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.

Beneficial gut bacteria metabolize fiber to improve heart health in mice
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.
Woodland hawks flock to urban buffet
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.
Study shows movement, evolutionary history of TB in China
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.
Engineers drawn to stem cells’ abundance, humanity
“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.”
Successful mouse couples talk out infidelity in calm tones
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.
Nanoparticles improve tumor treatment in mice
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.
Researchers trace Parkinson’s damage in the heart
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.
Scientists take a journey into the lungs of mice infected with influenza
Using a new tool they call FluVision, UW-Madison researchers can witness an influenza infection in a living animal in action, helping them better understand what happens when a virus infects the lungs and the body responds.
Ebola vaccine inches toward human clinical trials
The need for an Ebola vaccine is acute. Periodic outbreaks of the disease in sub-Saharan Africa, including an epidemic between 2013 and 2016, caused major loss of life and serious economic disruption.
