A new study uncovers a switchable, atomically-thin metal-organic material that could be used in future low-energy electronic technologies. The study shows that electron interactions in this material create an unusual electrically-insulating phase in which electrons are ‘frozen’. By reducing the population of electrons, the authors are able to unfreeze the remaining electrons, allowing for controlled …
Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida’s Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated …

Hyperspectral imaging (HSI) is a state-of-the-art imaging technique useful for determining the composition of a variety of objects. Specifically, over-thousand-nanometer (OTN) HSI is particularly useful for detecting organic substances and in medical imaging. In a new study, researchers have developed the world’s first rigid endoscope for visible-to-OTN HSI, utilizing supercontinuum lighting and an acoustic-opto tunable …

Scientists have dramatically reduced the time and energy required to chill materials to temperatures near absolute zero. Their prototype refrigerator could prove a boon for the burgeoning quantum industry, which widely uses ultracold materials.

Scientists have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of ‘entropy’ for the phenomenon of quantum entanglement. This finding could help drive a better understanding of quantum entanglement, which is a key resource that underlies much of the power of future quantum computers. Scientists have shown, through probabilistic …

Neuroscientists have artificially increased neuronal activity in part of the brain by briefly shining light on genetically modified neurons. They saw that this manipulation selectively enhanced performance in non-human primates performing a visual attention task, underscoring the crucial role that attention plays in sensory perception. Neuroscientists have artificially increased neuronal activity in part of the …

The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active ‘mainstreaming’ or integration of biodiversity targets into policies and plans across relevant …
Two complementary research articles reveal that central and peripheral circadian clocks coordinate to regulate the daily activity of skin and muscles. The coordination between the two clocks (central and peripheral) guarantees 50% of the circadian functions of tissues, including vital processes such as the cell cycle, DNA repair, mitochondrial activity, and metabolism. Synchronization between the …
Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report.
