New research shows that clear-air turbulence increased in various regions around the world from 1979 -- 2020.

An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles.

Nutrition is an important part of any top athlete's training program. And now, a new study proposes that supplementing the diet of athletes with colorful fruits and vegetables could improve their visual range. The paper examines how a group of plant compounds that build up in the retina, known as macular pigments, work to improve eye health and functional vision.

Large study in children reveals Selenomonas sputigena as a key partner of Streptococcus in cavity formation.

Octopuses don't thermoregulate, so their powerful brains are exposed to -- and potentially threatened by -- changes in temperature. Researchers report that two-spot octopuses adapt to seasonal temperature shifts by producing different neural proteins under warm versus cool conditions. The octopuses achieve this by editing their RNA, the messenger molecule between DNA and proteins. This rewiring likely protects their brains, and the researchers suspect that this unusual strategy is used widely amongst octopuses and squid.

Stress can override natural satiety cues to drive more food intake and boost cravings for sweets.

Poems, essays and even books -- is there anything the OpenAI platform ChatGPT can't handle? These new AI developments have inspired researchers to dig a little deeper: For instance, can ChatGPT also design a robot? And is this a good thing for the design process, or are there risks?

Researchers have revealed the mechanisms that cause lithium metal solid-state batteries to fail. The new insights could help overcome the technical issues with solid-state batteries, unlocking a game-changing technology for electric vehicles and aviation.

Take a lattice -- a flat section of a grid of uniform cells, like a window screen or a honeycomb -- and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the top grid a twist so that you can see portions of the lower one through it. This new, third pattern is a moiré, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors.

A genomic analysis of ancient human remains from Morocco in northwest Africa revealed that food production was introduced by Neolithic European and Levantine migrants and then adopted by local groups.

A newly discovered plant-eating dinosaur may have been a species' 'last gasp' during a period when Earth's warming climate forced massive changes to global dinosaur populations.

Last year, telescopes around the world registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so dazzling.

A new paper argues that materials like wood, bacteria, and fungi belong to a newly identified class of matter, 'hydration solids.' The new findings emerged from ongoing research into the strange behavior of spores, dormant bacterial cells.

Newly discovered biomarker signatures point to a whole range of previously unknown organisms that dominated complex life on Earth about a billion years ago. They differed from complex eukaryotic life as we know it, such as animals, plants and algae in their cell structure and likely metabolism, which was adapted to a world that had far less oxygen in the atmosphere than today.

Researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the magnetic field near the sun's surface is powerful enough to drive the fast solar wind, which is made up of ionized particles -- called plasma -- that flow outward from the sun.

'Meaning of manual labor' causes consumers to reject autonomous products.

While studying classical novae using the National Radio Astronomy Observatory's Very Long Baseline Array (VLBA), a graduate researcher uncovered evidence the objects may have been erroneously typecast as simple. The new observations detected non-thermal emission from a classical nova with a dwarf companion.

Shallow lakes and ponds emit significant amounts of greenhouse gases into the atmosphere, but emissions from these systems vary considerably and are not well understood.

A simple sponge has improved how robots grasp, scientists have found.

Geochemists report findings from collected and analyzed helium and carbon isotopic data from springs along a nearly 250-mile segment of Alaska's Denali Fault. The fault's mantle fluid flow rates, they report, fall in the range observed for the world's other major and active strike-slip faults that form plate boundaries.
