Current advice from the American Dental Association tells you that if your gums bleed, make sure you are brushing and flossing twice a day because it could be a sign of gingivitis, an early stage of periodontal disease. And that might be true. So if you are concerned, see your dentist. However, a new 糖心原创 study suggests you should also check your intake of vitamin C. 鈥淲hen you see your gums bleed, the first thing you should think…
A new 糖心原创 paper quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.
Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. The team, led by researchers at the 糖心原创, observed these variations in both the time of sleep onset and the duration of sleep in urban and rural settings 鈥� from Indigenous communities in northern Argentina to college students in Seattle, a city of more than 750,000. They saw the oscillations regardless of an individual鈥檚 access to electricity, though the variations are less pronounced in individuals living in urban environments.
As part of the Transportation Data Equity Initiative, the UW is developing technology that will allow underserved groups to use tools similar to Google Directions and OneBusyAway to get from place to place.
A 糖心原创-led team has revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.
A 糖心原创 study analyzes how a state’s refundable Earned Income Tax Credit can lead to fewer reports of child neglect, by reducing the financial stress on families.
A study accepted by the Planetary Science Journal shows that the planets of the TRAPPIST-1 system share similar densities. That could mean they all contain roughly the same ratio of materials thought to be common to rocky planets, such as iron, oxygen, magnesium and silicon — though they appear to differ notably from Earth.
Researchers at the 糖心原创 have developed a technique to modify naturally occurring biological polymers with protein-based biochemical messages that affect cell behavior. Their approach, published the week of Jan. 18 in the Proceedings of the National Academy of Sciences, uses a near-infrared laser to trigger chemical adhesion of protein messages to a scaffold made from biological polymers such as collagen, a connective tissue found throughout our bodies.
Astronomers have catalogued 126 years of changes to a binary star system called HS Hydrae. Analyzing observations from astro-photographic plates in the late 1800s to TESS observations in 2019, they show that the two stars in HS Hydrae began to eclipse each other starting around a century ago, peaking in the 1960s. The degree of eclipsing then plummeted over the course of just a half century, and will cease around February 2021.
A new UW study reveals people’s perceptions that sexual harassment primarily affects young, feminine and conventionally attractive women. Women who fall outside that prototype not only are perceived as unharmed by harassment, but also have a harder time convincing others that they have been harassed.
Using physical therapy combined with a noninvasive method of stimulating nerve cells in the spinal cord, 糖心原创 researchers helped six Seattle area participants regain some hand and arm mobility.

The first scheduled to receive vaccinations were frontline personnel working with COVID-19 patients. In addition to patient-care staff in intensive care units, COVID acute care floors and emergency departments, the immediate list also included environmental services staff, as well as emergency medical responders in the community. Next in line are nursing home residents and their caregivers.
A study co-authored by UW’s Sunny Jardine finds that farmed Atlantic salmon, often labeled and sold as Pacific salmon or rainbow trout, is the second-most-consumed mislabeled seafood product in the U.S. Although not the most frequently mislabeled seafood, salmon’s popularity means it has one of the biggest environmental impacts.

Antarctica鈥檚 next deep ice core, a 1.5-mile core reaching back to 130,000-year-old ice, will be carried out by a multi-institutional U.S. team led by UW’s Eric Steig. The site hundreds of miles from today鈥檚 coastline could provide clues to the most recent collapse of the West Antarctic Ice Sheet.
A team led by the UW has developed Smellicopter: an autonomous drone that uses a live antenna from a moth to navigate toward smells. Smellicopter can also sense and avoid obstacles as it travels through the air.
A new 糖心原创 study provides the first look at how much noise pollution is impacting the Olympic Peninsula. The paper found that aircraft were audible across a large swath of the peninsula at least 20% of weekday hours, or for about one hour during a six-hour period. About 88% of all audible aircraft in the pre-pandemic study were military planes.
A team led by researchers at UW Tacoma, UW and Washington State University Puyallup has discovered a chemical that kills coho salmon in urban streams before the fish can spawn.
The tiny Stingray Nebula unexpectedly appeared in the 1980s is by far the youngest planetary nebula in our sky. But a team of astronomers recently analyzed a more recent image of the nebula, taken in 2016 by Hubble, and found that it has faded significantly and changed shape over the course of just 20 years. If dimming continues at current rates, in 20 or 30 years the Stingray Nebula will be barely perceptible.
A new 糖心原创 study finds that Black youth are more likely than white youth to be treated as 鈥渦sual suspects鈥� after a first encounter with police, leading to subsequent arrests over time. Even as white young adults report engaging in significantly more illegal behavior, Black young adults face more criminal penalties.
