By studying impact marks on the surface of asteroid Bennu—the target of NASA's OSIRIS-REx mission—a team of researchers led by the University of Arizona has uncovered the asteroid's past and revealed that despite forming hundreds of millions of years ago, Bennu wandered into Earth's neighborhood only very recently.
In ecosystems around the globe, the danger of being a common or widespread species is the tendency to be overlooked by conservation efforts that prioritize rarity.
Australian bees are known for pollinating plants on beautiful sunny days, but a new study has identified two species that have adapted their vision for night-time conditions for the first time.
A study published today in the journal Science Advances has revealed that the United States ranks as high as third among countries contributing to coastal plastic pollution when taking into account its scrap plastic exports as well as the latest figures on illegal dumping and littering in the country. The new research challenges the once-held assumption that the United States is adequately...
Tiny, seemingly harmless ocean plants survived the darkness of the asteroid strike that killed the dinosaurs by learning a ghoulish behavior—eating other living creatures.
Specially-adapted drones developed by a UCL-led international team have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions.
When atoms get extremely close, they develop intriguing interactions that could be harnessed to create new generations of computing and other technologies. These interactions in the realm of quantum physics have proven difficult to study experimentally due the basic limitations of optical microscopes.
The company seeking to develop Pebble Mine in the headwaters of Bristol Bay has long promised that the controversial project would bring Alaska jobs, economic growth and tax revenue.
The uncertainty and confusion caused by the COVID-19 pandemic is being "widely exploited by terror groups for spinning a plethora of sinister schemes", which could lead to a new tide of violence against people and governments.
Subarctic regions are facing rapid changes in climate and land-use intensity. An international research team recently completed an investigation to see how these changes are affecting the food webs and fish communities of lakes in northern Finland. Biomasses and omega-3 fatty acids, EPA and DHA, were determined from the algal producers at the base of food web to large carnivorous fish from 20...
Optical barcodes enable detection and tracking via unique spectral fingerprints. They've been widely applied in areas ranging from multiplexed bioassays and cell tagging to anticounterfeiting and security. Yu-Cheng Chen of the Bio+Intelligent Photonics Laboratory at Nanyang Technological University notes that the concept of optical barcodes typically refers to a fixed spectral pattern...
Let's call it the Texas two-step, but for molecules.
Not far from Santa Catalina Island, in an ocean shared by divers and fishermen, kelp forests and whales, David Valentine decoded unusual signals underwater that gave him chills.
A new study using data from NASA's Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy? The target of the new study, as reported in our press release, is Barnard's Star, which is one of the closest stars to Earth at a distance of just 6 light years. Barnard's Star is a...
A new study reveals that the Chicxulub impact crater and its hydrothermal system hosted a subterranean ecosystem that could provide a glimpse of Earth's primordial life.
Sometimes insects show signs of monster behavior.
Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
All 1200 islands that make up the Republic of Maldives are featured in this spectacular image captured by the Copernicus Sentinel-3 mission.
This November the newest member of the EU's Copernicus program, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA's former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed.
Emiliano Bruner, a paleoneurologist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), in collaboration with Marlize Lombard, of the University of Johannesburg, has just published a study in the Journal of Anthropological Sciences which describes the braincase traits of Florisbad, a fossil found in South Africa in 1932, and its similarities with other species like Homo...
Burnt orange daytime skies signal that the consequences of climate change are already here. But while we tend to focus on the death and destruction resulting from the growing frequency and severity of wildfires and other disasters, we often pay less heed to the ways their costs ricochet through the financial system, with the potential for widespread collateral damage.
Polypropylene (PP) is one of the most widely used plastics in the world. By controlling the spatial orientation of the propylene building blocks and additional polar components, it should be possible to create a new generation of attractive, engineered, specialty plastics, with improved wettability or enhanced degradability, based on PP. In the journal Angewandte Chemie, Japanese scientists have...
At first glance, a pack of wolves has little to do with a vinaigrette. However, a team led by Ramin Golestanian, Director at the Max Planck Institute for Dynamics and Self-Organization, has developed a model that establishes a link between the movement of predators and prey and the segregation of vinegar and oil. They expanded a theoretical framework that until now was only valid for inanimate...
The Kingdom of Saudi Arabia (KSA) is at a crossroads. Recent long-term studies of the area indicate that rising temperatures and evaporation rates will likely further deplete scarce water resources critical to meeting the nation's agricultural, industrial, and domestic needs; more extreme flooding events could endanger lives, economic vitality, and infrastructure; and a combination of increasing...
