Today's humans carry the genes of an ancient, unknown ancestor, left there by hominin species intermingling perhaps a million years ago.

A "hell ant" some 99 million years ago used its scythe-like jaws to trap a baby roach for its next meal — but then the pair got stuck in sap and were preserved for scientists to discover centuries later.

A team of researchers from Sweden, the U.S., Poland and the U.K. has found evidence that suggests the wealth gap in human communities goes back at least 6,600 years. In their paper published in the journal Antiquity, the group describes their study of skeletons in an ancient Polish graveyard and what they found.

Need light but want privacy? A new type of wood that's transparent, tough, and beautiful could be the solution. This nature-inspired building material allows light to come through (at about 80%) to fill the room but the material itself is naturally hazy (93%), preventing others from seeing inside.

Thirty thousand years ago, a dead star on the other side of the Milky Way belched out a powerful mixture of radio and X-ray energy. On April 28, 2020, that belch swept over Earth, triggering alarms at observatories around the world. The signal was there and gone in half a second, but that's all scientists needed to confirm they had detected something remarkable: the first ever "fast radio burst" (FRB) to emanate from a known star within the Milky Way, according to a study published July 27 in The Astrophysical Journal Letters.

Rats and bats that host pandemic pathogens like Covid-19 increase in damaged ecosystems, analysis shows

The dramatic drop in greenhouse gases and air pollutants seen during the global lockdown will have little impact on our warming planet say scientists. Their new analysis suggests that by 2030, global temperatures will only be 0.01C lower than expected. But the authors stress that the nature of the recovery could significantly alter the longer term outlook.

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and the Agency for Science, Technology and Research (A*STAR) have shown that applying 'temporal pressure' to the skin of mice can create a new way to deliver drugs.

Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions—delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under construction in France to demonstrate the feasibility of fusion power.

Scientists developed a pre-stressing concrete that expands as it hardens, offering new possibilities in lightweight construction.

The sticky silk threads of spider webs may be hiding a toxic secret: potent neurotoxins that paralyze a spider’s prey.

Singapore researchers have developed "electronic skin" capable of recreating a sense of touch, an innovation they hope will allow people with prosthetic limbs to detect objects, as well as feel texture, or even temperature and pain.

A team of researchers from the University of North Carolina at Charlotte and Stanford University has tested the viability of using a type of fungus found growing in some of the destroyed nuclear reactors at the former Chernobyl nuclear power plant site to shield astronauts from radiation. They have written a paper describing their work and have uploaded it to the bioRxiv preprint site.

As the COVID-19 pandemic shut down cities around the world, and major transportation systems slowed to a crawl, pollution levels plummeted by around 50% in Delhi, India, according to a recent report from the Massachusetts Institute of Technology. The researchers found an 8% increase in solar panel energy production as a result of clearer, less polluted skies in the region.

A researcher fed beetles to frogs. The encounter did not end as expected.

Underwater “sexual parasitism” between male and female allows two bodies to become one. Now we know the reason why.

Atomic bombs hastened the end of World War II. But they launched another kind of war, a cold one, that threatened the entire planet with nuclear annihilation. So it’s understandable that on the 75th anniversary of the atomic bomb explosion that devastated Hiroshima (August 6, 1945), reflections tend to emphasize the geopolitical dramas during the decades that followed.

Implanting mice with human astrocytes makes them demonstrably more intelligent than their non-human-hybrid peers.

In a press conference at the University of Chicago, the U.S. Department of Energy (DOE) unveiled a report that lays out a blueprint strategy for the development of a national quantum internet, bringing the United States to the forefront of the global quantum race and ushering in a new era of communi

A collaboration between researchers from the University of Western Australia and the University of California Merced has provided a new way to measure tiny forces and use them to control objects.
