The extraordinary pace of Microsoft’s ascent is what stands out in retrospect. The company, which is marking its 50th anniversary next year, was well on its way to dominating its industry by the time it arrived in the Seattle region from Albuquerque in 1979. Seven years later, in March 1986, the company made its debut on the New York Stock Exchange, at a market value of more than $500 million. So what can be learned from a fresh look at Microsoft’s startup years? Margaret O'Mara, professor of history at the UW, is quoted.

Nuclear fission has powered our world and medical advancements for decades, yet some of its secrets have remained elusive. Aurel Bulgac, professor of physics at the UW, is quoted.

The hunt for dark matter is shifting from particles to waves named after a laundry detergent. Gray Rybka, associate professor of physics at the UW, is quoted.

The Vera C. Rubin Observatory’s 8.4-meter Simonyi Survey Telescope in Chile has now been equipped with all three of its mirrors, plus a camera for good measure. James Davenport, research assistant professor of astronomy at the UW, is quoted. The UW's Željko Ivezić and Mario Jurić, both professors of astronomy, are mentioned.

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.

Experts at the UW have focused their lens on a rather unconventional subject of study – the link between the ability to view stars free from light pollution and an interest in astronomy. Rodolfo Cortes Barragan, a research scientist at the UW Institute for Learning & Brain Sciences, and Andrew Meltzoff, professor of psychology and co-director of the UW Institute for Learning and Brain Sciences, are quoted.

Scientists at the UW have recreated the distinctive spiral shapes of shark intestines in 3D-printed pipes in order to study the unique fluid flow inside the spirals. Their prototypes kept fluids flowing in one preferred direction with no need for flaps to control that flow and performed significantly better than so-called "Tesla valves." The UW's Ido Levin, postdoctoral researcher in chemistry, and Alshakim Nelson, professor of chemistry, are quoted.

Researchers from the University of Washington have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup. The team built a flexible pipe with an interior helical structure inspired by the anatomy of shark intestines â creating a prototype inspired by biology but with applications in engineering and medicine.

As students and their professors head back to college classrooms and lecture halls this fall, the elephant in the room is ChatGPT. Katy Pearce, associate professor of communication at the UW, is quoted.

The new movie “AfrAId" is among two centuries of entertainment about malicious artificial intelligence. Why are we so obsessed? Margaret O'Mara, professor of history at the UW, is quoted.

Statistics professor Zaid Harchaoui, working at the intersection of statistics and computing, explores what AI models do well, where they fall short, and why.

NASAâs upcoming Nancy Grace Roman Space Telescope will look for âfossilsâ of galaxy formation by conducting high-resolution imaging studies. Through a grant from NASA, astronomers are designing a set of possible observations called RINGS â the Roman Infrared Nearby Galaxies Survey â that would collect these images, and the team is producing publicly available tools that the astronomy community can use once Roman launches and starts collecting data.

A new study has found galaxies with more neighbors tend to be larger than their counterparts that have a similar shape and mass, but reside in less dense environments. In a paper published Aug. 14 in the Astrophysical Journal, the team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the relationship between a galaxyâs size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.

"Elon Musk recently pronounced that the next Neuralink project will be a “Blindsight” cortical implant to restore vision...Unfortunately, this claim rests on the fallacy that neurons in the brain are like pixels on a screen. It’s not surprising that engineers often assume that “more pixels equals better vision.” After all, that is how monitors and phone screens work," write Ione Fine and Geoffrey Boynton, professors of psychology at the UW.

The brainy machines are predicting global weather patterns with new speed and precision, doing in minutes and seconds what once took hours. Chris Bretherton, professor emeritus of atmospheric sciences and of applied mathematics at the UW, is mentioned.
