When tawny crazy ants move into a new area, the invasive species is like an ecological wrecking ball — driving out native insects and small animals and causing major headaches for homeowners. But scientists at The University of Texas at Austin have good news, as they have demonstrated how to use a naturally occurring fungus to crush local populations of crazy ants. They describe their work this week in the journal Proceedings of the National Academy of Sciences.

As greenhouse gases like carbon dioxide continue to pile up in the atmosphere, the world is experiencing more destructive extreme weather events like hurricanes, heatwaves, floods and droughts. A new study, published earlier this month in the scientific journal Nature Plants, finds that as Earth continues to warm, a certain group of trees, called nitrogen-fixing trees, may be able to help forests remove more heat-trapping CO₂ from the atmosphere than previously thought.

In honor of Valentine's Day, we're taking a look at some evolutionary lessons about love and attraction from College of Natural Science researchers in the Department of Integrative Biology.

Until COVID-19, few people alive today had experienced the chaos and destruction of a really bad pandemic, one that has at times ground businesses, schools and social lives to a near standstill and killed millions globally. But did you know that we aren't alone in being battered by a global infectious disease? Frogs are also struggling through their own pandemic that, according to biologist Kelly Zamudio, has several eerie parallels with COVID-19. Perhaps our own encounters with a pandemic will give us new sympathy for our slimy, bug-eyed friends.

Tropical forests are being deforested at an alarming rate, but also have the potential to regrow naturally on abandoned lands. A study published this week in Science shows that regrowing tropical forests recover surprisingly fast, and after 20 years can attain nearly 80% of the soil fertility, soil carbon storage, structure and tree diversity of old-growth forests. The study concludes that natural regeneration is a low-cost, nature-based solution for climate change mitigation, biodiversity conservation and ecosystem restoration.

While switchgrass has been seen as useful as a clean-burning source of renewable fuel, it also has the ability to pull carbon out of the atmosphere and store it underground in its substantial root system. Atmospheric carbon is a major contributor to climate change and finding ways to sequester it underground could have impacts on efforts to mitigate the catastrophic effects of climate change.

Few developments have rocked the biotechnology world or generated as much buzz as the discovery of CRISPR-Cas systems, a breakthrough in gene editing recognized in 2020 with a Nobel Prize. But these systems that naturally occur in bacteria are limited because they can make only small tweaks to genes. In recent years, scientists discovered a different system in bacteria that might lead to even more powerful methods for gene editing, given its unique ability to insert genes or whole sections of DNA in a genome.

Because they are critical in maintaining our food supply, a lot of research and public attention has been focused (rightly) on the health of domesticated honey bees. On the other hand, native bees also play critical roles in their environments, including pollinating flowers and agricultural crops. Unfortunately, hundreds of North American native bee species are in decline, due to a variety of factors including loss of habitat, nutritional stress, climate change and exposure to pathogens and agrochemicals.

William H. Press, a computer scientist and computational biologist at The University of Texas at Austin, will provide scientific perspective to the White House, as a recently named member of President Biden's Council of Advisors on Science and Technology (PCAST).

Biologists, naturalists and ecologists are typically known for conducting boots-on-the-ground field research, whether it is hiking through the jungles of Costa Rica to study rare frogs, paddling along Arctic coastlines to study sources of carbon or studying endangered birds in South Texas. But increasingly, technology is expanding the work these scientists can do beyond where their feet alone can take them.

Despite tremendous advances in medicine, tumors are challenging to cure because they are made up of heterogeneous cells. In other words, like human families, the individual cells of a tumor share some common traits and characteristics, but as the tumor expands, the cells also develop their own identities. And, as a result, some cells are more resistant to therapy than others and quicker to adapt and change.

Bees perform critical services in ecosystems, including by pollinating the plants that humans and other animals rely on for food. According to new research, however, bees exposed to multiple types of agricultural chemicals face much greater risk than previously understood. The finding, published in the journal Nature, has researchers raising the alarm that regulatory approval processes need updating to allow for more consideration of the environmental risks brought about by these chemicals' interactions.

A typical flu virus is so small that a thousand of them could fit in the width of a human hair.

The loss of plant species that are especially vulnerable to climate change might lead to bigger problems than previous studies have suggested, according to a new study published in the journal Proceedings of the National Academy of Sciences. If confirmed, the findings can help inform conservation strategies and lead to more accurate predictions about what ecosystems will look like in the future.

Steven Phelps, a professor of integrative biology and director of the Center for Brain, Behavior and Evolution at The University of Texas at Austin, has been awarded two prestigious fellowships in the same year related to his work on the biology of intimacy. He received both a 2021 Guggenheim Fellowship and was named a 2021-2022 Radcliffe Fellow by the Harvard Radcliffe Institute.
