(credit: CDC) For the first time, researchers have discovered strains of a deadly, multidrug-resistant bacterium that uses a cryptic method to also evade colistin, an antibiotic used as a last-resort treatment. That’s according to a study of US patients published this week by Emory University researchers in the […]

There’s a last-resort ‘planet-hacking’ plan to make Earth habitable for longer — but scientists warn it could have dramatic consequences

One way to prevent the Earth’s temperature from rising into a city-drowning, hurricane-strengthening, heat-stroke–triggering danger zone is to immediately switch from fossil fuels to renewable energy sources. At the moment, that transition seems unlikely. So scientists and tech innovators are also investigating various forms of geoengineering — an approach that involves transforming the Earth’s clouds and skies in ways that […]
