Weight Loss Programs Tailored to a Person's Genome May Be Coming Soon

Some health experts predict that the next big advance in helping overweight people achieve a healthier weight will be to use an individual's genetic data to customize diets and physical activity plans, an approach known as "precision weight loss." A recent summary report on the genetics of weight loss, developed by some of the leading experts in this field, finds that the biggest challenge to realizing this dream is the need for better analytical tools for discovering the relationships between genetics, behavior and weight-related diseases

Testing General Relativity

Testing General Relativity

This is the third of a three-part series on general relativity.

The Theory of General Relativity—Einstein's century-old description of gravity—presented physicists with some pretty bizarre predictions. To test them, scientists from the University of Texas at Austin have traveled to the Sahara Desert to observe a rare eclipse, launched into Earth orbit the densest known object orbiting anywhere in the Solar System, and used computers to model ripples in space and time unleashed by the mergers of black holes.

A team from the University of Texas at Austin constructed a temporary telescope house from plywood and styrofoam in the Sahara Desert to observe the bending of starlight by the sun during a total solar eclipse in June 1973. Photo: Richard Matzner.
The Race for Dark Energy (Audio)

The Race for Dark Energy (Audio)

This is the second of a three-part series on general relativity.

Einstein's Theory of General Relativity, which describes how gravity works, turns 100 this month. The theory has successfully explained a lot of what we observe out in the universe; but there are signs that it's incomplete. In the 1990s, astronomers observed that the expansion of the universe is speeding up, as if some mysterious force is pushing everything apart faster and faster. Nearly 20 years later, one of the biggest unanswered questions in science is: what is this dark energy? Not only was dark energy not predicted by general relativity, but its mere existence might mean that the theory needs to be tweaked or even replaced.

Can General Relativity, at 100, Withstand Some Holes?

Can General Relativity, at 100, Withstand Some Holes?

This is the first of a three-part series on general relativity. 

In November 1915, Albert Einstein stood before his colleagues in the Prussian Academy of Sciences and unveiled a set of equations that would forever change the way we see the universe. The Theory of General Relativity, Einstein's description of gravity, explained the motions of everything we see in the universe.

Giant Magellan Telescope, World’s Largest, Breaks Ground in Chilean Desert

Leaders and supporters from The University of Texas at Austin's McDonald Observatory, along with representatives from an international group of partner universities and research institutions, are gathering on a remote mountaintop high in the Chilean Andes today to celebrate groundbreaking for the Giant Magellan Telescope (GMT).

Researchers Develop New Tool for Green Chemistry

Researchers Develop New Tool for Green Chemistry

Chemists from The University of Texas at Austin and Texas State University have developed an environmentally friendly method for creating chemical structures with complex shapes like those found in living things. The results have implications for reducing toxic waste in chemical manufacturing and research, understanding basic biological processes and developing more effective medical therapies.

Promising New Target in War Against Flu

Promising New Target in War Against Flu

Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus, which causes flu, can overcome one of our body's natural defense mechanisms. That makes this flu protein a potentially good target for antiviral drugs directed against the flu virus

The Case of the Missing Folate (Audio)

The Case of the Missing Folate (Audio)

When Richard Finnell first met her, Rachel was a nine-year-old girl with severe developmental delays. Her condition seemed to be caused by a deficiency in a critical B vitamin called folate. Yet she had plenty of folate circulating in her blood. Somehow it was vanishing before it got to her brain and spine. Eventually Finnell made a surprising discovery. He's now using new genetic tools like CRISPR to better understand her condition and test possible therapies.

UT Austin Receives $4M to Develop Techniques for Brain Imaging and Manipulation

UT Austin Receives $4M to Develop Techniques for Brain Imaging and Manipulation

Researchers at The University of Texas at Austin will receive three grants totaling $4 million to develop techniques for imaging and manipulating the activity of neurons in the brain, research that will help scientists explore the mechanisms of addiction, obesity, fear and many other brain states and disorders. The funding, provided by the National Institutes of Health, is part of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative launched last year by President Barack Obama.
