This week, ScienceNOW reported that weight gain may result from a loss of genes; why firstborns don't share; monkeys may use grammar; and a quasar that built a galaxy, among other stories.
Gene therapy researchers are approaching a key milestone: They appear to have controlled an inherited blood disorder called β-thalassemia that's more common than any disease treated so far with gene therapy.
A massive effort to catalog genetic variation among Asians described on page 1541 of this week's issue of Science has concluded that Asia was initially settled by a single wave of migration along the coast.
Construction began in Bangalore last month on the Institute for Stem Cell Biology and Regenerative Medicine, a $50 million center to be built alongside an existing biology powerhouse and a planned $12 million technology center that will seek to commercialize the biocluster's findings.
deCODE genetics Inc. filed for bankruptcy last week, but the company will continue operations with a loan from a potential buyer. And its flamboyant leader, Kari Stefánsson, says he hopes to stay on as leader of deCODE's hunt for disease-causing genes.
Gene expression variation in maize hybrids is influenced by distant DNA sequences subject to paternal genomic imprinting.
Researchers have proposed that genes that code for proteins that are part of complexes are most likely to survive the purging that follows whole-genome duplications. Increasing evidence from the 9th International Plant Molecular Biology Congress and other meetings suggests that this so-called gene balance hypothesis may be correct.
ScienceNOW this week reported that meditation halves the risk of heart disease, empathy is in our genes, holes can block light, and new neurons make room for new memories, among other stories.
