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.

University of Delaware boasts six of the nation's best online graduate degree programs in latest U.S. News & World Report rankings

Six University of Delaware online graduate degree programs are ranked among the best in the nation by U.S. News & World Report in its 2026 U.S. News Best Online Programs, released Jan. 27, 2026. Both UD’s online master’s in education and online MBA ranked among the top 10% of their respective programs, at No. 25 and 26, respectively. Announced on Jan. 6, the online MBA program recently rose nine spots to No. 32 in the Poets&Quants 2026 Online MBA rankings. UD’s online master’s in nursing program ranked No. 35 out of 209 programs, rising 99 places over the past year. New for UD, the online master’s in educational/instructional media design program was recognized by peers at No. 11 in this education specialty ranking. UD’s online master’s in computer information technology program and online master’s in engineering ranked No. 64 in their respective areas. “These latest rankings recognize the expertise and dedication of our faculty and staff in delivering UD’s outstanding online graduate programs,” Interim Provost Bill Farquhar said. “We are committed to continually enhancing these programs and all the transformative opportunities that enable our students to meet their educational and career goals throughout their lives.” U.S. News selects several factors, known as ranking indicators, to assess each program in the categories outlined above. A program's score for each ranking indicator is calculated using data that the program reported to U.S. News in a statistical survey and from data collected in a separate peer assessment survey. This year’s edition evaluates more than 1,850 online bachelor’s and master’s degree programs using metrics specific to online learning. The rankings include only degree-granting programs offered primarily online by institutions with accreditation from recognized commissions. While the overall rankings methodology remains largely unchanged, U.S. News reported increased participation in this year’s data collection cycle, with more programs submitting statistical data and completing peer assessment surveys. According to U.S. News, this broader participation may reflect continued growth in online education nationwide. The University of Delaware offers over 35 online credit and non-degree professional programs. An online program from UD offers the same quality and rigor as an on-campus program and provides the flexibility to accommodate your busy schedule. UD is accredited by the Middle States Commission on Higher Education, and its online and on-campus degree programs have rigorous curricula delivered by experts, offer affordable program options, and provide students access to student support services, career fairs, recruiting opportunities and graduation ceremonies to celebrate student success. “UD's high-level rankings are in large part due to the positive outcomes that our students experience as a result of taking one of our online degrees or programs,” said Associate Provost for Online Learning and Innovation George Irvine. “Students tell us how much they enjoy learning from our accessible faculty and doing so in engaging and interactive online courses.” For more information about UD’s online degree programs, visit online.udel.edu. A complete listing of UD’s high-profile rankings is available on UD’s Institutional Research and Effectiveness Rankings webpage. Please note that the programs and specialties used in rankings may differ slightly from the names of UD’s degree programs.

How corporate competition can spur collaborative solutions to the world's problems

Why can’t large competitive companies come together to work on or solve environmental challenges, AI regulation, polarization or other huge problems the world is facing? They can, says the University of Delaware’s Wendy Smith. While it's difficult, the key is to have these companies collaborate under the guise of competition. Smith, a professor of management and an expert on these types of paradoxes, co-authored a recent three-year study of one of the most profound collaborations. Her team looked at the unlikely alliance of 13 competitive oil and gas companies that eventually formed Canada’s Oil Sands Innovation Alliance (COSIA), which works with experts worldwide to find innovative solutions for environmental and technical challenges in the region. Smith and her co-authors found that those companies were willing to collaborate, but only when collaboration was cast in the language, practices and goals of competition. Given the scope of our global problems, companies must continually work together to offer solutions. Creating that collaboration becomes critical, Smith said. This research offers important insight about how these collaborations are possible. Among the study's key findings: Competition can drive cooperation — if leaders harness it. It would make sense to assume that competition undermines collaboration. But the study finds that those who championed alliances used competitive dynamics to strengthen cooperation among rival firms. Rather than suppressing rivalry, leaders leveraged competition as a mechanism to enable joint action toward shared environmental goals. This reframes how organizations can manage tensions between competition and cooperation in partnerships. For example, COSIA leaders created competition between partners to see who would contribute the most valuable environmental innovations. Partners could only gain as much benefit from other company’s innovations commensurate with what they shared. A “Paradox Mindset” is key to complex collaborative success. The research identifies the importance of what the authors call a paradox mindset, which sees competition and cooperation not as opposites to be balanced but as interrelated forces that can be used in tandem. Leaders in the study who adopted this mindset were more thoughtful and creative about how to engage both competitive and collaborative practices in the same alliance. Traditional balance isn’t the goal — process over stability. Instead of pursuing a simplistic “balance” between competing and cooperating, the study shows that effective alliances evolve through process, where competition remains visible and even useful throughout the lifecycle of the alliance.
