Phys.org / First Antarctic-wide map of grounded icebergs reveals 'picket fence effect' holding sea ice in place
For the first time, important features of the Antarctic coastal zone have been mapped at high resolution around the continent by training an artificial intelligence tool to accurately recognize grounded icebergs in satellite ...
Phys.org / Global study reveals hidden nutritional value of shellfish and other aquatic invertebrates
The nutritional value of aquatic invertebrates such as oysters, mussels and crabs has been significantly overlooked, according to a new study led by researchers at King Abdullah University of Science and Technology (KAUST). ...
Phys.org / Gondwana really was a supercontinent—and it may have helped kickstart life on Earth
Some 550 million years ago, Earth looked very different than it does today. The Southern Hemisphere was dominated by an enormous single continent known as Gondwana.
Phys.org / New screening system flags food-packaging chemicals linked to serious health risks
Packaged food usually sits in plastic-lined bags designed to keep air, moisture and contaminants out. That same protection can also increase the chances of chemicals from the packaging seeping into the food. When a chemical ...
Medical Xpress / Beating to a different drum: The hidden rhythms shaping heart rate
University of Melbourne researchers working on a large study of smartwatch data have found that the heart rates of 70% of people follow weekly, quarterly or even yearly cycles.
Medical Xpress / Regular ketamine infusions offer new hope for treatment-resistant bipolar depression
People living with treatment-resistant bipolar disorder still have options to manage their condition. However, the choices are often limited, may take weeks to work or fail to provide full relief. That has led to a search ...
Phys.org / Astronomers unmask a supernova impostor
A distant star has captured astronomers' attention over the past decade, teasing them with indications that it will soon explode as a supernova. But new research shows that something else entirely is behind the star's outbursts. ...
Medical Xpress / Why so few older Americans get counseling—and how it could help
People are living longer, reshaping what it means to grow old. By the late 2060s, an estimated 2.5 billion people worldwide will be 60 or older—more than the number of people who are under 18. The population ages 80 and older ...
Phys.org / Compost microbe yields enzyme that tackles polyurethane foam and nylon
Researchers from Aarhus University and the Danish Technological Institute have taken a new approach in the search for enzymes capable of breaking down some of the most difficult types of plastic to recycle. They collected ...
Medical Xpress / Researchers identify barriers to faster stroke treatment
When someone experiences a stroke, every minute can mean the difference between recovery and permanent disability.
Phys.org / Masked tectonic structures suggest Mercury contracted 40% more than its visible scars alone indicate
The surface of Mercury is filled with craters, ridges and steep cliffs. Over billions of years, as the planet's interior cooled, the planet also shrank. Just as the skin of a drying fruit wrinkles when what is inside it shrinks, ...
Phys.org / Unaccounted climate feedback loops may amplify warming by 20–30% this century, but cutting emissions will reduce risks
New research shows that warming-induced emissions—greenhouse gas emissions from natural sources driven by rising temperatures—could amplify global warming by approximately 20%–30% and add an estimated 0.2°C–0.4°C of warming ...
