Phys.org / New map reveals a rugged world beneath the Antarctic ice sheet
Scientists have discovered there is more to Antarctica than meets the eye. A new map of the landscape beneath the frozen continent's ice sheet has revealed a previously hidden world of mountains, deep canyons and rugged hills ...
Medical Xpress / What a study of 67,000 people reveals about sexual desire and age
Sexual desire is a fundamental part of being human and a driving force in many relationships, yet we still don't fully understand why it varies so much from person to person.
Phys.org / Construction emissions are higher than thought—but the solution isn't building less, new study finds
Many cities are making great strides in the fight against climate change, such as improving building energy efficiency, reducing traffic congestion and switching to renewable power sources. But there is another often overlooked ...
Phys.org / How concrete jungles could be changing dandelion seed dispersal in Japan
Dandelions are incredible plants with a highly efficient seed-dispersal system, meaning even a gentle breeze can carry seeds and their parachutes great distances. But in several places in Aichi Prefecture, Japan, they have ...
Phys.org / How prolonged maternal care in horses builds better brains and improves social skills
As with humans, the maternal bond in nature is important for animals to find their way in the world. In mammals, a mother does not just provide milk; she also teaches her offspring survival skills and how to play well with ...
Tech Xplore / Underwater robots inspired by nature are making progress, but hurdles remain
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 ...
Phys.org / Two simple modifications cool Kenyan homes and keep mosquitoes out
Researchers in Kenya have identified two low-cost solutions that tackle the twin challenges of rising temperatures and malaria transmission.
Phys.org / Sparse tongue hair explains why queen bees stop foraging when workers emerge
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 ...
Phys.org / Massive impact could be the cause of our lopsided moon
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 ...
Phys.org / Spaceflight causes astronauts' brains to shift, stretch and compress in microgravity
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. ...
Phys.org / Complex life on planets orbiting the galaxy's most common stars may be unlikely
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.
Phys.org / Sinking boreal trees in the deep Arctic Ocean could remove billions of tons of carbon each year
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 ...
Medical Xpress / How a miniature womb on a chip can help women struggling to conceive
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 ...
Phys.org / A new AI tool could dramatically speed up the discovery of life-saving medicines
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 ...
Phys.org / How personality traits influence the way we flirt with others
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. ...
