"It's like an invisibility cloak but with the exception that we are splitting the object, the visual silhouette, into smaller bits," Hart said. The study's authors released a video showing some of the research in action. Ryan said the results were better ...

Dr. Laura Ryan of Macquarie University explains that lights on the underside of surfboards distort the silhouette, making it less appetizing to sharks.

Scientists have discovered that equipping surfboards with bright LED lights could prevent great white shark attacks on surfers and swimmers. A recent study published in the journal Current Biology found that lighting up the underside of surfboards disrupts the silhouette perceived by sharks - so they are less likely to mistake humans for their usual prey.
