Dr. Brian Langerhans discovers a new Gambusia (mosquitofish) with unusual morphology in Mexico.

Growers in North Carolina have begun to notice that wheat tends to be taller and to produce larger heads in response to sub-soil slits from previous crops, but whether the practice is really improving yields has been up for debate.
The research of Extension Crop Science Associate, Georgia Love's, tested vertical tillage -- systems which confine soil disturbance to soil movement chiefly upward and/or confined to the region for planting the next rows.
In Love's tests on $6/bushel wheat, the method added $15 per acre profit.
Other results and equipment types are discussed.

"Logu was recognized for his recent research on molecular microbial ecology of bacterial populations in mosquito habitats, microbe-insect interactions, and oviposition site attractants of mosquitoes, in collaboration with the Apperson and Schal labs. He helped develop a novel attract-and-kill management strategy for Aedes aegypti, using attractive bacteria in a sustained release formulation that attracts gravid females to lethal trap. He is also the principal investigator on an NIH R21 (exploratory) grant to identify bacterial factors that stimulate Aedes aegypti eggs to hatch."

Soybean growers in the Carolina’s and Virginia have more than two million acres of beans planted this year, much of the acreage in a late-planted, double-crop combination with wheat, barley, oats and a few other winter season crops.
“We do not recommend spraying soybeans with a fungicide to control Asian Soybean Rust if they are not yet blooming, if they are blooming, but rust has not been confirmed within 100 miles, or if full sized seeds are present in the top of the plant (stage R6),” says North Carolina State University Soybean Specialist Jim Dunphy.

"Is Norovirus, a food borne pathogen? with Lee-Ann Jaykus, Ph.D., Professor, Food Science, College of Agriculture & Life Sciences, NCState University, Raleigh, NC"
In this YouTube audio interview on the AME Food Testing Show (about 38 minutes long), Dr. Jaykus explains the research goals of her team, funded by a $25 million USDA grant -- USDA's largest ever for food safety.
Dr. Jaykus leads the USDA-National Institute of Food and Agriculture Food Virology Collaborative, which consists of more than 30 collaborators from academia, industry and government who will focus on enhanced understanding, surveillance and control of food-borne human noroviruses, with the ultimate goal of reducing the burden of food-borne disease and the human suffering it causes.
Dr. Jaykus explains that Norovirus biology differs from that of bacteria, presenting unique challenges in detection, deactivation, and infection prevention.

A new paper in the Proceedings of the National Academy of Sciences shows that the epistatic network in fruit flies can be used to predict variation in quantitative genetic traits -- those controlled by multiple genes.
A team of researchers at NC State University published the paper, for which Dr. Trudy Mackay, Wm. Neal Reynolds and Distinguished University Professor of Genetics, is the corresponding author.
The paper bolsters the effort to predict how genes affect physical or behavioral traits through the genotype-phenotype map. Understanding how genes interact in the process known as epistasis would move the effort closer to the goal.
The effects of these gene-gene interactions ... are difficult to gauge in human populations because some variations are unknown, says Dr. Trudy Mackay.

"New research led by researchers at North Carolina State University shows that exposure to the chemical bisphenol A (BPA) early in life results in high levels of anxiety by causing significant gene expression changes in a specific region of the brain called the amygdala. The researchers also found that a soy-rich diet can mitigate these effects.
“We knew that BPA could cause anxiety in a variety of species, and wanted to begin to understand why and how that happens,” says Dr. Heather Patisaul, Associate Professor of Biology at NC State and lead author of a paper describing the work. BPA is a chemical used in a wide variety of polycarbonate plastics and epoxy resins, and is used in consumer products such as some food containers."
Based on last year’s success and the ongoing high prices for soybeans for double-cropping, North Carolina growers are expected to plant another record crop of wheat this fall.
On Sept. 17, CALS weed scientist & researcher, Dr. Wes Everman, will discuss the most recent research-based wheat weed control methods, chemicals & recommendations.

Scientists have assumed that elevated CO2 would stimulate the beneficial plant root fungi, arbuscular mycorrhizae (AMF), to sequester carbon in the soil.
This study challenges that assumption, and predictions based upon it, of carbon balance in future climate change. USDA funded the study.
Drs. H. David Shew (Plant Pathology) & Thomas Rufty (Crop Science) co-authored with Drs. Fitz Booker & Kent Burkey, of CALS & the USDA Agriculture Research Service. The first author is former NC State graduate student, Lei Cheng; and postdoctoral researchers Cong Tu & Lishi Zhou also co-authored.

The new cases are part of a national epidemic that’s on pace to be the worst in the 13-year history of the disease in the United States.
CALS Public Health Entomologist, Dr. Michael Reiskind, comments on the ecology of the disease and the difficulty of predicting outbreaks.
Through dynamic research, education and outreach programs, North Carolina Sea Grant links university researchers to the people, businesses and governments that manage, use and enjoy coastal and marine resources.
"Ecologist Susan N. White, currently director of the Hollings Marine Laboratory in Charleston, S.C., will be the new executive director for North Carolina Sea Grant and the Water Resources Research Institute of the University of North Carolina upon the retirement of Michael P. Voiland in December.
"Susan brings a strong science background, as well as leadership working with a mix of partners and stakeholders," notes Vice Chancellor Terri L. Lomax of North Carolina State University, where the two state/federal partnership programs are headquartered.
"She will be a great leader for Sea Grant and WRRI programs here that have strong traditions of assisting and guiding communities, businesses, organizations and the public," Lomax adds. Sea Grant focuses on the ecosystems and economies of the coastal region, while WRRI supports research and training related to freshwater topics statewide."
