Militaries around the world are scrambling to realise the ‘God mode’ of invulnerability and infinite ammunition promised by laser weapons.
Huge challenges remain before working fusion reactors are possible.
Toilets eject aerosol droplets that may carry disease-causing pathogens. Learning about how these particles move could help reduce exposure in public restrooms.
Build a powerful enough laser, and you can shine it into space. Aim it well, and you can blind satellites.
A US laboratory has announced an exciting new leap forward in nuclear fusion, but it may be several decades before we see this form of energy come to fruition.
Laser-cooling enables new measurements that could explain why antimatter is so scarce in our universe.
New research fired laser beams on tiger snake scales, and found arsenic was 20-34 times higher in wild wetland snakes than in captive snakes.
A new laser technique that measures the chemical make-up of whisky may help fight cancers.
For 60 years, physicists thought they knew exactly how coherent a laser could get. Now the ultimate quantum limit to laser coherence has been found, and it’s much much bigger than anybody thought.
A team of physicists, virologists and computer scientists are seeking to develop a coronavirus diagnostic tool that could deliver rapid results.
Following announcements by France and the US, NATO is expected to start using space weapons.
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.
