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.
A new study shows that in China, wearing masks for health reasons tends to influence people to follow rules and norms more generally.
Robotics and wearable devices might soon get a little smarter with the addition of a stretchy, wearable synaptic transistor. The device works like neurons in the brain to send signals to some cells and inhibit others in order to enhance and weaken the devices' memories.
A new study provides a novel framework for identifying broad coral disease resistance traits and examines the fundamental processes behind species survival.
Researchers have developed a new satellite tag that allows them to better track whales' behavior, including previously unobservable feeding events during dives.

New research has discovered that monkeys with the most human interactions, typically around sources of food, may act as 'superspreaders' of human respiratory diseases. The study found that locations with access to human-provisioned food see monkeys from different groups coming together and mixing closely, leading to larger outbreaks of zooanthroponotic diseases.
A study has used a multidisciplinary high-throughput functional genomics approach to identify and functionally validate dozens of genes that could cause or protect against Parkinson's disease.
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."
The sun is literally bursting with activity, which bodes well for those hoping to see the northern lights, particularly in the coming...
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.
A new study finds enhanced activity of a specific enzyme drives spinocerebellar ataxia type 14, which suggests inhibiting the enzyme may have therapeutic potential.
The world's whitest paint is now thinner and lighter than ever before. This makes it ideal for cooling vehicles like airplanes or cars, which reduces the reliance on air conditioning.
Forecasters are predicting a 'three-peat La Niña' this year. A recent study of ocean temperature patterns suggests that climate change could, in the short term, be favoring La Niñas. A La Niña winter tends to be cooler and wetter in the Pacific Northwest and hotter and drier in the U.S. Southwest. Other worldwide effects include drier conditions in East Africa, and rainier weather in Australia,...
Using data from the Pennsylvania Overdose Information Network from the years 2018-20 and American Community Survey data from 2015-19, geography researchers looked at the prevalence of overdoses in the state and found the availability of the anti-overdose therapeutic naloxone to be a key factor in overdose survival.
Chemists have uncovered a mechanism for peptide-forming reactions to occur in water -- something that has puzzled scientists for decades.
Researchers have found that eddies at the edges of subtropical ocean gyres deliver nutrients that sustain the phytoplankton within the gyres. The findings answer a longstanding question about how these microbes are able to survive.

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.
When public health specialist Rick Bright launched the Pandemic Prevention Institute (PPI) under the aegis of the Rockefeller Foundation last year, he recognized that several other efforts—some old, some new—had similarly ambitious visions for how to make the world safer from pathogens. “No one can do it all,” Bright told Science in October 2021, when...
Nearly 2500 years ago, two armies clashed outside the walls of Himera, a Greek colony on the northern coast of Sicily. Greek forces from Himera and the neighboring colonies of Agrigento and Syracuse battled their great rivals, the Carthaginians, who hailed from the African coast of the Mediterranean. Fighting raged across the city’s western necropolis, fallen warriors toppling among the...
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.
