| New sunspots producing space weather Posted: 14 Jan 2013 02:21 PM PST On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later. |
| Tissue engineers report knee cartilage repair success with new biomaterial Posted: 14 Jan 2013 12:29 PM PST In a small study, researchers reported increased healthy tissue growth after surgical repair of damaged cartilage if they put a "hydrogel" scaffolding into the wound to support and nourish the healing process. The squishy hydrogel material was implanted in 15 patients during standard microfracture surgery, in which tiny holes are punched in a bone near the injured cartilage. The holes stimulate patients' own specialized stem cells to emerge from bone marrow and grow new cartilage atop the bone. |
| Noise protection: Multifunctional and aesthetical Posted: 14 Jan 2013 10:33 AM PST Noise abatement is growing in importance, thus, the demand for better acoustic building components raises. Scientists are developing new solutions: aesthetically good looking and flexibly applicable microperforated sound absorbers. |
| Building electronics from the ground up Posted: 14 Jan 2013 09:48 AM PST There's hardly a moment in modern life that doesn't involve electronic devices, whether they're guiding you to a destination by GPS or deciding which incoming messages merit a beep, ring or vibration. But our expectation that the next shopping season will inevitably offer an upgrade to more-powerful gadgets largely depends on size -- namely, the ability of the industry to shrink transistors so that more can fit on ever-tinier chip surfaces. |
| Multi-junction solar cell to break efficiency barrier? Posted: 14 Jan 2013 08:16 AM PST A novel, realistically achievable, lattice-matched multi-junction solar cell design has the potential to break the 50 percent power conversion efficiency. |
| New clean nuclear fusion reactor designed Posted: 14 Jan 2013 06:25 AM PST Researchers have patented a nuclear fusion reactor by inertial confinement that, apart from be used to generate electric power in plants, can be applied to propel ships. This invention helps solve the problem of contamination risk associated with the generation of nuclear fission power. |
| Star Wars: What would hyperspace travel really look like? Posted: 14 Jan 2013 06:25 AM PST The sight of the Millennium Falcon making the "jump to lightspeed" is one of the most iconic images from the Star Wars trilogy. |
