As some of you know, I'm an advisor and/or investor in a number of start-up Internet companies. One in particular is quite remarkable, Club Botanic, based in San Francisco, is a unique flower delivery firm that offers monthly subscriptions to its services as well as single orders. For a reasonable price you can order beautiful flower arrangements and have them delivered to your home or office.

Scientists have found a compelling clue in the quest to learn what causes age-related memory problems, and to one day be able to tell if those misplaced car keys are just a senior moment or an early warning of something worse.

Playing 40 hours or Starcraft, the real-time strategy game pitting humans and two alien species against each other, can make people think more flexibly.
So concludes a study this month that compared groups of people who played The Sims, StarCraft with easier conditions, and StarCraft with harder conditions that required players to keep track of a more complicated scenario.

Memory loss leading to Alzheimer's disease is one of the greatest fears among older Americans.While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer's, for which there currently is no cure.The study, led by Dr. J.

Cognitive performance of adolescent girls who walk to school is better than that of girls who travel by bus or car. Moreover, cognitive performance is also better in girls who take more than 15 minutes than in those who live closer and have a shorter walk to school.
These are some of the conclusions of a study published in Archives of Pediatrics & Adolescent Medicine.
