Your brain burns through the same amount of energy whether you're daydreaming or taking an exam. So why do we experience mental fatigue?

Brain-computer interfaces have the potential to transform some people's lives, but they raise a host of ethical issues, too.

Live Science spoke with biochemist Virginijus ikšnys, whose work helped establish CRISPR as a gene-editing system.

While atomic clocks are already the most precise timekeeping devices in the universe, physicists are working hard to improve their accuracy even further. One way is by leveraging spin-squeezed states in clock atoms.

A new kind of brain-scanning method may give a way to tell men's and women's brains apart, but a long history of incorrect claims in this field suggests the findings need to be further tested

Strange new types of cells keep coming to light in the human brain. By the latest count, there are more than 3300, and we don't even know what most of them do

The surprising discovery that your brain has its own microbiome is raising an intriguing possibility - that some dementias might be reversible

A collaborative project has made a breakthrough in enhancing the speed and resolution of widefield quantum sensing, leading to new opportunities in scientific research and practical applications.

A distant quasar that was initially mistaken for a star is actually one of the brightest and fastest-growing black holes ever seen.

People with higher levels of niacin in their blood may be more at risk of a heart attack or stroke, possibly because too much of the vitamin inflames blood vessels

The newly uncovered gene variants were identified as part of an analysis of the DNA of more than 400,000 people in the U.S. who agreed to participate in the All of Us Research Program.

Research is cutting through historical discrimination and gender politics to get to the truth about differences between the brains of men and women

A new study shows that invasive Joro spiders are surprisingly "urban tolerant," which could enable them to take over cities and other urban areas across the U.S. East Coast.

Quantum computing engineers at UNSW Sydney have shown they can encode quantum information--the special data in a quantum computer--in four unique ways within a single atom, inside a silicon chip.

Permafrost thaw could result in new rivers forming across the Arctic, potentially unleashing 35 million car journeys' worth of carbon every year.

Theoretical physicist Farokh Mivehvar has investigated the interaction of two collections of atoms emitting light inside a quantum cavity--an optical device consisting of two high-quality, tiny mirrors facing each other ...

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have synthesized two new isotopes--osmium-160 and tungsten-156--which sheds new light on nuclear struc...

In a new video, 1X's EVE robots work together in silence in a test environment, performing actions such as sorting mail, handling objects and tidying up a child's toys.

Earth lacks some of the ingredients that would have been key to the origins of life - they may have been delivered to glacial ponds by tiny specks of cosmic dust

We finally understand why blueberries are blue -- and the secret lies not in the flesh or skin, but the waxy coating around it.

Around one-fifth of the stem cells grown in laboratories for as-yet-unapproved medical treatments have cancer-causing mutations
