Phys.org / Forgotten museum fossil helps rewrite part of animal evolution
New research published in BMC Biology helps to fill in questions about the so-called "Furongian gap" from about 497 million to 485 million years ago, when paleontologists previously thought there were far fewer fossils than ...
Phys.org / MIZ-ing in action: How much of Antarctic sea ice is affected by waves?
Using old satellite radar techniques, scientists have developed a new way of measuring the true extent of an understudied and crucial region of the Antarctic sea-ice system for the first time. The Marginal Ice Zone (MIZ) ...
Phys.org / Divers may think they protect reefs, but one unseen habit is taking a steady toll
Research at the University of Sydney has found that scuba-diving tourism—widely promoted as a sustainable way to experience coral reefs—is causing frequent and often hidden damage to fragile marine ecosystems.
Medical Xpress / Scientists validate a link between autoimmunity and long COVID
A Mount Sinai-led research team has demonstrated that autoimmunity, in which the body's immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of ...
Medical Xpress / How gut microbes help shape how many calories you absorb from food
Food labels make calories seem simple. They show the number of calories per serving, which is calculated based on how much fat, carbohydrates and protein the food contains. But inside the body, digestion is far more complicated. ...
Phys.org / Electrical 'knob' can switch light on, off and tune intensity at the nanoscale
Physicists from Emory University have led work to develop a microscopic, nonlinear light source that can be switched on, off or tuned to a particular intensity by an electrical "knob." The paper is published in the journal ...
Phys.org / Deep beneath Utah, rare mantle earthquakes reshape seismic hazard questions
Nearly 50 years ago, a puzzling earthquake beneath northern Utah jolted scientists' understanding of how Earth works. Now, research from the University of Utah confirms that the mysterious event was real, and part of a rare ...
Phys.org / Global food shock model reveals self-sufficiency alone may not prevent crises
Global food systems are fragile. Recent shocks such as the closure of the Strait of Hormuz and the Russian invasion of Ukraine have raised prices and exacerbated food insecurity. Governments are increasingly trying to shield ...
Phys.org / In the world's economic 'black holes,' data still leak out
From satellite imagery to clandestine price reports, a new study draws on North Korea to explore economic activity in opaque regimes and information-scarce regions. North Korea is the blackest of economic black holes. Even ...
Medical Xpress / Naloxone use during cardiac arrest linked to improved survival
A new study by emergency medicine researchers at UC Davis Health set out to assess the effects of naloxone administration by first responders treating patients with out-of-hospital cardiac arrest (OA-OHCA). The study, published ...
Phys.org / Italians and Dutch share the same gestural instinct for teaching, research reveals
Italians are famous for speaking with their hands. But a new international study suggests that when it comes to teaching children, adults everywhere instinctively become more expressive with their gestures—even in cultures ...
Medical Xpress / AI suggests simple food swaps to make meals healthier and cheaper
An artificial intelligence framework that suggests just one to three ingredient swaps can make meals meaningfully more nutritious and less expensive, according to a new study published in PLOS Digital Health by Trevor Chan ...
