Fwd: Methane
'A powerful new model to detect life on planets outside of our solar system more accurately than ever before has been developed by researchers. The new model focuses on methane, the simplest organic molecule, widely acknowledged to be a sign of potential life. The new model has been tested and verified by successfully reproducing in detail the way in which the methane in failed stars, called brown dwarfs, absorbs light.'

Fwd: Ultrasound
'Researchers have demonstrated a technique for detecting and controlling ultrahigh frequency sound waves at the nanometer scale. This represents an advance towards next generation ultrasonic imaging with potentially 1,000 times higher resolution than today's medical ultrasounds.'

Fwd: Wormhole
'Although we have a pretty good idea that our galaxy contains a supermassive black hole at its core, there could be another — albeit rather exotic — explanation for our observations of Sagittarius A*. It might be a wormhole.
This is according to two researchers who explore the possibility in a new paper submitted to the arXiv pre-print service. Although their work is purely theoretical, Zilong Li and Cosimo Bambi of Fudan University in Shanghai have identified a specific emission signature surrounding their hypothetical wormhole, a signature that may be detected by a sophisticated instrument that will soon be attached to one of the world's most powerful telescopes.
ANALYSIS: Wormhole Time Travel 'Possible' (If You're a Photon)
Sagittarius A* (or Sgr A*) is a region in the Milky Way's core that generates powerful radio waves and astronomers have long suspected that it is the location of a black hole approximately 4 million times the mass of our sun. It wasn't until astronomers were able to track stars orbiting close to the suspected black hole's event horizon, however, that the supermassive black hole was confirmed to be there.
But supermassive black holes are a conundrum.
Now we know what signature our supermassive black hole generates, astronomers have discovered that the majority of other galaxies also possess supermassive black holes in their cores. Even when looking into the furthest cosmological distances at the youngest known galaxies, they also appear to host these black hole behemoths.'

Fwd: Health
'In a strategy that combines two of the hottest ideas in cancer research, scientists at the National Institutes of Health said they successfully attacked a woman's disease by using her immune system to home in on genetic mutations unique to her tumors.
The findings, published Thursday by the journal Science, come from just one patient—a 45-year-old woman in Montana. But researchers said her case, in which she received billions of immune cells specially grown to target her tumors, amounts to evidence the technique may be a way to treat many common cancers now considered difficult to target with the immune system.
So-called immunotherapy has so far shown the most promise in relatively rare cancers such as melanoma and kidney cancers.
This new approach "represents the blueprint for making immunotherapy available to treat common cancers," said Steven A. Rosenberg, chief of the Surgery Branch at the National Cancer Institute's Center for Cancer Research and senior author of the study. "We've figured out a way to target what is absolutely unique on each cancer. That is the mutations that make the cancer a cancer."'
'Researchers have discovered a natural molecule that could be used to treat insulin resistance and type 2 diabetes. The molecule, a derivative of omega-3 fatty acids, mimics some of the effects of physical exercise on blood glucose regulation.'

Graphene
'Graphene is the strongest, thinnest material known to exist. A form of carbon, it can conduct electricity and heat better than anything else. And get ready for this: It is not only the hardest material in the world, but also one of the most pliable. Only a single atom thick, it has been called the wonder material. Graphene could change the electronics industry, ushering in flexible devices, supercharged quantum computers, electronic clothing and computers. While the material was discovered a decade ago, it started to gain attention in 2010 when two physicists at the University of Manchester were awarded the Nobel Prize for their experiments with it. More recently, researchers have zeroed in on how to commercially produce graphene.
The American Chemical Society said in 2012 that graphene was discovered to be 200 times stronger than steel and so thin that a single ounce of it could cover 28 football fields. Chinese scientists have created a graphene aerogel, an ultralight material derived from a gel, that is one-seventh the weight of air. A cubic inch of the material could balance on one blade of grass. "Graphene is one of the few materials in the world that is transparent, conductive and flexible — all at the same time," said Dr Aravind Vijayaraghavan, a lecturer in nanomaterials at the University of Manchester. "All of these properties together are extremely rare to find in one material."
So what do you do with graphene? Physicists and researchers say that we will soon be able to make electronics that are thinner, faster and cheaper than anything based on silicon, with the option of making them clear and flexible. Long-lasting batteries that can be submerged in water are another possibility In 2011, researchers at Northwestern University built a battery that incorporated graphene and silicon, which the university said could lead to a cellphone that "stayed charged for more than a week and recharged in just 15 minutes." In 2012, the American Chemical Society said that advancements in graphene were leading to touch-screen electronics that "could make cellphones as thin as a piece of paper and foldable enough to slip into a pocket."'

Fwd: Herbivores
'New research demonstrates how carnivores transitioned into herbivores for the first time on land. Previously unknown, the 300-million-year old fossilized juvenile skeleton of Eocasea martini is less than 20 cm long. Found in Kansas, it consists of a partial skull, most of the vertebral column, the pelvis and a hind limb. By comparing the skeletal anatomy of related animals, scientists discovered that Eocasea martini belonged to the caseid branch of the group Synapsid. This group, which includes early terrestrial herbivores and large top predators, ultimately evolved into modern living mammals. Eocasea lived nearly 80 million years before the age of dinosaurs.'

Fwd: Clone
'In a cloning first, scientists create stem cells from adults
Scientists have moved a step closer to the goal of creating stem cells perfectly matched to a patient's DNA in order to treat diseases, they announced on Thursday, creating patient-specific cell lines out of the skin cells of two adult men.
The advance, described online in the journal Cell Stem Cell, is the first time researchers have achieved "therapeutic cloning" of adults. Technically called somatic-cell nuclear transfer, therapeutic cloning means producing embryonic cells genetically identical to a donor, usually for the purpose of using those cells to treat disease.
But nuclear transfer is also the first step in reproductive cloning, or producing a genetic duplicate of someone - a technique that has sparked controversy since the 1997 announcement that it was used to create Dolly, the clone of a ewe. In 2005, the United Nations called on countries to ban it, and the United States prohibits the use of federal funds for either reproductive or therapeutic cloning.
The new study was funded by a foundation and the South Korean government.
If confirmed by other labs, it could prove significant because many illnesses that might one day be treated with stem cells, such as heart failure and vision loss, primarily affect adults. Patient-specific stem cells would have to be created from older cells, not infant or fetal ones. That now looks possible, though far from easy: Out of 39 tries, the scientists created stem cells only once for each donor.'

Big Bang Discovery Opens Doors to the "Multiverse"
To cosmologists, our universe looks disturbingly fine-tuned for life. Without its Goldilocks-perfect alignment of the physical constants—everything from the strength of the force attaching electrons to atoms to the relative weakness of gravity—planets and suns, biochemistry, and life itself would be impossible...
If ours was the only cosmos spawned by a Big Bang, these life-friendly properties would seem impossibly unlikely. But in a multiverse containing zillions of universes, a small number of life-friendly ones would arise by chance—and we could just happen to reside in one of them.
