Those flying spiders are harmless; don't tell that to arachnophobes

A breed of flying arachnids known as Joro spiders are headed to the northeast this summer, specifically Pennsylvania, New Jersey and Delaware. Experts say there's nothing to fear, but that doesn't make them any less scary to those who have an issue with the eight-legged bug eaters.


Two University of Delaware experts can provide insight and (some) comfort regarding any potential risk to humans.


Brian Kunkel, an expert in landscape and household insects and entomology for ornamentals with UD's Cooperative Extension, confirmed the yellow and black spider will be making its arrival in the Tri-State area but said it isn't likely to be noticed until the fall, when it grows to visible size. Regardless, there is no need to be concerned. In the unlikely event that it bites, you would feel something akin to a bee sting, Kunkel said.


Doug Tallamy, professor of entomology and wildlife ecology, confirmed the spiders are on the way but echoed Kunkel's assessment that there is nothing to be worried about.

Beneath the bed: The psychology behind America's fascination with monsters and why we love being scared

Have you ever wondered why we just can't get enough of the creatures hiding beneath our beds and lurking in the shadows? Whether it's watching a spine-tingling horror movie or telling ghost stories around the campfire, Americans have a long-standing love affair with all things spooky and scary. But what's driving this fascination? Persephone Braham is a Professor of Spanish & Latin American Studies at the University of Delaware and has those answers.  She can talk about monsters in a variety of ways including the following: Monsters are therapeutic. They act out our fears – and our fantasies. We love to hate monsters. They channel our anxieties and expose our desires. Monsters sneak into our dreams, stalk us in the dark and make us scream. Why do we love them? Have you hugged a monster today? Why do we need monsters? They keep us from crossing the line. Who believes in monsters? Anyone who considers themselves human. What are monsters, and why do we need them? From ghosts to vampires, every culture has its favorite monsters. Halloween scream: Why we like to play vampires. Who decides what a monster is? You do! Why do zombies want your brains? Monsters and eerie tales serve as representations of our internal anxieties and societal fears. They act as metaphors for the complex emotions and situations we encounter. Braham can give this context and more. She can be contacted by emailing mediarelations@udel.edu.

New path to combating global malnutrition found in soil

A new University of Delaware study has found that a naturally occurring soil microbe can boost protein-building amino acids in wheat. The finding by UD's Harsh Bais and others could pave the way for nutrient-rich staple crops — helping combat global malnutrition as fluctuations in weather reduce crop quality. In the study, published in the journal Frontiers in Microbiology, Bais and a team of researchers from UD, Stroud Water Research Center and the Rodale Institute investigated how a bacteria naturally found in the soil that is beneficial to human health can enhance the levels of the amino acid and antioxidant ergothioneine in spring wheat.  The researchers grew the spring wheat — one of the most widely consumed cereal crops — in a laboratory. After letting the seeds germinate and grow for seven days, they added a strain of bacteria called Streptomyces coelicolor M145 to the spring wheat roots. After combining the bacteria and the plant, they separated the plant’s leaves and roots. Then, they extracted the amino acid ergothioneine from the samples, working to determine how much protein was in the plant’s roots and shoots. They found that 10 days after S. coelicolor had been added to the spring wheat roots, the bacteria was able to inhabit spring wheat’s roots and shoots, producing ergothioneine, bypassing the plant’s innate defense mechanisms, and fortifying the spring wheat. Wheat roots were inoculated with the benign bacteria Streptomyces coelicolor. The image shows the presence of bacteria on the root hairs on day 5. “It’s unusual," Bais said. “Unless there is a mutual advantage for either the plant or the microbe.” The findings suggest that an alternative plant breeding approach could be utilized to associate plants with benign microbes to increase protein content in staple crops. All of our cereal crops are very low in protein. Think rice and breakfast cereals, common foods people eat, derived from these crops. “This approach of harnessing a natural association of microbes with plants may facilitate fortifying our staple crops, enhancing global nutritional security,” Bais said. Bais said he believes using microbes to transport nutrients depends on the microbes’ relationship with plants’ roots. He continues to work to catalyze the colonization of plant roots by beneficial microbes. "Establishing a partnership with the appropriate types of microbes or microbial consortia for plants represents a method of engineering the rhizosphere — the region of the soil near plant roots — to foster a more favorable environment for either microbial associations that stimulate plant growth traits or enhance nutrient availability, which is the path forward,” Bais said. Bais, a professor of plant biology who was named a UD Innovation Ambassador earlier this year, said plants’ “below-ground” traits, such as how nutrient-dense they are, have long been overlooked. “As far as food security, we will have significant challenges by 2050 when the world’s population doubles,” Bais said. “We incentivize our farmers for crop yield; we don’t incentivize them for growing nutrient-dense crops. Growing nutrient-dense plants will enable the population to be fed better and avoid any potential nutrient deficiencies.” The study was funded by the U.S. Department of Agriculture and the Foundation for Food and Agriculture Research. Scientists have become more interested in soil bacteria as a means to solve issues with malnutrition and nutrient deficiencies. Alex Pipinos, the lead author and a UD Class of 2025 graduate with a master’s in microbiology, said environmental conditions are one factor diminishing protein content in plants. “Essentially, crops are becoming less nutrient-dense,” Pipinos said. “The more nutrients in crops, the more healthy humans can be.” Pipinos points to a strong link between soil microbes, plant health and human health. Ergothioneine, she said, has already been shown to lower the risk of cardiovascular disease. It’s also been shown to combat cognitive decline, with a strong link to healthy cognitive aging. “By enhancing ergothioneine in plants, we can improve human health,” Pipinos said.

From field to festival: How pumpkins grew into an autumn symbol

Type “Halloween” into your phone’s emoji search bar, and you’ll get three icons: a skull, a ghost, and a jack-o'-lantern. The skull and ghost make sense — but how did the pumpkin carve out such a starring role in our fall celebrations? Cindy Ott, associate professor of history and material culture at the University of Delaware, has the answer. She literally wrote the book on pumpkins, exploring how this humble orange gourd grew from a survival crop to a powerful symbol of American identity and nostalgia. Today, pumpkins dominate the fall season — from pumpkin pies and soups to the ever-popular pumpkin spice latte. Ott’s research uncovers how the pumpkin’s transformation from practical produce to cultural icon reflects broader shifts in American history, values, and traditions. To schedule an interview with Professor Ott, contact MediaRelations@udel.edu.
