Toronto – We like to think we'd stick to our ethical principles no matter what. But when people feel financially deprived -- as many did from losses suffered thanks to the last market and banking meltdown -- they are more likely to relax their moral standards and transgress to improve their financial situation. They are also more likely to judge other deprived moral offenders who do the same more leniently, says a new paper to be published in Organizational Behavior and Human Decision Processes.

Patients with bladder cancer are two times more likely to have complications after a radical cystectomy procedure if they have a biomarker for poor nutritional status before the operation, according to study findings presented last week at the 2013 Clinical Congress of the American College of Surgeons. Surgeons from the University of North Carolina at Chapel Hill School of Medicine and UNC Lineberger Comprehensive Cancer Center identified a potentially modifiable risk factor for such postsurgical problems: a low preoperative level of albumin, a marker of the protein level in the blood.

PRINCETON, NJ—In the forests of Ecuador, plain-tailed wrens nest in bamboo thickets, singing complex and continuous melodies. Residing nearby are rufous antpittas, small, secretive birds that hop like thrushes and whistle in mossy forests. Together, their songs fill parts of the South American Andes.

Birdwatchers often seek out rare and beautiful birds like the wren and antpitta using "playbacks" – or recordings of bird songs – to draw such them out from their hideaways. But does such babbling-on-repeat harm the birds?

Oxford, October 16, 2013 - There has been an intense research interest in all two-dimensional (2D) forms of carbon since Geim and Novoselov's discovery of graphene in 2004. But as the number of such publications rise, so does the level of inconsistency in naming the material of interest. The isolated, single-atom-thick sheet universally referred to as "graphene" may have a clear definition, but when referring to related 2D sheet-like or flake-like carbon forms, many authors have simply defined their own terms to describe their product.

New research shows that cuckoos have striped or "barred" feathers that resemble local birds of prey, such as sparrowhawks, that may be used to frighten birds into briefly fleeing their nest in order to lay their parasitic eggs.

October 16, 2013, Shenzhen, China---A Chinese research team composed of Shenzhen Second People's Hospital, BGI and other institutes reports their latest study on bladder cancer genomics that was published online in Nature Genetics.

The actual aim of the study was to find out whether cats are more stressed when they live in large groups together or, whether the strict hierarchy of larger groups reduces stress. Neither could be confirmed in the present study, which was published in the journal Physiology & Behavior. The number of cats per household had no influence on the stress of the animals. Rather, stress in domestic cats depends more on the socialization of the animals, on the relationship with humans, on the space available to them or on the access to food.

With 30 million indwelling bladder catheters placed annually nationwide, patients face an increased risk of developing catheter-associated bacteriuria (bacteria in the urine). Many patients with indwelling urinary catheters acquire bacteria in the urinary tract while they are catheterized. Most previous studies assessing morbidity and mortality associated with catheter use have not separated urinary tract infection from asymptomatic bacteriuria. This has made it difficult to determine if bacteria in the urine puts patients at higher risk for bloodstream infection or death.

For a long time, it was thought impossible to isolate a pearl's genetic material. Now, a Swiss research team has achieved this elusive goal. Scientists Joana Meyer, from the ETH Institute of Integrative Biology group headed by Prof. Bruce McDonald, and Laurent Cartier of the Swiss Gemmological Institute (SSEF), under the direction of Michael Krzemnicki, succeeded for the first time in extracting trace amounts of DNA from a variety of cultured pearls in an almost non-destructive way.

Despite the common fear that those annoying tip-of-the-tongue moments are signals of age-related memory decline, the two phenomena appear to be independent, according to findings published in Psychological Science, a journal of the Association for Psychological Science.

The survey provides the most robust prevalence measure to date - and identifies abnormal prion protein across a wider age group than found previously and in all genotypes.

An accompanying editorial says that although the disease remains rare, "infection" may be relatively common and doctors need to understand the public health measures that are in place to protect patients.

Professor Clare Bambra and Dr Alison Copeland from Durham University argue that "the more affluent, healthier south east will benefit most and the poorer, less healthy north will lose out substantially." And they urge worried BMJ readers to respond to the consultation.

NHS funding is allocated to areas on the principle of providing "equal opportunity of access for equal need," they explain. To help achieve this, the current NHS allocation formula incorporates a deprivation related measure, known as the "health inequality weighting."

BOSTON (15 October 2013) – Today, the Population Council presented findings from a Phase 3 clinical trial that was designed to demonstrate the safety, efficacy, and acceptability of the Council's investigational one-year contraceptive vaginal ring (CVR). The results were presented during an oral session at the 69th Annual Meeting of the American Society of Reproductive Medicine.

Vitelliform macular dystrophy, also known as Best disease, is one of a group of vision-robbing conditions called bestrophinopathies that affect children and young adults. Caused by inherited mutations in the BEST1 gene, these diseases cause severe declines in central vision as patients age.

With a new study, University of Pennsylvania researchers report "encouraging" findings that mark the first clear step in developing a gene therapy that could prevent vision loss or event restore vision in individuals suffering from these conditions.

During the U.S.-led invasion and occupation of Iraq from 2003 to 2011, for every three people killed by violence, two died as a result of the collapse of the infrustructure that supports health care, clean water, nutrition, and transportation, according to new estimates in a study from the University of Washington Department of Global Health published Oct. 15 in the open access journal PLOS Medicine. All told, the researchers estimate nearly a half million people died from causes that could be attributed to the war.
