Phys.org / Deep inside crocodile skulls, 100 million years of brain evolution barely registers
Although modern crocodiles, alligators, caimans and gharials are restricted to the tropics, their fossil record tells a very different story. Ancient crocodylians once inhabited much of the globe and exhibited a remarkable ...
Phys.org / Ozone depletion began decades before discovery of ozone hole, scientists find
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
Medical Xpress / Neurobiologists improve symptoms of Huntington's disease with targeted brain stimulation in mice
Huntington's disease is a devastating brain disorder in which decaying nerve cells lead to progressively worsening cognitive and movement abilities. While the genetic mutation responsible for the condition is well known, ...
Phys.org / Space startup to launch India's first private orbital rocket
Indian startup Skyroot Aerospace said Thursday it would hold the maiden test flight of the country's first privately developed orbital-class rocket in the coming weeks.
Phys.org / Mice actively seek better views to make visual decisions, virtual reality experiments show
Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version ...
Phys.org / Loss of DNA protector gene exposes vulnerabilities in cancerous cells
Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this ...
Phys.org / How winter conditions shape future jellyfish blooms
Marine scientists at the University of Chester have discovered that environmental conditions experienced by jellyfish before winter can have lasting effects on the size and intensity of jellyfish blooms many months later. ...
Phys.org / Jellyfish reveal rapid repair system behind scar-free healing
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology ...
Medical Xpress / Shared neurodevelopmental spectrum could link ADHD, autism and dyslexia to later outcomes
A paper published in Molecular Psychiatry, led by researchers from Queen Mary University of London and Royal Holloway, University of London, challenges the way we think about neurodevelopmental conditions.
Phys.org / Black locust deploys peptides to steer root bacteria into nitrogen fixation
Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial ...
Tech Xplore / Germany's Infineon opens major chip plant as EU seeks tech autonomy
German semiconductor giant Infineon opened a five-billion-euro ($5.7 billion) microchip plant Thursday as Europe seeks to bolster its high-tech autonomy.
Phys.org / Beyond the 24-hour day: How employee biological clocks and beliefs drive workplace cooperation
Employees' biological clocks do more than determine when they reach for coffee; they fundamentally shape how, when and why people help each other at work. A study published in Organizational Behavior and Human Decision Processes ...
