Robust superconductivity in magic-angle multilayer graphene family

Posted by in category: materials

😗Year 2022

Superconductivity is reported in magic-angle twisted four-layer and five-layer graphene systems. While they find that all magic-angle graphene systems fit into a unified hierarchy of systems that share a set of flat bands in their electronic band structures, they also report that there is a key distinction between magic-angle twisted bilayer graphene and the other family members, related to the difference in the way the electrons move between the layers in a magnetic field.

SpaceX Starship’s next launch ‘probably 3 to 5 weeks’ away, Elon Musk says

Posted by in categories: Elon Musk, space travel

We’re likely still a month or so away from the next launch of SpaceX’s Starship megarocket.

That was the timeline Elon Musk offered in a post on X over the weekend, saying Starship’s next test flight is “probably 3 to 5 weeks” away. “Objective is for the ship to get past max heating, or at least further than last time,” the billionaire entrepreneur added.

Hackers are now targeting the children of corporate executives in elaborate ransomware attacks

Posted by in category: cybercrime/malcode

In February, ransomware attackers targeted Chain Healthcare, the payment management arm of healthcare giant UnitedHealth Group, causing backlogs in prescription insurance claims.

Ransomware can be introduced to a company’s databases through even the smallest slip by an employee, like clicking a link in a phishing email. But as companies have gotten better at keeping criminals out, the crooks have gotten more creative, Mandiant CTO Charles Carmakal says.

Scientists find sleep may not clear brain toxins

Posted by in category: neuroscience

The brain’s ability to rid itself of toxins may actually be reduced during sleep, contrary to the leading scientific theory.

Over the past decade, the leading explanation for why we sleep has been that it provides the brain with an opportunity to flush out toxins.

However, a new study led by scientists at the UK Dementia Research Institute (UK DRI) at Imperial College London indicates that this may not be true.

Opinion: America Needs Apollo Program for AI Race

Posted by in categories: government, robotics/AI

(TNS) — The global race for computational power is well underway, fueled by a worldwide boom in artificial intelligence. OpenAI’s Sam Altman is seeking to raise as much as $7 trillion for a chipmaking venture. Tech giants like Microsoft and Amazon are building AI chips of their own. The need for more computing horsepower to train and use AI models—fueling a quest for everything from cutting-edge chips to giant data sets—isn’t just a current source of geopolitical leverage (as with US curbs on chip exports to China). It is also shaping the way nations will grow and compete in the future, with governments from India to the UK developing national strategies and stockpiling Nvidia graphics processing units.

I believe it’s high time for America to have its own national compute strategy: an Apollo program for the age of AI.

In January, under President Biden’s executive order on AI, the National Science Foundation launched a pilot program for the National AI Research Resource (NAIRR), envisioned as a “shared research infrastructure” to provide AI computing power, access to open government and nongovernment data sets, and training resources to students and AI researchers.

Enhancing Boiling Processes for Lunar and Martian Exploration

Posted by in categories: futurism, space

How will liquids boil under reduced gravity, specifically on the Moon and Mars? This is what a recent project hopes to address as a team of researchers led by the Southwest Research Institute (SwRI) and working with Texas A&M University investigated the behavior of boiling liquids under reduced gravity using parabolic flights that are designed to simulate reduced gravity conditions. This project holds the potential to help researchers and future astronauts better understand how to manage boiling liquids during long-term space missions to the Moon and Mars where the gravity is one-sixth and one-third of the Earth’s, respectively.

“We have so little data about how boiling works in reduced gravity,” said Kevin Supak, who is a program manager at SwRI and the project lead. “Our experiment studies boiling in conditions that simulate lunar and Martian gravity levels using four different surfaces to examine how bubbles initiate and detach.”
