A trio of papers provide new insight into the composition and evolution of the surface of Venus, hidden beneath its caustic, high temperature atmosphere. Utilizing imaging from orbit using multiple wavelengths—six-band spectroscopy proposed as part of the VERITAS and EnVision missions—scientists can map the iron content of the Venusian surface and construct the first-ever geologic map.

The Milky Way houses 8,292 recently discovered stellar streams—all named Theia. But Theia 456 is special.

A team of scientists from Osaka University, the University of Queensland and the National University of Singapore's Faculty of Engineering used tiny nanodiamonds coated with a heat-releasing polymer to probe the thermal properties of cells. When irradiated with light from a laser, the sensors acted both as heaters and thermometers, allowing the thermal conductivity of the interior of a cell to be...

Did you know that in microgravity we are preparing one of the most promising fuels for the future?

While losses vary by sector, by region and by industry, data and information from this report may help businesses and communities assess losses and inform long-term recovery and resilience strategies.

Scientists studying the body's natural defenses against bacterial infection have identified a nutrient—taurine—that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could aid efforts seeking alternatives to antibiotics.

A refractive index of zero induces a wave vector with zero amplitude and undefined direction. Therefore, light propagating inside a zero-index medium does not accumulate any spatial phase advance, resulting in perfect spatial coherence. Such coherence brings several potential applications, including arbitrarily shaped waveguides, phase-mismatch-free nonlinear propagation, large-area single-mode...

Plant pathologists working at universities across 26 corn-producing states in the United States and in Ontario, Canada, compiled data about annual corn reductions caused by diseases. Estimated loss from each disease varied greatly by region.

Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process—and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But what if one could convince the unengaged parts of a catalyst to get involved? Chemical reactions...

The Gulf of Mexico holds huge untapped offshore oil deposits that could help power the U.S. for decades.

A lonely rhinoceros at a Bangladesh zoo is looking for new love after losing her partner seven years ago, but pandemic travel restrictions are hampering her keeper's attempts to play matchmaker.

For most people, the word "vampire" brings to mind Dracula or perhaps slayers such as Blade or Buffy; or maybe even the vampire bats of South America. Few will think of a small and rather lovely bird—the finch.

Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll Warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean...

On Jan. 6, the world witnessed how language can incite violence.

Tiny worms that live inside fig trees use the fig wasp as a 'vehicle' to hitch rides from one tree to another by crawling into the wasp's gut without harming it. This relationship has existed for millions of years. But how do these worms‒called nematodes‒choose their wasp vehicles? What cues do they use to check for co-passengers? A new study from the Centre for Ecological Sciences (CES) at...

"Buy low and sell high" says the old adage about investing in the stock market.

Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids is being self-bound in free space in the form of droplets. Understanding from a microscopic perspective how a liquid is formed by adding particles one...

The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil's Atlantic Rainforest, they prefer the fruit of the jussara palm Euterpe edulis.

The strongest climate fluctuation on time scales of a few years is the so-called El Niño phenomenon, which originates in the Pacific. A similar circulation pattern exists in the Atlantic, which scientists under the leadership of GEOMAR Helmholtz Centre for Ocean Research Kiel have studied in more detail. Their results, now published in the international journal Nature Communications, contribute...

Over the last half-century, the probability of heat extreme events has changed by orders of magnitude in almost every region of the world, with occurrences that are now up to a hundred times more in respect to a century ago. Of all-natural disasters, extreme high temperature events are the main cause of weather-related mortality and they are also expected to be the main factor responsible for...

A team of researchers lead by the University of Tsukuba have created a new theoretical model to understand the spread of vibrations through disordered materials, such as glass. They found that as the degree of disorder increased, sound waves traveled less and less like ballistic particles, and instead began diffusing incoherently. This work may lead to new heat- and shatter-resistant glass for...

Scientists at the Institute of Physics of the University of Tartu have found a way to develop optical quantum computers of a new type. Central to the discovery are rare earth ions that have certain characteristics and can act as quantum bits. These would give quantum computers ultrafast computation speed and better reliability compared to earlier solutions. The University of Tartu researchers...

A new study, led by a theoretical physicist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Divergences between scientific and indigenous and local knowledge can provide a better understanding of why local pastoralists may be willing, or not, to participate in conservation initiatives for carnivores, a study from University of Helsinki suggests.

Researchers from Kumamoto University (Japan) have found an Edo period document that clearly indicates the Hosokawa clan, rulers of the Kokura Domain (modern-day Fukuoka Prefecture), completely stopped producing wine in 1632, the year before the shogunate ordered them to move to the Higo Domain (now Kumamoto Prefecture). The researchers believe that the discontinuation of wine production was...

Mitochondria are vital for the human body as cellular powerhouses: They possess more than 1000 different proteins, required for many central metabolic pathways. Dysfunction of these lead to severe diseases, especially of the nervous system and the heart. In order to transport proteins and metabolites, mitochondria contain a special group of so-called beta-barrel membrane proteins, which form...
