Before mouths existed, animals still had to eat. @ucdavis.bsky.social researchers found that Dickinsonia, a 550-million-year-old, pancake-shaped creature, fed by absorbing nutrients from microbial mats on the seafloor. It’s the strongest evidence yet of how Earth’s earliest animals survived.

Happy First Day of Classes, Aggies! Whether you're just joining Letters and Science or returning for another quarter, we're thrilled to welcome you to campus. Let's have an amazing quarter! 💙💛 @ucdavis.bsky.social

IPN collaborator Dr. Uri Manor at @ucsandiego.bsky.social reveals that #psychedelics as well as non-hallucinogenic analogues developed at the #UCDavisIPN can grow new synapses in the cochlea of mice which could open new horizons for treating age-related hearing loss.

Our researchers found that some disposable electronic cigarettes & vape pods emit more toxic metals like lead & nickel than traditional cigarettes. This can help consumers understand health risks & make informed decisions. #UCDavisDelivers...consumer answers. #UCDD https://bit.ly/47muNAs

The U.S. has been wrestling with redistricting since its founding. @ucdavis.bsky.social experts explain how gerrymandering has influenced elections for centuries and why today’s redistricting fights go far beyond #Texas and #California. Learn more: #UCDavis #Voting #Redistricting #Politics

When you think of @uofcalifornia.bsky.social, you may think of higher education or research, but you should also think of the grocery store. Next time you're doing a grocery run, thank UC Davis (and our sister campuses) for some of your grocery favorites: ucdav.is/4mRlY6E

There are just 19 more days until Fall quarter kicks off at @ucdavis.bsky.social! #DidYouKnow that almost all #Aggies pass through our college during their time here? We're incredibly proud to have the largest student body in the UC system. Visit lettersandscience.ucdavis.edu/ to get to know us!

From Madrid to Davis, Kate Villegas’s study abroad journey transformed her academic path and personal growth. As a double-major in human development and communications, Kate chose to spend a semester in Spain—studying sociology, practicing Spanish and building lifelong friendships.

$2 in economic activity is generated for every $1 the federal government invests in science. Science spending pays off. Tell Congress: Investing in science leads to a stronger America #SpeakUp4Science https://bit.ly/4mgBMQ9

UC Davis & @ucsanfrancisco.bsky.social scientists completed a clinical trial on a new cancer drug for pet cats with squamous cell carcinoma. Researchers believe it will also be effective for humans with similar head and neck cancers. Read more about the clinical trial: ucdav.is/46dxcfM

What does democracy mean if it excludes people based on race, gender or class? @ucdavis.bsky.social philosopher Elvira Basevich studies the writings of W.E.B. Du Bois to explore what a truly inclusive democracy could look like today. Visit our magazine to read more. #UCDavis #LaborDay #Democracy

A forthcoming book by UC Davis science historian Emily Merchant explores how eugenics -- the idea that social inequality is rooted in genetics -- is rising once again in the form of polygenic screening of embryos @ucdlands.bsky.social lettersandsciencemag.ucdavis.edu/science-tech...

This summer, students from various disciplines joined @ucdavis.bsky.social History Professor Kathy Stuart in Vienna, Austria, for the learning opportunity of a lifetime! Learn more about how you can join their next trip: bit.ly/45NjD6N @history-ucdavis.bsky.social

UC Davis student Sam Garcia found her path through a history project uncovering a forgotten Black community in Yolo County. The research led to lesson plans, a public exhibit, and inspired six students to pursue grad studies. Learn more: ucdav.is/3JwDiin #CaliforniaHistory #BlackHistory

Prof. Cecilia Tsu led an interdisciplinary team of undergraduate and graduate students on this research project! At #ucdavis undergrads have the opportunity to graduate level #research. www.ucdavis.edu/student-rese...

How quickly is the universe really expanding? Using polarization data from the Cosmic Microwave Background, Lloyd Knox and his team contributed to a new study that strengthens the standard cosmological model while adding fresh insight into the “Hubble tension.” #UCDavisDelivers #UCDD

What do t-shirt drawers, weather systems, and quantum physics have in common? Mathematics! @ucdavis.bsky.social Professor Anne Schilling’s research on Markov chains is uncovering the underlying rules that shape probability and prediction, with applications from daily life to advanced science.

From dark matter discoveries to economic policy insights, our faculty continue to shape global conversations. In July alone, our experts were featured in outlets including The Los Angeles Times, Forbes, USA Today, Newsweek, and more. Check out all of the highlights:

The recent magnitude 8.8 Kamchatka earthquake -- one of the most powerful recorded by modern instruments -- underscores the importance of earthquake risk forecasting. But how do scientists forecast earthquake risk?

Christina Thomas is reawakening a language, and with it, the heartbeat of her people. As a doctoral candidate in Native American Studies at @ucdavis.bsky.social, she’s preserving Numu Yadooana, the Northern Paiute language, and sharing it with the next generation. #UCDavisDelivers

Tariffs can bring short-term benefits to the U.S. economy, but at what cost? @ucdavis.bsky.social Economist Ina Simonovska’s new research shows that while tariffs may reduce trade deficit and boost welfare, retaliation from global partners and supply chain complexities could erase those gains.

What makes psychedelics powerful isn’t just hallucinations, it’s their ability to reshape the brain. @ucdavis.bsky.social research shows non-hallucinogenic versions do the same, a discovery that could pave the way for safer, targeted treatments for depression and other mental health conditions.

What if you could keep the brain-healing effects of LSD, without the hallucinations? That’s exactly what one @ucdavis.bsky.social professor and his team set out to do. Their new compound, JRT, changes just two atoms in the LSD structure but dramatically reduces psychedelic effects.

Similar to @ucdavis.bsky.social, UCLA is a global leader in research, innovation, education, and healthcare. The federal government’s $1B demand would devastate the nation’s top public research university, cut off life-saving care, and halt tech and economic growth. #StandUpForUC.

From the @ucdavis.bsky.social campus to deep underground, Aggie students are helping push the boundaries of physics. Assistant Professor Matthew Citron's team designed, built, and installed a dark matter detector sensitive enough to search for particles we’ve never seen before. #UCDavisDelivers

“As a public university, we are stewards of taxpayer resources, and a payment of this scale would completely devastate our country’s greatest public university system as well as inflict great harm on our students and all Californians.” —UC President James B. Milliken

Do you ever hold off on reaching out to friends or checking in on loved ones? Sometimes we assume that our messages won't make much of an impact, but one @ucdavis.bsky.social psychology professor is proving us wrong. Egocentrism can lead us to misjudge how our actions will be received.

On @npr.org’s The Sunday Story, IPN Director, @deolsonlab.bsky.social explains how #psychedelics may treat depression by promoting brain plasticity and why he’s working to engineer out the trip. 🎧 Hear more on the psychedelic renaissance and where science is headed:

An interdisciplinary research collaboration between the California Lighting Technology Center, or CLTC, and the Center for Mind and Brain, or CMB, The Color Lab is part of an effort to implement human-centric lighting designs to optimize well-being.
