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.

This image shows induced pluripotent stem cells expressing a characteristic cell surface protein called SSEA4 (green).
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.

96 percent of marine species, and 70 percent of terrestrial life died off in the Permian-Triassic extinction event, as geologists know it. It is also known as The Great Dying Event for obvious reasons.

Atomic resolution studies of two common calcium channel blockers, one that treats irregular heart beats, and another that controls high blood pressure and angina
An atomic level analysis has revealed how two classes of calcium channel blockers, widely prescribed for heart disease patients, produce separate therapeutic effects through their actions at different sites on the calcium channel molecule.

This is an illustration of warbler.
For decades, conservationists have considered blue-winged warblers to be a threat to golden-winged warblers, a species being considered for federal Endangered Species protection. Blue-winged warbler populations have declined 66 percent since 1968, according to the North American Breeding Bird Survey.

This is a fossil ptilodactyline beetle found in amber from Mexico. The black arrow points to pollinia attached to the beetle's mouthparts.
When most people hear the word "pollinator," they think of bees and butterflies. However, certain beetles are known to pollinate plants as well, and new fossil evidence indicates that they were doing so 20 million years ago.

Squinting won't help you spot the fish in this photo. These snub-nosed darts blend seamlessly into their watery surroundings with help from their silvery reflective skin.
In a matchup of animal superpowers, a clever form of camouflage might beat super sight -- at least in the ocean.

A single thymic epithelial cell (red) in contact with developing T cells (white).
Researchers at the universities of Basel and Oxford have for the first time identified all genes regulated by the protein Foxn1. The results show that Foxn1 not only plays a crucial role in development of the thymus in the embryo, but it also regulates vital functions in the developed, postnatal organ. The decryption of the protein's functions is important in the understanding and treatment of autoimmune diseases, vaccination responses in old age and defense against tumor cells. The study was published in the journal Nature Immunology.
