Phys.org / Congo River freshwater rides 49-day Atlantic eddy to travel 200 kilometers offshore
The Congo River is the second-largest river in the world, releasing an average of 40,000 cubic meters of water per second into the Atlantic Ocean. This huge discharge rate creates a large plume of fresh water that fans out ...
Phys.org / Study demonstrates neurotransmitter communication in immune cells directly for the first time
Researchers at the University of Münster and Ruhr University Bochum have demonstrated for the first time in real time that the body's own defense cells use catecholamines—neurotransmitters such as dopamine and adrenaline—to ...
Phys.org / Bottlenose dolphins in the Adriatic Sea seem to be heavily reliant on trawlers for food
Bottlenose dolphins in the Adriatic Sea are spending much of their time following trawlers to scavenge for food, scientists say. The Adriatic seabed has been plowed by bottom trawlers for decades, resulting in ecosystem damage. ...
Phys.org / Colony connections determine ant wound care: Transitional workers treat injured nestmates
Patients in hospitals generally trust the nursing staff. After all, they have undergone training and, in some cases, have several years of professional experience. In the case of carpenter ants, it is not nursing expertise ...
Phys.org / Paleontological study shows climate change makes marine animals shrink
Whether mussels, crustaceans or fish, marine animals have been responding to environmental crises with a reduction in body size for hundreds of millions of years. A new study by Friedrich-Alexander-Universität Erlangen-Nürnberg ...
Phys.org / Two centuries on, experts unlock secrets of Red Sea and Gulf of Aden sailing chart
Experts have unlocked secrets hidden for two hundred years in a beautiful navigational chart made for 18th century seafarers negotiating the Red Sea and Gulf of Aden. The paper scroll is evidence seafaring communities in ...
Phys.org / Visual map of 20,000 words reveals why lip-readers confuse common look-alikes
New research from the University of Kansas uses network science to determine why people make mistakes when lip-reading. Michael Vitevitch, professor of speech-language-hearing at KU, and his co-authors created a visual map ...
Phys.org / Quantum gravity tests may mistake ordinary spacetime for superposition
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic ...
Phys.org / What makes a star a star? A strange 'in‑between' celestial object is testing astronomers' boundaries
A star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself.
Phys.org / Spontaneous current loops in a kagome metal point to hidden quantum order
Quantum materials, materials exhibiting physical behavior governed by the laws of quantum mechanics, have proved promising for the development of numerous advanced technologies, including quantum technologies, memory devices ...
Phys.org / Analog gravity advance offers new insights into Hawking radiation from black holes
Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...
Phys.org / Quantum semiconductor design could expand search for dark matter
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that ...
