Is this the sixth mass extinction on Earth? Fears could be exaggerated.
Earth is about to experience its sixth major extinction, according to headlines for years. Human activity, according to many experts, has accelerated the extinction of species to levels not seen since the extinction of the dinosaurs.

Humans evolved more quickly than any other ape, according to a new 3D skull research.
A lengthy evolutionary tale is concealed in every human face. Rapid change can be seen behind the flat cheekbones and curved cranium. According to a recent study from University College London (UCL), our skulls advanced quickly rather than merely evolving.

The Arctic once completely melted under a moderate environment is revealed in a hidden cave in Greenland.
The Arctic wasn't always dead and cold. Parts of northern Greenland were green, wet, and teeming with flowing water millions of years ago. Evidence of that lost warmth can now be found in a tunnel beneath its current ice.

Before they disappear, scientists are racing to name ocean creatures.
Our oceans are home to millions of species, many of which are still unidentified. Tragically, too, a great number of species are disappearing before we even realise they exist. Some vanish forever without being studied, photographed, or comprehended for their part in the complex web of life on Earth.

Dark matter may eventually be revealed via radio waves in the early universe.
The Universe was quiet long before the first stars formed. No galaxies. No illumination. Only huge expanses of hydrogen gas and dark matter, an enigmatic substance that shapes everything we see today.

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.
