Last December, researchers from Johns Hopkins Applied Physics Lab delivered the arm to Matheny at his home in Port Richey, Florida. Aside from the occasional demo, this is the first time the Modular Prosthetic Limb (MPL) has spent significant time out of the lab.

SoFi isn't like other fish, but they don't seem to notice.

Pale and plump with a tail that swishes side-to-side, the one-eyed robotic fish was built by scientists at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL).

It is designed to swim naturally alongside other fish in open water and spy on them without raising suspicions or disturbing their natural habitat.

The un-tethered robot can use its camera to record behaviors of anything from sharks and whales to schools of tiny damselfish.

"With an instrument that does not impact the marine life, that is not scary or foreign to marine life, who knows what kind of magical and miraculous moments we can capture?" said Daniela Rus, director of CSAIL, who worked on the project. "[It] will give us a better understanding of underwater phenomena."

2 bears burned in California fire settle back into wild

  2 bears burned in California fire settle back into wild Officials tracking two bears that were badly burned in the largest wildfire in California history say the animals are settling back into their home in the wild after receiving unusual treatment for their injured paws. Recent photos and GPS tracking data show the female bears appear to be in good health as they move through Los Padres National Forest northwest of Los Angeles, news station KABC-TV reported Friday. The adult bears were released into the forest last month after getting care for third-degree burns they suffered in December's Thomas Fire. A mountain lion cub also was treated for singed paws. One bear was pregnant, but officials said last week that they weren't sure if the baby was born yet. Veterinarians treating the animals had stitched fish skins to their burned paws, then wrapped them with bandages of rice paper and corn husks. Officials decided on the treatment after reading about trials on human burn victims in Brazil that placed treated skins from tilapia, a ubiquitous species of fish, on the injuries to soothe pain and promote healing. Doctors routinely graft skin from humans and pigs to burns, but fish skins have the advantage of being more readily available. One of the bears initially would lie down continuously to spare her burned paws, said Jamie Peyton, chief of the integrative medicine service at the University of California, Davis' veterinarian school.

Scientists at MIT developed a robotic fish with a built-in camera to monitor other marine life.

The group, which includes Rus, Robert Katzschmann, Joseph DelPreto and Robert MacCurdy, introduced SoFi to the public on Wednesday in a new paper.

The researchers have taken the 18-inch-long faux fish for test swims in Fiji's Rainbow Reef, where it swam for up to 40 minutes in 50 feet of water.A diver directed the robot's movements from up to 32 feet away using a waterproofed Super Nintendo controller.

So far, SoFi doesn't appear to disturb the movements of other fish. According to Rus, it moves with a "grace, agility and independence" -- not what you'd expect from a swimming robot.

The outside of the robot is a combination of soft silicone rubber, flexible plastic and 3D-printed pieces. It uses a custom sound-based communication system developed by the team to receive movement instructions. The quiet motor-powered tail lets it mimic the quick-changing swimming patterns and movements of real fish. In addition, it touts sensors to help it avoid hitting or damaging marine environments like delicate reefs.

10 wolves killed in northern Idaho to boost elk numbers

  10 wolves killed in northern Idaho to boost elk numbers BOISE, Idaho — Federal officials have killed 10 wolves in northern Idaho at the request of the Idaho Department of Fish and Game to boost elk numbers, and state officials say more might be killed this winter.The U.S. Department of Agriculture's Wildlife Services said Wednesday that workers used a helicopter in the Clearwater National Forest in late February and early March to kill the wolves."At the request of Idaho, we did remove wolves in that region," said agency spokeswoman Tanya Espinosa.Idaho officials say the area's elk population in what's called the Lolo zone has plummeted in the last 25 years from about 16,000 to about 2,000, and that wolves are to blame along

While making it move like a fish was tricky, Rus said the most challenging part of the design process was buoyancy control, allowing it to smoothly move up and down in the water.

The CSAIL department has been working on underwater image and recording systems for more than seven years, but this is the first project that attempts to mimic the appearance and movements of fish so realistically.

The team intends to make SoFi even smarter so it can make decisions without a human diver feeding it instruction and move in a coordinated group of robot fish.

The researchers ultimately want to bring the tech to biologists, who could benefit from a new way of collecting data and observations about ocean life and the impacts of climate change.

Idaho wildlife officials approve limited grizzly bear hunt .
The Idaho Fish and Game Commission approved a limited hunting season for grizzly bears in eastern Idaho just a year after the animals were removed from the Endangered Species List. Under the plan, the Department of Fish and Game will hold a random drawing to award one Idaho hunter a grizzly tag for a hunting season running from Sept. 1 to Nov. 15.Neither baiting nor hound-hunting are allowed, and if successful, the hunter won't be allowed to reapply for future tags.Grizzlies in the Yellowstone National Park region were on the Endangered Species Act list until 2017, when the U.S.
