Phys.org / Ancient DNA reveals 1,000 years of human-environment interactions at Crawford Lake
An international team of scientists has recreated a 1,000-year timeline documenting ecological changes and human impact on the area surrounding Crawford Lake, the famed location of the proposed Anthropocene.
Phys.org / More than numbers: First global dataset shows who is immigrating
As countries compete for skilled workers and grapple with aging populations and labor shortages, understanding who is moving across borders is increasingly important. A new study provides the first global data set of immigration ...
Phys.org / Local microbes persist in wine despite commercial yeast
A new study has demonstrated that regional microbial imprints can remain detectable under commercial winemaking conditions. The research, appearing in Applied and Environmental Microbiology, shows that inoculated fermentations ...
Phys.org / Biologists find a hidden weak spot in how bacteria build the tails they use to move
New research from Indiana University has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. The researchers found that building these tails can put stress on the protective ...
Phys.org / Taxing billionaires and redistributing wealth could save millions of lives amid global aid cuts
Wealth redistribution policies currently under discussion in international forums could avert between 6.6 million and 29.5 million deaths by 2030, according to a study published in The Lancet and led by ISGlobal in collaboration ...
Phys.org / Families' interest in their kids' education is falling around the globe as scores drop, test shows
Families' interest in their kids' education is falling in many high-income countries as school systems struggle with plunging test scores, according to newly released results from a standardized test taken by 15-year-olds ...
Phys.org / AI D-Day weather forecast falters under pressure
Today's best weather computers would still have struggled to accurately predict the weather for the D-Day landings, University of Reading research shows. The new research, published in the journal Weather ahead of the release ...
Phys.org / GPS collars reveal secrets of the power struggle between lions and hyenas in the wild
Hidden deep in the bush, ranging over huge territories at speeds humans can't match and through terrain not even the most rugged vehicle can handle, hyenas and lions are hard to study. Now, new research using GPS collars ...
Phys.org / A photon that challenges Einstein: According to current physics, it should never have reached Earth
How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been absorbed long before reaching Earth? This is the question at the heart of a new study by Giorgio ...
Phys.org / Plants' response to rising CO₂ could put the brakes on dryland expansion
Drylands are defined as regions where rainfall is low relative to the atmosphere's ability to draw water from soil and plants. Expanding boundaries of these regions are frequent concerns in climate change considerations. ...
Phys.org / Big supernova dataset challenges dark energy theory
The most comprehensive catalog of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe's accelerating expansion. Researchers at The University of Queensland's ...
Phys.org / A new game demonstrates quantum advantage with provable classical limits
For decades, physicists have worked to prove the strange predictions of quantum mechanics with real experiments. As quantum computers have grown more powerful, researchers have devised increasingly sophisticated ways to test ...
