Researchers propose a new technique for making the Red Planet more habitable by engineering heat-trapping nanoparticles from Martian dust

At Mata Menge, researchers found a tiny adult upper arm bone that belonged to an individual who lived 700,000 years ago, shedding light on the origins of Homo floresiensis.

Fossils Shed New Light on Small 'Hobbit-Like' Humans That Lived on a Remote Island

Two teeth and a small adult arm bone found in Indonesia suggest the ancestors of Homo floresiensis were even shorter than scientists previously thought

Microwaves need to be cleaned regularly, just like other kitchen surfaces.

Your Microwave Is Teeming With Bacteria, Study Suggests

Researchers found thriving communities of microbes in microwave ovens used in home kitchens, shared spaces and laboratories

Scientists Enlist the Help of Sea Lions to Reveal a Unique View of the Ocean Floor

Australian researchers glued satellite-linked GPS cameras to the animals' backs to capture footage that could be vital to marine conservation efforts

Astronaut Buzz Aldrin, as photographed by Neil Armstrong on the surface of the moon during the Apollo 11 mission in 1969. Researchers looked at lunar soil samples collected during the Apollo missions for the new study.

Meteorite Strikes Are the Primary Creator of the Moon's Thin Atmosphere, Study Finds

Researchers examined lunar soil samples collected during the Apollo missions to determine which weathering processes contribute most to replenishing the moon's atmosphere

The Step Pyramid stands more than 200 feet tall and is made from stones weighing more than 650 pounds. Some other researchers are not yet convinced by the idea that it was built using a hydraulics system.

Ancient Egyptians May Have Used Hydraulic Lift to Build Pyramid

Researchers propose that a system of water could have lifted heavy stones to the height necessary to construct the Step Pyramid

A new study of giant danios (not pictured) suggests schools of fish save 79 percent more energy in turbulent conditions than fish swimming individually.

Swimming in Schools May Help Fish Save Energy in Turbulent Waters

A new study suggests schooling fish use up to 79 percent less energy in rough conditions than fish that swim alone

Vultures clean up carcasses quickly, preventing bacteria and pathogens from proliferating. 

When Vultures Nearly Disappeared in India, Half a Million People Died, Too, Study Finds

By being nature's clean-up crew, the often maligned birds help prevent the spread of diseases, according to a new study

Lava erupts from the Sundhnúkur volcano on June 3, 2024, on the Reykjanes Peninsula near Grindavik, Iceland. The volcano has erupted five times since December 2023, forcing evacuations of Grindavik and the Blue Lagoon geothermal spa.

Hidden Underground Magma Pools Fueled Iceland's Volcanic Eruptions, Study Suggests

A subterranean plumbing system of magma beneath the island’s Reykjanes Peninsula may have helped set off the recent series of eruptions that could last for centuries

Previous research has looked at the static electricity of bees, but the study authors write that the charges of butterflies hadn't been measured before.

Static Electricity May Help Butterflies and Moths Pick Up Pollen

A new study measured the insects' electrostatic charges and used computer simulations to show that the charges were strong enough to lift pollen

Why Are Giant, Ancient Tropical Trees Dying?

Scientists from an international project are racing to figure out what kills these anchors of their ecosystems—before it's too late to save them

A woman stands behind a model of a Neanderthal at the Natural History Museum in London. Contrary to the narrative that early humans left Africa roughly 50,000 years ago, a new study finds our species migrated from the continent on multiple occasions.

Early Humans Migrated Out of Africa Several Times, DNA Study Suggests

Homo sapiens interbred with Neanderthals as early as 250,000 years ago and may have ultimately bred them out of existence, according to new research

Scotty, the largest T. rex specimen on record, is on display at the Royal Saskatchewan Museum in Canada.

The Largest T. Rex Could Have Been 70 Percent Heavier Than Fossils Suggest

Two scientists used modeling to predict how big the giant carnivores could have really grown, making a point that fossils likely don't represent the largest or smallest individuals of a species

A team of archaeoastronomers suggests the Pyramid of the Moon in Teotihuacán, Mexico, may have been constructed to align with the movement of the sun.
