Underwater robots face many challenges before they can truly master the deep, such as stability in choppy currents. A new paper published in the journal npj Robotics provides a comprehensive update of where the technology ...

Researchers in Kenya have identified two low-cost solutions that tackle the twin challenges of rising temperatures and malaria transmission.

During spring, when queen bumblebees first emerge from hibernation to start their nests, they work incredibly hard foraging for nectar to fuel their new colonies. But then, as soon as their first workers are born, they seem ...

Our nearest neighbor, the moon, is still something of a mystery to us. For decades, scientists have wondered why it appears so lopsided, with dark volcanic plains on the near side (the side we see) and rugged, cratered mountains ...

Spaceflight takes a physical toll on astronauts, causing muscles to atrophy, bones to thin and bodily fluids to shift. According to a new study published in the journal PNAS, we can now add another major change to that list. ...

In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy.

Global efforts to reduce pollution will not be enough to mitigate the worst effects of climate change, scientists say. We will also need to extract over 10 gigatons of carbon dioxide from the atmosphere every year for the ...

A team of scientists from China has successfully created a miniature womb on a chip that mimics the complex environment of the human uterus. The research offers a new way to study the exact moment an embryo attaches to a ...

Researchers in China have unveiled a new AI framework that could accelerate the discovery of new medicines. DrugCLIP can scan millions of potential drug compounds against thousands of protein targets in just a few hours—ten ...

Flirting is often seen as playful behavior that signals interest to a potential partner. But according to new research, there is much more to the teasing, light-hearted conversation and coquettish glances than meets the eye. ...

Ceratopsians were horned, beaked dinosaurs that once stomped their way all over North America and Asia during the Late Cretaceous period, about 80 million years ago. Their abundance in the fossil records of these continents, ...

Albumin is the most common protein in the blood, a vital molecule produced by the liver that helps maintain fluid balance and transports proteins and hormones. It also plays a key role in fighting off a lethal disease called ...

For more than 70 years, what were thought to be mammoth fossils were tucked away in the archives of the University of Alaska Museum of the North. During the museum's Adopt-a-Mammoth program, which allows the public to sponsor ...

In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% of all species on Earth were wiped out, including the dinosaurs. Among those thought to have perished ...
