‘Jumping genes’ help stabilize DNA folding patterns

“Jumping genes” — bits of DNA that can move from one spot in the genome to another — are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of Medicine in St. Louis indicates that such genes, also called transposable elements, play another, more surprising role: […]

A new role for neurogenesis

The ability to create new neurons may exist as built-in protection for sensitive brain areas, according to research in mice recently published in JNeurosci. For a quarter of a century, scientists have known that the brain creates new neurons even into adulthood—a process called adult neurogenesis. The question has been: why? Adult neurogenesis occurs in […]

Why can’t Bertrand Might cry? Scientists offer an answer: missing water channels

Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that cells from children with NGLY1 deficiency—a rare disorder first described in 2012—lack sufficient water channel proteins called aquaporins. The discovery was published in Cell Reports and may help explain the disorder’s wide-ranging symptoms—including the inability to produce tears, seizures and developmental delays—and opens new […]
