Tripods might be popular in science fiction, but there are no truly three-limbed animals, living or extinct, on Earth. Tracy Thomson has been thinking about why that may be, and the value of considering what evolution cannot do.Af Andy Fell, UC Davis

Ecosystems dominated by high-powered competitors are more efficient at recycling nutrients than low-powered systems, argues UC Davis paleontologist Geerat Vermeij in a new paper. The idea ties together evolution and ecology, and explains how ecosystems may have evolved to become more efficient since life appeared on Earth.…

When Biswanath Mukherjee came to UC Davis in 1987, the only telephones were landlines and the internet was something for academics and scientists. Now his work on networks -- including the first network firewall, demonstrated in his lab -- has anticipated multibillion dollar industries.Af Andy Fell, UC Davis

UC Davis paleontologist Ryosuke Motani and Chinese colleagues recently described a new and curious fossil. The 250 million-year-old animal was a marine reptile that seems to have lived much like the modern platypus, hunting by touch in dark or muddy water with its sensitive snout.Af Andy Fell, UC Davis

Mathematics is the language of the universe, and mathematicians can use this language to help people better understand the world. I talked to some UC Davis mathematicians about the problems they work on and why they are important. From quantum computers to the movement of subatomic particles and microorganisms swimming through fluids, it’s a journe…

A year ago this week, a series of fires broke out in Napa, Sonoma, and Mendocino counties, one of California’s best-known wine growing regions. While 90 percent of the grapes in Napa County had been harvested, a few vineyards still had grapes on the vine, including at the UC Davis experimental station in Oakville. Wildfire smoke can ruin wine. Anit…

Traumatic experiences, such as maltreatment as children, can influence how our mind and body react to stressful situations. UC Davis psychologist Paul Hastings and colleagues at the University of Washington have shown that intensive training for parents referred to Child Protective Services can improve physiological reactions to stress in their you…

We know that previous experience can affect how we remember things, but how does this work at a molecular level? UC Davis neuroscientist Brian Wiltgen talks about previous work showing how new memories can build on existing networks.Af Andy Fell, UC Davis

Spinal injuries are life changing, but research is showing that the body is better than thought at adapting to and recovering from injury. UC Davis bioengineer Karen Moxon talks about how therapies can help rats can take steps after spinal injury. More information: https://www.ucdavis.edu/news/working-around-spinal-injuries…

UC Davis biologist Harris Lewin talks about the Earth BioGenome Project, an ambitious effort to sequence the DNA of all complex life on Earth. The organizers plan to make the data available for research while also making sure source countries and traditional owners benefit.Af Andy Fell, UC Davis

For Judy Callis, teaching is about helping students make connections, between the biochemistry they learn in her lectures, what they have learned in other classes and their own life experiences.Now Callis, a biochemist who studies the ubiquitin protein system in plants, has been awarded the UC Davis Prize for Undergraduate Teaching and Scholarly Ac…

20 years ago Putah Creek near the UC Davis campus was a dry, trash-filled ditch. Then a lawsuit led to the Putah Creek Accord, which mandated year-round water flows to help protect fish and habitat. Kat Kerlin hears how restoring water has brought the creek back to life.Af Andy Fell, UC Davis

Glass and wine have gone together for thousands of years. A new book, "The Glass of Wine" by Jim and Penelope Shackelford, explores the science, history and artistry that goes into this perfect pairing.Af Andy Fell, UC Davis

When fires ripped through suburban Santa Rosa last year they may have done more than reduce homes to ashes. They could have created unknown or previously unrecognized health hazards in the smoke and ash. UC Davis graduate student Gabby Black is part of the team trying to figure out what is in the ash and air.…

Studying Prozac in Monkeys by Andy Fell, UC DavisAf Andy Fell, UC Davis

If you’ve ever tried to untangle a pair of earbuds, you’ll understand how loops and cords can get twisted up. DNA can get tangled in the same way. UC Davis biomathematician Mariel Vazquez talks about her work on the math of how DNA can be cut and reconnected. The math involved turns out to be involved in other fields as well.…

For the first time, astronomers have observed an object through both visible light and gravitational waves. UC Davis physicist Stefano Valenti, one of the astronomers whose telescopes recorded the colliding neutron stars, talks about the discovery.Af Andy Fell, UC Davis

Conventional wisdom says that our eyes are drawn to objects that stand out from the background. But this "magpie theory" of visual attention is wrong, says John Henderson of the UC Davis Center for Mind and Brain. A new study from Henderson's lab shows that attention is drawn to areas of a scene that are "meaningful" instead.…

South American capuchin monkeys are curious animals that readily learn new skills. UC Davis graduate student Brendan Barrett talks about his work studying how these monkeys learn from each other.Af Andy Fell, UC Davis

UC Davis planetary scientist Sarah Stewart proposes a new kind of planetary object, a giant spinning mass of vaporized rock called a "synestia."Af Andy Fell, UC Davis

Plant biologist Siobhan Brady talks about the science of roots, and how important they are for plants to survive and thrive.Af Andy Fell, UC Davis

Neanderthals were our closest relatives, and bits of their DNA live on in our genome. UC Davis evolutionary biologist Graham Coop talks about his work on the fate of Neanderthal DNA in the modern human genome.Af Andy Fell, UC Davis

UC Davis astronomer Marusa Bradac is looking for the first galaxies that appeared in the universe. She's using the Hubble Space Telescope and the Keck telescopes in Hawaii, as well as a gigantic lens in the sky to spot objects emerging from the fog of the cosmic dark ages.Af Andy Fell, UC Davis

Even the simplest organisms are hard to predict. Computer scientist Ilias Tagkopoulos. UC Davis Genome Center, talks about the model he and colleagues have built for the bacterium E. coli. The model could act as a 'crystal ball' that helps researchers design better experiments. Tagkopoulos says this is an exciting time to be on the interface of bio…

Growing sunflowers follow the sun during the day, and turn back overnight so they face the rising sun in the morning. UC Davis biologists now show how this is controlled through the plant's circadian clock.Af Andy Fell, UC Davis

UC Davis microbiologist Katy Ralston has discovered that a parasitic amoeba kills other cells by taking small bites or "nibbling." This turns out to be a fundamental process in cell biology.Af Andy Fell, UC Davis

Nectar attracts bees and other pollinators, but it isn't always sweet. A UC Davis scientist is looking at how microbes that live in nectar alter it, and what role these microorganisms play in the dance between flowers and pollinators.Af Andy Fell, UC Davis

The function of zebra stripes has puzzled people for millennia. UC Davis biologists put to the test one theory -- that the stripes confuse biting flies by disrupting polarized light.Af Andy Fell, UC Davis
