Remembering High-Energy Physicist Roy Schwitters

Roy Schwitters, a world-renowned experimental high-energy physicist and emeritus professor at The University of Texas at Austin, passed away earlier this month.

Inspired by Biology, Physicists Make More Efficient Motors

Inspired by Biology, Physicists Make More Efficient Motors

Physicists at The University of Texas at Austin have discovered that mimicking human muscles can lead to more efficiently designed electric motors for use in robots and appliances. Their bioinspired motors use up to 22% less energy, have a greater range of motion and can lift objects higher than typical electric motors.

Department of Energy Selects Timothy Liao for Graduate Student Research Program

Timothy Liao, a physics Ph.D. student from The University of Texas at Austin, was recently selected to participate in the Department of Energy's (DOE) Office of Science Graduate Student Research (SCGSR) program along with 43 others. Liao will conduct part of his thesis research at Ames National Laboratory where he will develop computational tools for material design and discovery.

Mini Robots Reveal Links Between Bird Flocks and General Relativity

Mini Robots Reveal Links Between Bird Flocks and General Relativity

When self-propelling objects or living things interact with each other, interesting phenomena can occur. Birds align with each other when they flock together. People at a concert spontaneously create vortices when they nudge and bump into each other. Fire ants work together to create rafts that float on the water's surface.

Steven Weinberg’s Test of Quantum Mechanics Might Soon Be Realized

Steven Weinberg’s Test of Quantum Mechanics Might Soon Be Realized

About six years ago, Mark Raizen got a phone call from his University of Texas at Austin colleague, the Nobel laureate Steven Weinberg.

"He had a lot of questions for me about atomic clocks," Raizen said. "He had this idea for testing quantum mechanics, and he asked me if I could come up with a realistic system to do it in."

The development of high-speed strobe-flash photography in the 1960s by the late MIT professor Harold "Doc" Edgerton allowed us to visualize events too fast for the eye — a bullet piercing an apple, or a droplet hitting a pool of milk.

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.

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.

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.

New Gravitational Wave Catalog Reveals Black Holes of ‘All Shapes and Sizes’

New Gravitational Wave Catalog Reveals Black Holes of ‘All Shapes and Sizes’

Today, an international scientific collaboration released the largest catalog ever of collisions involving black holes and neutron stars, raising the total to 90 events. The results suggest that intermediate-mass black holes are more common than scientists previously thought. The catalog also includes the second discovery of an intriguing object that seems too small to be a black hole, yet too large to be a neutron star.

Markert Recognized as a 2021 American Physical Society Fellow

The American Physical Society has selected Christina Markert, a professor of physics at The University of Texas at Austin, as a 2021 APS Fellow. Fellowships are awarded based on outstanding contributions to the field of physics, and are received by no more than one half of one percent of the society's members each year.

New Model Reveals How Chromosomes Get Packed Up

To scrunch a chromosome (green), a condensin molecule opens and closes like a pair of fingers (light blue) connected by a hinge (dark blue).

One of the most astounding feats of nature is happening right now in cells throughout your body: noodle-like molecules called chromosomes, which carry part of your genetic blueprints and are about two inches (5 centimeters) long when fully stretched out, get stuffed into the cell's nucleus, which is at least 5,000 times smaller, with plenty of room for a bunch of other chromosomes.

Graduating Senior Finds Passions in Exoplanets and Outreach

When Zoe de Beurs arrived at UT Austin, she wasn't sure of what she wanted to do. Now, at the end of her fifth year, she's graduating from the Dean's Scholars honors program as a physics, astronomy and math triple major with an African and African Diaspora Studies minor.
