Pentadiamond: Scientists Devise a Way to Build a Harder Diamond

Posted by in categories: computing, nanotechnology, particle physics

Scientists at the University of Tsukuba use computer calculations to propose a new way to rearrange the carbon atoms in a diamond to make it even harder, which may be useful in industrial applications that rely on synthetic cutting diamonds.

Researchers at the University of Tsukuba used computer calculations to design a new carbon-based material even harder than diamond. This structure, dubbed “pentadiamond” by its creators, may be useful for replacing current synthetic diamonds in difficult cutting manufacturing tasks.

Diamonds, which are made entirely of carbon atoms arranged in a dense lattice, are famous for their unmatched hardness among known materials. However, carbon can form many other stable configurations, called allotropes. These include the familiar graphite in pencil lead, as well as nanomaterials such as carbon nanotubes. The mechanical properties, including hardness, of an allotrope depend mostly on the way its atoms bond with each other. In conventional diamonds, each carbon atom forms a covalent bond with four neighbors. Chemists call carbon atoms like this as having sp3 hybridization. In nanotubes and some other materials, each carbon forms three bonds, called sp2 hybridization.

Weather looks good for SpaceX’s next Starlink launch from Kennedy Space Center

Posted by in categories: internet, space

The weather forecast looks mostly favorable for the Space Coast’s next launch, a mission slated to see a 230-foot SpaceX Falcon 9 rocket take flight from Kennedy Space Center on Wednesday.

Conditions are shaping up to be 70% “go” for the 11:59 a.m. liftoff from pad 39A, the Space Force said Sunday, thanks to the movement of drier air. Teams will have until 12:05 p.m. to launch.

“On Wednesday, some drier mid-level air will likely move into the area, helping to limit shower and storm coverage compared to earlier in the week,” the 45th Weather Squadron said. “The primary concern for the launch window is the cumulus cloud rule.”

NASA Is Releasing a Fragrance That Smells Like Space

Posted by in categories: chemistry, space

NASA is bringing the smell of space to Earth with a new fragrance called Eau de Space. The fragrance was developed by chemist Steve Pearce, who was contracted by NASA in 2008 to recreate the scent of space.

With his knowledge of flavor and fragrance chemistry, Pearce used astronauts’ descriptions of the smell of space to come up with combinations to match what was described as “ozone, hot metal, and fried steak,” CNN reports.

“It’s a bitter kind of smell in addition to being smoky and burned, kind of like a smell from a gun, right after you fire the shot,” astronaut Peggy Whitson told CNN. Eau de Space product manager, Matt Richmond, said he has struggled to accurately describe the fragrance’s scent, adding that astronauts have also likened the smell to “a mix of gunpowder, seared steak, raspberries, and rum.”

Posthuman Politics and Artificial-Death

Posted by in category: life extension

A better deal than any supernaturalist religion can offer; that seems to me what Julian Huxley intended. Some relief from fear of death. Morality self judged and perhaps situational – but not ethical codes forced on you by an imaginary invisible bullying tyrant(s) or a human calling upon His name…

A lot – possibly most- individuals on trans/ singul/ posthuman lists are drawn to radical futurism for specific reasons of extending life and attaining immortality (continuation of awareness) after physical death by technology. Different groups are working on different projects, but is concentrating on MVT analog circuits with Zenet interface. This is much less ambitious than approaches involving whole brain/ personality/ memory preservation, since there is only need to retain signals relating to game decision making. But who wants to be particularly aware of being dead?

The long countdown to commercial crew’s liftoff

Posted by in category: space travel

Success, the saying goes, has a thousand fathers. Sure enough, when a SpaceX Falcon 9 lifted off May 30, placing a Crew Dragon with two NASA astronauts on board into orbit on the first human orbital spaceflight from U.S. soil in nearly nine years, plenty of prospective parents stepped forward.

President Donald Trump, who attended the launch at the Kennedy Space Center, was quick to take credit for it. “With this launch, the decades of lost years and little action are officially over,” he said in a speech at KSC two hours after liftoff. “Past leaders put the United States at the mercy of foreign nations to send our astronauts into orbit. Not anymore.”

Others cried foul, noting that the commercial crew program started during the Obama administration. In a call with reporters days before the launch, former NASA Administrator Charles Bolden and former Sen. Bill Nelson (D-Fla.) praised work by Joe Biden, Obama’s vice president and the 2020 Democratic nominee for president, to build support for the program in its early years. “He was very much a part of the decision-making that went into this and ultimately brings us to this success,” Nelson said.

New breakthrough in ‘spintronics’ could boost high speed data technology

Posted by in categories: innovation, particle physics

Scientists have made a pivotal breakthrough in the important, emerging field of spintronics—which could lead to a new high speed energy efficient data technology.

An international team of researchers, including the University of Exeter, has made a revolutionary discovery that has the potential to provide high speed, low power-usage for some of the world’s most well-used .

While today’s information technology relies on electronics that consumes a huge amount of energy, the electrons within can also transfer a form of angular momentum called .

Fastest-growing black hole identified

Posted by in category: cosmology

Astronomers report that J2157, discovered in 2018, is now known to have 34 billion solar masses and is consuming the equivalent of nearly 1 solar mass every day, making it the fastest-growing black hole in the Universe.

Physicists Observe Branched Flow of Light

Posted by in categories: entertainment, physics

Physicists from the Technion-Israel Institute of Technology and the University of Central Florida have experimentally observed optical branched flow in liquid soap films.

Instead of producing completely random speckle patterns, the slowly varying disordered potential gives rise to focused filaments that divide to form a pattern resembling the branches of a tree.

Researchers Indicate COVID-19 Mutation Has Made Virus More Contagious

Posted by in categories: biotech/medical, genetics

Researchers from Northwest University’s medical school in Chicago believe a mutation in the coronavirus has made it considerably more contagious.

Infection disease special Egon Ozer of the Feinberg School of Medicine has said that upon examining the genetic structure of coronavirus samples, it was evident there was a change in one of the amino acids that allowed a spike in protein on the surface of the virus.

In layman’s terms, this change has allowed the virus to penetrate nearby cells easier, and as a result the virus can replicate faster and be passed on easier.
