| Beyond silicon: Transistors without semiconductors Posted: 21 Jun 2013 09:10 AM PDT Scientists have built a nanoscale transistor that works at room temperature. The device, only 20 nanometers wide, is made of gold quantum dots mounted on boron nitride nanotubes.  |
| Help for African rhino poaching survivors Posted: 21 Jun 2013 06:55 AM PDT In Africa hundreds of rhinos are shot or immobilised by poachers every year to supply ground up horn for the Asian medicine market. It is reputed to make men virile and treat anything from stomach ache to cancer - all just a myth.  |
| Are Dogs 'Kids?': Owner-dog relationships share striking similarities to parent-child relationships Posted: 21 Jun 2013 06:55 AM PDT People have an innate need to establish close relationships with other people. But this natural bonding behavior is not confined to humans: many animals also seem to need relationships with others of their kind. For domesticated animals the situation is even more complex and pets may enter deep relationships not only with conspecifics but also with their owners. Scientists have investigated the bond between dogs and their owners and have found striking similarities to the parent-child relationship in humans.  |
| A cheaper drive to 'cool' fuels Posted: 21 Jun 2013 06:53 AM PDT Chemists have developed an inexpensive catalyst that uses the electricity generated from solar energy to convert carbon dioxide into synthetic fuels.  |
| Why our prehistoric, parasitic 'jumping' genes don't send us into meltdown Posted: 20 Jun 2013 10:22 AM PDT A new study reveals for the first time how the movement and duplication of segments of DNA known as transposons, is regulated. This prevents a genomic meltdown, and instead enables transposons to live in harmony with their hosts — including humans.  |
