Graphene has already proven itself to be a weird and wonderful material in many different ways, but its properties get even more unusual and exotic when it’s twisted – and two new studies have given scientists a much closer look at this intriguing phenomenon.

When two sheets of graphene are put together at slightly different angles, the resulting material becomes either very effective at conducting electricity, or very effective at blocking it. It’s known as ‘magic-angle’ twisted graphene, and knowing more about how and why this happens could lead to advances in high-temperature superconductors and quantum computing.

Now for the first time, scientists have mapped out a twisted graphene structure in its entirety, and at a very high resolution. They’ve also been able to get ‘graphene twistronics’ working with four layers of graphene as well as just two.

Even as dramatic social change has been imposed by COVID-19, the kinds of fraud attacks companies experience and the biometric authentication technologies they use to prevent them have remained basically the same. What has changed is that online volumes of traffic, transactions and authentications have reached levels they were expected to years in the future, BehavioSec VP of Products Jordan Blake told Biometric Update in an interview.

As a result, he says, “timelines are getting advanced.”

Demand is coming from new verticals, according to Blake, as numerous people begin using the online channel to interact with many organizations they never have dealt with that way before.

These past two months have been among the most extraordinary times any of us can remember. The COVID-19 (CV-19) impact is all around us, indiscriminately impacting all of our lives, our work, the economy and for sure we are on the onset of a new normal that we are learning how to deal with daily.

There are always two stages of dealing with a change of this magnitude. First, we react immediately, thinking about what we must do differently now. Soon, we will begin to think in the longer term, reacting to and planning for permanent changes that result from the CV-19 pandemic.

With the biggest launch in nearly a decade two weeks away, it’s been a two-horse race in the new “space race”.

UCSC researchers developed a deep-learning framework called Morpheus to perform pixel-level morphological classifications of objects in astronomical images.

Researchers at UC Santa Cruz have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to identify and classify all of the galaxies and stars in large data sets from astronomy surveys.

Morpheus is a deep-learning framework that incorporates a variety of artificial intelligence technologies developed for applications such as image and speech recognition. Brant Robertson, a professor of astronomy and astrophysics who leads the Computational Astrophysics Research Group at UC Santa Cruz, said the rapidly increasing size of astronomy data sets has made it essential to automate some of the tasks traditionally done by astronomers.

In the near future, we will have manned drones going at blistering speeds and doing crazy aerobatic stunts.

Researchers use energy from a next-generation particle accelerator to probe microfossils inside ancient Earth rocks.

“We’ve wondered if it might be possible to simply rewind the aging clock without inducing pluripotency,” said Vittorio Sebastiano, assistant professor at Stanford University and senior author of the Nature Communications article. “Now we’ve found that tightly controlling the exposure to these proteins can promote rejuvenation in multiple human cell types, including stem cells. This has profound implications for regeneration and restoration of cell functionality of aged tissues.”

MOUNTAIN VIEW, Calif., March 25, 2020 /PRNewswire/ — A study published in the respected Nature Communications journal highlights the promise of technology being developed by Turn Biotechnologies to treat age-related health conditions.

The study by researchers at the Stanford University School of Medicine found that old human cells can be induced into a more youthful and vigorous state when they are exposed to a rejuvenating treatment that triggers the limited expression of a group of proteins known as Yamanaka factors, which are important to embryonic development.

The most comprehensive national study to date has found that convalescent plasma appears to be safe to use on COVID-19 patients, a promising development in the race to find a treatment for the deadly virus. But the study didn’t determine whether the treatment works.

A team of more than 5,000 doctors from over 2,000 hospitals and laboratories have been testing the experimental therapy, which involves transfusing the antibody-rich blood serum of recovered COVID-19 patients into people who are battling the illness.
