New jellyfish robots can outswim their inspiration

New jellyfish robots can outswim their inspiration

Science
July 2 (UPI) -- Engineers have developed soft-bodied robots that can outswim their biological inspiration -- jellyfish. The jellyfish robots, described this week in the journal Advanced Materials Technologies, were engineered with pre-stressed polymers, a new method that lends strength to soft-bodied robots. Advertisement "Our previous work focused on making soft robots that were inspired by cheetahs - and while the robots were very fast, they still had a stiff inner spine," Jie Yin, an assistant professor of mechanical and aerospace engineering at North Carolina State University and corresponding author on the newly published paper, said in a news release. "We wanted to make a completely soft robot, without an inner spine, that still utilized that concept of switching between two stable ...

Jellyfish map could help conservationists protect marine ecosystems

Science
Jan. 16 (UPI) -- By analyzing the chemical composition of jellyfish caught across a sizable swath of the Atlantic, scientists can map important differences among an array of marine habitats. The analysis technique could offer important insights to ecologists and conservationists -- a new tool for protecting the health of important fisheries. According to a new study published this week in the journal Methods in Ecology and Evolution, chemical signals measured in jellyfish reflect the chemistry, biology and physical processes unique to the region where they were caught. "The chemical differences detected in the jellyfish are also present in other animals throughout the food chain, like seabirds, seals and fishes," Katie St. John Glew, researcher at the University of Southampton, said in a ...
