Is There Life Adrift in the Clouds of Venus?

University of Wisconsin-Madison

In the search for extraterrestrial life, scientists have turned over all sorts of rocks. Mars, for example, has geological features that suggest it once had — and still has — subsurface liquid water, an almost sure prerequisite for life. Scientists have also eyed Saturn’s moons Titan and Enceladus as well as Jupiter’s moons Europa, Ganymede and Callisto as possible havens for life in the oceans under their icy crusts. Now, however, scientists are dusting off an old idea that promises a new vista in the hunt for life beyond Earth: the clouds of Venus.

Spiders and Scorpions Have Co-Opted Leg Genes to Build Their Heads

University of Wisconsin-Madison

University of Wisconsin–Madison researchers Emily Setton and Prashant Sharma show that the common house spider and its arachnid relatives have dispensed with a gene involved in creating segmented heads, instead recycling leg genes to accomplish the task.

Decades of Research Identify Source of Galaxy-Sized Stream of Gas

University of Wisconsin-Madison

A cloud of gas 300,000 light-years long is arching around the Milky Way, shunted away from two dwarf galaxies orbiting our own. For decades, astronomers have wanted to know which of the two galaxies, the Large and Small Magellanic Clouds, is the source of the gas that has been expelled as the two galaxies gravitationally pull at one another. The answer will help astronomers understand how galaxies form and change over time.

Liquid-to-Glass Transition Process Gains Clarity

University of Wisconsin-Madison

Paul Voyles, the Beckwith-Bascom Professor in materials science and engineering at the University of Wisconsin-Madison, and collaborators in Madison and at Yale University have made significant experimental strides in understanding how, when and where the constantly moving atoms in molten metal "lock" into place as the material transitions from liquid to solid glass.

Improved Capture of Cancer Cells in Blood Could Help Track Disease

University of Wisconsin-Madison

New research by University of Wisconsin-Madison Professor of Pharmacy Seungpyo Hong and his collaborators builds on several years of work in isolating circulating tumor cells, or CTCs, by demonstrating improved methods for their capture on clinical samples for the first time.

Reviewers of NIH Grants Cannot Distinguish the Good From the Great, Study Shows

University of Wisconsin-Madison

The National Institutes of Health (NIH) invested more than $27 billion in biomedical research through competitive grants during its 2017 fiscal year. Those grants were awarded based on scores assigned by, and conversation between, expert peer reviewers. This peer review process is a bedrock feature of doling out dollars for scientific projects with careful deliberation. But new findings by University of Wisconsin-Madison researchers suggest that reviewers are unable to differentiate the great proposals from the merely good ones.

They Grin, You Bear It. Research Reveals Physical Impact of a Smile

University of Wisconsin-Madison

Research led by Jared Martin, a psychology graduate student at the University of Wisconsin–Madison, shows that smiles meant to convey dominance are associated with a physical reaction — a spike in stress hormones — in their targets. On the other hand, smiles intended as a reward, to reinforce behavior, appear to physically buffer recipients against stress.

Freely Shared Satellite Data Improves Weather Forecasting

University of Wisconsin-Madison

For decades, the world meteorological satellite community has operated under a policy of freely shared data. It represents a philosophy and model of cooperation first promoted by the United States and adopted by global satellite agencies, which endure regardless of political or national persuasion. It's also a legacy and philosophy with roots that trace back decades to the University of Wisconsin-Madison Space Science and Engineering Center and the Cooperative Institute for Meteorological Satellite Studies.
