Concepts and habits from gasoline refueling found to mislead EV charging

Many electric vehicle (EV) drivers carry over concepts and habits acquired from driving gasoline cars when they are charging of EVs – but the mismatch leads to time wasted, inconvenience and “range anxiety” about not finding a charger when needed, according to a new study published in the journal Energy.


The research was carried out by Professors Willett Kempton of the University of Delaware and Frances Sprei of Chalmers University in Sweden, both experts in EV technology and usage.


They interviewed EV users in both Sweden and the United States, finding unanticipated and previously unreported concepts and habits of EV charging.


Among the other findings:


  • If industry and consumers take advantage of these findings, that could lead to more effective charging methods, help new EV buyers adapt, and inform planning of charging stations.


  • Novice EV drivers, and even many of those who had months of EV experience, monitor the battery charge gauge while driving, then when the gauge is low, seek a charging station to recharge. This “monitor gauge” model is derived from driving gasoline-powered vehicles.


  • By contrast, the study found that a few experienced EV drivers had developed a strategy of selecting a trigger event, and using it to spur them to plug in their EV.


“Some of the more sophisticated EV users had picked a repeating event that happens at a place they can plug in and at a time or event lasting several hours. This is common when returning home at the end of the day or arriving at work," Kempton said. “A few people had selected unexpected triggers, such as shopping, and for one, when walking his dog in the evening.”

From spacesuits to style icons: University of Delaware fashion grads make their mark on the industry

One of the best measures of a college program is where their alums land after graduation and beyond. In addition to the impressive list of soon-to-be degree holders who have already landed excellent jobs, the University of Delaware's fashion and apparel studies program can boast a roster of alums who now have prominent positions with some of the industry's most iconic companies as well as major retailers. Faculty at UD can talk about the materials that make up the proverbial fabric of their hidden gem of a program on the campus in Newark, Delaware. A quick snapshot of what some of the alums are up to: • Two students who have developed materials for space programs, including one who developed spacesuit textiles for future lunar missions. • A fashion merchandising graduate degree holder who now is a point person for sustainability at Tapestry, the home of iconic brands like Coach and Kate Spade. • High ranking executive at Target Brands. • An alum with a resume that includes Ralph Lauren and now Steve Madden. • Textile assistant with The Kasper Group, whose portfolio includes Nine West, Anne Klein, Kasper, Le Suit and Jones New York. Among this year's graduates is a star field hockey player from Argentina who landed a job at fashion retailer Moda Operandi; an award-winning student who will continue her pursuit of "changing the world" and making the fashion industry more sustainable as a graduate student at UD; and an entrepreneurship minor who paired her experience playing volleyball with design research that resulted in more comfortable apparel for athletes. To speak to one of these past or future graduates, contact mediarelations@udel.edu. Faculty from the program are also available for interviews: Huantian Cao, professor and department chair; Sheng Lu, professor and graduate director; and Brenda Shaffer, associate chair and undergraduate director.

Education expert: Delaware needs to reform its education funding system

In the next year, residents of Delaware will have the opportunity to voice their opinions about school funding in support of the students and teachers in the state's public schools. School funding reform is urgently needed. Delaware has an unusually high number of students requiring additional resources to succeed — including students with disabilities, students living in poverty, and English learners. While Delaware spends more than the national average on public education, the funding is not sufficient to meet the needs of these students and their teachers. The evidence is clear. Compared to other states, Delaware ranks near the bottom in reading and math performance, according to the Nation’s Report Card (the National Assessment of Educational Progress). Reading and math scores have been declining for the past decade, with 8th grade reading reaching an all-time low in 2024. Delaware’s spending has not kept up with student needs, and the state struggles to compete with neighboring states for top teaching talent. Beginning teacher salaries are the lowest among nearby states, with even lower salaries in less wealthy communities. Unlike every other state, Delaware does not allocate more funds to districts with less property wealth, further deepening disparities. The stakes are high. Delaware’s students and teachers deserve strong support, and the state’s economy — including businesses, employers, and universities — depends on graduates who are well-prepared for careers and higher education. Delaware’s current school funding system, largely unchanged for 80 years, lags behind reforms enacted in other states. Many states have shifted funding to prioritize student needs and address inequities, resulting in measurable improvements in academic achievement, graduation rates, school climate, and college and career readiness. In the coming months, the Public Education Funding Commission will complete its review and present recommendations to update the funding system. When Governor Matt Meyer — a champion for Delaware’s public schools — sends his recommendations to the General Assembly for consideration, public understanding and engagement will be crucial. –––– Gary Henry is a professor at the University of Delaware and a commissioner on the Public Education Funding Commission.

He has advised various states on education funding including Virginia, North Carolina, Georgia and Texas.

Researchers laying the groundwork to eventually detect cerebral palsy via blood test

At the University of Delaware, molecular biologist Mona Batish in collaboration with Dr. Robert Akins at Nemours Children Hospital, is studying tiny loops in our cells called circular RNAs — once thought to be useless leftovers, but now believed to play an important role in diseases like cancer and cerebral palsy (CP). This is detailed in a new article in the Journal of Biological Chemistry. What are circular RNAs? They’re a special type of RNA that doesn’t make proteins but instead helps control how genes are turned on and off. Because they’re stable and can be found in blood, they may help doctors detect diseases more easily. So what’s the connection to cerebral palsy? CP is the most common physical disability in children, but right now it’s diagnosed only after symptoms appear — there’s no clear-cut test for it. Batish and her team are trying to change that. Working with researchers at Nemours Children’s Health, Batish discovered that in children with CP, a certain circular RNA — circNFIX — is found at much lower levels in muscle cells. This RNA normally helps the body make an important muscle-building protein called MEF2C. When circNFIX is missing or low, MEF2C isn’t made properly, which may lead to the weakened, shorter muscles seen in CP. This is the first time researchers have shown a link between circular RNAs and human muscle development in cerebral palsy. Why does this matter? If scientists can confirm this link, it could lead to: Earlier and more accurate diagnosis of CP using a simple blood test New treatments that help improve muscle development in affected children Batish’s ultimate goal? To create a test that can spot CP at birth — or even before — giving kids a better shot at early treatment and a higher quality of life. To speak to Batish, contact mediarelations@udel.edu.
