2010 Science News of the Year: Body & Brain
Credit: © Bettmann/Corbis Gene therapy moves forward Despite their promise, technologies to correct defective genes have been plagued by safety problems leading to unintended — and sometimes fatal — outcomes. But scientists are inching toward safer, more effective gene therapies that may one day treat a range of diseases, from psychiatric disorders to autoimmune diseases […]

2010 Science News of the Year: Genes & Cells
Credit: © Joe McNally/reconstruction by Kennis and Kennis Gene sequencing for all, even Neandertals An unprecedented picture of life’s diversity is emerging as researchers publish the full genetic instruction books of a growing list of species — including one that has been extinct for more than 30,000 years. A project sequencing Neandertal DNA harvested from […]

Mind the gap: Genetic knowledge and medical power
Since the completion of the Human Genome Project a decade ago, much excitement has swirled around the possibility that determining a person’s genetic makeup could help doctors personalize the diagnosis, treatment and prevention of disease. But James P. Evans, a physician and geneticist at the University of North Carolina at Chapel Hill, says the promises […]

Greed may breed financial fitness, but evolution allows unselfishness to survive
If greed is good, as Gordon Gekko proclaimed in the 1987 movie Wall Street, then economics ought to be a superlative science. After all, at the core of economic theory sits a greedy idealization of human nature known as Homo economicus. It’s a fictitious species that represents the individual economic agent, motivated by selfishness. H. […]
