UW researchers illuminate ways to heal defects in solar cells

Electrical energy fuels our modern lives, from the computer screen that keeps us up after sunset to the coffee maker that greets us at sunrise. But the electricity underlying our 21st century world, by and large, is generated at a cost — through the unsustainable expenditure of fossil fuels. For decades this demand for cheap, fast and non-renewable electricity has promoted pollution and global warming. The key to reversing this downward spiral is deleting the “non” in “non-renewable electricity.” In…

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.

Scientists crack secrets of the monarch butterfly’s internal compass

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…

The Twittersphere does listen to the voice of reason — sometimes

In the maelstrom of information, opinion and conjecture that is Twitter, the voice of truth and reason does occasionally prevail, according to a new study from UW researchers. Tweets from “official accounts” — the government agencies, emergency responders, media or companies at the center of a fast-moving story — can slow the spread of rumors on Twitter and correct misinformation that’s taken on a life of its own.

Stir no more: UW scientists show that draining speeds up bioassays

HeLa cells stained with an antibody against beta-tubulin.

Three scientists at the University of Washington have proposed a way to speed up common bioassays used in research and diagnostics. Their solution, reminiscent of the magic behind washing machines, could reduce wait times to a fraction of what they once were. As they report in the journal Small, biological assays that once took hours could instead take minutes.
