Lego is a popular Christmas gift, and young and old alike can derive hours of pleasure building with those little plastic blocks. But, like a lot of playthings, the novelty wears off soon enough and you find yourself drifting back to watch Christmas TV re-runs. But what if you could use that Lego to construct real scientific equipment; would that maintain your enthusiasm? Well hang on to your plastic blocks, because engineers have designed an experiment that uses Lego and a few other bits and pieces that allows any keen tinkerer to build a device that not only determines Planck's Constant but may also help quantify the international standard unit of mass.  Read More

Researchers a Berkeley have claimed a world record energy level with their tabletop-size p...

Taking careful aim with a quadrillion watt laser, researchers at the US Department of Energy’s Lawrence Berkeley National Lab claim to have managed to speed up subatomic particles to the highest energies ever recorded for a compact accelerator. By blasting plasma in their tabletop-size laser-plasma accelerator, the scientists assert that they have produced acceleration energy of around of 4.25 giga-electron volts. Acceleration of this magnitude over the short distances involved correlates to an energy rise 1,000 times greater than that of a traditional – and very much larger – particle accelerator.  Read More

The animal kingdom is fertile ground for roboticists looking to improve on their designs, with everything from insects, fish, seahorses, jellyfish, caterpillars, snakes and birds providing inspiration. Now researchers at Georgia Tech are turning to cats to help soften robot landings. Rather than strapping some felines to a robot's underside, the team is studying the way cats twist in the air when falling to let future robots land safely from a jump or fall.  Read More

It's no secret that Star Wars is full of scenes that defy the laws of physics. From space battles inspired by WW I and II dogfights to beams of light clashing in lightsaber duels. The laser bolts fired from Han Solo's trusty blaster and Luke's X-wing also play by their own rules, traveling much slower than the speed of light and being perfectly visible in the vacuum of space. Researchers in Poland have now created a film to show what a laser bolt would actually look like.  Read More

Scientists have been observing the wave-particle duality of light for centuries, but never has light been seen to behave like matter. Until now, that is. Researchers at Princeton University have devised a method for giving light the properties of liquids and solids, with huge potential ramifications in the study of quantum mechanics and other areas of physics.  Read More

If you've ever tried to retrieve an object that's floating away in a lake or the ocean, then you'll know how frustrating it can be, trying to draw that item towards you. According to research recently conducted at The Australian National University (ANU), however, it's possible to move such objects in whichever direction you wish – as long as you can generate the right type of waves.  Read More

Fresh evidence has come to light supporting the theory that the particle detected at CERN's Large Hadron Collider (LHC) in 2012 is indeed the elusive Higgs boson. The work is the result of an international collaboration led by researchers from MIT, and confirms that the potential Higgs boson does exhibit the decay characteristics that would be expected under the Standard Model.  Read More

Researchers working at TU Delft's Kavli Institute of Nanoscience in the Netherlands claim to have successfully transferred data via teleportation. By exploiting the quantum phenomenon known as particle entanglement, the team says it transferred information across a 3 m (10 ft) distance, without the information actually traveling through the intervening space.  Read More

By exploiting the difference between the speed of two different beams of colored light when traveling through a heated crystalline disk, University of Adelaide researchers claim to have produced the world's most sensitive thermometer – with an accuracy of 30 billionths of a degree.  Read More

Lasers could dramatically shrink the size and cost of particle accelerators such as the LH...

Particle accelerators like the Large Hadron Collider (LHC) are wonders of modern engineering and vending machines for Nobel prizes, but they’re also large – as indicated by the LHC's name – and costly. A new theoretical study by the Lawrence Berkeley National Laboratory's Berkeley Lab Laser Accelerator (BELLA) Center suggests how lasers could dramatically shrink the size and cost of particle accelerator. If the models hold true, it could remove a significant bottleneck from physics research and open up such machines to industrial and medical applications.  Read More
