Instruments and Supplies RSS FeedsHalf-baked Asteroids Have Earth-like Crust - Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. But two newly discovered meteorites may rewrite the book on how some asteroids form and evolve....Feed Source: feeds.sciencedaily.com Low-carb Diets Prove Better At Controlling Type 2 Diabetes - In a six-month comparison of low-carb diets, one that encourages eating carbohydrates with the lowest-possible rating on the glycemic index leads to greater improvement in blood sugar control, according to Duke University Medical Center researchers.... Star Light, Star Bright, Its Explanation Is Out Of Sight - A mysterious flash of light from somewhere near or far in the universe is still keeping astronomers in the dark long after it was first detected by NASA's Hubble Space Telescope in 2006. It might represent an entirely new class of stellar phenomena that has previously gone undetected in the universe, say researchers.... 'On Switch' For Cell Death Signaling Mechanism Discovered - Scientists have determined the structure of the interactions between proteins that form the heart of the death inducing signaling complex, which is responsible for triggering apoptosis, or programmed cell death.... Tilting At Wind Farms - A way to make wind power smoother and more efficient that exploits the inertia of a wind turbine rotor could help solve the problem of wind speed variation, according to new research.... Test Will Catch Sports Cheats On New Endurance Drugs - Avoiding detection just got harder for drug cheats who try to use a particular range of untested, but potentially enhancing, compounds. In the past, tests have been developed once a drug is known to be in circulation. Now a German research team has developed tests for a class of drugs that they believe could be used in the near future.... Ancient Odor-detecting Mechanism In Insects Discovered - A newly discovered family of receptors in the fly nose fills in a missing piece of the insect olfactory system -- and also suggests a new role for a class of receptors long believed to be confined to the depths of the brain....

Mountaineers Measure Lowest Human Blood Oxygen Levels On Record - The lowest ever levels of oxygen in humans have been reported in climbers on an expedition led by UCL doctors. The world-first measurements of blood oxygen levels in climbers near the top of Mount Everest, published in the New England Journal of Medicine, could eventually help critical care doctors to re-evaluate treatment strategies in some long-term patients with similarly low levels of blood oxygen.... Restoring Trust Harder When It Is Broken Early In Relationship - In relationships built on trust, a bad first impression can be harder to overcome than a betrayal that occurs after ties are established, a new study suggests. While betraying trust is never good for a relationship, the results show that early violations can be particularly devastating, and plant seeds of doubt that may never go away.... Evolution In Action: Our Antibodies Take 'Evolutionary Leaps' To Fight Microbes - With cold and flu season in full swing, the fact that viruses and bacteria rapidly evolve is apparent with every sneeze, sniffle and cough.

For instance, previous studies have demonstrated that the structure, dynamics, and evolution of thunderstorms are very sensitive to cloud microphysical parameters.... 'It Takes Two To Know One': Shared Experiences Change Self-recognition - Looking at yourself in the mirror every morning, you never think to question whether the person you see is actually you. A new study challenges this common-sense notion about our own self image. The study shows for the first time that the image we hold of our own face can actually change through shared experiences with other people's faces.... Spookfish Uses Mirrors For Eyes - A remarkable new discovery shows the four-eyed spookfish to be the first vertebrate ever found to use mirrors, rather than lenses, to focus light in its eyes.... 'Scrawny' Gene Keeps Stem Cells Healthy - Stem cells are the body's primal cells, retaining the youthful ability to develop into more specialized types of cells over many cycles of cell division. How do they do it? Scientists have identified a gene, scrawny, that appears to be a key factor in keeping a variety of stem cells in their undifferentiated state. Understanding how stem cells maintain their potency has implications for basic biology and also for medical applications.... Cassiopeia A Comes Alive Across Time And Space - Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object.

Scientists now hope to learn how to control blood vessel development in humans in order to combat obesity and diabetes.... Asian Grasslands May Hold Global Promise To Restore Grasslands In Arid Areas - Grazinglands in the Asian steppes and the rangelands in the western United States share similar climates, vegetation, land-use practices and problems. So an Agricultural Research Service (ARS) scientist joined a search in Asia to find and preserve native forage plants--and to see if these plants can be used to sustain and restore arid grasslands in other parts of the world.... Producing A More Effective Oral Form Of A Powerful Disease-fighting Protein - Scientists in Japan are reporting an advance toward using a natural disease-fighting protein in pills or syrups that patients can take by mouth rather than injection. Their study is the first to show that coating the protein with a polymer material already in wide medical use can increase its absorption by the intestine....
