New evidence indicates Four Corners Puebloans migrated far south after 1300
New evidence indicates while many Pueblo groups that abandoned the Four Corners area about 1300 migrated south to settle in northern Arizona and northern New Mexico, others made a swift, southernly migration up to 250 miles long.

Genome sequencing sheds light on bacterium harmful to newborns
Scientists completed sequencing the genome of Ureaplasma urealyticum, a sexually transmitted bacterium commonly found in adults but, if passed on to newborn infants, can cause in them meningitis, pneumonia, and even death.

The human side of restoring nature
Environmental restoration is about more than plants and animals. In a newly released book, Restoring Nature: Perspectives from the Social Sciences and Humanities, researchers explore the realm of human-nature interactions, of differing values and understandings about nature, and how that information can be effectively used to guide science and policy.

T.rex is more common than people thought
An American palaeontologist's discovery of five new T. rex skeletons in one season could put an end to the spiralling fossil prices that museums and collectors have seen recently.

UI researchers develop test indicating cystic fibrosis lungs are infected with bacterial biofilms
A laboratory test developed by University of Iowa researchers indicates that the lungs of cystic fibrosis (CF) patients are infected primarily with bacterial biofilms, organized communities of bacterial cells that are extremely resistant to antibiotic treatment.

Psychological and emotional studies of Mir missions show Russians fared better than Americans
American astronauts and mission control personnel who participated in the Mir space station missions tended to be less happy and less satisfied with their working conditions than their Russian counterparts, according to a study conducted by University of California, San Francisco researchers at the San Francisco Veterans Administration Medical Center.

The question of whether too much iron increases the risk of dying from heart disease has received another

New space views of Southeast Asian floods aid United Nations disaster relief efforts
Disaster relief agencies dealing with the worst flooding along the Mekong River since 1961 are getting help from a new global flood monitoring system developed by researchers at Dartmouth College.

Global capital mobility stifles union organizing
International trade and investment policies, combined with ineffective labor laws, have created a climate that has emboldened employers to threaten to close, or actually close, their plants to avoid unionization, a study by Cornell ILR faculty member Kate Bronfenbrenner's Labor Education Research Group shows.

Building bulkier smooth muscle cells through endoreduplication
In normal aging, unusually large smooth muscle cells accumulate in the walls of the aorta.

Antimatter could carry us to the edge of the solar system
An antimatter-aided space drive might bring deep-space missions within our grasp.

Gene barrier in corn may boost trade, environment
Working with teosinte, a wild cousin of maize, a University of Wisconsin-Madison scientist has found a molecular barrier that, bred into modern hybrid corn, is capable of completely locking out foreign genes, including those from genetically modified corn.

Donald Kennedy leads Science into the 21st century
Deciphering the human genome has been hailed as one of the greatest scientific achievements in history.

Measuring the tiniest of structures: researchers compare bending strength of individual carbon nanotubes
Researchers at the Georgia Institute of Technology have used a straightforward technique based on mechanical resonance induced by an oscillating electrical voltage to measure the comparative bending strength of tiny carbon nanotubes produced by two competing processes.

University of Georgia geneticist among the first to study genetic mating systems of fishes and turtles
A team of geneticists at the University of Georgia has published a series of research papers that is altering how science views the diverse reproductive strategies of some of nature's most interesting creatures.

Estrogen therapy may help prevent memory decline in elderly women
Normal aging in women affects their capacity for learning - coding, consolidating, and retrieving new information.

Students demonstrate water quality tests
Lettuce seeds and onion bulbs are two of the ingredients that will be used by high school students demonstrating simple water quality tests at the Education Training Fair this week at Montreal's Place Bonaventure.

Environment contributes to drug tolerance
The setting in which drugs are taken can be as big a contributor to developing a tolerance as the drugs themselves.

Three high schools - one in Huntsville and two in neighboring cities - will participate in a national engineering competition to build robots with the help of NASA's Marshall Space Flight Center in Huntsville, Ala.

How streptococci go for the throat
Pathogenic bacteria, like viruses, are accomplished molecular mimics, deploying surface molecules that interact with host- borne proteins in much the same way that endogenous host molecules do.

Golgi lipids regulate protein trafficking
Cells rely on the Golgi apparatus to sort secreted proteins bound for different intracellular destinations.

Economist says growth slows, remains strong, trouble looms
Despite slowing growth, the short-term U.S. economic outlook remains superb, and the nation will lead the world to new economic records this year, a University of North Carolina at Chapel Hill financial expert says.

Hopkins researchers uncover sinus infection-CF gene link
Scientists at Johns Hopkins report that some people who suffer with repeated sinus infections may be predisposed to them in part because they carry the same genetic mutation responsible for cystic fibrosis(CF).
