A machine-learning algorithm could provide auto manufacturing, aerospace and other industries a faster and more cost-efficient way to test bulk materials.

An international effort to measure air quality in South Korea, a region with complex sources of pollution, may provide new insights into the atmospheric chemistry that produces ozone pollution, according to a team of scientists.

A research team has discovered that communication between two key memory regions in the brain determines how what we experience becomes part of what we remember, and as these regions mature, the precise ways by which they interact make us better at for…

Researchers created a comprehensive atlas of the types of cells found in the brain cerebrovasculature, which provides oxygen and nutrients to the brain and helps form the blood-brain barrier. They also found significant differences between healthy cell…

A computer modeling study shows how the emissions of the greenhouse gas nitrous oxide have increased from soils over the last century. The newly published research found the expansion of land devoted to agriculture since 1900 and intensive fertilizer i…

African children and adolescents hospitalized with COVID-19 experience much higher mortality rates than Europeans or North Americans of the same age, according to a new study.

Researchers have developed a new scoring system to help health care professionals predict the 30-day mortality risk for patients with alcohol-associated hepatitis, and the tool appears to more accurately identify patients at highest risk of death and t…

Researchers surveyed and compared early- and late-stage breast and colorectal cancer diagnoses in patients in pre-pandemic 2019 and in 2020, the first full year of the COVID-19 pandemic, discovering fewer of the former and more of the latter as patient…

Receiving at least one vaccine dose was associated with statistically significant declines in multiple psychological distress factors, researchers report in a new study.

Temperature fluctuations such as heatwaves can have very different effects on infection rates and disease outcomes depending on the average background temperature, says a new report.

A one-time infusion of stem cells from bone marrow improves the survival of mice with sepsis.

Researchers have discovered that the protein YME1L regulates the production of new nerve cells and the maintenance of neural stem cells in the adult brain. This holds great potential for regenerative treatments after brain injuries and other diseases.

A new description of two well-preserved ancient fossil plant specimens in Washington state is prompting paleobotanists to rethink how plants might have been dispersed during the Late Cretaceous, between 66 and 100 million years ago.

It was a medical mystery: When scientists induced a particular genetic mutation in mouse eggs, the resulting embryos would all die in the womb within a week. And yet, people with the same troublesome gene are thriving.

Researchers have successfully used CRISPR-Cas9 to edit the genomes of the black-legged tick. To accomplish this feat, they developed an embryo injection protocol that overcame a major barrier in the field.

In a new, rare study of direct brain recordings in children and adolescents, scientists have discovered as brains mature, the precise ways by which two key memory regions in the brain communicate make us better at forming lasting memories. The findings…

A modeling study raises questions about how far droplets, like those that carry the virus that causes COVID-19, can travel before becoming harmless.

Carrying data streams using the terahertz (THz) spectral region could meet the ever-growing demand for unprecedented data transfer rates, i.e. terabits-per-second (Tb/s), since it offers a higher available bandwidth. However, it is extremely challengin…

Vaccine-associated myocarditis shows a similar injury pattern on cardiac MRI compared to other causes of myocarditis, but abnormalities are less severe, according to a new study.

Researchers have succeeded in developing a simple hydrocarbon molecule with a logic gate function, similar to that in transistors, in a single molecule. The discovery could make electric components on a molecular scale possible in the future.
