The psilocybin in magic mushrooms is a potent psychedelic for animals. But what good is the psilocybin for the shrooms? New genetic research from Ohio State University suggests that the psilocybin might act as an insect repellant, protecting the mushrooms. From New Scientist:
The gene cluster (linked to psilocybin production) is found in several distantly related groups, suggesting that the fungi swapped genes in a process called horizontal gene transfer. This is uncommon in mushrooms: it is the first time genes for a compound that is not necessary for the fungi’s survival – called a secondary metabolite – have been found moving between mushroom lineages.
Since these genes have survived in multiple species, Slot thinks psilocybin must be useful to the fungi. “Strong selection could be the reason this gene cluster was able to overcome the barriers to horizontal gene transfer,” (researcher Jason Slot) says.
Hallucinogenic mushrooms often inhabit areas rich in fungi-eating insects, so Slot suggests psilocybin might protect the fungi, or repel insects from a shared food source, by somehow influencing their behaviour.
The Bank of England has unveiled its new £50 notes, which had been earmarked to honour a distinguished British scientist, and which will feature Alan Turing, the WWII hero who discovered many of the foundational insights to both modern computing and cryptography, and whose work with the codebreakers of Bletchley Park are widely believed to […]
The great science purge, they’ll call it one day. Donald Trump is closing science offices throughout the federal government. ‘As of June, around 85 percent of all scientific posts in the federal government, including an official scientific advisor to the President, were left unfilled,’ write the editors of I F***ing Love Science blog in an […]
Ed Hawkins, a climate scientist, created Show Your Stripes as a way to easily visualize the past century's climate change: give it a location and it will render a series of stripes representing a century's worth of average annual temperatures (above: global average temperature); as Kottke notes: "The warming patterns for particular regions are not […]
With the rising temperatures on tap this summer, the climate is going to be a frequent topic of conversation, and those conversations won’t be happy ones. Luckily, there’s a way to do a little climate change of your own – in a safe and sustainable way. When it comes to personal air conditioners, EvaPolar is […]
Whether you’re using them for next-level selfies or steady tracking shots, gimbals are a must for anyone who wants to maximize the potential of these powerful smartphone cameras we’re all carrying around. But those smartphones are also supposed to be portable, and let’s face it: Gimbals tend to offset that advantage. Weighing in at just […]
It’s too hot for yard sales, but hey: The internet is here for you. Here are the top ten deals on some of the Boing Boing Store’s best gear, just in time for summer. It’s everything from grills to security cameras to MacBook Pros, and they might be as low as they’re ever going to […]
