Lab notes: is there life on exoplanets orbiting Trappist-1?

Ok, so it may not be as catchy as Bowie's musings on Mars, but it's certainly as thrilling: with the discovery of seven Earth-sized planets orbiting nearby star Trappist-1, hopes have been raised that the hunt for alien life beyond the solar system could start within the next decade. That should give us time to sort out the bot-on-bot editing wars that have broken out on Wikipedia, and train bumblebees not merely to score goals for sugar, but to sort out the NHS as well or something. Let's not look too far ahead though, as it turns out that most people would rather avoid knowing their future. On a more serious note, researchers have discovered that long-winded speech could be early sign of Alzheimer's disease, and suggest that subtle changes in speech style occur years before more serious mental decline takes hold. Given that life expectancy is forecast to exceed 90 years in coming decades, early interventions for health conditions will be welcome, although one thing it seems you can do to protect your health is up your fruit and veg intake to 10 portions a day. Do crisps count?
