing masks. They decided to take their movement public by involving the military community, and thus, Milspo Mask Makers was born.
Milspo Mask Makers is a growing community movement of active duty, guard, reservists, and military spouses that are dedicated to filling the needs of healthcare workers, the surrounding community, and the immunocompromised by sewing masks to help them protect themselves against COVID-19. These masks can be used by healthcare workers in the event of a shortage, or to prolong the life of their medical mask to be able to use it longer.
Through their efforts, the ladies at Milspo Mask Makers were able to come together and sew over 100 masks in their first 24 hours. They have since been joined by other spouses in their local community, and have distributed over 200 masks to date. Sarah has challenged the military community to sew 10,000 masks worldwide and distribute them to those in need. If you or someone you know is making masks, let Milspo Mask Maker know! Use the hashtag #MilspoMaskMaker when you post photos to social media.
Also, be sure to like their page on Facebook to keep up-to-date with their efforts, view tutorials on making masks, and to find out other ways you can contribute to the cause!
The idea of a “Space Shuttle Door Gunner” has always been a joke around the military. It’s so outlandishly silly that no one would dare think it’s real.
With last year’s proposed Space Corps, the expansion of civilian space programs, and a growing need for a military presence in space to protect American assets, President Trump gave his nod to the idea of a “Space Force.” This joke may soon be reality. But there are still many roadblocks in the way – like physics, for instance.
For obvious reasons, the door would have to be closed during takeoff and landing, otherwise, friction alone would tear the shuttle apart. Tragic examples of what foam shedding and a faulty O-ring can cause means that any fighting a door gunner would see would have to occur beyond a distance from Earth to allow for EVA (extravehicular activity).
Now that the door gunner is properly outside of Earth’s atmosphere, they could begin their watch. A properly tethered door gunner could hold their post for a while. The current record for longest EVA, also known as a “spacewalk,” is held by Cosmonauts Fyodor Yurchikhin and Alexander Misurkin at 7 hours and 29 minutes. They walked outside of the International Space Station to install power and data cables — but a door gunner could hold that post for longer.
Finally, the nitty-gritty of space combat. A door gunner could easily bring modern weapons into space and, surprisingly, only have a few problems firing it. This is because modern ammunition has its own oxidizer, so no atmospheric oxygen is required. There wouldn’t be any sound (since audible sound doesn’t travel in a vacuum) and the recoil wouldn’t matter in low-Earth orbit because the shuttle would be moving at around 4 miles a second.
Tests on Earth have proven bullets fire in a vacuum. (via GIPHY)
The downsides would be that, without friction to slow down the bullet, it would travel until it hit something — the enemy, Earth, or some distant object forever away. Also, without gravity and oxygen to dissipate the gunpowder smoke, a large cloud would expand from the barrel.
So, yes, being a Space Shuttle Door Gunner is physically possible and may be needed one day.
The White House on Nov. 4 hit back after former President George H.W. Bush gave his most candid assessment yet of President Donald Trump.
“I don’t like him,” Bush said. His comments were included in a new book by historian Mark Updegrove, called “The Last Republicans,” which focuses on the lives of George H.W. Bush and his son, former President George W. Bush.
“I don’t know much about him, but I know he’s a blowhard,” the elder Bush continued. “And I’m not too excited about him being a leader.”
George W. Bush threw in his own two cents as well.
“This guy doesn’t know what it means to be president,” he said.
A White House official told CNN, in response to the Bushes’ comments, “If one presidential candidate can disassemble a political party, it speaks volumes about how strong a legacy its past two presidents really had.”
“And that begins with the Iraq war, one of the greatest foreign policy mistakes in American history,” the official said.
Trump repeatedly blasted the second Bush administration’s decision to invade Iraq during the 2016 primaries, as he was running against George W.’s younger brother, and George H.W.’s son, Jeb.
“I was totally against the Iraq war,” Trump said at a national-security forum at the height of the presidential race. “You can look at Esquire magazine from ’04. You can look at before that.”
But in a 2002 interview during which shock-jock Howard Stern asked Trump if he supported the invasion, Trump replied, “Yeah, I guess so.”
The White House official added on Nov. 4 that Trump “remains focused on keeping his promises to the American people by bringing back jobs, promoting an ‘America First’ foreign policy and standing up for the forgotten men and women of our great country.”
The George H.W. confirmed in the new book that he voted for Democrat Hillary Clinton in the 2016 election, while George W. says he left his ballot blank.
Prohibition was a master class in unintended consequences, good or bad.
One of those consequences is NASCAR, which is a pretty good time.
Outlawing alcohol may have seemed like a good idea at a time when saloons dominated the streets, booze corrupted politicians, and alcoholism ran rampant — but the the operative phrase here is definitely, “seemed like.” It was not the best idea. It turns out Americans love a drink and will go to great lengths — and speeds — to get it.
Just as with any other business, moonshiners making illegal “white lightning” in the Appalachian Mountains and foothills needed a way to transport their goods to market, and grandpa’s horse cart just wasn’t gonna cut it. They needed vehicles — but not just any vehicle would do.
So, how do you get hooch from the Appalachians to thirsty partygoers in the big city without attracting undue attention? As fast as possible, of course. But there’s more to it than speed: The cars have to look like your average, off-the-line vehicle. They also have to be able to haul as much product as possible. Shiners figured out the way, creating modified vehicles called “stock” cars.
Even after the official end of Prohibition, illegal distillers still needed to move product while evading authorities. They still needed those fast cars.
Bootleggers’ vehicles were fitted with advanced shock-absorption systems to protect the glass jars housing their precious cargo as they sped down mountain roads. They also had the back seats removed to fit more product. Most importantly, they had souped-up engines that allowed them to beat the feds in any race when necessary.
Prohibition ended in 1933, but the American need for speed and love for automobiles that would come to embody the NASCAR spirit lived on.
“The deeper I looked into the whole thing and the more research I did, the more liquor I found. It was just so foundational,” Daniel Pierce, a history professor at the University of North Carolina told NASCAR. “I knew it played a role, but the thing that surprised me was that it was so much a part of the foundation of the sport.”
Even before the end of Prohibition, rum runners and bootleggers would race their souped-up, stripped-down vehicles on the roads and in the backwoods of the American South.
The sport’s anti-establishment roots were very present in NASCAR’s early days. At one of the earliest stock car races at Lakewood Speedway in Atlanta, at least five drivers had liquor law violations on their records. There was an uproar over who should be allowed to drive: “hoodlums” or law-abiding citizens?
In 1947, the sport that would soon become the Monster Energy NASCAR Cup Series was codified by France. The first race held by the National Association for Stock Car Auto Racing was on Jun. 19, 1949. Today, the driving sport’s fans now number in the millions. Their drivers are less outlaw and more law-abiding, driving upwards of 200 miles per hour in some speedways… without attracting attention from the feds.
The first few generations of drivers may have had some liquor law violations on their record, but today’s NASCAR drivers have helped turn a sport of “hoodlums” into a show fit for the whole family.
India is close to finalizing a deal to purchase the S-400 surface-to-air missile system. The S-400, also known as the SA-21 Growler, is an upgraded version of the SA-10 Grumble, and offers longer range. Some versions of this system can hit targets nearly 250 miles away.
India has also recently imported systems from Israel, including a purchase of 131 Barak surface-to-air missile systems, according to a report from Agence France Presse. The report did not state whether the purchase involved the baseline Barak, which has been retro-fitted on to a number of Indian warships, or the newer long-range Barak 8, slated for inclusion on Kolkata- and Visakhapatnam-class guided missile destroyers.
This isn’t the first time Russia and India have worked together — and likely won’t be the last. Currently, the two countries have teamed up to develop a stealth fighter, called the Fifth Generation Fighter Aircraft or Perspective Multi-Role Fighter, based on the Sukhoi Su-57 prototype. India has a history of modifying imported weapons systems, like the SEPECAT Jaguar and the MiG-27 Flogger, making them far more capable than the original. We’ll have to wait and see if they have the same in mind for the SA-21 Growler.

U.S. Army training officials have finalized a plan to ensure new recruits in Basic Combat Training receive more trigger time on their individual weapons.
In the past, new soldiers would learn to shoot their 5.56mm M4 carbines and qualify with the Army’s red-dot close combat optic. Under the new marksmanship training effort, soldiers will qualify on both the backup iron sight and the CCO, as well as firing more rounds in realistic combat scenarios.
“We just want to make sure at the end of the day, they can still pull that weapon out and engage the enemy effectively,” Col. Fernando Guadalupe Jr., commander of Leader Training Brigade at Fort Jackson, South Carolina, told Military.com.
Guadalupe’s brigade, which falls under the Center for Initial Military Training, is responsible for the new training program of instruction for Basic Combat Training that the Army announced early 2018.
The new BCT is designed to instill more discipline and esprit de corps in young soldiers after leaders from around the Army noted trends among soldiers fresh out of training displaying a lack of obedience, poor work ethic and low discipline.
The restructured training program will place increased emphasis on marksmanship training and other combat skills.
Army Chief of Staff Gen. Mark Milley tasked Fort Jackson to lead the effort to toughen standards so soldiers will be more prepared for combat upon completion of BCT, Guadalupe said.

“He wanted us to create the absolute best soldier that we can create coming out of Basic Combat Training prior to their advanced individual training,” he said.
Fort Jackson has been tasked to develop “best practices as we slowly implement the new program of instruction,” Guadalupe said.
The goal is to have initial operating capability by July 15, 2018, and to have the new BCT fully operational at Jackson and the other three BCT centers at Fort Benning, Georgia; Fort Sill, Oklahoma; and Fort Leonard Wood, Missouri, by Oct. 1, 2018, he said.
The redesigned BCT marksmanship program includes more instruction time and requires trainees to spend more time on the range.
In the past, new soldiers in BCT shot 500 rounds and received 83 hours of marksmanship instruction over a 16-day period. The redesigned standards have soldiers shooting 600 rounds and receiving 92 hours of training.
Much of that time will be devoted to shooting and qualifying with front and rear backup iron sights to ensure soldiers become more familiar and more disciplined with their weapons, Guadalupe said.
Trainees start out working in marksmanship simulators, “but the real difference is made when they feel the percussion of that weapon and the effect that it has once actually shooting bullets down range,” he said.
For nearly two decades, soldiers have relied upon sophisticated weapons optics such as the M68 CCO as the primary sight in combat.
But Army senior leaders, for many months now, have been stressing the importance of making sure soldiers can operate in technology-degraded environments since potential enemies such as Russia and China are investing in electronic warfare.
In addition to giving recruits more range time, this new reality is driving the return to learning to shoot with basic iron sights designed to work in any condition.
“While technology is critically important to us, we’ve got to make sure they understand the minimum basics of how you shoot that weapon without any of the technology that you could put on it,” Guadalupe said.

Basic trainees will have to qualify with both iron sights and the CCO as a graduation requirement. For the qualification course, soldiers are still given 40 rounds to engage 40 targets.
But on CCO qualification day, soldiers will run through the course twice to give them more time to become effective with the optic.
“We did that so they would have more range time, more bullets for that CCO,” said Wayne Marken, quality assurance officer at Jackson.
“They spend the predominance of training time on the backup iron sight, and because they complete backup iron sight and then transition to CCO, we have built in extra time for them to get more range time,” he said.
The best qualification score soldiers receive during the CCO record firing day will determine which marksmanship badge they wear — marksman, sharpshooter or expert.
“Let’s say you go out and shoot 37 rounds and you are an expert the first time you qualify,” Guadalupe said. “We are still going to let you go back to the range and shoot again.”
The new emphasis on marksmanship is also designed to expose young soldiers to more realistic shooting scenarios.
At the end of the final field training exercise known as The Forge, soldiers are required to do a battle march and shoot event.
Soldiers march four miles with 40-pound rucksacks and then go immediately into a close-combat firing range, do 25 pushups and engage 40 targets at ranges out to 100 meters with 40 rounds of ammunition.
“This is at the end of The Forge, so the soldiers over a four-day period … have marched over 40 miles already,” said Thriso Hamilton, training specialist for the Basic Combat Training POI.
“The soldiers are extremely tired, they are hungry, they’re under a stressful situation and we want to see at that point how much focus they can garner to be able to … engage targets,” he said.

A New York military aviation researcher got more than she bargained for on a dream trip to a battle-scarred South Pacific island — the chance to help solve the mystery of an American soldier listed as missing in action from World War II.
Donna Esposito, who works at the Empire State Aerosciences Museum in upstate Glenville, visited Guadalcanal in the Solomon Islands this spring and was approached by a local man who knew of WWII dog tags and bones found along a nearby jungle trail. The man asked if Esposito could help find relatives of the man named on the tags: Pfc. Dale W. Ross.
After she returned home, Esposito found that Ross had nieces and nephews still living in Ashland, Oregon. A niece and a nephew accompanied Esposito on her late July return to Guadalcanal, where they were given his dog tags and a bag containing the skeletal remains.
Although it’s not certain yet the remains are the missing soldier’s, the nephew who made the Guadalcanal trip is confident they will be a match.
“It’s Uncle Dale. I have no doubt,” said Dale W. Ross, who was named after his relative.
The elder Ross, a North Dakota native whose family moved to southern Oregon, was the third of four brothers who fought in WWII. Assigned to the Army’s 25th Infantry Division, he was listed as MIA in January 1943, during the final weeks of the Guadalcanal campaign. He was last seen in an area that saw heavy fighting around a Japanese-held hilltop.
When the Japanese evacuated Guadalcanal three weeks later, it was the first major land victory in the Allies’ island-hopping campaign in the Pacific.
Ross’ relatives handed the remains — about four dozen bones, including rib bones — to a team from the Pentagon agency that identifies American MIAs found on foreign battlefields. On August 7, the 75th anniversary of the start of the Battle of Guadalcanal, an American honor guard carried a flag-draped coffin containing the bones onto a US Coast Guard aircraft.
The Pentagon said the remains were taken to Hawaii for DNA testing.
“Until a complete and thorough analysis of the remains is done by our lab, we are unable to comment on the specific case associated to the turnover,” said Maj. Jessie Romero of the Defense POW/MIA Accounting Agency.
The other three Ross brothers made it back home, including the oldest, Charles, who served aboard a Navy PT boat in the Solomons and visited Guadalcanal in the vain attempt to learn about his brother Dale’s fate.
Ross’ niece and nephew made their trip last month with Esposito and Justin Taylan, founder of Pacific Wrecks, a New York-based nonprofit involved in the search for American MIAs from WWII. They met the family whose 8-year-old son found the dog tags and remains. They also were taken to the spot on a slope in the jungle where the discovery was made.
“I never met this man, but I was a little emotional,” Ross, 71, said of the experience.
For Esposito, 45, finding evidence that could solve a lingering mystery in an American family’s military history is the most meaningful thing she’s ever done in her life.
“I can’t believe this has all happened,” she said. “It has been an amazing journey.”
John Newton was not what you’d call a lucky man. One day, he went off to visit some friends in London and was caught up along the way by a press gang – Royal Navy troops sent just to force people into serving aboard the king’s ships. He found himself a midshipman on the HMS Harwich, a position he of course tried to desert immediately. But he was found out, flogged in front of the ship’s company and even attempted suicide.
But the hard luck doesn’t end there. The man who penned the hymn “Amazing Grace” sure lived a life that would inspire such work.
John Newton’s luck was bad even before his impressment. He was practically an orphan; his mother died of tuberculosis when he was six and he was forced to live with a cold, unfeeling relative. After joining the Navy, Newton renounced his faith and plotted to kill his shipmates. He was so difficult to work with, the crew of the Harwich decided to transfer him to the HMS Pegasus en route to India. The Pegasus was a slave trader, but the change in ships did not suit Newton’s temper. The Pegasus decided to leave him in West Africa during one of its slaving missions.
Not quite marooned but not far from it, Newton connected with an actual slaver. He joined the crew of a slave ship and openly challenged the captain by creating catchy songs about him filled with curses and language unlike anything anyone had ever heard. Sailors were known for their foul mouths, but Newton’s was so bad the slaver’s captain almost starved him to death for it.
That’s when a large storm hit their ship.
The storm nearly sunk the ship, but Newton and another crewman tied themselves to the ship’s pumps and began to work for 11 hours to keep it from capsizing. After their miraculous escape, Newton saw the storm as a message from God. He began to work harder, eventually commanding his own slaving ship and sailing between ports in Africa and North America. Eventually, the man collapsed from overwork. He returned to England and never sailed again.
It was in his adopted home of Olney where he wrote a series of autobiographical hymnals, including the well-known “Amazing Grace” as we call it today. In this work, Newton learned how he was a “wretch” due to his participation in the North Atlantic Slave Trade. In life, he set out to help abolish it in England. Newton new connected with William Wilberforce, the British Parliamentarian who led the charge against slavery in Britain and ended it in the Empire in 1807.
Filmed on May 26, 2018, the following footage shows Air Force Lieutenant Colonel Mike Schriever, a pilot in the 303rd Fighter Squadron, flying an A-10 Thunderbolt II alongside his wingman, Air Force 1st Lieutenant Tanner Rindels, over Miami Beach, Florida during the 2nd annual Salute to American Heroes Air and Sea Show, a two-day event showcases military fighter jets and other aircraft and equipment from all branches of the United States military in observance of Memorial Day.
The clip shows the two A-10s maneuvering close to an HC-130 “King” involved in a HAAR (Helicopter Air-to-Air Refueling) mission with two HH-60G Pave Hawks from the 920th Rescue Wing at Patrick Air Force Base in Cocoa Beach, Florida.
VA scientists are working to create a 3D-printed artificial lung that they tout as having the potential to revolutionize the treatment of Veterans affected by lung disease.
One such lung disorder—chronic obstructive pulmonary disease (COPD)—is one of the most prevalent and costliest ailments in the Veteran population.
Dr. Joseph Potkay, a biomedical engineer at the VA Ann Arbor Health Care System in Michigan, is leading the VA-funded research. It calls for making a prototype of the 3D-printed artificial lung. Potkay and his team hope to build what they call the first wearable artificial lung that is compatible with living tissue and is capable of short- and long-term respiratory support.
The lung is seen initially as a temporary measure, a bridge to help patients awaiting a lung transplant or an aid for those whose lungs are healing. Future versions could have longer-term applications, the researchers say.
Potkay says this is the first time high-resolution 3D polymer printing is being used to create microfluidic lungs with three-dimensional blood flow networks.
Potkay’s artificial lung model relies on microfabrication to achieve highly efficient gas exchange and blood paths similar to those in a human lung.

Microfluidic artificial lungs, a new class of artificial lungs, mimic the structure of the natural lung better than conventional artificial lungs. Tiny blood channels, some thinner than a human hair, are closer in shape and dimension to those in a person, allowing for blood flow similar to that in the human body.
The biocompatible coatings on the lung’s surface are equally important. Anytime blood comes in contact with an artificial surface, an immune response leads to hardening of the blood and clotting. Biocompatible coatings will help curtail that immune reaction.
“We hope that these microfluidic flow paths and biocompatible coatings will be more compatible with living tissue, thereby reducing the body’s immune response and increasing the lifetime of the device,” says Potkay, who is also a researcher at the University of Michigan. “The flexibility in design afforded by 3D printing gives us more freedom and thus the ease to build artificial lungs with a small size and pressure drops that are compatible for operation with the body’s natural pressures.”
