Researchers have identified three existing drugs with the potential to clear SARS-CoV-2 infections.
Two dentists debunk 14 of the most common myths about teeth. They discuss cavities, electric toothbrushes, charcoal toothpaste, and...
A pioneering technique that captures precisely how mountains bend to the will of raindrops has helped to solve a long-standing scientific enigma.
Droplets of fat inside our cells are helping the body's own defence system fight back against infection, University of Queensland researchers have discovered.
A new system developed by chemical engineers at MIT could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.
Sea floor sediments of the Arctic Ocean can help scientists understand how permafrost responds to climate warming. A multidisciplinary team from Stockholm University has found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings, published in Science Advances, caution about what could happen in the near future: That Arctic warming by only...
It's widely known that thick, viscous liquids—like honey—flow more slowly than low-viscosity liquids, like water. Researchers were surprised to find this behavior flipped on its head when the liquids flow through chemically coated capillaries. In fact, through these specially coated tubes, liquids a thousand times more viscous flow ten times faster.
With demand for lentils growing globally and climate change driving temperatures higher, a University of Saskatchewan-led international research team has developed a model for predicting which varieties of the pulse crop are most likely to thrive in new production environments.
A team of researchers have examined whether urban red maples—a resilient native tree known to thrive in urban environments—acclimate to environmental shifts and whether that response is impacted by the size of the city.
Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that pump drugs out of the cell, rendering the chemotherapies ineffective. Now, researchers reporting in ACS' Nano Letters have developed nanoparticles that release bursts of...
Allegiance and loyalty to your country is highly valued in America, but what if you feel America doesn't love you back? New research examined whether feeling like you belong in America—or not—affected how members of different races and ethnicities participated in politics.
Scientists from NASA's Goddard Space Flight Center in Greenbelt, Maryland, and international collaborators demonstrated a new method for mapping the location and size of trees growing outside of forests, discovering billions of trees in arid and semi-arid regions and laying the groundwork for more accurate global measurement of carbon storage on land.
Launching soon from the California coast, the satellite will track sea levels worldwide. A new video series introduces some of the NASA JPL scientists and engineers involved in the mission. Meet the People Behind the Sentinel-6 Michael Freilich Spacecraft Video...
It is estimated that only 1% of bacteria are pathogenic for humans or animals. Among them, the bacterial genus Listeria has been widely studied as it contains two species, Listeria monocytogenes and Listeria ivanovii, which are pathogenic, causing the disease known as listeriosis. Until now, the genus Listeria consisted of a total of 20 species. Researchers from the CEU Cardenal Herrera University...
A virtual conference was thrown into confusion when the platform hosting the event came with a pre-packaged ‘naughty word’ censor Participants in a virtual paleontology session found themselves caught between a rock and a hard place last week, when a profanity filter prevented them from using certain words – such as bone, pubic, stream and, er, beaver – during an online conference.The...
Multidrug resistance (MDR) -- a process in which tumors become resistant to multiple medicines -- is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that pump drugs out of the cell, rendering the chemotherapies ineffective. Now, researchers have developed nanoparticles that release bursts of calcium inside tumor cells,...
A new method for mapping the location and size of trees growing outside of forests helped scientists discover billions of trees in arid and semi-arid regions and lays the groundwork for more accurate global measurement of carbon storage on land.
Thinking back on a time you encountered false information or 'fake news' may prime your brain to better recall truthful memories.
Eros, the fabled Greek god of love, was said to bring confusion and weaken the mind. New research, however, suggests that young adults are instead quite rational when it comes to selecting potential sexual partners.
In paddy fields, water management creates long-term anaerobic conditions in which soil organic carbon (SOC) mineralisation is largely coupled with redox processes. Iron oxides are one of the main minerals in paddy soils, and over 80% of soil anaerobic respiration depends on iron reduction.
When NASA's OSIRIS-REx spacecraft descends toward the surface of Bennu on Oct. 20, it will be the first time that a U.S.-led mission attempts to pick up a sample of pristine material from an asteroid. Bennu is likely an extraterrestrial accumulation of the original leftovers from the formation of our solar system.
Natural diamonds can form through low pressure and temperature geological processes on Earth, as stated in an article published in the journal Geochemical Perspectives Letters. The newfound mechanism, far from the classic view on the formation of diamonds under ultra-high pressure, is confirmed in the study, which draws on the participation of experts from the Mineral Resources Research Group of...
A peer-reviewed study by scientists at the Environmental Working Group estimates that more than 200 million Americans could have the toxic fluorinated chemicals known as PFAS in their drinking water at a concentration of 1 part per trillion, or ppt, or higher. Independent scientific studies have recommended a safe level for PFAS in drinking water of 1 ppt, a standard that is endorsed by EWG.
Emiliano Bruner, a paleoneurologist at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has coordinated a study published recently in the journal Archaeological and Anthropological Sciences, on the ergonomic relationship between hand and Lower Paleolithic stone tools, in particular for choppers and handaxes.
Children's television programming not only shapes opinions and preferences, its characters can have positive or negative impacts on childhood aspiration, says a new study from Michigan State University.
