Beyond the abyss: Deep sea creatures build their homes from materials that sink from near the ocean surface (February 14, 2010) -- Evidence from the Challenger Deep -- the deepest surveyed point in the world's oceans -- suggests that tiny single-celled creatures called foraminifera living at extreme depths of more than ten kilometers build their homes using material that sinks down from near the ocean surface. ... > full story
A potent suppressor of endometrial cancer is revealed (February 14, 2010) -- Treatment of endometrial cancer has not advanced significantly in 30 years and there are no screening tests to promote early detection. Researchers have developed a new approach to specifically target genetic changes to the endometrial cells in mice. Using this new technique, they show that loss of an emerging tumor suppressor causes abnormal growth and widespread malignancy of cells lining the uterus. ... > full story
Link between exploration well and Lusi mud volcano, strongest evidence to date shows (February 14, 2010) -- Nearly four years ago, a volcano of mud erupted in the middle of an Indonesian suburb, eventually inundating four villages, displacing 30,000 people and causing a gas line explosion that killed 13. The mud volcano continues to erupt today. A new report blames a drilling company that was drilling a gas exploration well, not a relatively mild and distant earthquake. ... > full story
Diabetes drug ups risk for bone fractures in older women, study suggests (February 14, 2010) -- A new study finds women with type 2 diabetes who take a commonly prescribed class of medications to treat insulin resistance may be at a higher risk for developing bone fractures. After taking a thiazolidinedione (TZD) for one year, women are 50 percent more likely to have a bone fracture than patients not taking TZDs, according to study results. And those at the greatest risk for fractures from TZD use are women older than 65. ... > full story
Breakthrough for mobile television (February 14, 2010) -- Long Term Evolution, a new mobile telecommunications standard, is poised to revolutionize mobile internet. High transmission rates will soon be possible on mobile devices. For this purpose, researchers in Germany developed the cross-layer design SVC over LTE -- a coding method that offers HD films in real-time in the appropriate format for cell phones or netbooks. ... > full story
Assistive technology helps dementia sufferers get through the day (February 14, 2010) -- Tens of millions of elderly people in the EU suffering from mild dementia may be able to look after themselves, and free up their carers, thanks to a new system. ... > full story
New fiber nanogenerators could lead to electric clothing (February 13, 2010) -- In research that gives literal meaning to the term "power suit," engineers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles. The technology could eventually lead to wearable "smart clothes" that can power hand-held electronics through ordinary body movements. ... > full story
Genetic secrets to jumping the species barrier (February 13, 2010) -- Scientists have pinpointed specific mutations that allow a common plant virus to infect new species. Understanding the genetics of the key interactions between viruses and hosts could provide insight to how some viruses manage to jump the species barrier and even give us a better idea of how animal diseases are generated. ... > full story
New picture of ancient ocean chemistry argues for chemically layered water (February 13, 2010) -- Biogeochemists have developed a dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet. Working on rock samples from the Doushantuo Formation, South China, the research team is the first to show that Earth's early ocean chemistry during a large portion of the Ediacaran Period was far more complex than previously imagined. ... > full story
Restrictions on female plasma may not be warranted (February 13, 2010) -- Three years after the US blood banking industry issued recommendations that discourage transfusing plasma from female donors because of a potential antibody reaction, researchers discovered that female plasma actually may have advantages. ... > full story
Nanoscale structures with superior mechanical properties developed (February 13, 2010) -- Researchers have developed a way to make some notoriously brittle materials ductile -- yet stronger than ever -- simply by reducing their size. The work could eventually lead to the development of innovative, superstrong, yet light and damage-tolerant materials. These new materials could be used as components in structural applications, such as in lightweight aerospace vehicles that last longer under extreme environmental conditions and in naval vessels that are resistant to corrosion and wear. ... > full story
The biggest loser: Maternal obesity puts a load on her offspring that lasts a lifetime (February 13, 2010) -- As if there are not enough reasons for obese people to lose weight, a new research report adds several more. In a study involving rats, researchers found that obesity in mothers causes cellular programming in utero that predisposes offspring to inflammation-related disorders (such as Alzheimer's, Parkinson's, type 2 diabetes, stroke, heart disease and more) from birth, regardless of whether or not the offspring are obese themselves. ... > full story
