Brazil's Butantan Institute identified a new mite larvae, Araneothrombium brasiliensis, feeding on a spider in a museum specimen case.

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.

Structural and biochemical studies of influenza virus RNA-dependent RNA polymerase (FluPol) in complex with transcribing host RNA polymerase II reveal the molecular mechanisms of RNA cap snatching by FluPol.

Cryo-electron microscopy and massively parallel assays shed light on the mechanism by which DICER, a key enzyme in the RNase III family, cleaves RNA at precise locations to produce small RNAs.

System can identify genes, regulatory sequences, splice sites, and more.

And it looks like the toxicity can be washed out, meaning it may be possible to cleanse Mars dirt for crop-growing duty.

China is set to perform additional testing of its Mengzhou crew capsule following a successful…

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...

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.

New 3D reconstructions of a key sensory organ in ctenophores reveal an unexpected structural and functional complexity. The findings suggest that an elementary brain may have already appeared in our most ancient relatives, reshaping our understanding of nervo…

The ultraviolet auroras were imaged by NASA's Juno probe on a brief flyby.

Researchers gave chimps crystals. The chimps sorted them from rocks, held them to the light, and refused to return them.

The laws of math, physics, and biology are the only things holding back the King of Monsters.

Astronomers have reported observations of a rare star system consisting of one star orbiting a system of three more tightly bound stars. This quadruple star system is described in a new study, published in Nature Communications, as the most compact quadruple …

NASA has made it official that it does not plan to use the new mobile launcher 2 tower in its revamp of the Artemis program.

We all have a concept of reality. We know what is “fact” and what isn’t. However, the truth of the matter is that the definition of “real” is a mere construct of the brain.

Columnist Natalie Wolchover explores whether applied category theory can be “green” math.

A rare baby dinosaur fossil found in Canada is giving scientists a glimpse into the early life of dome-headed dinosaurs.

The James Webb Space Telescope captured a stunning spiral galaxy 65 million light-years away, revealing glowing dust clouds and stellar nurseries.

Most of the Tampa Bay area had clear skies right before 6 a.m.
