UW experts develop first method for including migration uncertainty in population projections

Statisticians at the University of Washington have developed the first model for projecting population that factors in the vagaries of migration, a slippery issue that has bedeviled demographers for decades. Their work, published online this week in the Proceedings of the National Academy of Sciences, also provides population projections for all countries worldwide — and challenges the existing predictions for some, particularly the United States and Germany. “It turns out that for quite a few countries, migration is the single…

Study shows disparities in treatment for children with traumatic brain injuries

Children who suffer traumatic brain injuries can face a difficult road to recovery, requiring services such as physical therapy and mental health treatment for months or years to get their young lives back on track. When those children come from low-income households with limited English proficiency, there can be significant barriers in getting them the care they need. A recent University of Washington study found that less than 20 percent of rehabilitation providers in the state accepted Medicaid and also…

Historical role of translation studied in new book ‘Translation’s Forgotten History’

Book cover to "Translation's Forgotten History: Russian Literature, Japanese Mediation, and the Formation of Modern Korean Literature," by Heekyoung Cho, UW assistant professor of Asian languages and literature, published in March by Harvard University Press.

“Translation’s Forgotten History: Russian Literature, Japanese Mediation, and the Formation of Modern Korean Literature” by Heekyoung Cho, UW assistant professor of Asian languages and literature, explores the role of translation in the making of modern literature, and how its understanding changes when viewed through the lens of translation.

US-India collaboration finds molecular signatures of severe malaria

Malaria parasites infecting a red blood cell.

The malaria parasite can cause unusually severe cases of the eponymous disease in patients, leading to higher mortality and poorer health outcomes among survivors. But scientists have long struggled to understand why some patients develop severe malaria. The University of Washington’s International Center of Excellence for Malaria Research in South Asia — along with partners at the Center for Infectious Disease Research (CIDR) and Goa Medical College (GMC) of India — have discovered that specific types of parasite proteins, when…

UW researchers unleash graphene ‘tiger’ for more efficient optoelectronics

In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber’s energy gap, transferring just a small portion of light energy into electricity. The remaining energy is lost as heat. But in a paper released May 13 in Science Advances, Wu, UW associate professor Xiaodong Xu and colleagues at four other institutions describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.

UW study: state-licensed marijuana canopy enough to satisfy recreational and medical markets

The amount of marijuana allowed to be grown by state-licensed producers in Washington is enough to satisfy both the medical and recreational marijuana markets, a University of Washington study released today finds. The state Liquor and Cannabis Board (LCB) tasked the UW-based Cannabis Law and Policy Project (CLPP) with calculating the “grow canopy,” or square footage, required to supply the state’s medical marijuana market as it becomes folded into the state’s retail system, as required by the 2015 Cannabis Patient…

University of Washington students, faculty and staff are part of the fifth West Coast Ocean Acidification Cruise that will investigate changes to ocean chemistry from Baja to British Columbia. The ship left Thursday from San Diego to begin sampling on Mexico’s northern coast. It will stop May 21 at San Francisco’s Exploratorium Pier, then travel as far as northern Vancouver Island before ending in Seattle in early June. Follow along with the blog, which is being coordinated from shore by…

Brain pattern predicts how fast an adult learns a new language

Some adults learn a second language better than others, and their secret may involve the rhythms of activity in their brains. New findings by scientists at the University of Washington demonstrate that a five-minute measurement of resting-state brain activity predicted how quickly adults learned a second language. The study, published in the June-July issue of the journal Brain and Language, is the first to use patterns of resting-state brain rhythms to predict subsequent language learning rate. “We’ve found that a…

Early Earth’s air weighed less than half of today’s atmosphere

swirly rocks

The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles trapped in 2.7 billion-year-old rocks to show that air at that time exerted at most half the pressure of today’s atmosphere. The results, published online May 9 in Nature Geoscience, reverse the commonly accepted idea that the early Earth had a thicker atmosphere to compensate for weaker sunlight. The finding also has implications for which gases…

Music improves baby brain responses to music and speech

Rock your baby in sync with music and you may wonder how the experience affects her and her developing brain. A new study by scientists at the University of Washington’s Institute for Learning & Brain Sciences (I-LABS) shows that a series of play sessions with music improved 9-month-old babies’ brain processing of both music and new speech sounds. “Our study is the first in young babies to suggest that experiencing a rhythmic pattern in music can also improve the ability…

‘Shakespeare, Music, and Memory’ April 29 is colloquium, concert

Performers in UW Collegium Musicum rehearse for their concert April 29 concluding the colloquium "Shakespeare, Music, and Memory." From left are Linda Tsatsanis and Emerald Lessley, sopranos; John Lenti on baroque guitar and lute and Nathan Whittaker on baroque cello.

A daylong colloquium, “Shakespeare, Music and Memory” will bring scholars and musicians to the University of Washington campus April 29 for lectures ending with a concert of Shakespeare-themed songs by the School of Music’s Collegium Musicum ensemble. The free events were organized by JoAnn Taricani, associate professor and chair of the School of Music‘s Division of Music History, are timed to commemorate the 400th anniversary of William Shakespeare‘s death in April of 1616. Scholars from several universities will give presentations…

States with punitive justice systems have higher rates of foster care, study finds

The number of children in foster care across the country is driven not solely by child abuse and neglect, but by states’ varying politics and approaches to social problems, a new University of Washington study finds. States with more punitive criminal justice systems tend to remove children from their homes far more frequently than those with generous welfare programs – meaning that two states with similar rates of child abuse and neglect could have very different rates of foster care…

UW to study link between recession-related stress and health in older Americans

The Great Recession devastated millions of Americans financially — but what impacts did that economic stress have on their physical and mental well-being? Gillian Marshall, an assistant professor of social work at the University of Washington Tacoma, wants to answer that question. Marshall was awarded a five-year, $654,000 grant from the National Institutes of Health to study the link between financial hardship and health. She is the first faculty member at UW Tacoma to receive an NIH Mentored Research Scientist…

Scientists crack secrets of the monarch butterfly’s internal compass

Monarch butterflies.

Each fall, monarch butterflies across Canada and the United States turn their orange, black and white-mottled wings toward the Rio Grande and migrate over 2,000 miles to the relative warmth of central Mexico. This journey, repeated instinctively by generations of monarchs, continues even as monarch numbers have plummeted due to loss of their sole larval food source — milkweed. But amid this sad news, a research team believes they have cracked the secret of the internal, genetically encoded compass that the…
