Sealing The Deal
An underwater photographer was shocked when a leopard seal tried to feed him a live penguin.
"Bloody hell! That’s the biggest sea leopard I’ve ever seen," cried photographer Paul Nicklen. "Leopard seals are pretty scary predators, especially if you're a penguin. But they can be friendly to other leopard seals, which is something that Paul learned during one of his trips to Antarctica. He was taking underwater photos when a leopard seal started feeding him penguins, starting with live ones, which were released close to him (to see if he would catch them), and ending with half-chewed dead ones. One theory is that the leopard seal saw his reflection in the lens of the camera and thought that Nicklen was a fellow predator, but an awkward one in need of some help. This went on for four days – and there are some great photos."
Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
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.
