Weekly: Claims that secret alien technology is held in the US; link between gut bacteria and intelligence; the parasite that makes ants live longer
New Scientist Weekly #200
Always trust your gut! A recent study shows that the composition of our gut microbiome may be directly linked to our overall intelligence, with certain bacteria, perhaps, influencing brain size; other bacteria, not so much. Alexandra Thompson discusses these remarkable findings with the team.
Cephalopods have some extraordinary capabilities, and new research conducted by Joshua Rosenthal at Woods Hole Marine Biological Laboratory in Massachusetts reveals that they can even edit their genetic material in order to survive changes in their environment. Amid these findings, Rowan and Clare wonder if gene editing is linked to octopus intelligence…
The secret to a longer life? A parasitic worm - if you are an ant, at least. Parasitologists have discovered a tapeworm that invades its host ant, allowing the latter to live at least three times longer, all whilst being fed and cared for by its uninfected friends. The worm’s ultimate goal, however, is somewhat less appealing.
Just say no? So-called ‘smart drugs’ such as Ritalin are widely prescribed to those suffering from ADHD. They’re also sometimes used by people seeking a mental boost. But as Clare informs Rowan, unless prescribed, Ritalin probably won’t do you any good.
Former US intelligence official David Grusch claims that the US government has retrieved alien spacecraft and is harbouring the bodies of extraterrestrials which piloted it. But the team shares a healthy dose of scepticism.
On the pod are Rowan Hooper, Clare Wilson, Alexandra Thompson, Leah Crane and Michael Le Page. To read about these subjects and much more, you can subscribe to New Scientist magazine at newscientist.com.
