Artificial intelligence pioneer says we need to start over

The search for planets beyond our solar system will be taken up by the Transiting Exoplanet Survey Satellite, a new NASA spacecraft scheduled to launch in the first half of the year that will focus on finding exoplanets around bright stars and those close to Earth. Its predecessor -- NASA's Kepler missions -- discovered more than 2,500 confirmed exoplanets, including two recently spotted with artificial intelligence. Researchers plan to use machine learning to scour more data from Kepler in search of planets that may have been overlooked. Last year, a small number of young patients were treated for cancer with gene-edited cells, and the first gene editing was done directly in the body of a patient with the metabolic disease Hunter's syndrome. "Every single study will look at what they did and will [try to] follow suit," says Fyodor Urnov, associate director of Altius Institute of Biomedical Sciences.
