These devices use an electric field to scare sharks from fishing hooks

SharkGuard gadgets work by harnessing sharks’ ability to detect electric fields. That could save the animals’ lives, a study suggests.

Climate

Wind turbines could help capture carbon dioxide while providing power

Turbulent wakes from wind turbines can concentrate CO₂ from cities and factories, making it easier to remove the greenhouse gas from the atmosphere.

Tree-climbing carnivores called fishers are back in Washington’s forests

Thanks to a 14-year reintroduction effort, fishers, or “tree wolverines,” are once again climbing and hunting in Washington’s forests after fur trapping and habitat loss wiped them out.

Climate

Climate change could turn some blue lakes to green or brown

As temperatures rise, more than 1 in 10 of the world’s blue lakes could change color, reflecting holistic shifts in lake ecosystems.

Climate

Gas flares are leaking five times as much methane than previously thought

The flares burn off methane at 91 percent efficiency. Achieving 98 percent efficiency would be like taking nearly 3 million cars off the road.
