Ten current and former University of Chicago Physical Science Division scientists were named in Web of Science's 2019 report of highly cited researchers. Researchers on the list have demonstrated significant and broad influence in the past decade, with highly cited papers ranking in the top 1% by citation for a chosen field or fields.


UChicago scientist appointed FCC Chief Technology Officer

December 20, 2019

The Federal Communications Commission Chairman announced the appointment of UChicago's Monisha Ghosh to serve as the agency's Chief Technology Officer. Ghosh is a research professor in PME and an associate member of computer science. She has also been serving as a rotating program director at the National Science Foundation since September 2017, in the Computer and Network System Division within the Directorate of Computer and Information Science and Engineering. Ghosh will be the FCC's first female CTO.


Why some planets eat their own skies

Artists' impression of an exoplanet smaller than Neptune

In a paper published Dec. 17 in Astrophysical Journal Letters, Asst. Prof. Edwin Kite and colleagues at Washington University, Stanford University, and Penn State University offer an innovative explanation for why there are proportionally fewer Neptune-sized exoplanets: The oceans of magma on the surface of these planets readily absorb their atmospheres once planets reach about three times the size of Earth. 


Physicist taps quantum mechanics to crack molecular secrets

Giulia Galli, Liew Family Professor of Molecular Engineering and professor of chemistry, uses computational models to figure out the behavior of molecules and materials. The focus of Galli’s studies is to understand and predict how to harness molecular behavior to improve technology, particularly in the areas of purifying water, speeding up computation and sensing with quantum technology, and perfecting renewable energy technology. 
 


Parker Solar Probe’s first discoveries: odd phenomena in space weather, solar wind 

December 4, 2019

In four papers published Dec. 4 in Nature, researchers describe a flood of new data from the Parker Solar Probe's landmark mission that will help us understand everything from the nature of stars to improving our forecasting of solar storms that can affect electronics on Earth.  In its first year, the Parker Solar Probe learned new information about two types of major space weather events. It also saw the first signs of the zone around the sun where cosmic dust disappears—predicted decades ago, but never seen—as well as an entirely new phenomenon: bizarre “switchbacks” in the solar wind that flows off the surface of the sun.  


Astronomers propose a novel method of finding atmospheres on rocky worlds

In a series of four papers in the Astrophysical Journal, a team of astronomers, including Assoc. Prof. Jacob Bean, proposes a new method of using NASA's James Webb Space Telescope to determine whether a rocky exoplanet has an atmosphere. The technique, which involves measuring the planet’s temperature as it passes behind its star and then comes back into view, is significantly faster than more traditional methods of atmospheric detection like transmission spectroscopy.  


Chemists invent innovative way to create commonly used molecules called olefins

UChicago chemists have discovered an efficient method to make tetra-substituted olefins, a kind of olefin with four different attachments—used in everything from medicines to new ways to store data. With the new method, they can easily and precisely select the four different attachments. Additionally, their catalyst cuts the number of steps to make the compounds from around seven to two or three.

Quanta Magazine highlights three physicists--Stephen Parke of Fermi National Accelerator Laboratory, Xining Zhang of the University of Chicago and Peter Denton of Brookhaven National Laboratory—who discovered a new mathematical formula while studying neutrinos. 


How hackers could use Wi-Fi to track you inside your home

November 15, 2019

Illustration that shows how inexpensive devices can turn Wi-Fi signals into motion detectors.Illustration contains two sections, Near and Far. Both sections contain an anchor (WiFi Anchor), an individual, a couch, and a sniffer.

A new study from University of Chicago and University of California, Santa Barbara researchers finds that external attackers can use inexpensive technology to turn Wi-Fi signals into motion detectors, monitoring activity inside a building without being detected themselves. 

 With only a small, commercially available Wi-Fi receiver, an attacker from outside the target site can measure the strength of signals emitted from connected devices and monitor a site remotely for motion, sensing whether a room is occupied. The research, led by leading UChicago computer scientists Heather Zheng and Ben Zhao, reveals the technique of these attacks as well as potential defenses. 


​Mathematician named Fellow of the AMS

November 5, 2019

Lek-Heng Lim, Associate Professor in the Department of Statistics, has been named a Fellow of the American Mathematical Society (AMS) for "contributions to applied mathematics, particularly numerical linear algebra." The Fellows of the AMS designation recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics. 


​Theorists discover the ‘Rosetta Stone’ for neutrino physics

Three physicists at the University of Chicago and two national laboratories have discovered a fundamental identity in linear algebra—based on studying particle physics. 


​Astronomers use giant galaxy cluster as X-ray magnifying lens

Astronomers at the University of Chicago, MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, high-energy stages of star formation


Alternate reality game to encourage students to think critically about climate change

October 10, 2019

UChicago faculty designed an alternate reality game, Terrarium, to help students develop innovative proposals about climate change and practice the kind of rigorous inquiry at the heart of UChicago's core values.  


​Researchers develop blood tests to detect diabetic complications and cancer

University of Chicago Prof. Chuan He partnered with Northwestern Assoc. Prof. Wei Zhang to develop a simple blood test that accurately detects whether patients with diabetes have developed vascular complications, which are responsible for about two-thirds of diabetes deaths. 


​Nearly a decade in the making, exoplanet-hunting instrument installed in Hawaii

Jacob Bean, associate professor of astronomy and astrophysics at the University of Chicago, led a project to build and install an innovative instrument that will scan the skies for new exoplanets—worlds in other solar systems that could potentially host life. Over the past eight years, Bean and his team had designed and built the instrument, called MAROON-X; this summer they finally attached it to a telescope at the Gemini Observatory at the top of Mauna Kea, Hawaii.
