It enrolls more than 40,000 undergraduate, graduate and professional students. It is rated by Carnegie Classification of Institutions of Higher Learning as RU/VH which means very high research activity. UW-Madison is rated 17th among universities world-wide and 15th in the Americas by Shanghai Jiao Tong Universities ranking. UW Madison has an exceptional biochemistry, medical and science related graduate division. UW Madison is credited with discovering Vitamin A and Vitamin B by Professor McCollum and cell biologist James Thomson first isolated and cultured embryonic stem cells.
New, inexpensive production materials boost promise of hydrogen fuel
Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains.
Breakthrough harnesses light for controlled chemical reaction
When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants "learned" to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently.
Atom probe assisted dating of oldest piece of earth
(Phys.org) —It's a scientific axiom: big claims require extra-solid evidence. So there were skeptics in 2001 when University of Wisconsin-Madison geoscience professor John Valley dated an ancient crystal found in Australia ...
Deer account for almost half of long-term forest change, study finds
A study released this week has linked at least 40 percent of species changes in the forests of northern Wisconsin and Michigan over the past 60 years to the eating habits of white-tailed deer.
Oldest bit of crust firms up idea of a cool early Earth
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.
Advanced 3-D printer sparks unique collaborations across campus
When the UW-Madison Mechanical Engineering Department acquired an advanced 3D printer in 2012, it not only increased the lab's research capabilities, but it also opened a door to new collaborations on campus.
Dwindling wind may tip predator-prey balance
Bent and tossed by the wind, a field of soybean plants presents a challenge for an Asian lady beetle on the hunt for aphids. But what if the air—and the soybeans—were still?
Actions on climate change bring better health, study says
(Phys.org) —The number of extremely hot days in eastern and midwestern U.S. cities is projected to triple by mid-century, according to a new study led by University of Wisconsin-Madison researchers and published today in ...
Tree killers, yes, fire starters, no: Mountain pine beetles get a bad rap, study says
Mountain pine beetles get a bad rap, and understandably so. The grain-of-rice-sized insects are responsible for killing pine trees over tens of millions of acres in the Western U.S. and Canada over the last decade.
Researchers study vital 'on/off switches' that control when bacteria turn deadly
(Phys.org) —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 ...
