Tuiten published some results from small, preliminary trials in the March issue of The Journal of Sexual Medicine. His full data, which he has just finished tabulating and will soon be taking to the F.D.A., show Lybrido bestowing unmistakable benefits in desire — and in rates of orgasm. (The outcomes for Lybridos aren’t thoroughly compiled, but he says that early results look about as positive.) Tuiten is confident that the F.D.A. will send him to do another larger set of trials, which will involve about 1,200 subjects. Plenty of drugs fail at that stage of replication. Unexcited? There May Be a Pill for That

The case for outlawing the practice of talking on cell phones while driving got a boost from the latest breakthrough from the innovation labs of Freie Universität Berlin. German scientists working there have installed a car with new technology that can read the driver's brain waves, thus allowing the car to be steered entirely by thought, reports Science Daily. Needless to say, you probably don't want to be distracted while driving this vehicle.
What Is the Memory Capacity of the Human Brain? Can an old head injury suddenly cause detrimental effects much later in life?—Anonymous, via e-mail Douglas Smith, professor of neurosurgery and director of the Center for Brain Injury and Repair at the University of Pennsylvania, answers: ALTHOUGH A BRAIN INJURY from a car accident or a collision during a football game often seems to cause a sudden change to cognitive ability years later, this change does not just appear out of the blue—the damage has been building up slowly, unnoticed, over time. Postinjury, the progressive brain deterioration that may occur likely reaches a tipping point, after which the loss of function “suddenly” becomes obvious.
Nootropics (/noʊ.əˈtrɒpɨks/ noh-ə-TROP-iks), also referred to as smart drugs, memory enhancers, neuro enhancers, cognitive enhancers, and intelligence enhancers, are drugs, supplements, nutraceuticals, and functional foods that purportedly improve mental functions such as cognition, memory, intelligence, motivation, attention, and concentration. The word nootropic was coined in 1972 by the Romanian Dr. Corneliu E. Giurgea, derived from the Greek words νους nous, or "mind," and τρέπειν trepein meaning "to bend/turn". Nootropics are thought to work by altering the availability of the brain's supply of neurochemicals (neurotransmitters, enzymes, and hormones), by improving the brain's oxygen supply, or by stimulating nerve growth.
Piracetam (sold under many brand names) is a nootropic in the racetams group, with chemical name 2-oxo-1-pyrrolidine acetamide. It shares the same 2-oxo-pyrrolidone base structure with 2-oxo-pyrrolidine carboxylic acid (pyroglutamate). Piracetam is a cyclic derivative of GABA.
