Phys.org / The dinosaurs that forgot how to fly
A new study led by a researcher from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv University examined dinosaur fossils preserved with their feathers and found that these dinosaurs had lost ...
Tech Xplore / Solar, onshore wind and gas backup are (still) the cheapest way to power Australia
What's the cheapest way to power Australia? Every year, CSIRO researchers and modelers seek to answer this very large question in their GenCost report.
Phys.org / Bird researchers use virtual reality to bring fieldwork experience to classroom
A flutter of blue and yellow darts through a field in late May. Trees, shrubs and summer flowers fill the landscape. A blue-winged warbler is just within reach, with one swift motion it can be gently grasped, banded and studied ...
Medical Xpress / Confused by the doctor's questionnaire? Study suggests it's common
Imagine sitting down for an appointment with a therapist—or any care provider. Perhaps it's the first time you've seen this provider, or the first time in a while. You'll likely need to fill out a form with a set of questions ...
Medical Xpress / Researchers challenge old mechanism behind skin discoloration from hydroquinone
Hydroquinone has long been used as the gold standard treatment for hyperpigmentation, yet despite its effectiveness, it has been associated with a severe adverse reaction known as exogenous ochronosis, where blue-black discoloration ...
Medical Xpress / Distinct components of mRNA vaccines cooperate to instruct efficient germinal center responses
mRNA vaccines, such as those used against COVID-19, are effective at generating antibody responses. These antibodies are produced through specialized immune structures called germinal centers, but until now it was not fully ...
Phys.org / Long-hypothesized dynamic transition seen in deeply supercooled water for the first time
In a new study published in Nature Physics, researchers have achieved the first experimental observation of a fragile-to-strong transition in deeply supercooled water, resolving a scientific puzzle that has persisted for ...
Tech Xplore / Transparency in AI companies falls to new low
A new analysis finds that AI companies now average just 40 out of 100 on transparency, marking a significant decline from last year.
Phys.org / Dazzling cosmic jet reveals time-stamped history of star birth
An international team of astronomers has uncovered the most unmistakable evidence yet that the powerful jets launched by newborn stars reliably record a star's most violent growth episodes, confirming a long-standing model ...
Tech Xplore / Researchers reveal bias in a widely used measure of algorithm performance
When scientists test algorithms that sort or classify data, they often turn to a trusted tool called Normalized Mutual Information (or NMI) to measure how well an algorithm's output matches reality. But according to new research, ...
Phys.org / Opposing forces in cells could hold clues to treating disease
A newly revealed molecular tug-of-war may have implications for better understanding how a multitude of diseases and disorders—including cancers, neurodegenerative diseases and immune disorders—originate, as well as how ...
Medical Xpress / Sharp rise in nicotine pouch use in Great Britain driven by young men
Use of nicotine pouches has risen substantially in Great Britain over the last five years, particularly among young men, with one in 13 (7.5%) men aged 16 to 24 now using them, according to a new study led by researchers ...
