There's a new metric that provides a more holistic look at how much water is stored in snowpack, and for how long.

Research has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called 'noise,' or probabilistic elements.

Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.

Scientists tested several hypotheses on the drivers of social aging in free-living Assamese macaques in Thailand. The researchers collected data on the social behavior of females for eight years and found that the size of their social networks decreases with increasing age. The females continued to interact with their close social partners, but gradually withdrew from social interactions altogether. The results contribute to the understanding of the evolutionary origins of social aging.

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

Events in the stratosphere are making long-range weather in Northern Europe easier to forecast, researchers have discovered.

Physicists achieve major leap in precision and accuracy at extremely low light levels.

A rigorous analysis of numerous studies concludes that a part of the brain traditionally associated with movement is abnormal in children with developmental language impairments. The discovery has the potential to improve both the diagnosis and treatment of the language difficulties.

Researchers have created a DNA origami platform called DoriVac, whose core component is a self-assembling square block-shaped nanostructure. DoriVac vaccines enabled tumor-bearing mice to better control the growth of tumors and to survive significantly longer than control mice.

Researchers show that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.

In order to limit the increase in global average temperature to 1.5 C, it is essential to drastically reduce carbon dioxide emissions in the atmosphere. This would mean not exploiting most of the existing coal, conventional gas and oil energy resources in regions around the world, according to new research. The study presents the atlas of unburnable oil in the world, a world map designed with environmental and social criteria that warns which oil resources should not be exploited to meet the commitments...

Making a personalized T cell therapy for cancer patients currently takes at least six months. Scientists have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.

Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.

A serious immune deficiency in newborns may originate from a system that protects the fetus in utero but lingers too long after birth.

Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.

Researchers have discovered a new class of plasma oscillations -- the back-and-forth, wave-like movement of electrons and ions. The research paves the way for improved particle accelerators and commercial fusion energy.

Hunger can drive a motivational state that leads an animal to a successful pursuit of a goal -- foraging for and finding food. In a highly novel study, researchers describe how two major neuronal subpopulations in a part of the brain's thalamus called the paraventricular nucleus participate in the dynamic regulation of goal pursuits. This research provides insight into the mechanisms by which the brain tracks motivational states to shape instrumental actions.

Automated insulin dosing systems combine low-cost blood-glucose monitors with insulin pumps that use precision dosing to continuously regulate blood-sugar and hold it steady. Synthetic biologists have found a way to piggyback on the technology and make it universally applicable for the precision dosing of virtually any drug.

A new study provides groundbreaking findings that offer insights on the migration and foraging patterns of leatherback sea turtles along the Northwest Atlantic shelf.

Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.

Managing circadian rhythms through intense light and chronologically timed therapy can help prevent or treat a variety of circulatory system conditions including heart disease, according to a new study.

Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate change.
