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 / 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 / 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 / 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. ...
