New research from the University of Washington investigated responses to sweetened beverage taxes using the purchasing behavior of approximately 400 households in Seattle, San Francisco, Oakland and Philadelphia. Researchers found that after the tax was introduced, lower-income households decreased their purchases of sweetened beverages by nearly 50%, while higher-income households reduced purchases by 18%.

In “Primary Trust,” which opens at Seattle Rep on Oct. 24 and runs through Nov. 24, playwright Eboni Booth brings audiences on a deep dive into the epidemic of adult loneliness. Nicole McNichols, associate teaching professor of psychology at the UW, is quoted.

Success in Gig Harbor comes as more schools are looking to reign in cell phones. Four of the five school districts in Kitsap County now have bans, a pair of which are new this fall. Central Kitsap, the lone holdout, plans to have a ban by early next year. Lucía Magis-Weinberg, assistant professor of psychology at the UW, is quoted.

"This time of year, aspiring elected officials insist that we must get tough on crime to keep us safe. 'Getting tough' almost always includes imposing more and longer prison sentences. Unfortunately, most of those claims are based on myths, fear, and half-truths. Therefore, voters should insist that calls for increased punishment be replaced by programs that can actually reduce crime, help victims, and increase public safety," writes David Trierweiler. Heather Evans, assistant professor of rehabilitation medicine at the UW School of Medicine, and Katherine Beckett, professor of sociology and of law, societies and justice at the UW, are mentioned.

A new study comparing the brains of children before and after COVID-19 found that adolescent girls’ brains had aged faster than expected during the social isolation and lockdowns brought on by the pandemic. Patricia Kuhl, professor of speech and hearing sciences at the UW and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

New research found that teens’ brains “aged” during the COVID-19 lockdowns due to the loss of social interaction. Girls were the most impacted. Patricia Kuhl, professor of speech and hearing sciences at the UW and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

Neuroimaging found girls experienced cortical thinning far faster than boys did during the first year of COVID lockdowns. The UW's Neva Corrigan, research scientist at the Institute for Learning and Brain Sciences, and Patricia Kuhl, professor of speech and hearing sciences and co-director of the UW Institute for Learning and Brain Sciences, are quoted.

COVID lockdowns, such as school closures, canceled sports activities and stay-at-home orders, prematurely aged teen brains by as much as four years, researchers from the UW found. Patricia Kuhl, professor of speech and hearing sciences at the UW and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

New research from the University of Washington found lockdowns during the COVID-19 pandemic resulted in unusually accelerated brain maturation in adolescents. This maturation was more pronounced in girls. When measured in terms of the number of years of accelerated brain development, the mean acceleration was 4.2 years in females and 1.4 years in males.

The research team hopes to survey at least 300 middle and high school students, teachers and parents this school year at western Washington schools with bans. Lucía Magis-Weinberg, assistant professor of psychology at the UW, is quoted.

A school in northwest Seattle is part of an experiment playing out in districts around the nation as educators try to rein in the widespread use of smartphones on campus. Restrictions and strategies for implementation vary. Educators have a long list of reasons for wanting cellphone-free policies, but formal research is limited on the impacts of school smartphone use and the effects of bans. Lucía Magis-Weinberg, assistant professor of psychology at the UW, is quoted.

Spraying pesticides can have unintended impacts on important pollinator species. Jeff Riffell, professor of biology at the UW, is quoted.

An international team led by researchers at the University of Washington has uncovered surprising details about mosquito mating, which could lead to improved malaria control techniques and even help develop precision drone flight. In a paper published Aug. 30 in the journal Current Biology, the team revealed that when a male Anopheles coluzzii mosquito hears the sound of female-specific wingbeats, his eyes âactivateâ and he visually scans the immediate vicinity for a potential mate.

Nick Riley's chemistry research aims to understand cellular processes involving sugars, which could one day lead to advances in treating a range of diseases.

"Rather than learn these same painful lessons [of banishment programs] over again, we suggest looking to other successful initiatives that involve skillful regulation of space, enforcement of conduct expectations, and multidepartment coordination rather than banning specific people from parts of the city," write Katherine Beckett, professor of sociology and of law, societies and justice at the UW, and co-author Lisa Daugaard.
