An innovative new combustion engine eliminates half the guts of a traditional engine, and uses a fascinating internally-rotating piston and sleeve arrangement, making it lighter, simpler and more efficient while still making strong power and torque. Michael Arsenaeu designed the Avadi engine 20 years ago in the hopes of creating an entirely new engine design to be efficient as well as reduce emissions. In 2015, Avadi began the build and development. Rotary might be a good name for this sort of engine, if the name wasn't already taken. Everything inside the crankcase rotates, but unlike a Wankel-style rotary engine, this...

Destined for delays. Avid travelers tend to opt out of checked bags to avoid delayed baggage arrival, difficulty picking out their items or fear of their bag not reaching their destination. But for those who have no choice, they’ll add a personal marker on the suitcase in anticipation of making their baggage pickup smoother. However, this age-old luggage hack is delaying your bags from arriving on the baggage carousel. Travelers have developed a habit of attaching a colorful ribbon, luggage tag or other accessories to make their suitcases stand apart from the hundreds of bags in the rotation. Dublin Airport...

The U.S. Air Force is facing a lawsuit over claims it refused to release documents related to its transgender program.

For both military and civilian applications, launching satellites into orbit has long been both useful and incredibly expensive. But over the last decade, the costs to put payload into orbit have shrunk dramatically, driven by launchers like the SpaceX Falcon 9 & Falcon Heavy while the number of satellites in orbit has exploded. And now, with tests proceeding with the two-stage Starship super-heavy, it may be that even cheaper access to space is on the horizon. In this episode we explore why demand for orbital assets is increasing, how the US retook top spot in the Space Race, and what...

Diabetics sick of daily injections may have renewed hope for a less invasive alternative. Scientists at the University of British Columbia (UBC) have developed a new delivery method for insulin where users just place a few drops under their tongue. A hallmark of diabetes is the inability to produce enough insulin to regulate blood glucose levels. Those with type 1, and many with type 2, will need insulin a few times a day, and that’s usually delivered through a subcutaneous injection. Not only is that uncomfortable, but it can be hard for patients to stick to, and creates potential biohazard...

Photo by Jin Liwang/EPA-EFE June 2 (UPI) -- After a month-long journey, a Chinese spacecraft has landed on the far side of the moon, the China National Space Administration said. Chinese space administration officials have said they intend to collect rock and soil from this notoriously difficult-to-reach region of the lunar surface for the first time in history, the CNSA said. "Everyone is very excited that we might...

A team of scientists has created an ultra-thin coating that can provide high-efficiency night vision to any glass surface, including ordinary reading glasses. Designed using something called a non-local metasurface, the plastic-wrap-thin coating also lets through all of the visible light, allowing users to see perfectly during daytime or at night. Some previous efforts using a non-local metasurface to create a night vision coating have shown limited success. However, those efforts have suffered from severely limited image quality. The inventors of this newest coating say they have broken through that barrier, resulting in a high-definition image visible light image that...

"I love Tiny! One of my favorite mentors ever and one of the most talented chefs in the Army. Tell him he's looking a little small."That was D.C.-area event producer Stephen Ball's reaction on Twitter to a photo snapped by CNN White House reporter Kate Bennett. Bennet captured two chefs tending an outdoor grill for the White House's Iftar celebration, a breaking of the Ramadan fast. And the Internet went wild.

“War is a monster that is constantly hungry, it must be fed, and I see that the Americans and the Democratic government of the United States, and the leaders of the European Union, are ready to feed it.”In his recent appearance on Hungarian state radio, Prime Minister Viktor Orbán delivered a powerful critique of Western European leaders and NATO’s actions, which he sees as dangerously escalating the conflict between Ukraine and Russia. Orbán emphasized Hungary’s unwavering stance of non-participation in the war, firmly rejecting the idea of shedding Hungarian blood for Ukraine.NATO’s Escalation and MilitarizationOrbán criticized Western European leaders for...

While excavating a cemetery for medieval knights in Spain, archaeologists came across something unexpected: the remains of a woman. Pierced by sharp objects, her bones suggest she fought and died in battle, likely over 800 years ago. The discovery prompted a flurry of questions about her role in the male-dominated society. Who was she? Why was she buried there? Did she fight alongside the knights? By analyzing her skeleton, archaeologists shed light on her diet, lifestyle and status, allowing them to venture several hypotheses about her identity, according to a study published May 14 in the journal Scientific Reports.

Nathan Baskind was killed in action shortly after D-Day. A year-long investigation found his remains and ensured his reinterment under a Star of DavidBy Andrew Lapin June 6, 2024 Growing up, Samantha Baskind’s father would sometimes mention his “Uncle Nate,” who stormed the beaches of Normandy on D-Day. He called Nate “a great Jewish American war hero,” often just around Memorial Day, Baskind recalled. “He would always use that exact same phrase.” There’s a family picture of Nate in his mid-twenties, just before shipping off to war, holding Baskind’s father as a toddler. But the family knew nothing of his...

When astronomers turn our radio telescopes out towards space, we sometimes detect sporadic bursts of radio waves originating from across the vast expanse of the universe. We call them “radio transients”: some erupt only once, never to be seen again, and others flicker on and off in predictable patterns. We think most radio transients come from rotating neutron stars known as pulsars, which emit regular flashes of radio waves, like cosmic lighthouses. Typically, these neutron stars spin at incredible speeds, taking mere seconds or even a fraction of a second to complete each rotation. Recently, we discovered a radio transient...

In a pioneering study, a team of researchers from Massachusetts General Hospital and Boston Children’s Hospital have identified a brain network essential for human consciousness. Aided by advances in ultrahigh-resolution magnetic resonance imaging (MRI) technology, researchers discovered previously unknown pathways connecting various brain regions, forming what they termed the “default ascending arousal network” (DAAN). In findings published in Science Translational Medicine, researchers propose that this brain network plays a pivotal role in maintaining wakefulness and integrating arousal with awareness in the resting human brain. The discovery could be a significant breakthrough in understanding a range of neurological disorders while shedding...

Greeks fought on the side of the Allies on D-Day, June 6, 1944, which was the largest seaborne invasion in history. The operation began the liberation of France (and later western Europe) and laid the foundations of the Allied victory on the Western Front. Eddie Lambros was one of the 155 Greek soldiers who landed on Normandy Beach the day World War II took a turn. It was a day which would eventually lead to the end of European Nazi occupation.

I post this story once a year, usually on June 6 or on Veterans Day. I’m putting the story in the Comment box because I’m not sure of the formatting here. If anyone has a similar story, please share it.

Jared Isaacman @rookisaacman · 4h Unreal SpaceX team.. great job. You just brought the most powerful booster in the world one step closer to reusability.

How low will he go to dishonor the veterans?

The majority of Americans are simply hard working folks who live by the rule of “mind your own business.”

The Airbus Wingman concept Bringing some flash to military aviation, Airbus is showing off its Wingman drone concept this week at the International Aerospace Exhibition (ILA) in Berlin. The 1:1 scale mock-up is the aerospace equivalent of a "show car" for highlighting ideas. Trade shows like the ILA that runs through June 9 are not only an opportunity for salespeople to fatten up their order books, they're also a chance for companies to give potential customers an exclusive look at future products before the general public gets to know about them. Not only that, these sneak peaks allow engineers to...
