Circulating tumor cells may be a promising alternative, noninvasive source of tumor materials for biomarker assessment, according to data presented at the 4th AACR International Conference on Molecular Diagnostics in Cancer Therapeutic Development.
Biomarker panel identifies prostate cancer with 90 percent accuracy
Researchers in England say they have discovered a set of biomarkers that can distinguish prostate cancer from benign prostate disease and healthy tissue with 90 percent accuracy. This preliminary data, if validated in larger ongoing studies, could be developed into a serum protein test that reduces the number of unnecessary biopsies and identifies men who need treatment before symptoms begin.
Heartbreak puts the brakes on your heart
Social rejection isn't just emotionally upsetting; it also upsets your heart. A new study finds that being rejected by another person makes your heart rate drop for a moment. The study is published in Psychological Science, a journal of the Association for Psychological Science.

Scientists have identified a genetic defect linked to migraine which could provide a target for new treatments...
Cancer-fighting Viagra, the drug that keeps on giving
The all-purpose wonder-drug Viagra has added another string to its bow – now the drug could be used in cancer chemotherapy
'Hobbit' was an iodine-deficient human, not another species, new study suggests
A new paper is set to re-ignite debate over the origins of so-called Homo floresiensis -- the 'hobbit' that some scientists have claimed as a new species of human. Researchers have reconfirmed their original finding on the skull that Homo floresiensis in fact bears the hallmarks of humans -- Homo sapiens -- affected by hypothyroid cretinism.
Garlic oil shows protective effect against heart disease in diabetes
Garlic has "significant" potential for preventing cardiomyopathy, a form of heart disease that is a leading cause of death in people with diabetes, scientists have concluded in a new study. Their report, which also explains why people with diabetes are at high risk for diabetic cardiomyopathy, appears in ACS' bi-weekly Journal of Agricultural and Food Chemistry.
UT MD Anderson study finds women treated for breast cancer while pregnant have improved survival
Long associated with a worse outcome, researchers at the University of Texas MD Anderson Cancer Center have discovered that women treated for breast cancer while pregnant, in fact, have improved disease-free survival and a trend for improved overall survival compared to non-pregnant women treated for the disease.
Newly discovered planet may be first truly habitable exoplanet
A team of planet hunters has announced the discovery of an Earth-sized planet (three times the mass of Earth) orbiting a nearby star at a distance that places it squarely in the middle of the star's "habitable zone," where liquid water could exist on the planet's surface. If confirmed, this would be the most Earth-like exoplanet yet discovered and the first strong case for a potentially habitable one.
Study finds first direct evidence that ADHD is a genetic disorder
Research funded by the Wellcome Trust provides the first direct evidence that attention-deficit/hyperactivity disorder, or ADHD, is a genetic condition. Scientists at Cardiff University found that children with ADHD were more likely to have small segments of their DNA duplicated or missing than other children.
National study finds strong link between diabetes and air pollution
A national epidemiologic study finds a strong, consistent correlation between adult diabetes and particulate air pollution that persists after adjustment for other risk factors like obesity and ethnicity, report researchers from Children's Hospital Boston. The relationship was seen even at exposure levels below the current EPA safety limit.
Notre Dame and Wyoming scientists genetically engineer silkworms to produce artificial spider silk
A research and development effort by the University of Notre Dame, the University of Wyoming, and Kraig Biocraft Laboratories Inc. has succeeded in producing transgenic silkworms capable of spinning artificial spider silks.
Less than half of essential workers willing to report to work during a serious pandemic
Although first responders willingly put themselves in harm's way during disasters, new research indicates that they may not be as willing -- if the disaster is a potentially lethal pandemic. In a recent study, researchers at Columbia University's Mailman School of Public Health found that more than 50 percent of the first responders and other essential workers they surveyed might be absent from work during a serious pandemic, even if they were healthy.
Free radicals can be anti-aging - says new research
A major blow to the free radical theory of aging, which had lead the research in aging for more than 50 years and fuels a multimillionaire anti-aging industry has just been published by Portuguese scientists from the University of Minho. The new work, shows that not only is possible to slow down aging in cells with high levels of oxidation but more, that a free radical (H2O2) is behind the high longevity seen with low caloric diets turning upside down the way we see anti-aging therapy and research with major implications for the field.
Research integrity: Sabotage!
Postdoc Vipul Bhrigu destroyed the experiments of a colleague in order to get ahead. It took a hidden camera to expose a surreptitious and malicious side of science.

New drug offers big relief for osteoarthritis pain
A phase II clinical trial of the first new type of drug for musculoskeletal pain since aspirin shows that it significantly reduces knee pain in osteoarthritis, the most common osteoarthritis pain, according to new research from Northwestern Medicine.
Evidence of post-stroke brain recovery discovered
The world's largest study using neuroimaging of stroke patients struggling to regain ability to communicate finds that brain cells outside the damaged area can take on new roles.
New study finds groups demonstrate distinctive 'collective intelligence' when facing difficult tasks
A new study co-authored by MIT, Carnegie Mellon University and Union College researchers documents the existence of collective intelligence among groups of people who cooperate well, showing that such intelligence extends beyond the cognitive abilities of the groups' individual members, and that the tendency to cooperate effectively is linked to the number of women in a group.
Virus-like particles speed bacterial evolution
The exchange of genetic information among ocean bacteria has been greatly underestimated.
Archaeologists shed new light on adaptability of modern humans` ancestors
A University of Otago-led archaeological investigation of campsites up to 50,000 years old in a remote highland valley of Papua New Guinea is revealing how highly adaptable the humans at the forefront of global colonisation were.

Brain chemical finding could open door to new schizophrenia drugs
New research has linked psychosis with an abnormal relationship between two signaling chemicals in the brain. The findings suggest a new approach to preventing psychotic symptoms, which could lead to better drugs for schizophrenia.
Parkinson's disease: Excess of special protein identified as key to symptoms and possible new target for treatment with widely used anti-cancer drug imatinib
Johns Hopkins scientists have discovered that the over-activation of a single protein may shut down the brain-protecting effects of a molecule and facilitate the most common form of Parkinson's disease.
The finding of this mechanism could lead to important new targets for drugs already known to inhibit it, thus controlling symptoms of the disorder, which affects about 1 million older Americans.
