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.

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 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.

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.

The four new graduates honored as College of Arts & Sciences Dean's Medalists for 2023 are all working to improve our world, in different ways. 

A poem by alum Patricia Clark (BA, 1974), about a UW astronomy class she took 51 years ago, is now headed to the moon on a NASA flight. 

By studying the light atoms emitted when stimulated by a laser, they were able to detect vibrations sometimes referred to as atomic "breathing," a feature fundamental to nature's building blocks. The UW's Mo Li, professor of physics and of electrical and computer engineering; Adina Ripin, a doctoral student in physics; and Ting Cao, assistant professor of materials science and engineering, are quoted.

Astronomers spotted a stellar explosion in the Pinwheel Galaxy last month. Within a week, James Davenport, research assistant professor of astronomy at the UW, and his colleagues were searching the stars for radio signals from alien civilizations who might have seen the same thing.

Sapna Cheryan, professor of psychology at the UW, and her colleagues want U.S. Education Secretary Miguel Cardona to consider not telling grads to, "Follow your passions," in his commencement address on Saturday. Instead, in this interview Cheryan shares alternative advice for graduating students.

Meghna Shankar, graduating with degrees in physics and computer science, found joy and balance by also performing in the UW Symphony Orchestra. 

"Public understanding of science is essential for democracy. Misleading readers to score political points with an argument that scientists have exchanged merit and objectivity for progressive ideology is a disservice to science and the public alike," writes Carl Bergstrom, professor of biology at the UW, in a letter to the editor.

By analyzing records from the U.S. Social Security Administration, two scientists at the University of Washington and Ohio University have discovered that the popularity of certain month and season names for girls varies by geographic region in the continental United States. The name April dominates monthly names in southern states where spring arrives early in the year. June is more popular in northern states where spring blooms later. Autumn is also more prevalent in the northern U.S., a region known for its brilliant fall foliage.

Parents get an endless supply of rules and unsolicited opinions about what to do and what not to do with their kids. But the truth is there's no handbook. Shannon Dorsey, professor of psychology at the UW, is quoted.
