High folic acid and low B12 can affect fetal brain development in mice

Folate is a B vitamin and a necessary nutrient to prevent neural tube defects, such as spina bifida. Folic acid, a synthetic form of folate, has been added to vitamins, breakfast cereals, and other products in the U.S. and more than 80 other countries to ensure pregnant women get adequate amounts. However, new research suggests there may be such a thing as too much folic acid.

Radiation therapy takes advantage of cancer’s poor DNA repair abilities. Experts explain how

Nearly half of all cancer patients undergo radiation therapy as part of their care. Ionizing radiation, or the emission of high-energy waves or particles, works as a therapy by damaging a cancer cell’s DNA. It’s an effective tool for killing cancer cells because they are generally much less adept at DNA repair compared to healthy cells. Damaging specific parts of DNA prevents cancer cells from reproducing, effectively killing them.
