New Study Shows How Deep-learning Technology Can Improve Brain Imaging

Compare these two images of a slice of brain tissue from a rat. The PSSR method applies deep learning to a low resolution image from a scanning electron microscope (left) to yield a higher resolution image (right).

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.

The University of Texas at Austin and other partners of the Giant Magellan Telescope (GMT) announce the fabrication of the sixth of seven of the world's largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical telescope before. The sixth 8.4-meter (27.5 feet) mirror — about two stories high when standing on edge — is being fabricated at The University of Arizona's Richard F. Caris Mirror Lab and will take nearly four years to complete.

Exploring Passive RFID Tag Use For Sensory Technology

Recent PhD graduate Swadhin Pradhan and his advisor Professor Lili Qiu.

When was the last time you changed out a battery in your house? Studies show that battery-powered devices are used substantially in modern times; Americans use nearly 3 billion batteries every year. Batteries are currently popular because they are able to make electric devices, such as flashlights and watches, portable. However, our usage of batteries extends further than just portable electronic devices.

Finkelstein Receives Welch Foundation’s Norman Hackerman Award

The Welch Foundation today announced that Ilya J. Finkelstein, an associate professor of molecular biosciences at The University of Texas at Austin who has been researching the coronavirus and the gene-editing tool CRISPR, will receive the 2021 Norman Hackerman Award in Chemical Research. Having already made significant scientific contributions in chemistry and biochemistry, he is being recognized as a rising star in his field.

Richard Taylor, clinical assistant professor in the School of Human Ecology, co-authored a study published in Frontiers in Public Health which estimated that 1.7 million vaccine doses are needed to reach herd immunity for COVID-19 in Travis County. A new model could help public health officials in Central Texas better manage what amounts to a much larger vaccination campaign than was carried out during the last pandemic.
