The Kentucky Department of Fish and Wildlife Resources is using electrofishing techniques to do battle against the invasive Asian carp. Since their introduction in the 1970s, Asian carp populations have exploded in the Mississippi, Illinois, and Missouri rivers. The carp take over feeding grounds from native fish, sending them into a steep decline. The department is also investing in bio-acoustic fish fences that will use bubbles, sound and light to keep the carp from spreading to new areas.

For the first time, doctors in the U.S. have used the powerful gene-editing technique CRISPR to try to treat a patient with a genetic disorder. It probably will take months, if not years, of careful monitoring of Gray and other patients before doctors know whether the treatment is safe and how well it might be helping patients.

Imperial College London scientists have created artificial cells that mimic biological cells by responding to a chemical change in their surroundings.The artificial cells could be used to sense changes in the body and respond by releasing drug molecules, or to sense and remove harmful metals in the environment.
