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…
The latest advance used to help design new buildings and conserve our historic ones is a range of 3D modelling technologies. Using 3D models at the design stage improves better information to reduce production…
Most of the time we take light for granted. It arrives with the sunrise everyday and we turn it on with a flick of a switch every night. It appears to be ephemeral and benign to us humans but there is…
A new laser imaging system has been developed by researchers at the University of Queensland to safely view skin structures…
Professor Rodney Sinclair explains how advances in laser tattoo removal technology have enabled the relatively safe and easy removal of tattoos. But it is a medical procedure, and as laser dermatologist…
Optical scientists have developed a new laser technology that could one day be used to guide lightning away from buildings…
One of great challenges of the 21st century has been to develop ways to manipulate matter on smaller and smaller dimensions. As the great physicist Richard Feynman noted in his famous 1959 lecture, “There’s…
You’re probably familiar with how tattooing works: coloured ink is deposited via needles into the dermal layer of skin. But you’re probably less familiar with the process for having it removed: laser therapy…
The exact pressure that permanently changes copper crystals has been pinpointed, according to a study released today. The findings, published in the journal Science, show that when copper is compressed…
A PhD student from the University of Western Australia has developed a new method to measure gases. Scientist can now measure…
