While watching the production of porous membranes used for DNA sorting and sequencing, University of Illinois researchers wondered how tiny steplike defects formed during fabrication could be used to improve molecule transport. They found that the defects – formed by overlapping layers of membrane – make a big difference in how molecules move along a membrane surface. Instead of trying to fix these flaws, the team set out to use them to help direct molecules into the membrane pores.

Their findings are published in the journal Nature Nanotechnology.

Nanopore membranes have generated interest in biomedical research because they help researchers investigate individual molecules – atom by atom – by pulling them through pores for physical and chemical characterization. This technology could ultimately lead to devices that can quickly sequence DNA, RNA or proteins for personalized medicine.

  • In Memoriam

We are saddened to report that John Robert Schrieffer, Nobel laureate and alumnus of the Department of Physics at the University of Illinois at Urbana-Champaign, passed away on July 27, 2019, in Tallahassee, Florida. He was 88 years old.

Schrieffer was the “S” in the famous BCS theory of superconductivity, one of the towering achievements of 20th century theoretical physics, which he co-developed with his Ph.D advisor Professor John Bardeen and postdoctoral colleague Dr. Leon N. Cooper. At the time that Schrieffer began working with Bardeen and Cooper, superconductivity was regarded as one of the major challenges in physics. Since the discovery of the hallmark feature of superconductivity in 1911—the zero resistance apparently experienced by a current in a metal at temperatures near absolute zero—a long list of famous theoretical physicists had attempted to understand the phenomenon, including Albert Einstein, Niels Bohr, Richard Feynman, Lev Landau, Felix Bloch, Werner Heisenberg and John Bardeen himself (who was awarded the Nobel Prize for his co-invention of the transistor at around the time that Schrieffer began working with him in 1956).

Physics Professor Julia “Jessie” Shelton of the University of Illinois at Urbana-Champaign has been awarded the 2013 Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the US government on scientists and engineers in the early stages of their independent research careers.

Shelton is a theorist whose work spans a broad range of topics in particle physics beyond the Standard Model. She is especially interested in elucidating the nature of dark matter and in searching for unusual footprints of new physics at the Large Hadron Collider (LHC) at CERN in Switzerland. Her recent work focuses on possible decays of the Higgs boson to new particles, strategies to detect particles produced at the LHC that travel macroscopic distances before decaying, and the cosmological origin stories of "hidden sector" dark matter, i.e., dark matter that interacts far more strongly with other dark particles than it does with us.

John Robert Schrieffer, one of three Americans who shared the Nobel Prize in physics for their theory explaining superconductivity, a near-miraculous process in which electric current flows without resistance, died July 27 at a nursing facility in Tallahassee. He was 88. Among physicists, the theory that accounted for the mysteries of superconductivity became known as the BCS theory, for its three creators: John Bardeen, Leon Neil Cooper and Dr. Schrieffer. They shared the Nobel in 1972. When the theory was developed in 1957, Dr. Schrieffer was working on his dissertation at the University of Illinois under Bardeen, who had received a Nobel Prize the previous year as an inventor of the transistor.

If he told you, he would have to kill you.

So Alan Nathan, the University of Illinois scholar who is the unofficial physicist of Major League Baseball, is keeping his lips sealed.

“There is a limit to what I can talk about,” said Nathan. “It will become public soon.”

 

What is so sensitive that discretion is required?

Nathan and a group of fellow academics, on assignment from MLB Commissioner Rod Manfred, are closing in on the cause of the home runs being hit out of MLB stadiums in record numbers.

Alumnus gift continues legacy of excellence at Illinois Physics

“We deeply appreciate Gary Kelly’s generosity and his investment in our department’s core missions of research, teaching, and outreach,” comments Head of Department and Professor Matthias Grosse Perdekamp. “Unrestricted funds such as these are applied where they will make the greatest impact. Through his generosity, Gary Kelly’s legacy at Illinois will include his support of important new opportunities directly in line with our core missions. A large portion of Gary’s gift will support the research of exceptional women faculty early in their careers, enabling Illinois Physics to attract and retain promising women physicists.”
