The research identified a link between increased redemption rates and lower risk of discontinuation, with fruits, vegetables, eggs, and whole milk being key categories.
Researchers trained AI systems on data from two cultural groups playing a video game, finding that the agents learned and applied the group's degree of altruism. This approach, called inverse reinforcement learning, more closely aligns with human development and learning, where values are 'caught' rather than 'taught'.

Insect pollinators like bees and butterflies require more natural habitat with diverse flora to thrive, according to a new study analyzing over 178,000 individual pollinators from 19 countries. The research found minimum habitat requirements vary between species, ranging from 6% for hoverflies to 37% for butterflies.
Researchers tested a popular evolutionary theory by comparing maternal length and fetal sex in over 100,000 whales. They found that the fetal sex ratio skews female for longer body size, suggesting that female calves benefit more from heritable fitness than males do. The findings contradict the Trivers-Willard hypothesis.

In contrast, institutions in more progressive states often cited social justice arguments and framed their decisions around fairness and inclusion. These findings offer valuable lessons on how o...
The tech industry's shift to mass layoffs is causing disillusionment among employees, with many feeling a sense of 'cruel optimism' as companies prioritize profits over workers' well-being. Researchers have found that the layoffs are often unceremonious and may be intended to reset labor relations in favor of employers.
Researchers have designed a headphone system that translates several speakers simultaneously, preserving voice direction and qualities. The Spatial Speech Translation system uses off-the-shelf noise-cancelling headphones fitted with microphones to separate out different speakers in a space and translate their speech.

The team tested the system in Seattle and found a significant correlation between close passes and other indicators of cycling risk. The system could support mapping or navigating cyclists on safer bike routes through cities.
A recent study published in JAMA Network Open has found a possible link between higher ozone levels in early childhood and an increased risk of developing asthma. Children exposed to higher ozone levels in their first two years of life were significantly more likely to be diagnosed with asthma or wheezing at ages 4-6, but not at ages 8-9.

The Washington State Food Security Survey shows that food insecurity is widespread in the state, with rising grocery prices and expiring pandemic-era assistance programs exacerbating economic pressures. Key findings include higher rates of food insecurity among households with children and those earning $75,000–$150,000.
A team of researchers at the University of Washington has developed a novel method for 3D printing objects using a mixture of coffee grounds, brown rice flour, and Reishi mushroom spores. The resulting material is compostable, lightweight, and strong, with a density similar to that of polystyrene foam.
Research by University of Washington oceanographers found that whale excrement contains significant amounts of iron, a vital element for phytoplankton growth. The study suggests that the decimation of baleen whale populations may have had larger biogeochemical implications for the Southern Ocean ecosystem.
Baleen whale species that flee from killer whales produce calls at deep frequencies undetectable to their predators, while others sing higher-frequency songs that are easily heard. This 'flight' vs 'fight' difference influences all aspects of baleen whale behavior, from migration patterns and communication to mating and feeding habits.
A recent University of Washington study found that a slower increase in atmospheric carbon dioxide levels has less impact on the Atlantic Ocean's circulation. The research, published in PNAS, suggests that this slowdown allows the ocean system more time to adapt to rising CO2 levels and mitigates its effects.
The Hubble Space Telescope has captured a panoramic view of the Andromeda Galaxy, unveiling hundreds of millions of stars and providing new clues to its evolutionary history. The galaxy's unique structural features, such as coherent streams of stars, suggest a more active recent star formation and interaction history than the Milky Way.
Researchers at University of Washington developed IRIS, a smart ring that allows users to control smart devices by aiming the ring's small camera at the device and clicking a built-in button. The prototype Bluetooth ring controls devices up to two seconds faster than voice commands.
