2014 Mental Health Conference: A Global Focus.
Homeless, mentally ill women face vicious cycle in India
An award-winning study has documented how homeless, mentally ill women in India face a vicious cycle: During psychotic episodes, they wander away from home, sometimes for long distances, and wind up in homeless shelters. They then are returned to their families before undergoing sufficient psychosocial rehabilitation to deal with their illness. Consequently, they suffer mental illness relapses and wind up homeless again.

Why do people with autism see faces differently?
The way people with autism spectrum disorder gather information - not the judgement process itself -- might explain why they gain different perceptions from peoples' faces, according to a new study from Hôpital Rivière-des-Prairies and the University of Montreal.

A link between DNA transcription and disease-causing expansions
Scientists have believed that the lengthening of those repeats occur during DNA replication when cells divide or when the cellular DNA repair machinery gets activated. Recently, however, Tufts scientists have discovered another process called transcription, which is copying the information from DNA into RNA, could also been involved.

Vegetable oil ingredient key to destroying gastric disease bacteria
The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers at University of California, San Diego School of Medicine and Jacobs School of Engineering developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils. In mice, LipoLLA was safe and more effective against H. pylori infection than standard antibiotic treatments.

Centipede's genome reveals how life evolved on our planet
Centipedes have been genetically sequenced for the first time by an international team of over 100 scientists. Study co-author professor Ariel Chipman at the Hebrew University of Jerusalem says the humble arthropod's DNA gives scientists new insight into how life developed on our planet. The creature independently evolved solutions to the problem of living on land by losing some genes and expanding other gene families not present in insects.

Physicists bind single-atom sheets with the same force geckos use to climb walls
The approach is to design synergistic materials by combining two single-atom thick sheets, for example, that act as a photovoltaic cell as well as a light-emitting diode, converting energy between electricity and radiation.

Long-term testosterone therapy does not increase the risk of prostate cancer
Testosterone (T) therapy is routinely used in men with hypogonadism, a condition in which diminished function of the gonads occurs. Although there is no evidence that T therapy increases the risk of prostate cancer (PCa), there are still concerns and a paucity of long-term data. Investigators examined three parallel, prospective, ongoing, cumulative registry studies of over 1,000 men. Their analysis showed that long-term T therapy in hypogonadal men is safe and does not increase the risk of PCa.

Mining can damage fish habitats far downstream, study shows
Anglers across the nation wondering why luck at their favorite fishing spot seems to have dried up may have a surprising culprit: a mine miles away, even in a different state. Scientists at Michigan State University have taken a first broad look at the impacts of mines across the country and found that mining can damage fish habitats miles downstream, and even in streams not directly connected to the mines.

Athletes' testosterone surges not tied to winning, study finds
A higher surge of testosterone in competition, the so-called 'winner effect,' is not actually related to winning, suggests a new study of intercollegiate cross country runners.

A hybrid vehicle that delivers DNA
A new hybrid vehicle is under development. Its performance isn't measured by the distance it travels, but rather the delivery of its cargo: vaccines that contain genetically engineered DNA to fight HIV, cancer, influenza and other maladies. Described in the Proceedings of the National Academy of Sciences, the technology could help unleash the potential of DNA vaccines, which despite two decades of research, have yet to make a significant impact in the treatment of major illnesses.

Researchers shed new light on the genetics of memory performance
In the largest study of the genetics of memory ever undertaken, an international researcher team including scientists from Boston University School of Medicine, have discovered two common genetic variants that are believed to be associated with memory performance. The findings, which appear in the journal Biological Psychiatry, are a significant step towards better understanding how memory loss is inherited.

Superbug in SE Michigan shows recent decline
A new study finds a decrease in an emergent strain of methicillin-resistant S. aureus (MRSA) that is resistant to last line defense antibiotics. Researchers examined the prevalence of vancomycin-resistant Staphylococcus aureus (VRSA) infections in southeastern Michigan, where the majority of these infections have occurred in the US. The study is published in the December issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

Using wash cloths in jails shows promise for reducing costly infections
New research shows providing detainees wash cloths treated with a skin cleanser could reduce the prevalence of S. aureus bacteria in US jails. Researchers looked at the effect of using wash cloths treated with chlorhexidine gluconate compared with wash cloths with only plain water in detainees at Dallas County Jail. The study was published in the December issue of Infection Control and Hospital Epidemiology, the journal of SHEA.

Virtual money: User's identity can be revealed much easier than thought
Bitcoin is the new money: minted and exchanged on the Internet. Faster and cheaper than a bank, the service is attracting attention from all over the world. But a big question remains: are the transactions really anonymous? Researchers at the University of Luxembourg have now demonstrated how the IP address behind each transaction can be revealed with only a few computers and about €1500.

Why fruit flies could lead to better beer (video)
Your beer may attract annoying fruit flies, but listen up before you give them a swat. Researchers found the yeast cells in beer are producing odor compounds -- acetate esters -- that lure flies and that could lead to the best beer you haven't even tasted yet. This week's Speaking of Chemistry explains why. Check it out at

Feeling -- not being -- wealthy drives opposition to wealth redistribution

Study maps how city neighborhoods affect diabetes risk
Ground zero for identifying ways to stop the rise in diabetes prevalence is Philadelphia, which has the highest diabetes rate among the nation's largest cities. Public health researchers at Drexel University looked at how neighborhood and community-level factors -- not just individual factors like diet, exercise and education -- influence people's risk. Their new study adds insight into the role of the physical and social environment on diabetes risk, zip code by zip code throughout the city.

NIH scientists determine how environment contributes to several human diseases
Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers. The work, appearing online Nov. 17 in the journal Nature, provides a possible explanation for how one type of DNA damage may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer's disease.

Body size requires hormones under control
In a study now published in the scientific journal eLife, a research group from Instituto Gulbenkian de Ciência, led by Christen Mirth, shed new light on how animals regulate body size. The researchers showed that the timing of synthesis of a steroid hormone called ecdysone is sensitive to nutrition in the fruit fly and described the key proteins involved in this regulatory mechanism. This study explains what causes hormones to become environmentally-sensitive.
