Physicists demonstrate conditions for laser-driven fusion

(PhysOrg.com) -- Currently, commercial nuclear power plants generate electricity using nuclear fission, in which an atom’s nucleus is split into lighter nuclei. But scientists are also researching the reverse reaction, nuclear fusion, in which two light atomic nuclei fuse to form a single heavier nucleus. Compared with fission, fusion has the potential to produce less radioactive waste while...

Blogging the Big Bang

Flying penguins vs plastic balls at the ExCel Centre. Justin Evans, a researcher at UCL, tells the tale...I arrived work this week with a renewed excitement about the future of science.Last week I, and a number of colleagues from the UCL particle physics group, were at the Big Bang Fair, one of the UK's biggest science and engineering fairs, at the ExCel centre in London. Our aim? To tell...

Arachnophobes beware: Hubble snaps close-up of the Tarantula (w/ Video)

(PhysOrg.com) -- The wispy arms of the Tarantula Nebula were originally thought to resemble spindly spider legs, giving the nebula its unusual name. The part of the nebula visible in this image from Hubble's Advanced Camera for Surveys is criss-crossed with tendrils of dust and gas churned up by recent supernovae. These supernova remnants include NGC 2060, visible above and to the left of the...

Asia's nuclear drive on despite Japan crisis

Asian governments that are ramping up nuclear power will face huge pressure to curb their programmes in the wake of Japan's atomic crisis, but dozens of reactors will still be built in the near future.

Health experts sound warning over iodine rush

Japan's nuclear crisis has sparked panic buying of iodine pills, with online bids exceeding $500 for a single packet, but health experts hosed down the hysteria and warned the pills are of limited use.

New research demonstrates language learners' creativity

New research published in Language, the journal of the Linguistic Society of America (LSA) firmly establishes that language learning goes well beyond simple imitation, and in fact that language learners are quite creative and remarkably smart. Not only are learners able to generalize grammatical restrictions to new words in a category – in this case, made-up adjectives – but they also do...
