Phys.org / Storms impact the architecture of webs and the survival of spiders
In the dense forests of the Ecuadorian Andes, the survival of a spider relies not only on its ability to prey on insects but also on its capacity to resist a threat coming from the skies. A new study revealed that the heavy ...
Phys.org / Engineers discover 'unexpected motion' in drug-delivery robots
One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. ...
Phys.org / Sea stars offer rare view of how embryonic tubes become complex organs
Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea stars may offer a unique window into the organ development process.
Phys.org / South Australian algal bloom species the world's most toxic harmful microalga yet recorded
The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.
Phys.org / Fighting the world's deadliest infection with PAC-MAN and AI
Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb), is the world's deadliest single-agent infection, responsible for 1.23 million deaths in 2024, according to the World Health Organization. The bacterium's ...
Phys.org / Bioinspired strategy creates complex 3D curved structures via programmed shrinkage
The shape of biological structures, ranging from flower petals to the limbs or organs of animals, is often naturally best suited for performing specific functions. Biological structures also often present curved surfaces ...
Phys.org / How an interstellar comet sheds light on universe's 'cosmic noon'
Last year, an interstellar traveler entered our solar system. Some speculated that it was an alien spacecraft, but it turned out to be a comet, 3I/Atlas, and it provoked interest from astronomers and astrophysicists eager ...
Medical Xpress / Scientists uncover two neuronal circuits orchestrating muscle autophagy
Autophagy is the process by which cells remove damaged proteins, recycle worn-out organelles (e.g., mitochondria), clear cellular waste and provide nutrients during stress. Autophagy is essential for muscles because they ...
Medical Xpress / Researchers uncover possible cause of muscle pain from widely used cholesterol medication
Millions of people rely on statins, a medication used to lower cholesterol and reduce the risk of heart attack and stroke. But for some, the drugs come with an unwelcome trade-off: muscle pain, weakness and exercise intolerance ...
Phys.org / Did elephant energetics decide Hannibal's Alpine crossing route?
A new analysis sheds light on the most likely route for the Carthaginian general's famous crossing of the Alps. The study, led by the University of Oxford and iDiv/Friedrich Schiller University Jena, reveals that the Col ...
Phys.org / Survival comes at a price: Frog study links salt adaptation to increased risk of disease
Over generations, a small North American frog has learned how to survive in a world that's getting increasingly saltier. But new research from the University of Missouri suggests that adaptation comes with an unexpected trade-off.
Phys.org / Electrical imbalances at grain boundaries help explain solid-state battery failure
Next-generation batteries that use new electrolyte materials could achieve far higher energy density than today's lithium-ion batteries, without many of the safety concerns. But advanced batteries, such as those that use ...
