Over the last six years, faculty, staff and students from across the College of Natural Sciences have submitted hundreds of images from their scholarly research for our annual Visualizing Science competition, and these images have been viewed by tens of thousands of people. The submitted images, often beautiful and stunning, are the ones that spoke to their creators, inspiring and informing them as they followed their scientific passions.

In recent weeks, a pair of researchers received two of the biggest prizes in science, the Breakthrough Prize and the Lasker Award. Both women seized the moment to shine a light on something too frequently cast into the shadows—namely that STEM fields need more women and people from underrepresented communities involved and made welcome in their pursuits.

Last year, University of Texas at Austin alumnus Michael Young won the Nobel Prize in Physiology or Medicine for discovering the molecular mechanism behind circadian rhythms. Circadian clocks are critical for the health of all living things, acting as the internal timekeepers in plants and animals that help to synchronize functions like eating and sleeping with our planet's daily rhythm of light and dark.

The world's most widely used weed killer may also be indirectly killing bees. New research from The University of Texas at Austin shows that honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria.

With the new academic year in full swing, there are some new faces around the College of Natural Sciences. Meet the 20 new tenured and tenure-track faculty members, whose expertise ranges from astrophysics to nutrition to mathematics.

Deep in the night in muddy African rivers, a fish uses electrical charges to sense the world around it and communicate with other members of its species. Signaling in electrical spurts that last only a few tenths of a thousandth of a second allows the fish to navigate without letting predators know it is there. Now scientists have found that the evolutionary trick these fish use to make such brief discharges could provide new insights, with a bearing on treatments for diseases such as epilepsy.

In the same way that barcodes on your groceries help stores know what's in your cart, DNA barcodes help biologists attach genetic labels to biological molecules to do their own tracking during research, including of how a cancerous tumor evolves, how organs develop or which drug candidates actually work. Unfortunately with current methods, many DNA barcodes have a reliability problem much worse than your corner grocer's. They contain errors about 10 percent of the time, making interpreting data tricky and limiting the kinds of experiments that can be reliably done.

A complex genetic analysis has biologists re-evaluating some long-held beliefs about the way societies evolved following the invention of agriculture—by six-legged farmers.

Using genetic samples and computer simulations, evolutionary biologists have made a glass-half-full forecast: Corals in the Great Barrier Reef have enough genetic variation to adapt to and survive rising ocean temperatures for at least another century, or more than 50 years longer than previous estimates have suggested.
