Most schools make grade in new report cards

Milwaukee Journal Sentinel

Noted: This was the first year DPI used a variable weighting system and value-added analysis to address the impact of poverty on student achievement. Under this system, the higher the percentage of economically disadvantaged students in a school or district, the higher the weight on student-growth scores. The method for calculating student growth was created by the Value-Added Research Center at the University of Wisconsin-Madison.

Battling buckthorn

Isthmus

There’s not a lot to like about the stout, spiked branches of the aggressively invasive buckthorn tree. “Buckthorn is spreading actively across the landscape, facilitated by birds eating the berries and spreading seeds,” says Mark Renz, assistant professor of agronomy at UW-Madison and a UW-Extension weed specialist. “The way it is changing the forest understory is really an epidemic in the upper Midwest.”

UW researchers to study voter ID effect

Milwaukee Journal Sentinel

University of Wisconsin-Madison researchers are taking up a tricky task after last Tuesday’s election: figuring out whether the presence of the state’s voter ID requirement affected who voted.

River fish feed millions

Nature

Peter McIntyre at the University of Wisconsin, Madison, and his colleagues used data from the Food and Agriculture Organization of the United Nations to build a global map of river fisheries, which have historically received less attention than their marine counterparts. They found that pressure from fishing was most intense in areas where biodiversity was also highest, raising concerns about conservation.

Why Do Raccoons Flourish As Urban Pests?

Wisconsin Public Radio

In Wisconsin, like most of the country, Raccoons are practically omnipresent. Their adaptability has allowed them to move from the country landscape as a wildlife creature to an urban life in cities and towns across the state. There are a few factors that make the raccoon especially adept at finding the food and shelter they need living among people, said University of Wisconsin-Madison professor David Drake.

Wisconsin puts inventive art on display

Big Ten Network

Since 1925, the Wisconsin Alumni Research Foundation has racked up quite a roster of patents. That’s kind of the point. A nonprofit institution, WARF exists to support scientific investigations and research at the University of Wisconsin-Madison by stewarding a “cycle of research, discovery, commercialization and investment.”

Using wood pulp and footsteps, a professor just found a new source of renewable energy

Digital Trends

While thousands of people the world over continue to go solar to generate alternative energy, a lab at the University of Wisconsin-Madison just made a major breakthrough on a completely unique new conductive material: wood pulp. While the mention of wood pulp mention leave many scratching their head, the lab found a way to manufacture floorboards out of the commonly wasted material, and did so in a manner that took advantage of its composition of cellulose nanofibers. In other words, the team of engineers managed to develop a flooring material capable of generating electricity by something as simple as a footstep.

Researchers Developing Camera to See Around Corners

National Defense Magazine

For a soldier patrolling a city street in a warzone, seeing what’s around the corner of a building could be the difference between life and death. The Morgridge Institute for Research and the University of Wisconsin-Madison are collaborating to make a camera that can recreate scenes that are out of sight using what is known as scattered light technology. The project is being supported by a $4.4 million grant from the Defense Advanced Research Projects Agency.

It’s Official: Three-Toed Sloths Are the Slowest Mammals on Earth

Scientific American

After seven years of studying three-toed sloths, scientists at the University of Wisconsin–Madison have made it official: the tree-dwelling animals are the slowest mammals on earth, metabolically speaking. “We expected them to have low metabolic rates, but we found them to have tremendously low energy needs,” says ecologist Jonathan Pauli.

Wisconsin is a hotbed of stem cell issues

Appleton Post Crescent

Recent legislative attempts in Madison would make it a state crime to donate fetal tissue derived from abortions or do research on tissue lines. It also proposes prosecution of researchers using this type of tissue. The dean of the UW Medical school, Robert Golden, said researchers follow ethical guidelines and federal law and hope to someday eliminate the use of fetal tissue.

Fetal cell lines were critical in the development of the polio vaccine and other types of fetal tissue research have saved countless children from the devastation of infectious diseases. But now, many of these types of vaccines could be at risk if the bill just proposed in the Wisconsin Legislature becomes law.

UW-Madison teams snag innovation awards

Milwaukee Journal Sentinel

Two research teams — one with a potential vaccine for the Zika virus and the other with a new way of monitoring sedated patients — have won $10,000 each in an innovation competition organized by the Wisconsin Alumni Research Foundation.

Uncovering the Secrets of Mammoth Island

Discover Magazine

Noted: Each meter of cored sediment reaches further back in time. As team member Jack Williams of the University of Wisconsin-Madison guides the sixth segment into a tube, he notices the mud changes from a warm brown with a pudding-like texture to a blacker, firmer consistency. The team estimates it corresponds to deposits from roughly 6,000 to 8,000 years ago, spanning the period when Graham’s mammoth died in the cave. That means this segment could include the period of extinction, if mammoth DNA is present in its lower, older layers but absent from the top. “There’s mammoth in there,” Williams predicts.

Rewiring the brain

On a snowy Friday morning in 2005, Jeri Lake was riding her bicycle to the clinic where she worked as a nurse and midwife when a car suddenly drove into her path.

Worming their way into Wisconsin

Isthmus

When local gardeners turn over a spade of soil, they’re usually happy to find an earthworm or two. While these familiar worms were brought over by European settlers and are not beneficial to native habitat, they can form a healthy partnership with plants that farmers and gardeners have come to depend on.

Stress control

Isthmus

Seven and a half hours of boredom, plus 30 minutes of terror. That’s how Dr. Michael Spierer, a Madison-based psychologist, describes the typical police officer’s shift. Eight hours of paperwork and petty crime, with the knowledge that a high-pressure and dangerous turn of events may be just around the corner. Chronic stress is inherent to the job, he says.

Dairy Sheep Research Coming To An End In Spooner

Wisconsin Public Radio

David Thomas is looking over his life’s work at the Spooner Agricultural Research Station in northern Wisconsin. After 26 years with the University of Wisconsin-Madison, the professor of sheep genetics and management is retiring and the research station’s dairy sheep program is going along with him.

How Climate Change Is Cranking The Heat On Public Health Crises

Here & Now

Droughts, floods and heat waves are becoming more common in various parts of the world thanks to climate change. As part of our weeklong look at climate change, Here & Now’s Jeremy Hobson talks with Dr. Jonathan Patz, director of the Global Health Institute at the University of Wisconsin-Madison, about the public health impacts of global warming.

GAO finds more gaps in oversight of bioterror germs studied in U.S. labs

USA Today

Government regulators have no idea how often laboratories working with some of the world’s most dangerous viruses and bacteria are failing to fully kill vials of specimens before sending them to other researchers who lack critical gear to protect them against infection, according to a new report by the Government Accountability Office.

Effort fights ‘epidemic’ of deadly elderly falls

Milwaukee Journal Sentinel

Noted: While studies are underway and advocacy groups and others scramble for better answers, specialists with the University of Wisconsin-Madison have teamed up with their counterparts in Oregon, as well as with the federal Centers for Disease Control and Prevention and health care records software giant Epic Systems, to build a program that helps predict whether an older person will fall. It not only calculates the risk — it steers physicians to preventative treatments.
