The successful operation of the Large Hadron Collider marked the resumption of the world’s biggest and most expensive physics experiment.

Voracious Invader May Be Nearing Lake Michigan
11/22/2009 11:44:43 AM
Evidence of Asian carp, a fish that some fear could destroy the ecosystem of Lake Michigan, has been found beyond a barrier intended to keep the fish out.

U. of Nebraska Defeats Tighter Limits on Stem Cell Research

The effort had been seen by opponents as a possible new front in the national debate over the matter.

Albert Crewe, First to Show a Single Atom, Is Dead at 82
11/22/2009 11:44:43 AM
Dr. Crewe, a University of Chicago physicist, developed the high-resolution electron microscope that captured the first image of an individual atom.

Termites create sustainable monoculture fungus farming
11/22/2009 11:44:44 AM
Food production of modern human societies is mostly based on large-scale monoculture crops, but it now appears that advanced insect societies have the same practice. Our societies took just ten thousand years of (mainly cultural) evolution to adopt this habit and we are far from convinced that it is sustainable. Farming ants and termites had tens of millions of years to evolve their fungus farming systems and here monocultures are apparently evolutionary stable.

Researchers find new piece of bovine spongiform encephalopathy (BSE) puzzle
11/22/2009 11:44:44 AM
A new treatment route for bovine spongiform encephalopathy (BSE) and its human form Creutzfeldt Jakob disease could be a step closer based on new results from scientists in the UK. The team has found that a protein called Glypican-1 plays a key role in the development of BSE.

Sweet as can be: How E. coli gets ahead
11/22/2009 11:44:44 AM
Scientists have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut.

DNA molecules in moss open door to new biotechnology
11/22/2009 11:44:44 AM
Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, opening the door to applications of a number of powerful techniques in plant research.

Tooth-binding micelles containing antimicrobials may provide long-term cavity protection
11/22/2009 11:44:44 AM
A new study suggests that tooth-binding micelles (or particles) may provide long-term cavity protection by adhering to tooth surfaces and gradually releasing encapsulated antimicrobials. Formulation of a mouthwash-based delivery system is anticipated, ultimately simplifying application and increasing at-home patient compliance.
