In the Race of Life, Better an Adaptable Tortoise than a Fit Hare

When it comes to survival of the fittest, it’s sometimes better to be an adaptable tortoise than a fitness-oriented hare, researchers say.

Placing Landmarks on the Genome Map

Vishy Iyer and colleagues use the power of the Ranger supercomputer and next-gen sequencers to study role of heredity in gene transcription.

Plants ‘Remember’ Winter To Bloom In Spring With Help of Special Molecule

Many flowering plants bloom in bursts of color in spring after long periods of cold in the winter, and biologists have discovered how the plants know they've experienced the cold.

Scientists Reveal Criminal Virus Spreaders Using Evolutionary Forensics

The source of HIV infection in two separate criminal cases in which men were convicted of intentionally infecting their female sexual partners was confirmed by David Hillis and colleagues using evolutionary forensics.

With $2.4 Million Grant, Researchers To Decode Geranium’s Evolutionary Mysteries

With $2.4 Million Grant, Researchers To Decode Geranium’s Evolutionary Mysteries

Botany researcher Dr. Robert Jansen and his colleagues have received a four-year, $2.4 million grant from the Plant Genome Program to investigate the genomes of the geranium plant and 15 related species.

Improving Cotton the Goal of $3.8 Million Grant to Plant Geneticist

Jeff Chen will use next-generation DNA sequencing technologies to study the genomics of fiber production in cotton with a $3.8 million grant from the NSF.

Department of Energy Fellowship Provides Support for Grad Student

College of Natural Sciences graduate student Cory Nelson has received a fellowship as part of a new U.S. Department of Energy program.

Research of Cell Movements in Developing Frogs Reveals New Twists in Human Genetic Disease

Mutations in a gene known as “Fritz” may be responsible for causing human genetic disorders such as Bardet-Biedl syndrome, University of Texas at Austin developmental biologist John Wallingford and Duke University human geneticist and cell biologist Nicholas Katsanis have found.

Biologists Use Bacteria from Hot Springs to Reveal Clues To Evolution of Early Life and To Unlock Biofuels’ Potential

Biologists Use Bacteria from Hot Springs to Reveal Clues To Evolution of Early Life and To Unlock Biofuels’ Potential

A bacteria that lives in hot springs in Japan may help solve one of the mysteries of the early evolution of complex organisms, according to a study just published in PLoS Biology.

Foodie for Life

As a fourth-grader, Ryan Riddle asked his parents for a George Foreman Grill for Christmas. And that was only the beginning for Riddle, a Dean’s Scholars biochemistry major from Spring, TX. Before he got to middle school, Riddle was taking week-long cooking courses over the summer. He downloaded recipes from the internet and convinced his parents...

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 ...
