Researchers identify physiological evidence of 'chemo brain'
Chemotherapy can induce changes in the brain that may affect concentration and memory, according to a new study. Using positron emission tomography combined with computed tomography, researchers were able to detect physiological evidence of chemo brain, a common side effect in patients undergoing chemotherapy for cancer treatment.

New studies show effects of mammography guideline changes
Researchers assessing the impact of revised guidelines for screening mammography issued by the US Preventive Services Task Force found evidence that the new recommendations may lead to missed cancers and a decline in screening, according to two new studies.

Women with dense breasts welcome additional screening
A survey of women undergoing routine screening mammography found that many of them would be interested in pursuing additional screening tests if notified they had dense breast tissue, despite the possibility of false positives, invasive procedures, and out-of-pocket costs, according to a new study.

Breast cancer risk estimates increased with repeated prior ct and nuclear imaging
Researchers reviewing the records of approximately 250,000 women enrolled in an integrated healthcare delivery system found that increased CT utilization between 2000 and 2010 could result in an increase in the risk of breast cancer for certain women, including younger patients and those who received repeat exams. According to the study, nuclear medicine examinations may also contribute to increased breast cancer risk.

Scatter radiation from mammography presents no cancer risk
The radiation dose to areas of the body near the breast during mammography is negligible, or very low, and does not result in an increased risk of cancer, according to a new study. The results suggest that the use of thyroid shields during mammography is unnecessary.

4 common antipsychotic drugs found to lack safety and effectiveness in older adults
In older adults, antipsychotic drugs are commonly prescribed off-label for a number of disorders outside of their Food and Drug Administration-approved indications -- schizophrenia and bipolar disorder. The largest number of antipsychotic prescriptions in older adults is for behavioral disturbances associated with dementia, some of which carry FDA warnings on prescription information for these drugs.

New behavioral strategies may help patients learn to better control chronic diseases
Physicians should take a serious look at tools and strategies used in behavioral economics and social psychology to help motivate their patients to assert better control over chronic diseases. Breaking large goals into smaller, more manageable parts, for example, may help patients better manage diseases such as diabetes.

Cassini finds a video gamers' paradise at Saturn
You could call this "Pac-Man, the Sequel." Scientists with NASA's Cassini mission have spotted a second feature shaped like the 1980s video game icon in the Saturn system, this time on the moon Tethys. (The first was found on Mimas in 2010). The pattern appears in thermal data obtained by Cassini's composite infrared spectrometer, with warmer areas making up the Pac-Man shape.

Newly insured patients may have trouble finding primary care physicians
A study by researchers at the Mongan Institute for Health Policy at Massachusetts General Hospital finds that a significant percentage of the primary care physicians most likely to care for newly insured patients may be not be accepting new patients. The investigators note that strategies designed to increase and support these "safety-net" physicians could help ensure that newly covered patients have access to primary care.

IU-led team uncovers process for chameleon-like changes in world's most abundant phytoplankton
An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the world's most abundant ocean phytoplankton, once known as blue-green algae, to maximize light harvesting for photosynthesis.

Study links improved consumer welfare to increased prescription drug advertising efforts
More people are better off thanks to the impact of an influx of direct-to-consumer advertising spending than they would be without those marketing efforts, according to a study recently published by Jayani Jayawardhana in the University of Georgia College of Public Health. The multi-year study focused on advertising efforts surrounding cholesterol-reducing prescription medications. Jayawardhana found increased levels of consumer welfare due to direct-to-consumer advertising than when compared to situations without this type of marketing.

Rapid changes in climate don't slow some lizards
One tropical lizard's tolerance to cold is stiffer than scientists had suspected. A new study shows that the Puerto Rican lizard Anolis cristatellus has adapted to the cooler winters of Miami. The results also suggest that this lizard may be able to tolerate temperature variations caused by climate change.

Genome decoded: Scientists find clues to more disease-resistant watermelons
Juicier, sweeter, more disease-resistant watermelons could be on the way. An international consortium of more than 60 scientists from the United States, China and Europe has published the genome sequence of watermelon -- Citrullus lanatus -- that could dramatically accelerate watermelon breeding toward production of a more nutritious, tastier and more resistant fruit.

Study advances use of stem cells in personalized medicine
Johns Hopkins researchers report concrete steps in the use of human stem cells to test how diseased cells respond to drugs. Their success highlights a pathway toward faster, cheaper drug development for some genetic illnesses, as well as the ability to pre-test a therapy's safety and effectiveness on cultured clones of a patient's own cells.

Penn researchers make flexible, low-voltage circuits using nanocrystals
Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications in a world where electronics are becoming more pervasive. Finding materials with the right mix of performance and manufacturing cost, however, remains a challenge. Now researchers from the University of Pennsylvania has shown that nanoscale particles, or nanocrystals, of the semiconductor cadmium selenide can be "printed" or "coated" on flexible plastics to form high-performance electronics.

To get the best look at a person's face, look just below the eyes, according to UCSB researchers
They say that the eyes are the windows to the soul. However, to get a real idea of what a person is up to, according to UC Santa Barbara researchers Miguel Eckstein and Matt Peterson, the best place to check is right below the eyes. Their findings are published in the Proceedings of the National Academy of Sciences.
