Algae-powered soft robot arm uses light to grasp and lift small objects‎

Tiny underwater algae sway gently in the current. All of a sudden, a light shines on them and they form robotlike arms that start to pick up small rocks and put them in floating baskets. Sounds like science fiction, but researchers from Delft University of Technology (the Netherlands) have created a small soft robot arm covered with minuscule algae that can grasp and lift objects. And it's powered by light. This next step in biotechnology has been published in Nature Communications.

Baby manta rays hunker down close to coasts before facing the open ocean's dangers‎

Giant manta rays can grow up to nine meters (30 feet) long with a disk size of seven meters (23 feet) across and weigh up to 2,000 kg (4,400 pounds). This size leaves them with very few natural enemies once they reach adulthood at around eight to 10 years old. But giant manta ray babies, called pups, cannot rely on their size to protect them from predators that live in the open ocean, including several species of shark and orcas.

Illegal fishing is thriving in African waters—a satellite system could help change that‎

This is one of West and Central Africa's largest marine reserves, where industrial trawling is banned. None of the trawlers held a valid license. The patrol found them because analysts at the nonprofit Global Fishing Watch had studied satellite data and worked out where to look.
