New studies unravel mysteries of how PARP enzymes work
(From left) Dr. Ziying Liu, Keun Woo Ryu, Dr. W. Lee Kraus, and Dr. Xin Luo led research studies that focused on how PARP enzymes function. A component of an enzyme family linked to DNA repair, stress responses, and cancer also plays a role in enhancing or inhibiting major cellular activities under physiological conditions, new...

U.S. science advisory committee supports genetic modification of human embryos
Embryos could soon be edited—but there are some caveats. Ever since CRISPR—the relatively cheap and easy-to-use genome editing technique—made its way to the scientific stage, researchers have grappled with one of its biggest ethical quagmires: Its ability to edit human embryos, thereby potentially altering the DNA of subsequent generations. The question of whether to allow such a...
