The atmosphere is warming faster around 30 degrees north and south latitude than elsewhere, new research shows. But scientists examining more than 25 years of satellite data also found that each hemisphere's jet stream has moved toward the pole by about 1 degree of latitude, which could widen the tropics and expand some of the world's driest regions.
At a time when some say privacy has gone the way of the Dodo bird, University of Washington researchers find evidence that a significant minority cling to an expectation of privacy even in public places. They also found a marked difference in views depending on gender.

Multiracial adolescents in middle school are significantly more likely to engage in problems behavior such as violence and substance use than are single-race young people.
When it comes to talking about suicide, American avoid the topic much the way they used to skirt talk about sex 20 years ago. But the president of the American Association of Suicidology says the time is long overdue for people to start talking about the problem and to launch suicide awareness and prevention programs in the nation's schools.
New University of Washington research shows that a regulatory gene named broad, known to be necessary for development of insects that undergo complete metamorphosis, also is key for the maturation of insects that have incomplete metamorphosis.
University of Washington scientists have developed a screening process to detect enzyme deficiencies in newborns that could allow treatment of devastating conditions such as Tay-Sachs and Gaucher syndromes to begin before too much damage has been done.
If you think you've got a bad boss, one who loves to chew people out, or if you work with backstabbing co-workers, be thankful you are not a wasp. If you were, chances are your nestmates might bite you to communicate that it is time for you to leave the nest and forage for the colony.
With warming temperatures as the possible underlying cause, scientists wonder what is pushing Greenland's glaciers out to sea as much as 50 percent quicker than before. As a glacier's leading edge calves, openings may be created for ice to stream through, sort of like water through a break in a dike dam.
Scientists analyzing recent samples of comet dust have discovered minerals that formed near the sun or other stars. That means materials from the innermost part of the solar system could have traveled to the outer reaches, where comets formed.
Like an armada of small rototillers, female salmon can industriously churn up entire stream beds from end to end, sometimes more than once, using just their tails. A researcher says the silt, minerals and nutrients that are unleashed cause changes in rivers and lakes far from the nest building.
You can't always trust your eyes. Neuroscientists from the University of Washington and the University of Minnesota have found that the first area in the cortex of the human brain that receives information from the eyes processes the perceived size, rather than the actual size, of an object.
While biologists sort out what levels of noise go unnoticed, are annoying or cause harm to marine mammals, physical oceanographer Jeff Nystuen is giving scientists and managers a way to sift through and identify the sounds present in various marine ecosystems.
When fishing boats return with catches of increasingly less-valuable fish, the commonly held notion is that the more valuable species have been fished out. This, however, wasn't true in two-thirds of the world's large marine ecosystems selected for study by University of Washington researchers.

The authors of a paper in last week's Proceedings of the Royal Society of London Section B, who say their 7.9 mm-long fish from Southeast Asia is the smallest fish and vertebrate known, have failed to make note of work published last fall that describes a sexually mature, male anglerfish measuring 6.2 mm.
The ideal Valentine's Day present for people seeking their sweethearts might be a package of self-knowledge.
When Stardust's sample-return canister was opened, scientists were amazed by what they saw. Principal investigator Donald Brownlee of the University of Washington labeled the NASA mission "a phenomenal success."
