Results from multiple studies indicate that valerian - a tall, flowering grassland plant - may reduce the amount of time it takes to fall asleep and help you sleep better. Of the many valerian species, only the carefully processed roots of the Valeriana officinalis have been widely studied. However, not all studies have shown valerian to be effective, and there may be some dangers.

It's natural for men to notice a gradual decrease in sex drive (libido) as they age. The degree of this decline varies, but most men maintain at least some amount of sexual interest well into their 60s and 70s.

Ten years ago Neil Gershenfeld, professor of media arts and sciences and the founder and director of MIT’s Center for Bits and Atoms (CBA), began an outreach project that has grown into a global program for empowering local invention, engineering education, and entrepreneurship. He developed self-contained fabrication shops equipped with the latest rapid-prototyping equipment - laser cutters, computer-controlled milling machines, 3-D printers, and so on - that could be easily installed anywhere in the world. Since then, hundreds of what came to be called Fab Labs have been installed in dozens of countries, and last August thousands of the labs’ users and operators gathered at MIT for a 10th-anniversary conference.
