The National Institutes of Health (NIH) has awarded a team led by Richard M. Crooks, a chemistry professor at The University of Texas at Austin, a $2 million grant to develop an inexpensive, at-home test for people diagnosed with heart failure.

Why Poison Frogs Don’t Poison Themselves

Why Poison Frogs Don’t Poison Themselves

The phantasmal poison frog, Epipedobates anthonyi, is the original source of epibatidine, discovered by John Daly in 1974. Epibatidine has not been found in any animal outside of Ecuador, and its ultimate source, proposed to be an arthropod, remains unknown. This frog was captured at a banana plantation in the Azuay province in southern Ecuador in August 2017. Credit: Rebecca Tarvin/University of Texas at Austin.

Don't let their appearance fool you: Thimble-sized, dappled in cheerful colors and squishy, poison frogs in fact harbor some of the most potent neurotoxins we know. With a new paper published in the journal Science, scientists are a step closer to resolving a related head-scratcher — how do these frogs keep from poisoning themselves? And the answer has potential consequences for the fight against pain and addiction.

Bryan Davies is an assistant professor in molecular biosciences and biotechnologist at the University of Texas at Austin, leading research into how to combat antibiotic-resistant bacteria and develop new antimicrobials to fight infection.

Couples Weather Bickering With a Little Help from Their Friends

Couples Weather Bickering With a Little Help from Their Friends

Every couple has conflict, and new research finds that having good friends and family members to turn to alleviates the stress of everyday conflict between partners. In fact, according to the study led by The University of Texas at Austin's Lisa Neff, social networks may help provide protection against health problems brought about by ordinary tension between spouses.

Scientists: New Device Accurately Identifies Cancer in Seconds (Updated)

Scientists: New Device Accurately Identifies Cancer in Seconds (Updated)

A team of scientists and engineers at The University of Texas at Austin has invented a powerful tool that rapidly and accurately identifies cancerous tissue during surgery, delivering results in about 10 seconds—more than 150 times as fast as existing technology. The MasSpec Pen is an innovative handheld instrument that gives surgeons precise diagnostic information about what tissue to cut or preserve, helping improve treatment and reduce the chances of cancer recurrence.

A team of scientists led by chemists Stephen Martin and James Sahn at The University of Texas at Austin have discovered what they say is a powerful pain reliever that acts on a previously unknown pain pathway. The synthetic compound, known as UKH-1114, is as effective at relieving neuropathic pain in injured mice as a drug widely used for pain relief called gabapentin, but it works at a much lower dose, with longer duration of action.

Scientists from The University of Texas at Austin took an important step toward safer gene-editing cures for life-threatening disorders, from cancer to HIV to Huntington's disease, by developing a technique that can spot editing mistakes a popular tool known as CRISPR makes to an individual's genome. The research appears today in the journal Cell.

About a third of all deaths in the U.S. could be prevented or substantially delayed by organ transplantation, according to a 2015 report from the U.S. military. The main bottleneck is that there is no practical way to preserve organs for more than a few hours. If you try to freeze a whole organ, water within and between cells forms ice crystals that cause the cells to rupture.

Birth Risks Rise Late in Doctors' Shifts, Researchers Find

The number of hours an obstetrician has been on the clock before an unscheduled delivery significantly influences risks to the mother and unborn baby, researchers report.

New Material Could Save Time and Money in Medical Imaging and Environmental Remediation

New Material Could Save Time and Money in Medical Imaging and Environmental Remediation

Chemists at The University of Texas at Austin have developed a material that holds the key to cheap, fast and portable new sensors for a wide range of chemicals that right now cost government and industries large sums to detect. The innovation could lead to major public health gains, as it holds the potential to drastically reduce the costs associated with cleaning-up accidental chemical spills, remediating old industrial sites, detecting radioactive contamination in drinking water, and operating medical and research imaging devices.
