Empowering a reliable, cost-effective electricity grid today while paving the way for a renewable future

Extreme heat is stretching the United States' electricity infrastructure to maximum capacity, and the reported disjointedness of the country's three electric grids has made it more difficult to deliver wind and solar power as reinforcements.


Willett Kempton, professor of marine science and policy at the University of Delaware, led the development of a way to use electric car batteries to make grids more stable and resilient. Kempton advocates using electric storage through V2G technology to make electricity more reliable at a lower cost today and to enable the grid to use more renewable energy in the future.


Kempton, associate director of vehicle-to-grid (V2G) technology for UD's Center for Research in Wind (CReW), pioneered technology for vehicle-to-grid (V2G) vehicles, which are capable of absorbing excess energy when demand for power is low and returning some back to the electric grid when the demand for power is high.

Vitamin D in pregnancy may boost kids’ brainpower

You don't need a scientist to tell you that milk is good for babies. But a new study led by the University of Delaware's Melissa Melough sheds light on the power of prenatal nutrition — specifically vitamin D— as a key contributor to children’s brain development. The research found that children whose mothers had higher vitamin D levels during pregnancy scored better on tests of memory, attention and problem-solving skills at ages 7 to 12 compared with those whose mothers had lower levels. Melough wrote about the study in a piece for The Conversation. Vitamin D deficiency affects 42% of U.S. adults and about a third of pregnant women, but the average American woman consumes just 168 international units of vitamin D daily (the recommended amount is 600 ID). Many prenatal vitamins contain only 400 IU. One promising finding could result in the solution of a racial disparity in nutrition. The study found a link between prenatal vitamin D levels and childhood cognition was strongest among Black families, who also face higher rates of vitamin D deficiency. Therefore, vitamin D supplementation could be a low-cost strategy to support brain development while reducing racial disparities. Melough is available for interviews about the study, and can also speak to the following topics: • Nutritional and environmental factors influencing human health. • Populations at risk for nutritional inadequacies or harmful environmental exposures. • The roles of endocrine disruptors in the development of obesity. • The influences of maternal nutrition on childhood outcomes • Novel dietary approaches to reduce chemical exposures or their associated health consequences.

Pets and the Texas floods: Owners faced difficult decisions and loss during and after disaster

One of the more overlooked aspects of any disaster is the loss of pets. Many of them become separated from their owners, are badly injured or perish as the result of a hurricane, flood, earthquake or other major event. This was the case in the recent flooding of the Guadalupe River in central Texas, said Sarah DeYoung, core faculty with the University of Delaware's Disaster Research Center. DeYoung can talk about the following aspects related to the tragedy: • The decisions that people have to make during evacuation, particularly for those with companion animals. • The amount of horses along the Guadalupe River, which could be found at the camps and recreation areas. • Pets that go missing after a flash flood, and the role that key organizations play in response and tracking and managing logistics. • The psychological impact on people whose pets were injured or died, who are mourning and making memorials. DeYoung can also discuss maternal and child health in crisis and disaster settings with a focus on infant feeding in emergencies.

What X chief executive's sudden exit means for the future of the social media giant

A sudden CEO departure almost always causes shockwaves. But the unexpected July 9 exit of X chief executive Linda Yaccarino after just two years – especially without a meaningful explanation – suggests instability or deeper dysfunction, says Lawrence Cunningham, director of the University of Delaware's Weinberg Center for Corporate Governance. Cunningham said the immediate questions are what was the succession plan, and is it now being executed? "Or was there no plan, which itself is a governance failure? Boards have a duty to prepare for transitions, especially in volatile environments. If succession planning was absent or inadequate, more departures may follow," he said. Cunningham can discuss the following topics in regards to Yaccarino's departure: • What a short CEO tenure signals about board oversight and strategic misalignment. • The role of succession planning – and what it means if none was in place. • Why reputational risk and cultural tone at the top matter in retaining leadership. • How boards should respond to external controversies affecting company values.
