Heart Health Benefits with Weightlifting, Findings

Lifting weights for less than an hour a week may reduce your risk for a heart attack or stroke by 40 to 70%, according to a new study. Spending more than an hour in the weight room did not yield any additional benefit, the found researchers. The results show benefits of strength training are independent of running, walking or other aerobic activity.

Implantable Medical Devices: Cotton-based Hybrid Biofuel Cell Power It

A glucose-powered biofuel cell that uses electrodes made from cotton fiber could someday help power implantable medical devices such as pacemakers and sensors. The new fuel cell, which provides twice as much power as conventional biofuel cells, could be paired with batteries or supercapacitors to provide a hybrid power source for the medical devices.

Cancer Research: New Virus Eqipped that Kills Carcinoma Cells with Protein

Scientists have equipped a virus that kills carcinoma cells with a protein that can also target and kill adjacent cells that are tricked into shielding cancer from the immune system. It is the first time that cancer-associated fibroblasts within solid tumors – healthy cells that have been tricked into protecting cancer from the immune system and supplying it with growth factors and nutrients – have been specifically targeted in this way.

More Insights on Gonorrhea, a STD

Johns Hopkins researchers are spearheading efforts to raise awareness and learn more about a sexually transmitted disease few people know about but scientists believe makes people infertile. Many people infected with mycoplasma genitalium , or Mgen for short, do not show symptoms and might not know they are carrying the disease. There's no approved test for it, which makes it difficult to track, but doctors believe it's more common than gonorrhea, infecting about 1 to 3 percent of the population.

Infant Microbiome Development: Study Finds Three Distinct Stages

In the largest clinical microbiome study in infants reported to date, researchers explored the sequence of microbial colonization in the infant gut through age 4 and found distinct stages of development in the microbiome that were associated with early life exposures. Published in the journal Nature, their report and an accompanying report led by the Broad Institute are the result of extensive analysis of data collected from a cohort of participants involved in the TEDDY diabetes study.
