By Stephen Strauss of Nature magazine The hope that swarms of gamers can help to solve difficult biological problems has been given another boost by a report in the journal PLoS One, showing that data gleaned from the online game Phylo are helping to untangle a major problem in comparative genomics. The game was created to address the 'multiple sequence alignment (MSA) problem', which refers to the difficulty of aligning roughly similar sequences of DNA in genes common to many species.

Rapid cooling of ordinary water or compression of ordinary ice: either of these can transform normal H2O into an exotic substance that resembles glass in its transparency, brittleness, hardness, and luster. Unlike everyday ice, which has a highly organized crystalline structure, this glass-like material's molecules are arranged in a random, disorganized way. Scientists have studied glassy water for decades, but the exact temperature at which water acquires glass-like properties has been the subject of heated debate for years, due to the difficulty of manipulating pure glassy water in laboratories.

(PhysOrg.com) -- Of the many exotic and counterintuitive aspects of particle and quantum physics, exciton and polariton quasiparticles are among the most interesting. An exciton forms when a photon is absorbed by a semiconductor as a Coulomb force-bound state of a (negatively-charged) electron and a (positively-charged) hole; this particle pair can be seen as an elementary excitation of condensed matter able to transport energy without the transfer of net electric charge, and moreover has size- and shape-dependent optoelectronic properties

PGT: Ryo Ishikawa surged to the top of the leaderboard amid concern about his Japanese homeland, then was clearly distracted and struggled badly in Friday's second round.
