In light of the 20th anniversary of James Thomson’s derivation of human embryonic stem cells, we had some questions for one of the founders of stem cell neuroscience.
Nerve cells stripped of their insulation can no longer carry vital information, leading to the numbness, weakness and vision problems often associated with multiple sclerosis. A new study shows an overlooked source may be able to replace that lost insulation.
It’s the first time that the shape of molecules has been used in place of anatomy to organize evolutionary relationships, suggesting new ways to disentangle the many complicated family trees found throughout nature.
In support of a microbial connection between fiber and heart health, UW-Madison researchers have identified a particular fatty acid as the mechanism behind certain protective effects of a high-fiber diet in a mouse model.
A team of Wisconsin researchers documents that woodland hawks — once in precipitous decline — have become firmly established in urban environments, thriving primarily on a diet of backyard birds.
A genetic scan of a massive number of samples taken from tuberculosis patients across China has shown a surprising genetic uniformity: just two “strains” of the tuberculosis bacterium account for 99.4 percent of all cases.
“We very quickly became perhaps the top institution in the country in the stem cell engineering area,” says a leading UW researcher. “That was a field that didn’t exist, and we built it.”
The quality of their conversations between pairs of California mice after one partner has been unfaithful can help predict which mouse pairs will successfully produce a litter of mouse pups and which males are good fathers, according to a new UW-Madison study.
In mouse models of human lung cancer, the improved drug inhibited tumor growth more effectively than the standard drug. “Ultimately, our goal is to get this into human beings,” says pharmacy professor Glen Kwon.
Heart attacks, diabetes and other disorders cause similar damage to nerves in the heart. Those patients and potential therapies could also benefit from the new visualization method, says Parkinson’s disease researcher Marina Emborg.
