Magnetism from underwater power cables doesn’t deter sea life
High-voltage power cables that ferry electricity across the seafloor do not negatively impact local fish and crabs, new studies show.

Corals need to take their vitamin C
Newly settled corals use vitamin C to help build their stony skeletons, researchers propose.
- Neuroscience
Brain cells aglow after viral delivery
The virus AAV-PHP.B proves best at delivering genes to brain cells in mice. Similar viruses may eventually be used for gene therapy in humans.
- Animals
