Tech Xplore / Programmable metasurface generates dozens of holograms at once
Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or two-dimensional (2D) images produced by precisely controlling the shape and direction of traveling light ...
Phys.org / Chemists capture structure of the elusive borylnitrene trapped in a crystal using X-ray
Nitrenes are the ghosts of synthetic chemistry, formed in an instant and gone just as quickly, rearranging into something entirely different. These highly reactive intermediates are widely used in synthesis, yet remain notoriously ...
Phys.org / Satellites reveal when toxic algal blooms flare in Blue Mesa Reservoir
The summers of 2021 and 2022 were tough seasons for Colorado's Blue Mesa Reservoir. A severe drought gripped much of the western U.S., prompting emergency water releases that brought the reservoir to its lowest level since ...
Medical Xpress / Researchers discover treatable cause of severe anemia associated with a cancer therapy
Researchers at the Mount Sinai Tisch Cancer Center have identified a previously underrecognized folate deficiency that may cause severe anemia in some patients receiving PARP inhibitors, a widely used class of targeted cancer ...
Science X / Cannibalism could keep people alive—so why did humans reject it almost everywhere?
From ancient graves to stories of survival on the frontier, signs of human flesh-eating turn stomachs, even as they raise questions. Anthropologists have uncovered bones cut up with axes and chops—like a skull from England ...
Medical Xpress / Video games might modestly sharpen your memory and other cognitive skills, review suggests
Because video games are a regular part of many people's everyday lives, researchers have spent a lot of time trying to determine whether they are beneficial or detrimental to brain health. A new study, published in Acta Psychologica, ...
Phys.org / Bioinspired strategy creates complex 3D curved structures via programmed shrinkage
The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces ...
Phys.org / New approach boosts microplastic removal from wastewater
RMIT University researchers have tested a more effective way to capture microplastics from wastewater, using a combination of microbubbles and nanobubbles to achieve removal rates of more than 90%.
Tech Xplore / Why cryogenic sensors may switch to light: New laser moves data fast with less heat
FPAs are image sensors that convert infrared light into electrical signals to produce real-time thermal images and are widely used in applications such as surveillance, astronomy and industrial monitoring. Advances in cryogenic ...
Phys.org / Ancient hobbit-like humans may have survived on meat left behind by Komodo dragons
Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they ...
Phys.org / Universities must rethink how they prepare students for an AI-powered world, study argues
Universities need to rethink how they teach, assess and prepare students for employment as artificial intelligence becomes an increasingly important part of everyday life and work, according to a new study from the University ...
Medical Xpress / Researchers discover molecular 'switch' that simultaneously manages touch and pain
A research team led by Prof. Hyosang Lee of the Department of Brain Sciences at DGIST has identified TWIK-1, a type of potassium channel expressed in the spinal cord and peripheral sensory neurons of the somatosensory system, ...
