Scientists have figured out how to grow human stem cells into "cerebral organoids" - blobs of tissue that mimic the anatomy of the developing brain. The advance, reported online Wednesday by the journal Nature, won't allow scientists to grow disembodied brains in laboratory vats, said study leader Juergen Knoblich, a stem cell researcher at the Institute of Molecular Biotechnology of the Austrian Academy of Science in Vienna. But it does offer researchers an unprecedented view of human brain anatomy, he said.

How an autistic baby's brain fires up in response to words at 2 years of age may predict how well that child will learn language and even think and behave later in life, a new study shows. The research, published this week in the online journal PLOS One, suggests that a “social gateway” based in the brain impedes not only early language processing, but a broader spectrum of cognitive development, including the ability to adapt behavior to circumstances, according to Patricia Kuhl, who studies early language and brain development at the University of Washington's Institute for Brain and Learning Sciences.

Nothing gets our attention like pain. But pain is more than the body's miniature cattle prod to get us to heed a wound, rest a swollen ankle, or stop eating chili peppers. Pain may be the language between animals and microbes. Far from being a product of an inflamed immune system, aggravated nerves far from the spine and brain appear to communicate with invading bacteria and regulate the fight against them, according to a study published online Wednesday in the journal Nature.

The brains of children with attention deficit hyperactivity disorder develop more slowly than those of other children but eventually catch up, according to a government study published Monday that suggests ADHD may be a transient condition, at least for some. Using advanced imaging techniques, scientists found that the cortices of children with ADHD reach peak thickness an average of three years later than children without the disorder.

Scientists recently reported they had pieced together a high-quality sequence of an archaic human relative, the Denisovans. Among other things, the researchers took a close look at the ways in which we differ from these people, who were named after the place where their traces were discovered: Denisova Cave in the Altai Mountains of Siberia. Here's a little more about the things the scientists found that didn't make it into the article about the Denisovan genome we published Thursday . It's "fascinating" to see the DNA changes that spread to most or all modern humans since our line split off from that of the Denisovans and the Neanderthals, said senior author Svante Paabo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

In a finding that points to a link between environmental toxins and autism, a new study shows that children who were exposed to the highest levels of traffic-related air pollution during gestation and in early infancy were three times more likely to be diagnosed with the neurodevelopmental disorder than were those whose early exposure to such pollutants was very low. The study , published Monday in the Archives of General Psychiatry, found that...

ARITHMETIC flashcards at the age of 3 won't unleash the next Einstein. Nor will choosing a precise combination of educational toys guarantee a future good job and happy life. It's attention and play with adoring adults that stimulates brain development -- not just in individual infants, but in the nation's future workforce.

"Teenagers are often impulsive. " That's the opening sentence of a new scientific paper. Raise your hand if you're a parent of an adolescent and agree. Impulsivity is a major focus on researchers studing the brain and human behavior because being overly impulsive or a risk-taker or dare-devil is linked to more problems in life. Kids who can't seem to control their impulses make bad decisions: like swallowing a mysterious pill someone brought to school or riding on a skateboard attached to a car. They are driven by a need for instant gratification and fail to consider the long-term consequences of their actions.

Taking a common class of antidepressants called serotonin reuptake inhibitors, or SRIs, during pregnancy alters the developmental time-course of the child's language processing, according to a new study published Monday in the Proceedings of the National Academy of Sciences. While the results are striking, they hardly suggest the practice should be stopped: The researchers found that the children of women who are depressed while pregnant and who do not take medication are also born with an altered course of development.

As the dramatic abortion debate plays out in courtrooms and legislatures across the nation, a basic and vitally important question arises ever more insistently--when does human life begin? The Roman Catholic Church claims conception is life's starting point, whereas most current abortion laws are keyed to when the fetus might survive if born prematurely (at the end of the second trimester).
