Scientists are digging into one of evolution’s strangest puzzles — why only certain creatures developed minds that know they exist.

Scientists have discovered that a mysterious foot found in Ethiopia belonged to a previously unknown ancient relative similar to Lucy.

Antarctica’s glacier retreated at an unprecedented speed, shrinking 25 kilometers in just 15 months. Find out how.

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.

"These confirmations have been given to us in writing, so this is a very important step."

NASA’s Mars Reconnaissance Orbiter just poked major holes in the idea of a subglacial lake beneath the Red Planet’s south polar ice cap.

An essential amino acid that is mistakenly believed to cause drowsiness after eating turkey has been found in an asteroid for the first time, giving scientists clues to the origin of life on Earth.

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection of an exceptional gamma-ray flare f…

Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing the reliability with which all …

Is this the first evidence of blue in prehistoric art? Archaeologists just found something that will leave you stunned.

The aptly named Butterfly Nebula is 2,500 to 3,800 light-years away in the constellation Scorpius.

For nearly a century, scientists have been searching for dark matter — the fundamental, invisible substance believed to make up most of the cosmos. After...

The egg was found preserved in Antarctica’s harsh environment—an unlikely place to find such a delicate structure. But its survival opens new possibilities in one of the planet’s least explored fossil frontiers.

Researchers have found footprints of large, bone-crushing dogs in the 12 million-year-old Ashfall Fossil Beds in northeastern Nebraska, suggesting these large carnivores may have survived a cataclysmic Yellowstone eruption that covered parts of North America …

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A groundbreaking scientific project known as QROCODILE, led by the University of Zurich and the Hebrew University of Jerusalem, has reached…

Pack your hot water bottle.

Entombed in total darkness for over 325 million years, two bizarre predators from a forgotten ocean have just resurfaced—perfectly preserved—in the unlikeliest place on Earth.

When ice freezes and melts, it creates vortices that drag warmer waters from the depths to the surface, where they eat away at the continent's rapidly degrading ice shelves.

Neuroscientist Nikolay Kukushkin spoke to Live Science about how human consciousness evolved.

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must advance down the gene in perfect sync …

Although American Thanksgiving only comes once a year, the scientific rules that make our Universe possible are always worth appreciating.

The cherry harvest wrapped up months ago. But in northern Michigan, some growers are already anticipating the spring resurgence of a tiny raptor that could benefit next season's crop.
