Parasitic Fungus Manipulate Hosts To Die On The 'Doorstep' Of The Colony

By Chuck Gill, Penn State A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit their infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential new hosts, according to researchers at Penn State and colleagues at Brazil's Federal University of Vicosa. Previous research shows that Ophiocordyceps camponoti-rufipedis, known as the "zombie ant fungus," controls the behavior of carpenter ant workers...

Stigmatization may have once served to protect early humans from infectious diseases, but that strategy may do more harm than good for modern humans, according to Penn State researchers. "The things that made stigmas a more functional strategy thousands of years ago rarely exist," said Rachel Smith, associate professor of communication arts and sciences and human development and family studies. "Now, it won't promote positive health behavior and, in many cases, it could actually make the...

A parasite that fights the zombie-ant fungus has yielded some of its secrets to an international research team led by David Hughes of Penn State University. The research reveals, for the first time, how an entire ant colony is able to survive infestations by the zombie-ant fungus, which invades an ant's brain and causes it to march to its death at a mass grave near the ant colony, where the fungus spores erupt out of the ant's head. "In a case where biology is stranger than fiction, the...

Richard Dawkins' Extended Phenotype (EP) concept is as relevant now as when it was first proposed 26 years ago and is not at odds with other evolutionary explanations. This was the conclusion of a recent workshop on the Extended Phenotype today, organized by the European Science Foundation (ESF). The EP states that the genes of an organism can be expressed beyond its immediate biological boundary, extending for example to birds' nests, or the behavior of hosts infected by parasites. The key...

By Paul Snyder In recent years, residents across the state balked at proposals to build wind farms where they live. In Columbia County that's not the case -- yet. "The landowners I've talked to are pretty much in favor of it," said Randolph Town Chairman David Hughes. "I'm hoping it works, but, of course, I have to look after the people of the town, too." If opposition remains light in the towns of Randolph and Scott in Columbia County, it could be easy sailing for We Energies' Randolph...
