The diverse dental features found among bats might help fill gaps in our understanding of how mammal teeth evolved. Scientists from the UW, publishing in Nature Communications, analysed and compared the jaws and teeth of more than 100 noctilionoid bats, revealing the developmental rules that explain the diverse range of dental features. Pictures from Sharlene Santana, professor of biology at the UW, are featured.

A recent study reveals the fascinating evolutionary journey of bat teeth and jaws. With over 200 species mostly found in the American tropics, noctilionoid bats possess a wide variety of jaw structures that have adapted to different diets. Sharlene Santana, professor of biology at the UW, is quoted.

There are more than 200 species of noctilionoid bats, mostly in the American tropics. And despite being close relatives, their jaws evolved in wildly divergent shapes and sizes to exploit different food sources. A paper published Aug. 22 in Nature Communications shows those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position. For example, bats with short snouts lack certain teeth, presumably due to a lack of space. Species with longer jaws have room for more teeth — and, like humans, their total tooth complement is closer to what the ancestor of placental mammals had.

From dark matter to planet-crushing asteroids, four ways the telescope could alter our understanding of the universe. Mario Jurić, professor of astronomy at the UW, is quoted.

The UWAA is proud to honor six extraordinary students across the UW whose stories exemplify Husky adaptability, tenacity and resolve. Each student receives a scholarship and was recognized at the Homecoming football game on Sat. Oct. 21, 2023.

In a paper published Sept. 6 in Physical Review Letters, an international team of researchers in the United States, Germany and France reported that a distinctive strategy they have used shows real promise to be the first approach to measure the mass of the neutrino. Once fully scaled up, their collaboration — Project 8 — could also reveal how neutrinos influenced the early evolution of the universe as we know it.

Briana Abrahms, a University of Washington assistant professor of biology and researcher with the UW Center for Ecosystem Sentinels, has been named a 2023 Packard Fellow for Science and Engineering, according to an Oct. 16 announcement from the David and Lucille Packard Foundation. As one of 20 new fellows across the country, Abrahms, who holds the Boersma Endowed Chair in Natural History and Conservation, will receive $875,000 over five years for her research.

"To me, being a first-generation student means the ability to bring awareness to the only 3% of aged-out foster youth that go on to obtain a college degree. I aged out of foster care at 17 and college was something that felt unobtainable to me. By being a first-generation student, I can be a beacon of hope for foster youth, spread awareness about educational difficulties foster youth face, and break the cycle of trauma." - Sara Smith (B.S., Speech & Hearing Sciences, 2024)

"Transferring does not have to be a difficult or scary time. Make sure you are using every resource given. If you don't know where to look, that is what your advisor is for. Success for you is success for all those who made the resources available to use." - Reyna Smith (B.S., Speech & Hearing Sciences, 2024)

"I would encourage first-gen students to never stop asking questions. I was often far too shy to do this during my undergraduate years. It took a long time to figure out how things worked and even longer to figure out how to succeed in academic spaces. There are UW employees whose sole role is to support you in this journey so find out who they are!" - Tasha Mosher, M.A. Applied Child & Adolescent Psychology: Prevention & Treatment

"I would also tell students to not count themselves out. You miss 100% of the shots you don't take and there is a reason you got into college in the first place. You are capable of anything you may put your mind to, even if no one before you has done it" - Kaitlynn Lilly (M.S. Applied Mathematics, 2023), Ph.D. Applied Mathematics, 2027

"As a transfer student, I was in a situation where I would not have been admitted to UW Seattle as a high school applicant. I needed that additional foundation at a community college to prepare me for the University and show the UW I was capable of academic achievement. After two years at the UW, I just felt like I wasn’t 'done' — so being here, belonging and becoming a staff member means being an example and showing how the differences in a diversity of backgrounds is what strengthens our entire community here at the UW." - Andrea Pardo (B.A., Comparative History of Ideas, 2006), Graduate Program Manager for Biology

"My first-gen experience has primarily impacted the development of my scientific communication skills. Due to prominent feelings of 'I am too dumb to be here' and "I don't have the background to understand this" throughout my undergraduate experience, I find it intuitive to explain problems from different angles (e.g., less abstract or mathematical) and be sensitive to students who do not have a strong math background. Basically, I am not afraid to be super 'handwavy' 😎." - Chad Hoyer, College of Arts & Sciences Chemistry Research Scientist

"I wear my first-gen status as a badge of honor. It represents strength, courage, and tenacity. I welcome every opportunity to relay this message to first-gen students and to solidify the belief that they belong here, and the University is greatly enriched by their unique perspectives!" - Kristie Spencer, Professor, Associate Chair, Graduate Program Coordinator; Department of Speech & Hearing Sciences
