A physicist at the University of California, Riverside, and her former graduate student have successfully modeled the formation of SARS-CoV-2, the virus that spreads COVID-19, for the first time.

NASA's Double Asteroid Redirection Test (DART) spacecraft intentionally crashed into Dimorphos, the asteroid moonlet in the double-asteroid system of Didymos, on Monday, 26 September 2022. This was the first planetary defense test in which an impact of a spacecraft attempted to modify the orbit of an asteroid.
Hurricanes have become prolific at producing damaging winds and storm surge. FIU research shows they have also grown to become prolific at making more rain.
Neutron scattering is considered the method of choice for investigating magnetic structures and excitations in quantum materials. Now, for the first time, the evaluation of measurement data from the 2000s with new methods has provided much deeper insights into a model system—the 1D Heisenberg spin chains. A new toolbox for elucidating future quantum materials has been achieved.
The sun emitted a strong solar flare that peaked at 4:25 p.m. EDT on Oct. 2, 2022. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.
Oregon State University researchers have developed a new satellite tag that allows them to better track whales' behavior, including previously unobservable feeding events during dives.
A new study in Science Advances led by researchers at The University of Texas at Arlington provides a novel framework for identifying broad coral disease resistance traits and examines the fundamental processes behind species survival.
New research has mapped how infectious diseases spread among wildlife populations in areas where humans and wildlife live in close proximity. The study has identified the animals, specifically wild monkeys that live in large groups alongside human settlements, that may act as "superspreaders."
Phonetic convergence, or phonetic imitation, is a form of speech production in which a talker's speech becomes similar to that of the person with whom they are speaking. In a recent article published in the journal Speech Communication, researchers studied whether and how people working together begin to sound more like each other as they work.
Stanford University researchers have discovered a rapid and sustainable way to synthetically produce a promising cancer-fighting compound right in the lab. The compound's availability has been limited because its only currently known natural source is a single plant species that grows solely in a small rainforest region of Northeastern Australia.
We tend to eat, drink, and move less when we're feeling under the weather. And we're not alone—most animals reduce those same three behaviors when they're fighting an infection.
Some 250 million years ago—long before dinosaurs roamed the earth—global warming and acid oceans caused by the rapid volcanic emission of the Siberian Traps led to the Permian-Triassic mass extinction, which resulted in the elimination of over 95% of marine and 70% of terrestrial life.
Forecasters are predicting a "three-peat La Niña" this year. This will be the third winter in a row that the Pacific Ocean has been in a La Niña cycle, something that's happened only twice before in records going back to 1950.
The world's whitest paint—seen in this year's edition of Guinness World Records and "The Late Show With Stephen Colbert"—keeps surfaces so cool that it could reduce the need for air conditioning. Now the Purdue University researchers who created the paint have developed a new formulation that is thinner and lighter—ideal for radiating heat away from cars, trains and airplanes.
Purdue University chemists have uncovered a mechanism for peptide-forming reactions to occur in water—something that has puzzled scientists for decades.
Scientists have discovered a sexual reproduction process in microalgae that helps them better understand algae and plant evolution. Their discovery could lead to new industrial applications for microalgae, ranging from wastewater treatment to production of food ingredients and pigments.
For the very first time, a study led by Julian Chen and his group in Arizona State University's School of Molecular Sciences and the Biodesign Institute's Center for the Mechanism of Evolution, has discovered an unprecedented pathway producing telomerase RNA from a protein-coding messenger RNA (mRNA).
Subtropical gyres are enormous rotating ocean currents that generate sustained circulations in the Earth's subtropical regions just to the north and south of the equator. These gyres are slow-moving whirlpools that circulate within massive basins around the world, gathering up nutrients, organisms, and sometimes trash, as the currents rotate from coast to coast.
While some may have been surprised that the Nobel Prize in Medicine was awarded to a paleogeneticist Monday, researchers say understanding our distant ancestors helps explain modern human health—even when it comes to COVID.
Researchers have shown that 3D laser printing can be used to fabricate a high-quality, complex polymer optical device directly on the end of an optical fiber. This type of micro-optical device—which has details smaller than the diameter of a human hair—could provide an extremely compact and inexpensive way to tailor light beams for a variety of applications.
Close to thirty African penguins have died due to avian flu since mid-August at Boulders beach near Cape Town, a crucial breeding site in South Africa.
Kenya's new president says the Cabinet has "effectively" lifted the country's ban on openly cultivating genetically modified crops, reversing a decade-old decision as the East African country struggles with food security and a deadly drought.
It's a question that follows any natural disaster, especially monster hurricanes like Ian: Was this caused by climate change?
Scientists have made a key breakthrough in the quest to accurately predict fluctuations in the rotation of the Earth and so the length of the day—potentially opening up new predictions for the effects of climate change.
Today, more snow than rain falls in the Arctic, but this is expected to reverse by the end of the century. A new study shows the frequency of rainy days in the Arctic could roughly double by 2100.
