Pecatonica without the ‘P’: Project cuts phosphorus levels in river
Conservation experts and farmers alike are rather pleased with the news out of southwestern Wisconsin. A seven-year pilot project in the 12,000-acre Pleasant Valley subwatershed of the Pecatonica River has helped to reduce the amount of phosphorus and sediment entering the river after major storms by more than a third.
Muddy forests, shorter winters present challenges for loggers
Stable, frozen ground has long been recognized a logger’s friend, capable of supporting equipment and trucks in marshy or soggy forests. Now, a comprehensive look at weather from 1948 onward shows that the logger’s friend is melting. The study, published in the current issue of the Journal of Environmental Management, finds that the period of frozen ground has declined by an average of two or three weeks since 1948.
‘Amazing Race,’ amazing comeback
It wasn't just an "Amazing Race" for Amy DeJong and Maya Warren. It was an amazing victory -- and an amazing comeback.
Neal First, whose work led to cattle cloning, dies at 84
Emeritus Professor Neal First, a pioneer in cattle reproduction and cloning who studied animal physiology at the University of Wisconsin–Madison for 45 years, died Nov. 20 from complications of cancer.
New studies power legacy of UW–Madison mitochondrial research
Dave Pagliarini recently published two studies shedding more light on coenzyme Q and how it’s made, one in the Proceedings of the National Academy of Science (PNAS) in October and another today in Molecular Cell.
Collaboration yields new organic sweet corn variety
When the time comes for Wisconsin’s organic farmers to decide which crops to plant next year, they’ll have a tasty new variety of sweet corn — with a particularly sweet name — among their choices. The new variety, called “Who Gets Kissed?,” is the first in a series of organic, open-pollinated sweet corns being developed through a plant-breeding project led by researchers at the University of Wisconsin–Madison and the Organic Seed Alliance (OSA). Farmers and professional breeders are also involved.
Greater use of social media gets science, scientists noticed, study says
In September, a group of UW–Madison professors and their colleagues published a study in the journal Journalism & Mass Communications Quarterly showing a connection between “h-index” — a measure of the quality of a researcher’s work and influence — and whether the scientists interact with reporters and get mentioned on Twitter.
New process transforms wood, crop waste into valuable chemicals
Scientists today disclosed a new method to convert lignin, a biomass waste product, into simple chemicals. The innovation is an important step toward replacing petroleum-based fuels and chemicals with biorenewable materials, says Shannon Stahl, an expert in "green chemistry" at the University of Wisconsin–Madison.
Wisconsin’s new ‘bug guy,’ insect detective arrives on campus
His favorite insect is one he has actually never seen alive in the wild. It lives on snowfields and glaciers in the American West, aptly named an ice crawler. But PJ Liesch, the University of Wisconsin–Madison’s new “bug guy,” continues to search for it. “I’ve been out West looking for them a couple of times and haven’t had any luck, so they’re kind of one I have on my bucket list, just to see one of those out in the wild,” says Liesch. The insect specialist officially took over as manager of the UW–Madison Insect Diagnostic Lab this summer.
Researchers study vital ‘on/off switches’ that control when bacteria turn deadly
No matter how many times it’s demonstrated, it’s still hard to envision bacteria as social, communicating creatures. But by using a signaling system called “quorum sensing,” these single-celled organisms radically alter their behavior to suit their population. Helen Blackwell, a professor of chemistry at the University of Wisconsin–Madison, has been making artificial compounds that mimic the natural quorum-sensing signals, including some that block a natural signal from binding to its protein target.
Project prepares collection for 21st-century challenge of invasive species
At the Wisconsin State Herbarium, director Kenneth Cameron is spearheading a new, three-year project to “digitize” images and data on aquatic and wetland plants, mollusks and fish from the Great Lakes basin. The $2.5 million grant from the National Science Foundation will also be disbursed to natural history museums at UW campuses in Stevens Point, Milwaukee and La Crosse, and in every other Great Lakes state. Together, these institutions expect to digitize 1.73 million specimens related to Great Lakes invasives.
In directing stem cells, study shows context matters
In a new study, a team of researchers from the University of Wisconsin–Madison has added a new wrinkle to the cell differentiation equation, showing that the stiffness of the surfaces on which stem cells are grown can exert a profound influence on cell fate.
No one-size-fits-all approach in a changing climate, changing land
As climate change alters habitats for birds and bees and everything in between, so too does the way humans decide to use land. Researchers at the University of Wisconsin–Madison and Aarhus University in Denmark have, for the first time, found a way to determine the potential combined impacts of both climate and land-use change on plants, animals and ecosystems across the country.
Science in the Northwoods: Trout Lake Station open house
The first of August was a gorgeous day in northern Wisconsin: temperatures were in the mid-70s, the waters of Trout Lake were remarkably calm and clear, and the mosquitoes, for the first time this summer, were nowhere to be found. It was the perfect day for Trout Lake Station's 4th annual open house.
Project to evaluate how farmers markets benefit communities
A new project in partnership with the University of Wisconsin–Madison and the Farmer's Market Coalition will analyze the impact of farmers markets in communities.
Yeast researcher, Chris Hittinger, named Pew Scholar in Biomedical Sciences
A University of Wisconsin–Madison researcher, well known for his work studying yeast fermentation, has been named a Pew Scholar in the Biomedical Sciences by the Pew Charitable Trusts.
UW students hope to “wok” and paddle to national food contest victories
One team of UW–Madison food science students hopes to "wok" away with a victory, while the other aims to cruise via canoe, as they compete for top honors in two national collegiate food product development competitions held June 21-23 during the Institute of Food Technologists Annual Meeting and Food Expo in New Orleans.
Shaw awards go to two UW researchers
One scientist studying how HIV spreads in the body and another examining cellular machinery and its role in disease have earned funding from the Greater Milwaukee Foundation to advance their research.
UW-Madison chosen to develop curriculum for major dairy training program in China
The University of Wisconsin–Madison has been selected to develop the curriculum for a new $400 million dairy training center being established by the Nestle corporation in China's northeast province of Heilongjiang.
Scientists capture most detailed images yet of tiny cellular machines
A grandfather clock is, on its surface, a simple yet elegant machine. Tall and stately, its job is to steadily tick away the time. But a look inside reveals a much more intricate dance of parts, from precisely-fitted gears to cable-embraced pulleys and bobbing levers.
