Jumping the gun ?!?
In their desperate drive to be the first to claim a discovery and to secure future funding by sheer amount of headlines - knowing full well how the ignorami in the MSM and the public would interpret the report and, worse, its possible refutation (*) - they jumped the gun.
With all due respect, I'm afraid there is some irony here:
If you had bothered to check ALL the facts available to you (as in reading the original article of which the above is a verbatim quote), you would have seen that scientific rigour indeed applies, moreover, the new discussion doesn't yet dispel the idea, it seeks to improve accuracy - the matter is not as "simple" as the original team envisaged as there are more variables to address.
I would agree that there is huge competition in any scientific field and not always for the right reasons, but in this case it's fact checking and refining theories, and I'm quite happy it takes place.
Hats off to all.
