| Scientists produce shortest electron bunches ever by surfing plasma waves Posted: 09 Oct 2015 12:55 PM PDT The shortest electron bunches ever produced have emerged in new research. The bunches were produced by focusing a high-power laser pulse into a supersonic helium gas jet. These 'bullets' of charged particles have a length that is one 300th of the breadth of a hair and travel at a speed close to that of light. They are also 10 times shorter than those produced from conventional accelerators. |
| Researchers develop deep-learning method for computers to predict daily activities Posted: 09 Oct 2015 12:54 PM PDT Researchers have developed a new method that teaches computers to 'see' and understand what humans do in a typical day using 40,000 images taken from an ego-centric camera. |
| Threat posed by 'pollen thief' bees uncovered Posted: 09 Oct 2015 12:54 PM PDT A new study has uncovered the secrets of 'pollen thief' bees -- which take pollen from flowers but fail to act as effective pollinators -- and the threat they pose to certain plant species. |
| How small is the smallest? New record of the tiniest free-living insect provides precision Posted: 08 Oct 2015 11:24 AM PDT The long-lasting search and debate around the size and identity of the world's smallest free-living insect seems to have now ended with the precise measurement and second record of the featherwing beetle species. Described in 1999, representatives of this minute beetle have recently been retrieved once again from fungus in Colombia. The smallest individual measured the astounding 0.325 mm. |
