Leaf-cutter ants, which cultivate fungus for food, have many remarkable qualities.
Sweet corn story begins in UW–Madison lab
This week, scientists are revealing the genetic instructions inside corn, one of the big three cereal crops. Corn, or maize, has one of the most complex sequences of DNA ever analyzed, says University of Wisconsin–Madison genomicist David Schwartz, who was one of more than 100 authors in the article in the journal Science.
After mastodons and mammoths, a transformed landscape
Roughly 15,000 years ago, at the end of the last ice age, North America's vast assemblage of large animals - including such iconic creatures as mammoths, mastodons, camels, horses, ground sloths and giant beavers - began their precipitous slide to extinction.
Warmer means windier on world’s biggest lake
Rising water temperatures are kicking up more powerful winds on Lake Superior, with consequences for currents, biological cycles, pollution and more on the world's largest lake and its smaller brethren.

Researchers at the University of Wisconsin–Madison School of Medicine and Public Health have eliminated cervical cancer in mice with two FDA-approved drugs currently used to treat breast cancer and osteoporosis.
Now hear this: Mouse study sheds light on hearing loss in older adults
Becoming "hard of hearing" is a standard but unfortunate part of aging: A syndrome called age-related hearing loss affects about 40 percent of people over 65 in the United States, and will afflict an estimated 28 million Americans by 2030.
Fifty years of expanding girls’ horizons in science, math
The Expanding Your Horizons program, a daylong conference designed to expose young women to careers in science, technology, engineering and math, has touched thousands of Wisconsin women during its 50-year history at UW–Madison.

Curiosities: Is there a limit to how fast humans can be?
“In my opinion there are no limits,” says Tim Gattenby, a faculty associate in kinesiology at UW–Madison. “People said that no one could…
New material could efficiently power tiny generators
To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components is critical to the performance of the overall device.
War of the viruses: Could ancient virus genes help fight modern AIDS?
Almost 30 years into the AIDS epidemic, scientists have yet to find an effective vaccine against HIV, the virus that destroys the immune system and causes AIDS. HIV is perhaps the most adaptive virus ever seen, not only evading the immune system, but also antiviral medicines.
Carbon nanotubes may cheaply harvest sunlight
