British scientists exploring an underwater mountain in the Atlantic Ocean have discovered a treasure trove of rare minerals. Their investigation of a seamount more than 500km (300 miles) from the Canary Islands has revealed a crust of "astonishingly rich" rock.
Samples brought back to the surface contain the scarce substance tellurium in concentrations 50,000 times higher than in deposits on…

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.
