“The surprising thing we found is that in a particular kind of crystal lattice, where electrons become stuck, the strongly coupled behavior of electrons in d atomic orbitals actually act like the f orbital systems of some heavy fermions,” said Qimiao Si, co-author of a study about the research in Science Advances

<em> Science Advances </em> is a peer-reviewed, open-access scientific journal that is published by the American Association for the Advancement of Science (AAAS). It was launched in 2015 and covers a wide range of topics in the natural sciences, including biology, chemistry, earth and environmental sciences, materials science, and physics.

Oh boy. What could go wrong?

Scientists trying to take advantage of the unusual properties of the quantum realm say they have successfully simulated a method of backward time travel that allowed them to change an event after the fact one out of four times. The Cambridge University team is quick to caution that they have built a time machine, per se, but also note how their process doesn’t violate physics while changing past events after they have happened.

“Imagine that you want to send a gift to someone: you need to send it on day one to make sure it arrives on day three,” explained lead author David Arvidsson-Shukur from the Cambridge Hitachi Laboratory. “However, you only receive that person’s wish list on day two.”

While it is well known that certain brain regions play a crucial role in memory processes, so far it has not been clear whether these regions exhibit different activities when it comes to storing information in people with better or worse memory performance.

Having investigated this matter, a research team led by Professor Dominique de Quervain and Professor Andreas Papassotiropoulos has now published its results in the journal Nature Communications.

In the world’s largest functional imaging study on memory, they asked nearly 1,500 participants between the ages of 18 and 35 to look at and memorize a total of 72 images. During this process, the researchers recorded the subjects’ brain activity using MRI. The participants were then asked to recall as many of the images as possible – and as in the general population, there were considerable differences in memory performance among them.

Patch now if you haven’t already: Adobe Acrobat Reader exploits are in the wild. #Adobe

The Cybersecurity Infrastructure & Security Agency (CISA) this week added to its catalog of known exploited vulnerabilities an Adobe Acrobat Reader use-after-free bug.

Adobe Acrobat and Reader Document Cloud Versions 22.003.20282 and 22.003.20281 and earlier contain the flaw (CVE-2023–21608), as do Adobe Acrobat and Reader 20.005.30418 and earlier. The use-after-free vuln allows an attacker to remotely execute malicious code on a compromised account, and execute the exploit when a victim opens the rigged PDF file.

Relief could be on the way for people with painful hand osteoarthritis after a Monash University and Alfred Health-led study found an affordable existing drug can help. Until now there has been no effective treatment.

Published in The Lancet, the paper investigated methotrexate, a low-cost, effective treatment for inflammatory joint conditions such as rheumatoid arthritis and psoriatic arthritis. It has been widely used in Australia and globally since the early 1980s.

Researchers found that methotrexate reduced symptoms in those with hand osteoarthritis (OA). A 20mg weekly oral dose over six months had a moderate effect in reducing pain and stiffness in patients with symptomatic hand OA.
