New study of 1980s Mars meteorite debunks proof of ancient life on planet

Scientists who were part of original 1996 study stand by their observations claiming new findings are ‘disappointing’A four billion-year-old meteorite from Mars that caused a splash here on Earth decades ago contains no evidence of ancient, primitive Martian life after all, scientists have said.In 1996, a Nasa-led team announced that organic compounds in the rock appeared to have been left by living creatures. Other scientists were skeptical and researchers chipped away at that premise over the ...

Do we have to age?

The biologist Andrew Steele thinks ageing is a disease that can be treated. But if we had a cure for getting old, what would that mean for us?When the biologist Andrew Steele tells people his thoughts on ageing – that we might one day cure it as if it were any other disease – they are often incredulous and sometimes hostile. Once, at a friend’s wedding, he left a group of guests mildly incensed for suggesting that near-future humans might live well into their 100s. A similar thing happens at din...

Mars rover finds ancient organic compounds that match meteoritic samples

NASA's Curiosity Rover discovered 'tough' organic molecules on Mars, increasing the chances that a record of potential life could have been preserved despite harsh conditions that can easily break down organics. Carnegie's Andrew Steele was a key member of the research team, whose work on this project built off his discovery six years ago of indigenous organic carbon in Martian meteorites. The organic molecules he found in 2012 are comparable to those found by Curiosity.
