A microplitis demolitor wasp parasitizes a soybean looper caterpillar by injecting eggs and bracovirus. Braconid wasps use a class of viruses called bracoviruses that can hijack the cells of their hosts without destroying them, expressing genes important to the survival and development wasp’s offspring while they feed on the live host.

Viral Protection 01/27/25 Maria M. Lameiras
Supported by a $1.1 million award from the National Science Foundation, University of Georgia entomologists Gaelen Burke and Michael Strand are seeking answers about how parasitic wasp biology has developed to use viruses passed down from parent to offspring to ensure survival. Scientists have been able to trace the relationship between the wasps and their viruses back 100 million years. Today about 55,000 types of wasps carry these types of inherited viruses.
January is Radon Action Month CAES News
Radon Action Month 01/24/25 Rebecca Cantrell
Radon Action Month, observed every January, is a reminder to protect your home and family from the dangers of radon exposure. Radon is a colorless, odorless, and tasteless radioactive gas that forms naturally from the breakdown of uranium in soil, rock, and water. It can seep into homes through cracks in foundations, construction joints, and other openings, building up to dangerous levels indoors. Prolonged exposure to high levels of radon is the second-leading cause of lung cancer in the U.S., surpassed only by smoking.
Colby Ruiz CAES News
A Doctor's Journey 01/23/25 Aaron Hale
Dr. Colby Ruiz was a teenager when he watched his first surgery. He volunteered in the operating room at Valdosta’s South Georgia Medical Center, where his parents worked as nurses. Ruiz could have ended up in any of the hospital units except, at 14, he really didn’t want to wear the pink “candy striper” uniform of most hospital volunteers. When Ruiz learned that OR volunteers wore green, he was all in.

For Spacious Skies 01/22/25 Aaron Hale
Compared to some of the long, more strenuous hikes at Yosemite National Park in California, the venture up the granite outcrop at Olmsted Point is short if a little steep. But an epic view awaits the 18 University of Georgia students who make the climb. High above Yosemite Valley, they gaze westward to make out Half Dome in the distance. Other peaks of various shapes and features stretch on endlessly. Class is now in session.
Palisades Fire from Playa Vista, Los Angeles CAES News
Prescribed burns 01/21/25 Maria M. Lameiras
As shocking images of the fire-blasted hills around Los Angeles demonstrate, wildfires have become an increasing concern in the United States, particularly in regions where suppression strategies have dominated for decades. A new study by University of Georgia researcher Yukiko Hashida examines how prescribed burns could play a key role in mitigating wildfire risks.

Branch Honored 01/17/25 Brandon Ward
William “Bill” D. Branch, Georgia Seed Development Professor in Peanut Breeding and Genetics in the College of Agricultural and Environmental Sciences, has been elected as Fellow for the National Academy of Inventors (NAI). Branch is the 17th UGA faculty member to receive this honor, which recognizes inventors whose innovations have had a significant impact on society, economic development and quality of life.

Animal Magnetism 01/15/25 Sameeka Prabath Rajamani
In Associate Professor Kari Turner’s “Companion Animal Care” class, Penelope stands in front of the lecture hall, her large, brown eyes taking in her audience. Penelope, a piebald pit bull terrier mix, and her caretaker, Katlyn Davis, a fourth-year animal biosciences major, are there to tell their rescue story. Three years ago, the months-old pup was found abandoned, malnourished and covered in mange under an abandoned house.

Cyst Nematodes 01/14/25 Gary Goettling
People love the taste of sugar beets’ primary byproduct: white sugar. Soilborne cyst nematodes — parasitic, microscopic worms — enjoy the root vegetable, too, but as their sole food source. It’s an obstinate, expensive problem for farmers that researchers at the University of Georgia’s College of Agricultural and Environmental Sciences are working to solve.

Organic Shelf Life 01/10/25 Lillian Sosbee
Organic fruits and vegetables often face a higher risk of spoiling and harboring foodborne pathogens than their conventional farming counterparts. Because organic growers and packers must adhere to higher production standards and restrictions on chemical additives, University of Georgia experts are exploring alternative methods for protecting organic products and consumers through a new $3.5 million grant from the United States Department of Agriculture.
Peanut Innovation Lab Director Dave Hoisington works with Rachelle Djiboune at CERAAS, where Djiboune is characterizing groundnut seed as high-oleic or not. The handheld NIR device validated by Hoisington has made her work many times faster. CAES News
High oleic testing 01/10/25 Allison Floyd
Wouldn’t it be nice if you could look inside a peanut kernel and see the nutritional content hiding there? It’s possible. A device calibrated and deployed by the Peanut Innovation Lab is allowing partners to test peanut seed where they are – avoiding time-consuming and expensive off-site lab tests – to see which plants have the desired oil content. The technology is saving money and speeding up the process to develop new high-oleic lines where people need them the most.
