Scientists have observed for the first time what it looks like in the key memory region of the brain when a mistake is made during a memory trial. The findings have implications for Alzheimer's disease research and advancements in memory storage and enhancement, with a discovery that also provides a view into differences between the physiological events in the brain during a correct memory versus a faulty one.

Xue-Xin Wei, a computational and theoretical neuroscientist, recently joined the Department of Neuroscience as an assistant professor. Wei grew up in Qingdao, China, before obtaining his undergraduate degree in mathematics at Peking University. His lab works at the intersection of computational/theoretical neuroscience, statistics, artificial intelligence and deep learning. He and his team work closely with experimental scientists to test predictions of computational models to form theory-experiment loops.

This month, hundreds of graduating College of Natural Sciences students will walk across a small outdoor stage, masked and socially distanced, and smile at the camera for friends and family mostly watching online.

Each year, the College of Natural Sciences bestows its highest honors for graduating seniors on a select group of students. These students, known as Dean's Honored Graduates demonstrate excellence across multiple domains, achieving not only academically but in scientific research, independent intellectual pursuits, leadership, service, entrepreneurship and community building. Here are biographies of the 33 outstanding students selected by College of Natural Sciences faculty for this distinction in 2021.

Researchers at The University of Texas at Austin have found a particular type of cell once thought to hinder the recovery process in people who have suffered strokes may actually promote the healing process following a brain injury. The findings, published April 27 in the journal Cell Reports, provides new insights for researchers seeking treatments for stroke and brain injury.

For more than a decade, the Aspire Awards have provided an occasion for faculty, staff and students to recognize undergraduate leaders in the College of Natural Sciences. The event celebrates undergraduate students from underrepresented groups in the sciences, recognizing their achievements in research, service and leadership. This year, 25 students were given Aspire awards in several categories. The event is a collaboration between the college's Office of Undergraduate Education and the student-led Black and Latinx Advocacy Council.

Two University of Texas at Austin undergraduate students, Briana Syed and Teddy Hsieh, have earned the prestigious Goldwater Scholarship, which honors outstanding students in STEM majors.

Neuroscience researchers often face challenges when using high-powered microscopes to capture clear images of brain tissue. Microscopes suffer from what researchers call the "eternal triangle of compromise" — image resolution, the intensity of the illumination the sample is subjected to, and speed compete with each other. For example, taking an image of the sample very quickly can result in a dark image, but subjecting a biological sample to more intense light can damage it.

Michela Marinelli, an associate professor of neuroscience and neurology, teaches a class particularly relevant as widespread misinformation becomes a hot topic in society.

The University of Texas at Austin is gearing up to welcome science enthusiasts everywhere to the Texas Science Festival. The virtual celebration features rapid-fire and deep-dive presentations by world-changing scientists, live hands-on demonstrations, explosive science, telescope viewings, opportunities to interact with experts from Texas' flagship public research institution and more.
