An increase in physical activity between the ages of 45 and 65 could help prevent Alzheimer's disease, while inactivity may be detrimental to brain health. An increase in physical activity between ...

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.

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 ...

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.

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 ...

Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that ...
