Researchers turn to cats to help soften robot landings

By - November 17, 2014 1 Picture
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

What "Star Wars" laser bolts would actually look like

By - October 22, 2014 3 Pictures
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

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.

Lasers could significantly shrink size and cost of particle accelerators

By - May 29, 2014 2 Pictures
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

Prime candidate crossed off list in search for dark matter particle

By - May 14, 2014 1 Picture
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Dresden, Germany have analyzed data from the HADES particle detector and concluded that the so-called "dark photons" are not the constituents of dark matter. Dark photons, or U bosons, are hypothetical particles that had thus far been the main candidate for that role, and this new result could make the search for the dark matter particle even more challenging than before.
