Yes. We drill into the earth to mine for gas, oil and minerals and construct massive dams and, as a result, have caused at least 200 quakes of more than 4.5 magnitude in the past 160 years, says Christian Klose, a researcher at Columbia University who studies man-made quakes.
Brain-machine interfaces hold potential for a variety of ends, from helping the neurologically or physically disabled communicate and interact with their environments, to creating thought-controlled computers that augment the brain with computing power. A group of researchers at Columbia are turning that model on its ear, using brain power to augment computing tasks. Their device couples the human brain and computers to perform tasks neither could do as efficiently on their own.
The loss of a tooth is a minor deformity and a major pain. Although dental implants are available, the healing process can take months on end, and implants that fail to align with the ever-growing jawbone tend to fall out. If only adult teeth could be regenerated, right?
According to a study published in the latest Journal of Dental Research, a new tissue regeneration technique may allow people to simply regrow a new set of pearly whites.
