| Bringing dehydrated plants 'back to life': Possible key to desiccation-tolerant plants Posted: 05 Apr 2010 08:00 AM PDT Drought can take a toll on plants and animals alike. When cells are deprived of water, they shrink, collapsing in upon themselves and, without water as a medium, chemicals and enzymes inside the cells may malfunction. However, some plants, like the aptly named "resurrection fern," can survive extreme measures of water loss, even as much as 95 percent of their water content. How do the cells in these desiccation-tolerant plants remain viable?  |
| Discovery of new group of molecules could help fight spread of cancer and other diseases Posted: 05 Apr 2010 08:00 AM PDT A team of scientists has discovered a new group of molecules which could help fight the spread of cancer and other diseases. The new molecules are synthetic derivatives of a natural product known as UDP-Galactose, and block the activity of a group of enzymes called glycosyltransferases.  |
| Cassini Doubleheader: Flying By Titan and Dione Posted: 05 Apr 2010 08:00 AM PDT In a special double flyby early next week, NASA's Cassini spacecraft will visit Saturn's moons Titan and Dione within a period of about a day and a half, with no maneuvers in between. A fortuitous cosmic alignment allows Cassini to attempt this doubleheader, and the interest in swinging by Dione influenced the design of its extended mission.  |
| Baby's obesity risk: What's the mother's influence? Posted: 05 Apr 2010 08:00 AM PDT Ongoing studies could provide new insights into recommendations to aspiring moms that they achieve a healthy weight before they become pregnant, and to gain only the recommended amount of weight during their pregnancy.  |
| Medicine residues may threaten fish reproduction, Swedish study finds Posted: 05 Apr 2010 08:00 AM PDT Researchers in Sweden have discovered that traces of many medicines can be found in fish that have been swimming in treated waste water. One such medicine, the hormone levonorgestrel, was found in higher concentrations in the blood of fish than in women who take the contraceptive pill. Elevated levels of this hormone can lead to infertility in fish.  |
| For better romantic relationships, be true to yourself Posted: 05 Apr 2010 08:00 AM PDT Be true to yourself, and better romantic relationships will follow, research suggests. A new study examined how dating relationships were affected by the ability of people to see themselves clearly and objectively, act in ways consistent with their beliefs, and interact honestly and truthfully with others.  |
| Fermi maps an active galaxy's 'smokestack plumes' Posted: 05 Apr 2010 05:00 AM PDT If our eyes could see radio waves, the nearby galaxy Centaurus A (Cen A) would be one of the biggest and brightest objects in the sky, nearly 20 times the apparent size of a full moon. What we can't see when looking at the galaxy in visible light is that it lies nestled between a pair of giant radio-emitting gas plumes ejected by its supersized black hole. Each plume is nearly a million light-years long.  |
| Premature birth and brain damage: Inflammation may play a role Posted: 05 Apr 2010 05:00 AM PDT Researchers have gone some way to explaining what happens during premature births and how brain injury develops in premature babies. New findings show that inflammation in both the amniotic fluid and the baby's brain has a role to play, new research from Sweden reveals.  |
| Longer-lasting flowers: Fresh Ideas from new research Posted: 05 Apr 2010 05:00 AM PDT Tomorrow's fragrant bouquets and colorful potted plants might last longer, thanks to new research.  |
| Prostate cancer: How two key proteins interact at the molecular level Posted: 05 Apr 2010 05:00 AM PDT Scientists have determined how two proteins required for the initiation and development of prostate cancer interact at the molecular level, which could lead to improved treatments for the disease.  |
| Looking into the future of data-routing with IRIS Posted: 05 Apr 2010 05:00 AM PDT The Internet is on the verge of overheating, as big network routers are forced to sort through more and more data packets. One solution is to install photonic routers that leave data in the form of light, thereby avoiding unnecessary electronic processing. Researchers have built an operational photonic router prototype that could conceivably manage hundreds of terabits of data per second.  |
| Researchers design self-test for memory disorders Posted: 05 Apr 2010 05:00 AM PDT A self-administered test to screen for early dementia could help speed the diagnosis and subsequent treatment of memory disorders, including Alzheimer's disease. It could also provide health care providers and caregivers an earlier indication of life-changing events that could lie ahead. The handwritten self-assessment, which can take less than 15 minutes to complete, is a reliable tool for evaluating cognitive abilities.  |
| Posted: 05 Apr 2010 02:00 AM PDT There is strength in numbers if you want to get your voice heard. But how to do you get your say if you are in the minority? That's a dilemma faced not only by the citizens of a democracy but also by some neurons in the brain.  |
| New genetic risk factors for brain aneurysms identified Posted: 05 Apr 2010 02:00 AM PDT In the largest genome-wide study of brain aneurysms ever conducted, an international team of researchers has identified three new genetic variants that increase a person's risk for developing this deadly disease.  |
| Nanotechnologists reveal the frictional characteristics of atomically thin sheets Posted: 05 Apr 2010 02:00 AM PDT Nanotechnology researchers have used friction force microscopy to determine the nanoscale frictional characteristics of four atomically-thin materials, discovering a universal characteristic for these very different materials. Friction across these thin sheets increases as the number of atomic layers decreases, all the way down to one layer of atoms.  |
| Structure of key protein in common HIV subgroup uncovered Posted: 05 Apr 2010 02:00 AM PDT Scientists have provided the first-ever glimpse of the structure of a key protein -- gp120 -- found on the surface of a specific subgroup of the human immunodeficiency virus, HIV-1. In addition, they demonstrated that a particular antibody to gp120 makes contact not only with the protein, but with the CD4 receptor that gp120 uses to gain entrance into the body's T cells.  |
| Energy crops impact environmental quality, review finds Posted: 05 Apr 2010 02:00 AM PDT A new review of scientific literature finds that removal of crop residue for biofuels can adversely impact soil and environmental quality. Conversely, dedicated energy crops can increase soil organic carbon concentration while providing biofuel feedstock.  |
| Short-term program for binge eaters has long-term benefits, study finds Posted: 05 Apr 2010 02:00 AM PDT A new study finds that a self-guided, 12-week program helps binge eaters stop binging for up to a year and the program can also save money for those who participate. Recurrent binge eating is the most common eating disorder in the country, affecting more than three percent of the population, or nine million people, yet few treatment options are available.  |
| Turning noise into vision: New way to reveal images of hidden objects Posted: 04 Apr 2010 11:00 PM PDT Engineers have developed new technique for revealing images of hidden objects may one day allow pilots to peer through fog and doctors to see more precisely into the human body without surgery.  |
