Transplanted stem cells show promise for mending broken hearts

December 20, 2005

Working with heart attack-stricken mice, a team of UW–Madison scientists has shown that embryonic stem cells may one day live up to their clinical promise.

Engineered stem cells show promise for sneaking drugs into the brain

December 15, 2005

One of the great challenges for treating Parkinson's diseases and other neurodegenerative disorders is getting medicine to the right place in the brain. UW–Madison neuroscientist Clive Svendsen and his colleagues show how engineered human brain cells, transplanted into the brains of rats and monkeys, can integrate into the brain and deliver medicine where it is needed.

New technologies target food-borne illnesses

December 13, 2005

On its journey to your dinner plate, food is vulnerable to contamination along the way. In 2000, UW–Madison made a commitment to help tackle this complex problem by hiring an interdisciplinary group of researchers with expertise in food safety.

Study suggests treatment for fatal nervous system disorder

December 12, 2005

Working with mice, University of Wisconsin–Madison researchers have developed the basis for a therapeutic strategy that could provide hope for children afflicted with Krabbe's disease, a fatal nervous system disorder.

Dancing bacteria? Engineers explore microbial choreography

December 7, 2005

Birds fly together in flocks. Fish swim together in schools. Everyone has seen the beautiful, seemingly choreographed motions these collections of organisms can exhibit. But surely bacteria, which have no eyes or brain, cannot behave in such a coordinated way. In fact, they do, and researchers are beginning to learn how.

UW-Madison course enhances nonprofits

December 7, 2005

As exam time rolls around, UW–Madison students in the e-Projects in Community Service (ePICS) course won't be studying textbooks or writing take-home finals. They'll be presenting their semester's work to real-world clients, twelve nonprofit organizations for whom students have designed Web sites, built Web-based information systems, created logos, developed marketing materials and produced videos.

Scientists map one of biology’s critical light-sensing structures

November 16, 2005

For plants, the ability to accurately sense light governs everything from seed germination, photosynthesis and pigmentation to patterns of growth and flowering. Now, for the first time, scientists at UW–Madison have obtained a detailed map of one of biology's most important light detectors, a protein found in many species across life's plant, fungal, and bacterial kingdoms.

Lightfoot receives National Medal of Science

November 15, 2005

President George W. Bush has named a UW–Madison professor of chemical and biological engineering as one of eight recipients of the 2004 National Medal of Science, the nation's highest honor for science and technology.

A fatty acid found in milk may help control inflammatory diseases

October 18, 2005

One of the isomers of conjugated linoleic acid, a group of fatty acids found in milk, is a natural regulator of the COX-2 protein, which plays a significant role in inflammatory disease such as arthritis and cancer, according to a study published by UW–Madison researchers.

WiCell receives $16 million NIH grant to create national stem cell bank

October 3, 2005

The WiCell Research Institute has been selected by the National Institutes of Health (NIH) to establish the federal government's first and only National Stem Cell Bank (NSCB), it was announced today at a news conference in Madison.

Nanoscale research receives big boost

September 30, 2005

The National Science Foundation has awarded the UW–Madison Materials Research Science and Engineering Center (MRSEC) nearly $14.8 million over the next six years to continue its leading-edge research on the interfaces of materials at the nanoscale.

Researchers: Deep sleep short-circuits brain’s grid of connectivity

September 29, 2005

In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain - regions that during waking hours are a bustling grid of neural dialogue - apparently lose their ability to communicate effectively, causing consciousness to fade.

Statement from Chancellor John Wiley on Assembly Bill 499

September 28, 2005

The failure of the Wisconsin State Senate to amend Assembly Bill 499, which effectively criminalizes a promising area of biomedical research, sends a frightening message to Wisconsin's research community. Scientists in many fields view this with alarm.

New program in neuroscience and public policy offered

September 13, 2005

Modern neuroscience is advancing understanding of the brain and behavior at a pace that few could have imagined even five years ago. The resulting knowledge is transforming our understanding of brain function in health and disease, with profound implications for society. Recognizing this, two UW–Madison faculty now have created a new dual-degree graduate program in Neuroscience and Public Policy to train students how to apply this knowledge to problems in public policy.

The World’s Tiniest Badger?

September 6, 2005

NanoBucky, created in the research lab of UW–Madison chemistry professor Robert Hamers, is composed of tiny carbon nanofiber “hairs,”each just 75 nanometers in diamete

A single gene controls a key difference between maize and its wild ancestor

August 31, 2005

One of the greatest agricultural and evolutionary puzzles is the origin of maize - and part of the answer may lie in a plot of corn on the western edge of Madison, where a hybrid crop gives new life to ancient genetic material. A UW–Madison genetics team has demonstrated that a single gene, called tga1, controls kernel casing in maize — evidence that modest alterations in single genes can cause dramatic changes in the way traits are expressed.

Study examines public attitudes on nanotechnology

August 30, 2005

Scientists have a rare opportunity to define public discourse over nanotechnology, if they provide citizens with easily digestible information about the emerging technology, a UW–Madison journalism professor says.

Study: Brain structures contribute to asthma attack severity

August 29, 2005

The mere mention of a stressful word like "wheeze" can activate two brain regions in asthmatics during an attack, and this brain activity may be associated with more severe asthma symptoms, according to a study by UW–Madison researchers and collaborators.

Gender hormones may lend to social disorder therapies

August 24, 2005

Researchers at UW–Madison have made the surprising finding that estrogen-and even dopamine, a neurotransmitter-also play critical roles in the development of aggressive social play behaviors. The work may one day help diagnose new autism cases and potentially pave the way for new hormone-based therapeutic approaches that counteract the social difficulties of autism.

New treatment may curb IV-based infections

August 10, 2005

Inserted through the skin and into a vein, long-term intravascular devices such as IV catheters deliver to patients a range of life-saving medications, nutrition and fluids, among other uses. But these life-saving devices also can provide a furtive pipeline for germs from the external world to gain access to the bloodstream of patients. A new finding at UW–Madison may help solve this medical conundrum.
