Scientists Study How DNA Repairs Itself Through Single Molecule Imaging

​A group of scientists from UT Austin's Finkelstein Laboratory, headed by assistant professor in Molecular Biosciences Ilya Finkelstein, have imaged proteins which repair DNA and gained new insights into how the body regulates DNA repair. The research, which uses novel single-molecule imaging techniques partially developed by Finkelstein, could lead to a better understanding of how cancerous cells repair their DNA.

Bacteria Take "RNA Mug Shots" of Threatening Viruses

Bacteria Take "RNA Mug Shots" of Threatening Viruses

Scientists from The University of Texas at Austin, the Stanford University School of Medicine and two other institutions have discovered that bacteria have a system that can recognize and disrupt dangerous viruses using a newly identified mechanism involving ribonucleic acid (RNA). It is similar to the CRISPR/Cas system that captures foreign DNA. The discovery might lead to better ways to thwart viruses that kill agricultural crops and interfere with the production of dairy products such as cheese and yogurt.

Award from Cancer Agency Supports Bringing Researcher to UT Austin

Award from Cancer Agency Supports Bringing Researcher to UT Austin

A $6 million award from the Cancer Prevention and Research Institute of Texas (CPRIT) will underwrite The University of Texas at Austin's hiring of a leading cancer researcher from Johns Hopkins University School of Medicine to serve as chair of the Department of Molecular Biosciences.

Scientists Find Leukemia’s Surroundings Key to its Growth

Scientists Find Leukemia’s Surroundings Key to its Growth

Researchers at The University of Texas at Austin have discovered that a type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous.

A new chair has been selected for the Department of Molecular Biosciences. Dan Leahy, a structural biologist and Professor of Biophysics & Biophysical Chemistry at Johns Hopkins University School of Medicine, will assume the role in January.

Chemistry in Mold Reveals Important Clue for Pharmaceuticals

Chemistry in Mold Reveals Important Clue for Pharmaceuticals

​In a discovery that holds promise for future drug development, scientists have detected for the first time how nature performs an impressive trick to produce key chemicals similar to those in drugs that fight malaria, bacterial infections and cancer.

Researchers Build Nanoscale Autonomous Walking Machine from DNA

Researchers Build Nanoscale Autonomous Walking Machine from DNA

Researchers at The University of Texas at Austin have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or drug targeting.

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

Study Shows Common Molecular Tool Kit Organisms Share Across Tree of Life

Study Shows Common Molecular Tool Kit Organisms Share Across Tree of Life

Researchers created the world’s largest protein map, identifying nearly 1,000 protein complexes that are shared across the tree of life. This image shows a small portion of that map.

In one of the largest and most detailed studies of animal molecular biology ever undertaken, researchers at The University of Texas at Austin and the University of Toronto discovered the assembly instructions for nearly 1,000 protein complexes shared by most kinds of animals, revealing their deep evolutionary relationships. Those instructions offer a powerful new tool for studying the causes of diseases such as Alzheimer's, Parkinson's and cancer.

Humanized Yeast illustrationDespite a billion years of evolution separating humans from the baker’s yeast in their refrigerators, hundreds of genes from an ancestor that the two species have in common live on nearly unchanged in them both, say biologists at The University of Texas at Austin. The team created thriving strains of genetically engineered yeast using human genes and found that certain groups of genes are surprisingly stable over evolutionary time.
