Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, near a supermassive black hole.

If proven effective in humans, the vaccine could complement standard therapies for HPV-driven cancer, as well as inform the design of therapeutic vaccines for other diseases.

New research using a space-time phenomenon predicted by Einstein presents evidence that the invisible backbone of the universe may be much "fuzzier" than we realized.

An analysis of peatland soil samples and satellite images has found that wildfires on Alaska's North Slope are more frequent and severe now than they were at any point over the past 3,000 years.

The sewn hide, cordage and needles show how Indigenous Americans used complex technology to survive the freezing temperatures at the end of the last ice age and as a means of social expression.

A new polymer gel can deliver insulin through intact skin in animal tests. It could someday offer a path toward needle-free diabetes treatment, some say.

Huge-scale ecological engineering around the edges of one of the world's largest and driest deserts has turned it into a carbon sink that absorbs more CO2 than it emits, research suggests.

Scientists have identified the oldest mule remains ever found in the western Mediterranean.

Forty years ago, Voyager 2 flew past Uranus and observed radiation levels that defied explanation. Now, scientists may finally know exactly what happened.

A large, 20-year trial showed that speedy cognitive exercises could reduce the risk of Alzheimer's disease and other types of dementia. The question is, could these tasks be adapted into video games?

A small study hints that you can "trigger" memories of specific puzzles while a person dreams and that the dreamer may be more likely to solve the puzzle the next day.

New CT scans reveal the last moments of the Inca children who were sacrificed and mummified about 500 years ago.

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Archaeologists and student excavators uncovered a Viking Age pit full of dismembered remains near Cambridge, England.

The newly discovered sungrazing comet C/2026 A1 (MAPS) will undergo an extremely close slingshot around our star in early April, and could become bright enough to be seen without a telescope during the day.

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog of all subatomic particles and unveil the elusive identity of dark matter.

Archaeological remains on the Kitsissut islands off the coast of Greenland reveal that whole communities regularly journeyed across the dangerous Arctic waters.

Emerging evidence suggests that "night owls" are more likely to have poor heart health and a higher risk of heart attack or stroke than "morning larks." Why is that?

A study in Iceland found that microbes are hoarding more nitrogen for themselves, altering nutrient cycling and leaving less for plants.

Physicists saw excitons, a type of quasiparticle, undergo a reversible phase transition from superfluid to supersolid for the first time, opening new doors for studying extreme states of matter.
