'Obesity genes' may influence food choices, eating patterns
Blame it on your genes? Researchers say individuals with variations in certain "obesity genes" tend to eat more meals and snacks, consume more calories per day and choose the same high fat, sugary foods....

Resilient people more satisfied with life
When confronted with adverse situations such as the loss of a loved one, some people never fully recover from the pain. Others, the majority, pull through and experience how the intensity of negative emotions (e.g. anxiety, depression) grows dimmer with time until they adapt to the new situation. A third group is made up of individuals whose adversities have made them grow personally and whose life takes on new meaning, making them feel stronger than before....

Phthalates in PVC floors taken up by the body in infants
Phthalates from PVC flooring materials is taken up by our bodies, according to new research. Phthalates are substances suspected to cause asthma and allergies, as well as other chronic diseases in children. The study shows that children can ingest these softening agents with food but also by breathing and through the skin....

Uproar over prostate-cancer screenings explained
Despite recent recommendations from the US Preventive Services Task Force, many people simply don't believe that the prostate-specific antigen test is ineffective. Even faced with overwhelming evidence, many activists and medical professionals are clamoring for men to continue receiving their annual PSA test. Why the disconnect? A new article examines the reasons why people are so reluctant to give up the PSA test....

Scientists unravel role of fusion gene in prostate cancer
Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein -- but no one has known how that alteration promotes cancer growth....

Rapid DNA sequencing may soon be routine part of each patient's medical record
Rapid DNA sequencing may soon become a routine part of each individual's medical record, providing enormous information previously sequestered in the human genome's 3 billion nucleotide bases. Recent advances in sequencing technology using a tiny orifice known as a nanopore are covered in a new a article....

Role of fusion gene in prostate cancer: Mutation found in half of all prostate cancers may lead to disease development
Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein — but no one has known how that alteration promotes cancer growth. Now, researchers have found that in these cancer cells, the 3-D architecture of DNA, wrapped up in a little ball known as a chromatin, is warped in such a way that a switch has been thrown on thousands of genes, turning them on or off to promote abnormal, unchecked growth. Researchers also found that new chromosomal translocations form, further destabilizing the genome....

Wrongful convictions can be reduced through science, but tradeoffs exist
Many of the wrongful convictions identified in a report this week hinged on a misidentified culprit -- now, scientific research reveals the paradox of reforms in eyewitness identification procedure. In our efforts to ensure good guys don't get locked up, we could let more bad guys go. Scholars in psychology and law debate aspects of eyewitness identification procedures, providing a scientific foundation for this important social issue....

New anti-cancer drug developed
Scientists have created a new type of anti-cancer drug named BP-1-102. The drug, which can be orally administered, targets a key protein that triggers the development of many types of cancer including lung, breast and skin cancers. The development of BP-1-102 was guided by the research teams computer based molecular analysis of the cancer causing Stat 3 protein....
