We transformed living cells into tiny lasers

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.

When science gets ugly – the story of Philipp Lenard and Albert Einstein

Scientists are not always as scientific as many suppose. Recent well-publicized cases of scientific fraud prove that scientists can be as susceptible to the allures of wealth, power and fame as politicians…
Magnets have mysterious powers – now shown to influence heat and sound. Magnet image via

Magnetic fields can control heat and sound

Sound waves are made of particles called phonons. New research shows they're affected by magnetic fields, with researchers able to steer heat magnetically.
A 3D artist has dissected the LHC in this composite image, showing a cut-out section of a superconducting dipole magnet. The beam pipes are represented as clear tubes, with counter-rotating proton beams shown in red and blue. Daniel Dominguez/CERN

The LHC is back and it’s ready to probe the limits of matter

The Large Hadron Collider is ramping up to probe even deeper into the fundamental constituents of matter.

Quantum computer makes finding new physics more difficult

Physicists often work unusual hours. You will find them running experiments at 4am and 10pm. This is because, so long as the pertinent conditions inside a lab – such as temperature or light level – are…

Is glass a solid or a liquid?

Before Pilkingtons invented plate glass in the mid-19th century, flat panes could not be made. Old windows are uneven. Some once thought this was because glass is a liquid that flows down slowly over the…
The Patriots ran away with the AFC Championship. What did deflated footballs have to do with it? USA Today Sports / Reuters

Football physics and the science of Deflategate

News reports say that 11 of the 12 game balls used by the New England Patriots in their AFC championship game against the Indianapolis Colts were deflated, showing about 2 pounds per square inch (psi…
Matthew McConaughey embodies the heroic scientist in Interstellar. Paramount

Scientists as Hollywood heroes

Interstellar’s protagonists spend a significant portion of the movie’s 169-minute running time giving mini-lectures – sometimes with props and a little whiteboard – on theoretical physics. The characters…
