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.

A study led by Loyola Medicine researchers found that female triathletes are at higher risk for pelvic floor disorders, among other health issues.

The study, published in Female Pelvic Medicine and Reconstructive Surgery, found that female triathletes suffered from a high rate of stress urinary and anal incontinence.

"We expected the high rates of urinary incontinence, but did not expect to find such high rates of anal incontinence," said senior author, Colleen Fitzgerald, MD, MS. Dr. Fitzgerald is the medical director of the Chronic Pelvic Pain program and an associate professor in the department of obstetrics and gynecology at Loyola University Chicago Stritch School of Medicine.

You soon won't have to judge a book by its cover, you'll be able to judge through it. Researchers writing in Nature Communications describe a prototype of an imaging system that can read closed books. They tested on a stack of papers, each with one letter printed on it. The system was able to correctly identify the letters on the top nine sheets.

Three out of four (75 percent) people in the UK are unaware of the link between obesity and cancer, according to a new Cancer Research UK report. The nationwide survey found that people from lower socioeconomic backgrounds are less likely to know about the link. And men are less likely than women to be aware of the increased risk of cancer caused by obesity.
