Matt Kason, a fungi researcher at West Virginia University, has discovered that cicadas whose bodies have been corrupted by the fungus Massospora keep flying around, have tons of energy and get really horny, because the fungus is doping them with meth and shrooms.

I asked Kasson if it’s possible to get high by eating Massospora-infected cicadas. Surprisingly, he didn’t say no. “Based on the ones we looked at, it would probably take a dozen or more,” he said. But it’s possible that earlier in the infections, before the conspicuous saltshaker stage, the fungus might pump out higher concentrations of these chemicals. Why? Kasson suspects that the drugs help the fungus control its hosts.
Infected cicadas behave strangely. Despite their horrific injuries, males become hyperactive and hypersexual. They frenetically try to mate with anything they can find, including with other males. They’ll even mimic the wing-flicking signals of females to lure males toward them. None of this does them any good—their genitals have either been devoured by the fungus or have fallen off with the rest of their butts. Instead, this behavior only benefits the fungus, allowing its spores to find new hosts.
Kasson suspects that cathinone and psilocybin are responsible for at least some of these behaviors. “If I had a limb amputated, I probably wouldn’t have a lot of pep in my step,” he said. “But these cicadas do. Something is giving them a bit more energy. The amphetamine could explain that.”
Psilocybin’s role is harder to explain.
The prohibition on psychedelics was memorably described as "the worst case of scientific censorship since the Catholic Church banned the works of Copernicus and Galileo" by former UK Drugs Czar David Nutt, and despite the ban, there has been a consistent, determined, very promising (sometimes surprising) drumbeat of scientific papers about the use of psilocybin ("magic mushrooms") and other psychedelics in treating a range of chronic illnesses, including mental illnesses.

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.
A "bad trip" on psychedelic mushrooms may lead to "enduring increases in well-being," according to a new study from Johns Hopkins University School of Medicine. Neuroscientist Roland Griffiths and colleagues surveyed nearly 2,000 adults about their psilocybin experiences. Those who experienced bad trips had taken, on average, a powerful dose of 4 grams. From Psypost:
A majority of the participants — 62 percent — said their bad trip was among the top 10 most psychologically difficult situations of their lives. Eleven percent said it was their number one most difficult experience.
But 34 percent of participants said the bad trip was among the top five most personally meaningful experiences of their life and 31 percent said it was the among the top five most spiritually significant. And 76 percent said the bad trip had resulted in an improved sense of personal well-being or life satisfaction. Forty-six percent said they would be willing to experience the bad trip all over again.

In the last decade, researchers at Johns Hopkins University and elsewhere have launched new studies investigating whether psychedelic drugs, from shrooms to LSD to DMT, can treat mental disorders ranging from depression and PTSD to anxiety and obsessive-compulsive disorder. Vox reporters German Lopez and Javier Zarracina surveyed the state of medical research on hallucinogens:
In a recent study, British researchers used brain imaging techniques to gauge how the brain looks on LSD versus a placebo. They found big differences between LSD and the placebo, with the images of the brain on LSD showing much more connectivity between different sections of the mind.
This can help explain visual hallucinations, because it means various parts of the brain — not just the visual cortex at the back of the mind — are communicating during an LSD trip.
This, researchers argued, may show not just why psychedelic drugs trigger hallucinogenic experiences but also why they may be able to help people. "In many psychiatric disorders, the brain may be viewed as having become entrenched in pathology, such that core behaviors become automated and rigid," the researchers wrote. "Consistent with their ‘entropic’ effect on cortical activity, psychedelics may work to break down such disorders by dismantling the patterns of activity on which they rest."
