The humpback chub, a rare fish found only in the Colorado River basin, has been brought back from the brink of extinction after decades of protection, though work must continue to ensure its survival, federal authorities said Monday in reclassifying the species from endangered to threatened status.

Researchers from Cornell University are blending food science expertise and computer programming savvy to help the food industry stop Listeria outbreaks.

Understanding how proteins bend, twist, and shape-shift as they go about their work in cells is enormously important for understanding normal biology and diseases. But a deep understanding of protein dynamics has generally been elusive due to the lack of good imaging methods of proteins at work. Now, for the first time, scientists at the UNC School of Medicine have invented a method that could...

If you're like most cellphone users, at one point you have experienced a cracked screen.

Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can. While a fundamental solvability problem known as "barren plateaus" has limited the application of these neural networks for large data sets, new research overcomes that Achilles heel with a rigorous proof that guarantees...

Thanks to two microphones aboard NASA's Perseverance rover, the mission has recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel, and motors whirring as the spacecraft moves its arm. These sounds allow scientists and engineers to experience the Red Planet in new ways—and everyone is invited to listen in.

Americans may respect and admire how individual billionaires—think Oprah Winfrey or Bill Gates—made their billions, even as they rage against the "top 1%" as a group, new research finds.

A veteran gorilla descended from a celebrated forebear immortalised on a banknote has been found dead near a national park in the Demoratic Republic of Congo, the protected reserve announced on Monday.

Nearly half of our DNA has been written off as junk, the discards of evolution: Sidelined or broken genes, viruses that got stuck in our genome and were dismembered or silenced, none of it relevant to the human organism or human evolution.

Animals that migrate north to breed are being put at risk by ongoing climate change and increasing human pressure, losing earlier advantages for migration, declining in numbers and faring much worse than their resident counterparts, according to scientists writing in Trends in Ecology & Evolution.

The Biden administration is launching a broad strategy to regulate toxic industrial compounds associated with serious health conditions that are used in products ranging from cookware to carpets and firefighting foams.

With future space exploration in mind, a Cornell-led team of astronomers has published the final maps of Titan's liquid methane rivers and tributaries—as seen by NASA's late Cassini mission—so that may help provide context for Dragonfly's upcoming 2030s expedition.

Peatlands are valuable ecosystems that store water and large quantities of carbon and that support high biodiversity. However, 20 percent of the European raised bog habitat is currently under threat from climate change and dewatering.

Life depends on death—living things die, decompose and eventually become nutrients for other life.

Nestled deep in the middle of the vertebrate brain is a multi-sensory integration and movement control center called the superior colliculus. In rodents, this brain region integrates multi-sensory inputs—visual cues, sounds, touch information, and smells—and delivers output signals to a variety of motor control centers in the brain, coordinating the animal's movements in response to its...

Magic-angle twisted bilayer graphene is a material made of two sheets of graphene placed on top of each other, with one sheet twisted at precisely 1.05 degrees with respect to the other. This material has been found to be a very promising platform for studying different phases of matter, as it combines metallic, superconducting, magnetic and insulating phases in a single crystal.

A newly developed catalyst with unique, atomic-sized "rafts" does a better job than current technology for cleaning up emissions from natural gas engines. 

Baker's yeast, Saccharomyces cerevisiae, is used industrially to produce a great variety of biochemicals. These biochemicals can be produced from waste material from the agricultural or forest industry (second-generation biomass). During the mechanical and enzymatic degradation of biomass acetic acid is released. Acetic acid inhibits the growth and the biochemical production rate of yeast. Now,...

Fruits can be dichotomously classified as fleshy or dry. Although many factors have been proposed to explain the pattern that the fleshy-fruited species occur with deceasing latitude and altitude, the relative importance of these factors has not yet been resolved. 

Viruses influence the sex life of the roundworm C. elegans. Male roundworms of this non-parasitic nematode species are less sexually attracted to females infected with the Orsay virus. The virus also eventually leads to more male offspring and therefore an increase in mating behavior. This has been shown in doctoral research by microbiologist Lisa van Sluijs, lecturer at the Laboratory of...

A better knowledge of the causes of disease, birth defects and genetic syndromes could come from new insights gleaned by RIKEN biologists into how mice embryos develop asymmetry between their left and right sides.

The LHC experiments are nearing the completion of maintenance and upgrade works carried out in the framework of the second long shutdown of CERN's accelerator complex. Of all the experiments, LHCb is undergoing the most significant metamorphosis during these two years, namely the installation of a faster Vertex Locator (VELO), a new scintillating-fiber particle-tracking detector (SciFi), and...

Different from the narrow band emission based on free excitons in lead-perovskite nanocrystals (NCs), the low electronic dimensionality in lead-free double perovskite NCs can lead to self-trapped excitons (STEs), generating a broadband emission.

Researchers at the Paul Scherrer Institute PSI have identified a chemical compound that may be suitable as an active agent against several different unicellular parasites. Among these are the pathogens that cause malaria and toxoplasmosis. The point of attack for this promising substance is the protein tubulin: It helps cells divide and therefore is essential for the multiplication of the...
