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.
Middle East air-quality study bridges borders
An unprecedented effort to collect air pollution data in the Middle East has united researchers in a region mired in conflict.
Muscle mass maintenance under scrutiny
When muscles are not pressed into service, they begin to lose mass.
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.
Carbon nanotubes may cheaply harvest sunlight
A new alternative energy technology relies on the element most associated with climate change: carbon.
High-speed genetic analysis looks deep inside primate immune system
Viruses such as HIV and influenza take safe harbor in cells, where they cannot be recognized directly by the immune system. The immune response relies on infected cells announcing the presence of the virus by studding their exterior with fragments of the virus lurking within.
Banded rocks reveal early Earth conditions, changes
The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago.
Scientists hope to mimic nature’s dynamos
In the cosmos, all celestial objects - planets, stars, galaxies and clusters of galaxies - have magnetic fields. On Earth, the magnetic field of our home planet is most easily observed in a compass where the needle points north.
Industrial engineering professor provides national expertise on the driver distraction threat
University of Wisconsin–Madison industrial and systems engineering professor John Lee spoke about the dangers of distracted driving at a Washington, D.C., meeting on the topic held Sept. 30 and Oct. 1. The meeting included representatives from the Obama administration, U.S. Senate and automotive industry, among others, and was a chance for Lee to discuss his area of expertise: technology-mediated attention.
Researcher studies monkeys in Africa to better understand virus evolution
Despite the importance of AIDS in human health, scientists still know very little about the diversity and ecology of AIDS-like viruses in nature.
Sand dunes reveal unexpected dryness during heavy monsoon
The windswept deserts of northern China might seem an odd destination for studying the heavy monsoon rains that routinely drench the more tropical regions of Southeast Asia.
Models begin to unravel how single DNA strands combine
Using computer simulations, a team of University of Wisconsin–Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix.
