The end of the year is a time of holiday gift giving, and finding just the right gift can sometimes feel like an impossible task. But folks at an animal eyeball lab say that a gift they’ve just received, partly thanks to NPR, has made this the “best Christmas ever.”

“The difference in carbon isotope ratios correlate with their shapes,” said John Valley, professor of geoscience at the University of Wisconsin-Madison and co-author of the study. “Their C-13-to-C-12 ratios are characteristic of biology and metabolic function.”

Just look at the work done by Badgerloop, a student-run hyperloop team out of the University of Wisconsin–Madison. The group’s maglev design uses Halbach arrays in a novel fashion, says technical director Justin Williams, allowing for passive movement, as opposed to superconducting magnets that require a flow of electricity to work. It could significantly reduce the amount of energy required to propel a levitating train. The team won an innovation award at Elon Musk’s hyperloop competition in January.

University of Wisconsin-Madison scientists have helped confirm that tiny fossils detected in an Australian rock are the oldest fossils ever found.

“People are really interested in when life on Earth first emerged,” John W. Valley, a professor of geoscience at University of Wisconsin-Madison and author on the study told said in a statement. “This study was 10 times more time-consuming and more difficult than I first imagined, but it came to fruition because of many dedicated people who have been excited about this since day one … I think a lot more microfossil analyses will be made on samples of Earth and possibly from other planetary bodies.”

To the PI, failure is the albatross that hangs around one’s professional neck. The PI in this case is Francis Halzen, of the University of Wisconsin, an “oracular” presence, Mr. Bowen tells us, whose formidable intellect gushes forth in scientific forums: “Ideas splashed across his mind so fast that his mouth couldn’t keep up.”

One morning seven years ago, Tony Goldberg was working in the tropical forests of Uganda’s Kibale National Park, when a colleague arrived at his research station with two students in tow. They were searching for bats. Goldberg, a University of Wisconsin-Madison professor of epidemiology, had been visiting the station for several years, long enough to have noticed the jet-black figures that fluttered away from the kitchen building whenever he disturbed their daytime sleep.

When Charles Konsitzke and Dhanu Shanmuganayagam first met, they were both just trying to get some peace and quiet. It was early 2014, and they were representing the University of Wisconsin-Madison at a fancy event to promote the university’s research to local politicians. After hours of talking to senators, Shanmuganayagam was fried, and went for a walk to clear his head. That’s when he bumped into Konsitzke, an administrator at the University of Wisconsin’s Biotechnology Center. They introduced themselves, and discussed their work. Shanmuganayagam said that he ran a facility that rears miniature pigs, which are genetically engineered to carry mutations found in human genetic disorders. Scientists can study the mini-pigs to better understand those diseases.

Allison Stegner, a researcher at the University of Wisconsin-Madison, studies packrat middens in the Bear’s Ears national monument. That might sound cute, but the research involves anything but fuzzy rodent gloves. These small mammals collect carnivore bones, coyote poop, and the regurgitations of raptors and owls. “It’s really charming,” says Stegner.

Stegner says that oil and gas mining pose a threat to the rare fossil beds in Bear’s Ears, which shed light on how different species once interacted. “I have no problem with multi-use land in any way, but I do have a problem with giving over this incredible place, that is so important culturally and scientifically, to [serve] the interests of a few people,” she says.

Around 15 years ago, University of Wisconsin-Madison psychologist Seth Pollak recruited a couple hundred children to study the relationship between childhood stress and certain immune system markers. “We had a whole range [of participants], from kids with really boring, stable, average lives all the way up to kids with severe child abuse, and neglect, and poverty, and really extreme childhood stressors,” Pollak says. He published his research in the esteemed journal Proceedings of the National Academy of Sciences (PNAS).
