A number of koalas that were rescued during January's massive Australian wildfires were returned to the wild earlier this week, Science for Wildlife announced. The four adult koalas and a baby joey were returned to the Blue Mountains region of Australia. A total of 12 koalas were rescued and the group is working on returning all 12 this week. The San Diego Zoo was involved in rescuing and returning the koalas. The wildfires 2.5 million acres of Australian land. Experts estimate that nearly one-third of the koala population in Australia perished with the wildfires. 583

A new school year means tons of students are embarking on their first solo living experiences in college dorms around the country. But with that new responsibility comes great power — usually about 1100 watts of it.The Ball State University Police Department posted a hilarious reminder on their Facebook page telling students that the microwaves in their dorms do more than just warm snacks and reheat day-old coffee. They can also set off the fire alarms in the dorms."Every year starts with multiple fire alarms in Ball State Housing," Ball State Unviersity police posted on social media. "Most if not all of these fire alarms are preventable."They offered tips on how to heat up many college student staples, including Pop-Tarts, brownies, Kraft macaroni and cheese, oatmeal and popcorn.Pop-Tarts "must be removed from their aluminum foil prior to placing in the microwave," they wrote. "Microwave for 3 SECONDS not 3 minutes."They also gently reminded their Muncie, Indiana, students that brownies, mac and cheese and oatmeal usually need some kind of liquid added to them, whether it's milk or water.And, of course, they cited popcorn as the worst offender of setting off fire alarms unnecessarily. Students should "stay with your food," they said. "When you no longer hear the popping sound, stop the microwave. Overcooking causes scorching which causes fire alarms."Heed this warning, college kids. There's nothing more inconvenient than scorched food and an entire dorm of sleepy students glaring at you and your smoking popcorn. 1551

A tetraplegic man has been able to move all four of his paralyzed limbs by using a brain-controlled robotic suit, researchers have said.The 28-year-old man from Lyon, France, known as Thibault, was paralyzed from the shoulders down after falling 40 feet from a balcony, severing his spinal cord, the AFP news agency reported.He had some movement in his biceps and left wrist, and was able to operate a wheelchair using a joystick with his left arm.Researchers from the University of Grenoble in France, biomedical research center Clinatec and the CEA research center implanted recording devices on either side of Thibault's head, between the brain and skin, to span the sensorimotor cortex -- the area of the brain that controls motor function and sensation.Electrode grids collected the man's brain signals and transmitted them to a decoding algorithm, which translated the signals into movements and commanded a robotic exoskeleton to complete them.Over a period of two years, Thibault trained the algorithm to understand his thoughts by controlling an avatar -- a virtual character -- within a video game, making it walk and touch 2D and 3D objects.He trained on simple virtual simulations before using the exoskeleton -- which is assisted by a ceiling-mounted harness -- to eventually walk, and reach for targets with his arms.Over the course of the study, Thibault covered a total of 145 meters (around 476 feet) with 480 steps using the avatar, video and exoskeleton combined, researchers said in the study, which was published in 1549
