A new study links fossilized flying reptile tracks to animals that made them. Fossilized footprints reveal a 160-million-year-old invasion as pterosaurs came down from the trees and onto the ground.

While Alzheimer's disease is mostly considered a disorder of the brain, emerging evidence suggests that the condition also affects other organs of the body. Working with the laboratory fruit fly, ...

New research suggests that the negative effects of the ozone hole on the carbon uptake of the Southern Ocean are reversible, but only if greenhouse gas emissions rapidly decrease. The study finds that ...

New research from an international group looking at ancient sediment cores in the North Atlantic has for the first time shown a strong correlation between sediment changes and a marked period of ...

The combination of air pollution, dense urban development and limited green spaces increases the risk of asthma in both children and adults.

Dementia usually affects older people, so when it occurs in middle age, it can be hard to recognize. The most common form is frontotemporal dementia (FTD), which is often mistaken for depression, ...

Researchers have found that wild orangutans vocalize with a layered complexity previously thought to be unique to human communication, suggesting a much older evolutionary origin.

Globally, soils store more than twice as much carbon as the atmosphere. Therefore, carbon uptake and release by soils constitutes a strong regulator of atmospheric concentrations of the greenhouse gas ...

A new study reveals that heat-tolerant symbiotic algae may be essential to saving elkhorn coral (Acropora palmata) -- a foundational species in Caribbean reef ecosystems -- from the devastating ...

Newly discovered weapons of bacterial self-defense take different approaches to achieving the same goal: preventing a virus from spreading through the bacterial population.

The Amazon rainforest may be able to survive long-term drought caused by climate change, but adjusting to a drier, warmer world would exact a heavy toll, a study suggests.

Researchers have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud, are moving in opposing directions along two distinct axes. They found that stars closer ...
