DNA smeared on a rocket survives re-entry and tells of life's origins

Nicely, would you take a look at that: scientists have found that DNA could make it by way of the hellish ordeal of atmospheric re-entry in any case. German and Swiss researchers dotted a rocket’s grooves and screw heads with fragments of genetic blueprints to see how they’d fare in conditions that would’ve led to the looks of life on Earth. Scientific American notes that the thirteen-minute rocket journey won’t completely characterize how DNA may truly journey from one celestial physique to the subsequent (that’d be by meteor), however there’s objective right here. What the experiment suggests is that even when the meteor’s been scorched, that the fabric can survive at larger temperatures than beforehand anticipated, and as such this paints a greater image of simply how resilient DNA is. What’s subsequent? Pushing the bounds additional and seeing precisely what it takes to kill the double helix — we’re fairly positive at the least one rock band is itching to seek out out.
