Visual short-term memory is more complex than previously assumed
Contrary to previous assumptions, visual short-term memory is not merely based on one kind of information about an object, such as only its colour or only its name. Rather, several types of information can be retained simultaneously in short-term memory. Using complex EEG analyses and deep neural networks, researchers at Beijing Normal University and Ruhr-Universität Bochum have discovered that short-term memory is more complex than previously assumed.

Tension between awareness and fatigue shapes Covid-19 spread
In the midst of the coronavirus pandemic, two human factors are battling it out: awareness of the virus's severe consequences and fatigue from nine months of pandemic precautions. The results of that battle can be seen in the oddly shaped case, hospitalization, and fatality-count graphs, a new study suggests.

NSF-funded deep ice core to be drilled at Hercules Dome, Antarctica
Antarctica's next deep ice core, drilling down to ice from 130,000 years ago, will be carried out by a multi-institutional U.S. team at Hercules Dome, a location hundreds of miles from today's coastline and a promising site to provide key evidence about the possible last collapse of the West Antarctic Ice Sheet.

Quick and sensitive identification of multidrug-resistant germs
Researchers from the University of Basel have developed a sensitive testing system that allows the rapid and reliable detection of resistance in bacteria. The system is based on tiny, functionalized cantilevers that bend due to binding of sample material. In the analyses, the system was able to detect resistance in a sample quantity equivalent to 1-10 bacteria.

Rise of the underdog: a neglected mechanism in antiferromagnets may be key to spintronics
Scientists at Tokyo Institute of Technology (Tokyo Tech) discover a mechanism in antiferromagnets that could be useful for spintronic devices. They theoretically and experimentally demonstrate that one of the magnetization torques arising from optically driven excitations has a much stronger influence on spin orientation than previously given credit for. These findings could provide a new and highly efficient mechanism for manipulating spin.

Harnessing quantum properties to create single-molecule devices
Researchers, led by Columbia Engineering Prof Latha Venkataraman, report today that they have discovered a new chemical design principle for exploiting destructive quantum interference. They used their approach to create a six-nanometer single-molecule switch where the on-state current is more than 10,000 times greater than the off-state current--the largest change in current achieved for a single-molecule circuit to date.
