Scientists have found that non-native invasive insects and diseases are reducing the amount of carbon stored in trees across the United States.

Astronomers are using the intriguing TRAPPIST-1 planetary system as a kind of laboratory to model not the planets themselves, but how the coming James Webb Space Telescope might detect and study their atmospheres, on the path toward looking for life beyond Earth.

About 35 million years ago, an asteroid hit the ocean off the East Coast of North America. Its impact formed a 25-mile diameter crater that now lies buried beneath the Chesapeake Bay. A team of researchers has obtained drilling samples from the Ocean Drilling Project site 1073 and dated them with the ''uranium-thorium-helium technique'' for the first time.

New research details how two highly lethal viruses have greater pathogenic potential when their proteins are combined.

A new study in The Condor: Ornithological Applications finds that currently-available global positioning system (GPS) tracking devices, previously thought to not alter animal survival rates, can decrease greater sage-grouse survival.

Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study.

Microbial communities living in deep aquatic sediments have adapted to survive on degraded organic matter, according to a new study.

Scientists have demonstrated a potentially much brighter electron source based on plasma that could be used in more compact, more powerful particle accelerators.

Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new research.

A low-cost intervention aimed at fostering a growth mindset in students gave the students more confidence in their entrepreneurship abilities and helped them persist when challenges arose.

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study. The study was performed in mice, but the technique is likely to be widely applicable to other mammals as well.

Compared to people who only drank alcohol, those who used alcohol and marijuana simultaneously were more likely to drink heavier and more often, according to researchers. They were also more likely to experience alcohol-related problems -- like impulsive actions they later regretted.

The first study to systematically survey a single graduating class on the effect of a multi-year campaign against mental illness has found that college students exposed to certain anti-stigma messages and activities are significantly less likely to stigmatize people with these conditions.

Scientists have discovered how diatoms -- a type of alga that produce 20 percent of the Earth's oxygen -- harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.

Scientists have discovered a potential tool to enhance magnetization and magnetic anisotropy, making it possible to improve the performance of samarium-cobalt magnets.

Long-term exposure to air pollution was linked to increases in emphysema between 2000 and 2018, according to a new study.

A new study sheds new light on how the CD2AP gene may enhance Alzheimer's disease susceptibility.

For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment.

Researchers have discovered that removing a single enzyme in mice dramatically boosts survival from sepsis, an often fatal over-reaction of the immune system to infection. The finding provides a new and unexpected therapeutic target for new drug development.

Researchers analyzed thousands of climate change articles from 45 countries and territories around the world to determine how they frame the issue, and differences were revealed mostly by the wealth of the nation.

A new study shows that facial differences resulting from population divergence in first Americans is due to the complex interaction of environment and evolution on these populations and sheds light on how human diversification occurred after settlement of the New World.

Having one of the most powerful bites in the animal kingdom, crocodiles must be able to bite hard to eat their food such as turtles, wildebeest and other large prey. Now, researchers have found that crocodiles -- and even their plant-eating ancestors -- had thin tooth enamel, a trait that is in stark contrast to humans and other hard-biting species. These findings could suggest new approaches for...

Researchers compared CBD absorption in patients on an empty stomach versus a standardized fatty breakfast.

A new technique will help not only reduce greenhouse gas emissions, but the potential to reduce the overall dependence on petroleum.
