Comparison of the primary outcomes of registered clinical trials with their subsequent publication appears to show some discrepancies, according to a new study.

Going back to the drawing board is much easier now that researchers have developed a new type of design program called FEAsy. The program allows the designer to sketch a rough concept of the part and then analyze the part's characteristics while it is still only a drawing.
As much as half of California could be occupied by new bird communities by 2070, according to a new study.
The presence of tumor cells circulating in the blood is associated with shortened survival. Now, researchers in Japan have developed a simple imaging system to detect circulating tumor cells, which could help clinicians hoping to predict a patient's chances of survival and/or monitor a patient's response to...
Body mass index readings may not be the best gauge of obesity in older adults, according to new research from endocrinologists and geriatricians. Instead, they say, the ratio of waist size to hip size may be a better indicator when it comes to those over 70. Obesity is often associated with premature mortality because it leads to an increased risk of diabetes, heart attack, stroke and other major...
The green mussel is known for being a notoriously invasive fouling species, but scientists have just discovered that it also has a very powerful form of adhesion in its foot. The stickiness of the mussel's foot could possibly be copied to form new artificial adhesives.
A new study shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed.
Veterinarians have found a solution to the challenge of providing effective pain relief to some of their most difficult patients: big cats.
German scientists identified serious and previously misunderstood contaminants that bring the safety and efficacy of intravenous treatments into question. In a new report, they show how a common intravenous treatment used to boost blood pressure in patients also contains substances called "advanced glycation end products," which trigger inflammation. This study directly challenges today's...
Using thin films of silk as templates, researchers have incorporated inorganic nanoparticles that join with the silk to form strong and flexible composite structures that have unusual optical and mechanical properties.
Researchers have shown for the first time that one component of clouds emitting unusual infrared light know as the Unidentified Infrared Bands (UIRs) is a gaseous version of naphthalene, the chief component of mothballs back on Earth. The UIRs have been seen by astronomers for more than 30 years, but no one has ever identified what specific molecules cause these...
Engineers have devised innovative computer software that can sift through hundreds of genetic mutations and highlight the DNA changes that are most likely to promote cancer.
A study of 7,689 admissions from 178 adult intensive care units in England, Wales and Northern Ireland has revealed the factors associated with a higher mortality rate in hematological malignancy. Researchers found that certain factors have a significant impact on the risk of...
Lakes in Antarctica, concealed under miles of ice, require scientists to come up with creative ways to identify and analyze these hidden features. Now, researchers using space-based lasers on a NASA satellite have created the most comprehensive inventory of lakes that actively drain or fill under Antarctica's ice. They have revealed a continental plumbing system that is more dynamic than...
Researchers have developed an innovative way to culture liver cells for drug toxicity screening. In a new report, they describe how liver cells grown in a high-oxygen environment and in a culture medium free of animal-derived serum quickly begin to function as they do within the...
Scientists here have demonstrated that the link between diesel fume exposure and cancer lies in how diesel exhaust induces the growth of new blood vessels that supply solid tumors. The researchers found that in both healthy and diseased animals, more new blood vessels sprouted in mice exposed to diesel exhaust than did in mice exposed to clean, filtered air. This suggests that previous illness...
At the end of July 2009, a team of cardiac surgeons in Germany was the first in the world to implant the HeartAssist 5 ventricular assist device, the modern version of the DeBakey VAD. The device augments the pumping function of the left ventricle in an especially effective, gentle and quiet manner. It pumps blood from the weakened or failed left ventricle into the...
Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering -- deliberate interventions in the climate system to counteract man-made global warming -- more...
Australian scientists have developed a new gene therapy vector that uses the same machinery that viruses use to transport their cargo into our cells. As a result, therapeutic DNA can be transferred to a cell's nucleus more efficiently than in the past, raising hopes for more effective treatment of genetic disorders and some types of...
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics.
The American Academy of Otolaryngology -- Head and Neck Surgery Foundation will issue the first -- and only -- national clinical practice guideline to help health care practitioners identify and manage patients with hoarseness, also known as dysphonia. The guideline emphasizes evidence-based management of hoarseness by clinicians, and educates patients on the prevalence of this common vocal health...
Researchers have found new evidence showing that parents play a key role in whether or not their adolescent children who experiment with tobacco progress to become daily smokers before they graduate from high school.
Computer scientists are using social networking tools to explore if individuals can enhance their personal and social wellbeing over time if they quickly share how they feel about issues such as their busyness, enjoyment, health and stress via these networks.
Previous studies have indicated that East Asia is where the wolf was tamed and became the dog. It was not possible to be more precise than that. But now researchers in Sweden have managed to zero in on man's best friend.
Biochemists have illuminated a reaction pathway that blocks the action of proteasomes, vital intracellular waste-processing plants. They report insights that could potentially lead to development of custom-tailored anti-cancer drugs with improved efficacy and safety.
