1. Young children's moral understanding more sophisticated than previously thought
   When her Daily Mail column about Stephen Gately's death provoked an avalanche of complaints, the disgraced Jan Moir issued a press statement in which she said "it was never [her] intention" to upset people. Defensively speaking, Moir's choice of words was astute. In judging moral responsibility, we adults focus almost exclusively on intention rather than outcome. Stated starkly, the person who de
2. Reducing Alzheimer's-related protein in young brains improves learning in Down syndrome animal model
   Reducing a protein called beta-amyloid in young mice with a condition resembling Down syndrome improves their ability to learn, researchers have found.
3. Our brains are more like birds' than we thought
   For more than a century, neuroscientists believed that the brains of humans and other mammals differed from the brains of other animals, such as birds (and so were presumably better). Researchers have now found that a comparable region in the brains of chickens concerned with analyzing auditory inputs is constructed similarly to that of mammals.
4. Why New Year's Resolutions Tend to Fail and How We Can Achieve Them
   Year after year, so many people make New Year's resolutions that over time wither and fade into another failed attempt to transform some aspect of their lives. What begins with a hopeful optimism unravels in yet another unmet aspiration. It's always a curiosity to me how we come to try to evoke change in the same way that gives us the same failure. I imagine that if we conducted a survey six mont
5. More Evidence That Intelligence Is Largely Inherited: Researchers Find That Genes Determine Brain's Processing Speed
   A new type of brain imaging scanner shows that intelligence is strongly influenced by the quality of the brain's axons or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information. And since the integrity of the brain's wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought.
