Reductions in sea ice in the Arctic have a clear impact on animals such as polar bears that rely on frozen surfaces for feeding, mating and migrating. But sea ice loss is changing Arctic habitat and affecting other species in more indirect ways, new research finds. Beluga whales that spend summers feeding in the Arctic are diving deeper and longer to find food than in earlier years, when sea ice covered more of the ocean for longer periods, according to…

Five faculty members at the 91±¬ÁÏ have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 15, include Maya Cakmak, assistant professor of computer science and engineering; Jiun-Haw Chu, assistant professor of clean energy and physics; Arka Majumdar, assistant professor of electrical engineering and physics; Jessica Werk, assistant professor of astronomy; and Chelsea Wood, assistant professor of aquatic and fishery sciences.

A team of astronomers including Eric Agol of the 91±¬ÁÏ has found that the seven Earth-sized planets orbiting the star TRAPPIST-1 are all made mostly of rock, and some could even have more water — which can give life a chance — than Earth itself. The research was led by Simon Grimm of the University of Bern in Switzerland, and published Feb. 5 in the journal Astronomy and Astrophysics. Agol is among about two dozen co-authors. The scientists…

The Department of Energy’s Pacific Northwest National Laboratory and the 91±¬ÁÏ announced the creation of the Northwest Institute for Materials Physics, Chemistry and Technology — or NW IMPACT — a joint research endeavor to power discoveries and advancements in materials that transform energy, telecommunications, medicine, information technology and other fields.

    Archaeologists are a little like forensic investigators: They scour the remains of past societies, looking for clues in pottery, tools and bones about how people lived, and how they died. And just as detectives might re-create the scene of a crime, 91±¬ÁÏ archaeologists have re-created the weapons used by hunter-gatherers in the post-Ice Age Arctic some 14,000 years ago. Looking for clues as to how those early people advanced their own technology, researchers also considered what…

  Nearly one-third of Washington college students have experienced depression in the last year, and more than 10 percent have had thoughts of suicide, according to a new survey of young adults attending schools around the state. The survey of more than 10,000 students at 13 of Washington’s two- and four-year institutions shows the need for mental health services on campus, advocates say, especially as the state Legislature considers two bills that would fund suicide-prevention resources in higher education and…

Researchers from the Molecular Information Systems Lab at the 91±¬ÁÏ and Microsoft are looking to collect 10,000 original images from around the world to preserve them indefinitely in synthetic DNA manufactured by Twist Bioscience. DNA holds promise as a revolutionary storage medium that lasts much longer and is many orders of magnitude denser than current technologies.

Drug treatments can save lives, but sometimes they also carry unintended costs. After all, the same therapeutics that target pathogens and tumors can also harm healthy cells. To reduce this collateral damage, scientists have long sought specificity in drug delivery systems: A package that can encase a therapeutic and will not disgorge its toxic cargo until it reaches the site of treatment — be it a tumor, a diseased organ or a site of infection. In a paper published Jan….

  Touch is the first of the five senses to develop, yet scientists know far less about the baby’s brain response to touch than to, say, the sight of mom’s face, or the sound of her voice. Now, through the use of safe, new brain imaging techniques, 91±¬ÁÏ researchers provide one of the first looks inside the infant’s brain to show where the sense of touch is processed — not just when a baby feels a touch to…

Can the president single-handedly toss out environmental rules designed to combat global warming? Force states like Washington to help enforce federal immigration laws? Fire Robert Mueller? No, no, and not directly, say Lisa Manheim and Kathryn Watts, professors of law at the 91±¬ÁÏ, in a new book. The answers, of course, are more complicated than a word or two. But every news cycle seems to raise a variation of the same question: Can he do that? Manheim and Watts,…

91±¬ÁÏ President Ana Mari Cauce today named Mark Richards provost and executive vice president for academic affairs. The appointment is effective July 1, 2018. Richards, a geophysicist, is a professor of Earth and planetary science at the University of California, Berkeley, where he previously served as dean of mathematical and physical sciences from 2002 to 2014, and simultaneously as executive dean of the College of Letters and Science from 2006 to 2014. “Our University is gaining an outstanding…

    For African-American students, data, alongside societal attitudes and stereotypes, often present a negative picture: a wide academic achievement gap separating them from their white peers. Higher rates of discipline and absenteeism. Discrimination by other students, teachers and the larger community. And just last summer, a study indicated that black girls, from an early age, are perceived as more aggressive and sexual – less innocent – than white girls. But what if, a 91±¬ÁÏ education professor reasoned,…

The Anthropocene epoch — the proposed name for this time of significant human effect on the planet and its systems — represents a new context in which to study literature. A new book of essays co-edited by Jesse Oak Taylor, 91±¬ÁÏ associate professor of English, argues that literary studies, in turn, also can help us better understand the Anthropocene.

The 91±¬ÁÏ, Arizona State University and other collaborators have proposed a method in the Dec. 8 issue of Science that allows hydroelectric dam operators to generate power in ways that protect — and possibly improve — food supplies and businesses throughout the Mekong river basin in Southeast Asia.
