Sea ice cover in the Southern Hemisphere is extremely variable, from summer to winter and from millennium to millennium, according to a new study. Overall, sea ice has been on the rise for about 10,000 years, but with some exceptions to this trend. Researchers uncovered these findings by examining the chemistry of a 54,000-year-old South Pole ice core.
A multidisciplinary team of researchers has recognized the soldiers of the last battles of the siege of Rennes in 1491. These are the only witnesses of the forces involved in the conflict between the armies of Duchess Anne of Brittany and the King of France.
By discovering a potential new cellular mechanism for migraines, researchers may have also found a new way to treat chronic migraine.
Ring microlasers are eyed as potential light sources for photonic applications, but they first must be made more powerful. Combining multiple microlasers into an array solves only half of the problem, as this adds noisy 'modes' to the resulting laser light. Now, thanks to the math behind supersymmetry theory, engineers have achieved single-mode lasing from such an array. By calculating the...
Researchers across the dark matter community that have begun to wonder if they are looking for the right type of dark matter. They have proposed a new way to look for the particles that might make up dark matter by repurposing existing tabletop sensor technology.
Mastery of fire has given humans dominance over the natural world. A new study provides evidence of ancient humans significantly altering entire ecosystems with flames.
Researchers have created a probe that glows when it detects an enzyme associated with issues that can lead to blood clots and strokes.
Last year, researchers used a mouse model that included immune-reactive T cells from patients with Crohn's disease in a proof-of-principle demonstration that a flagellin-directed immunotherapy might provide similar benefits in patients. Now they have moved a step closer to possible clinical testing of this treatment, with a study that describes IgG antibodies in Crohn's disease specific for...
A rare and unusual newly discovered ant from Ecuador has been named Strumigenys ayersthey, with the suffix '-they' chosen in contrast to traditional naming practices which, to date, fail to recognize gender diversity formally. The new species is distinguished by its predominantly smooth and shining cuticle surface and long trap-jaw mandibles.
A previously underappreciated part of the body's natural defense against SARS-CoV-2, called non-RBD-directed antibodies, actually plays a major role in combating the virus, according to a new study. That's good news for scientists designing the next generation of vaccines to protect against variants of the virus or future emerging coronaviruses.
Biodiversity is of crucial importance to the marine ecosystem. The prohibition of trawling activities in the Hong Kong marine environment for two and a half years has significantly improved biodiversity, a new study has found. Research results showed that the trawl ban could restore and conserve biodiversity in tropical coastal waters.
A protein called Sir2 may facilitate C. albicans' transition from ovoid yeast to thread-like hypha. C. albicans cells that were missing the Sir2 gene were less likely to form true hyphae in lab experiments than cells of the same species that had that gene.
New simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field.
The incorporation of boron into polycyclic aromatic hydrocarbon systems leads to interesting chromophoric and fluorescing materials for optoelectronics, including organic light-emitting diodes (OLEDS) and field-effect transistors, as well as polymer-based sensors. A research team has now introduced a new anionic organoborane compound. Synthesis of the borafluorene succeeded through the use of...
Proteins perform a vast array of functions in the cell of every living organism with critical roles in biological processes. There are numerous chemical switches that control the structure and the function of proteins, which were thought to be well understood: so a team of researchers were surprised to discover a completely new on/off switch that seems to be a ubiquitous regulatory element in...
Biologists find cell extrusion, a process that helps organisms eliminated unneeded cells, is triggered when cells can't replicate their DNA during cell division. In humans, extrusion may serve as a way for the body to eliminate cancerous or precancerous cells.
Stem cells have the ability to turn into different types of cell. Now scientists have developed a method to organize lab-grown stem cells into an accurate model of the first stage of human embryo development.
Engineers have created an environmentally friendly leather alternative made from silk. The material can be printed into different patterns and textures, has similar physical properties to real leather, and can withstand the folding, piercing, and stretching typically used to create leather goods.
Subtle differences in the shape of the brain that are present in adolescence are associated with the development of psychosis, according to an international team. The 'sobering' results were made using the largest study to date of brain scans in adolescents at risk for psychosis.
Researchers analyze more palatable alternatives to the kind of social distancing mandates that threw a wrench at how businesses, schools and even family gatherings work.
Many people with diabetes endure multiple, painful finger pricks each day to measure their blood glucose. Now, researchers have developed a device that can measure glucose in sweat with the touch of a fingertip, and then a personalized algorithm provides an accurate estimate of blood glucose levels.
Researchers have found that mice can sense extremely fast and subtle changes in the structure of odors and use this to guide their behavior. The findings alter the current view on how odors are detected and processed in the mammalian brain.
A new, high-quality bonobo genome assembly has been constructed. It is allowing scientists to more accurately compare the bonobo genome to that of other great apes - the gorilla, orangutan, chimpanzee - and to the modern human. This analysis is revealing new information about hominid evolution, distinctions between chimps and bonobos and genetic relations among present-day hominids, and predicts a...
Clothing, from tank tops to parkas, helps people adapt to temperatures outdoors. But you can only put on or take off so much of it, and fluctuations in weather can render what you are wearing entirely inadequate. Researchers now describe a high-tech alternative: a reversible textile they designed to trap warmth in the cold and reflect it during hot weather, all while generating small amounts of...
