A group of University of Chicago scientists has uncovered a previously unknown way that our genes are made into reality. Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA itself modulates how DNA is transcribed—using a chemical process that is increasingly apparent to be vital to biology. The discovery has significant implications for our understanding of human disease and drug design.

A new planet roughly twice the size of Earth has been discovered located within the “habitable zone”—the range of distances from a star where liquid water may exist on the planet’s surface. A research team that included a UChicago graduate student confirmed the finding after volunteer citizens flagged a crucial piece of evidence in data from NASA’s Kepler spacecraft.
Researchers with NASA, the University of Chicago and the Potsdam Institute for Climate Impact Research found that by adding data on when each specific region plants and harvests its crops, they could double the accuracy of crop prediction. This could improve the information available for policymakers and markets to brace for the impacts of crop loss.
Scientists are creating a network in the Chicago area that taps the principles of quantum physics to send information. Such a link could one day form the basis for a truly secure network, which would have wide-ranging impact on communications, computing and national security. Stretching between Argonne and Fermi national laboratories, the connection will "teleport" information across 30 miles and is expected to be among the longest in the world to send secure information using quantum physics.
In a new paper published in Nature, three University of Chicago scientists estimate that given how quickly LIGO researchers saw the first neutron star collision, they could have a very accurate measurement of the rate of the expansion of the universe within five to ten years.

A team of University of Chicago scientists ran quantum simulations to develop a new model of the behavior of water at extremely high temperatures and pressures. The computational measurements, published June 18 in the Proceedings of the National Academy of Sciences, should help scientists understand water’s role in the makeup of the mantle and potentially in other planets.
Forward-thinking scientists in the 1970s suggested that circuits could be built using molecules instead of wires, and over the past decades that technology has become reality. The trouble is, some molecules have particularly complex interactions that make it hard to predict which of them might be good at serving as miniature circuits. But a new paper by two University of Chicago chemists presents an innovative method that cuts computational costs and improves accuracy by calculating interactions between pairs of electrons and extrapolating those to the rest of the molecule.
A study in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it’s exceeded, blockages form that are remarkably similar to traffic jams—and climate forecasters can use the same math to model them both.
Funded by a $1.6 million award from the National Science Foundation, the Institute for Molecular Engineering at the University of Chicago and Harvard University will head a new nationwide graduate student training program for quantum science and engineering.

Parker will receive the American Physical Society’s Medal for Exceptional Achievement in Research at a Feb. 1 ceremony in Washington, D.C. The medal citation notes Parker’s “fundamental contributions to space physics, plasma physics, solar physics and astrophysics for over 60 years.”
A particular set of chemical reactions governs many of the processes around us—everything from bridges corroding in water to your breakfast breaking down in your gut. One crucial part of that reaction involves electrons striking water, and despite how commonplace this reaction is, scientists still have to use ballpark numbers for certain parts of the equation when they use computers to model them.
A study offers a new and better set of numbers, which may help scientists and engineers create better ways to split water for hydrogen fuel and other chemical processes.
Researchers with the University of Chicago have published a concept to use a naturally occurring mineral called calcite to “grow” scales that can attach to soft materials. The setup could one day serve as waterproof implants to reinforce bones or joints.
Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall "functional" diversity--how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks. University of Chicago scientists documented this surprising trend in a study on extinctions published Jan. 5 in the Proceedings of the National Academy of Sciences.
Scientists with the University of Chicago have laid out a comprehensive theory for how our solar system could have formed in the wind-blown bubbles around a giant, long-dead star.
