Despite sounding like something out of pulpy '50s sci-fi, 'space lasers' are real – and astrophysicists have now spotted the ...

Cats love laser lights. And most human families with cats also love watching their cats play with laser pointers. And let's ...

“Such a system is indeed extraordinary,” said Dr. Thato Manamela. We are witnessing radio equivalent of a laser half way through the universe. The “laser” under discussion is not a beam of lightsaber ...

As red-light laser therapy gains popularity in Asia for slowing myopia in children, reports of vision damage have emerged, ...

Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

A razor-thin spike of radio light, tuned to a wavelength of about 18 centimeters, just traveled more than 8 billion light-years and still arrived loud enough to stand out in MeerKAT’s data. That ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
