Scientists have learned how plants keep viruses from being passed to their offspring, a finding that could ensure healthier crops. The discovery could also help reduce the transmission of diseases ...

A new study offers the most detailed glimpse yet into how Earth's surface temperature has changed over the past 485 million years. The data show that Earth has been and can be warmer than today -- but ...

This discovery indicates that formaldehyde contributed to the formation of organic matter on ancient Mars, implying that bio-important molecules such as sugars and ribose (a component of RNA, which is ...

"Tidal heating plays an important role in the heating and orbital evolution of celestial bodies," said Alex Hayes, professor of astronomy. "It provides the warmth necessary to form and sustain ...

Ice may look safe for a game of pick-up hockey on the lake, but as a new study has found, looks can be deceiving. Warming winters are not only affecting ice thickness and timing -- when a lake freezes ...

Human breast milk regulates a baby's mix of microbes, or microbiome, during the infant's first year of life. This in turn lowers the child's risk of developing asthma, a new study shows.

Ancient DNA has provided spectacular insights into human history, particularly in Europe and Asia, where researchers have reconstructed the genomes of thousands of people. However, fewer than two ...

Millions of birds migrate every year to escape winter, but spending time in a warmer climate does not save them energy, according to new research. Using miniaturized loggers implanted in wild ...

Rising temperatures are thought to reduce the number of ice crystals in clouds, leading to the formation of liquid-dominated clouds. However, a new study has found that Arctic warming is causing an ...

Researchers have uncovered key insights into the dangerous phenomenon of 'river avulsion,' offering a way to predict when and where rivers may suddenly and dramatically change course. Indiana ...
