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.

Illustris computer simulation creates the first realistic virtual universe

By - May 7, 2014 3 Pictures
As you might expect, the scale and complexities of the underlying physics means creating a realistic virtual universe would require some hefty computing power. A team of astronomers is claiming to have achieved this impressive feat using a computer simulation called "Illustris," which took five years to program and, for the first time, can recreate the evolution of the Universe in high fidelity.
