Phys.org / Ice may release more iron than climate models predict
Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in the Proceedings of the National Academy of Sciences demonstrates that ice actively speeds up the ...
Phys.org / Timing in early brain growth may explain why closely related mammals build strikingly different cortexes
The outer regions of the brain, the cortex, have specific layers of different cells—neurons—that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains. However, the proportions of different ...
Phys.org / Gentoo penguins cope with climate change heat waves by breeding earlier
Over the past few decades, heat waves have become more common in several parts of the world as our planet warms. That's a huge problem for many animals, as it can lead to habitat loss and push their bodies to lethal thresholds. ...
Tech Xplore / Unstable software tests ripple through 55% of OpenStack projects, costing 1,156 developer days
In a study published in IEEE Transactions on Software Engineering, researchers from Kyushu University have found that "flaky tests," which are unstable software tests that seem to randomly pass or fail, do not stay confined ...
Phys.org / Metal-free method unlocks selective carborane editing for cancer therapy and sensors
Carboranes are molecules composed of carbon, boron and hydrogen atoms that are proving to have applications of great interest in chemistry, materials science and biomedicine. They are being used, for example, in the fight ...
Phys.org / DNA reveals hidden UV defense network that dissipates energy in femtoseconds
New details of how DNA protects itself from harmful ultraviolet (UV) radiation show a hidden network of ultrafast molecular reactions that help prevent damage before it can trigger mutations that might lead to cancer, according ...
Medical Xpress / Whole organ 3D imaging reveals remaining insulin producing cells in type 1 diabetes
Researchers at Umeå University have conducted a unique three-dimensional mapping of an entire human pancreas. The study shows that insulin-producing cells can remain long after the onset of type 1 diabetes—a finding that ...
Phys.org / Collective vibrations unlock fast ion flow in superionic crystals
In the race to develop safer, faster-charging solid-state batteries and more efficient thermoelectric conversion technologies, engineers and scientists have long faced a fundamental challenge: how to ensure ions move through ...
Phys.org / Microcrystals in bioluminescent fish scatter light like a prism
Approximately 75% of marine organisms are bioluminescent, with specialized light-emitting organs called photophores. They use the light they produce for various purposes, like attracting mates, luring prey, or confusing predators.
Medical Xpress / Magnet-guided soft robots could lead to safer treatment of life-threatening blood clots
Researchers at Concordia have developed an AI-assisted technique and a robotic platform that may one day help surgeons perform safer, faster and less invasive procedures to treat conditions such as blood clots located deep ...
Tech Xplore / '5-in-1' seed-sized surgical robot switches tools in under one second
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a tiny seed-sized robot that can navigate across soft and uneven surfaces to perform five surgical functions wirelessly, paving the ...
Medical Xpress / CAR T moves beyond cancer, targeting autoimmune disease with immune system reset
At age 49, Jan Janisch-Hanzlik's multiple sclerosis was destroying her freedom to live the life she wanted. She gave up her active nursing job for a desk role. Frequent falls made her afraid to carry her grandchildren. She ...
