AUSTIN, Texas — A team of American and Chinese researchers has revealed the detailed feather pattern and color of Microraptor, a pigeon-sized, four-winged dinosaur that lived about 120 million years ago. A new specimen shows the dinosaur had a glossy iridescent sheen and that its tail was narrow and adorned with a pair of streamer feathers, suggesting the importance of display in the early evolution of feathers, as presented in the March 9 edition of the journal Science.

The research was conducted by scientists at the Beijing Museum of Natural History, Peking University, The University of Texas at Austin, the University of Akron, and the American Museum of Natural History. (more…)

Mapping Tool Analyzes How Climate Change, Conflict and Aid Intersect in Africa

AUSTIN, Texas — Researchers have developed a new dynamic mapping tool that will help policymakers and other groups determine a country’s vulnerabilities to climate change and conflicts and show how these two issues intersect in Africa.

The pilot version of the tool was released this month by the Robert S. Strauss Center for International Security and Law at The University of Texas at Austin and additional data tools are expected to come online starting this spring. (more…)

Computer Scientist Developing Intersections of The Future With Fully Autonomous Vehicles

AUSTIN, Texas — Intersections of the future will not need stop lights or stop signs, but will look like a somewhat chaotic flow of driverless, autonomous cars slipping past one another as they are managed by a virtual traffic controller, says computer scientist Peter Stone.

“A future where sitting in the backseat of the car reading our newspaper while it drives us effortlessly through city streets and intersections is not that far away,” says Stone, a professor of computer science at The University of Texas at Austin. (more…)

New Molecule Has Potential to Help Treat Genetic Diseases and HIV

AUSTIN, Texas — Chemists at The University of Texas at Austin have created a molecule that’s so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.

It’s an important step along the path to someday creating drugs that can go after rogue DNA directly. Such drugs would be revolutionary in the treatment of genetic diseases, cancer or retroviruses such as HIV, which incorporate viral DNA directly into the body’s DNA. (more…)

New Ability To Regrow Blood Vessels Holds Promise For Treatment of Heart Disease

AUSTIN, Texas — University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs — a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.

The treatment method developed by Cockrell School of Engineering Assistant Professor Aaron Baker could allow doctors to bypass surgery and instead repair damaged blood vessels simply by injecting a lipid-incased substance into a patient. Once inside the body, the substance stimulates cell growth and spurs the growth of new blood vessels from pre-existing ones. (more…)

Researchers Discover Potential Key To Lowering Energy Costs of Cell Phones and Data Centers

AUSTIN, Texas — A systematic analysis of power usage in microprocessors could help lower the energy consumption of both small cellphones and giant data centers, report computer science professors from The University of Texas at Austin and the Australian National University.

Their results may point the way to how companies such as Google, Apple, Intel and Microsoft can make software and hardware that will lower the energy costs of very small and very large devices. (more…)

Nano-Sized Protein Clusters Address Major Challenge of Drug Delivery

AUSTIN, TX — A new form of proteins discovered by researchers at The University of Texas at Austin could drastically improve treatments for cancer and other diseases, as well as overcome some of the largest challenges in therapeutics: delivering drugs to patients safely, easily and more effectively.

The protein formulation strategy, discovered by chemical engineering faculty members and students in the Cockrell School of Engineering, is unprecedented and offers a new and universal approach to drug delivery — one that could revolutionize treatment of cancer, arthritis and infectious disease.
