A unique method for delivering compounds that could positively impact the global battle against HIV and AIDS may be possible, thanks to researchers in Penn State's College of Agricultural Sciences.
A parasitic fungus that reproduces by manipulating the behavior of ants emits a cocktail of behavior-controlling chemicals when encountering the brain of its natural target host but not when infecting other ant species, a new study shows. The findings, which suggest that the fungus "knows" its preferred host, provide new insights into the molecular mechanisms underlying this phenomenon, according to researchers.
A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit its 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.
By spotting, collecting and submitting suspected Asian longhorned beetles to experts, Pennsylvanians can help keep the non-native, invasive wood-boring threat to the state’s trees at bay, according to agriculture officials.
Laser-guided robots and computer-programmed cleaning devices are allowing dairy farmers to work smarter rather than harder.
Trait can make mosquitos resistant to the malaria parasite.

The Office of Research and Graduate Education supported a two-day leadership workshop for Post-Docs this summer.
The feature story in this month's issue of CSA news focuses on the signature food systems project of the Northeast Regional Center for Rural Development.
Mosquitoes infected with the bacteria Wolbachia are more likely to become infected with West Nile virus and more likely to transmit the virus to humans, according to a team of researchers.
If you catch a smallmouth bass in the Susquehanna or its tributaries, with a wire trailing from its underside, it is a participant in a study of fish movement related to wider research into the causes of fish diseases in the river system.
Fine-scale climate model projections suggest the possibility that population centers in cool, highland regions of East Africa could be more vulnerable to malaria than previously thought, while population centers in hot, lowland areas could be less vulnerable, according to a team of researchers. The team applied a statistical technique to conventional, coarse-scale climate models to better predict malaria dynamics at local levels.
An international team of researchers has discovered honey bee colonies in Newfoundland, Canada, that are free of the invasive parasites that affect honey bees elsewhere in the world. The populations offer a unique opportunity to investigate honey bee health, both with and without interfering interactions from parasites.
Malaria parasites alter the chemical odor signal of their hosts to attract mosquitos and better spread their offspring, according to researchers, who believe this scent change could be used as a diagnostic tool.
Cocoa farmers this year will lose an estimated 30 to 40 percent of their crop to pests and disease, and concern is growing about sustainability in cocoa production. Scientists at Penn State's Huck Institutes of the Life Sciences have found – in a safe, biodegradable compound – a potential alternative to the hazardous antifungal agents currently being used to combat one of the most damaging cacao diseases, Phytophthora pod rot (also known as Black Pod).
Penn State's equine science team uses microchips, social media and live-streaming video technologies throughout the life cycle of the University's horses and during the department’s various events.
Contrary to recent well-publicized research, habitat loss, not insecticide use, continues to be the best explanation for the declines in grassland bird populations in the U.S. since the 1980s, according to a new study by ecologists.
With recent headlines about dangerous "superbugs," an outbreak of Salmonella from chicken parts on the West Coast and the announcement by a national restaurant chain that it plans to serve only "antibiotic-free" chicken, it's no wonder the public is alarmed and confused.
Female mice deprived of dietary zinc for a relatively short time before conception experienced fertility and pregnancy problems and had smaller, less-developed fetuses than mice that ingested zinc during the same times, according to researchers in Penn State's College of Agricultural Sciences.
