Scientists have identified the sensor in human lungs that detects SARS-CoV-2 and signals that it's time to mount an antiviral response.
A new study suggests more than half of doctors, nurses, and emergency responders involved in COVID-19 care could be at risk for one or more mental health problems, including acute traumatic stress, depression, anxiety, problematic alcohol use, and insomnia. The researchers found that the risk of these mental health conditions was comparable to rates observed during natural disasters, such as 9/11...
Most consumers of drinking water in the United States know that chemicals are used in the treatment processes to ensure the water is safe to drink. But they might not know that the use of some of these chemicals, such as chlorine, can also lead to the formation of unregulated toxic byproducts.
Yellowstone National Park's Old Faithful geyser regularly blasts a jet of boiling water high in the air. Now, an international team of astronomers has discovered a cosmic equivalent, a distant galaxy that erupts roughly every 114 days.

A team of astronomers led by the University of Arizona has observed a luminous quasar 13.03 billion light-years from Earth—the most distant quasar discovered to date. Dating back to 670 million years after the Big Bang, when the universe was only 5% its current age, the quasar hosts a supermassive black hole equivalent to the combined mass of 1.6 billion suns.
One-third of the fertilizer applied to grow corn in the U.S. each year simply compensates for the ongoing loss of soil fertility, leading to more than a half-billion dollars in extra costs to U.S. farmers every year, finds new research from the University of Colorado Boulder published last month in Earth's Future.
Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds. Bee pollination, however, involves an inherent conflict of interest, because bees are only interested in pollen as a food source.
Households in Europe and North America are flooding the oceans with plastic pollution simply by washing their clothes, scientists said Tuesday after research found the majority of microplastics in Arctic seawater were polyester fibres.
The International Space Station bid adieu Tuesday to 12 bottles of French Bordeaux wine and hundreds of snippets of grapevines that spent a year orbiting the world in the name of science.
Every field has its underlying principles. For economics it's the rational actor; biology has the theory of evolution; modern geology rests on the bedrock of plate tectonics.
Researchers have developed a new laser-based process for 3-D printing intricate parts made of glass. With further development, the new method could be useful for making complex optics for vision, imaging, illumination or laser-based applications.
Family courts are misunderstanding and misusing research around how children form close relationships with their caregivers, say an international group of experts.
According to the doctoral thesis of Federica Polo at the University of Vaasa, to successfully keep up with changes in the business environment, companies need to focus on the process that leads people to accept and adapt to change, encouraging them to bring their added value to the organization.
To resolve the energy crisis and environmental issues, research to move away from fossil fuels and convert to eco-friendly and sustainable hydrogen energy is well underway around the world. Recently, a team of researchers at POSTECH has proposed a way to efficiently produce hydrogen fuel via water-electrolysis using inexpensive and readily available nickel as an electrocatalyst, greenlighting the...
Groundwater flow and seepage can form large gullies along coastal cliffs in the matter of days, it has been discovered, as per a recently-published paper.
Entomologist Akito Kawahara's message is straightforward: We can't live without insects. They're in trouble. And there's something all of us can do to help.
Rolls-Royce and UK Space Agency hope to ‘revolutionise space travel’ with deal to build nuclear propulsion engines British spacecraft could travel to Mars in half the time it now takes by using nuclear propulsion engines built by Rolls-Royce under a new deal with the UK Space Agency.The aerospace company hopes nuclear-powered engines could help astronauts make it to Mars in three to four...
Silicon carbide (SiC), a versatile and resistant material that exists in multiple crystalline forms, has attracted much attention thanks to its unique electronic properties. From its use in the first LED devices, to its applications in high-voltage devices with low power losses, SiC displays exceptional semiconductor behavior. So far, the operating voltages for unipolar SiC devices are below 3.3...
Scientists are combining artificial intelligence and advanced computer technology with biological know how to identify insects with supernatural speed. This opens up new possibilities for describing unknown species and for tracking the life of insects across space and time
It's been more than a year since the first cases were identified in China, yet the exact origins of the COVID-19 pandemic remain a mystery. Though strong evidence suggests that the responsible coronavirus originated in bats, how and when it crossed from wildlife into humans is unknown.
Climate change prompts many important questions, not least how it affects animals and plants: Do they adapts, gradually migrate to different areas or become extinct? And what is the role played by human activities? This applies not least to Greenland and the rest of the Artic, which are expected to face the greatest effects of climate changes.
Curtin University researchers have used ancient crystals from eroded rocks found in stream sediments in Greenland to successfully test the theory that portions of Earth's ancient crust acted as 'seeds' from which later generations of crust grew.
Remarkably well-preserved fossils are helping scientists unravel a mystery about the origins of early animals that puzzled Charles Darwin.
