The climate of Earth is shaped by the buried carbon carried by rivers.
Stories of land and life are carried by every river. It carries dissolved organic matter—bits of carbon from soil, plants, and human activity—into the sea. This material was followed by scientists from China's Nanjing Institute of Environment Sciences and the Institute of Science Tokyo through three rivers that met the Yellow Sea.

Is it possible for life to exist on Mars? Yeast provides a hint.
People have been making bread and beer with baker's yeast for generations. Few people thought that this microscopic organism could provide clues about how life can persist on an other planet, like Mars.

How bacteria move from land to sea is revealed by an unexpected discovery.
A new species of bacteria has been identified by Hawaiian scientists from saltwater off the island of Oahu. The discovery suggests a secret pathway that transports terrestrial microorganisms into the ocean.

'Super-Earth' is our best chance to date to find extraterrestrial life.
Just under 20 light-years away, astronomers have discovered a likely rocky "super-Earth" that might harbour life. The mass of the planet GJ 251 c seems to be nearly four times that of Earth. The fact that it orbits in the habitable zone—where, under ideal circumstances, liquid water may persist—has scientists excited.

The temperature of Earth is greatly influenced by tiny ocean shells.
Unbeknownst to us, marine life that forms microscopic calcium carbonate shells contributes to climate regulation. Researchers discovered that existing climate models under-represent the calcifying plankton, which includes coccolithophores, foraminifers, and pteropods, which are plankton-based shell builders.

The threats posed by today's melting glaciers are warned about by ancient sea levels.
According to a recent study, the global mean sea level changed significantly during the last Ice Age, not just at its conclusion, which is a significant reexamination of Earth's past. The 4.5 million-year-old work reframes scientists' understanding of ice sheets and climate pace.

Long-held beliefs about dinosaurs before an asteroid strike are called into question by new research.
According to recent studies, North American dinosaur populations were flourishing just prior to the asteroid collision that caused their global extinction 66 million years ago.

Researchers use light and crystals to create new materials on demand.
One day, it may be possible to "draw" rather than "grow" crystals for use in a wide range of applications, including lasers, LEDs, and the semiconductors used in sensors in astronomical instruments, which would result in improved performance and reduced prices.

A new telescope photograph shows the interstellar comet 3I/ATLAS blasting a jet towards the sun.
As our nearest star warms up a portion of the comet's surface, 3I/ATLAS is launching a jet of material in the direction of the sun. The composite image displays a white light, which is the comet's atmosphere or coma, and the nucleus, or frozen, rocky centre core, of 3I/ATLAS as a big, black dot. The purple-marked jet is blazing out in the direction of the sun, which is also how comets in the solar system often behave.

The IUCN has officially declared the once-widespread migratory bird known as the slim-billed curlew extinct.
There are now even more animals on the list of those driven to extinction. A charismatic bird, Australian marsupials, and a few plants are among the species that the International Union for Conservation of Nature (IUCN) has formally declared extinct in its most recent report.

The oldest known stalagmite, which dates back 289 million years, was discovered in rocks in Oklahoma.
Did you know that troglobites are organisms that only inhabit caves? Although it's not the most attractive name in the world, it seems appropriate. evokes visions of damp, chilly, and shadowy spaces where unidentified liquids, some of which have been found to be the oldest water on Earth—and people drank it!—drip from the roof.
