A new artificial material mimics quantum-entangled rare earth compounds

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

Physicists have created a new ultra-thin, two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality.

The researchers showed that by starting from seemingly common materials, a radically new quantum state of matter can appear. The discovery emerged from their efforts to create a quantum spin liquid which they could use to investigate emergent quantum phenomena such as gauge theory. This involves fabricating a single layer of atomically thin tantalum disulphide, but the process also creates islands that consist of two layers.

It’s a Bus. It’s a Train. It’s Both!

Posted by in categories: economics, energy, transportation

Circa 2008


What do you get when you cross a bus with a train? A dual-mode vehicle that has the versatility of a bus, the speed of light rail and fuel economy vastly better than either. Toyota and its truck-making subsidiary Hino Motors have signed on with Japan Rail Hokkaido to develop the vehicles, which carry 25 […].

SpaceX Falcon 9 rocket aces first interplanetary launch

Posted by in categories: drones, space travel

SpaceX has aced its first operational interplanetary launch, sending NASA’s Double Asteroid Redirection Test (DART) spacecraft on its way out of the Earth-Moon system as part of the world’s first planetary defense mission.

Right on time, SpaceX’s flight-proven Falcon 9 booster lifted off at 10:21 pm PST with an expendable upper stage, new fairing, and the ~630 kg (~1400 lb) DART spacecraft in tow, reaching a nominal low Earth parking orbit about eight minutes later. A few seconds after the second stage’s first engine cutoff (SECO-1), booster B1063 safely landed on drone ship Of Course I Still Love You (OCISLY), wrapping up its third orbital-class launch and spaceflight in twelve months.

Around 28 minutes after liftoff, Falcon 9’s orbital second stage fired up for the second and final time. In just 53 seconds, Falcon 9’s upper stage accelerated from a stable velocity (relative to Earth’s surface) of 7.5 kilometers per second (4.7 mi/s) to almost 11.1 km/s (6.9 mi/s), sending DART (and itself) from low Earth orbit (LEO) to an Earth escape trajectory that will ultimately leave them in orbit around the sun.

Elon Musk Explains On Twitter Why The Cybertruck Has Been Delayed So Much

Posted by in categories: Elon Musk, sustainability, transportation

Tesla CEO Elon Musk came out some days ago to try to make a few things clear. He gave an explanation to why the Cybertruck has been postponed so many times, especially why it’s so difficult to produce new cars. In the list of Teslas postponed new vehicles is the Cybertruck, and Tesla s, and we could also include the tesla roadster which has also been postponed so many times seeing as it’s going to be coming with a completely new design from its predecessor. Let’s get into More detail on Elons reason for postponing the launch of these vehicles so much.

Refinery that supplies most gas used in B.C.‘s Lower Mainland halting work

Posted by in category: futurism

Parkland Corp. is moving to pause its refinery processing operations in Burnaby, B.C., due to a lack of crude oil supply from the Trans Mountain pipeline, which has been shut down as a precaution due to the flooding in B.C.

The company says it plans to maintain the refinery, which is a key source of gasoline for the Vancouver area, on standby mode so that it can resume processing quickly.

“We are maintaining the refinery in ready-mode…which positions us to recommence processing once sufficient crude oil feedstocks become available”, Ryan Krogmeier, Parkland’s senior vice-president of refining, said in a statement.

How AI Is Deepening Our Understanding of the Brain

Posted by in categories: biological, information science, robotics/AI

Artificial neural networks are famously inspired by their biological counterparts. Yet compared to human brains, these algorithms are highly simplified, even “cartoonish.”

Can they teach us anything about how the brain works?

For a panel at the Society for Neuroscience annual meeting this month, the answer is yes. Deep learning wasn’t meant to model the brain. In fact, it contains elements that are biologically improbable, if not utterly impossible. But that’s not the point, argues the panel. By studying how deep learning algorithms perform, we can distill high-level theories for the brain’s processes—inspirations to be further tested in the lab.

Can a Machine Learn Morality?

Researchers at a Seattle A.I. lab say they have built a system that makes ethical judgments. But its judgments can be as confusing as those of humans.

We might not know half of what’s in our cells, new AI technique reveals

Posted by in categories: biotech/medical, chemistry, media & arts, robotics/AI

Most human diseases can be traced to malfunctioning parts of a cell—a tumor is able to grow because a gene wasn’t accurately translated into a particular protein or a metabolic disease arises because mitochondria aren’t firing properly, for example. But to understand what parts of a cell can go wrong in a disease, scientists first need to have a complete list of parts.

By combining microscopy, biochemistry techniques and , researchers at University of California San Diego School of Medicine and collaborators have taken what they think may turn out to be a significant leap forward in the understanding of human cells.

The technique, known as Multi-Scale Integrated Cell (MuSIC), is described November 24, 2021 in Nature.

Electrons set the stage for neutrino experiments

Posted by in category: particle physics

Neutrinos may be the key to finally solving a mystery of the origins of our matter-dominated universe, and preparations for two major, billion-dollar experiments are underway to reveal the particles’ secrets. Now, a team of nuclear physicists have turned to the humble electron to provide insight for how these experiments can better prepare to capture critical information. Their research, which was carried out at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility and recently published in Nature, reveals that major updates to neutrino models are needed for the experiments to achieve high-precision results.

Neutrinos are ubiquitous, generated in copious numbers by stars throughout our universe. Though prevalent, these shy particles rarely interact with matter, making them very difficult to study.

“There is this phenomenon of neutrinos changing from one type to another, and this phenomenon is called . It’s interesting to study this phenomenon, because it is not well understood,” said Mariana Khachatryan, a co-lead author on the study who was a graduate student at Old Dominion University in Professor and Eminent Scholar Larry Weinstein’s research group when she contributed to the research. She is now a postdoctoral research associate at Florida International University.

NASA And SpaceX Launch Experimental Spacecraft That Will Collide With An Asteroid —But It’s Not ‘Armageddon’

Posted by in categories: asteroid/comet impacts, existential risks, satellites

NASA on Tuesday night successfully launched its experimental asteroid deflecting spacecraft which is set to smash into an asteroid at 15,000 miles per hour and serve as a test run for countering any future doomsday scenario where a large space rock could end up on a collision course with the Earth.

KEY FACTS The Double Asteroid Redirection Test (DART), developed by NASA and the European Space Agency (ESA) launched from California’s Vandenberg Space Force Base at around 10.20 a.m. local time Tuesday, aboard SpaceX’s reusable Falcon 9 rocket.

Sometime in 2022, the DART spacecraft is expected to smash into the asteroid Dimorphos which orbits a larger satellite called Didymos—neither of which pose a threat to Earth at the moment—with the hope of deflecting its course.
