Swine Flu Crusaders

Kelly Broussard (left) and Sami Miller in the lab in Brownsville. When Sami Miller and Kelly Broussard decided to head down to the border last summer, they didn’t expect to end up in the middle of the global swine flu pandemic. As participants in the college’s Public Health Internship Program, they knew they’d be spending the summer at the Bro...

Where’s the Love?

Rival colonies of bacteria—even siblings—produce a lethal protein as they grow that can keep competitors at bay, scientists have found.

Scientists Find More Influences on Inherited Traits

Researchers have looked deeper into the makeup of DNA to get clues about why people might have different colors of hair or eyes, why some are taller or heavier and why some are more susceptible to certain diseases.

A Swarm of Salmonella

Dr. Rasika Harshey The same kind of evolutionary mechanism that explains why people tend to cross an intersection in an orderly fashion, or why a flock of birds can turn in the air with such balletic grace, may help explain why Salmonella bacteria are able to swarm together to better resist antibiotics. That’s one of the implications of a new ...

Better Drugs to Fight Flu is Goal of $1.5 Million NIH Project

University of Texas at Austin and Rice University scientists have won a $1.5 million grant from the National Institutes of Health to scrutinize the influenza A virus for clues that could lead to more effective antiviral drugs.

Making smart materials

Jason Shear, Marvin Whiteley and others are developing "smart materials" in order to study antibiotic resistance, develop new medical devices and explore how 3-D hydrogels can help regrow nerve cells.

Undergraduate Wang Wins $20,000 Mitchell Prize

Yuxuan Wang, a senior majoring in biochemistry, has won the $20,000 grand prize in the 10th annual University Co-op George H. Mitchell Awards for Academic Excellence for undergraduate students at The University of Texas at Austin.

Synthesizing the Natural

Dionicio Siegel, assistant professor of chemistry, looks to nature for scientific inspiration. For Dionicio Siegel to synthesize compounds in the lab that may someday help treat neurodegenerative diseases like Alzheimer’s, he has to rely on the work of a specialized class of people. Their job, essentially, is to go mucking around in the woods. “T...Dionicio Siegel, assistant professor of chemistry, looks to nature for scientific inspiration.

Oral Fixations

Graduate student Matthew Ramsey is working with Dr. Marvin Whiteley to better understand the complex ecologies of bacteria living in the human mouth. When microbiologist Marvin Whiteley and graduate student Matthew Ramsey began peering into the human mouth, as part of an ongoing quest to understand more about the ways that bacteria form complex ec...Graduate student Matthew Ramsey is working with Dr. Marvin Whiteley to better understand the complex ecologies of bacteria living in the human mouth.

Biologist Studies Evolution of HIV

AUSTIN, Texas--Dr. Sara Sawyer, an evolutionary biologist, will use a $120,000 grant from the Foundation for AIDS Research (amFAR) to study how the HIV virus and the cells it attacks have evolved together over time. The goal of her research is to discover new targets for drugs. When HIV infiltrates cells, the virus hijacks its host's genetic m...

The Bacteria Diet

How Pseudomonas proves so tenacious, and why it acts so differently in Cystic fibrosis-afflicted lungs than in normal human lungs, are puzzles that Whiteley has been working to solve for more than a decade.

Why Hybrids Grow Bigger

Why Hybrids Grow Bigger

AUSTIN, Texas—Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature. Their research has relevance in many areas of agriculture, a...
