The Guardian: If aliens contact humanity, who decides what we do next?
If there is consensus that the signal is legit, researchers should inform the public and the secretary general of the UN.
But there is little guidance on what to do next. How should the message be studied? Should it be released in full before it has been deciphered? Would governments allow that? Should humanity respond? If so, who decides what we send back?

Koriander: pfui Teufel
Wikipedia: OR6A2
Variation in the OR6A2 gene has been identified as a likely cause of why some people enjoy the smell and taste of coriander (also known as cilantro) while others have exactly the opposite reaction to the point of repulsion. Depending on ancestry, somewhere between 3% and 21% of the population associate it with unpleasant taste, including a combination of soap and vomit, or say that it is similar to the foul smelling odor emitted by stinkbugs.

Ars Technica: No, physicists didn’t make a real wormhole. What they did was still pretty cool
"It’s not the real thing; it’s not even close to the real thing; it’s barely even a simulation of something-not-close-to-the-real-thing," physicist Matt Strassler wrote on his blog. "Could this method lead to a simulation of a real wormhole someday? Maybe in the distant future. Could it lead to making a real wormhole? Never. Don’t get me wrong. What they did is pretty cool! But the hype in the press? Wildly, spectacularly overblown."
