How well laser therapy works depends on your type of hair and skin, the type of laser and the skill of the person operating it.
Nature can produce fractals, computers can, too. Could light be a fractal? The answer is yes.
The winner of the 2018 Nobel Prize in physics says scientists shouldn't feel pressured to do research that has economic or commercial ramifications. Science for the sake of science is more important.
Using lasers to trap and move particles changed the way we're able to study microscopic life.
The Nobel Prize for physics was awarded to three scientists for the inventions of optical tweezers – in which two laser beams can hold a tiny object – and a method for creating powerful lasers.
An astronomer suggests an idea to piggyback on the ambitious Breakthrough Starshot project that aims to send nano spacecraft to Alpha Centauri at a major fraction of the speed of light.
Technology which located Mayan cities has been used to rediscover a southern African city from the 15th century.
New research may help us to look for messages from alien civilisations.
To understand what is happening in an optical fibre, physicists can mimic a rupture of the flow of grains of light – the photons – thanks to a laser device.
Star Wars fantasy or effective weapon system of the future?
The Micius satellite will encrypt data using fundamental laws of physics rather than crackable codes.
Space lasers developed in the 1970s are being put to a brand new use.
The speed comparison between today's technology and femtosecond spintronics is like comparing the fastest bullet train on Earth to the speed of light.
Explosive developments driving the tiniest engines in the world.
No longer a toy: the industrial-grade lasers available online are a disaster in the making.
It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.
Physicists have for decades tried and failed to make superconductors that work at room temperature. But we're finally getting closer.
It's not easy – but we are moving in the right direction.
Lasers are getting smaller, cheaper and better. It's time we were far more careful with them.
Laser technology has come a long way, but not when it comes to razors.
