Prof. Young-Kee Kim leads conference for aspiring female scientists
On a mid-January Friday night, Savannah Thais stood at the podium in International House’s Assembly Hall and shared some of her experiences as a female student in physics. She described the refusal of some male students to work with her, the difficulty in finding a female professor or mentor in math or physics, and the common message from adults that “I can’t be ‘girly’ and good at physics.”(more…)
Although the time and cost of sequencing an entire human genome has plummeted, analyzing the resulting genetic information— three billion base pairs from a single genome—can take many months.
In the journal Bioinformatics, however, a University of Chicago-based team—working with Beagle, one of the world’s fastest supercomputers devoted to life sciences—reports that genome analysis can be radically accelerated. This computer, based at Argonne National Laboratory, is able to analyze 240 full genomes in about two days. (more…)
A region deep inside the brain controls how quickly people make decisions about love, according to new research at the University of Chicago.
The finding, made in an examination of a 48-year-old man who suffered a stroke, provides the first causal clinical evidence that an area of the brain called the anterior insula “plays an instrumental role in love,” said UChicago neuroscientist Stephanie Cacioppo, lead author of the study. (more…)
Researchers had known for several decades that a certain chemical modification exists on messenger ribonucleic acid (mRNA), which is essential to the flow of genetic information. But only recently did experiments at the University of Chicago show that one major function of this modification governs the longevity and decay of RNA, a process critical to the development of healthy cells.
The chemical modification on mRNA in question is called N6-methyladenosine (m6A). A recent study by UChicago scientists reveals how the m6A modification on mRNA could affect the half-life of mRNA that in turn regulates cellular protein quantities. That discovery could provide fundamental insights into healthy functioning and disorders such as obesity, diabetes and infertility. (more…)
Massive terrestrial planets, called “super-Earths,” are known to be common in Earth’s galaxy, the Milky Way. Now a Northwestern University astrophysicist and a University of Chicago geophysicist report the odds of these planets having an Earth-like climate are much greater than previously thought.
Nicolas B. Cowan and Dorian Abbot’s new model challenges the conventional wisdom, which says super-Earths actually would be very unlike Earth—each would be a waterworld, with its surface completely covered in water. They conclude that most tectonically active super-Earths—regardless of mass—store most of their water in the mantle and will have both oceans and exposed continents, enabling a stable climate such as Earth’s.

The robot gripper invented by researchers at the University of Chicago and Cornell University is now available commercially. Empire Robotics, the company founded to commercialize the invention, is taking orders for the limited first release of its product called VERSABALL, scheduled to ship later this month.
“When we first started with the universal jamming gripper we did not think about industrial applications,” saidHeinrich Jaeger, the William J. Friedman and Alica Townsend Professor in Physics at the University of Chicago. “But soon there were inquiries from various companies and in those early days we had to tell them that we are in basic research rather than R&D and that therefore we could not really make robotic grippers for sale.” (more…)
ANN ARBOR — Like salmon in reverse, long-snouted Bandringa sharks migrated downstream from freshwater swamps to a tropical coastline to spawn 310 million years ago, leaving behind fossil evidence of one of the earliest known shark nurseries.
That’s the surprising conclusion of University of Michigan paleontologist Lauren Sallan and a University of Chicago colleague, who reanalyzed all known specimens of Bandringa, a bottom-feeding predator that lived in an ancient river delta system that spanned what is today the Upper Midwest. (more…)
Weather forecasters on exoplanet GJ 1214b would have an easy job. Today’s forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds.
That’s the implication of a study led by researchers in the Department of Astronomy and Astrophysics at the University of Chicago who have definitively characterized the atmosphere of a super-Earth class planet orbiting another star for the first time. (more…)
