In 2006, a patent was granted to a man named Paul Stamets. Though Paul is the world’s leading mycologist, his patent has received very little attention and exposure. Why is that? Stated by executives in the pesticide industry, this patent represents “the most disruptive technology we have ever witnessed.” And when the executives say disruptive, they are referring to it being disruptive to the chemical pesticides industry.http://www.ecosnippets.com/environmental/patent-that-could-destroy-monsanto/
What has Paul discovered? The mycologist has figured out how to use mother nature’s own creations to keep insects from destroying crops. It’s what is being called SMART pesticides. These pesticides provide safe & nearly permanent solution for controlling over 200,000 species of insects – and all thanks to the ‘magic’ of mushrooms.

Pterosaurs were the first vertebrate creatures to evolve powered flight and conquer the air—long before birds took wing. They prevailed for more than 160 million years before vanishing along with the nonbird dinosaurs at the end of the Cretaceous period, around 66 million years ago. In that time, they evolved some of the most extreme anatomical adaptations of any animal, living or extinct. The smallest of these aerial predators was the size of a sparrow. The largest had a wingspan that rivaled that of an F-16 fighter jet. Many possessed heads larger than their bodies, making them, in essence, flying jaws of death. Pterosaurs patrolled every ocean and continent on Earth. No animal in the Mesozoic would have been safe from their gaze.#Palaeontology #Reptiles #Pterosaurs #Evolution #Biology
Unlike dinosaurs, which are survived today by birds, pterosaurs left behind no living descendants. As a result, all that paleontologists know about pterosaurs comes from the fossil record. And that record has been frustratingly fragmentary, leaving us with just a glimmer of their former glory and a host of questions about their bizarre anatomy and ill fate. Paleontologists have scratched their heads over these mysteries for decades. Now new fossil discoveries, combined with mathematical modeling methods in which anatomical structures are simplified just enough that equations of physical properties can be applied to get best estimates of strength, weight, speed, and so forth, are finally generating insights. And what scientists are finding is that pterosaurs were even more extraordinary than we ever imagined.
A man in China who, after eating high-carbohydrate or sugary meals, became so intoxicated that he blacked out, has led researchers to discover strains of bacteria in the human gut that could be an important driver of the world’s most common liver disease.#Science #Biology #Bacteria #Microbiomes
Doctors previously had diagnosed the man’s intoxication problem as autobrewery syndrome, a rarely reported condition in which people become drunk from starchy or sugary foods. It is thought to be caused by gut fermentation, aided by an abundance of yeast. But antifungal treatment had no effect on the man. Liver biopsies showed he had nonalcoholic steatohepatitis (NASH), the severe form of NAFLD. He was moved to the intensive care unit and closely observed. Doctors noted that after he ate a meal high in sugar, his blood alcohol level rose to as high as 400 milligrams per deciliter. “That’s equivalent to 15 shots of 40% [80-proof] whisky,” Yuan says.
Because some other microbes can metabolize sugars into alcohol, Yuan and colleagues analyzed 14 of the man’s stool samples taken at different times for species-specific bacterial DNA fragments. They found that when he was most intoxicated, 18.8% of the bacteria in a sample were K. pneumoniae, a 900-fold increase over normal. When they put these bacteria in a medium of yeast and sugar, they could isolate strains of the bacterium that produced high, medium, or low levels of alcohol.
Yuan and colleagues report that the initial patient they studied recovered from his bacteria-driven autobrewery syndrome after he began to take antibiotics and changed his diet. His NASH has abated, too. Her team is now planning to study the gut microbes of a large group of people, including children, over time. “We want to investigate why some people have high-alcohol-producing strains of K. pneumoniae in their gut while others don’t,” she says.
Diehl cautions that the new study speaks only to a subset of NAFLD patients. But she predicts “this will work will attract a lot of attention.”
There are between five million and six million insect species worldwide, and scientists have described about one million of them. Of these, only one, the Antarctic midge, is able to survive at the bottom of the planet. Purplish, wriggly and the size of a pinkie fingernail clipping, Antarctic midge larvae live for nearly two years underground, often near penguin and seal excrement. They spend over half of their lives, about eight months of the year, frozen.#Nature #Biology #Insects #Environment #Antarctica
Nicholas Teets, who leads the Insect Stress Biology Lab at the University of Kentucky, published an article last month in the Journal of Experimental Biology that reveals how Antarctic midge larvae are able to survive such extremes. By better understanding the processes at work, scientists hope that the Antarctic midges’ survival strategies — including dehydration and freezing — might have applications for the preservation of human tissues, such as organs harvested for transplants.
