‘Scaffolding’ method allows biochemists to see proteins in remarkable detail

UCLA biochemists have achieved a first in biology: viewing at near-atomic detail the smallest protein ever seen by the technique whose development won its...

Warming Greenland ice sheet passes point of no return

Greenland fjord (stock image). Credit: © Di / stock.adobe.com Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue shrinking. The finding, published today, Aug. 13, in the journal Nature Communications Earth and…

Quantum researchers create an error-correcting cat

Schrödinger's cat concept (stock image). Credit: © Katerina Pavlichenko / stock.adobe.com Yale physicists have developed an error-correcting cat -- a new device that combines the Schrödinger's cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a quantum computation. It is…

Inexpensive, accessible device provides visual proof that masks block droplets

Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more…

Researchers use 3D modeling to decode aerial undulation’s role in flying...

Paradise tree snake (stock image). Credit: © Alessandro / stock.adobe.com When the paradise tree snake flies from one tall branch to another, its body ripples with waves like green cursive on a blank pad of blue sky. That movement, aerial undulation, happens in each glide made by members of the Chrysopelea family, the only known…

Teleportation: Important step in improving quantum computing

Quantum computation concept illustration (stock image). Credit: © Maksim Kabakou / stock.adobe.com "Beam me up" is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise. While human teleportation exists only in science fiction,…

Water vapor in the atmosphere may be prime renewable energy source

Credit: © Can Balcioglu / stock.adobe.com The search for renewable energy sources, which include wind, solar, hydroelectric dams, geothermal, and biomass, has preoccupied scientists and policymakers alike, due to their enormous potential in the fight against climate change. A new Tel Aviv University study finds that water vapor in the…

Tiny, magnetically powered neural stimulator

Illustration of neurons (stock image). Credit: © ktsdesign / stock.adobe.com Rice University neuroengineers have created a tiny surgical implant that can electrically stimulate the brain and nervous system without using a battery or wired power supply. The neural stimulator draws its power from magnetic energy and is about the size of a grain of rice.…

Engineers put tens of thousands of artificial brain synapses on a...

Brain on chip abstract concept (stock image). Credit: © Andrey / stock.adobe.com MIT engineers have designed a "brain-on-a-chip," smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors -- silicon-based components that mimic the information-transmitting synapses in the human brain. The researchers borrowed from principles…

Synthetic red blood cells mimic natural ones, and have new abilities

Illustration of red blood cells (stock image). Credit: © phonlamaiphoto / stock.adobe.com Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times. But so far, most artificial red blood cells have had one or a few, but not all,…

Mind-controlled arm prostheses that ‘feel’ are now a part of everyday...

Credit: © TungCheung / Adobe Stock For the first time, people with arm amputations can experience sensations of touch in a mind-controlled arm prosthesis that they use in everyday life. A study in the New England Journal of Medicine reports on three Swedish patients who have lived, for several years, with…

Stabilizing brain-computer interfaces

Brain-computer interface abstract illustration (stock image). Credit: © knssr / Adobe Stock Researchers from Carnegie Mellon University (CMU) and the University of Pittsburgh (Pitt) have published research in Nature Biomedical Engineering that will drastically improve brain-computer interfaces and their ability to remain stabilized during use, greatly reducing or potentially eliminating the need to recalibrate these…

Faster-degrading plastic could promise cleaner seas

Credit: © Richard Carey / Adobe Stock To address plastic pollution plaguing the world's seas and waterways, Cornell University chemists have developed a new polymer that can degrade by ultraviolet radiation, according to research published in the Journal of the American Chemical Society. "We have created a new…

ESO telescope sees star dance around supermassive black hole, proves Einstein...

Black hole concept illustration (stock image). Credit: © vchalup / Adobe Stock Observations made with ESO's Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity. Its orbit is shaped…

Boson particles discovery provides insights for quantum computing

Computing abstract illustration (stock image). Credit: © Siarhei / Adobe Stock Researchers working on a U.S. Army project discovered a key insight for the development of quantum devices and quantum computers. Scientists found that a class of particles known as bosons can behave as an opposite class of particles called fermions, when forced into a…

What do soap bubbles and butterflies have in common?

Common Buckeye Butterfly, Junonia coenia (stock image). Credit: © Tom / Adobe Stock Edith Smith bred a bluer and shinier Common Buckeye at her butterfly farm in Florida, but it took University of California, Berkeley, graduate student Rachel Thayer to explain the physical and genetic changes underlying the butterfly's newly acquired iridescence. In the process,…

University of California, Berkeley, and Lawrence Berkeley National Laboratory (Berkeley Lab) chemists have…

Weighing in on the origin of heavy elements

Periodic table (stock image). Credit: © alexphoto71 / Adobe Stock A long-held mystery in the field of nuclear physics is why the universe is composed of the specific materials we see around us. In other words, why is it made of "this" stuff and not other stuff? Specifically of interest are the physical processes responsible…
