They asked, he answered. In his new book, "How Can I Help?: Saving Nature with Your Yard," nationally known University of Delaware entomologist Doug Tallamy addresses the most common questions he receives from homeowners looking to do their part to impact the food web, boost biodiversity and replace invasive plants with native ones.


“Change is afoot!” Tallamy writes in the book, which was released today, April 8. “The cultural change from an adversarial relationship with nature to a collaborative one is starting to happen, and it gives me hope about the future of diversity and thus our own future.”


Tallamy, TA Baker Professor of Agriculture and Natural Resources, wrote “How Can I Help” to tackle questions he’s received over email and during talks he has given around the U.S.


“I get the same questions over and over again,” Tallamy said. “They fall into easily arranged categories: Questions about oaks, questions about ecology, questions about invasive plants. The book almost wrote itself in that sense.”


Some of those common questions include:


• Why should I care about the food web?

• How should I choose the right native plants for my property?

• What is the greatest threat to oaks?

• How do we prioritize which invasive species to get rid of?

• Are bug zappers hurting insect populations?

• Is it better to have fewer plants of lots of species or more plants of fewer species?

• Is it good to feed the birds?

Artemis II and why repeated missions are essential to lunar success

Getting to the moon wasn’t a one-and-done kind of effort. It took repeated missions, each one teaching scientists and engineers something new, and each one making the next attempt a little smarter and a lot safer. That’s a big reason lunar success eventually became possible: people kept going back, gathering more data, fixing problems, and building confidence step by step. With all eyes on the Artemis II mission's final hours, University of Delaware space professor Bennett Maruca can talk all things space exploration and the race to the moon.  Have you ever wondered why Apollo 11 was named Apollo 11? It's because Apollo 1-10 were already taken! And mostly were fact-finding missions, with many barely leaving the ground, says Maruca.  Space program launches can cost billions of dollars. In order to ensure that they are successful, trial runs need to take place. Space travel leaves very little room for guesswork, and even small mistakes can have serious consequences. By launching multiple missions, experts could spot weaknesses, improve hardware, and make sure astronauts were better protected before taking on even bigger risks. In a way, each mission was like a rehearsal that made the final performances much more reliable. Maruca can reveal facts like this and more. He has been featured in multiple publications.

Inside the Italian art heist: Experts explain the global fight to protect cultural heritage

A lightning-fast art heist in Italy has reignited global concerns about museum security and the protection of cultural heritage. As investigators search for stolen works by some of history’s most celebrated artists, University of Delaware experts are available to help journalists unpack the broader implications. Earlier this month, thieves executed a highly coordinated robbery at the Magnani-Rocca Foundation, stealing paintings by Pierre-Auguste Renoir, Paul Cézanne and Henri Matisse in a matter of minutes. Authorities say the operation was swift, targeted and likely premeditated – highlighting the evolving sophistication of art crime. The theft adds to a growing pattern of high-value art crimes across Europe, raising urgent questions about how institutions safeguard collections and what happens when culturally significant works disappear into illicit markets. UD experts are available to provide context, analysis and on-the-record commentary: Debra Hess Norris Chair, Department of Art Conservation A globally recognized leader in art conservation, Norris specializes in the protection, preservation and recovery of cultural heritage. She can speak to: How museums assess and mitigate security risks What happens after a major art theft The challenges of recovering stolen works in international markets How conservation science supports authentication and repatriation Jessica Horton Associate Professor of Art History Horton’s research examines global art histories and the movement of cultural objects across borders. She can discuss: Why stolen artworks matter beyond their monetary value Cultural ownership, repatriation and ethical considerations How art theft disrupts historical narratives and public access The broader cultural consequences of illicit art trafficking While headlines focus on the dramatic nature of art heists, the deeper story is about the fragility of cultural heritage – and the global effort required to protect it.

Robotics help solve deep Sea Mysteries

UD's College of Earth, Ocean and Environment uses robotics currently operated by the National Deep Submergence Facility (NDSF) to study the depths of the ocean. These expeditions ranged from the East Pacific Rise to the Mid-Atlantic Ridge. The vehicles include the Human Occupied Vehicle (HOV) Alvin, the Remotely Operated Vehicle (ROV) Jason and the Autonomous Underwater Vehicle (AUV) Sentry. What it is: A CTD (Conductivity, Temperature, Depth) instrument is a key oceanography tool that collects deep-water samples using remotely triggered Niskin bottles at specific depths. How it helps: These measurements help scientists understand ocean processes, including carbon cycling and life systems, which are essential to understanding Earth’s overall functioning. To find out more or to speak with speak associate professor Andrew Wozniak about this deep-sea technology, reach out to MediaRelations@udel.edu.
