Cambridge, Md. (March 11, 2010) – The increased frequency and intensity of oxygen-deprived "dead zones" along the world's coasts can negatively impact environmental conditions in far more than just local waters. In the March 12 edition of the journal Science, University of Maryland Center for Environmental Science oceanographer Dr.
The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms.
BUFFALO, N.Y. -- Since 2004, University at Buffalo anthropologist Ezra Zubrow has worked intensively with teams of scientists in the Arctic regions of St. James Bay, Quebec, northern Finland and Kamchatka to understand how humans living 4,000 to 6,000 years ago reacted to climate changes.
Their findings will tell governments, scientists and NGOs how relationships between human beings and their environments may change in decades to come as a result of global warming.
DALLAS (SMU) – A study of seismic activity near Dallas/Fort Worth International Airport by researchers from Southern Methodist University and the University of Texas at Austin reveals that the operation of a saltwater injection disposal well in the area was a "plausible cause" for the series of small earthquakes that occurred in the area between Oct. 30, 2008, and May 16, 2009.
Results of a clinical trial conducted in a largely self-contained religious community during the 2008-09 influenza season show that immunizing children against seasonal influenza can significantly protect unvaccinated community members against influenza as well. The study was conducted to determine if immunized children could act as a barrier to limit the spread of influenza to the wider, unvaccinated community, a concept known as herd immunity.
The extremely strong earthquake in Chile on 27 February this year was a complicated rupture process, as scientists from the GFZ German Research Centre for Geosciences found out. Quakes with such magnitude virtually penetrate the entire Earth's crust. After closer analysis of the seismic waves radiated by this earthquake during the first 134 seconds after start of the rupture, the researchers came to the conclusion that only the region around the actual epicentre was active during the first minutes. In the second minute the active zone moved north towards Santiago.
Palo Alto, CA— A new study by scientists at the Carnegie Institution finds that over a third of carbon dioxide emissions associated with consumption of goods and services in many developed countries are actually emitted outside their borders. Some countries, such as Switzerland, "outsource" over half of their carbon dioxide emissions, primarily to developing countries. The study finds that, per person, about 2.5 tons of carbon dioxide are consumed in the U.S. but produced somewhere else. For Europeans, the figure can exceed four tons per person.
COLUMBUS, Ohio – The massive magnitude 8.8 earthquake that struck the west coast of Chile last month moved the entire city of Concepcion at least 10 feet to the west, and shifted other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
Jerusalem, March 7, 2010 – Friction in physics has had a "secret life" of its own that has revealed new clues, say scientists at the Hebrew University of Jerusalem.
In an article appearing in the journal Nature (with a further reference to it in Nature Physics), the scientists show how frictional strength evolves from extremely short to long time scales. The new information could be useful in assessing a wide range of natural and man-made phenomena — from earthquakes to computer hard drives
VERNON -- The application of summer patch burning to heal native rangeland may be best accomplished using rotational grazing, according to a Texas AgriLife Research range ecologist.
Dr. Richard Teague recently completed a study of native rangeland vegetation and soils subjected to summer patch burns followed by cattle being allowed to graze either continuously or using a rotational grazing system.
Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time.
Funded by the National Science Foundation (NSF) and led by scientists at Harvard University, the team reports on its work this week in the journal Science.
The new findings--based on an analysis of ancient tropical rocks that are now found in remote northwestern Canada--bolster the theory that our planet has, at times in the past, been ice-covered at all latitudes.
Ten Kent State University researchers are part of a team of international scientists who have discovered the most massive antinucleus discovered to date. They are part of an international team of scientists studying high-energy collision of gold ions at the Relativistic Heavy Ion Collidor (RHIC), a 2.4 mile-circumference particle accelerator at the U.S Department of Energy's Brookhaven National Laboratory in Upton, N.Y.
A worldwide team of researchers, including 10 from Texas A&M University, have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe – the so-called "Big Bang" – and it could lead to new questions and answers about some of the basic laws of physics because in essence, it creates a new form of matter.
USGS scientists are helping Haitians lay the groundwork for reconstruction and long-term earthquake monitoring in the wake of the Jan. 12, 2010, magnitude-7 earthquake, by providing geologic research that will assist with the establishment of new building codes in the country.
"USGS research will contribute to explicit recommendations to both the Haitian government and the international community that is assisting the reconstruction efforts," said Walter Mooney, USGS research geophysicist, who recently returned from Haiti.
