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.
Ultra-high powered lasers are the best and even cheapest approach to uncovering the secrets of physics, but with uses closer to home too.
Using fluorescent dye, researchers figured out how to turn cells into lasers – with applications for cell tagging and tracking as well as medical diagnoses and therapies.
The most powerful laser ever built could help us produce a machine that can turn energy into matter.
An exotic plasma could help shed light on why the universe as we know it is made up of more matter than antimatter.
During these dark winter months, spare a thought for artificial lights. From strings of lights adding holiday cheer to artificial sunlamps alleviating seasonal affective disorder, they brighten our days…
