Since first making an appearance in Georgia in 2014, Joro spiders have steadily expanded their range in Georgia, and now — just in time for Halloween — the spooky-looking species has reached the University of Georgia Research and Education Garden on the UGA Griffin campus.

A multidisciplinary team of researchers at the University of Georgia and two partner institutions have been awarded a $15.8 million grant over five years from the U.S. Department of Energy to reengineer poplar trees to be used as a sustainable energy source. The researchers will use biotechnology approaches to breed the trees as a multipurpose crop that can be used for bioenergy, biomaterial and bioproduct alternatives to petroleum-based materials.

They have been described as palm-sized, parachuting creatures with the potential to spread up the East Coast. Now dozens of webs are appearing in trees, on fences and in gardens around the Southeast, and social media and message boards are buzzing with Joro spider sightings. Discussions of eradication methods ranging from chemical sprays to “Joro sticks” are rampant. Joro season is here.

Halfway through 2022, Earth is on course for another top-10 finish in global temperature. After six months, the National Oceanic and Atmospheric Administration (NOAA) reported that the period from January through June 2022 was the planet’s sixth warmest on record, with observations that go back to 1880. Antarctica also saw its lowest June ice coverage on record.

The common bean — which includes many varieties of dry beans, from navy and black beans to red, pinto and green beans — are an important nutritional source for many world populations. However, rapidly changing climate conditions are making them increasingly difficult to grow in many locations due to high temperatures and susceptibility to diseases and pests.

Many studies have shown that prenatal stress in mothers can be linked to adverse outcomes in the physical, emotional, cognitive and behavioral well-being of children. Now a study at the University of Georgia is examining how pre-hatch exposure to the stress-associated hormone corticosterone influences immune function in baby bluebirds.

As climate variability increasingly affects producers across the Southeastern U.S., Wes Porter spends a lot of time thinking about water — specifically, crop irrigation — and how available tools can benefit farmers threefold.

Using fertilizer to increase crop yields in sub-Saharan Africa may seem like a logical choice, but farmers in rain-fed areas must also weigh the potential for low rainfall or excess heat during the growing season.

The citizens of South Carolina will be joining the Great Georgia Pollinator Census for the August 2022 count, expanding the reach of the pioneering project in the Southeast. University of Georgia Cooperative Extension launched the Great Georgia Pollinator Census in 2019 as a citizen science research project inviting Georgians from across the state to document pollinator populations.
