Spend enough time with ChatGPT and other artificial intelligence chatbots and it doesn't take long for them to spout falsehoods. Described as hallucination, confabulation or just plain making things up, it's now a problem. Emily Bender, professor of linguistics at the UW, is quoted.

An asteroid discovery algorithm — designed to uncover near-Earth asteroids for the Vera C. Rubin Observatory’s upcoming 10-year survey of the night sky — has identified its first “potentially hazardous” asteroid, a term for space rocks in Earth’s vicinity that scientists like to keep an eye on. The roughly 600-foot-long asteroid, designated 2022 SF289, was discovered during a test drive of the algorithm with the ATLAS survey in Hawaii. Finding 2022 SF289, which poses no risk to Earth for the foreseeable future, confirms that the next-generation algorithm, known as HelioLinc3D, can identify near-Earth asteroids with fewer and more dispersed observations than required by today’s methods. That is important because, though scientists know of more than 2,000 near-Earth asteroids, they estimate that another 3,000 await discovery!

Big feet and short beaks have evolved in some hummingbirds that allow the birds to mooch nectar without helping the plant by transporting pollen. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

A new type of light detection and ranging (LiDAR) system invented by Mo Li, professor of physics and of electrical and computer engineering at the UW, and his team is poised to shake up what's possible within the LiDAR realm. The team built a laser beam-steering device with no moving parts and put it on a chip, which makes it 1000 times smaller than other LiDAR devices currently available. Putting it on a chip also makes the device compact and sturdy, as well as relatively easy and inexpensive to fabricate.

While it's hard to determine if today's poetry scene is any more successful than other times without taking a deep dive into data, there's currently a lot to celebrate in the Seattle poetry world: local poets are receiving critical acclaim and national recognition, a slew of books are being published and poets are choosing to move to the city to develop their craft. David Nikki Crouse, director of the UW's Creative Writing Program, is quoted.

A group of undergraduate and graduate students meet with Dean Harris regularly as the Arts and Sciences Advisory Council for Students (ASACS). "I consider these generous students as being among my greatest campus resources," writes the dean. 

Sam Altman has zero regrets about letting ChatGPT loose into the world. To the contrary, he believes it was a great public service. This is the story of the OpenAI CEO's ambitious, ingenious, terrifying quest to create a new form of intelligence. Emily M. Bender, professor of linguistics at the UW, is referenced.

Washington state has a unique connection to the period of time portrayed in the new Hollywood movie. Bruce Hevly, associate professor of history at the UW, is quoted.

A team led by researchers at the University of Washington reports that it is possible to imbue graphite — the bulk, 3D material found in No. 2 pencils – with physical properties similar to graphite’s 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won’t be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.

A fossil found in 2012 in the Chinese province of Liaoning appeared to show a badger-like mammal and a Labrador retriever-sized dinosaur, locked in what appears to be an eternal brawl. David Grossnickle, a postdoctoral scholar in biology at the UW, is quoted.
