| Researchers design, patent graphene biosensors Posted: 13 Nov 2015 08:24 AM PST Graphene is the first truly two-dimensional crystal, which was obtained experimentally and investigated regarding its unique chemical and physical properties. In 2010, two researchers were awarded the Nobel Prize in Physics "for ground-breaking experiments regarding the two-dimensional material graphene." There has now been a considerable increase in the number of research studies aimed at finding commercial applications for graphene and other two-dimensional materials. |
| Super environmentally friendly: the 'fool’s gold battery' Posted: 13 Nov 2015 08:01 AM PST High-performance lithium ion batteries face a major problem: Lithium will eventually start to run out as batteries are deployed in electric cars and stationary storage units. Researchers have now discovered an alternative: the "fool's gold battery". It consists of iron, sulfur, sodium and magnesium – all elements that are in plentiful supply. This means that giant storage batteries could be built on the cheap and used stationary in buildings or next to power plants, for instance. |

| Invasive freshwater species in Europe’s lakes and rivers: How do they come in? Posted: 13 Nov 2015 07:59 AM PST A new article has identified escape from aquaculture facilities, releases in the wild due to pet/aquarium trade and stocking activities as the main pathways of alien species introduction in European lakes and rivers. Germany, the UK and Italy are the main entry gateways. The authors recommend tightened controls, and improved prevention and management measures in order to halt the increasing trend of freshwater alien species introductions in Europe. |
| The dinosaur ankle re-evolved amphibian-like development in birds Posted: 13 Nov 2015 07:59 AM PST In the 19th century, Darwin's most vocal scientific advocate was Thomas Henry Huxley, who is also remembered as a pioneer of the hypotheses that birds are living dinosaurs. He noticed several similarities of the skeleton of living birds and extinct dinosaurs, among them, a pointed portion of the anklebone projecting upwards onto the shank bone (aka drumstick). This "ascending process" is well known to specialists as a unique trait of dinosaurs. However, until the late 20th century, many scientists were doubtful about the dinosaur-bird link. Some pointed out that the ascending process in most birds was a projection of the neighbouring heel bone, rather than the anklebone. If so, it would not be comparable, and would not support the dinosaur-bird link. |
