Community characteristics play an important role in perpetuating teen suicide clusters and thwarting prevention efforts, according to a new study by sociologists at the University of Chicago and University of Memphis who examined clusters in a single town.

The study, published in the American Sociological Review, illustrates how the homogeneous culture and high degree of social connectedness of a community can increase suicide risk, particularly among teenagers. Such conditions contribute to clusters in which a series of suicides happen around the same time and in close proximity.

Men's hidden fears about body fat are fuelling gym attendance motivated by feelings of guilt and shame rather than a desire to build muscle, new research has shown.

Psychology researchers from the UK and Australia discovered that while male attitudes towards muscle or body mass index (BMI) did not predict how frequently they would attend the gym, their perceptions of body fat did.

The researchers found that men worried about body fat were more likely than others to undertake spontaneous, unplanned work-outs - and warned that these 'sporadic' exercise patterns tend to be difficult to sustain over time.

A University of Vermont-led team has successfully used social media images to measure the use and value of outdoor recreation on public lands.

The study analyzed more than 7,000 geotagged photos on Flickr to calculate that conserved lands contributed $1.8 billion to Vermont's tourism industry between 2007-2014.

The research is the first to measure of the value of outdoor recreation in Vermont public parks and other conserved lands during these years. The findings were published September 9 in the journal PLOS ONE.

Bacteria transfer to candy that has fallen on the floor no matter how fast you pick it up.  

Rutgers researchers have disproven the widely accepted notion that it's OK to scoop up food and eat it within a "safe" five-second window. Donald Schaffner, professor and extension specialist in food science, found that moisture, type of surface and contact time all contribute to cross-contamination. In some instances, the transfer begins in less than one second. Their findings appear online in the American Society for Microbiology's journal, Applied and Environmental Microbiology.

Several years ago, biologists discovered a new type of genetic material known as long noncoding RNA. This RNA does not code for proteins and is copied from sections of the genome once believed to be "junk DNA."

Since then, scientists have found evidence that long noncoding RNA, or lncRNA, plays roles in many cellular processes, including guiding cell fate during embryonic development. However, it has been unknown exactly how lncRNA exerts this influence.

A study by animal welfare specialists has provided new evidence that using electronic containment systems to restrict where pet cats venture does not result in long-term wellbeing problems.

The use of hand-held shock collars on dogs has previously led to concerns over the welfare of animals trained using so-called 'e-collars'. However, other forms of electronic training devices for pets have received relatively little attention from researchers. These include invisible or virtual fences which deliver a static electric pulse to deter animals from crossing a boundary, such as a garden perimeter.
