Phys.org / Ocean plankton reveal sugar-for-nutrients partnership that sustains life in barren seas
In the vast, nutrient-poor regions of the world's oceans, there is a constant struggle for survival. Yet tiny organisms known as Collodaria have thrived there for millions of years. These Collodaria host microscopically small ...
Phys.org / First 15 days of egg development may determine survival for California's most endangered salmon
Sacramento River winter-run Chinook salmon are California's most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat ...
Phys.org / Thunderquakes enable seismic imaging of Earth's shallow subsurface
Seismic waves produced by thunderstorms, called thunderquakes, can be used as a novel source for seismic imaging, according to a new study led by researchers at Penn State.
Phys.org / Shipwrecks from WWI and WWII are polluting the North Sea
In April 1917, the German submarine UC-30 sailed beneath the waves off the coast of Rømø. It had originally been on a mission in Ireland, but after suffering engine trouble, it turned around and was almost home in Germany.
Phys.org / Twenty years and 7,500 fossils reveal what blurs Earth's marine fossil record
In productive marine environments, a square meter (10.8 square feet) of seafloor can be perforated by hundreds to thousands of isolated and interconnected tunnels through which crawl and writhe a cornucopia of clams, shrimp, ...
Phys.org / Hydrogel platform uses vitamin B2 and blue light to simplify living tissue models
Researchers at Tampere University have developed a versatile hydrogel platform that makes it easier to create customized biomaterials for tissue engineering, disease modeling, drug discovery and regenerative medicine. Their ...
Phys.org / Patience predicts longer education paths and faster earnings growth, real-money experiment finds
Some teenagers are happy to wait for a bigger reward tomorrow rather than cash in today. Others would rather take the sure thing now—or gamble on a risky, high-payoff bet. According to a new study, these everyday differences ...
Phys.org / Climate change could triple the price of wheat
Bread, pasta and breakfast cereals may seem far removed from dry fields in North America, Europe or Asia. Yet when water shortages hit several of the world's most important wheat-growing regions simultaneously, the consequences ...
Phys.org / Scientists uncover environmental cues behind black bear hibernation
New research from Virginia Tech scientists in the College of Natural Resources and Environment provides fresh insight into how environmental conditions influence black bear hibernation, with implications for wildlife management ...
Phys.org / Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields
An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...
Phys.org / Lab-grown brain models gain a sense of place
The human brain is often described as one of the most complex structures in biology, and much of its power comes from how it's organized. Its outer layer, the cerebral cortex, is not one uniform sheet. As the brain develops, ...
Phys.org / 'Rainbow-on-a-chip' could help unlock 6G networks and precision timing for quantum technologies
Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into ...
