Elon Musk, founder of SpaceX and Tesla Motors, unveiled his designs for Hyperloop. The high-speed transit system could make the 400-mile trip from San Francisco and Los Angeles in 30 minutes. Tim De Chant, senior digital editor at NOVA, discusses the plans and whether the system could answer our transit problems.

China says it plans to phase out the harvesting of organs from executed prisoners, ending a controversial practice that reportedly supplies most of the country's transplant patients.
Huang Jiefu, a surgeon and former deputy health minister who is in charge of organ transplants, says that beginning in November, China will scale back and eliminate the harvesting of inmate organs. Huang says that will be replaced by a nationwide voluntary donor system.
Looking back at history and prehistory, privacy is the rarest luxury. It requires walls or seclusion. It is not our natural condition.
In recent times people have taken privacy for granted, the same way we take other modern conveniences for granted. There's nothing natural about privacy, just as there is nothing inalienable about cheap fast food.
There's some sad news from NASA: The space agency says its Kepler space telescope is beyond repair.
The $600 million planet-hunting probe whose mission was to search other solar systems for Earth-like planets has lost its ability to keep its gaze on target.
Two of the four gyroscope-like reaction wheels that keep Kepler pointed in the right direction have broken down and can't be fixed, but NASA is still hoping it can find some less-stressful work for the orbiting observatory.
Oklahoma was hit particularly hard by two massive outbreaks this year in what's been another deadly season of tornadoes in the U.S. Despite technology and forecasting improvements, scientists still have plenty to learn about how and why tornadoes form.
Currently, one of the best ways for researchers to understand how tornadoes form is to chase them. So off they go with mobile science laboratories, rushing toward storms armed with research equipment and weather-sensing probes.
Scientists have just solved a case of mistaken identity. It involves a creature that looks like a cross between a house cat and a teddy bear, and it lives high up in the cloud forests of the Andes.
For over 100 years, scientists thought this animal was a well-known member of the raccoon family. Specifically, they thought it was a critter called the "olingo." But one scientist recently took another look and realized he had an entirely new species on his hands.
What happens in our brains while we're asleep? That's one question neuroscientist Penelope Lewis is trying to answer. She directs the Sleep and Memory Lab at the University of Manchester in England. Her new book is The Secret World of Sleep: The Surprising Science of the Mind at Rest.
Lewis joins Fresh Air's Terry Gross to talk about how sleep affects memory, and how REM sleep can affect depression.
