New Haven, Conn.—Navigating our way down the street is something most of us take for granted; we seem to recognize cars, other people, trees and lampposts instantaneously and without much thought. In fact, visually interpreting our environment as quickly as we do is an astonishing feat requiring an enormous number of computations—which is just one reason that coming up with a computer-driven system that can mimic the human brain in visually recognizing objects has proven so difficult.

Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable effect.
Your friends are probably more popular than you are. And this "friendship paradox" may help predict the spread of infectious disease.
Air Force Office of Scientific Research-sponsored researcher, Dr. Robert Wood of Harvard University is leading the way in what could become the next phase of high-performance micro air vehicles for the Air Force.
OAK RIDGE, Tenn., Sept. 15, 2010 -- New insight into the structure of switchgrass and poplars is fueling discussions that could result in more efficient methods to turn biomass into biofuel.
Tackling today's complex scientific questions often requires work from interdisciplinary collaborative research teams – and working in those teams can create its own problems. Now a group of researchers from around the country, including North Carolina State University, has published a commentary in the journal Science Translational Medicine outlining a new field of study that will help resolve problems facing interdisciplinary research teams.
Rosemont, Ill. – Several health plans have introduced physician rating systems to offer consumers more information when choosing their doctors. However, a recent study presented in the September issue of the Journal of Bone and Joint Surgery (JBJS) reveals that physician-tiering guidelines and results are not consistent across insurance companies, do not fully define quality; and could confuse consumers.
Carbon nanotubes — those tiny particles poised to revolutionize electronics, medicine, and other areas — are much bigger in the strength department than anyone ever thought, scientists are reporting. New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other products.
SCOTTSDALE, Ariz. (Sept. 14, 2010) – A new investigational drug designed to penetrate and attack pancreatic cancer cells has been administered to a patient for the first time ever at the Virginia G. Piper Cancer Center at Scottsdale Healthcare.
ASG-5ME is a potent, targeted compound designed to selectively kill cancer cells, says Daniel Von Hoff, MD, a principal investigator in the Phase I clinical trial. Pancreatic cancer is a fast-growing and difficult to treat form of cancer, and is the fourth leading cause of cancer death in the United States.
BOSTON—Cancer patients who die in the hospital or an intensive care unit have worse quality of life at the end-of-life, compared to patients who die at home with hospice services, and their caregivers are at higher risk for developing psychiatric illnesses during bereavement, according to a study by researchers at Dana-Farber Cancer Institute.
Reducing the delivery of nutrients to the Chesapeake Bay is one of the most important components of restoration efforts to achieve a healthy Bay ecosystem. The USGS has developed a new method for tracking the progress toward reducing nitrogen and phosphorus delivery from the watershed to the Bay.
WEST LAFAYETTE, Ind. - Researchers at Purdue University have developed a facility aimed at learning precisely how coal and biomass are broken down in reactors called gasifiers as part of a project to strengthen the scientific foundations of the synthetic fuel economy.
Scientists at the University of East Anglia (UEA) are launching a groundbreaking new project to investigate the benefits of broccoli in the fight against osteoarthritis.
Initial laboratory research at UEA has found that a compound in broccoli called sulforaphane blocks the enzymes that cause joint destruction in osteoarthritis – the most common form of arthritis.
Broccoli has previously been associated with reduced cancer risk but this is the first major study into its effects on joint health.
If these walls had ears, they might tell a homeowner some interesting things. Like when water is dripping into an attic crawl space, or where an open window is letting hot air escape during winter.
