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.

Age-related heart disease linked to gut bacteria metabolite

Posted by in categories: biotech/medical, chemistry, food, life extension

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

High blood levels of trimethylamine-N-Oxide (TMAO), a metabolic byproduct of digestion, have been strongly linked to negative cardiovascular health. When one eats red meat, eggs or other animal proteins, certain types of gut bacteria feed on chemicals in those foods and produce TMA, or trimethylamine, which is then turned into TMAO in the liver.

A number of studies have linked TMAO to heart disease, however, until now it hasn’t been clear exactly how this metabolite causes cardiovascular damage. A robust new study, published in the journal Hypertension, is offering one of the first thorough mechanistic investigations illustrating how TMAO damages the cardiovascular system.
