Glacial Pace Of Erosion Was Not So Slow, New Technique Shows
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work. Globalization: Diseases Spreading From Humans To Animals, Study Finds
Globalization and industrialization are causing diseases to spread from humans to animals, a study has shown. Researchers have shown that a strain of bacteria has jumped from humans to chickens. Quick Sniff To Clear Migraine Headaches?
Relief from the pain, nausea and other awful symptoms of migraine could become just a sniff away, as researchers develop new drugs -- including an inhalable medication -- for a condition that affects an estimated 30 million people in the United States, according to a new article. The potential new migraine medications may be safer and more effective than existing drugs. High Risk Of Major Tsunami In Northern Caribbean: Over 35 Million Coul
The potential for devastating tsunamis in the northern Caribbean is high, say marine scientists, based on their analysis of historical data since the arrival of Columbus. Several natural phenomena could trigger giant tsunamis, they say, with effects felt in the islands of the Greater and Lesser Antilles and along the east and Gulf coasts of the United States. New Light On Early Formation Of Earth And Mars
Mars was covered in an ocean of molten rock for about 100 million years after the planet formed, according to new research. The finding indicates that the both Earth and Mars cooled slower than scientists thought and a mechanism to keep the planet interiors warm is required. Commission on the Intelligence Capabilities of the United States Regar
This commission established in February 2004 "is charged with assessing whether the Intelligence Community is sufficiently authorized ... to identify and warn in a timely manner of, and to support United States Government efforts to respond to ... the proliferation of Weapons of Mass Destruction [WMD]."The site features a FAQ, the commission's report submitted to the president on March 31, 2005, and related material. Team Creates Uncanny Cell Replicas for Treatment, Research
Is that Schwann cell real -- or replica? A Brown University biomedical engineer had a tough time telling apart genuine cells from fakes after casting plastic reproductions of these nervous system support cells out of silicon. The rubbery replicas, described in the journal Langmuir, could be used for all sorts of cell types in laboratory research or medical treatments for repairing nerve damage. Nanoengineered Concrete Could Cut Carbon Dioxide Emissions
While government leaders argue about the practicality of reducing world emissions of carbon dioxide, researchers are seeking ways to make it happen. One group of engineers at MIT is focusing its work on the nanostructure of concrete, the world's most widely used material. The production of cement, the primary component of concrete, accounts for 5 to 10 percent of the world's total carbon dioxide emissions; the process is an important contributor to global warming. How Do Newcomers Make Changes In Long-standing Groups?
Virtually everyone who joins a new group is sensitive to the fact that, as a newcomer, he or she must tread carefully for a while, keeping a low profile until becoming sufficiently integrated into the group. When they do offer their ideas, criticisms, and suggestions, existing group members typically resist their contributions. "Why does that happen and what can be done to overcome that resistance?"
