UW primate research links caloric intake and aging

“Data from both study locations suggest that the [calorie restriction] paradigm is effective in delaying the effects of aging in nonhuman primates but that the age of onset is an important factor in determining the extent to which beneficial effects of [calorie restriction] might be induced,” Ricki Colman, a senior scientist of the WNPRC, commented on the data from the collaborative effort.

DNR revises statement on climate change, concerns UW scientists

Late last December, the Wisconsin Department of Natural Resources revised a statement on their website about climate change, rescinding a portion stating human activity could be a cause. In response, a group of UW-Madison scientists issued a public letter detailing the DNR’s factual inaccuracies in the revised statement and irresponsibility in drastically changing the wording.

A new "luckier" way to build plastics

Professor Ive Hermans has a different philosophy when it comes to running a research group and laboratory full of brilliant students. Most graduate advisers simply tell their students what to do and expect them to follow their directions to a T.

Researcher rethinks lactic acid bacteria

Fermented products can range anywhere from beer to sourdough bread to soy sauce to ethanol fuels. In the microbial realm of fermentation, the process is fundamentally the same: Microorganisms such as bacteria and yeast metabolize sugars into alcohol. But often, the process can be plagued by a major drawback.

Precision therapies advance at UW

By mimicking natural molecular pathways in the human body, scientists at the University of Wisconsin-Madison developed molecular tools that could regulate gene expression. Natural transcription factors bind to genetic sequences and trigger the expression of different genes, which later produce different proteins.

Sciencecast: Climate Change Series - Episode 5

In episode five, we focus on sustainable agriculture and how the food we eat impacts the environment. Instead of meeting with UW experts, we turn to students who are knowledgeable about food insecurity, gardening and farming and the connections between agriculture and climate change.


A section of the UW Hoofers pier, pulled from Lake Mendota in early November, was coated in zebra mussels, an invasive species found in the lake last fall.

Zebra mussels found in Lake Mendota

Lake Mendota had once been the home for swimming, sailing and fishing, among many other recreational and scenic activities. But since the discovery of zebra mussels in the lake by a limnology lab last fall, the lake’s environment has shifted, resulting in changed food sources for fish and less attractive experiences for water activities at the Memorial Union terrace on a summer day. Throughout the summer following the zebra mussel discovery, Lake Mendota had become completely invaded by the mussels, with amounts ranging from 10 zebra mussels per square meter to 60,000 in some areas of the lake, which has created an imbalanced ecosystem, resulting in many future changes to the lake’s ecology and aesthetics.
