Phys.org / 'I can't work in the farce of climate change cruise tourism anymore': Why Antarctic guides quit their dream jobs
In the words of a former Antarctic tour guide we interviewed: "You'd see massive glacier calvings, and you'd just want to cry. But all the guests would be cheering. And you'd be like … 'can you not put two and two together?'"
Medical Xpress / Study identifies which bacteria trigger the 'farm effect' that makes children less prone to allergies
Children who grow up in a farm environment are less prone to allergies, asthma and hay fever than their classmates. This so-called farm effect has been identified in several observational studies worldwide. It is most likely ...
Phys.org / Pennsylvania roads are being coated in radioactive wastewater—here's why
Pennsylvania's roughly 100,000 oil and gas wells produce wastewater that's many times saltier than seawater and contains radium, a known carcinogen. For decades, that saltwater, called brine, was spread on dirt and gravel ...
Medical Xpress / Brain fluid structure may flag future dementia risk years before diagnosis
Dementia, a progressive loss of memory and decline in mental function that can be caused by various neurological conditions, is estimated to affect more than 57 million people worldwide. Identifying specific biological and ...
Phys.org / New Ribo-Tweezer tool can pluck individual protein pieces out of a working ribosome
Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and ...
Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
Phys.org / 'Bag of Bones' preserves rare three-tier prehistoric meal in Outback Queensland
An ancient marine 'crime scene' discovered near Richmond captures the world first evidence of a flying reptile being eaten by a sea monster… before that predator became dinner itself.
Medical Xpress / Overlooked plant proteins may boost gut health
Plant-based diets are good for you. They promote gut, immune, metabolic and cardiovascular health, in part by cultivating a diverse community of intestinal bacteria. These benefits have long been known to stem partly from ...
Phys.org / Scientists' biographies may demotivate, not inspire, children to study science
Currently popular biographies of famous scientists may demotivate—rather than inspire—children's desire to study or pursue careers in science, according to researchers who studied the messages in 422 bestselling children's ...
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Phys.org / Mesolithic hunter-gatherers on Malta relied on repeated sea crossings, study suggests
The existence of humans on Malta, a tiny Mediterranean island, during the Mesolithic period is puzzling. Archaeological evidence indicates that foragers occupied the Maltese islands between 8,500 and 7,500 years ago, and ...
Phys.org / Algal blooms accelerate plastic weathering, potentially fueling microplastic formation
Every summer, algal blooms turn rivers and lakes green. Although they are widely known as a major form of water pollution that makes water murky, a KAIST research team has now shown for the first time that algal bloom conditions ...
