Researchers have correctly placed the strange 16-million-year-old Necrolestes in the mammal evolutionary tree, unexpectedly moving forward the endpoint for the fossil's evolutionary lineage by 45 million years and showing that this family of mammals survived the extinction event that marked the end of the Age of Dinosaurs.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151318.htmHappy youngsters more likely to grow into wealthy adults, study findshttp://www.sciencedaily.com/releases/2012/11/121119151316.htm The first in-depth investigation of whether youthful happiness leads to greater wealth in later life reveals that, even allowing for other influences, happy adolescents are likely to earn more money as adults.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151316.htm'Different kind of stem cell' possesses attributes favoring regenerative medicinehttp://www.sciencedaily.com/releases/2012/11/121119151314.htm New and powerful cells first created in the laboratory a year ago constitute a new stem-like state of adult epithelial cells with attributes that may make regenerative medicine truly possible. Researchers report that these new stem-like cells do not express the same genes as embryonic stem cells and induced pluripotent stem cells (iPSCs) do. That explains why they don't produce tumors when they grow in the laboratory, as the other stem cells do, and why they are stable, producing the kind of cells researchers want them to.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151314.htmEvidence of a 'mid-life crisis' in great apeshttp://www.sciencedaily.com/releases/2012/11/121119151311.htm Chimpanzees and orangutans can experience a mid-life crisis just like humans, a study suggests.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151311.htmBody may be able to 'coach' transplanted stem cells to differentiate appropriatelyhttp://www.sciencedaily.com/releases/2012/11/121119151308.htm Pluripotent stem cells are nature's double-edged sword. Because they can develop into a dizzying variety of cell types and tissues, they are a potentially invaluable therapeutic resource. However, that same developmental flexibility can lead to dangerous tumors called teratomas if the stem cells begin to differentiate out of control in the body.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151308.htmHow yeast protein breaks up amyloid fibrils and disordered protein clumpshttp://www.sciencedaily.com/releases/2012/11/121119151220.htm Hsp104, an enzyme from yeast, breaks up both amyloid fibrils and disordered clumps. For stable amyloid-type structures, Hsp104 needs all six of its subunits, which together make a hexamer, to pull the clumps apart. By contrast, for amorphous, non-amyloid clumps, Hsp104 required only one of its six subunits.Mon, 19 Nov 2012 15:12:12 ESThttp://www.sciencedaily.com/releases/2012/11/121119151220.htmHold the ice: Chemists reveal behavior of antifreeze moleculeshttp://www.sciencedaily.com/releases/2012/11/121119151216.htm Chemists have discovered a family of anti-freeze molecules that prevent ice formation when water temperatures drop below 32 degrees Fahrenheit.

It represents the first new imaged exoplanet system in almost four years, has a mass about 13 times that of Jupiter and an orbit somewhat larger than Neptune's. The star around which the planet orbits has a mass 2.5 times that of the Sun, making it the highest mass star to ever host a directly observed planet.Mon, 19 Nov 2012 14:06:06 ESThttp://www.sciencedaily.com/releases/2012/11/121119140621.htmHuman brain, Internet, and cosmology: Similar laws at work?http://www.sciencedaily.com/releases/2012/11/121119140545.htm The structure of the universe and the laws that govern its growth may be more similar than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people, according to a new article.Mon, 19 Nov 2012 14:05:05 ESThttp://www.sciencedaily.com/releases/2012/11/121119140545.htmGreenland's viking settlers gorged on sealshttp://www.sciencedaily.com/releases/2012/11/121119132311.htm Greenland's viking settlers, the Norse, disappeared suddenly and mysteriously from Greenland about 500 years ago. Natural disasters, climate change and the inability to adapt have all been proposed as theories to explain their disappearance. But now a Danish-Canadian research team has demonstrated the Norse society did not die out due to an inability to adapt to the Greenlandic diet: an isotopic analysis of their bones shows they ate plenty of seals.Mon, 19 Nov 2012 13:23:23 ESThttp://www.sciencedaily.com/releases/2012/11/121119132311.htmClues to cause of hydrogen embrittlement in metals: Findings could guide design of new embrittlement-resistant materialshttp://www.sciencedaily.com/releases/2012/11/121119132309.htm Hydrogen can easily dissolve and migrate within metals to make these otherwise ductile materials brittle and more prone to failures. Now, researchers have shown that the physics of hydrogen embrittlement may be rooted in how hydrogen modifies material behaviors at the nanoscale. Scientists have now presented a model that can accurately predict the occurrence of hydrogen embrittlement.Mon, 19 Nov 2012 13:23:23 ESThttp://www.sciencedaily.com/releases/2012/11/121119132309.htmNeed to filter water?

Unlike most other cloaking techniques that rely on transformation optics, this one is based on the influence of the ocean floor?s topography on the various ?layers? of ocean water. At the American Physical Society?s (APS) Division of Fluid Dynamics (DFD) meeting, being held November 18-20, 2012, in San Diego, Calif., Reza Alam, assistant professor of mechanical engineering at the University of California, Berkeley, will describe how the variation of density in ocean water can be used to cloak floating objects against incident surface waves.Mon, 19 Nov 2012 10:45:45 ESThttp://www.sciencedaily.com/releases/2012/11/121119104529.htmSound bullets in waterhttp://www.sciencedaily.com/releases/2012/11/121119104527.htm Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers developed a nonlinear acoustic lens that can focus high-amplitude pressure pulses into compact ?sound bullets.? In that initial work, the scientists demonstrated how sound bullets form in solids. Now, they have done themselves one better, creating a device that can form and control those bullets in water.Mon, 19 Nov 2012 10:45:45 ESThttp://www.sciencedaily.com/releases/2012/11/121119104527.htmOwls' ability to fly in acoustic stealth provides clues to mitigating conventional aircraft noisehttp://www.sciencedaily.com/releases/2012/11/121119104525.htm Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth.
