Phys.org / Why a bizarre Brazil 'pterosaur' fossil is now being reclassified as a fish
Georges Cuvier, the 19th-century French anatomist who first recognized pterodactyls as flying reptiles, wrote that "of all the beings whose ancient existence has been revealed to us, [they are] the most extraordinary."
Phys.org / Madagascar's ancient baobabs store 700 years of climate secrets—what they reveal
Madagascar is home to seven species of baobab trees, of which six are found nowhere else on the planet. Many of the trees have been alive for well over 1,000 years. The ancient trees have become symbols of Madagascar itself. ...
Phys.org / How tiny cave shrimps power the underworld of the Yucatan
Beneath the lush rainforests of the Yucatan Peninsula lies a hidden, subterranean world: a vast network of flooded sinkholes and anchialine caves. These unique underwater systems, which mix fresh and saltwater and are influenced ...
Phys.org / Stem cell embryo model grows yolk sac without hypoblasts or gene editing
For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic manipulation. The models ...
Phys.org / A hidden property of light could power future nanomachines
Light does more than illuminate the world—it can also push and twist matter. It was back in the 1870s that James Clerk Maxwell first predicted that light carries momentum and can exert pressure on objects. Nearly a century ...
Phys.org / AI model accurately predicts the spread of wildfires in real time
USC researchers are developing a computational model that combines satellite data and physics-based simulations to forecast a wildfire's path, intensity, and growth rate. If you've ever been evacuated from your home during ...
Phys.org / How primitive plants evolved to survive Earth's most catastrophic extinction event
Earth responded to its most severe past warming event by evolving a new and bizarre type of photosynthesis that allowed a group of primitive plants to survive. Research led by the University of Leeds has revealed how lycophytes—a ...
Phys.org / Prototype thermal memory stores heat states with tiny voltages for days
Heat is a ubiquitous form of energy that, unlike others, is notoriously difficult to store due to its natural tendency to dissipate. While this property is essential for phenomena like solar energy reaching Earth, it also ...
Phys.org / A protein engineering method may lead to more exact cancer treatments
Enzymes called proteases act like molecular scissors for proteins in the body and play a role in therapies to stop viruses from replicating and to kill cancer cells. The development of these medicines, however, has been slowed ...
Phys.org / Connected habitats help frogs keep protective microbes and curb deadly fungus
Maintaining connections between natural habitats may support beneficial microbes that help wildlife defend against disease. In a new study of tropical amphibians, a team led by Penn State biologists found that amphibians ...
Phys.org / AI algorithm identifies cells across diverse biological images, cutting hours of manual labeling
Imaging is a critical technique in biology—from identifying cancerous cells in biopsies to observing how immune cells like macrophages hunt down and destroy pathogens. Traditionally, distinguishing and labeling individual ...
Phys.org / Plastic texturing kills viruses when they land
Researchers have developed a thin plastic film that tears apart viruses on contact, offering a promising new way to keep high-touch surfaces such as smartphones and hospital equipment from spreading disease. The innovation ...
