Connie Bruck in The New Yorker: On July 23rd, officials of the American Israel Public Affairs Committee—the powerful lobbying group known as AIPAC—gathered in a conference room at the Capitol for a closed meeting with a dozen Democratic senators. The...
Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression and it's all in our genomic data.
Three related studies in Nature, tell a similar story: even though humans, worms, and flies bear little obvious similarity to each other, evolution used remarkably similar molecular toolkits to shape them.
There are dramatic differences between species in genomic regions populated by pseudogenes, molecular fossils of working
Learning a new skill is easier when it is related to an ability we already have. For example, a trained pianist can learn a new melody easier than learning how to hit a tennis serve.
Scientists from the Center for the Neural Basis of Cognition (CNBC) have discovered a fundamental constraint in the brain that may explain why this happens. Writing in Nature, they say that there are limitations on how adaptable the brain is during learning and that these restrictions are a key determinant for
