Gene Discovery Made Easier

Gene Discovery Made Easier

AUSTIN, Texas—The identification of disease-causing genes will be much easier and faster using a powerful new gene-networking model developed by researchers at The University of Texas at Austin. Edward Marcotte and his colleague, postdoctoral researcher Insuk Lee, used the gene network technique to identify new genes that regulate life span and ar...

Scientists Find Missing Evolutionary Link Using Tiny Fungus Crystal

The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex.

When She's Turned On, Some Of Her Genes Turn Off

AUSTIN, Texas—When a female is attracted to a male, entire suites of genes in her brain turn on and off, show biologists from The University of Texas at Austin studying swordtail fish. Molly Cummings and Hans Hofmann found that some genes were turned on when females found a male attractive, but a larger number of genes were turned off. “When fema...

Tree of Life Revealed for Flowering Plants

AUSTIN, Texas—The evolutionary Tree of Life for flowering plants has been revealed using the largest collection of genomic data of these plants to date, report scientists from The University of Texas at Austin and University of Florida. The scientists, publishing two papers in Proceedings of the National Academy of Sciences this week online, found...

Higher Brain Damage in Alcoholics with Cirrhosis of the Liver

AUSTIN, Texas—An examination of gene expression in the frontal cortex has found that brain function is even more impaired in alcoholics with cirrhosis of the liver, one of the most common and serious medical complications linked to alcoholism. Sustained exposure to alcohol can cause scarring and dysfunction of the liver, referred to as cirrhosis. ...

Fire ant lab celebrates 20 years of research

AUSTIN, Texas—The red imported fire ant laboratory at The University of Texas at Austin Brackenridge Field Lab (BFL) is celebrating 20 years of research this month. Dr. Larry Gilbert, director of BFL and professor of integrative biology, first initiated fire ant research at the university in 1986 by bringing to the university two young researchers...
