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 / Complex odors prove easier to map than expected with machine learning
If you want to describe a particular color, you could look to the Pantone color wheel to find its exact hue, saturation and brightness, and how it compares with other colors. But nothing like that has existed for complex ...
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 / Breaking up of swan families in winter disrupts spring migration
Young Bewick's swans only survive their first spring migration if they stay with their parents long enough. If they lose their parents in winter, they leave later and are unable to keep up with the rest of the population. ...
Phys.org / We're building a New York‑sized city every month. That's worrying for our climate
We each need a roof over our heads, classrooms to learn in and offices or spaces to work in. To meet this unprecedented demand for new buildings, globally, we're constructing the equivalent of an entire New York City every ...
Phys.org / Shark DNA could hold answers to how we age
Age isn't just a number for one of the ocean's top apex predators. It's a mystery University of Georgia researchers are solving. A new UGA study has determined how to estimate the age of sharks by analyzing changes to individual ...
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 / 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 / Blood-camouflaged nanoparticles defeat drug-resistant breast tumors in mouse model
Triple-negative breast cancer (TNBC) is one of the most aggressive and treatment-resistant subtypes of breast cancer, accounting for 15% to 20% of all cases. Unlike other breast cancers, TNBC lacks targetable receptors, leaving ...
Phys.org / Quantum dots keep their glow under heat after dual modification
Quantum dots are semiconductor crystals only a few nanometers in size. Their ability to produce bright, precisely tunable colors has made them promising materials for light-emitting diodes, displays, solar cells and other ...
Phys.org / Dark energy and quantum gravity may be deeply intertwined
For close to a century, physicists have pursued a way to unite gravity with quantum mechanics. Known as quantum gravity, this goal has remained frustratingly out of reach so far. Similarly elusive is the force of dark energy, ...
Phys.org / Rising carbon dioxide is supercharging grass growth in African savannas, study finds
Rising atmospheric carbon dioxide is boosting grass growth in Africa's water-limited savannas, according to a new study led by the University of Sheffield.
