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 ...

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 ...

Glow-in-the-dark coughs and sneezes? In the coronavirus era, this is what it takes for scientists to figure out which masks work best at stopping aerosol droplets from spreading after a cough or a ...

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 ...

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that’s what happened in UMD’s Energy Research Facility, an unremarkable ...

Add Yahoo as a preferred source to see more of our stories on Google. In a discovery that could reshape how we view and understand the human brain, researchers have successfully passed a laser beam ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

Researchers set a record by guiding light in 45-meter-long air wave-guides. It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But ...
