Phys.org / Scientists simulating ant swarms find a 'first mover' can set the colony in motion
In ant colonies, a single ant can be the catalyst for a wave of mob activity, launching brief bursts of coordinated movement involving hundreds or even thousands of swarming workers, according to new simulations from New ...
Phys.org / Satellite constellations could create spiraling space debris
To date, close to 30,000 satellites have been launched into Earth's orbit, leading to mounting concerns over the debris created when they collide. In a new analysis posted to the preprint server arXiv, Hugh Lewis of the University ...
Phys.org / A new category of heat waves is melting western US snowpack faster
Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science ...
Phys.org / River shipping emits nearly one-quarter of global shipping CO₂, analysis finds
River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make ...
Science X / Why eye contact may help babies learn: A hidden link between two brains
Have you ever noticed how babies get hooked the moment someone makes eye contact with them? That eye contact is not only cute; it may also send a powerful message to a baby. For years, scientists have been investigating whether ...
Phys.org / Engineered microbe speeds CO₂ capture and recovers critical metals
A genetically engineered bacterium can rapidly break down one of Earth's most abundant minerals, opening a promising new pathway for simultaneously removing carbon dioxide from the atmosphere and recovering critical elements ...
Dialog / Bound gravitational waves inspired by photonic systems
When one mentions "waves," we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. ...
Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Science X / Tropical cooling points to a world 5.4°C colder at the Ice Age peak
During the Last Glacial Maximum, tropical regions with lush vegetation would have looked completely different. The last Ice Age reached its peak about 20,000–21,000 years ago, and massive ice sheets covered parts of North ...
Medical Xpress / A new target in the gut for reducing Alzheimer's risk
A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that could ...
Medical Xpress / Brain cancer cells exploit normal nerve signaling to multiply and invade, new study finds
Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but instead support neurons by maintaining their structure and function. They are the most common form ...
Medical Xpress / Fourteen foodborne parasites still drive 171 million illnesses worldwide, analysis finds
Recent Cyclospora outbreaks have renewed public attention to foodborne parasites, but they also highlight a broader reality: These diseases continue to affect millions of people around the world and remain a significant global ...
