Austrian scientists are putting the ‘fun’ in ‘fungus’ by forcing organisms which are usually asexual to have sex instead.

The hope is that the fungus would then be easier to breed, which would allow researchers to create organisms that are more efficient at degrading cellulose for the purpose of making biofuel.

How do you save dying species of agriculturally valuable plants and animals?  The answer may be as simple as what’s on your dinner plate.

A recent article outlined the “eat ‘em to save ‘em” method of biodiversity protection.  Simply put, rare varieties of plants and animals can be saved if consumers demand them.  Asking your grocer, chef, or farmers market vendor about heirloom and endangered varieties is a great way to demonstrate that the demand exists for these diverse crops.

A major infestation of the mountain pine beetle, a scourge stretching from New Mexico, in the U.S., to British Columbia, Canada, has been turning vast areas of formerly green pine forests to rust red, and slowly killing them.

The beetle infestation has been growing “exponentially” since 2006-07, according to the Forest Service management team in Laramie, Wyoming, and has so far claimed millions of acres of pine forest in Montana, Colorado, and Wyoming. North of the border, British Columbia has already lost over 33 million acres of lodgepole pine forest due to the ravages of this type of bark beetle. And more recently (in 2008), Alberta province is come under threat due to an aberrant wind storm that apparently lofted the beetles across the continental divide.

Draws upon a recent news reports in Science about the stem rust fungus, Ug99, that is sweeping the globe and threatening to decimated the world’s wheat harvests. Also, the politics behind some nation’s reluctance to give full access of their seed banks (which may possess genetic varieties of these crops that can withstand this and other diseases) to other nations.

Honey bees are disappearing. The story has been in the news on and off since 2006, but for one reason or another, most people have paid little attention. And the situation is significantly dire.

The setting for this discovery sounds like something out of a Dr. Seuss book. A fungus that grows in Ulmo trees in the Patagonian Rainforest is the source of a significant discovery.

“This is the only organism that has ever been shown to produce such an important combination of fuel substances,” said Professor Gary Strobel from Montana State University. “The fungus can even make these diesel compounds from cellulose, which would make it a better source of biofuel than anything we use at the moment.”

Like many scientific breakthroughs, scientists stumbled upon this discovery by accident.

“Gliocladium roseum lives inside the Ulmo tree in the Patagonian rainforest. We were trying to discover totally novel fungi in this tree by exposing its tissues to the volatile antibiotics of the fungus Muscodor albus. Quite unexpectedly, G. roseum grew in the presence of these gases when almost all other fungi were killed. It was also making volatile antibiotics. Then when we examined the gas composition of G. roseum, we were totally surprised to learn that it was making a plethora of hydrocarbons and hydrocarbon derivatives. The results were totally unexpected and very exciting and almost every hair on my arms stood on end!”

American scientists have discovered a fungus deep in the Patagonian rainforest that makes biodiesel as part of its natural lifecycle. The fungus is the only organism that has ever been shown to produce such an important combination of fuel sources.

According to team member Prof. Gary Strobel of Montana State University, “The fungus can even make these diesel compounds from cellulose, which would make it a better source of biofuel than anything we use at the moment.”

That fungus among us may be the answer to uranium-polluted soils eventually being brought back into use.

Researchers at Dundee Unversity in the UK have determined that fungi can block uranium from finding its way into plants, animals or the water supply.

Scientists have found that what they call free-living and plant fungi can, “colonise depleted uranium surfaces and transform the metal into uranyl phosphate minerals”.
