Engineers have been developing solutions for the problematic interface between a Tram-Train vehicle and two very different railway infrastructures.
A pilot study has shown large variations between European countries in patient survival after surgery for oesophageal and gastric cancers. The reasons for these differences are not clear and cannot be explained simply in terms of the volume of patients treated at each hospital.
NASA's rover Curiosity, which landed on the surface of Mars on 6 August 2012, has led to more detailed estimates of the amount of water on the Martian surface.
New research suggests that fish accounts for only seven per cent of mercury levels in the human body. Concerns about the negative effects of mercury on fetal development have led to official advice warning against eating too much fish during pregnancy. A new finding suggests that those guidelines may need to be reviewed.
Critical gaps have been identified in breast cancer research. Scientists report on a gap analysis that critically assessed issues and new challenges emerging from recent breast cancer research, and propose strategies for translating solutions into practice.
Astronomers using data from NASA's Kepler and Spitzer space telescopes have created the first cloud map of a planet beyond our solar system, a sizzling, Jupiter-like world known as Kepler-7b. The planet is marked by high clouds in the west and clear skies in the east. Previous studies from Spitzer have resulted in temperature maps of planets orbiting other stars, but this is the first look at cloud structures on a distant world.
NASA's Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn's moon Titan. This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth.
Researchers have found that more than 90 percent of future retirees are contributing only a minimal amount of their salaries to their retirement funds.
Coping with a lot of stress in middle age may boost the risk of developing dementia in late life -- at least among women -- suggests research.
The international war on illegal drugs is failing to curb supply, despite the increasing amounts of resource being ploughed into law enforcement activities, finds research.
An analysis of a quality measure that Medicare Advantage plans self-report to the government finds that the insurers almost always err in their own favor. More elderly receive high-risk medications than the plans acknowledge.
A study has entered its second phase that focuses on developing innovative medical treatments for wounded veterans, including peripheral nerve regeneration, head and face trauma, burns, transplants and other conditions.
Scientists have made a discovery that, if replicated in humans, suggests a shortage of zinc may contribute to diseases like Alzheimer’s and Parkinson’s, which have been linked to defective proteins clumping together in the brain.
A new study has found that busy intensive care units (ICUs) discharge patients more quickly than they otherwise would, and do so without adversely affecting patient outcomes – suggesting that low-value extensions of ICU stays are minimized during times of increased ICU capacity strain.
Membrane proteins are responsible for transporting chemicals and messages between a cell and its environment. But determining their structure has proved challenging for scientists. A study demonstrates a new tool to resolve the structure of membrane-embedded and membrane-associating proteins using the water dynamics gradient they found across and above the lipid bilayer as a unique ruler.
Chemical engineering researchers have created a new synthetic metabolic pathway for breaking down glucose that could lead to a 50 percent increase in the production of biofuels.
A microfluidic chip developed at the University of Michigan is among the best at capturing elusive circulating tumor cells from blood -- and it can support the cells' growth for further analysis.
Women can choose among several types of estrogen pills, which are equally effective at relieving menopausal symptoms. But in a study, use of estradiol was associated with less risk of developing blood clots in leg veins (deep vein thrombosis) and clots in the lungs (pulmonary emboli) than was use of conjugated equine estrogens (Premarin).
People who exercised more than four hours per week in their leisure time had a 19 percent lower risk of high blood pressure than people who didn't exercise much. Physical activity at work was not linked to a lower risk of high blood pressure.
Mexican scientists identified and quantified the amount of aflatoxins (carcinogenic) in food such as corn tortilla, rice, chili pepper, processed sauces, chicken breast and eggs, and revealed its relationship with cervical and liver cancer in humans.
