By analyzing the occurrences of exposed dusty ice on Mars using data from NASA's Mars Reconnaissance Orbiter, ASU planetary scientists Aditya Khuller and Philip Christensen have found the lowest latitude detection of dusty water ice on Mars.

City trees are important: they purify the air, reduce heat islands, help regulate the water cycle and provide immense health benefits. Yet unbridled development threatens the survival of the urban forest and the full range of ecosystem services it provides.

The COVID-19 pandemic has seen many in key roles—such as doctors, nurses, police officers and teachers—working tirelessly, going well beyond their contracts to keep things running.

In 2020, the pandemic has made homeschooling a fact of life. Even before this, though, what was once the obscure choice of a few families has grown in popularity over the past decade. In 2019, the Children's Commissioner for England estimated that around 60,000 children were homeschooled.

A 7.1 magnitude earthquake was recorded off the coast of Fukushima Prefecture in northeastern Japan on Saturday night, injuring around 100 people, closing roads and trains, and leaving almost a million people without electricity overnight.

Wasps provide crucial support to their extended families by babysitting at neighboring nests, according to new research by a team of biologists from the universities of Bristol, Exeter and UCL published today in Nature Ecology and Evolution.

Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can suppress electrical conductivity, a study led by physicists at the University of California, Riverside, has found.

Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a single quantum bit in a dense cloud.

Much of the United States was in the icy grip of an "unprecedented" winter storm on Monday as frigid Arctic air sent temperatures plunging, forcing hundreds of flight cancellations, making driving hazardous and leaving millions without power in Texas.

Every year, billions of songbirds migrate thousands of miles between Europe and Africa—and then repeat that same journey again, year after year, to nest in exactly the same place that they chose on their first great journey.

As Brazil reels from the impact of COVID-19, a "profound cultural change" is needed to stop women bearing the brunt of the crisis, says the head of biomedical research institute Fiocruz.

Researchers around the world are searching for new synthetic materials with special properties like superconductivity—that is, the conduction of electric current without resistance. These new substances are an important step in the development of highly energy-efficient electronics. The starting material is often a single-layer honeycomb structure of carbon atoms (graphene).

UConn astrophysicist Chiara Mingarelli is part of a team of researchers who recently published data on a hint of a signal that sent ripples of excitement through the physics community. These monumental findings are the culmination of 12 and a half years of data gathered from NANOGrav—a network of pulsars across the galaxy—all in the hopes of detecting gravitational waves.

Researchers from North Carolina State University, Boston University and Kraton Corporation have demonstrated a family of self-sterilizing polymers that are effective at inactivating coronaviruses, including SARS-CoV-2—the virus that causes COVID-19. The work opens the door to a suite of applications that could help to reduce the transmission of COVID-19 and other diseases.

New research has revealed that women in India have suffered much more than men during the coronavirus pandemic, and in more ways than is usually recognised, due to pre-existing gender inequalities.

Gay men are more likely than lesbian women to face stigma and avoidant prejudice from their heterosexual peers due to the sound of their voice, a new study in the British Journal of Social Psychology reports. Researchers also found that gay men who believe they sound gay anticipate stigma and are more vigilant regarding the reactions of others.

Where do you see yourself in five years? It's a standard job interview question, but it's an even better question to ask yourself about your relationship.

Researchers at the Francis Crick Institute have compared the original SARS-CoV-2 spike protein with a mutated version which arose last spring. They have found structural differences which could help to explain why the mutated version remains the dominant form circulating in all recent variants of concern, such as the UK and South African strains.

One of the big contributors to climate change is right beneath your feet, and transforming it could be a powerful solution for keeping greenhouse gases out of the atmosphere.

There's a useful concept from psychology that helps explain why good people do things that harm the environment: the false consensus effect. That's where we overestimate how acceptable and prevalent our own behavior is in society.

COVID-19 has brought an unprecedented crisis to universities around the world. But female academics in Indonesian universities are facing additional constraints.

Feathers are a sleek, intricate evolutionary innovation that makes flight possible for birds, but in addition to their stiff, aerodynamic feathers used for flight, birds also keep a layer of soft, fluffy down feathers between their bodies and their outermost feathers to regulate body temperature.

Unique electronic structures found at materials interfaces can allow unconventional quantum states to emerge. In a new report on Science, Changjiang Liu and a research team at the Argonne National Laboratory, University of Illinois and the Chinese Academy of Sciences detailed the discovery of superconductivity in electron gases formed at the interfaces between potassium tantalate (KTaO3) and insulating overlayers of either Europium-II oxide (EUO) or lanthanum aluminate (LaAlO3). The superconducting... Читать дальше...

When the universe was about 350 million years old it was dark: there were no stars or galaxies, only neutral gas—mainly hydrogen—the residue of the Big Bang. That foggy period began to clear as atoms clumped together to form the first stars and the first quasars, causing the gas to ionize and high-energy photons to travel freely through space.

Researchers from the Faculty of Biological Sciences of the University of Valencia (UV), with other Spanish and European universities, have identified a total of 98 species of bees potentially pollinating three crops of economic importance in Spain: melon, watermelon and almond. The research, published in the journal Annales de la Société entomologique de France, will help plan conservation actions for the pollinating diversity of these crops.
