To this end, advances in the science and technology of materials have provided the design and control of systems equipped with sensors and actuators built with new materials.... Success By Learning: Smallest Predator Recognizes Prey By Its Shape - The Etruscan shrew (Suncus etruscus) is one of the world's smallest mammals. It is about four centimetres long and weighs merely two grams. Being a nocturnal animal, it hunts predominantly with its sense of touch. "As quick as a flash, the Etruscan shrew scans its prey and adapts, when necessary, its hunting strategy," explained one of the researchers. "Thus, no prey escapes."... Gravity-defying Bird Beak Mystery Solved: Shorebirds Benefit From Surface Tension - As Charles Darwin showed nearly 150 years ago, bird beaks are exquisitely adapted to the birds' feeding strategy. A team of mathematicians and engineers has now explained exactly how some shorebirds use their long, thin beaks to defy gravity and transport food into their mouths. Some species rely exclusively on a feeding mechanism that takes advantage of water's surface tension, and so are extremely vulnerable to oil spills.... Common Virus May Serve As Target For Vaccine In Fight Against Deadly Brain Tumors - By targeting a common virus, doctors may be able to extend the lives of patients diagnosed with the most prevalent and deadly type of brain tumor. A type of herpes virus called human cytomegalovirus (CMV) is found in up to 80 percent of Americans, though the virus normally produces very few clinical symptoms, is dormant, and usually undetectable in most people.... New World Record For Efficiency For Solar Cells; Inexpensive To Manufacture - Scientists have improved the efficiency of an important type of solar cell from 21.9 to 23.2 percent (a relative improvement of 6 per cent). The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. The costs of applying the thin layer of aluminum oxide are expected to be relatively low.... Gastric Bypass Surgery Restores Sexual Function In Morbidly Obese Men - Losing weight may help resolve erectile dysfunction in obese men.

Current Regenerative Medical Techniques Hold Great Promise For Bladder Regeneration - Bladder regeneration via a neo-bladder replacement may prove to be effective in humans.... Pioneering Induction Of Bone Formation Using Embryonic Stem Cells - Researchers have successfully creating bone tissue "in vivo", using embryonic stem cells. They imitated bone formation in embryos and children, which uses cartilage as a template. This new approach appears to be a promising way of repairing bone defects. Previous attempts to create bone using embryonic stem cells were unsuccessful. In the lab, there was clear evidence that these stem cells were differentiating into the bone lineage "in vitro", however this process stalled after implantation and no bone tissue was formed. Yet, this approach did lead to bone formation when cultured adult stem cells from bone marrow were used. This direct approach is, amongst others, involved in the formation of the bone found in the skull.... Maternal Exposure To Persistent Organic Pollutants Linked To Urologic Conditions In Boys - Higher incidences of congenital anomalies, including cryptorchidism (undescended testicles) and hypospadias, were found in boys whose mothers had higher serum levels of certain organochlorine compounds, researchers say....

Nanotechnology In Reverse Uses Red Blood Cell To Calibrate Atomic Force Microscope - Nanotechnology researchers have shown that they can use a red blood cell to calibrate a sensitive instrument, an atomic force microscope. An atomic force microscope uses a tiny lever that runs over the surface of an object. Small deflections of the tip are read and translated to produce an image of the object's surface. However, accurate calibration of the springiness of the tip is difficult.... Having Less Power Impairs The Mind And Ability To Get Ahead, Study Shows - New research appearing in Psychological Science suggests that being put in a low-power role may impair a person's basic cognitive functioning and thus, their ability to get ahead.... Crystal (Eye) Ball: Visual System Equipped With 'Future Seeing Powers' - Catching a football. Maneuvering through a room full of people. Jumping out of the way when a golfer yells "fore." Most would agree these seemingly simple actions require us to perceive and quickly respond to a situation. An assistant professor of cognitive science argues they require something more -- our ability to foresee the future.... Most Effective Initial Therapy For HIV-1 Infection Identified - In the largest study of its kind to evaluate commonly used HIV drugs, researchers confirmed that one of the most frequently prescribed triple drug combinations for initial HIV infection is indeed the most effective at suppressing HIV. The study also found that a two-drug regimen performed comparably to the triple-drug regimens.... Deep Sea Methane Scavengers Captured - Scientists succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane into the atmosphere. These microorganisms that oxidize methane anaerobically are an important component of the global carbon cycle and a major sink for methane on Earth. Methane - a more than 20 times stronger greenhouse gas than carbon dioxide - constantly seeps out large methane hydrate reservoirs in the ocean floors, but 80 percent of it are immediately consumed by these microorganisms.... Prostate Cancer Increases The Risk Of Bone Fracture, Study Shows - As unlikely as it sounds, scientists have shown that there is a link between prostate cancer and a higher risk of bone fracture. Men with prostate cancer face a 50% higher risk of fracture, which increases to nearly doubled risk if they are receiving treatment.... Firearms Microstamping Feasible But Variable, Study Finds - New technology to link cartridge cases to guns by engraving microscopic codes on the firing pin is feasible, but did not work equally well for all guns and ammunition tested in a pilot study by researchers from the forensic science program at UC Davis.
