Cervical cancer screening failure linked to poverty

African-American women living in communities with high poverty rates are less likely to be screened for cervical cancer, even after adjusting for other factors known to raise the risk of non-screening, such as older age, lower educational attainment, and smoking. The study, appearing in the February 1, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, demonstrates that a community's income status predicts cervical screening rates. more  

Sickle cell disease corrected in human models using stem cell-based gene therapy

In a study to be published in the January 2006 issue of Nature Biotechnology, researchers led by a team of scientists at Memorial Sloan-Kettering Cancer Center have devised a novel strategy that uses stem cell-based gene therapy and RNA interference to genetically reverse sickle cell disease (SCD) in human cells. This research is the first to demonstrate a way to genetically correct this debilitating blood disease using RNA interference technology. more

Studying the fate of drugs in wastewater

Researchers at the National Institute of Standards and Technology (NIST) have published an interesting study that sheds light on the fate of a familiar pharmaceutical as it enters the waste stream. In work initially described last year, NIST chemists investigated probable chemical reactions involving acetaminophen when the drug is subjected to typical wastewater processing. more  

DNA self-assembly used to mass-produce patterned nanostructures

Duke University scientists have used the self-assembling properties of DNA to mass-produce nanometer-scale structures in the shape of a 4x4 grids, on which patterns of molecules can be specified. They said the achievement represents a step toward mass-producing electronic or optical circuits at a scale 10 times smaller than the smallest circuits now being manufactured. more

Craniofacial researchers have developed an animal model that explains how skull malformations occur and how they might be prevented. more

Harry Potter protects children from injury 

Harry Potter books seem to protect children from traumatic injuries, according to a study in this week's BMJ. more

Money won't buy you happiness

Money is not the key to happiness, argues an editorial in this week's BMJ - but family networks and having a full life outside work may do the trick. "Individuals usually get richer during their lifetimes but not happier" says the author. more

 

Okay, we get it. Money doesn't buy happiness.
