| Germs add ripples to make 'groovy' graphene Posted: 11 Jul 2016 12:58 PM PDT Graphene, a two-dimensional wonder-material composed of a single layer of carbon atoms linked in a hexagonal chicken-wire pattern, has attracted intense interest for its phenomenal ability to conduct electricity. Now researchers have used rod-shaped bacteria -- precisely aligned in an electric field, then vacuum-shrunk under a graphene sheet -- to introduce nanoscale ripples in the material, causing it to conduct electrons differently in perpendicular directions. |
| Nanotech 'tattoo' can map emotions and monitor muscle activity Posted: 11 Jul 2016 12:58 PM PDT A new temporary 'electronic tattoo' that can measure the activity of muscle and nerve cells researchers is poised to revolutionize medicine, rehabilitation, and even business and marketing research. |
| If life can make it here, it can make it anywhere Posted: 11 Jul 2016 12:55 PM PDT If the origin of life is common on other worlds, the universe should be a cosmic zoo full of complex multicellular organisms. Scientists use the evolution of Earth life as a model to predict what humans might find living on distant planets and moons in a new paper. |
| Supercomputers fire lasers to shoot gamma ray beam Posted: 11 Jul 2016 12:13 PM PDT Supercomputer simulations have shown scientists a new way to generate controlled beam of gamma rays from lasers. Nearly one million CPU hours on Stampede and Lonestar HPC systems were needed for the particle-in-cell simulation. The Texas Petawatt Laser will use the simulations to guide experimental verification later in 2016. Gamma ray production would make possible basic science research and benefit society through brain imaging, cancer therapy, and anti-terrorist cargo scanning. |
| Monkeys in Brazil 'have used stone tools for hundreds of years at least' Posted: 11 Jul 2016 12:09 PM PDT New archaeological evidence suggests that Brazilian capuchins have been using stone tools to crack open cashew nuts for at least 700 years. Researchers say, to date, they have found the earliest archaeological examples of monkey tool use outside of Africa. |
| It depends on the level of stiffness: Researchers investigate beetle penises Posted: 07 Jul 2016 08:52 AM PDT The penis of the thistle tortoise beetle is as long as the beetle itself. Something that initially sounds exciting, can be complicated during mating. This is because the females also have a hyper-elongated sexual organ, which is additionally twisted in the shape of a spiral. How beetle reproduction can nevertheless be successful has now been investigated. |
