Even during good times, small businesses have a hard time finding loans. In this recession, it’s been almost impossible. 
Why It Is Easy To Encode New Memories But Hard To Hold Onto Them
sea-maid submitted, created time 7 months 3 weeks (www.sciencedaily.com)
Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories. In the July 13, 2009 issue of the Journal of Cell Biology, Rex et al. reveal that LTP's actin reorganization occurs in two stages that are controlled by different pathways, a discovery that helps explain why it is easy to encode new memories but hard to hold onto them.
Indian fossil find resolves fraud accusations

A decade-old dispute over the authenticity of Indian fossils that are some of the earliest examples of multicellular life seems to have been resolved. As a result, an Indian researcher has been cleared of simmering suspicions of specimen tampering.
Gene Sequencing Technology Taken Up by Conservationists

So perhaps gene sequencing hasn't advanced to the stage where people are actually talking about cloning individuals from the U.N.'s red list--the list of highly endangered animals--but there are a few tricks available to conservationists that weren't available even a few years ago.
Thanks to new techniques, the cost of sequencing large amounts of information has gone way down. This is giving zoologists a wonderful chance to study the extinction process by taking samples not only from living organisms but also from museum specimens
Ten genes identified in connection with sudden cardiac death

You're sitting at your desk and suddenly your heart is beating in overdrive or worse, lurching along like a car on fumes. It is a shocking, uncomfortable and frightening sensation.
Irregular heart rhythms are a common cause of sudden cardiac death or SCD, a condition that accounts for 450,000 deaths annually in the United States. Scientists are now closer to understanding what causes SCD and who it may strike, said Gonçalo Abecasis, associate professor of biostatistics at the University of Michigan School of Public Health
New Method Could Improve Vaccines for Both Seasonal and Bird Flu
piggy submitted, created time 11 months 3 weeks (www.sciencedaily.com)
A new computerized testing method could help world health officials better identify those flu vaccines that are most effective against multiple strains of influenza. Rice University scientists who created the method say tests using data from bird flu and seasonal flu outbreaks suggest their method can better gauge the efficacy of proposed vaccines than tests used today can.
Rice's Michael Deem, the lead scientist on the project, will present the group's results March 19 at the American Physical Society's 2009 meeting in Pittsburgh
Health Is Going High Tech wIth Camera Pills, Health Sensors and Ultrasound Maps for Surgeons

In a project involving the collaboration of several institutes, research scientists of the Johannes Gutenberg University Mainz have succeeded in gaining further insight in the functioning of endogenous mechanisms that protect against the development of Alzheimer's disease. It was found that the activity of the enzyme α-secretase is mainly responsible for these protective effects.
Survival of the Weakest? Cyclical Competition of Three Species Favors Weakest As Victor
sea-maid submitted, created time 1 year 2 weeks (www.sciencedaily.com)
Standard Darwinian evolutionary theory teaches "survival of the fittest": any two species that require the same niche will compete until one or the other is gone, either dead, migrated or adapted to different circumstances. Natural selection will favor one or the other, but there are no cases in which both species remain. And species get stronger over time. Faster predators provide an evolutionary pressure for faster prey, which in turn provides pressure for faster predators. Things get fitter, not less fit
Calculating gene and protein connections in a Parkinson's disease model

A novel approach to analyzing cellular data is yielding new understanding of Parkinson's disease's destructive pathways.
Whitehead Institute and Massachusetts Institute of Technology (MIT) scientists have employed this new computational technique to analyze alpha-synuclein, a mysterious protein that is associated with Parkinson's disease.
Cells are constantly adapting to various stimuli, including changes in their environment and mutations, through an intricate web of molecular interactions. Knowledge of these changes is crucial for developing new treatments for diseases
Statistical Analysis Could Yield New Drug Target for Multiple Sclerosis

An elaborate statistical analysis of genes from more than 7,000 individuals has identified an amino acid that appears to be a major risk factor for multiple sclerosis, a devastating autoimmune disorder that afflicts 2.5 million people worldwide.
Astronomers Unveiling Life's Cosmic Origins

Processes that laid the foundation for life on Earth -- star and planet formation and the production of complex organic molecules in interstellar space -- are yielding their secrets to astronomers armed with powerful new research tools, and even better tools soon will be available.
The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes
piggy submitted, created time 1 year 2 months (www.eurekalert.org)
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential.
In the January 2, 2009 issue of Science, Yan and Liu, researchers at ASU's Biodesign Institute and faculty in the Department of Chemistry and Biochemistry, reveal for the first time the three-dimensional character of DNA nanotubules, rings and spirals, each a few hundred thousandths the diameter of a human hair

New system citation system allows cross-disciplinary review. Is this the next h-index?
Darkfrog submitted, created time 1 year 4 months (www.nature.com)
Ordinarily, scientists use their h-index to determine whether their articles are up to snuff, citation-wise, and the system works well enough. Everyone accepts that it cannot be used across disciplines because overall citation rates are different. An aerospace paper that has twenty citations has made a huge impact. A developmental biology paper that has a hundred citations is skimming average.
