| Posted: 14 Sep 2012 12:40 PM PDT NASA's long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers. Spherical objects concentrated at an outcrop Opportunity reached last week differ in several ways from iron-rich spherules nicknamed "blueberries" the rover found at its landing site in early 2004 and at many other locations to date.  |
| 'Memristors' based on transparent electronics offer technology of the future Posted: 14 Sep 2012 11:00 AM PDT Transparent electronics may find one of their newest applications as a next-generation replacement for some uses of non-volatile flash memory, a multi-billion dollar technology nearing its limit of small size and information storage capacity. The solution: memristors.  |
| First planets found around sun-like stars in a cluster Posted: 14 Sep 2012 10:34 AM PDT Astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster of stars. The findings offer the best evidence yet that planets can sprout up in dense stellar environments. Although the newfound planets are not habitable, their skies would be starrier than what we see from Earth.  |
| Posted: 14 Sep 2012 10:31 AM PDT Using ultrasound waves, engineers have found a way to enhance the permeability of skin to drugs, making transdermal drug delivery more efficient.  |
| A network to guide the future of computing Posted: 13 Sep 2012 05:46 AM PDT Moore's Law, the observation by Intel co-founder Gordon E. Moore that the number of transistors on a chip doubles approximately every two years, has been accurate for half a century. As a result, we now carry more processing power in the mobile phones in our pockets than could fit in a house-sized computer in the 1960s. But by around 2020 Moore's Law will start to reach its limits: the laws of physics will eventually pose a barrier to higher transistor density, but other factors such as heat, energy consumption and cost look set to slow the increase in performance even sooner.  |
| Seeing through clothing: Radiation-enabled chips could lead to low-cost security imaging systems Posted: 12 Sep 2012 01:15 PM PDT Scientists are reconfiguring existing semi-conductor computer chips and turning them into high-frequency circuits with the capability of seeing through packaging and clothing to produce an image of what is hidden underneath. The chip could be the basis of sophisticated but affordable, portable detection technology able to meet everyday security needs.  |
