European scientists have successfully connected a touch-sensitive prosthetic hand to an amputee which he is able to control using thought.
European scientists have successfully connected a touch sensitive prosthetic hand to an amputee which he is able to control using thought. "The experiment lasted a month, and scientists say it was the first time a patient has been able to make complex movements using his mind to control a biomechanic hand connected to his nervous system. The Italian-led team said at a news conference Wednesday in Rome that last year it implanted electrodes into the arm of the patient who had lost his left hand and forearm in a car accident. The prosthetic was not implanted on the patient, only connected through the electrodes. During the news conference, video was shown of 26-year-old Pierpaolo Petruzziello as he concentrated to give orders to the hand placed next to him. ‘It's a matter of mind, of concentration,’ Petruzziello said. ‘When you think of it as your hand and forearm, it all becomes easier.’"
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
