Time To Rethink Theories: Physicists Predict Neutron Stars May Be Bigger Than Previously Imagined

Posted by in categories: cosmology, physics

When a massive star dies, first there is a supernova explosion. Then, what’s left over becomes either a black hole or a neutron star.

That neutron star is the densest celestial body that astronomers can observe, with a mass about 1.4 times the size of the sun. However, there is still little known about these impressive objects. Now, a Florida State University researcher has published a piece[1] in Physical Review Letters arguing that new measurements related to the neutron skin of a lead nucleus may require scientists to rethink theories regarding the overall size of neutron stars.

Amazon Founder Jeff Bezos to Be on Blue Origin’s First Human Space Flight

Posted by in category: space travel

Jeff Bezos plans to travel to space next month as one of the first passengers carried by Blue Origin, the Amazon.com Inc. founder’s space company.

Mr. Bezos said in an Instagram post Monday that he will be one of the inaugural passengers on Blue Origin’s New Shepard spacecraft, during its first crewed flight scheduled for launch from West Texas on July 20. Mr. Bezos said that his brother, Mark Bezos, will also be on board.

“I want to go on this flight because it’s a thing I’ve wanted to do all my life,” Mr. Bezos said in a video posted to Instagram. “It’s an adventure. It’s a big deal for me.”

New tech cheaply produces lithium and H2, while desalinating seawater

Posted by in categories: chemistry, security, sustainability

With the rise of the lithium-based battery, demand for this soft, silvery-white metal – the lightest solid element in the periodic table – has exploded. With the race to zero carbon by 2050 gathering steam, forcing the electrification of transport, lithium will be an even more valuable asset in the next 30 years.

The supply of raw materials for batteries could even end up being a national security issue, too; China’s global leadership on high-volume EV production has put it ahead of the game, and while the majority of ground-based lithium reserves are in the “lithium triangle” of Chile, Bolivia and Argentina, China controls more than half’s the world’s supply simply through investments and ownership. It has shown in the past that it’s not afraid to wield commodity supplies as a weapon.

But as with other metals like uranium, land-based lithium reserves pale in comparison to what’s out there in the sea. According to researchers at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), there’s about 5000 times as much lithium in the oceans as there is in land deposits, and a newly developed technology could start extracting it cheaply enough to make the big time – while producing hydrogen gas, chorine gas and desalinated water as a bonus.

The U.S. South may see a Covid surge this summer as vaccination rates lag

Posted by in categories: biotech/medical, health

A dozen states — many of them in the Northeast, including Maine, Massachusetts and Connecticut — have already reached a benchmark of at least 70 percent of adults with at least one vaccine dose, a goal President Biden has set for the nation to make by July 4. But in the South, that marker is nowhere in sight for several states.

In 15 states — including Arkansas, the Carolinas, Georgia and Louisiana — about half of adults or fewer have received a dose, according to a New York Times analysis. In two states, Alabama and Mississippi, it would take about a year to get one dose to 70 percent of the population at the current pace of distribution.

Public-health experts and officials in states with lower vaccination rates say the president’s benchmark will help reduce cases and deaths but is somewhat arbitrary — even if 70 percent of adults are vaccinated, the virus and its more contagious variants can spread among those who are not.

Gene Changes Linked to Severe Repetitive Behaviors

Posted by in categories: biotech/medical, neuroscience

Summary: Study identifies genes that become activated in the brain prior to the initiation of severe repetitive behaviors associated with addiction, ASD, and schizophrenia.

Source: MIT

Extreme repetitive behaviors such as hand-flapping, body-rocking, skin-picking, and sniffing are common to a number of brain disorders including autism, schizophrenia, Huntington’s disease, and drug addiction. These behaviors, termed stereotypies, are also apparent in animal models of drug addiction and autism.

Smashing gold with finesse: Shockless compression experiments establish new pressure scales

Posted by in categories: chemistry, computing, particle physics, quantum physics

To test the Standard Model of particle physics, scientists often collide particles using gigantic underground rings. In a similar fashion, high-pressure physicists compress materials to ever greater pressures to further test the quantum theory of condensed matter and challenge predictions made using the most powerful computers.

Pressures exceeding 1 million atmospheres are capable of dramatically deforming atomic electronic clouds and alter how atoms are packed together. This leads to new chemical bonding and has revealed extraordinary behaviors such as helium rain, the transformation of sodium into a transparent metal, the emergence of superionic water ice and the transformation of hydrogen into a metallic fluid.

With new techniques constantly advancing the frontier of high– physics, terapascal (TPa) pressures that were once inaccessible can now be achieved in the laboratory using static or dynamic compression (1 TPa is equivalent to approximately 10 million atmospheres).

New study finds most adults would not take a life extension pill, even if it existed

Posted by in categories: biotech/medical, life extension

Mark my words. When the first real treatment happens people will change their tune. They need to see it work and see that it’s safe.


A new study of about 900 U.S. adults has found that only 33% would use a hypothetical life extension treatment that would allow them “to live forever,” even if it were available today. About 42% said they would not use it, and 25% said they were unsure.

The study, published by University of Texas researchers Michael Barnett and Jessica Helphrey, appeared in the Journal of Aging Studies on April 21.

How China is using automation to reshape its economy | CNBC Reports

Posted by in categories: economics, robotics/AI

China’s economy is facing several risks: an aging population, less working-age people, and rising wages. So how is the country responding to these threats? A big part of the answer is automation. From factories to warehouses, several industries are pushing to automate more of their workforce. CNBC’s Arjun Kharpal spoke to China’s largest retailer, JD.com about its new smart logistics center, and examined what comes next for the world’s second largest economy.
