David Hughes understands the devastating effects a plant disease can have on crops and the people who rely on them for food and income. This understanding, and the mentoring he received early in his research career, germinated the seed of an idea that has borne fruit in the form of an online network designed to get practical knowledge about plants and plant diseases into the hands -- and mobile devices -- of farmers around the globe
Change in disturbance regimes -- rather than a change in climate -- is largely responsible for altering the composition of Eastern forests, according to a researcher in Penn State's College of Agricultural Sciences.
Siela Maximova, senior scientist and professor of horticulture in the College of Agricultural Sciences, will speak Oct. 16 at a side event at the 2014 Borlaug Dialogue in Des Moines, Iowa, the annual symposium at which the World Food Prize is awarded.
How people perceive and taste alcohol depends on genetic factors, and that influences whether they "like" and consume alcoholic beverages, according to researchers in Penn State's College of Agricultural Sciences.
Monnat receives $100K grant from Robert Wood Johnson Foundation
An international team of researchers has designed decoys that mimic female emerald ash borer beetles and successfully entice male emerald ash borers to land on them in an attempt to mate, only to be electrocuted and killed by high-voltage current.
The taste of common sugar substitutes is often described as being much more intense than sugar, but participants in a recent study indicated that these non-nutritive sugar substitutes are no sweeter than the real thing, according to Penn State food scientists.
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.
Congratulations to Kerry Belton, Stephanie Bora, Bastian Minkenberg, Michael Podolsky, Girish Kirimanjeswara.
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.
