With the turning of a shovelful of earth a mile underground, a new era in international particle physics research officially begins.

Physicists have been puzzled ever since an experiment at Brookhaven National Laboratory in the late 1990s found that muons, elementary particles produced when cosmic rays hit our atmosphere, have slightly different magnetic properties than predicted. If true, it could mean a shakeup is in store for the theoretical framework that physicists use to describe the universe.

Microbial biofilms—dense, sticky mats of bacteria that are hard to treat and can lead to dangerous infections—often form in medical equipment, such as flexible plastic tubing used in catheters or in tubes used to help patients breathe. By some estimates, more than 1 million people contract infections from medical devices in U.S. hospitals each year, many of which are due to biofilms. A study from The University of Texas at Austin suggests a possible new way to prevent such biofilms from forming, which would sharply reduce incidents of related hospital-borne infection.

The University of Texas at Austin mourns the loss of renowned physicist and professor emerita Cécile DeWitt-Morette, who was a faculty member in the Department of Astronomy and the Department of Physics. DeWitt-Morette received international acclaim for her work in theoretical physics and for the educational institution she established in Europe, L'École de Physique des Houches, which helped launch many of the world's leading physicists and mathematicians.

A research team led by physics professor Keji Lai at the University of Texas at Austin has discovered that a material he studies has an unusual property that could one day lead to cell phones and other electronic devices that are smaller, lighter and more energy efficient.

Mark Raizen, a professor of physics at The University of Texas at Austin, and his team have developed the world's highest resolution atom lens, a key component of a new kind of microscope called an atom microscope, which can image the surface of a material at the atomic scale and reveal its chemical composition.

Salt, snowflakes and diamonds are all crystals, meaning their atoms are arranged in 3-D patterns that repeat. Today scientists are reporting in the journal Nature on the creation of a phase of matter, dubbed a time crystal, in which atoms move in a pattern that repeats in time rather than in space.

Researchers at The University of Texas at Austin have designed ultra-flexible, nanoelectronic thread (NET) brain probes that can achieve more reliable long-term neural recording than existing probes and don't elicit scar formation when implanted. The researchers described their findings in a research article published on Feb. 15 in Science Advances.

People with cystic fibrosis, diabetes, and chronic obstructive pulmonary disease often develop serious and even life-threatening bacterial infections that are hard to treat, in large part because the bacteria form dense clusters called biofilms. Biofilms are resistant to the host's immune cells and to antibiotics.

Two amazing scientific discoveries, both with ties to the College of Natural Sciences at The University of Texas at Austin, were named the top 2 science stories of 2016 by Discover Magazine. Other major media outlets also included them in their year-end "best of" lists, including National Geographic, Science News, Science and the New York Times. A third story from the College of Liberal Arts and Jackson School of Geosciences, which solved the mystery of how the most famous human ancestor died, appears in Discover's top ten as well.

Three scientists at The University of Texas at Austin have been elected as fellows of the American Physical Society for their outstanding contributions and leadership in physics. The new fellows are: physicists Greg Fiete and Karol Lang, both in the College of Natural Sciences; and electrical engineer Emanuel Tutuc, in the Cockrell School of Engineering.

Physicists have hypothesized the existence of fundamental particles called sterile neutrinos for decades and a couple of experiments have even caught possible hints of them. However, according to new results from two major international consortia, the chances that these indications were right and that these particles actually exist are now much slimmer.
