GAINESVILLE, Fla. — A University of Florida researcher is exploring whether the latest plant, animal or human health threats will come from the sky.

Using the first ever high-altitude sampling device designed to collect microorganisms from the upper atmosphere, Andrew Schuerger, an aerobiologist with UF’s Institute of Food and Agricultural Sciences, will examine the massive dust clouds that roll into Florida from Africa each year.

The maiden flight of the device, known as Dust at Altitude Recovery Technology or DART, was flown on an F-104 Starfighter jet Tuesday at the Kennedy Space Center in Cape Canaveral.

GAINESVILLE, Fla. — A multistate beef cattle Extension team that includes Cliff Lamb of the University of Florida’s Institute of Food and Agricultural Sciences has garnered a national award for its efforts to help ranchers boost calving rates and strengthen U.S. beef production.

This week, the Beef Reproduction Task Force was named one of five programs chosen to receive a 2013 NIFA Partnership Award from the U.S. Department of Agriculture’s National Institute of Food and Agriculture. The award was formally presented at the Association of Public and Land-grant Universities annual meeting Nov. 10-12 in Washington, D.C.

Jack Payne, UF senior vice president for agriculture and natural resources, called the award a “well-deserved milestone” for the task force, which was launched in 1999 to help Extension personnel educate ranchers about the latest reproductive technologies and explain how those technologies might benefit their operations.

“Beef cattle production is a key agricultural industry for Florida and high calving rates are key to ranchers’ success,” Payne said. “We could not be more pleased that Dr. Lamb and his colleagues are being honored for their efforts to help ranchers succeed with one of the pivotal economic issues they face.”

GAINESVILLE, Fla. – More than half of all fresh produce in the United States is wasted every year, the vast majority due to retailers and consumers throwing out fruits and vegetables gone bad after being at the store or home for too long.

Jeffrey Brecht is the leader of one of two research groups at UF awarded grant money by the National Strawberry Sustainability Initiative.

GAINESVILLE, Fla. – The University of Florida has released three smart device apps of interest to those in the irrigation business, and for the time being, users can download them for free.

The first three apps to be released were designed for citrus, strawberry and urban turfgrass irrigators, said Kati Migliaccio, an associate professor in agricultural and biological engineering, based at the UF Institute of Food and Agricultural Sciences’ Tropical Research and Education Center in Homestead, Fla.

Florida weather network adds three stations

GAINESVILLE — The Florida Automated Weather Network is bigger than ever, with three new sites added this year.

Stations added since April are in Citrus, Okeechobee and Palm Beach counties, said Rick Lusher, manager of the network at the University of Florida’s Institute of Food and Agricultural Sciences.

That makes 41 stations now in the network, built in 1998 to give the state’s agricultural producers the most current weather information possible.

GAINESVILLE, Fla. — University of Florida researchers have some encouraging results in the battle against citrus greening.

They have identified citrus cultivars, in this case 16 citrus rootstocks, most of which show a lower rate of infection and more tolerance to citrus greening – the dreaded disease that has wreaked havoc through Florida’s citrus industry since its arrival in the state in 2005.

GAINESVILLE, Fla. — Many scientists see great promise in algae as a new source of oil — a sustainable, environmentally sound way to break the world’s fossil fuel dependence.

Algal lipids from microalgae are one of the best sources for biofuels – algae grow quickly, tolerate extreme weather conditions, and do not pose the same issues as biofuel crops that are grown both for fuel and food.

Many research teams in academia and private industry are struggling, however, with one vexing problem with algae as a fuel source: The conditions that promote algal growth aren’t the same as the conditions that allow the algae to create the maximum amount of oil.

UF/IFAS study finds light can change flavor, scent volatiles in plants and fruits

Topic(s): New Technology, Research

GAINESVILLE, Fla. — There’s an old head-scratcher that asks whether the refrigerator light really goes out when you close the door.

The answer may be about to change.

Scientists have known for hundreds of years that plants respond to light in a variety of ways.

But the results of a new University of Florida study tell them how specific light wavelengths can manipulate volatile compounds that control aroma and taste in several high-value crops, including petunia, tomato, strawberry and blueberry.

GAINESVILLE, Fla. – Two papers co-authored by a University of Florida professor have been highlighted by a leading science journal.

The science journal Plant Physiology recently named the studies “Crop Genome Plasticity and Its Relevance to Food and Feed Safety of Genetically Engineered Breeding Stacks” and “Evaluating the Potential for Adverse Interactions within Genetically Engineered Breeding Stacks” as Editor’s Choice papers.

The papers were co-authored by Curtis Hannah, an professor with the horticultural sciences department, part of the UF Institute of Food and Agricultural Sciences.

GAINESVILLE, Fla. — University of Florida researchers have found, for the first time, that crop models predicting yields for one of the world’s most important crops begin to disagree under climate change scenarios.

By knowing where those models break down, researchers will be better able to improve them. The computerized models predict crop yields for wheat, one of the world’s most-consumed foods.

Scientists use crop models to foresee which parts of the world may face the greatest food shortages, so that efforts to improve food production can be directed to those places.
