Sex Life of Killer Fungus Finally Revealed

piggy submitted, created time 13 hours 7 minutes (www.sciencedaily.com)

Biologists at The University of Nottingham and University College Dublin have announced a major breakthrough in our understanding of the sex life of a microscopic fungus which is a major cause of death in immune deficient patients and also a cause of severe asthma.

The discovery of a sexual cycle in the fungal pathogen Aspergillus fumigatus is highly significant in understanding the biology and evolution of the species and will shed new light on its ability to adapt to new environments and its resistance to antifungal drugs

Fungi break acceleration record to escape dung

sea-maid submitted, created time 2 months 2 weeks (environment.newscientist.com)

In order for dung-dwelling fungi to survive, their spores must be ingested by some grazing animal. However dimwitted cows may seem, however, they do know not to eat grass that's right next to their own dung. Scientists have long known that fungi were able to shotput their spores as much as 2.5 meters away. What they didn't know until now is that they set the acceleration record for living cells.

Fungi can propel spores at 180,000 g. This beats the runner-up, jellyfish stingers (40,000 g) by more than a facter of four.

Benefits of "magic mushroom" therapy are long lasting

sea-maid submitted, created time 4 months 3 weeks (www.nature.com)

The benefits for people who have had positive or even mystical experiences induced by the psychedelic drug psilocybin — the psychoactive ingredient in "magic mushrooms" — linger for as much as a year, according to the latest follow-up study of such patients.

The study offers more support to those who argue that, when used responsibly, some drugs more commonly taken for leisure can safely be used to relieve the stress associated with severe chronic diseases such as cancer.

Fungi can stabilize uranium pollutants!

U.S. military equipment uses depleted uranium. Its density makes it very useful for armor and munitions. However, even though it is less radioactive than regular uranium, the tiny particles that are released on contact can still leave soil and water supplies dangeously polluted. Researchers have foudn a naturally occuring mycorrhizal fungus that can convert uranium particles into a stable form that will not enter the food chain.

AVR2, a fungal effector protein targets diversifying defense-related cys proteases of tomato

kavin submitted, created time 6 months 3 weeks (www.ncbi.nlm.nih.gov)

In this paper, secretion of protease inhibitor AVR2 by C. fulvum during infection suggests that tomato papain-like cysteine proteases (PLCPs) are part of the tomato defense response. They show that the tomato apoplast contains a remarkable diversity of PLCP activities with seven PLCPs that fall into four different subfamilies.

Fungi, a Possible Answer to the Origin of Sex Chromosomes

Sue Wu submitted, created time 8 months 1 week (www.sciencedaily.com)

Fungi do not have sexes, just so-called mating types. A new study shows that there are great similarities between the parts of DNA that determine the sex of plants and animals and the parts of DNA that determine mating types in certain fungi.

New Enzyme founded to provide transgenic resistance to FHB

Sue Wu submitted, created time 10 months 2 weeks (www.jbc.org)

Fusarium head blight (FHB) is a serious plant disease caused by fungal species belonging to the genus Fusarium. Shown here is the structure of trichothecene 3-O-acetyltransferase from F. graminearum complexed with deoxynivalenol superimposed onto an infected wheat head. This enzyme has promise for providing transgenic resistance to FHB.

Hungry fungi chomp on radiation

enderyin submitted, created time 1 year 6 months (www.nature.com)

From plastic to asbestos, cardboard to jet fuel, fungi will eat just about anything. Now researchers have found another dish in the fungal diet: radiation. Not radioactive compounds, which have long been known to be on the menu — radiation itself! Ekaterina Dadachova and her colleagues at the Albert Einstein College of Medicine in New York have discovered that some fungi can use a molecule called melanin, a pigment also found in human skin, to harvest the energy from radiation and use it for growth

Einstein researchers' discover 'radiation-eating' fungi

alpha submitted, created time 1 year 6 months (www.biologynews.net)

"Scientists have long assumed that fungi exist mainly to decompose matter into chemicals that other organisms can then use. But researchers at the Albert Einstein College of Medicine of Yeshiva University have found evidence that fungi possess a previously undiscovered talent with profound implications: the ability to use radioactivity as an energy source for making food and spurring their growth."
