Which Mental Superpower Would You Choose? (Audio)

What if people who lost a particular brain function—say, an Alzheimer's patient who can no longer make new memories—had the same option as many people who've lost limbs or other body parts—the chance to use technology to supplement what's no longer there? Or what if you could boost a healthy person's brain, essentially giving them mental superpowers, like the ability to become a Kung Fu master by downloading new skills directly to your brain?

Scientists Pinpoint New Alcohol Addiction Pathway in Brain

Scientists Pinpoint New Alcohol Addiction Pathway in Brain

There's a new line of attack in the war on alcoholism: Reporting in the journal Science, UT Austin researchers discovered that people suffering from alcoholism have less of a protein, GAT-3, in the part of the brain called the amygdala.

In the same way that barcodes on your groceries help stores know what's in your cart, DNA barcodes help biologists attach genetic labels to biological molecules to do their own tracking during research, including of how a cancerous tumor evolves, how organs develop or which drug candidates actually work. Unfortunately with current methods, many DNA barcodes have a reliability problem much worse than your corner grocer's. They contain errors about 10 percent of the time, making interpreting data tricky and limiting the kinds of experiments that can be reliably done.

By altering the genetic code in bacteria, researchers at The University of Texas at Austin have demonstrated a method to make therapeutic proteins more stable, an advance that would improve the drugs' effectiveness and convenience, leading to smaller and less frequent doses of medicine, lower health care costs and fewer side effects for patients with cancer and other diseases.

For decades, Michael Mauk, a neuroscientist at the University of Texas at Austin, has been developing a computer simulation of the part of our brains called the cerebellum that directs many of the movements we make often, yet don't have to think about, like walking or picking up a glass of water.

A Look at How A.I. is Helping the Human Race

A Look at How A.I. is Helping the Human Race

Artificial intelligence is quickly creeping into our lives, from smart phone apps that help us find the quickest path through rush hour traffic to voice assistants that serve up lasagna recipes on command. In their new book AIQ: How People and Machines Are Smarter Together, James Scott and Nick Polson lay out an optimistic vision for how AI can help us overcome our cognitive weaknesses and live happier, healthier lives. The book is already attracting attention from media outlets including the Wall Street Journal, The Times (UK) and PBS's SciTechNow.

James Allison Eases Off the Brakes (Audio)

Forty years ago, when James Allison had just gotten his PhD in biochemistry, he was intrigued by this far-out idea that was floating around about a new way to treat cancer. The idea—dubbed cancer immunotherapy—was to train the body's immune system to attack cancer cells—the same way this system already goes after bacteria and viruses. He was one of the few people who actually believed it could work.

UT Austin Mourns Passing of George Sudarshan, Titan of 20th Century Physics

World-renowned physicist E.C. George Sudarshan died of natural causes this week at the age of 86. A professor of physics at The University of Texas at Austin from 1969 to 2016, he made many important contributions to theoretical physics. Ennackal Chandy George Sudarshan was born in Kottayam, Kerala, India on Sep. 16, 1931. He received his Ph.D. de...

Scientists at The University of Texas at Austin have successfully tested in animals a drug that, they say, may one day help block the withdrawal symptoms and cravings that incessantly coax people with alcoholism to drink. If eventually brought to market, it could help the more than 15 million Americans, and many more around the world who suffer from alcoholism stay sober.
