From driving cars to beating chess masters at their own game, computers are already performing incredible feats.
And artificial intelligence is quickly advancing, allowing computers to learn from experience without the need for human input. But scientists are concerned that computers are already overtaking us in their abilities, raising the prospect that we could lose control of them altogether.

Scientists believe they have found a way to treat and perhaps reverse Parkinson’s disease, by making replacement cells to mend the damaged brain. They say human brain cells can be coaxed to take over the job of the ones that are destroyed in Parkinson’s.
Tests in mice with Parkinson-like symptoms showed that the therapy appeared to ease the condition. Many more studies are needed before similar…

The perilous history of a penguin colony on a small Antarctic island has been recorded in their excrement. For thousands of years, the birds have nested on the Ardley outcrop where their poop, or guano, would collect at the bottom of a lake. But when scientists drilled into these sediments, they got quite a surprise.

Mars’ atmosphere is full of metal, potentially explaining how the planet became uninhabitable, according to new results from a NASA probe published Monday.
NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) found metal ions capable of showing how the planet’s upper atmosphere behaves. Mars doesn’t have a global magnetic field like Earth, preventing metal ions from being locked into…
