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.

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.

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.

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.

The overlap between humans and animals will increase substantially across much of the planet in less than 50 years due to human population growth and climate change, according to a collaborative study by scientists at the University of Michigan, the University of Washington and University College London. By 2070, the overlap between humans and more than 22,000 vertebrate species will rise across nearly 57% of Earthâs land, according to the team.

"In the face of shrinking populations, many of the world’s major economies are trying to engineer higher birth rates," co-writes Win Brown, an affiliate researcher at the Center for Studies in Demography & Ecology at the UW.

About one-fifth of all electricity customers in Washington will be eligible for a $200 energy credit this summer, funded through the state’s landmark climate law. Aseem Prakash, professor of political science at the UW, is quoted.

"I am a qualitative sociologist who works on issues of race/racism in and through science and technology. Specifically, my work is situated within a growing new area of inquiry, the sociology of the neurosciences." Oliver Rollins, assistant professor of American ethnic studies at the UW, is featured.

Jeffrey Riffell, a University of Washington professor of biology, wants to understand how female mosquitoes find find a host to bite for a bloody meal. His research has shown that hungry mosquitoes find us by following a trail of scent cues, including chemicals exuded by our skin and sweat, as well as the carbon dioxide gas we exhale with each breath. Mosquitoes also like colors, at least certain ones. His team is closing in on how the sense of smell and vision work together to help a mosquito zero in for the final strike and get her blood meal.
