Cell barrier slows bird flu’s spread among humans
Although more than 100 people have been infected with the H5N1 avian influenza virus, mostly from close contact with infected poultry, the fact that the virus does not spread easily from its pioneering human hosts to other humans has been a biomedical puzzle. Read More
Engineers squeeze secrets from proteins
Proteins, one of the basic components of living things, are among the most studied molecules in biochemistry. Understanding how proteins form or "fold" from sequenced strings of amino acids has long been one of the grand challenges of biology. Read More
Scientists reveal how deadly toxin hijacks cells
Scientists have pinpointed exactly how botulinum neurotoxin A - a potential agent of biological warfare and one of the most lethal toxins known to humans - is able to sneak into cells. Read More
Researcher carves out role of champion of cheese
The most ironic thing about Mark Johnson, one of Wisconsin's leading experts on cheese, is that he spent the first half of his life simply hating the stuff. But the years can change a man and his taste buds. Now, as senior scientist at UW–Madison's Center for Dairy Research, Johnson has devoted his career to enhancing the quality of Wisconsin cheeses.

UW-Madison to launch new influenza research institute
In an effort to bolster what is already recognized as one of the world's top programs of influenza research, UW–Madison announced today plans to launch a new Institute for Influenza Viral Research. Read More
Conference to explore global biological threats
Leading government and academic experts from Washington, D.C. and Madison will address key issues surrounding global biological threats in an all-day symposium April 7 at UW–Madison. Read More
Liquid crystals show promise in controlling embryonic stem cells
Liquid crystals, the same phase-shifting materials used to display information on cell phones, monitors and other electronic equipment, can also be used to report in real time on the differentiation of embryonic stem cells. Read More
Mispairs in genetic material make protein synthesis more efficient
A UW–Madison bacteriologist reveals that mispaired nucleotides in transfer RNA actually make the molecule more adroit, enhancing its ability to build proteins. The paper also illustrates the dynamic nature of genetic material, which is not flat, like an illustration in a textbook, but twists and bends as it interacts with cellular machinery. Read More
New veterinary medicine program supports Wisconsin aquaculture
Friday night fish fries are just one clue that the fish industry, including fish farming, is big business in Wisconsin. UW–Madison's School of Veterinary Medicine is helping launch a new fish health program to protect Wisconsin's growing aquaculture industry. Read More
Great (taste) expectations: study shows brain can manipulate taste
A team of UW–Madison scientists tested the ability of the human brain to mitigate foul taste through a ruse of anticipation. The work, conducted at the UW–Madison Waisman Center using high-tech brain imaging techniques and distasteful concoctions of quinine on a cohort of college students, reveals in detail how the brain responds to a manipulation intended to mitigate an unpleasant experience.

Wisconsin scientists find a way to make human collagen in the lab
A team of scientists at UW–Madison reports the discovery of a method for making human collagen in the lab, opening the door to broader medical applications. Read More
Study explains unexpected conductivity of nanoscale silicon
When graduate student Pengpeng Zhang successfully imaged a piece of silicon just 10 nanometers-or a millionth of a centimeter-in thickness, she and her UW–Madison co-researchers were puzzled. According to established thinking, the feat should be impossible because her microscopy method required samples that conduct electricity. Read More
Darwin’s Day: Making the case for evolution
Just in time for Charles Darwin's 197th birthday, an eminent group of UW–Madison faculty have joined forces to make the case on Feb. 11 for the iconographic scientist and what they consider to be biology's prevailing central idea: Evolution. Read More
From 2D blueprint, material assembles into novel 3D nanostructures
An international team of scientists affiliated with the UW–Madison Nanoscale Science and Engineering Center has coaxed a self-assembling material into forming never-before-seen, three-dimensional nanoscale structures, with potential applications ranging from catalysis and chemical separation to semiconductor manufacturing. Read More
Canine cancer vaccine shows early promise
It wasn't publicized, other than by word of mouth, and still the UW–Madison School of Veterinary Medicine was overwhelmed with requests. Since 1998, the school's oncology department has been producing an anti-cancer vaccine for dogs diagnosed with melanoma. Read More
UW scientists unravel mystery of how flu viruses replicate
With the help of a long-studied flu virus, an electron microscope and a novel idea of how the virus aligns segments of RNA as it prepares to make virions, the particles a virus creates and sends forth to infect cells, one major puzzle of flu virus replication has been resolved. Read More
Mining for gems in the fungal genome
Ever since penicillin, a byproduct of a fungal mold, was discovered in 1929, scientists have scrutinized fungi for other breakthrough drugs. As reported Jan. 20 in the Journal of Chemistry and Biology, a team led by a UW–Madison researcher has developed a new method that may speed the ongoing quest for medically useful compounds in fungi.

Scientists link a gene to degenerative blindness
A team of researchers at UW–Madison has taken a small but crucial step forward in the ongoing fight against retinal degeneration diseases. Read More
Study reveals classic symbiotic relationship between ants, bacteria
Ants that tend and harvest gardens of fungus have a secret weapon against the parasites that invade their crops: antibiotic-producing bacteria that the insects harbor on their bodies,UW-Madison researchers report in today's issue of Science. Read More
