Why So Many Earthquakes?
Haiti. Chile. California. China. Is there something unusual going on in the earth's crust, or is the recent spate of major earthquakes a statistical fluke? And do we have any way of predicting where the next one will hit? This week we ask Dr. Arthur Lerner-Lam, professor and researcher at the Earth Institute of Columbia University, who reveals what's shaking in the science of seismology.
According to Dr. Lerner-Lam, scientists can't "predict" earthquakes per se, but they can "forecast" them, and the technology is getting better all the time. So who should be worried? Well, definitely Seattle-ites—and they're already preparing. And the infamous "Big One" that California has feared all these years is no myth: in fact, the chances that it will happen in the next few decades are "close to 1, close to unity."
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.
