New explanation for star formation: Computer simulations to provide physical explanation for Larson’s Laws Posted: 21 Oct 2013 01:27 PM PDT Astrophysics researchers for the first time provides an explanation for the origin of three observed correlations between various properties of molecular clouds in the Milky Way galaxy known as Larson's Laws.

Hitchhiking virus confirms saga of ancient human migration Posted: 21 Oct 2013 01:26 PM PDT A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.

Researchers demonstrate efficient method for converting fat cells to liver cells Posted: 21 Oct 2013 01:26 PM PDT In a feat of modern-day alchemy with huge potential for regenerative medicine, Sscientists have developed a fast, efficient way to turn cells extracted from routine liposuction into liver cells.

Anthropologist studies the evolutionary benefit of human personality traits Posted: 21 Oct 2013 12:32 PM PDT Bold and outgoing or shy and retiring -- while many people can shift from one to the other as circumstances warrant, in general they lean toward one disposition or the other. And that inclination changes little over the course of their lives.

Risk of Amazon rainforest dieback is higher than IPCC projects, study suggests Posted: 21 Oct 2013 12:32 PM PDT A new study suggests the southern portion of the Amazon rainforest is at a much higher risk of dieback due to stronger seasonal drying than projections made by the climate models used in the latest report by the Intergovernmental Panel on Climate Change.

No known hominin is common ancestor of Neanderthals and modern humans, study suggests Posted: 21 Oct 2013 12:32 PM PDT The search for a common ancestor linking modern humans with the Neanderthals who lived in Europe thousands of years ago has been a compelling subject for research. But a new study suggests the quest isn't nearly complete. The researchers, using quantitative methods focused on the shape of dental fossils, find that none of the usual suspects fits the expected profile of an ancestor of Neanderthals and modern humans.

Nano-cone textures generate extremely 'robust' water-repellent surfaces Posted: 21 Oct 2013 10:11 AM PDT Scientists create surfaces with differently shaped nanoscale textures that may yield improved materials for applications in transportation, energy, and diagnostics.

Controlling triggers of age-related inflammation could extend 'healthspan' Posted: 21 Oct 2013 08:57 AM PDT Inflammation is the common denominator of many chronic age-related diseases such as arthritis, gout, Alzheimer's, and diabetes. But according to a study, even in the absence of a disease, inflammation can lead to serious loss of function throughout the body, reducing healthspan -- that portion of our lives spent relatively free of serious illness and disability.

Hair regeneration method is first to induce new human hair growth Posted: 21 Oct 2013 07:42 AM PDT Researchers have devised a hair restoration method that can generate new human hair growth, rather than simply redistribute hair from one part of the scalp to another. The approach could significantly expand the use of hair transplantation to women with hair loss, who tend to have insufficient donor hair, as well as to men in early stages of baldness.

Rings, dark side of Saturn glow in new Cassini image Posted: 21 Oct 2013 07:38 AM PDT The gauzy rings of Saturn and the dark side of the planet glow in newly released infrared images obtained by NASA's Cassini spacecraft.

Physical cues help mature cells revert into embryonic-like stem cells Posted: 21 Oct 2013 06:52 AM PDT Bioengineers have shown that physical cues can help reprogram mature cells back into pluripotent stem cells. The study demonstrates for the first time that biomaterials can help regulate the memory of a cell's identity.

Scientist uncovers internal clock able to measure age of most human tissues; Women's breast tissue ages faster than rest of body Posted: 20 Oct 2013 05:30 PM PDT A new study is the first to identify a biological clock able to gauge the age of most human tissues. Some parts of the anatomy, like a woman's breasts, age faster than the rest of the body.
