Was mighty T. rex ‘Sue’ felled by a lowly parasite?
A new study, published today (Sept. 29) in the online journal Public Library of Science One, provides evidence that ‘Sue,’ the mighty Tyrannosaurus rex whose fossilized remains are a star attraction of the Field Museum in Chicago, was felled by a lowly parasite that still afflicts modern birds.
Curiosities: Why is it that often foods with the least nutritional content taste the best to people?
It depends on how you define nutrition, says Franco Milani, an assistant professor of food science. The word “nutritious” may mean a food…
Capturing tomorrow’s satellite data with today’s instruments
A satellite that won't be launched into orbit until 2015 is already paying dividends for an advanced weather research project.
Smaller isn’t always better: Catalyst simulations could lower fuel cell cost
Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin–Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality.
UW-Madison undergraduates make unwelcome discovery in Lake Mendota
On Sept. 11, a standard cruise on Lake Mendota's University Bay began for students in University of Wisconsin–Madison's Zoology 315, a course that introduces them to the study of lakes. With the sampling craft Limnos anchored about one-quarter mile offshore on a clear sunny day, four students pulled up a small net and began poking through its contents.
Study reveals dynamic Wisconsin climate, past and future
If the future scenarios being churned out by the world's most sophisticated computer climate models are on the mark, big changes are in store for Wisconsin's weather during the next century.
Research aims to cool runoff to protect coldwater streams
The ocean of stormwater that flows off of the sun-baked urban landscape is packing heat, and trout are starting to feel it.
Potato blight reveals some secrets as genome is decoded
Late blight caused the 19th century famine that sparked a wave of emigration from Ireland to the United States, but the disease has also infected tomatoes and potatoes this year. Potatoes, the world's fourth-largest food crop, were raised on 65,500 acres in Wisconsin in 2007. If a potato field is not treated with pesticide, late blight can destroy the crop in a few days.
Monkeys get a groove on, but only to monkey music
Music is one of the surest ways to influence human emotions; most people unconsciously recognize and respond to music that is happy, sad, fearful or mellow. But psychologists who have tried to trace the evolutionary roots of these responses usually hit a dead end. Nonhuman primates scarcely respond to human music, and instead prefer silence.
UW-Madison’s ‘good ideas’ get lift from stimulus funds
The university has drawn more than $38 million in funding for more than 120 research projects and programs from the American Recovery and Reinvestment Act. The work is spread across the range of academic disciplines, including public health, computer science, psychology, economics and engineering. Funding comes from agencies such as NSF, the National Institutes of Health (NIH), the Department of Energy and the National Endowment for the Arts.
Snaring bigger bugs gave flytraps evolutionary edge
Carnivorous plants defy our expectations of how plants should behave, with Venus flytraps employing nerve-like reflexes and powerful digestive enzymes to capture and consume fresh meat. The evolutionary history of these botanical oddities is now a bit clearer, thanks to new work.
Wisconsin team grows retina cells from skin-derived stem cells
A team of scientists from the University of Wisconsin–Madison School of Medicine and Public Health has successfully grown multiple types of retina cells from two types of stem cells - suggesting a future in which damaged retinas could be repaired by cells grown from the patient's own skin.
