Where Does Sand Come From? Parrotfish Poop Makes White Beaches and Now Scientists Know How

Newsweek

Noted: The team, made up of scientists from Lawrence Berkeley National Laboratory, Nanyang Technological University in Singapore and the University of Wisconsin-Madison used a Berkeley X-ray machine known as the Advanced Light Source (ALS) to look at parrotfish teeth. They also used a technique known as polarization-dependent imaging contrast (PIC) mapping to further examine the teeth. PIC was developed by study researcher Pupa Gilbert, a biophysicist and professor in the Physics Department at the University of Wisconsin-Madison, and allowed the researchers to see the parrotfish in a way previously not possible.

Here’s what happened to teachers after Wisconsin gutted its unions

CNN

The unions weathered a similar case that deadlocked last year after the death of Justice Antonin Scalia, and they have since taken steps to build confidence among their membership so they will keep paying dues even if it’s no longer required.

“As a result of the dress rehearsal that they got, they all in their own ways have taken steps to be as prepared as they can be,” says Michael Childers, director of the School for Workers at the University of Wisconsin. “It’s not like they haven’t seen this coming.”

Climate change is here: Wisconsin is seeing earlier springs, later falls, less snow and more floods

Capital Times

Scientists with the University of Wisconsin-Madison’s Initiative on Climate Change Impacts — an effort to identify climate change fallout and offer coping strategies — believe that the effects can be mitigated with reduced greenhouse gas emissions. They believe that policy makers and public agencies can take measures to adapt. But those measures are on indefinite hold. “It’s disappointing, particularly with the shutdown of the DNR science bureau that WICCI collaborated with,” said Michael Notaro, a UW-Madison professor on the front lines of climate research.

The West Will Burn

Outside

Noted: That article led me to the University of Wisconsin-Madison, whose Forest and Wildlife Ecology Lab has been studying wildland-urban interface. One of the lab’s research papers defines that term: “The wildland–urban interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. The WUI is thus a focal area for human–environment conflicts, such as the destruction of homes by wildfires.”

Researchers Build a Cancer Immunotherapy Without Immune Cells

The Scientist

Noted: “In terms of engineering and programming human cell behavior, this is at the cutting edge. It expands our toolkit to rewire cells,” says Krishanu Saha, a biomedical engineer at the University of Wisconsin–Madison who did not participate in the work. “All of the work in this study is in vitro in the lab, but whether that works as well, or perhaps better, inside animals needs further study,” he adds.

Under Trump, Biologists Seek a Low Profile for Controversial Research

MIT Technology Review

Noted: Alta Charo, a professor of law and bioethics at the University of Wisconsin at Madison, said at the meeting that openly debating the rule could “invite some unwanted attention” from the Trump administration and state legislators. “My overriding concern is that this discussion and any action in this area is going to trigger state legislation,” she told members of the National Academies’ committee on technology, policy, and law.

The bitter battle over the world’s most popular insecticides

Nature

Noted: Ultimately, it’s likely that political or regulatory decisions will settle the matter before opposing parties agree, says Sainath Suryanarayanan, an entomologist and sociologist at the University of Wisconsin–Madison who has studied the bee-health issue. “It is a common pattern for highly contentious and polarized debates,” he says.

9 Things You Might Not Know About Landscape Architect Dan Kiley’s Enduring Milwaukee Legacies

Milwaukee Magazine

The UW-Milwaukee’s School of Architecture & Urban Planning (SARUP) this month hosted an all-day symposium about Kiley’s work and its continuing relevance. It was held in conjunction with the opening of the traveling exhibition, “The Landscape Architecture Legacy of Dan Kiley” curated by The Cultural Landscape Foundation based in Washington, D.C. Speakers included landscape architects from around the country, including keynoter Peter Ker Walker of Burlington, Vermont, Kiley’s former longtime professional partner.

4 ways Scott Walker could lose in 2018

Appleton Post-Crescent

Noted: “I think one of Walker’s strengths in the past is that he was viewed as independent, separate from Washington, as a common sense guy,” said Barry Burden, a political science professor at the University of Wisconsin-Madison. “The themes in his earlier campaigns were about the old Saturn he drove, eating a packed lunch, understanding an average Wisconsinite. It’s harder to sell that message if you’re visiting the White House a lot and allied with a controversial billionaire who’s now president.”

The Rev-Up: Imagining a 20% Self-Driving World

New York Times

Noted: As drivers interact with semiautonomous vehicles in the long run-up to Level 5, driver education and licensing, far from becoming obsolete, may become more important, argues John D. Lee, a professor of engineering at the University of Wisconsin-Madison. “Automation has a strong tendency to surprise people with unexpected behavior,” he says.

Why So Many People Choose the Wrong Health Plans

New York Times

Noted: Simply providing consumers with good options doesn’t ensure that they will choose wisely. Three economists, Saurabh Bhargava and George Loewenstein of Carnegie Mellon University and Justin Sydnor of the University of Wisconsin, examined the problem in a 2017 paper. They studied an anonymous, large company that gave employees many choices.

Treatment for Depression: Mindfulness Therapy is Still Unproven Because of Flimsy Research

Newsweek

Noted: “There is quite a bit of discussion about mindfulness and mindfulness research these days,” Simon Goldberg told Newsweek. Goldberg is one of the authors of the PLoS One paper and conducted the study while a PhD student at the University of Wisconsin—Madison’s Center for Healthy Minds. (He’s since received his doctorate.) “Our hope ultimately is that the results from our study can help encourage researchers to implement some of these recommended practices in future studies.”

Can math be used to predict an outbreak?

Milwaukee Journal Sentinel

Quoted: “I would say that algorithms and mathematical modeling are fairly pervasive and ubiquitous, from the time someone wakes up in the morning until the end of the day,” said Anthony Gitter, an assistant professor in the department of biostatistics and medical informatics at the University of Wisconsin-Madison.

The Grassroots Social Network Documenting Real-Time Climate Change

Pacific Standard

Noted: After taking a look, the lab asked her to freeze the birds and send them in. In conjunction with the University of Wisconsin–Madison wildlife laboratory, researchers identified the worms as the parasite nematode Splendidofilaria pectoralis, which is found in warmer-climate species. The researchers saw the appearance of the disease as an indicator of the rapidly changing climates in northern areas and published an article based on the findings in the Ecological Society of America Journal, all based on Kotongan’s original post on the LEO network.

Storm Chasers, Megacomputers, and the Quest to Understand Extreme Weather

Wired

Noted: A dozen or so years later, when he arrived at the University of Wisconsin–Madison and fell in love with coding, he learned about the community of scientists who had been using computers to simulate storms since the 1970s. In the earliest renderings, most computers couldn’t re-create any features of a tornado that were less than a kilometer wide or tall, meaning they could re-create the broad contours of a storm but none of its important details. Over time, driven in part by advances in microprocessing power, scientists gradually sharpened the resolution from 1 kilometer to 500 meters and eventually to 100 meters, the storm and the tornado steadily coming into focus.

What is a ‘species’ anyway?

Science News

Noted: And plant reproduction, oy. The blends of sex and no-sex don’t fit into a tidy biological species concept. Consider a new variety of a western North American species that Ertter and botanist Alexa DiNicola of the University of Wisconsin–Madison named this year. Potentilla versicolor var. darrachii belongs to a genus that’s closely related to strawberries. Plants in the genus open little five-petaled flowers and readily form classic seeds that mix genes from pollen and ovule. On occasion, though, the genes in the seed’s embryo are only mom’s. “They basically use seeds as a form of cloning,” Ertter says. The male pollen in these cases merely jump-starts formation of the seed’s food supply.

Upcoming festivals focus on the intersection of art and science

Portage Daily Register

Another featured author, UW-Madison professor Jason Fletcher, has a different take on science’s role in today’s society as he looks through the lens of genetics. His book, “The Genome Factor,” examines the ways in which genetics advances are transforming the social sciences. He cites the recent rise in companies that offer cheap DNA testing like 23andMe and ancestry.com as factors in a genomic revolution.

Prominent Educator Recognized by Alma Mater

Diverse Issues in Higher Education

Dr. Jerlando F.L. Jackson—an expert on workforce diversity and workplace discrimination in higher education—and a prolific researcher on issues relating to Black males, was awarded the Alumni Achievement Award from the College of Human Sciences at Iowa State University.

Crohn’s Disease Causes: Is Fungus a Factor?

Everyday Health

Noted: David Andes, MD, the chief of the division of infectious diseases at the University of Wisconsin School of Medicine and Public Health in Madison, says the term he likes for this imbalance is “dysbiosis.” “It’s not that there weren’t fungi there before, but now there are different fungi and different bacteria, in different proportions,” Dr. Andes says. “And when they experimentally combined the fungi and bacteria they found in patients with Crohn’s disease, they provoked inflammation, which may contribute to the disease process in Crohn’s.”

An inconvenient truth? China omits key figures that may have highlighted its demographic time bomb from official statistics

South China Morning Post

Noted: Yi Fuxian, a long-term critic of China’s birth control policy and a researcher at the University of Wisconsin-Madison in the United States, caused a stir in May by saying that China’s population size had been overestimated by 90 million, and that China’s real population may be smaller than India’s.

Scientists Seek To Solve Marten Mystery On The Apostle Islands

WPR

This fall, UW-Madison began a four-year project to find out whether martens on the Apostle Islands are relatives of those that were introduced in the 1950s. It’s also possible the animals came from a group of martens that were reintroduced into northern Wisconsin’s Chequamegon-Nicolet National Forest, according to Jon Pauli, assistant professor in the Department of Forest and Wildlife Ecology at UW-Madison.

Profit and Loss: Why Some Industries Fare Better Than Others

NerdWallet

Quoted: For example, in the death care services industry (10.8% profit margin), which includes businesses such as funeral homes and crematories, price wars are less intense because customers make decisions more quickly based on emotions and are less likely to shop around, says Dan Olszewski, director at the Weinert Center for Entrepreneurship at the Wisconsin School of Business.

Why Doing Good Is Good for the Do-Gooder

New York Times

Noted: Dr. Richard Davidson, a neuroscientist and founder of the Center for Healthy Minds at the University of Wisconsin, Madison, has been studying the effects of positive emotions, such as compassion and kindness, on the brain since the 1990s. He said the brain behaves differently during an act of generosity than it does during a hedonistic activity.

A new tool for editing DNA, one base at a time

Los Angeles Times

Noted: The new work is significant because it will allow scientists to use base editing to address many more single-letter mutations than was previously possible, said Krishanu Saha, a biomedical engineer at the University of Wisconsin Madison who was not involved with the research.

The Meaning of Betsy DeVos’ Rollback on Disability Rights

Pacific Standard

Noted: Without guidance, as observed on Twitter by Donald Moynihan, professor of public affairs at the University of Wisconsin–Madison, states and schools have “de-facto-discretion … to deny access to services.” Moreover, Moynihan added, given Attorney General Jeff Sessions’ long-stated hostility to the Individuals with Disabilities Education Act as “the single most irritating problem for teachers,” we can’t look to the Department of Justice for help when the Department of Education fails to guide local districts.
