Texas Invasive Species Program Gets Boost from Lee and Ramona Bass Foundation

With a new $6M grant from the Lee and Ramona Bass Foundation, researchers in the Texas Invasive Species Program will combat exotic pests that threaten Texas. In this photo, key collaborator Dino Martins (center), director of Mpala Research Center, shows Rob Plowes (left) and Larry Gilbert (right) some buffelgrass—an invasive in Texas—in its Kenyan home range.

Destructive and costly fire ants, crazy ants, moth larvae and invasive grasses can wreak havoc on Texas ecosystems, but biologists at The University of Texas at Austin are bringing the fight to them. With the help of a $6 million continuing grant from the Lee and Ramona Bass Foundation, researchers in the Texas Invasive Species Program will seek new, sustainable approaches to counter exotic pests that threaten Texas.

New Material Holds Promise for More Secure Computing

New Material Holds Promise for More Secure Computing

When the two atomically-thin sheets of this new material are rotated slightly with respect to each other, an interference pattern known as a moiré pattern appears. This feature appears to enable Li’s new material to act as a series of single photon emitters. Credit: University of Texas at Austin.

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.

Scientists Synthesize a New Type of DNA with Extra Building Blocks

Scientists Synthesize a New Type of DNA with Extra Building Blocks

A DNA double helix built from eight hachimoji building blocks: G (green), A (red), C (dark blue), T (yellow), B (cyan), S (pink), P (purple) and Z (orange). The first four building blocks are found in human DNA; the last four are synthetic. Each strand of the double helix has the sequence CTTAPCBTASGZTAAG.

A team of synthetic biologists led by Steven Benner at the Foundation for Applied Molecular Evolution—and including Andy Ellington at The University of Texas at Austin—have synthesized a new kind of DNA that uses eight building blocks instead of the four found in all earthly life. Reporting today in the journal Science, the researchers suggest the new eight-letter DNA could find applications in medicine and biological computing. The finding also has implications for how scientists think about life elsewhere in the universe.

Interacting With More People is Shown to Keep Older Adults More Active

Interacting With More People is Shown to Keep Older Adults More Active

It's been said that variety is the spice of life, and now scientists say variety in your social circle may help you live longer. Researchers at The University of Texas at Austin have found that older adults who spend more time interacting with a wide range of people were more likely to be physically active and had greater emotional well-being.

A new astronomical spectrograph provides the highest precision measurements to date of infrared signals from nearby stars, allowing astronomers to detect planets capable of having liquid water on their surfaces that orbit cool stars outside our solar system. The Habitable Zone Planet Finder (HPF) allows precise measurement of a star's radial velocity, measured by the subtle change in the color of the star's spectra as it is tugged by an orbiting planet, which is critical information in the discovery and confirmation of new planets.

Before she was winning awards at UT Austin, computer science sophomore Chineye Emeghara was teaching herself to code in high school with resources she discovered online. Later, on a trip to Nigeria, where her mother lived before immigrating to the U.S., she realized that she could apply her interest in technology to improve the lives of others.
