Mapping the white-footed deer mouse genome could lead to Lyme vaccine
Scientists who sequenced the genome of the white-footed deer mouse and compared it to other mouse genomes report in Science Advances that differences in gene expressions associated with hair follicles and skin might encourage the growth of Borrelia burgdorferi bacteria, which causes Lyme disease, on the skin, where it is easily picked up by ticks. The genomic map could help scientists develop a vaccine or a way to prevent the bacteria from growing on the species, says study coauthor Anthony Long.

Scientists at Texas Biomedical Research Institute are studying FDA-approved drugs that could help adults remain healthy and independent as they age. One study is testing the effects in marmosets of a drug for organ transplant patients that appears to improve kidney function and cognitive decline, and another is testing a cancer drug that may improve cognitive decline and impairment of motor skills in baboons.

Treatment shows promise in mouse models of fatal childhood disease
An antibody-enzyme fusion showed promise in mouse models of Lafora disease, an inherited, fatal type of pediatric epilepsy for which no effective treatment exists. LD is marked by the aggregation of toxic carbohydrates resembling plant starch in the brain, and a fused amylase antibody virtually eliminated the aggregates, called Lafora bodies, in mouse brains and other tissues.

Researchers found that a combination of two gene-editing techniques in patient-derived cells with severe hemophilia A restored factor VIII levels while reducing bleeding episodes in mice. While the case involves a specific mutation, the work "provides a reference for the repair of other gene mutations," the authors wrote in the journal Molecular Therapy - Nucleic Acids.

Weight training appears to have neuroprotective effect in rats
A study involving rats that was published in the Journal of Applied Physiology suggests weight training improves brain plasticity and encourages genetic activity, contributing to cognitive ability and potentially reducing or reversing some age-related memory loss. Weight training is "good for you for all kinds of other reasons, and it appears to be neuroprotective," study leader Taylor Kelty said.

Southern white rhino born at San Diego Zoo gives conservationists hope
A healthy male southern white rhinoceros was born at San Diego Zoo after 493 days' gestation and 30 minutes of labor. The mother rhino was artificially inseminated after ovulation was induced, and the successful birth may help efforts to restore the population of the critically endangered northern white rhino, says San Diego Zoo Global's reproductive science director Barbara Durrant.

Antibody added to cat food may ease human allergies
Adding an antibody to cat food may reduce the amount of allergy-causing protein Fel d1 that's secreted by the felines and which causes allergy symptoms in humans. The study was published in Immunity, Inflammation and Disease.

NIH connecting dots between disparate datasets
The NIH launched the $17.5 million Biomedical Data Translator program in 2016 to create a Google-type search engine that can mine myriad data sources and help researchers spot patterns. Scientists at 19 institutions are integrating data from EHRs, genomic sequences and other sources across disparate platforms, applying new machine learning tools to organize and make connections between seemingly unrelated data, and developing tools to make use of the results.
