Auditory cues can influence hormone release and gonad growth in songbirds, but how the brain translates sounds into hormonal and behavioral signals has been a mystery. Now there's evidence a third form of a key reproduction hormone could link song and enhanced songbird procreation.
Large, deep earthquakes have shaken the central Puget Sound region several times in the last century, and less-powerful deep quakes have happened even more often. New research suggests these temblors' magnitude might depend on just where beneath the surface they occur.
Experiments with monkeyflowers add to the debate over what causes one species to become two: Does it take a hundred small genetic changes, each with mounting effect, or does speciation get kick-started by a few mutations that cause large effects?
Just in time for Halloween, a new study of the use of virtual reality to treat spider phobia indicates that touching the fuzzy creepy-crawlers can make the therapy twice as effective.
Evidence has mounted for nearly 20 years that a great earthquake ripped the seafloor near the Washington coast in 1700, long before there were any written records in the region. Now, a newly authenticated record of a fatal shipwreck in Japan has added an intriguing clue.
A University of Washington paleontologist theorizes that low oxygen and repeated short but substantial temperature increases because of greenhouse warming sparked two major mass-extinction events, one of which eradicated 90 percent of all species on Earth.

The imprisonment of more than 117,000 Americans of Japanese ancestry was no spur-of-the-moment decision launched in response to the Dec. 7, 1941, attack on Pearl Harbor. Rather it was the end game in a long, deliberate process undertaken by the United States government.
Conventional wisdom says a river's flood plain builds bit by bit, flood after flood, whenever the stream overflows its banks and deposits new sediment on the flood plain. But for some vast waterways in South America's Amazon River basin, that wisdom doesn't hold water.
Considering the cost of wildfires against the cost of thinning overly dense stands in two national forests in Washington and Oregon has implications for forests across the Intermountain West, from Canada to Arizona and New Mexico.
A 50,000-year record of mammals consumed by early humans in southwestern France indicates there was no major differences in the prey hunted by Neanderthals and Cro-Magnon, countering the idea that Cro-Magnon supplanted Neanderthals because of some evolutionary physical or mental advantage.
Richard L. Nolan, professor emeritus of The Harvard Business School, will be named on Monday the inaugural Philip M. Condit Endowed Chair in Business Administration at the University of Washington Business School.

Nine out of 10 urban school superintendents say they need more authority to fix bad schools and boost student achievement, according to a survey of the superintendents of the nation's 100 largest districts.
The staying power of seafloor hydrothermal vent systems like the bizarre Lost City vent field is one reason they also may have been incubators of Earth's earliest life.
The group that proposed creating a National Underground Science and Engineering Laboratory at a closed South Dakota gold mine has completed a detailed engineering plan for the conversion.
Social interaction apprently plays a far more important role in how infants learn language than previously believe, according to three related studies.
Given only a fraction of a second to respond to images of men popping out from behind a garbage dumpster, people were more likely to shoot blacks than whites, even when the men were holding a harmless object such as a flashlight rather than a gun.
Through many decades, stories about earthquakes raising or lowering water levels in wells, lakes and streams have become the stuff of folklore. But the relationship between seismic activity and hydrology is not well understood and is ripe for serious examination by scientists from the two disciplines, said a University of Washington hydrologist.
Invisible and unfelt by anyone at the surface, the energy from internal waves appears to be crucial to the conveyor-belt-like circulation wherein cold water sinks at high latitudes and is driven to upwell at lower latitudes.
It's getting harder and harder for the few remaining residents of the Aleutian and Pribilof islands who speak Aleut to hold a conversation. Only about 100 people still speak the native Alaskan language. However, a new effort to save Aleut by recording and videotaping the language will begin this year.
Social-welfare programs may help many more people than previously thought, an economist has found.
Forty university architecture students soon will head to Montana to help the Northern Cheyenne tribe build a house out of straw. The June 29-July 11 "build" will make use of techniques developed at the University of Washington and Pennsylvania State University.
School districts transfer millions of dollars each year from schools in poor neighborhoods to those with wealthier students and higher-paid teachers. The new study documents the effects of a system used by nearly all urban school districts, which allocate money as if all teachers made the same salary even though better-paid teachers cluster in affluent neighborhoods.
Atmospheric aerosols, airborne particles that reflect the sun's heat away from Earth and into space, are part of everyday life. But a new study says the cooling effect of man-made aerosols could throw a monkey wrench into the current understanding of climate change.
Murder often begins at a terrifyingly young age. It is an awful journey-- frequently launched by physical and sexual violence, bullying and neglect -- that terminated in 1997 with the execution of 37 convicted Texas men.
Researchers found that an unmarried mother is 42 percent more likely to marry the father if the child is a boy.
What may be the nation's first university graduate course on Information In Sports is quietly introducing 30 future librarians this spring to, among other things, the infield fly rule.
Researchers discovered that a group of aerospace engineers usually chose human sources over written ones and were three times more likely to choose familiar people over experts they didn't know.
The bizarre Lost City hydrothermal vent field surprised scientists with vents that are the tallest ever seen -- the one that's 18 stories dwarfs most vents at other sites. The first U.S. scientific expedition to the site since its discovery leaves April 21.
A woman's heavy episodic drinking during pregnancy triples the odds that her child will develop alcohol-related problem at age 21, according to a new study that has been tracking young adults since before their birth.
Experiment results from the Thomas Jefferson National Accelerator Facility undo the long-held notion that a proton is shaped like a sphere, a University of Washington physicist has found.
Children whose mothers are the most depressed, anxious and report high levels of psychosomatic symptoms are twice as likely to be taken to a doctor when they complain of a stomache ache than are children whose mothers report the least amount of such mental stress.

Archaeologists have uncovered another piece of evidence that seems to exonerate some of the earliest humans in North America of charges of exterminating 35 genera of Pleistocene epoch mammals.
Researchers have found a way to reverse what appears to be a universal decline in foreign language speech perception that begins toward the end of the first year. Nine-month-old American infants who were exposed to Mandarin Chinese for less than five hours in a laboratory setting were able to distinguish phonetic elements of that language.
University of Washington professors can help reporters with stories on terrorism and conflicts involving Iraq and North Korea.
