An elite prize among scientists worldwide is being given to Steven Weinberg, a professor of physics at The University of Texas at Austin, for his "continuous leadership in fundamental physics, with broad impact across particle physics, gravity and cosmology, and for communicating science to a wider audience."

Allan MacDonald, a professor of physics at The University of Texas at Austin, has received the 2020 Wolf Prize in Physics for his groundbreaking work in a field known as twistronics, which holds extraordinary promise to "lead to an energy revolution," according to the Wolf Foundation announcement today.

The American Association for the Advancement of Science, the world's largest general scientific society, has named Mark Raizen, a professor in the Department of Physics, a 2019 AAAS Fellow.

If you wanted to deliver a package across the street and avoid being hit by a car, you could program a powerful computer to do it, equipped with sensors and hardware capable of running multiple differential equations to track the movement and speed of each car. But a young child would be capable of doing the same task with little effort, says Alex Demkov, professor of physics at The University of Texas at Austin.

Biofilms – tightly packed sticky blobs of many bacteria – are a huge problem in the medical world. Biofilms can form on joint replacements and medical equipment, they cause long-term infections in lungs and urinary tracts, and, according to Centers for Disease Control estimates, are responsible for 1.7 million infections in U.S. hospitals every year – and 99,000 deaths.

Last year, scientists demonstrated that twisted bilayer graphene — a material made of two atom-thin sheets of carbon with a slight twist — can exhibit alternating superconducting and insulating regions. Now, a new study in the journal Nature by scientists from Spain, the U.S., China and Japan shows that superconductivity can be turned on or off with a small voltage change, increasing its usefulness for electronic devices.

Feliciano Giustino recently joined the University of Texas at Austin faculty in the Department of Physics and is a Moncrief Chair in the Oden Institute for Computational Engineering and Sciences, where he will direct the Center for Quantum Materials Engineering. He was previously a professor in the Department of Materials at Oxford University.

This summer the Department of Physics welcomed an astrophysicist whom Global Citizen put on a list of the "17 Top Female Scientists who have Changed the World," alongside names like Jane Goodall and Marie Curie.

As computers advance, encryption methods currently used to keep everything from financial transactions to military secrets secure might soon be useless, technology experts warn. Reporting today in the journal Nature, a team of physicists and engineers led by University of Texas at Austin physics professor Xiaoqin Elaine Li report they have created a material with light-emitting properties that might enable hack-proof communications, guaranteed by the laws of quantum mechanics.

Over the past few decades, the cost of storing data on hard disk drives (HDDs) has fallen dramatically, enabling revolutions in personal, scientific and cloud computing and allowing for storage of ever-greater amounts of data. But even as data collection continues to skyrocket, the cost-per-bit trend has been flattening out, leading to calls for new innovations in technology.

The scientists looking for gravitational waves report that last year they observed four additional ripples in space-time. During about a nine-month period, scientists involved with the National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) collaboration and the European-based Virgo gravitational-wave detector encountered eight gravitational waves—twice as many as previously reported—including a newly identified binary black hole that was the most precisely located in the sky to date.

The University of Texas at Austin will be a key player in LaserNetUS, a new national network of institutions operating high-intensity, ultrafast lasers. The overall project, funded over two years with $6.8 million from the U.S. Department of Energy's Office of Fusion Energy Sciences, aims to help boost the country's global competitiveness in high-intensity laser research.

The ATLAS Collaboration, an international team of physicists including Peter Onyisi from the University of Texas at Austin, has announced the observation of Higgs bosons produced together with a top-quark pair. Observing this extremely rare process is a significant milestone for the field of high-energy physics.

Scientists have recently discovered a method in cancer's madness. Before now, they've been perplexed by how cancer cells, growing alongside healthy cells, often spread much faster into surrounding tissue than randomness would dictate. It's as if cancerous cells are intentionally moving directly outward, invading healthy tissue.
