Cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) and Mercury are detected in sharks from the Atlantic and Pacific Oceans.
In a new study, University of Miami (UM) scientists found high concentrations of toxins linked to neurodegenerative diseases in the fins and muscles of 10 species of sharks. The research team suggests that restricting consumption of sharks can have positive health benefits for consumers and for shark conservation, since several of the sharks analyzed in the study are threatened with extinction due to overfishing.

Researchers at Houston Methodist have developed an artificial intelligence (AI) software that reliably interprets mammograms, assisting doctors with a quick and accurate prediction of breast cancer risk. According to a new study published in Cancer (early online Aug. 29), the computer software intuitively translates patient charts into diagnostic information at 30 times human speed and with 99 percent accuracy.

A research team including developmental biologist Stephen A. Duncan, D. Phil., SmartStateTM Chair of Regenerative Medicine at the Medical University of South Carolina (MUSC), has found a better way to purify liver cells made from induced pluripotent stem cells (iPSCs). Their efforts, published August 25, 2016 in Stem Cell Reports, will aid studies of liver disease for the National Heart, Lung, and Blood Institute (NHLBI)'s $80 million Next Generation Genetic Association Studies (Next Gen) Program. The University of Minnesota (Minneapolis) and the Medical College of Wisconsin (Milwaukee) contributed to the study.
