3-D models reveal hidden details of zebrafish behavior
In the first experiments of their kind, researchers found significant discrepancies in data generated when tracking the social behavior of zebrafish in two dimensions as opposed to 3-D. Although the researchers say the cost of 3-D tracking is too expensive to replace 2-D studies, it could significantly reduce the number of fish needed for laboratory experiments.

After receiving bad advice, bullying victims say they would give same bad advice to others
Targets of workplace bullying get plenty of advice from coworkers and family on how to respond to the situation and make it stop. While well intentioned, much of the advice victims receive is impractical or only makes their situation worse. Despite the bad advice, most victims said they would tell others in their situation to do the same thing. (Source: ScienceDaily Headlines)

Inflammatory signature of nonalcoholic fatty liver disease
A team of investigators has identified key inflammatory cells involved in nonalcoholic fatty liver disease. Current treatment for the disorder involves changes to diet, yet no medication has been approved for treatment. Findings from this study provide a potential therapeutic target and offer the possibility for developing a treatment. (Source: ScienceDaily Headlines)

An immunity gene evolved in Southeast Asia to protect against leprosy
A mutation in an immune system gene rapidly rose in frequency in Southeast Asia approximately 50,000 years ago because it likely conferred protection against leprosy. The findings show that the gene variant, called HLA-B*46:01, encodes a protein that binds to molecules derived from the bacterium that causes leprosy. This HLS protein then presents these foreign molecules to the immune system, which destroys the infected cells. (Source: ScienceDaily Headlines)

3-D printed ovaries produce healthy offspring
3-D printed bioprosthetic mouse ovaries restored fertility in infertile mice and produced healthy mouse pups. The mothers also were able to nurse their pups. The research is targeted to women whose cancer treatments impaired their fertility and hormone production. The ovaries are constructed of 3-D printed scaffolds that house immature eggs and were successful in boosting hormone production and restoring fertility. (Source: ScienceDaily Headlines)

Photoreceptor cell death leads to blindness in CLN5 form of Neuronal Ceroid Lipofuscinosis
Researchers have discovered a likely cause for visual impairment and eventual loss of vision in the Finnish variant of Neuronal Ceroid Lipofuscinosis (NCL). Visual impairment associated with the Finnish variant of NCL may be caused by impaired retinal waste management system, including autophagy, leading primarily to the death of photoreceptor cells that are of essential for vision.

Warm weather increases the incidence of serious surgical site infections
Surgical site infections, a common healthcare-associated infection, are seasonal -- increasing in the summer and decreasing in the winter-according to new research. Temperatures above 90 °F were associated with 28.9 percent increased odds for hospitalization with a surgical site infection (SSI) compared to temperatures less than 40°F.
