The Top Dino Discoveries Of 2024 | Can Spiking Eggnog Kill Bacteria From Raw Eggs?

To wrap up 2024, science writer Riley Black shares her favorite paleontology discoveries of the year. And, if treated properly, even old-fashioned eggnog made with cream and raw eggs can be a safe holiday beverage.

The Most Exciting Dino Discoveries Of 2024

December is, traditionally, a time to reflect on the events of the past year—including dinosaur discoveries. In 2024, researchers learned more about T. rex and the spiky tails of stegosaurs as well as how dinosaurs evolved, lived, and more.

For Smithsonian Magazine, dinosaur enthusiast and science writer Riley Black rounded up her top dino discoveries of the year. She talks with Ira Flatow about the most exciting paleontology news of 2024.

Can Spiking Eggnog Kill Bacteria From The Raw Eggs?

It’s a question that occasionally comes up over the course of a holiday celebration, at least in certain circles: whether or not the alcohol in old-fashioned eggnog made with real cream and raw eggs can protect against foodborne pathogens such as salmonella.

Around 15 years ago, Science Friday investigated, enlisting the help of a lab at Rockefeller University that has a tradition of mixing up a big batch of old-fashioned eggnog around Thanksgiving, then serving it weeks later at a lab holiday party. The researchers kindly conducted a controlled study in which they deliberately spiked samples of their potent eggnog with salmonella, then followed the mixture’s bacterial status over the course of several weeks.

Science Friday’s Charles Bergquist checks in with Dr. Vincent Fischetti, a bacteriologist at Rockefeller, to see if there have been any advances in the field of eggnogology.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
