Having a companion in old age is good for people — and, it turns out, might extend the chance for life on certain Earth-sized planets in the cosmos as well.
Planets cool as they age. Over time their molten cores solidify and inner heat-generating activity dwindles, becoming less able to keep the world habitable by regulating carbon dioxide to prevent runaway heating or cooling. (more…)
Soon, protection from HIV infection could be as simple as inserting a medicated, disappearing fabric minutes before having sex.
University of Washington bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV. Their method spins the drug into silk-like fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials such as gels or creams.

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. (more…)
There is no cure for Alzheimer’s disease and other forms of dementia, but the research community is one step closer to finding treatment.
University of Washington bioengineers have designed a peptide structure that can stop the harmful changes of the body’s normal proteins into a state that’s linked to widespread diseases such as Alzheimer’s, Parkinson’s, heart disease, Type 2 diabetes and Lou Gehrig’s disease. The synthetic molecule blocks these proteins as they shift from their normal state into an abnormally folded form by targeting a toxic intermediate phase. (more…)
Karen Litfin is a University of Washington associate professor of political science and author of the book “Ecovillages: Lessons for Sustainable Community.” She answered a few questions about the book, and her work, for UW Today.
Q: What is the main message of “Ecovillages”?
A: After teaching global environmental politics for two decades and watching planetary conditions deteriorate, I grew disenchanted with top-down solutions. I also grew tired of making my students anxious, depressed and guilt-ridden. If our ways of living are unraveling planetary life-support systems, then we must answer the question: How, then, shall we live? (more…)
The area of the brain that plays a primary role in emotional learning and the acquisition of fear – the amygdala – may hold the key to who is most vulnerable to post-traumatic stress disorder.
Researchers at the University of Washington, Boston Children’s Hospital, Harvard Medical School and Boston University collaborated on a unique opportunity to study whether patterns of brain activity predict teenagers’ response to a terrorist attack. (more…)
Your eye could someday house its own high-tech information center, tracking important changes and letting you know when it’s time to see an eye doctor.
University of Washington engineers have designed a low-power sensor that could be placed permanently in a person’s eye to track hard-to-measure changes in eye pressure. The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves. (more…)
In his new book, “Get a Job: Labor Markets, Economic Opportunity, and Crime,” University of Washington sociologist Robert Crutchfield takes on the popular notion that the unemployed are more likely to commit crimes. A former juvenile probation officer and parole agent, Crutchfield explains the nuanced links between work, unemployment and crime.
Q. You write that the stratification of labor contributes significantly to a person’s lifestyle and whether or not they commit crimes. Can you explain?
A. When someone has a low-end job (what some scholars refer to as secondary sector jobs), such jobs don’t pay well, and have few or no benefits and limited prospects for the future. Young adults in that situation may feel like they don’t have to conform to society’s expectations, and are at risk of getting involved in crime because they are likely to spend time with similar young men. People with good jobs, what some scholars call primary sector jobs, by contrast have something to lose if they do not constrain their own lifestyles. So they spend less time in situations where crime might occur. The stratification of labor that I write about is the structuring of the labor market into primary sector (good) jobs and secondary sector (bad) jobs. (more…)
