It just got harder to question the existence of black holes
No notion in physics may be more mind bending than a black hole, an infinitesimal pit in spacetime whose gravity is so strong that nothing can escape. But could very dense, dark objects be masquerading as black holes? A new study suggests not. Simulations show how any material object dense enough to resemble a black hole would be unstable, either puffing up into something less dense or...
Wild weather driven by roiling Pacific, nature and warming
In a world getting used to extreme weather, 2023 is starting out more bonkers than ever and meteorologists are saying it's natural weather weirdness with a bit of help from human-caused climate change.
When American democracy is weakened, faith in the U.S. as an ally falters
A new study finds that foreign interference in an American election can reduce faith abroad in the United States as an effective and trustworthy ally, suggesting that Russia's meddling in the 2016 election had some international ramifications.
Study explores how meaningful but unused products hinder sustainability
Custom sneakers, vintage dishware, a limited-edition car—each is an example of a product owners may regard as special and irreplaceable, fostering strong feelings of attachment.
'Veggie' dinosaurs differed in how they ate their food
Although most early dinosaurs were vegetarian, there were surprising differences in the way that these animals tackled eating a plant-based diet, according to a new study by scientists from the Natural History Museum and the Universities of Bristol and Birmingham.
Eye-tracking marketing research boosts public transportation agency's ridership
One of Florida's largest passenger rail services is experiencing an increase in ridership—and leaders of a Florida Department of Transportation program that promotes alternatives to commuters who drive alone attribute some of this success to guidance from an interdisciplinary team of researchers at USF who combined eye-tracking technology and social marketing to improve the impact of marketing...
Climate change could cause 'disaster' in the world's oceans, say scientists
Climate-driven heating of seawater is causing a slowdown of deep circulation patterns in the Atlantic and Southern oceans, according to Earth system scientists at the University of California, Irvine, and if this process continues, the ocean's ability to remove carbon dioxide from the atmosphere will be severely limited, further exacerbating global warming.
Study shows hydroponic systems as a promising method for sustainable saffron production
Saffron (Crocus sativus) is a geophyte perennial plant from the family Iridaceae with underground soft corms. The stigmas of the saffron flower have been cultivated as a spice for at least 3,500 years. Conventional cultivation processes, such as planting, flower harvesting, and separation of the stigmas, are labor-intensive and time-consuming. The labor costs and low supply contribute to the high...
After hurricanes, Florida neighborhoods see steady housing demand, wealthier residents
A new peer-reviewed study, which analyzes Florida housing markets battered by hurricanes, finds that affected areas tend to gentrify slightly in the years following a storm: The average income of new buyers increases while long-term demand stays stable.
Warmer climate increases Atlantic tropical storms, say cyclone researchers
A warming climate will increase the number of tropical cyclones and their intensity in the North Atlantic, potentially creating more and stronger hurricanes, according to simulations using a high-resolution, global climate model.
California's endangered salmon population plummets amid new threat
They've been pushed to the brink of extinction by dams, drought, extreme heat and even the flare of wildfires, but now California's endangered winter-run Chinook salmon appear to be facing an entirely new threat—their own ravenous hunger for anchovies.
Researchers detect fluoride in water with new simple color change test
Environmental contaminants like fluoride, lead and pesticides exist all around and even within us. While researchers have simple ways to measure concentrations of such contaminants inside lab environments, levels are much more difficult to test in the field. That's because they require costly specialized equipment.
Climate change could cause 'disaster' in the world's oceans

Climate change will slow down deep overturning ocean circulation in the coming centuries. Using three dozen Earth system models, researchers have concluded that the Southern Meridional Overturning Circulation could completely shut down by 2300, causing disaster to the marine ecosystem on a large portion of the planet.
Scientists develop a cancer vaccine to simultaneously kill and prevent brain cancer

Investigators have developed a new cell therapy approach to eliminate established tumors and induce long-term immunity, training the immune system so that it can prevent cancer from recurring. Dual-action cell therapy engineered to eliminate established tumors and train the immune system to eradicate primary tumor and prevent cancer's recurrence.
Potential new targets identified in advanced non-alcoholic fatty liver disease

Using the latest technologies --i ncluding both single-nuclear sequencing of mice and human liver tissue and advanced 3D glass imaging of mice to characterize key scar-producing liver cells -- researchers have uncovered novel candidate drug targets for non-alcoholic fatty liver disease (NAFLD).
New type of entanglement lets scientists 'see' inside nuclei

- 23/1/4 21:42
Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC) to see the shape and details inside atomic nuclei. The method relies on particles of light that surround gold ions as they speed around the collider and a new type of quantum entanglement that's never been seen before.
Climate risk insurance can effectively mitigate economic losses

Global warming is expected to lead to an accumulation of particularly intense hurricanes in the United States. This may substantially increase the economic losses caused by these storms. Better insurance could effectively mitigate the climate change-induced increase in economic losses. This is shown in a new study examining the effectiveness of climate risk insurance in the US.

An international team of scientists painstakingly gathered data from more than 50 years of seagoing scientific drilling missions to conduct a first-of-its-kind study of organic carbon that falls to the bottom of the ocean and gets drawn deep inside the planet.
