No human being has ever experienced anything like going to Mars. The journey would be the longest in human history, and as such, might require some drastic measures in order to be successful.To meet some of the risks, scientists at the European Space Agency (ESA) and the University Hospital of Dresden Technical University in Germany (TUD) have used 3D printing to produce their first bioprinted skin and bone samples. And to prove that the system could work in low-gravity, they did the 3D printing upside down....

Scientists at the Pierre and Marie Curie University have created the world’s smallest mirror, using only 2000 atoms. Their results are published in the journal Physical Review Letters.The team used a very thin optical fiber, combined with a chain of cesium atoms, to create a highly efficient mirror. The team managed to make the mirror so small because they carefully selected the color of the light, and engineered the cesium atoms so they would be in exactly the right places to reflect the light....

There were no small missions for the Tulsamerican, and the Battle of the Bulge was likely its biggest yet. Like 951 other B-24 Liberator bombers, the Tulsamerican had come a long way—the plane had been the very last one to roll off the line at Tusla, Oklahoma, paid for out of the plant worker’s own pockets. On a cloudy day unfit for flight on December 16, the Tulsamerican was sent deep into German territory to bomb fuel refineries near the Polish border, leading a squad of six bombers....

Solar power is rapidly becoming cheaper and more efficient, and not just for utility companies. Many homeowners and businesses are putting solar panels on their rooftops because it’s cheaper in the long run than buying electricity from the grid. But if you’re a large corporation with a tall office skyscraper, there may not be enough roof space to make a difference.For a tall skyscraper, the best place to build solar panels is on the walls, but wall-mounted solar panels would be tricky to install and very expensive....

A flight simulation enthusiast compares footage from Top Gun with that of the flight sim DCS World.DCS World includes both the F-14 Tomcat and the MiG-28 fighter. The game looks incredible. (But of course it’s no match for real jets.)A flight simulation enthusiast has recreated the first two minutes of Top Gun with a high-quality flight simulator. YouTuber Forest Rat took the simulator DCS World and footage from the iconic 1986 film and recreated the flight scenes, staging them side by side....

A dramatic new video shows the moment when a Russian air force fighter jet intercepted a U.S. Air Force spy plane. The video, allegedly taken over the Baltic Sea, is typical of encounters between American and Russian military aircraft and they’re pretty safe, until they aren’t. View full post on YoutubeUploaded to the Russian Ministry of Defense’s YouTube account early this morning, the video shows a Su-27 “Flanker” jet fighter following the contrails of an American RC-135 “Rivet Joint” intelligence gathering aircraft....

Media Platforms Design TeamYou were the person who sold Wi-Fi to Steve Jobs, which essentially changed the way the world communicates. Steve Jobs understood the visionary aspects of Wi-Fi and said that wireless Internet was what he needed to make the Mac laptop special. However, he wanted the Wi-Fi radio to be smaller and less costly. I led the team that successfully achieved those engineering challenges. Once Steve Jobs put Wi-Fi in the laptop, all the other computermakers and gadgetmakers followed behind, jumping on the wireless networking bandwagon....

Electrical problems come fully equipped with more than their fair share of stress–and with good reason. We all know what electricity on the loose is capable of, so utmost caution should be used whenever approaching a repair situation that involves electrical current. But that doesn’t mean that every electrical crisis needs to be left to the pros–especially at the hefty hourly rate a licensed electrician charges. Many small electrical problems can be easily handled by the homeowner equipped with a modest number of specialized tools and a modicum of sense....

A new video shows one of the most fascinating and terrifying weapons in modern military arsenals: the multiple rocket launcher. The video shows a full barrage of nearly 240 artillery rockets launched by Finnish artillerymen, their five-inch rockets training orange flames at night. A second barrage impacts at the edge of a forest, flower-like explosions throwing lethal shrapnel in all directions. It’s one of the most effective examples of the power of artillery ever recorded....

Physicist Markita Landry set up a lab at the University of California, Berkeley to take images of what goes on between cells. She thought that arranging carbon nanotubes around the cells would help her see what was happening inside, but the nanotubes kept puncturing the cell walls. “This was a project that failed pretty hard and pretty quick,” Landry told NPR. But like many scientific flubs, the failure revealed a solution to a completely different problem....

Rain slashes against an unassuming garage in Long Island. I can see bright light shining out from inside. As the garage door slowly opens, VEC9 - a brand new vector-based arcade game - is revealed. Andy Reitano, Michael Dooley, and Todd Bailey stand around the arcade cabinet, their baby, as the game’s hypnotic music pumps out loud in the garage. I step in, I’m immediately offered a beer, and we get to work....

New York has passed the most sweeping law to prevent bird window collisions in the nation.Birds are killed in huge numbers by the large glass surfaces in every U.S. city.The films and decals that prevent bird deaths are inobtrusive and very effective, and New York’s real estate industry supports this law.Crain’s New York reports that New York City has passed legislation requiring all new construction to have bird-friendly glass. New York is the largest U....

The eyes of the world have become fixed on the estimated 50 B61 nuclear bombs stored at Incirlik Air Base in Turkey. As the Turkish military operations in Syria strain relations with the U.S., the security of the bombs has become a potential concern and a certain geopolitical headache. One unidentified senior U.S. official expressed worry to The New York Times that the bombs are being “held hostage” by Turkish President Recep Tayyip Erdogan....

Scientists have found evidence that far more of the ocean is made of “dead zones” without oxygen than they previously believed.They studied the chemical signatures left by anaerobic bacteria to estimate how much carbon is digested in dead zones.Anaerobic bacteria fix carbon without sunlight, a process called dark carbon fixing.In a new study, scientists warn that our estimates of global ocean “dead zones” may be woefully low because of misleading biofeedback in the form of dark carbon....

Last year, astronomers thought they had discovered a bizarre new galaxy that threatened to challenge the basic principles of physics. Turns out not so much.Now, the galaxy that scientists believed to contain no dark matter is looking much more normal. Scientists believe the whole thing was a miscalculation.The questions first popped up in 2018 when scientists announced the discovery of a galaxy known as NGC1052-DF2 (DF2 for short).“We thought that every galaxy had dark matter and that dark matter is how a galaxy begins,” said Pieter van Dokkum of Yale University in New Haven, Connecticut, lead researcher of the Hubble observations, in a NASA press statement at the time....

GREENVILLE, South Carolina – It’s mid-October and the leaves here are already turning to various shades of red and gold. And thanks to the driving rain that’s been falling since last night, many of those leaves are scattered across the twisting, narrow roads that lead out of town. Those that aren’t yet sticking to the macadam are blowing across the road, compliments of the raw, 50-degree winds. In other words, it’s a beautiful day to sit inside, gazing into a crackling fireplace sipping any one of several different warming liquids that come to mind....

Daryl SmithNew Haven, Conn.Age: 48Years on Job: 23 Daryl Smith didn’t set out to custom-build radiation detectors. After choosing glass blowing over graduate school, he spent years working for pharmaceutical and chemical companies; becoming a glass blower at Yale University allowed him to use his old-fashioned craft to create state-of-the-art scientific tools. Now he gets all sorts of requests: alterations to standard equipment, designs for prototypes, even glass rods for a detector that went into CERN’s Large Hadron Collider in Europe....

Scientists studying two small arms of the Milky Way discovered a stunning new formation. While they’ve seen similar dust and gas shapes, never at this size.The new formations, called Giant Elephant’s Trunks, could help create stars and planets.Here’s a remarkable sight: towers of molecular gas in star-forming complexes known as the Giant Elephant’s Trunks. With the Nobeyama 45-meter Radio Telescope in Nagano, Japan, astronomer Yoshiaki Sofue of the University of Tokyo recently conducted a survey of the plane of our Milky Way galaxy....

For decades, we used chemicals called clorofluorocarbons (CFCs) in aerosol cans and refridgerators, unaware of the effect they had on the environment. In the 1970s, scientists began to realize that the CFCs we’d been releasing into the atmosphere were staying there, slowly eroding the ozone layer that protects us from harmful ultraviolet rays. In response, the world’s nations signed the Montreal Protocol in 1987, which slowly phased out CFCs over the subsequent two decades....

Snoopy, the 50-year-old NASA lunar module that helped with the first Moon landing during the Apollo 10 mission, may have been found by an amateur team of astronomers.Nick Howes, a member of the team, says he is “98 percent convinced” that their finding is the long lost Snoopy module, which was shot into orbit (without being tracked) in 1969.Howes suggests that once it’s confirmed the module is indeed Snoopy, Elon Musk should use a SpaceX aircraft to retrieve it....
