When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to friction and wear: Small crystalline regions, of which metals are typically composed, can be deformed, twisted or broken, or even fuse together. It is impo…

The world's oldest mammal has been identified using fossil dental records -- predating the previously confirmed earliest mammal by about 20 million years -- in a new discovery hailed as

The world's oldest mammal has been identified using fossil dental records -- predating the previously confirmed earliest mammal by about 20 million years -- in a new discovery hailed as "very significant" by researchers.

But carbon dioxide emissions resulting from the global reservoir-building spree in the 1960s and 1970s are falling.

During heavy rains, Hawaii's streams, rivers, and nearshore waters change on microscopic levels. Bacteria in these aquatic systems increase, and some of these bacteria can be harmful to human health. They can cause problems like gastroenteritis—also known as …

Imaging techniques down to the picometer scale are permitting detection of previously unknown alliances of cellular software with electrostatics and mechanics.

Webb's infrared eyes net a spider full of young stars.

Surely, the idea of surviving and thriving on the moon is a first-rate realization ... but not dying there.

Physicists and astronomers have studied gamma rays caused by the Sagittarius Dwarf, a small neighboring galaxy of our Milky Way. They showed that all the observed gamma radiation can be explained by millisecond pulsars, and can therefore not be interpreted as…

The Gunflint Formation, which straddles Lake Superior's northwestern shore, contains a treasure trove of geological clues about the evolution of life. After a recent geological reassessment of this area, a research team has unearthed new types of microfossils…

They were a fascinating and complex group of hominins.

Although the risk is small that threatening organisms will make their way to Earth via the Martian rock samples currently being collected, NASA is taking precautions. These samples—set to arrive in…

The changing seasons tell us much about the workings of nature. Now, a research group from Japan has discovered that the seasonal changes of tree leaf growth and shedding can have a big influence on climate even on small, local scales.

Researchers hope to create a new vaccine with it.

Every 200 million years, high-energy comets may pelt our planet as it passes through our galaxy's spiral arms.

The Japanese Plasmalogen Society (Office: Higashi-ku, Fukuoka, Japan; President: Yutaka Oomura) announced the research results that scallop-derived pl

NASA's Artemis 1 mission to the moon now faces a likely delay of six weeks after being scrubbed twice due to technical problems and having to find time on the launchpad that doesn't overlap with SpaceX.

Old-growth forests and managed forests with old-growth characteristics can provide relief from climate change for some bird species, research by the Oregon State University College of Forestry suggests.

Researchers discovered that Betelgeuse, a red giant star, appeared orange-yellow to observers on Earth nearly 2,000 years ago.

The Thwaites glacier around the US state of Florida has been given the moniker due to its huge size and the possibility of what could happen if it all melts — seas would rise more than two feet, leading to a climate change catastrophe. Now, new research shows…

NASA's veteran astronaut Stanley Love said that life in Elon Musk's Mars colony would be horrible while recalling his expedition to Antarctica.
