Big Bang Brings Big Prize
The work of two Americans didn't prove the "big bang" theory but certainly advanced the argument for it, prompting the chairman of the Nobel committee for physics to declare it "one of the greatest discoveries of the century." It also brought them the Nobel Prize for physics. Unique Database Mapping 'Expression'Of Genes In Brain Could Lead To Ne
A new database that could help scientists identify which proteins to target when developing treatments for neurological conditions such as Alzheimer's Disease has been established. The database maps all of the genes operating in one section of the brain, and their 'expression'-- the process of converting the genetic information encoded in DNA into a final gene product. How HIV Disables The Cells' Call For Help
The HIV virus hides out in the very immune system cells that are meant to protect the body from viral infection. But how does it prevent these cells from mounting a full-scale attack against the invader? In research published today in the Journal of Clinical Investigation, a team at the Weizmann Institute of Science has shown how a part of a protein on the virus -- outer surface interferes with the cells -- normal immune response. But their work may have wider implications. 'Cold Linac' Commissioning Major Step For ORNL's Spallation Neutron So
The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory has met a crucial milestone on its way to completion in June 2006 -- operation of the superconducting section of its linear accelerator. Researcher Placing Eye Implants In Cats To Help Humans See
In "Star Trek: The Next Generation,"Geordi La Forge is a blind character who can see through the assistance of special implants in his eyes. While the Star Trek character "lives"in the 24th century, people living in the 21st century may not have to wait that long for the illuminating technology. Low Cholesterol Levels Associated With Cancer, Study Finds
Millions of Americans take statins to lower their cholesterol, but how low should you go? Many scientific studies support the benefits of lowering low-density lipoprotein (LDL) cholesterol, and achieving low LDL cholesterol levels is one of the most important steps in preventing heart disease. New research, however, provides evidence for an association between low LDL levels and cancer risk. Survey of Mexican Migrants, Part Two: Attitudes About Voting in Mexica
This survey, released in March 2005, reports that of the "nearly 5,000 Mexican migrants who were interviewed while applying for identity cards at Mexican consulates in the United States ... an overwhelming majority would vote in Mexican elections scheduled for next year if they had the opportunity."Includes a summary and the complete report.

Halfway between South America and New Zealand, in the remote South Pacific, is Rapa. This horseshoe-shaped, 13.5 square-mile island of volcanic origin, located essentially in the middle of nowhere, is "a microcosm of the world's situation,"says a University of Oregon archaeologist. Smithsonian Folklife Festival
Information about this annual Smithsonian Institution festival "asserting the ability of people to converse with and understand each other."The festival typically includes "programs of music, song, dance, celebratory performance, crafts and cooking demonstrations, storytelling, illustrations of workers' culture, and narrative sessions for discussing cultural issues."Features descriptions of programs at the current year's festival, and archives of festivals back to 1997. From the Smithsonian Center for Folklife and Cultural Heritage. Important Factors Involved In The Synthesis Of Starch In Plants
The classic model for explaining the biosynthesis of starch in plant leaves has been seriously called in to question. While to date the accepted belief has been that starch biosynthesis is produced solely in the chloroplast, biologist Nora Alonso Casajús' PhD provides evidence to show that the greatest part of the precursor molecule in starch biosynthesis -- known as ADPG -- accumulates in the cytosol of the plants.
