By Robert Sanders, UC Berkeley The demise of the world's forests some 250 million years ago likely was accelerated by aggressive tree-killing fungi triggered by global climate change, according to a new study by a University of California, Berkeley, scientist and her Dutch and British colleagues. The researchers do not rule out the possibility that today's changing climate could cause a similar increase in pathogenic soil bacteria that could devastate forests already stressed by a warming...

Researchers led by Montana State University have found a surprising condition that occurs in the lungs after an invasion of a common mold that can cause deadly infections in humans. In the most oxygen-rich environment in the body "“ the lungs "“ the scientists discovered a shortage of oxygen. The shortage resulted from inflammation and invasive growth of the mold, which greatly reduced the oxygen available to the pathogenic mold Aspergillus fumigatus. The mold is generally found...

Many medical devices, ranging from artificial hip joints to dentures and catheters, can come with unwelcome guests "“ complex communities of microbial pathogens called biofilms that are resistant to the human immune system and antibiotics, thus proving a serious threat to human health. However, researchers may have a new way of looking at biofilms, thanks to a study conducted by University of Iowa biologist David Soll and his colleagues published in the Aug 2 issue of the online, open...

Rice "“ which provides nearly half the daily calories for the world's population "“ could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, just-published U.S. Geological Survey-led research shows. In an effort to explore ways to increase the adaptability of rice to climatic scourges such as tsunamis and tidal surges that have already led to rice shortages, USGS researchers and their...

North Carolina State University researchers have found that a subset of fungus-farming ambrosia beetles may be in the early stages of a global epidemic threatening a number of economically important trees, including avocados, poplars and oaks. "Only about 12 species of ambrosia beetle are creating problems so far, but there are thousands of other species in the world, many of which could be devastating to any number of tree species," says Dr. Jiri Hulcr, a postdoctoral research associate at...

Plants, too, have an immune system that protects them against diseases. The early detection of pathogens and the subsequent immune response, in particular at the cell wall, work as a protective shield. However, the pathogens that cause plant diseases have their weapons, too. Some are able to suppress the natural cell wall reaction in plants. "One particularly ingenious attacker, powdery mildew, can even reprogram cells in such a way that they adapt their architecture and metabolism to...

San Francisco State University researcher finds bioluminescent fungus not seen since 1840In 1840, renowned English botanist George Gardner reported a strange sight from the streets of Vila de Natividade in Brazil: A group of boys playing with a glowing object that turned out to be a luminescent mushroom. They called it "flor-de-coco," and showed Gardner where it grew on decaying fronds at the base of a dwarf palm. Gardner sent the mushroom to the Kew Herbarium in England where it was...

Scientists have found that harmful fungal pathogens are enduring high temperatures, aggressive doses of detergents and rinsing salts, and both acid and alkaline types of water to take residency in dishwashers. The scientists took samples of the fungi in 189 homes in 101 cities on six continents. They said 56 percent of the dishwashers contained the black yeasts called Exophiala dermatitis along with its cousin fungus E. phaeomuriformis on the rubber seal on the appliance door. The study...

LMU chemists design a route for synthesis of loline alkaloids LMU chemists led by Professor Dirk Trauner have developed a concise and efficient method for the synthesis of the alkaloid loline and related compounds. Loline alkaloids are a biologically interesting group of natural products, which have unusual physicochemical and pharmacological characteristics, but are as of yet poorly understood. They are produced by fungal symbionts that infect weeds and forage grasses, and act as deterrents...

Scientists at Duke University Medical Center have found that larger fungal spores can be more lethal. Their findings about two different spore sizes of the fungus Mucor circinelloides, a pathogen that kills half or more of its victims, could help to develop new treatments and fight other types of fungal infections. Mucor infection is in the news as an environmental fungus contracted by people who had trauma in the wake of tornadoes in Joplin, Mo. Three out of eight patients had died by June...

Leafcutter ants are found in warmer regions of Central and South America. These remarkable social insects have evolved an advanced agricultural system. They feed on a specialized fungus that grows only in the underground chambers of the ants' nest. The ants actively cultivate their fungus, feeding it with freshly-cut vegetation and maintaining it free from pests and weeds. This is done by a symbiotic relationship with a colony of bacteria that grows on the ants that protect the fungus. The...
