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...

Touch definition (stock image). 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

"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?

Credit: © oraziopuccio / Adobe Stock If humans ever hope to colonize Mars, the settlers will need to manufacture on-planet a huge range of organic compounds, from fuels to drugs, that are too expensive to ship from Earth. 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…

Device brings silicon computing power to brain research and prosthetics

Abstract illustration of neuron and binary code (stock image). Credit: © robsonphoto / Adobe Stock Researchers at Stanford University have developed a new device for connecting the brain directly to silicon-based technologies. While brain-machine interface devices already exist -- and are used for prosthetics, disease treatment and brain research -- this latest device can record…

The right dose of geoengineering could reduce climate change risks

View of Earth from space (stock image). Credit: © studio023 / Adobe Stock Stratospheric aerosol geoengineering is the idea that adding a layer of aerosol particles to the upper atmosphere can reduce climate changes caused by greenhouse gases such as carbon dioxide. Previous research shows that solar geoengineering could be achieved using commercially available aircraft…

Pollution: A possible end to ‘forever’ chemicals

Filling a glass with tap water (stock image). Credit: © Dmitry Naumov / Adobe Stock Synthetic chemicals known as per- and polyfluoroalkyl substances (PFASs) contain bonds between carbon and fluorine atoms considered the strongest in organic chemistry. Unfortunately, the widespread use of these nonbiodegradable products since the 1940s has contaminated many water supplies across America.…

Water splitting advance holds promise for affordable renewable energy

Model water molecules illustration (stock image). Credit: © fotomek / Adobe Stock A breakthrough into splitting water into its parts could help make renewable energy pay off, even when the sun isn't shining and the wind isn't blowing. Using solar and wind power when it is available for water splitting, a process that uses electricity…

Design of inorganic materials for brain-like computing

Brain-like computing abstract illustration (stock image). Credit: © Sergey Tarasov / Adobe Stock Ever wish your computer could think like you do or perhaps even understand you? That future may not be now, but it's one step closer, thanks to a Texas A&M University-led team of scientists and engineers and their recent discovery of a…
