Scientists at the University of Washington and Emory University report that an antibiotic sprayed on orchard crops to combat bacterial diseases slows the cognition of bumblebees and reduces their foraging efficiency. The study, published Feb. 9 in the Proceedings of the Royal Society B, focused on streptomycin, an antibiotic used increasingly in U.S. agriculture during the past decade.

An international research team, including scientists from the University of Washington, has established a new upper limit on the mass of the neutrino, the lightest known subatomic particle. In a paper published Feb. 14 in Nature Physics, the collaboration — known as the Karlsruhe Tritium Neutrino Experiment or KATRIN — reports that the neutrino’s mass is below 0.8 electron volts, or 0.8 eV/c2. Honing in on the elusive value of the neutrino’s mass will solve a major outstanding mystery in particle physics and equip scientists with a more complete view of the fundamental forces and particles that shape ourselves, our planet and the cosmos.

Two faculty members at the University of Washington have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 15, are Brianna Abrahms, an assistant professor in the Department of Biology, and Yulia Tsvetkov, an assistant professor in the Paul G. Allen School of Computer Science & Engineering.

The International Astronomical Union has launched the Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference to coordinate collaborative multidisciplinary international efforts with institutions and individuals — including researchers at the University of Washington’s DiRAC Institute — to help mitigate the negative impacts of satellite constellations on ground-based optical and radio astronomy observations as well as humanity’s enjoyment of the night sky.

New research from an interdisciplinary team at the University of Washington, Duke University and The Nature Conservancy shows how local temperature increases in the tropics – compounded by accelerating deforestation – may already be jeopardizing the well-being and productivity of outdoor workers.

As students resume in-person classroom education, University of Washington staff with the Educational Talent Search (ETS) program also move back into 14 partner middle and high schools in six Washington school districts, helping them gain the skills and confidence to pursue a college degree.

Many animals have tusks, from elephants to walruses to hyraxes. But one thing tusked animals have in common is that they’re all mammals — no known fish, reptiles or birds have them. But that was not always the case. In a study published Oct. 27 in the Proceedings of the Royal Society B, a team of paleontologists at Harvard University, the Field Museum, the University of Washington and Idaho State University traced the first tusks back to dicynodonts — ancient mammal relatives that lived before the dinosaurs.

The UW Climate Impacts Group, along with nine community, nonprofit and university partners, is launching a program of community-led, justice-oriented climate adaptation work across Washington, Oregon, Idaho and Montana. The Northwest Climate Resilience Collaborative will be founded with a five-year, $5.6 million grant from the National Oceanic and Atmospheric Association. The program will be one of eleven across the country funded through NOAA’s Regional Integrated Sciences and Assessments program.

The National Science Foundation has announced it will fund a new endeavor to bring atomic-level precision to the devices and technologies that underpin much of modern life, and will transform fields like information technology in the decades to come. The five-year, $25 million Science and Technology Center grant will found the Center for Integration of Modern Optoelectronic Materials on Demand — or IMOD — a collaboration of scientists and engineers at 11 universities led by the University of Washington.

The University of Washington and Carnegie Mellon University have announced an expansive, multi-year collaboration to create new software platforms to analyze large astronomical datasets generated by the upcoming Legacy Survey of Space and Time, or LSST, which will be carried out by the Vera C. Rubin Observatory in northern Chile. The open-source platforms are part of the new LSST Interdisciplinary Network for Collaboration and Computing — known as LINCC — and will fundamentally change how scientists use modern computational methods to make sense of big data.

Astronomers have long suspected that superflares, extreme radiation bursts from stars, can cause lasting damage to the atmospheres — and thus habitability — of exoplanets. A new study published in the Monthly Notices of the Royal Astronomical Society reports that they pose only a limited danger to planetary systems.
