How To Build a Space Elevator
Using very little energy, a 62,000-mile-high space elevators could carry travelers out of earth's gravity well and up to a spaceship dock. It could be tomorrow morning's commute.
A space elevator is a fairly simple concept. It would be made of an ultra-strong metal ribbon that stretches from a mobile base in the ocean at the Earth's equator, up thousands of miles into space, attaching at its other end to an "anchor" in geostationary orbit. Robotic climbers rush up the ribbons, pulling cars full of their cargo—human or otherwise. Because the space elevator pulls cargo out of our gravity well, rather than pushing it using combustion, it would save a lot of energy and be capable of bringing far more materials offworld quickly.
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.
