Phys.org / Heat waves on land start earlier and develop faster, global analysis reveals
Heat waves over land worldwide are beginning earlier, ending later and occurring over longer seasons, while the first heat wave of the season has recently shifted toward faster onset, according to a new study published in ...
Phys.org / Snapshots reveal key molecular machine in tropical parasites at near-atomic resolution
A study conducted by the University of Liège and Rockefeller University reveals, with near-atomic precision, the three-dimensional structure and function of a gigantic molecular machine essential to the survival of trypanosomatid ...
Phys.org / AI scans 4.6 million compounds in hours to predict hydrogen positions in drug-like molecules
New York University researchers have trained an AI model to learn chemical patterns associated with stability in drug-like molecules and accurately predict where their hydrogen atoms should be positioned.
Phys.org / Astronomers detect radio signals coming from an exoplanet for the first time
Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about ...
Phys.org / Light beam 'swims' upstream through a quantum fluid by violating Newton's third law
Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
Phys.org / Is a nearby advanced alien civilization out there waiting to pounce on Earth? Unlikely, says new study
Science fiction suggests that life on other planets, if it exists, is likely far more advanced than life on Earth. A recent study suggests otherwise.
Phys.org / What billiard balls reveal about computers and the limits of prediction
When is a billiard ball not a billiard ball? When mathematicians get involved and view a popular game as a model computer.
Phys.org / Injectable nanoparticles make blind retinas respond to light in preclinical study
An international research team has developed microscopic particles that can make blind retinas respond to light. The particles act as tiny light receptors. Researchers inject them into the eye, where they settle close to ...
Phys.org / Physicists crack the math connecting ultraslow quantum magnetism to ultrafast black-hole physics
A team led by University at Buffalo physicists has found a mathematical solution that shows how a frustrated quantum magnet can transition from ultraslow behavior to ultrafast, highly entangled behavior resembling that of ...
Phys.org / Queasy plesiosaurs swam to shore to vomit, Jurassic fossils reveal
Plesiosaurs swam into river deltas to vomit up shells and other indigestible elements of their marine meals, suggests new research published by Cambridge University Press. The behavior resembles that of today's fur seals ...
Phys.org / The secret to a perfect crystal may be a precisely calibrated extra turn
Creating a perfect crystal sounds straightforward: Arrange identical building blocks into a repeating, orderly structure. At the microscopic scale, though, even subtle biases in how particles interact can push them in preferred ...
Phys.org / From swarming bacteria to tissue cells, living matter defies classic physical models of motion
A new study led by researchers from Ben-Gurion University of the Negev (BGU) reveals that living matter violates previously known physical principles of symmetry when cellular flows form and break down collective patterns. ...
