Morphine dependency blocked by single genetic change
Morphine’s serious side effect as a pain killer – its potential to create dependency – has been almost completely eliminated in research with mice by genetically modifying a single trait on the surface of neurons. The study scientists think a drug can be developed to similarly block dependency.

Cats' family tree rooted in Fertile Crescent, study confirms
The Fertile Crescent of the Middle East has long been identified as a “cradle of civilization” for humans. In a new genetic study, researchers at the University of California, Davis, have concluded that all ancestral roads for the modern day domestic cat also lead back to the same locale.

Synthetic Biology: It's Not What You Learned, But What You Made
With the news yesterday that J. Craig Venter Institute scientists had built the first bacterial genome from the raw chemical components of DNA, we saw a host of science writers step up to contextualize the work and explain its significance.

FBI's New Technology Revolutionizes DNA Analysis
At the FBI Crime Lab in Quantico, Va., experts are finding new and better uses for what many people see as a forensic sure thing -- DNA. Cases unsolvable just a decade ago, are now ripe for reopening.

Unexpected protein interaction suggests new ALS drug target
Discovery of an unexpected protein-protein interaction has led University of Iowa scientists and colleagues to identify a drug that slows the progression of Amyotrophic Lateral Sclerosis (ALS) in mice and nearly doubles the animals' lifespan. The study is published Jan. 24 online in the Journal of Clinical Investigation.

Australian girl changes blood group, immune system
An Australian teenage girl has become the world's first known transplant patient to change blood groups and take on the immune system of her organ donor, doctors said on Friday, calling her a "one-in-six-billion miracle."

Search for the 'on' switches may reveal genetic role in development and disease
A new resource that identifies regions of the human genome that regulate gene expression may help scientists learn about and develop treatments for a number of human diseases, according to researchers at Duke’s Institute for Genome Sciences & Policy (IGSP).

Genome stitched together by hand
Scientists have succeeded in stitching together an entire bacterial genome, creating in the lab the full set of instructions needed to make a living thing. The stage is now set for the creation of the first artificial organism — and it could be achieved within the year.

Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
The shells of diatoms are so heavy that when they die in the oceans they typically sink to watery graves on the seafloor, taking carbon out of the surface waters and locking it into sediments below.

Human Gene Count Tumbles Again
y the time the working draft of the human genome was published in 2001, the best approximation stood at 35,000, yet even that number has fallen. A new analysis, one that harnesses the power of comparing genome sequences of various organisms, now reveals that the true number of human genes is about 20,500, thousands fewer than what is currently listed in human gene catalogs.

Gene Therapy Cancers Prompt Design of Safer Virus
The announcement last month that a fifth child who received gene therapy for an immune system disease has developed leukemia was the latest blow to the field of gene therapy. But there's new hope: The U.K. team running the trial reports this week that a safer formulation of the treatment can cure the disease in mice and should also work in people.
