Like people, birds have fewer friends as they age, but the reasons why are unclear. New research suggests they may just have no drive to.

Becoming less sociable protects older monkeys from getting ill, new research shows.

There is a yawning gap between national policies to enhance biodiversity and the individual and small group behavioral changes that are critical to making a real difference.

Thin, stretchy skin -- like that of a pig or human -- significantly lessens the underlying damage that occurs when it's punctured. Pig skin even outperforms synthetic materials that are designed to mimic skin, a new study finds. Its special qualities, in particular its ability to dissipate the energy of...

The warming climate in polar regions may significantly disrupt ocean circulation patterns, a new study indicates. Scientists discovered that in the distant past, growing inflows of freshwater from melting Arctic sea-ice into the Nordic Seas likely significantly affected ocean circulation, sending temperatures plummeting across northern Europe.

Drawing on evidence involving about 25 million population worldwide, an international research team demonstrates that long-term exposure to ambient PM2.5 significantly increases the risk of asthma, affecting both children and adults. The researchers find that approximately 30 percent of new asthma cases worldwide were linked to fine particulate matter (PM2.5)...

Researchers have created a graphene-enhanced, 3D-printable concrete that improves strength and reduces carbon emissions by 31%, advancing sustainable construction.

The Arctic is warming at three to four times the global average. However, new research suggests the slowing of a key ocean current could reduce projected Arctic warming by up to 2 degrees Celsius by the end of the century.
