Letting off steam: Gas discharge terminates galaxy’s star formation
With the help of a radio telescope in the French Alps, an international team of astronomers, including two from the University of Wisconsin–Madison, has observed a never-before-seen stage of galactic evolution. Writing in this week’s Nature, a group that includes UW–Madison astronomers Aleks Diamond-Stanic and Christy Tremonti, reports measurements of dense, cold hydrogen gas being blasted from a distant star-forming galaxy, the first direct observation of the “blow out” phase of a galaxy’s evolution.
Computer equal to or better than humans at cataloging science
In 1997, IBM’s Deep Blue computer beat chess wizard Garry Kasparov. This year, a computer system developed at the University of Wisconsin–Madison equaled or bested scientists at the complex task of extracting data from scientific publications and placing it in a database that catalogs the results of tens of thousands of individual studies.
UW team explores large, restless volcanic field in Chile
If Brad Singer knew for sure what was happening three miles under an odd-shaped lake in the Andes, he might be less eager to spend a good part of his career investigating a volcanic field that has erupted 36 times during the last 25,000 years. As he leads a large scientific team exploring a region in the Andes called Laguna del Maule, Singer hopes the area remains quiet.
Study models the past to understand the future of strengthening El Niño
El Niño is not a contemporary phenomenon; it’s long been the Earth’s dominant source of year-to-year climate fluctuation. But as the climate warms and the feedbacks that drive the cycle change, researchers want to know how El Niño will respond. A team of researchers led by the University of Wisconsin’s Zhengyu Liu will publish the latest findings in this quest Nov. 27 in Nature.
Telescopes hint at neutrino beacon at the heart of the Milky Way
Thanks to a confluence of data from a suite of vastly different telescopes, there are tantalizing clues that the massive black hole at the core of the Milky Way may be a cosmic accelerator. In a recent paper published in the journal Physical Review D, a team led by University of Wisconsin–Madison physicist Yang Bai reports a correlation of IceCube data with a recorded burst of X-rays from Sagittarius A, an object at the center of our galaxy that is believed to be a supermassive black hole.
Save power, make power: UW chemist confronts ambitious agenda with a brash laugh
Trisha Andrew, a UW assistant professor of chemistry, holds a solar cell that her research group printed on paper last year. She’s currently…
Grasshoppers signal slow recovery of post-agricultural woodlands, study finds
New research by Philip Hahn and John Orrock at the University of Wisconsin–Madison on the recovery of South Carolina longleaf pine woodlands once used for cropland shows just how long lasting the legacy of agriculture can be in the recovery of natural places. By comparing grasshoppers found at woodland sites once used for agriculture to similar sites never disturbed by farming, Hahn and Orrock show that despite decades of recovery, the numbers and types of species found in each differ.
AAAS honors four UW–Madison professors for advancing science
Four members of the University of Wisconsin–Madison faculty have been elected fellows of the American Association for the Advancement of Science (AAAS), the society announced today.
Satellite history at UW–Madison comes full circle with award
Michael Pavolonis thinks of himself as a volcano guy.
Ecologist/hunter talks deer, plants, hunters and balance
UW-Madison Professor of Botany Donald Waller is a pioneer in exploring the impact of deer in natural habitats. For more than 20 years, Waller - who counts himself among the state's deer hunters - has led research on the economic, health and environmental impacts of deer, including:
Halting the hijacker: Cellular targets to thwart influenza virus infection
The influenza virus, like all viruses, is a hijacker. It quietly slips its way inside cells, steals the machinery inside to make more copies of itself, and then - having multiplied - bursts out of the cell to find others to infect.
Full color 3-D printing takes top prize in Collegiate Inventors Competition
Innovative 3-D printing technology came out on top as Spectrom - developed by a University of Wisconsin–Madison team that includes Cedric Kovacs-Johnson, Charles Haider and Taylor Fahey - won first place in the undergraduate category of the Collegiate Inventors Competition.
Crops play a major role in the annual CO2 cycle increase
In a study published Wednesday, Nov. 19, in Nature, scientists at Boston University, the University of New Hampshire, the University of Michigan, the University of Minnesota, the University of Wisconsin–Madison and McGill University show that a steep rise in the productivity of crops grown for food accounts for as much as 25 percent of the increase in this carbon dioxide (CO2) seasonality.
Imagination, reality flow in opposite directions in the brain
As real as that daydream may seem, its path through your brain runs opposite reality. Aiming to discern discrete neural circuits, researchers at the University of Wisconsin–Madison have tracked electrical activity in the brains of people who alternately imagined scenes or watched videos.
Scientists get to the heart of fool’s gold as a solar material
As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity.
Grad program honored for closing science-society gap
The University of Wisconsin–Madison’s Neuroscience and Public Policy Program was honored by the Society for Neuroscience with the Neuroscience Graduate Program Achievement Award.
Morgridge scientists find way to ‘keep the lights on’ for cell self-renewal
One remarkable quality of pluripotent stem cells is they are immortal in the lab, able to divide and grow indefinitely under the right conditions. It turns out this ability also may exist further down the development path, with the workhorse progenitor cells responsible for creating specific tissues.
