Health-conscious folks have long sprinkled savory nutritional yeast flakes — a vegan version of parmesan cheese — on popcorn, pasta, salad, and more for an umami-rich punch. But consumers should be aware that this condiment, affectionately known as "nooch," sometimes functions like a supplement. What is nutritional yeast? Nutritional yeast is an inactivated strain of the fungus Saccharomyces cerevisiae.

The brain extends from the skull and touches the outside world in only one place: the phyllo-like layers of retinal cells that line the back of the eye. Like their brethren in the brain, these delicate light sensors cannot be replaced; if they die, vision is lost.

Whether it’s a jog through the park or a weight lifting session in a sweaty gym, exercise fosters good health. Compared to remaining sedentary, regular movement associates with a 20-30 percent lower risk of dying from all causes.1However, exercise causes mechanical stress in skeletal muscles; this, along with microinjuries, can spark mild inflammation.

The retina is layered with photoreceptors, a variety of other neurons, and protective and structural membranes, but retinal disorders can tamper with this delicate system. Mutations in the Crumbs homolog 1 (CRB1) gene disrupt the integrity of retinal membranes, leading to the gradual loss of photoreceptors. CRB1 mutations associate with multiple retinal diseases, including Leber congenital amaurosis and retinitis pigmentosa.

Cells in the human body are made to move. They assemble during embryo development, migrate to repair tissue, hunt pathogens, and perform a host of other tasks requiring travel. As part of the cytoskeleton, actin filaments help maintain a cell’s shape, but they also help the cell move and divide. They do much of this by treadmilling, a process in which actin monomers are added to one end of the filament and removed from the other end.

Three floors below Dmitriy Sheyn’s lab at Cedars-Sinai Medical Center, doctors remove degenerated intervertebral discs from patients with severe back pain. Instead of tossing the old discs, however, they sometimes give them to one of Sheyn’s lab members, who rushes them upstairs to harvest the fresh cells. The patients in these operating rooms accepted surgery because they were suffering, but many people with degenerated discs feel no pain at all. Sheyn wanted to know why.

CRISPR-Cas holds great promise for treating and curing human disease. One of the few ways that scientists can usher CRISPR elements into a large number of mammalian cells is via an adeno-associated viral (AAV) vector. These vectors are small, so squeezing the large Cas enzyme gene plus its promoters, the polyadenylation signal, guide RNA genes, and other needed components into one vector is difficult; splitting the components into two vectors can create problematic doses or reduce the efficiency.
