A survey of tropical insect populations and thermal tolerance limits indicates that species from lowland areas have low capacity to survive increased temperatures, and that thermal tolerance is limited by fundamental properties of protein architecture.

PIEZO2 is intrinsically more rigid than PIEZO1, and disparate mechanical stimuli paradoxically evoke opposite conformational and gating responses in each channel.

RNA interference (RNAi) depends on DICER, an essential enzyme that processes RNA precursors into small regulatory RNAs. DICER cleaves RNA precursors according to the 5′-end counting rule, in which RNA length is measured from the 5′-end1–3. Previous work proposed a single 5′-end binding pocket that d

Influenza virus mRNAs are stable and competent for nuclear export and translation because they receive a 5′ cap(1) structure in a process called cap snatching1. During cap snatching, the viral RNA-dependent RNA polymerase (FluPol) binds to host RNA polymerase II (Pol II) and the emerging transcript2

PIEZOs are mechanically gated ion channels that transduce force into electrochemical signals1. PIEZO1 responds to diverse stimuli including membrane stretch2 and shear stress3, whereas PIEZO2 is generally tuned to detect cellular indentation4,5. The functional specialization of PIEZO2 is proposed to

Evo 2 is an artificial intelligence-based biological foundation model trained on 9 trillion DNA base pairs spanning all domains of life that predicts functional properties from genomic sequences and provides a rich generative model for researchers in biology.

A tiny, articulated, near-complete osteichthyan from the early Silurian Chongqing Lagerstätte, represents the oldest osteichthyan occurrence including microfossils, and the earliest articulated remains of any bony fish in the fossil record.

Osteichthyans, comprising sarcopterygians and actinopterygians, dominate modern vertebrate biodiversity1–3, yet their pre-Devonian fossil record remains scarce and fragmentary4,5. The oldest articulated sarcopterygian6 and stem osteichthyan7 date to the late Silurian, whereas undisputed actinopteryg

Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

Human beings have been at the center of ecological change on Earth for thousands of years. But as history shows, no species lasts forever.

VANCOUVER — British Columbians took to social media Tuesday evening to share sightings of a bright fireball in the night sky over Vancouver and a house-rattling sonic boom that an expert says were "un...

Stanford researchers have combined two microscopy techniques to create a one-of-a-kind instrument that can show cell structures interacting in real time at an unprecedented 120-nanometer resolution—the highest achieved without the use of fluorescent labels. T…

The crater left behind from the impact has yet to be found.

A newly documented microscopic animal in Great Salt Lake sediments reveals a hidden layer of life scientists had completely overlooked.

NASA’s Advanced Air Vehicles Program (AAVP) studies, evaluates, and develops technologies and capabilities for new aircraft systems and explores far-future concepts for revolutionary air travel improvements. AAVP develops technologies for all flight regimes from hover to hypersonic to enable safe, n

We're another step closer to finding a real cure for baldness.

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward Earth from 8 billion light-years away and was spotted thanks to a weird space-time trick first predicted by Einstein.

For the first time, a young, Sun-like star has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star in this image released on Feb. 23, 2026. Winds from the star’s sur

Listen to this audio excerpt from Paul Boehm, Orion crew support and thermal systems functional area manager: As the Artemis II astronauts fly around the Moon, they’ll rely on systems inside the Orion spacecraft to live, work, and keep them safe during their mission. At NASA’s Johnson Space Center i

Detached orca fins scored with distinctive tooth marks suggest that killer whale cannibalism is happening — and it might explain some complex orca societies.

The U.S. Office of Personnel Management (OPM) and NASA announced NASA Force on Wednesday, a dedicated talent track within the US Tech Force initiative designed to recruit and deploy the nation’s top engineers and technologists to support America’s space program. NASA Force will identify and place hi

Rivers rise and fall throughout the year, but by how much? Perhaps less than previously thought, according to new data from the SWOT mission. Hidden riverbed contours are also emerging. In a first, a space mission led by NASA and France has tracked Earth’s rivers swelling and shrinking from month to

NASA's Artemis II is on track to shoot for the moon in April after engineers fixed the helium issue that grounded the mission's rocket last month.

This European robot mission could be the key to Mars colonization. Discover how it's exploring the unknown to make it possible.
