Single-celled organisms in the open ocean use a diverse array of genetic tools to detect light, even in tiny amounts, and respond. The discovery of these new genetic "light switches" could also aid in the field of optogenetics, in which a cell's function can be controlled with exposure to light.
Bleeding of the gums on gentle probing, or gingival bleeding tendency, and also bleeding in the eye, or retinal hemorrhaging, were associated with low vitamin C levels in the bloodstream.
A new University of Washington paper published Jan. 11 in Nature Sustainability 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. Scientists observed these oscillations in urban and rural settings — regardless of an individual’s access to electricity.
A University of Washington-led team has revisited and comprehensively reinterpreted radio telescope observations underlying a 2019 claim of phosphine in the atmosphere of Venus. They report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.
The study, which followed 240 pregnant women between March and June 2020, found that the COVID-19 mortality rate in the pregnant women was significantly higher when compared to the COVID-19 mortality rate in similarly aged individuals within Washington state.
A University of Washington 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.
University of Washington researchers developed a technique to modify naturally occurring biological polymers with protein-based biochemical messages to affect cell behavior. Their approach uses near-infrared lasers to trigger chemical adhesion of proteins to scaffolds made from biological polymers like collagen.
If pregnant individuals catch COVID they will generally get sicker than non-pregnant individuals. They also more commonly end up on ECMO [heart-lung support], in the ICU or on ventilators.
Even people who have experienced severe allergic reactions to food, latex, pets, pollen, or bee stings should get the coronavirus vaccine, UW Medicine allergy and infectious disease experts say.
Astronomers have catalogued 126 years of changes to HS Hydrae, a rare evolving eclipsing binary. 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 Feb. 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.
University of Washington researchers helped six Seattle-area people with spinal cord injuries regain some hand and arm mobility.
Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability.
A University of Washington-led team has come up with a system that could help speed up AI performance and find ways to reduce its energy consumption: an optical computing core prototype that uses phase-change material.
Diabetes continues to be the leading cause of new cases of blindness among adults in the United States. But the current shortage of eye-care providers would make it impossible to keep up with demand to provide the requisite annual screenings for this population. A new study looks at the effectiveness of seven artificial intelligence-based screening algorithms to diagnose diabetic retinopathy, the most common diabetic eye disease leading to vision loss.
New epidemiological and neuroscientific evidence suggests emotional pain activates many of the same limbic brain centers as physical pain. Pain experts Mark Sullivan and Jane Ballantyne at the University of Washington School of Medicine explain the relation in a reflections column published ahead of print in the Annals of Family Medicine. The researchers say opioids may make patients feel better early on, but over the long term these drugs cause all kinds of havoc on their well-being.
A little slice of life at a vaccination clinic at UW Medicine in Seattle.
A team of Ghanaian and U.S. researchers examined whether having insurance affected trauma patients’ out-of-pocket costs and their chances to get timely surgical care after being admitted to Komfo Anokye Teaching Hospital, a large teaching hospital in Kumasi, Ghana, a city of 3.3 million. The study was published in the Bulletin of the World Health Organization. Collaborators came from Stanford University and the University of Utah.
The SARS-CoV-2 virus, like many viruses before it, is bad news for the brain. In a study published Dec.16 in Nature Neuroscience, researchers found that the spike protein, often depicted as the red arms of the virus, can cross the blood-brain barrier in mice. This strongly suggests that SARS-CoV-2, the cause of COVID-19, can enter the brain. The spike protein, often called the S1 protein, dictates which cells the virus can enter. Usually, the virus does the same thing as its binding protein, said lead author William A. Banks, a professor of medicine at the University of Washington School of Medicine and a Puget Sound Veterans Affairs Healthcare System physician and researcher. Banks said binding proteins like S1 usually by themselves cause damage as they detach from the virus and cause inflammation.
A model based solely on the past 40 years of weather events uses 7,000 times less computer power than today’s weather forecasting tools. An A.I.-powered model could someday provide more accurate forecasts for rain, snow and other weather events.
New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. It provides a new picture of the circulation and climate of the North Pacific at the end of the last ice age, with implications for early human migration.
Antarctica’s 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’s coastline could provide clues to the most recent collapse of the West Antarctic Ice Sheet.
A University of Washington-led team 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 University of Washington study provides the first look at how much noise pollution is impacting the Olympic Peninsula in Washington state. 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 scientists at the University of Washington and the University of California, San Diego has discovered that cowpeas — a type of bean plant — harbor receptors on the surface of their cells that can detect a compound in caterpillar saliva and initiate anti-herbivore defenses.
Experts at the Center for Study of Health and Risk Behaviors at the University of Washington created a personalized assessment tool for young adults, including tips on how to increase their well-being during the pandemic.
Using images from the Hubble Space Telescope, astronomers have discovered that the Stingray Nebula, the youngest planetary nebula in our sky, has faded dramatically 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 team led by researchers at the University of Washington Tacoma, UW and Washington State University Puyallup have discovered a chemical that kills coho salmon in urban streams before the fish can spawn.
A new University of Washington study finds that Black youth are more likely than white youth to be treated as “usual suspects” 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.
A research team led by the University of Washington and Pacific Northwest National Laboratory has shown that microbes taken from trees growing beside pristine mountain-fed streams in Western Washington could make phosphorus trapped in soils more accessible to agricultural crops.
Specifically, Dr. Susan Reed talked about research into drugs that act at the kisspeptin/neurokinin B/ dynorphin (KNDy) neuron complex in the hypothalamus which controls reproduction and hormonal control. During menopause, estrogen levels decrease, which causes these neurons to be hyperstimulated, thereby causing hot flashes.
A bioethicist lays out the ethical rationale to develop robots for isolated and disabled older people – a population increasingly alone due to COVID-19. Many lonely seniors would value a robot for companionship and sexual gratification, writes Nancy Jecker at the Univ. of Washington School of Medicine.
University of Washington and Microsoft researchers have developed a DNA-based molecular tagging system.
Research shows that collaborative care programs in which primary-care providers work with a depression care manager and a designated psychiatric consultant can more than double the likelihood of improving depression outcomes. But a new study published in Health Affairs shows that not all care is equal.
The biggest study yet of West Coast wildfire plumes shows how a smoke plume’s chemistry changes over time. Results suggest current models may not accurately predict the air quality downwind of a wildfire.
A new study indicates that the earliest evidence of mammal social behavior goes back to the Age of Dinosaurs. A multituberculate that lived about 75.5 million years ago, Filikomys primaevus engaged in multi-generational, group-nesting and burrowing behavior, and possibly lived in colonies.
A research team led by UC Irvine and the University of Washington has created a new model of how the coronavirus can spread through a community. The model factors in network exposure — whom one interacts with — and demographics to simulate at a more detailed level both where and how quickly the coronavirus could spread through Seattle and 18 other major cities.
