g.o.d. in mushrooms and they are f'ing amazing

The Ascender | The Macro of Myco
Reaching the lush science campus involved heading south from Delhi, just over the state border, along the trash-strewn Faridabad Road. The alkaline fields of dust along the side of the highway are poisonous to most plants, hospitable only for patches of the most rugged and ragged of species. Cars honked, buffalos labored, and I coughed. A fence loomed along the left side, opposite a temple and a rundown snack stand. On the other side of that fence, scientists were mass-producing spores that are rescuing broken down lands just like this one.
The auto rickshaw was still sputtering as I stepped out. I handed the driver some rupees and walked up the driveway to the guarded gates of The Energy and Resources Institute. As I stepped through TERI’s fence line, I took in the spectacle of an oasis. To my left was a gleaming green golf course. Caddies stirred, mistaking my interest for that of a golfer. A guard told me cricket ovals were off to the right, past the trees and the solar panel-covered parking lot. Ahead was a wide path that disappeared into jungle.
Somebody ought hand me a drink with a miniature umbrella.
Out of the shadows of the jungle appeared an electric buggy. Internal combustion engines are banned on the campus. The buggy ferried me quietly down the path and through the half mile of acacia trees, gardens, bamboo and rows of palm trees to Alok Adholeya’s laboratory on the other side.
If green-thumbed people ever got together to vote on who had the greenest thumb, this guy might win. The microbiologist is a maestro of mycorrhizae – the name given to an ancient subterranean union between fungi and plants.
“What you see here is all reclaimed land,” Adholeya said proudly, welcoming me to his research station of more than a quarter of a century.

curious, curious... magnetite implicated in Alzheimer's

Lancaster University | Toxic air pollution nanoparticles discovered in the human brain
[Editor's note: now why would a magnetic particle get lodged in and around neurons?]
Tiny magnetic particles from air pollution have for the first time been discovered to be lodged in human brains– and researchers think they could be a possible cause of Alzheimer’s disease.
Researchers at Lancaster University found abundant magnetite nanoparticles in the brain tissue from 37 individuals aged three to 92-years-old who lived in Mexico City and Manchester. This strongly magnetic mineral is toxic and has been implicated in the production of reactive oxygen species (free radicals) in the human brain, which are associated with neurodegenerative diseases including Alzheimer’s disease.
Professor Barbara Maher, from Lancaster Environment Centre, and colleagues (from Oxford, Glasgow, Manchester and Mexico City) used spectroscopic analysis to identify the particles as magnetite. Unlike angular magnetite particles that are believed to form naturally within the brain, most of the observed particles were spherical, with diameters up to 150 nm, some with fused surfaces, all characteristic of high-temperature formation – such as from vehicle (particularly diesel) engines or open fires.
The spherical particles are often accompanied by nanoparticles containing other metals, such as platinum, nickel, and cobalt.

beta test - zika pesticide killing bees

The Guardian | US beekeepers fear for livelihoods as anti-Zika toxin kills 2.5m bees
Huddled around their hives, beekeepers around the south-eastern US fear a new threat to their livelihood: a fine mist beaded with neurotoxin, sprayed from the sky by officials at war with mosquitos that carry the Zika virus.
Earlier this week, South Carolina beekeepers found millions of dead honey bees carpeting their apiaries, killed by an insecticide. Video posted by a beekeeper to Facebook showed thousands of dead insects heaped around hives, while a few survivors struggled to move the bodies of fellow bees.
“This is what’s left of Flowertown Bees,” a despondent keeper says in the video. Company co-owner Juanita Stanley told the Associated Press her farm looked “like it’s been nuked” and estimated 2.5 million bees were killed.
In another Facebook post, South Carolina hobbyist Andrew Macke wrote that he had lost “thousands upon thousands of bees” and that the spraying had devastated his business. “Have we lost our mind,” he wrote, “spraying poison from the sky?”
Around the US, bees and other pollinators contribute an estimated $29bn to farm income. Clemson University’s department of pesticide regulation is investigating the incident.
The program head, Dr Mike Weyman, said that though South Carolina has strict rules about protecting pollinators, county officials were using the neurotoxin, Naled, under a clause exempting them in a “clear and public health crisis”.
