A new study from the University of Wisconsin-Madison refutes the assertion that more undocumented immigrants in the U.S. correlate to an increase in violent crime.

The Waisman Center has a new director. The organization at UW-Madison is one of only 14 Eunice Kennedy Shriver Intellectual and Developmental Disabilities Research Centers in the country. The new director Qiang Chang is our guest. He discusses current research on autism and Rett syndrome and explains how research and clinical service connect. Plus learn about the promise stem cell research holds for degenerative diseases such as ALS.

New research shows tribal forests in northern Wisconsin have older trees, and better plant diversity and tree regeneration than surrounding state or national forests. Researchers with Dartmouth College and the University of Wisconsin-Madison published their findings in a recent issue of the journal Ecology and Society.

One in six of those groups was linked to Russia, according to a University of Wisconsin-Madison study here, and the identities of the rest of the 122 groups that are labeled “suspicious” are still unknown, an indication of the influence of “astroturf” or shell companies in U.S. politics.

When Young Mie Kim began studying political ads on Facebook in August of 2016—while Hillary Clinton was still leading the polls— few people had ever heard of the Russian propaganda group, Internet Research Agency. Not even Facebook itself understood how the group was manipulating the platform’s users to influence the election. For Kim, a professor of journalism at the University of Wisconsin-Madison, the goal was to document the way the usual dark money groups target divisive election ads online, the kind that would be more strictly regulated if they appeared on TV. She never knew then she was walking into a crime scene.

When ecologist John Orrock of the University of Wisconsin–Madison squirted snail slime—a lubricating mucus the animals ooze as they slide along—into soil, nearby tomato plants appeared to notice.

“Venus had plenty of time to evolve life on its own,” said lead author Sanjay Limaye, a planetary scientist at the University of Wisconsin-Madison’s Space Science and Engineering Center, in a press release. In fact, previous research suggests that Venus could have once maintained a habitable climate with liquid water on its surface for as long as 2 billion years. “That’s much longer than is believed to have occurred on Mars,” he said.

Those tallies are particularly interesting given research released this week by Barry Burden of the University of Wisconsin in Madison and Yoshikuni Ono of Tohoku University in Japan. They analyzed the extent to which gender bias affected the underrepresentation of women in elected office using a survey that presented respondents with randomly generated fictional candidates.

But for all the planet’s seemingly inhospitable traits, “Venus has had plenty of time to evolve life on its own,” said University of Wisconsin-Madison scientist Sanjay Limaye, who led the new study, in a press release. Limaye points to models that suggest Venus could have sustained a habitable climate with liquid water on its surface for as long as 2 billion years. “That’s much longer than is believed to have occurred on Mars,” says Limaye.

“Different smiles have different impacts on people’s bodies,” said Jared D. Martin, a doctoral student who led the study in the lab of University of Wisconsin–Madison psychology professor Paula Niedenthal. Along with poker players, psychologists have long known that our facial expressions can betray our emotions. But no one has demonstrated exactly how this works, Mr. Martin said.

Jed Richardson, a scientist with the University of Wisconsin-Madison, and one of the researchers, said high-living costs, including tuition fees in some instances, might explain the results.

The effort to find Fazekas Sr. began in 2014, when University of Wisconsin-Madison researchers succeeded in returning the remains of another soldier to his family. That inspired them to reach out to Department of Defense officials the next year to propose a partnership to find the missing. It would become the university’s Missing in Action Recovery and Identification Project.

The two scientists arrived at the South Pole on November 1 and are part of a team of researchers from UW-Madison working at IceCube all year long. Associate Director of the program Albrecht Karle says the goal of IceCube is to, “Look for extremely energetic neutrinos which appear in energetic processes in the Universe.”
