Scientists believe that the organisms were able to thrive during this period because the world's forests had been wiped out. This would explain how the organisms, which are known as Reduviasporonites, were able to proliferate across the planet.

Fungal spores can effectively infect and kill malaria mosquitoes, even those that are resistant to pesticides. Moreover, the mosquitoes become more susceptible to the pesticides as the fungal infection increases.

But a recent analysis of frog surveys done at eight Central American sites shows the situation is worse than thought. Under pressure from an invasive fungus, the frogs in this biodiversity hot spot are undergoing "a vast homogenization." "We're witnessing the McDonaldization of the frog communities," comments the lead author of the new study.

Until now, most researchers thought that no budding yeasts possess the RNAi pathway because Saccharomyces cerevisiae, the protoypical model budding yeast does not. Some budding yeasts cause human diseases, while other budding yeasts are used in research as models for more complicated organisms, in industry to create beer and biofuels, and in pharmaceuticals to produce drugs and vaccines.

Using mutant forms of the C. albicans yeast which lacked different parts of the yeast cell wall, researchers have uncovered a three-pronged mechanism by which the body's immune defenses attack the invading fungus.

Results show that bacteria, fungi and parasites, unlike viruses, appear to have allowed the introduction of mutations in the genes of some proteins of the innate immunity system, thus enabling greater genetic variability. In some cases, these mutations may even constitute an advantage, giving the human host improved resistance to infectious diseases such as leprosy or tuberculosis.

Because of their changeability and huge numbers, they are able to overwhelm the defence mechanisms of both plants and animals. The use of chemicals is usually the only remedy but this is also undesirable. Will future research offer a sustainable means of combating these blights and preventing failed harvests?

Phallus drewesii belongs to a group of mushrooms known as stinkhorns which give off a foul, rotting meat odor. There are 28 other species of Phallus fungi worldwide, but this particular species is notable for its small size, white net-like stem, and brown spore-covered head. It is also the only Phallus species to curve downward instead of upward.
