Mutation Stops Worms From Getting Drunk

Mutation Stops Worms From Getting Drunk

drunk-sober-worms-humans.jpgNeuroscientists at The University of Texas at Austin have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal.

Novel Method for Isotope Enrichment

Novel Method for Isotope Enrichment

Mark Raizen and his colleagues have developed a new method for enriching stable isotopes, a group of the world’s most expensive chemical commodities which are vital to medical imaging and nuclear power. The work has attracted some attention from the science and medical world.

Researchers Discover Why It's So Hard to Grow an Extra Finger

Researchers Discover Why It's So Hard to Grow an Extra Finger

The fact that most humans have five digits on each hand and foot is due in part to a complex developmental pathway called Hedgehog. If something goes wrong in this process during development, say a mutation in a critical gene that affects its expression, a person might be born with extra fingers or toes, a condition known as polydactyly. New research shows that for at least one part of the pathway, there is a sort of failsafe mechanism that seems to make it harder for mistakes to happen.

Improved Method for Isotope Enrichment Could Secure a Vital Global Commodity

Improved Method for Isotope Enrichment Could Secure a Vital Global Commodity

Researchers at The University of Texas at Austin have devised a new method for enriching a group of the world’s most expensive chemical commodities, stable isotopes, which are vital to medical imaging and nuclear power, as reported this week in the journal Nature Physics.

Variety in Diet Can Hamper Microbial Diversity in the Gut

Variety in Diet Can Hamper Microbial Diversity in the Gut

Scientists from The University of Texas at Austin and five other institutions have discovered that the more diverse the diet of a fish, the less diverse are the microbes living in its gut. If the effect is confirmed in humans, it could mean that the combinations of foods people eat can influence the diversity of their gut microbes.

Researchers Discover Possible New Target to Attack Flu Virus

Researchers Discover Possible New Target to Attack Flu Virus

Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.

The Horn: Junk Food, Good Science

The Horn: Junk Food, Good Science

Think you’ll always pick chocolate over a bag of chips? Don’t be so sure. Researchers have found that if they can get people to pay more attention to a particular type of junk food, they will begin to prefer it—even weeks or months after the experiment. The finding suggests a new way to manipulate our decisions and perhaps even encourage us to pick...
Possible Explanation for Human Diseases Caused by Defective Ribosomes

Possible Explanation for Human Diseases Caused by Defective Ribosomes

Ribosomes are essential for life, generating all of the proteins required for cells to grow. Mutations in some of the proteins that make ribosomes cause disorders characterized by bone marrow failure and anemia early in life, followed by elevated cancer risk in middle age. These disorders are generally called “ribosomopathies.”

Neurobiologist Studies His Own Brain

Neurobiologist Studies His Own Brain

Dr. Russell Poldrack, professor of neurobiology and psychology, discusses his findings of a 14 month study he conducted on his own brain."We are particularly interested in how communication between different parts of my brain changes in relation to psychological factors such as stress or mood, and how it relates to biological factors that will...
Brain Scans Show We Take Risks Because We Can't Stop Ourselves

Brain Scans Show We Take Risks Because We Can't Stop Ourselves

A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it's probably not because their brains' desire systems are too active, but because their self-control systems are not active enough.
