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.

New AI model predicts harmful videos before they go viral

Certain short-form videos on major social media platforms can trigger suicidal thoughts among vulnerable viewers, according to new research led by the University of Delaware's Jiaheng Xie. His team developed an AI model that can predict and flag these videos. In the study, published Nov. 17 in Information Systems Research, UD professor Jiaheng Xie and his co-authors showed how AI can assist with safety by predicting high-risk videos before they go viral by looking through both the content and what people write in the comments. • Distinguish what creators choose to post from what viewers think or feel after watching. • Separate known medical risk factors from emerging social media trends, such as viral heartbreak clips or challenges that may influence teens. • This system is especially novel because it predicts the high-risk videos before they reach large audiences. Xie is available for a Zoom interview to share how the model was developed and how it could potentially change the way platforms such as TikTok moderate.

The keys to holiday happiness: Gratitude, giving and genuine connection

The holiday ads insist that it’s the time for cheer, buying gifts and reconnecting with friends and family. Various factors – social media, remote work, politics – have made that more difficult than ever. There is hope: Research by the University of Delaware's Amit Kumar shows the path to genuine happiness this season. Kumar, assistant professor of marketing in UD's Lerner College of Business & Economics, offered the following three strategies. Gratitude: • Gratitude and giving thanks has benefits for both the giver and the receiver. It makes both parties feel good, and provides a real-life human connection at a time when those are hard to come by. "Investing in doing is a better route to social connection than spending on having." - Amit Kumar A shift in gift buying strategy: • Experiences can make for better gifts than trinkets, coats, jewelry or other items. There's a better chance of social connection if you're doing something rather than giving something. Type less, talk more: • It's important to keep in touch, but reconnecting during the holidays through a phone call or face-to-face interaction (virtually or in person) has a better chance of strengthening our bonds.
