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.

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.

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.

Amazon reported a slight drop in greenhouse gas emissions, but its total footprint remains millions of metric tons larger than past years, according to the company's sustainability report. Aseem Prakash, professor of political science and director of the Center for Environmental Politics at the UW, is quoted.

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.

A new study from the UW found that persistent heat waves in the marine environment linked to climate change are leading to the deaths of hundreds of thousands of seabirds several months later. Julia Parrish, UW professor of biology and of aquatic and fishery sciences and director of COASST and lead author of the study, is inteviewed.

New electronic devices? New data storage methods? UW Physics & Materials Sciences Professor Xiaodong Xu studies the properties of single atomic layer semiconductors. He looks for new materials and new ways to control electrical conductivity.

Calls to overhaul the police go back decades. But violent episodes of police enforcement continue. So do violent outpourings on the street. Magda Boutros, assistant professor of sociology at the UW, is quoted.

The decades-old government housing discrimination program commonly called redlining continues to shape which of Seattle's streets are most dangerous for pedestrians. James Gregory, professor of history at the UW, is quoted.

As the world's best-known fictional archaeologist goes after what may be his last ancient mystery in "Indiana Jones and the Dial of Destiny," new generations of real-life archaeologists are ready to dig in with 21st-century technologies and sensibilities. Sara Gonzalez, associate professor of anthropology at the UW, is quoted. Peter Lape, professor of anthropology at the UW, is referenced.

An analysis of foraging societies from around the world has found that women hunt in the vast majority of those looked at, confirming that the idea of gender division in providing food is a myth. Cara Wall-Scheffler, affiliate assistant professor of anthropology at the UW, is quoted.

Three new faculty books from the University of Washington cover wide-ranging topics: oysters, the moral contradictions of religion, and Cherokee creature names and environmental relationships.

A team led by scientists and engineers at the University of Washington has announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of papers published June 14 in Nature and June 22 in Science, they report that, in experiments with flakes of semiconductor materials — each only a single layer of atoms thick — they detected signatures of “fractional quantum anomalous Hall” (FQAH) states. The team’s discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons — strange “quasiparticles” that have only a fraction of an electron’s charge. Some types of anyons can be used to make what are called “topologically protected” qubits, which are stable against any small, local disturbances.

No one can really describe what milk is -- least of all the people who think most often about it. Melanie Martin, assistant professor of anthropology at the UW, is quoted.
