New Phononic Crystal Might Enable Better Mobile Communications

New Phononic Crystal Might Enable Better Mobile Communications

Using a microwave microscope, UT Austin researchers visualized elastic waves as they travel right to left, following a Z-shaped boundary in a phononic crystal, without losing energy. The image is approximately 0.1 millimeters high. Credit: Keji Lai/University of Texas at Austin.

Experts have taken a step towards the use of special materials called phononic crystals in cell phones and other mobile devices, an advance that is important to make more devices compatible with emerging 5G communications and other new technologies.

Some of the same researchers at The University of Texas at Austin who created a key to all coronavirus vaccines used in the U.S. have made a similar advance against the human metapneumovirus (hMPV), one of a handful of remaining respiratory viruses for which there is currently no vaccine.

A Physicist’s Search for Beauty (Audio)

A Physicist’s Search for Beauty (Audio)

Here in part 2 of our continuing remembrance of Steven Weinberg, we're diving a little deeper into what we know because of him. Weinberg was one of the world's greatest theoretical physicists, and his passing last year was deeply felt not only by us here at The University of Texas at Austin, but by a broad community of scientists and science-loving people. Weinberg summed up the goal of his life's work as: "to know why things are the way they are." To him, that meant distilling the rules of physics down to their simplest, most beautiful essence.

Gene Editing Gets Safer Thanks to Redesigned Protein

Gene Editing Gets Safer Thanks to Redesigned Protein

UT Austin researchers were surprised to discover that when Cas9 encounters a mismatch in a certain part of the DNA (red and green), instead of giving up and moving on, it has a finger-like structure (cyan) that swoops in and holds on to the DNA, making it act as if it were the correct sequence.

One of the grand challenges with using CRISPR-based gene editing on humans is that the molecular machinery sometimes makes changes to the wrong section of a host's genome, creating the possibility that an attempt to repair a genetic mutation in one spot in the genome could accidentally create a dangerous new mutation in another.

A New Way to Disarm Antibiotic Resistance in Deadly Bacteria

A New Way to Disarm Antibiotic Resistance in Deadly Bacteria

An antibiotic resistant bacterium (Klebsiella pneumoniae) is treated solely with the last-resort antibiotic imipenem (left); and with a combination of imipenem and a DsbA inhibitor, causing it to rupture and die (right). Image credit: Nikol Kadeřábková.

Scientists think they may have uncovered a whole new approach to fighting antibiotic-resistant bacteria, which, if successful, would help address a health crisis responsible for more deaths every year than either AIDS or malaria.

Remembering Steven Weinberg (Audio)

Remembering Steven Weinberg (Audio)

Today, in the first of two parts of a special segment, we're remembering the life and legacy of one of the greatest theoretical physicists of all time — The University of Texas at Austin's Steven Weinberg, who died in July. We're exploring who he was as a scientist, writer and mentor — and a deep thinker about our place in the universe. We'll hear from colleagues who worked with him — fellow UT Austin physicists Katherine Freese, Willy Fischler and Can Kilic — and from his former student John Preskill.

Frog Pandemic (Audio)

Frog Pandemic (Audio)

Until COVID-19, few people alive today had experienced the chaos and destruction of a really bad pandemic, one that has at times ground businesses, schools and social lives to a near standstill and killed millions globally. But did you know that we aren't alone in being battered by a global infectious disease? Frogs are also struggling through their own pandemic that, according to biologist Kelly Zamudio, has several eerie parallels with COVID-19. Perhaps our own encounters with a pandemic will give us new sympathy for our slimy, bug-eyed friends.

Getting Math and Physics on the Same Page

Getting Math and Physics on the Same Page

In this illustration, three exotic particles called “anyons” circle around each other in a process called braiding. Mathematicians use a method called generalized symmetry to study such interactions.

When physicists want to explain how subatomic particles—such as electrons, photons, quarks and neutrinos—behave and interact, they use a framework called quantum field theory (QFT). QFT might be the most successful physical theory ever invented. It was used to predict the existence of the Higgs boson, antimatter and neutrinos. And it has predicted the results of particle physics experiments accurately to the highest number of decimal places ever recorded.

Sodium-based Material Yields Stable Alternative to Lithium-ion Batteries

Sodium-based Material Yields Stable Alternative to Lithium-ion Batteries

Scientists at the University of Texas at Austin have developed a new sodium metal anode for rechargeable batteries (left) that resists the formation of dendrites, a common problem with standard sodium metal anodes (right) that can lead to shorting and fires. Images were taken with a scanning electron microscope. Image credit: Yixian Wang/University of Texas at Austin.

University of Texas at Austin researchers have created a new sodium-based battery material that is highly stable, capable of recharging as quickly as a traditional lithium-ion battery and able to pave the way toward delivering more energy than current battery technologies.
