Vast amounts of dissolved organic matter in the ocean, once thought to be inert, may play a surprising role in mitigating the greenhouse effect, according to bioengineering researchers at the University of Washington, reporting in this week's (Feb. 5) issue of Nature.
In the first long-term study of mathematically precocious young children, University of Washington researchers have found significantly more boys than girls with very high levels of math talents, and discovered that even when children are given an enrichment program math-talented girls don't catch up with boys in the first two years of school.
If Paul Simon had been a social scientist instead of a song writer he might have stopped counting those "50 Ways to Leave Your Lover" and focused on finding ways to keep his lover around. The result might have been like "The Love Test," a new book filled with 32 romance and relationship-oriented quizzes that has been compiled by two University of Washington sociologists.
Adults may have abandoned the pen for the keyboard, but until first-graders have laptops, it's crucial that children continue to be taught handwriting because of its link to composition. A University ofWashington study of children with writing problems shows that first-graders improved both their handwriting and their composition after being tutored.
Health related pledges are the most common form of New Year's resolutions and researchers have found that a person's confidence that he or she can make a behavior change and the commitment to making that change are the keys to achieving resolutions.
The flight of a balloon sent aloft by scientists over Kiruna, Sweden, seemed uneventful -- until researchers started examining the data. What was found by three graduate students has scientists scrambling for an explanation: an intense stream of X-rays, occurring in seven bursts, each separated by only a few minutes and lasting for a total of half an hour. The evidence is that the bursts came not from space, but from the Earth's upper atmosphere.
It seems that Americans are not entirely to blame for the chemical smog that hangs over cities along the U.S. West Coast. A new study indicates that about 10 percent of the ozone and other pollutants are arriving from the industrialized nations of East Asia. After measuring pollutants from a remote Olympic Peninsula research station, a researcher concludes that Asian pollution is affecting much of the U.S.West Coast, with Washington and Oregon affected slightly more because of wind patterns.
Last May University of Iowa space physicist Louis Frank claimed to have discovered 20- to 40-ton cosmic snowballs, the size of houses, pelting the Earth at the rate of 30,000 a day. Now University of Washington geophysicist George Parks has analyzed Frank's ultraviolet (UV) camera images and has concluded that the white snow in space is no more than black "snow" on the television screen. Parks and his collaborators are certain that Frank has been looking at "instrument noise."
As millions of students are about to rate the teaching abilities of their professor, researchers say such evaluations are flawed and often misused. Science, math and engineering instructors, who teach demanding classes, are often penalized with undeservedly low ratings, while teachers of easier courses are often rewarded with unfairly high ratings.
Individual brain cells continually perfrom complex computational tasks to help humans, bats, gerbil, birds and other creatures distinguish what a sound ;is and where it is coming from. To do this, individual neurons do not just relay information from one point to another. Instead each neuron could be compared to a tiny computer that compiles ;information from many sources and makes a decision based on that information, say a group of neuroscientists who are beginning to unravel how brain cells continually perform complex computations what a sound is and where it's coming from.
The picture of life on the streets for children in the late 20th century drawn from a University of Washington psychologist is a horrifying one. Violence in ;the form of physical and sexual abuse are rampant, as are suicide attempts, mental and emotional disorders, and drug and alcohol abuse. But those conditions may be an improvement over those found at home.
Surgical students soon will be able hone their skills with simulators that for the first time present a realistic feel of performing surgery thanks to a research project under way at the University of Washington. The project also could improve patient care by leading to the development of instruments that enhance surgeons' sense of touch.
The proposition that the Earth's little understood inner core is a frozen yet white hot globe of curiously laid out iron crystals, spinning independently of the rest of the planet, is confirmed by University of Washington geophysicist Kenneth Creager in tomorrow's Science.
The National Science Foundation has appointed University of Washington Professor Mark Haselkorn to coordinate its external efforts to address the year 2000 computer problem.
A supercomputer is ushering in a new era of high-precision weather forecasting. The University of Washington has switched on the latest version of its MM5 weather forecasting system, the world's first to diagnose and forecast local weather on a scale of a few thousand yards. The four-kilometer system can follow a region's topography so accurately that it can "see" rain showers on one side of a mountain and the rain shadow on the other.
Stumps of cedar trees are revealing details of a huge earthquake along North America's west coast more than 100 years before the arrival of the first European occupants. University of Washington researchers are reporting in Nature that evidence in the dead wood confirms that a great earthquake struck the Pacific Northwest coast in 1700 and set off a tsunami, a train of massive ocean waves, that flooded coastal Japan.
A new study of genetically normal rats indicates that the effects of overfeeding extends for at least three generations and may explain health trends beginning to be seen in human populations around the world, a University of Washington researcher told the Society of Neuroscience today.
A new study indicating that portions of bird brains enlarge in response to social factors adds to the mounting evidence that the brains of higher animals change over time. A University of Washington researcher reported that parts of the brains of male sparrows housed with females enlarged 15 to 20 percent larger than brains of other birds housed with males or in isolation
It looks like El NiÃ’o, it feels like El NiÃ’o, and if you are watching fish stocks or reservoir levels you would say it is El NiÃ’o. But it isn't. Researchers at the University of Washington are describing a decades-long climate shift, called the Pacific Decadal Oscillation, that seems to explain many of the changing environmental patterns seen across North America since the late 1970s, from disappearing salmon along the West Coast to wetter than average winters in the South.
University of Washington researchers will play a leading role in a $20 million effort to identify and mitigate potential earthquake hazards in urban areas along the Pacific coast. The UW joins eight California universities in the Pacific Earthquake Engineering Research Center announced today by the National Science Foundation.
The earliest existing mound complex built by humans in the new world has been identified in Louisiana by a team of archaeologists and researchers from around the United States. Details of the discovery appear in tomorrowÃs (Sept. 19) issue of the journal Science. The complex of 11 mounds was built between 5,000 and 5,400 years ago and predates other known existent mound complexes by 1,900 years.
A new form of matter, clusters of atoms, has been found to have a previously unsuspected property: it can melt at different temperatures from "solid" matter. An experiment described in Science this week paints an exotic portrait of certain substances seemingly confounding nature by existing as a liquid, instead of a solid, at room temperature.
Extinct sea creatures have provided evidence that about 80 million years ago the west began to wander. University of Washington paleontologist Peter Ward and his collaborators report in Science that the discovery of pearly fossil shells of ammonites on two islands off the coast of Vancouver Island indicate that British Columbia and southern Alaska were once where Baja California is today.
Doctors needing chemical analyses such as blood tests to make life-saving diagnosis and treatment decisions soon won't have to lose precious time waiting for results to come back from the lab. New hand-held sensor technology developed at the University of Washington will allow physicians to bring a sophisticated "laboratory" directly to their patients for instant, on-site chemical analysis.
While there is never a good time to acquire a herpes infection, contracting the virus late in pregnancy can prove catastrophic for the newborn child, with a high risk of severe brain damage or death from neonatal herpes.
