Shark Week: Ocean predators go from villains to heroes, helping to predict hurricanes

Just in time for Shark Week, the ocean's most famous predators are experiencing a redemption arc. Marine ecologists at the University of Delaware have fitted sharks with sensors and sent them out into the Atlantic Ocean to gather data that could help predict hurricanes. The research is led by UD professors Aaron Carlisle and Matt Oliver and PhD student Caroline Wiernicki.


Enlisting sharks as amateur meteorologists comes at a critical time. The National Oceanic and Atmospheric Administration's capacity to forecast hurricanes has been hampered by federal cuts to staff and funding.


Sharks also help speed things up. NOAA has partnered with UD and other Mid-Atlantic universities, which deploy gliders to the continental shelf to collect data that tell researchers what the water column looks like as hurricane season approaches.


The gliders are effective but also slow moving and expensive to deploy and maintain.


The researchers have successfully deployed three tags: two conductivity, temperature and depth (CTD) tags on two mako sharks (for oceanographic data collection); and a satellite tag on one white shark (to help evaluate if that species would be a good candidate for CTD tagging down the road).


As of July 21, the white shark has been pinging the research team ever since he was tagged in May. He was recently tracked off Martha's Vineyard and has been surfacing every day – showing up in areas like Cape Cod and Long Island. The mako sharks were tagged off of the Delaware coast and swam south, bopping up and down between the Delmarva Peninsula and just north of Cape Hatteras.

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.
