I'm sure this will end well. Don't scientists even watch horror movies?In a new study, technology replaces language as a means of communicating by directly linking the activity of human brains. Electrical activity from the brains of a pair of human subjects was transmitted to the brain of a third individual in the form of magnetic signals, which conveyed an instruction to perform a task in a particular manner. This study opens the door to extraordinary new means of human collaboration while, at the same time, blurring fundamental notions about individual identity and autonomy in disconcerting ways.

If networked rat brains are “smarter” than a single animal, imagine the capabilities of a biological supercomputer of networked human brains. Such a network could enable people to work across language barriers. It could provide those whose ability to communicate is impaired with a new means of doing so. Moreover, if the rat study is correct, networking human brains might enhance performance. Could such a network be a faster, more efficient and smarter way of working together?
A flat-Earth conspiracy theorist named Mike Hughes finally lifted off our spherical planet's surface into the skies aboard a self-made, steam-powered rocket Saturday (March 24).
...
In a video by Noize TV (which contains explicit language) yesterday, Hughes is seen stepping into the top cone of the rocket, with his helmet-covered head facing the heavens, the desert mountains in the background. The rocket was nestled into scaffolding attached to Hughes' "Flat Earth" plastered truck.
...
This time, Hughes, a 61-year-old limo driver, crafted a ramp from a mobile home so that he could launch from a vertical angle that would allow him to return to Earth on private land owned by Albert Okura. In Saturday's success, the rocket took off straight into the air, reaching 1,875 feet (572 meters) above the Mojave Desert near Amboy, California, before making a "hard landing which sheared off the nose cone," he posted on his Facebook page.
The cone, with Hughes inside, fell back to Earth attached to a parachute. He was dropping at 350 mph (560 km/h) before pulling his parachute; that wasn't enough to slow him to a reasonable speed, and so Hughes had to pull a second parachute before crashing into the desert, as seen in the Noize TV livestream.
Upon landing, he told the Associated Press that aside from an aching back, he was fine, and "relieved," adding "I'm tired of people saying I chickened out and didn't build a rocket. I'm tired of that stuff. I manned up and did it."
Sometimes, they find both Long’s DNA and his donor’s in the samples, such as when they test swabs from his lip, cheek, and tongue. Samples of his chest and head hair, meanwhile, show only Long’s DNA.
But perhaps most surprisingly, four years after the procedure, samples of Long’s semen show only his donor’s DNA.
“I thought that it was pretty incredible that I can disappear and someone else can appear,” Long told the NYT.
The tail of a feathered dinosaur has been found perfectly preserved in amber from Myanmar.
...
Examination of the specimen suggests the tail was chestnut brown on top and white on its underside.
The tail is described in the journal Current Biology.
...
The study's first author, Lida Xing from the China University of Geosciences in Beijing, discovered the remarkable fossil at an amber market in Myitkina, Myanmar.
The 99-million-year-old amber had already been polished for jewellery and the seller had thought it was plant material. On closer inspection, however, it turned out to be the tail of a feathered dinosaur about the size of a sparrow.
Lida Xing was able to establish where it had come from by tracking down the amber miner who had originally dug out the specimen.
Dr McKellar said examination of the tail's anatomy showed it definitely belonged to a feathered dinosaur and not an ancient bird.

Molecules containing noble gases shouldn’t exist. By definition, these chemical elements — helium, neon, argon, krypton, xenon and radon — are the party poopers of the periodic table, huddling in the rightmost column and refusing to make molecules. Indeed, no one has ever seen any naturally occurring noble gas molecules on Earth. Earlier this decade, though, astronomers accidentally discovered one of these aloof elements in molecules in space.
Then, in 2019, observers reported finding a second kind of noble gas molecule, one they had sought for more than three decades and of a type that was the very first to form after the universe’s birth in the big bang. This newly found molecule lends insight into the chemistry of the early universe, before any stars began to shine or any galaxies had formed. The discovery may even help astronomers understand how the first stars arose.
...
Here on Earth, scientists have been concocting noble gas molecules for nearly a century. In 1925, laboratory scientists were able to force the noble gas helium into a bond with hydrogen to form helium hydride, or HeH+ — termed a molecule by astronomers but, because it’s electrically charged, a molecular ion by chemists.
...
University College London astrophysicist Mike Barlow ... led the team that accidentally found ArH+: argonium, which consists of argon and hydrogen.
...
To this day no one has ever detected any helium hydride in the early universe; that would require the unprecedented feat of looking across more than 13 billion light-years of space to the dawn of time and discerning the faint spectral line that the molecule produces. In April 2019, however, astronomers led by Rolf Güsten of the Max Planck Institute for Radio Astronomy in Germany reported finding the long-sought molecule right here in the Milky Way.
Güsten’s team made the discovery not with a spacecraft but with a specialized airplane that flies above nearly all of the atmosphere’s water vapor, which blocks infrared radiation. The Stratospheric Observatory for Infrared Astronomy hunted for the coveted molecule using a telescope with a sensitive new high-resolution spectrometer. This instrument successfully detected the far-infrared signature of HeH+ at a wavelength of 149 micrometers.
Güsten and his colleagues succeeded by searching the same nebula where their predecessors had failed: NGC 7027 in the constellation Cygnus. Here, about 600 years ago, an aging star known as a red giant shed its atmosphere — something our own sun will do in about 7.8 billion years. This exposed the dying star’s hot core, which shines at a blistering 190,000 kelvins (340,000 degrees Fahrenheit) and emits extreme ultraviolet light that tears electrons from helium atoms, creating He+. Combine that with neutral hydrogen atoms from other parts of the nebula and you have HeH+. In the early universe it was the other way around — charged hydrogen and neutral helium — but the end result was the same: HeH+, the first molecule to form after the big bang.

Micro-angelo? This 3D-printed ‘David’ is just one millimeter tall.
It was created using Exaddon’s “CERES” 3D printer, which lays down a stream of ionized liquid copper at a rate of as little as femtoliters per second, forming a rigid structure with features as small as a micrometer across. The Tiny David took about 12 hours to print, though something a little simpler in structure could probably be done much quicker.
The use of sulfur cathodes in lithium-sulfur (Li-S) batteries and silicon anodes in lithium-ion batteries (LIBs) is the most attractive example of inexpensive electrodes with excellent ability to store lithium, hence the potential for outperforming today’s LIBs. An inherent problem of these electrodes, regardless of the battery chemistry, is the structural fragmentation associated with the inevitable volume change during the absorption and release of large quantities of lithium.
...
In addition to improving the performance of sulfur cathodes, a shift from networking mechanism to bridging mechanism may provide advantages to other high-capacity electrode materials such as the highly investigated Si anode in Li-ion battery. All these attractive performance features, along with low cost, environmental friendliness, abundance of materials available, and ease of processing, make this new design of electrodes promising for large-scale real-world applications as demonstrated with our Li-S pouch cells.
And not just the kind linked to a single type of cancer, either. When the Cardiff researchers equipped T-cells in lab tests with this new TCR, the cells killed lung, skin, blood, colon, breast, bone, prostate, ovarian, kidney and cervical cancer cells — all while ignoring healthy cells.

I can't think of many things more irresponsible than funding programming on and encouragement of "Homemade Astronauts." Shame on the so-called Science Channel.The stunt was apparently part of a forthcoming television show, "Homemade Astronauts," that was scheduled to debut later this year on Discovery Inc.'s Science Channel.
Discovery confirmed the 64-year-old's death in a statement.
"It was always his dream to do this launch, and Science Channel was there to chronicle his journey," the company said.
