Humans, Neanderthals share up to 98.5 percent DNA, new study reveals
LinkedIn
Many humans DNA carry genes from Neanderthals, a legacy of past admixture

You’re not much different than a Neanderthal, according to your DNA. At least according to a new study published by Science Advances. The journal found that as little as 1.5 percent of our DNA is unique to modern humans, and not shared with our ancestral species.

“That’s a pretty small percentage,” Nathan Schaefer, a University of California scholar and co-author of the report, told The Associated Press. “This kind of finding is why scientists are turning away from thinking that we human are so vastly different from Neanderthals.”

The study compared modern human DNA to that extracted from the fossilized remains of extinct Neanderthals and Denisovans, two pre-human species that died off 35,000 and 50,000 years ago, respectively. Both species are believed to have bred with early humans.

“Many humans carry genes from Neanderthals, a legacy of past admixture,” the study states. “We find that only 1.5 to 7 percent of the modern human genome is uniquely human.”

It Was His Day Off. Then the Space Station Went for a Spin.
LinkedIn
A new Russian module, named Nauka, suddenly fired its thrusters after docking at the International Space Station on Thursday.

The International Space Station, with a mass of more than 900,000 pounds and spanning an area as large as a football field, is not designed to do back flips like an Olympic gymnast.

But when a newly attached Russian compartment suddenly fired its thrusters on Thursday, NASA said on Twitter that the station tipped by 45 degrees. Actually, it was much more than 45 degrees. “That’s been a little incorrectly reported,” said Zebulon Scoville, the flight director who was in charge at NASA’s mission control center in Houston during Thursday’s tumbling incident. In an interview, Mr. Scoville described how the International Space Station spun one-and-a-half revolutions — about 540 degrees — before coming to a stop upside down. The space station then did a 180-degree forward flip to get back to its original orientation.

The seven astronauts aboard were never in danger, Mr. Scoville said, and the situation did not spiral out of control. Still, in seven years as a NASA flight director, this was the first time that Mr. Scoville had declared a “spacecraft emergency.”

Mr. Scoville was not even scheduled to work on Thursday. Another flight director, Gregory Whitney, led the operations on NASA’s side during the docking of the 23-ton Russian module named Nauka — “science” in Russian.

But Mr. Scoville had led earlier preparations for Nauka’s arrival, and he was curious. “So I decided to put on a tie and just go and watch it from the viewing gallery behind the control room,” he said. “And I was there with Holly Ridings, who’s the chief flight director, and Reid Wiseman, the chief of the astronaut office.”

After the docking, Mr. Whitney had some meetings to attend, so Ms. Ridings asked Mr. Scoville to take over the second half of Mr. Whitney’s shift. “And I’m like, ‘I’d be happy to. The docking — the hard part — is over. Let me go get a handover from him,’” Mr. Scoville said. “And so kind of impromptu, I went in and took the shift from him. He unplugged, I plugged in, and I turned around, and the caution warning board lit up.”

It was 11:34 a.m. Houston time.

“We had two messages — just two lines of code — saying that something was wrong,” Mr. Scoville said.

The messages said the space station had lost “attitude control” — that is, it had begun to tip. Usually, four large, heavy gyroscopes spinning at 6,000 revolutions a minute keep the space station steady, but some force appeared to be overpowering them.

“And so at first I was like, ‘Oh, is this a false indication?’” Mr. Scoville said. “And then I looked up at the video monitors and saw all the ice and thruster firings. This is no kidding. A real event. So let’s get to it. You get about half a breath of ‘Oh, geez, what now?’ and then you kind of push that down and just work the problem.”

Nauka’s thrusters had started firing, trying to pull away from a space station it was securely docked to.

Worse, there was no way to turn them off.

His counterparts at the mission control in Russia told him that Nauka was configured so that it could receive commands directly only from a ground station in Russia. The next pass over Russia was 70 minutes away.

The new Russian module is docked on the underside of the space station. When Nauka tried to move, it pulled down the rear of the space station, and the front pitched upward. “It’s exactly like doing a back flip,” Mr. Scoville said.

The rate of rotation reached a maximum of 0.56 degrees a second, Mr. Scoville said. That spinning is not nearly fast enough to generate significant artificial gravity — he said the astronauts reported almost no noticeable change in conditions within the station.

However, a spinning space station imparts stresses on the structure, and antennas are no longer pointing where they are supposed to. Mission controllers quickly informed the astronauts what was going on and gave them instructions.

“We knew we had a limited amount of time,” Mr. Scoville said.

Declaring a spacecraft emergency activated additional antennas in the United States that could communicate with the space station. But still, the connection between the ground and space was lost twice, once for four minutes, the other time for seven minutes.

Commands from the ground stowed and locked the station’s solar arrays. The astronauts took care of locking down the radiators, which emit heat from the station to space.

Google’s time crystal discovery is so big, we can’t fully comprehend it
LinkedIn
Google corporate office. Google recently found time crystals that can change the computer world

By , BGR

Forget Google Search and Fuchsia. Researchers from Google, Stanford, Princeton, and other universities might have made a computer discovery so big we can’t fully comprehend it yet. Even Google researchers aren’t entirely sure that their time crystal discovery is valid. But if it turns out to be accurate, then Google might be one of the first companies to give the world a crucial technological advancement for the future. Time crystals will be an essential building block in quantum computers, the kind of computers that can solve complex problems with incredible speed and power technologies that aren’t even invented.

What is a quantum computer?
Google isn’t the only company building quantum computers, and these types of machines keep popping up in the news with regularity. Quantum computers won’t reach your phone, and they’re not going to play games. Even if they did, Nintendo will totally ignore the latest computer technology when designing future consoles.

As The Next Web explains, we plan on using quantum computers for challenging problems. Examples include warp drives that could make fast interstellar travel possible. And medical technology that could cure virtually any disease.

But quantum computers are really hard to build, maintain, and even use. That’s where Google’s time crystals might come into play. As it stands now, quantum computers feature qubits, computer bits in the quantum world. These qubits act differently when someone observes them than when they’re left alone. That’s what makes it difficult to measure qubit states. And that instability makes using a quantum computer problematic. That’s where time crystals come in.

Google’s time crystals
Theorized in 2012, the time crystal concept is a new phase of matter. The Next Web explains that time crystals contradict one of Sir Isaac Newton’s famous laws. The first law of motion says that “an object at rest tends to stay at rest and an object in motion tends to stay in motion.”

In our universe, there’s something called high entropy (disorder). Something always happens thanks to energy exchanges. Entropy remains the same if there are no processes but increases in their presence. But that’s not valid for time crystals. They can maintain entropy even when they’re used in a process.

To understand Google’s time crystals, The Next Web offers a great analogy with snowflakes. They have unique designs, as the atoms are arranged in specific ways. Snow falls, melts, water evaporates, and then it’ll eventually become snow again. All these processes involve energy exchanges. A time crystal would be like having a snowflake that can change between two configurations back and forth with no energy usage or energy loss. Time crystals can have their cake and eat it too, and they can do it perpetually.

Animals Emerged 350 Million Years Earlier Than Previously Thought, Fossil Discovery Suggests
LinkedIn
A fragment of the spongin skeleton from a modern keratose sponge—literally a bath sponge from Greece.

By George Dvorsky, Gizmodo

Ancient rocks from northwestern Canada have been found to contain structures consistent with sea sponges. At 890 million years old, they could be the oldest known animal fossils on Earth.

Simple, single-celled life forms first appeared on Earth about 3.4 billion years ago, but it took a while for more complex animal life to emerge. The Cambrian Explosion of complex lifeforms happened around 540 million years ago, which coincides with the oldest undisputed sponge fossils on record.

In 2018, the discovery of steroids—a known biomarker—in rocks dated to between 660 million and 635 million years ago pushed the emergence of sponges to the Neoproterozoic, which is at least 100 million years before the Cambrian. Genetic analyses of modern sponges likewise suggests an early origin for these sea creatures, further reinforcing the notion that sponges were the first animals to appear on Earth.

Paco Cardenas, a biologist at Uppsala University in Sweden who wasn’t involved in the new study but is an expert on sponges, said this discrepancy between the fossil record and the chemical and DNA evidence “has been highly debated these past years.” Hence the importance of the newly reported discovery, which has implications for how we understand the origin of all animal life on Earth.

Elizabeth Turner from Laurentian University in Sudbury, Canada, is the sole author of the new Nature paper, and she reports on the discovery of fossil-like structures found in rocks pulled from the 890-million-year-old Little Dal reefs in the Stone Knife Formation of Canada’s Northwest Territories.

“If these fossils are confirmed to be sponge fossils, they would definitely be the first fossils of animals in the fossil record, thus pushing back the emergence of animals to 350 million years before the Cambrian,” Cardenas explained in an email. This recent discovery “may finally reconcile those [previous] lines of evidence,” but it “also raises new questions,” he added.

Peering at the rocks with a microscope, Turner noticed tube-shaped structures covered by mineral calcite crystals. These features bore a striking resemblance to the fibrous skeletons of horny sponges, and they formed from the decay of these ancient creatures, she argues. Horny sponges are still around today, and you might even be using one as a bath sponge (so yeah, humans might actually be descended from bath sponges, and as a dedicated fan of Spongebob Squarepants, I’m actually very cool with that).

Turner was able to rule out other interpretations of the microstructures owing to the configuration of the fossil material.

“It consists of little tubes that branch divergently and then rejoin to form a complex, three-dimensional meshwork,” she said in an email. “Of the branching organisms that could be considered as alternative interpretations, none of them have that kind of three-dimensional meshwork—not true algae, not bacteria, and not fungi.”

50 Years Ago, NASA Put a Car on the Moon
LinkedIn
The lunar rovers of Apollo 15, 16 and 17 parked American automotive culture on the lunar surface, and expanded the scientific range of the missions’ astronaut explorers.

By Rebecca Boyle, New York Times

Dave Scott was not about to pass by an interesting rock without stopping. It was July 31, 1971, and he and Jim Irwin, his fellow Apollo 15 astronaut, were the first people to drive on the moon. After a 6-hour inaugural jaunt in the new lunar rover, the two were heading back to their lander, the Falcon, when Mr. Scott made an unscheduled pit stop.

West of a crater called Rhysling, Mr. Scott scrambled out of the rover and quickly picked up a black lava rock, full of holes formed by escaping gas. Mr. Scott and Mr. Irwin had been trained in geology and knew the specimen, a vesicular rock, would be valuable to scientists on Earth. They also knew that if they asked for permission to stop and get it, clock-watching mission managers would say no. So Mr. Scott made up a story that they stopped the rover because he was fidgeting with his seatbelt. The sample was discovered when the astronauts returned to Earth, Mr. Scott described what he’d done, and “Seatbelt Rock” became one of the most prized geologic finds from Apollo 15.

Like many lunar samples returned to Earth by the final Apollo missions, Seatbelt Rock never would have been collected if the astronauts had not brought a car with them. Apollo 11 and Apollo 13 are the NASA lunar missions that tend to be remembered most vividly. But at the 50th anniversary of Apollo 15, which launched on July 26, 1971, some space enthusiasts, historians and authors are giving the lunar rover its due as one of the most enduring symbols of the American moon exploration program.

Foldable, durable, battery-powered and built by Boeing and General Motors, the vehicle is seen by some as making the last three missions into the crowning achievement of the Apollo era.

“Every mission in the crewed space program, dating back to Alan Shepard’s first flight, had been laying the groundwork for the last three Apollo missions,” said Earl Swift, author of a new book about the lunar rover, “Across the Airless Wilds: The Lunar Rover and the Triumph of the Final Moon Landings.”

“You see NASA take all of that collected wisdom, gleaned over the previous decade in space, and apply it,” Mr. Swift said. “It’s a much more swashbuckling kind of science.”

Once Neil Armstrong’s small step satisfied Project Apollo’s geopolitical goals, NASA emphasized science, said Teasel Muir-Harmony, curator of the Apollo collections at the Smithsonian Institution’s National Air and Space Museum in Washington. While the first moon-walkers retrieved samples near their landing sites, scientists had long hoped for a lunar road trip that promised rare rocks. Plans for a lunar rover were finally given the green light just two months before Armstrong and Buzz Aldrin became the first humans on the moon.

Though moon buggies had been imagined for years, driving a car on the moon is more complicated than it sounds. Throughout the 1960s, engineers studied a variety of concepts: tank-like tracked vehicles, flying cars, even a rotund monstrosity shaped, as Mr. Swift describes it, “like an overgrown Tootsie Pop, with its spherical cabin up top of a single long leg, which in turn was mounted on a caterpillar-tread foot.” Ultimately, a carlike buggy came out on top.

“There were other outlandish ideas, like a pogo stick, or a motorcycle — things that I am glad they didn’t pursue,” Dr. Muir-Harmony said. “The lunar rover is, in some ways, relatively practical.”

The moon car was also quintessentially American. The rover’s exposed chassis, umbrella-like antenna and wire wheels meant it looked like no car on Earth, yet its connection to the American auto industry and the nation’s love affair with the automobile captivated public attention like nothing since Apollo 11, Dr. Muir-Harmony said.

Starting with Project Mercury in the 1960s, a Florida car dealer allowed astronauts to lease Chevrolet cars for $1, which were later sold to the public. The Apollo 15 crew chose red, white and blue Corvettes. A photo spread in Life magazine showed the astronauts posing with their iconic American muscle cars alongside the moon buggy, making the lunar rover look cool by association, Dr. Muir-Harmony said. “There’s a lot to unpack in that picture,” she added.

Scientists Are Using a Balloon to Launch a Telescope
LinkedIn
An image of the Rotten Egg Nebula captured by the Hubble Space Telescope and released by NASA in August 2001.

By Jake Dean, Slate

Exploring space requires scientists to get a little creative. One of my professors at Arizona State University once proposed a mission to smash a copper ball into Mars to examine the ejecta and subsurface of the planet. (ASU is a partner with Slate and New America in Future Tense.) Sometimes, the simplest and cheapest solutions are best in a field where high-tech offerings can pose a significant chance of failure.

Cheap solutions like, say, launching a telescope via a stadium-sized high-tech helium balloon instead of a rocket. That’s the idea behind the Super-Pressure Balloon-borne Imaging Telescope—or SuperBIT, which is expected to make its operational debut in April 2022. On June 21, at the Royal Astronomical Society’s annual National Astronomy Meeting, the team (consisting of scientists from NASA, the Canadian Space Agency, and universities in Canada, the U.S., and England) shared results from testing. This balloon will soon provide telescope imagery to rival (and possibly surpass) that of the Hubble Space Telescope—along with reducing the backlog of imagery requests. As useful as Hubble is, it simply can’t meet the demand of every scientist who wants to task it for a scientific query. It is just one telescope, after all.

So, this telescope isn’t exactly going to space; it will work at an altitude of roughly 25 miles above the surface, according to a Royal Astronomical Society press release. That’s above 99.5 percent of Earth’s atmosphere—so, as you may have recently learned from Bezos and Branson’s childish spat, it’s technically not in space. But unlike Bezos and Branson, it’s actually going to produce useful science. This balloon setup will get the telescope above the atmospheric interference that is critical to ensure good imagery. The atmosphere protects Earth from the harmful effects of various electromagnetic radiation, but it can also blur the images telescopes capture.

Now you may be wondering: How long will this helium balloon stay aloft? We’ve all seen birthday balloons slowly drop to the floor after a few days of clinging to our ceiling. Well, that’s where NASA’s ingenuity comes in. The super-pressure balloon maintains enough internal pressure to stay aloft day or night and should stay airborne for weeks, possibly even months if it needs to. This is quite an improvement when compared with NASA’s past attempt at this design: In late 2014 it planned to keep an Antarctic telescope aloft for 100 days. But the balloon quickly sprung a leak and was forced to land just two days into the mission.

So, given the technical issues NASA has faced in the past, why use a balloon? Three key reasons. First, the cost. The construction and operation budget for the SuperBIT’s first telescope was roughly $5 million, which is insanely cheap by space standards. For context, the Royal Astronomical Society estimated that this is .1 percent of the cost of a similar satellite mission. Second, the ability to bring the balloon back to the surface for repairs and upgrades makes this telescope system uniquely flexible. Given this, the SuperBIT setup isn’t married to one set of hardware forever once launched. As Mohamed Shaaban, a Ph.D. student at the University of Toronto and a central member of the project, explained for Space.com, “SuperBIT can be continually reconfigured and upgraded.” When Hubble becomes obsolete, well, Hubble is no longer useful. And as we recently learned, it’s quite a bother to repair its 1980s technology when it breaks. If a telescope aboard SuperBIT becomes obsolete or runs into technical issues, you just bring the balloon back to the surface and put a new telescope on it. Finally, the use of balloon removes the necessity of burning rocket fuel to launch a telescope. (Rocket fuel is predictably terrible for the environment.)

NASA predicts a “wobble” in the moon’s orbit may lead to record flooding on Earth
LinkedIn
moon in space

By Sophie Lewis, CBS News

Every coast in the U.S. is facing rapidly increasing high tide floods thanks to a “wobble” in the moon’s orbit working in tandem with climate change-fueled rising sea levels. A new study from NASA and the University of Hawaii, published recently in the journal Nature Climate Change, warns that upcoming changes in the moon’s orbit could lead to record flooding on Earth in the next decade. Through mapping the National Oceanic and Atmospheric Administration’s (NOAA) sea-level rise scenarios, flooding thresholds and astronomical cycles, researchers found flooding in American coastal cities could be several multiples worse in the 2030s, when the next moon “wobble” is expected to begin. They expect the flooding to significantly damage infrastructure and displace communities.

While the study highlights the dire situation facing coastal cities, the lunar wobble is actually a natural occurrence, first reported in 1728. The moon’s orbit is responsible for periods of both higher and lower tides about every 18.6 years, and they aren’t dangerous in their own right.

“In half of the Moon’s 18.6-year cycle, Earth’s regular daily tides are suppressed: High tides are lower than normal, and low tides are higher than normal,” NASA explains. “In the other half of the cycle, tides are amplified: High tides get higher, and low tides get lower. Global sea-level rise pushes high tides in only one direction – higher. So half of the 18.6-year lunar cycle counteracts the effect of sea-level rise on high tides, and the other half increases the effect.”

But this time around, scientists are more concerned. With sea-level rise due to climate change, the next high tide floods are expected to be more intense and more frequent than ever before, exacerbating already grim predictions.

In 2019, NOAA reported more than 600 such floods. Scientists expect three to four times that amount in the mid-2030s, after sea-level rise has another decade to progress.

According to the study, these floods will exceed flooding thresholds around the country more often, and can also occur in clusters lasting more than a month, depending on the positions of the moon, Earth and sun. During certain alignments, floods could happen as frequently as every day or every other day.

“Low-lying areas near sea level are increasingly at risk and suffering due to the increased flooding, and it will only get worse,” said NASA Administrator Bill Nelson. “The combination of the Moon’s gravitational pull, rising sea levels, and climate change will continue to exacerbate coastal flooding on our coastlines and across the world.”

NASA is actively searching for intelligent life in the universe and is looking for habitable planets, official says

Image of the Milky Way Galaxy without intelligent life

By Emily DeCiccio, CNBC

Intelligent life may exist elsewhere in the universe besides Earth, NASA Administrator Bill Nelson said in an interview Tuesday, and NASA is actively searching for signs. “If you have a universe that is 13.5 billion years old — it is so big — is there another chance for another Sun and another planet that has an atmosphere like ours? I would say yes, so I think we’re going to get some indication that there’s intelligent life out there,” said Nelson during an interview Tuesday.

In a report on unidentified flying objects released June 25, the U.S. government couldn’t explain 143 of the 144 cases of UFOs reported by military planes from 2004 to 2021, according to the Office of the Director of National Intelligence.

Nelson told CNBC’s “The News with Shepard Smith” that NASA has been involved in searching for intelligent life for years, and noted that the agency is looking for life on the planets in our solar system and elsewhere in the cosmos to determine other Suns that have planets with a habitable atmosphere.

The former Florida Senator added that part of the search includes learning more about Mars. NASA’s experimental helicopter Ingenuity made its ninth flight on Mars on Monday. Ingenuity flew for nearly 3 minutes, going as fast as 5 meters (over 16 feet) per second, according to a tweet from NASA’s Jet Propulsion Laboratory in California.

“This particular time, it’s scouting a very sandy region in order to determine should the rover go there and possibly get stuck in the sand, so Ingenuity is just doing amazing things,” Nelson said.

NASA described Ingenuity’s latest flight as “the most nerve-wracking flight since Flight 1.”

Beautiful Bone Carving From 51,000 Years Ago Is Changing Our View of Neanderthals
LinkedIn
Neanderthals bone Carving From 51,000 Years Ago

By CONOR FEEHLY, Science Alert

As humans, we like to think we have some pretty unique traits in the animal kingdom. Language enables us to communicate efficiently with one another. Culture preserves and accumulates knowledge through generations. Technology and tools help us solve problems. Symbols and art reveal clues about our complex experiences. A growing body of evidence suggests the traits we tend to assume are unique to modern humans, may once have been present in our hominin cousins, too.

Scientists have now announced the discovery of a 51,000-year-old engraved giant deer bone which was produced by Neanderthals in the Harz Mountains, now northern Germany. The carvings on the deer bone are precisely and artistically arranged into chevron patterns. Previous evidence of symbolic and artistic traits in Neanderthals has been scarce, but the new findings raise exciting questions about how complex Neanderthal behavior might truly have been.

The findings add to previous research already pointing to Neanderthals having complex behavioral traits, such as their capacity to produce and hear the speech sounds of modern humans, their production of tools and technology, and their mourning of the dead. Archaeologists Dirk Leder, Thomas Terberger and their colleagues carbon dated the deer bone, placing it at 51,000 years old. Microscopic analysis and experimental replication suggests the bone was actually boiled to soften before the engraving took place.

Up until now, Neanderthal artistic evidence amounted to minimalistic motifs and hand stencils on cave walls at three Spanish sites – La Pasiega, Maltravieso, and Ardales.

The authors of the new study believe the engraving of individual lines in the chevron design combined with the fact that these giant deer (Megaloceros giganteus) were rare north of the alps at that time, strengthens the idea that the engravings have symbolic meaning and show evidence for conceptual imagination in Neanderthals.

“Archaeological finds of artist engravings are rare and, in some cases, ambiguous. Evidence of artistic decorations would suggest production or modification of objects for symbolic reasons beyond mere functionality, adding a new dimension to the complex cognitive capability of Neanderthals,” writes Silvia Bello from the Natural History Museum in London, in an accompanying News & Views article published in Nature.

“The choice of material, its preparation before carving and the skillful technique used for the engraving are all indicative of sophisticated expertise and great ability in bone working,” adds Bello.

A question at the heart of this research is whether these Neanderthals were influenced by ancient H. sapiens contemporaries in the production of this type of carved bone.

Leder, who works at the State Service for Cultural Heritage Lower Saxony, and colleagues believe that Neanderthals had the manual and intellectual capabilities to produce the artifact independently of any modern human influence.

They support their hypothesis with archaeological evidence that suggests H. sapiens arrived in Central Europe several millennia after the engraved bone was dated.

Flying car with BMW engine completes 1st inter-city test flight

By Kelly Hayes, Fox 11 Los Angeles

A prototype flying car completed a 35-minute flight this week between international airports in Slovakia, fulfilling what developers called “a key milestone” in moving toward production. The dual-mode car-aircraft, called AirCar, flew on Monday between international airports in Nitra and Bratislava. It was AirCar’s first inter-city flight and 142nd successful landing, according to Klein Vision, the company behind its development.

It takes less than three minutes to transform from a road vehicle into an aircraft — and vice versa. Upon landing, a video shows the aircraft’s narrow wings fold down along the sides of the car and become ready for the roadway.

“The automated transition from road vehicle into an air vehicle and vice versa, deploying/retracting wings and tail is not only the result of pioneering enthusiasm, innovative spirit and courage; it is an outcome of excellent engineering and professional knowledge,” Dr. Branko Sarh, Boeing Co. Senior Technical Fellow, said in a statement.

The AirCar’s first prototype is equipped with a BMW engine with a fixed-propeller and ballistic parachute.

The hybrid car-aircraft has logged more than 40 hours of test flights, including steep 45 degree turns and stability and maneuverability testing, the company said.

It has flown at a height of 8,200 feet with a range of about 600 miles (1,000 km), according to Klein Vision.

The prototype was the decades-long dream of Professor Stefan Klein, who “devoted the last twenty years converting his flying-car dream into reality.” The AirCar model took about two years to develop and cost “less than 2 million euros” to develop, the company told the BBC.

Klein Vision sees the flying car as having a “huge market,” with a goal of attracting even a small percentage of the global airline and taxi sales.

“There are about 40,000 orders of aircraft in the United States alone,” Anton Zajac, Klein Vision’s co-founder, investor and pilot, told the BBC. “And if we convert 5% of those, to change the aircraft for the flying car – we have a huge market.”

Klein Vision said the second AirCar prototype, the pre-production model, would be equipped with a 300 horsepower engine and receive the EASA CS-23 aircraft certification with an M1 road permit.

Astronomers Think They’ve Spotted a Rare Kind of Supernova Only Predicted to Exist
LinkedIn

A team of astronomers discovered a supernova they believe was formed after the star’s electrons were consumed by other elements in its core. That would make the supernova an electron-capture supernova, a theorized type of stellar explosion first proposed 40 years ago. This may not be the first of these rare explosions documented by humans, though: The famous supernova recorded by Chinese astronomers on July 4, 1054 may also have been an electron-capture supernova, the researchers say.

Supernovae are the brilliant aftermaths of star death, and we only observe two types. If this latest observation is correct, it will be the first time a third type has been documented. The two well-known types of supernovae are type Ia, when a small, cool, and very dense star orbiting another star reaches the end of its life and explodes, and type II, when a massive star runs out of fuel and collapses in on itself. The research team described a recent supernova, SN 2018zd, in a paper published today in Nature Astronomy, and said its conditions sit between the two previously known types of supernovae, making it the theorized third type.

The star was just the right size—not too big or small—to produce this kind of explosion. “The mass is not light enough to lose the outer envelope and leave a white dwarf, or heavy enough to fuse up to iron in the core and explode as a normal iron core-collapse supernova,” said lead author Daichi Hiramatsu, an astronomer at the University of California at Santa Barbara, in an email. “It is just right for the neon and magnesium to capture electrons to convert their protons into neutrons, reducing the core pressure and inducing an electron-capture supernova.”
