Natural history museums have entered a new stage of discovery and accessibility â one where scientists around the globe and curious folks at home can access valuable museum specimens to study, learn or just be amazed. This new era follows the completion of openVertebrate, or oVert, a five-year collaborative project among 18 institutions to create 3D reconstructions of vertebrate specimens and make them freely available online. The team behind this endeavor, which includes scientists at the University of Washington and its Burke Museum of Natural History & Culture, published a summary of the project March 6 in the journal BioScience, offering a glimpse of how the data can be used to ask new questions and spur the development of innovative technology.

Apparently humans aren't the only animals who are neat freaks. Find out how this small rodent and other animals also declutter. James Ha, emeritus research professor of psychology at the UW, is quoted.

A newly discovered genetic mechanism helped eliminate the tails of human ancestors. David Kimelman, professor emeritus of biochemistry at the UW, is quoted.

A team working on prolonging the lifespan of transplant organs took home the top prize in the 9th annual Hollomon Health Innovation Challenge at the UW. BioLegacy, made up of Seattle University and UW finance, mechanical engineering, and chemistry students, was awarded the $15,000 WRF Capital Grand Prize for its organ cryopreservation and rewarming innovation. The team was one of 22 that competed in this year’s final round of competition at the UW Foster School’s Buerk Center for Entrepreneurship. Other UW projects are mentioned.

Seattle scientist and conservationist Estella Leopold has died at the age of 97. Leopold spent most of her career at the University of Washington, teaching and learning about the distant past through pollen deposits. P. Dee Boersma, professor of biology at the UW, is quoted.

The traveling salesperson problem is one of the oldest known computational questions. Despite seeming simple, the problem is notoriously difficult. Recent work using geometric tools has created a new, faster algorithm, making the biggest runtime leap in decades. Co-developer Thomas Rothvoss, professor of mathematics and of computer science and engineering at the UW, is quoted.

A new study led by researchers at the UW and Northwestern University found about 80% of parents spoke to their children about the Black Lives Matter movement within a year of the murder of George Floyd. Andrew Meltzoff, professor of psychology and co-director of the UW Institute for Learning and Brain Sciences, is quoted.

You might not know it, but some moths can smell just as well as dogs. The nighttime insects use their antennae to sniff out flowers heavy with pollen up to a mile away. New research from the UW shows pollution in car exhaust can blunt the flowers’ scent – making it hard for pollinators to find the blossoms. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted.

An international team of scientists has blazed a new trail for studying how atoms respond to radiation, by tracking the energetic movement of electrons when a sample of liquid water is blasted with X-rays. Xiaosong Li, professor of chemistry at the UW, is quoted.

Air pollution is making it hard for some Washington state flowers to get pollinated, according to a new study in the journal Science. Jeff Riffell, professor of biology at the UW, is quoted.

Scientists at this University of Washington facility in the San Juan Islands are working to help sunflower stars — a type of sea star — grow and thrive once again after their populations along the West Coast were devastated by a mysterious disease. Jason Hodin, research scientist in the UW Department of Biology, is quoted.

Aliens might time their signals with a burst of supernova light. James Davenport, research assistant professor of astronomy at the UW, is mentioned.

In an experiment akin to stop-motion photography, an international team co-led by University of Washington scientists has isolated the energetic movement of an electron in a sample of liquid water â while âfreezingâ the motion of the much larger atom it orbits.

The research, involving primroses and hawk moths, suggests that air pollution could be interfering with plant reproduction. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted, and Jeremy Chan, a former graduate student, is pictured.

Byproducts of car exhaust disrupt pollination by degrading the floral scents that insects use to track down their favorite plants, according to new research. The UW's Jeff Riffell, professor of biology, and Joel Thornton, professor of atmospheric sciences, are quoted.
