An employee of Japanese pillow maker Lofty, displays a prototype model of the "Sleep Doctor" pillow in Tokyo. The Sleep Doctor analyses slumber patterns and subsequently provides 40 kinds of advice and encouragement on a miniature screen, with sensors measuring head and body movements to calculate how much "pleasant sleep" you´ve had on a scale of 30 to 95 percent. The device will go on the market for 390 USD.

"La Gioconda", a painting which bears a striking resemblance to Leonardo da Vinci´s famous "Mona Lisa" is seen today at the Portland Museum of Art in Portland, Maine. Conservators at Harvard University were unable to confirm or disprove whether da Vinci painted it as a preparatory study for the "Mona Lisa" or if it was done by a follower of da Vinci.
