A massive collaborative research project offers projections to the year 2100 of future sea-level rise from all sources of land ice, offering the most complete projections created to date.

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.

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.

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 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.

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...

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...

The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a new study.

A new study details the earliest modern human burial in Africa. The remains of a 2.5 to 3 year-old child were found in a flexed position, deliberately buried in a shallow grave directly under the sheltered overhang of the cave. The interment at Panga ya Saidi joins increasing evidence of early complex social behaviors in Homo sapiens.

Studies have shown that while CBD reduces pain sensation in animals, its ability to do so in humans is limited by low bioavailability, the extent to which the drug successfully reaches its site of action. Now, new research suggests this obstacle may be overcome by a novel CBD analog known as KLS-13019.

Larger bumblebees are more likely to go out foraging in the low light of dawn, new research shows.

A count of the Western Monarch butterfly population last winter saw a staggering drop in numbers, but there are hopeful signs the beautiful pollinators are adapting to a changing climate and ecology.

Astronomers examined a massive star two-and-a-half years before it exploded into a supernova. At the end of their lives, cool, yellow stars are typically shrouded in hydrogen, which conceals the star's hot, blue interior. But this yellow star, located 35 million light-years from Earth in the Virgo galaxy cluster, was mysteriously lacking this crucial hydrogen layer at the time of its explosion.

New research demonstrates that noninvasive neuromodulation via low-intensity ultrasound can have cell-type selectivity in manipulating neurons.

When light hits certain molecules, it dislodges electrons that then move from one location to another, creating areas of positive and negative charge. This 'charge transfer' is highly important in many areas of chemistry, photosynthesis and semiconductor devices and solar cells. A new study reveals how a molecule's structure changes as charge is redistributed, with some chemical bonds getting...
