Generations are generally useless, aside from marketing plans. The Baby Boom happened in 1946, after soldiers returned home from war (the occupying soldiers came from a different, supplemental draft so they often already had kids) and it was later that marketing groups changed them into a generation stretching to 1964 and even 1965.

In 2007, members of the Haystack Group in MIT's Computer Science and Artificial Intelligence Laboratory released a set of Web development tools called Exhibit, which lets novices quickly put together interactive data visualizations, such as maps with sortable data embedded in them, sortable tables that automatically pull in updated data from other sites, and sortable displays of linked thumbnail images.

Medicine stopped being symptom-based over 50 years ago but psychology still uses it. Little is known about why or how the brain works the way it does, much less personality variation, so if a psychological therapy works, it works.

Heart attack death has declined across all regions of the United States but it remains proportionately higher in the South, according to a paperat the American College of Cardiology's 63rd Annual Scientific Session.

In previous research (Nature, July 2013), UC Berkeley scientists Beatriz Vicoso, Ph.D., and Doris Bachtrog, Ph.D., determined that genes on the so-called "dot chromosome," or fourth chromosome, of the fruit fly Drosophilia melanogaster are X-linked in three other related fly species.

These and other findings revealed that the fruit fly's "dot chromosome" had descended from a differentiated X chromosome and suggests that several of the chromosome's puzzling features are remnants of its heritage as a sex chromosome. For example, the expression levels of genes on the "dot chromosome" generally are higher in female than in male fly embryos during early development.

Four years ago, University of Iowa scientists discovered that mutations in the prickle gene in Drosophila were responsible for much more than merely altering the bristles on the fly's body to point them in the wrong direction.

Prompted by a colleague's finding that PRICKLE gene mutations were responsible for triggering a form of epilepsy in humans, John Manak, Ph.D., who led the fly research team, took a closer look at the Drosophila prickle mutants. (PRICKLE refers to the human gene, while prickle is the Drosophila form of the gene.)
