Did you know that UW researchers have finally found out why Seeme -Stars die quickly? Sea stars have been wiped out by a bizarre lavish disease since 2013. This includes more than 90% of the single-communic sunflower seaside stars who support Seang forests by eating their greatest predators, seaweed sea urchins.
But international research efforts, including UW scientists, found the cause: a tribe of the bacterium Vibrio PectenicidaAccording to Drew Harvell, professor at the school for water and fishing sciences and Friday Harbor Laboratories, a “sneaky fool” that does not appear like other bacteria, Drew Harvell shows up. The researchers hope that the discovery will help to lead the management and recovery efforts for SEA stars and their ecosystems.
This great discovery is only a news excerpt from the university in autumn. Read for research on naval esters, dark matter, stroke rehabilitation and much more.

Sea Star Tracking
A marine heat wave met the west coast 10 years ago and contributed to the collapse of the Sonnenflumensee star in the waters before California. Without the starfish to keep their population in chess, native purple sea urchins rose in numbers and devastating seaweed forests. Students of the Technology Innovation Master's Program at the Global Innovation Exchange of the UW developed an underwater robot called Aquabot 2.0 and a AI-attacked dashboard to improve the process of pursuing naval esters. The team works with the UW Applied Physics Lab and Friday Harbor Labs.

Mapping of the night
In the Chilean Andes, Vera C. Rubin Observatory in the world gave the first insight into the 8.4-meter simonyi survey telescope in June. The legacy overview of space and time will help to disguise the secrets of dark matter, the dark energy and the history of our solar system. The observatory is a joint initiative of the National Science Foundation and the Office of Science of the Department of Energy. UW faculties, students and engineers helped design the observatory, built up his imaging software and developed algorithms to process the massive amounts of data that it collects.

Greener concrete
Researchers from UW and Microsoft have developed a low -carbon concrete by mixing dried, powder -shaped algae with cement, which cut the global heating potential of the concrete by 21% and at the same time maintains its strength. Cement production is responsible for up to 10% of global CO₂ emissions, but the inclusion of seaweed offers a more sustainable solution.

Help of stroke survivors
In a first medical first, UW medicine neurosurgeon have implanted a brain device in order to restore the movement in the event of stroke survivors. This study could redesign rehabilitation for the 800,000 Americans who have a stroke every year – and the millions that are already disabled. Dr. Jeffrey Ojemann from the UW School of Medicine: “We want to see if we can help you to get more functions back to you by stimulating the brain during the rehabilitation sessions.”

120-year legacy of freedom
In 1905, the UW received its first gift with cash that Philo Sherman Bennett Prize, a $ 400 enclosure on the east coast. The money financed an annual award of 25 US dollars of political science students for “the best essay on the principles of the Free Government”. Today the foundation distributes around 1,000 US dollars a year.
