Dthief writes "Bristol University researchers found that coffee drinkers develop a tolerance to both the anxiety-producing and the stimulating effects of caffeine, meaning that it only brings them back to baseline levels of alertness, not above them. 'Although frequent consumers feel alerted by caffeine, especially by their morning tea, coffee, or other caffeine-containing drink, evidence suggests that this is actually merely the reversal of the fatiguing effects of acute caffeine withdrawal,' wrote the scientists, led by Peter Rogers of Bristol's department of experimental psychology."

krou writes "Monkseaton High School in North Tyneside, UK, began an experiment in October that saw its 800 pupils ranging in age from 13-19 attend school an hour later than normal, at 10am. Early results indicate that 'general absence has dropped by 8% and persistent absenteeism by 27%.' Head teacher Paul Kelley supported the idea because he believed that 'it was now medically established that it was better for teenagers to start their school day later in terms of their mental and physical health and how they learn better in the afternoon', and he now claims that the children are becoming 'happier better educated teenagers' as a result of the experiment. The experiment is being overseen by Oxford neuroscience professor Russell Foster. 'He performed memory tests on pupils at the school which suggested the more difficult lessons should take place in the afternoon. He said young people's body clocks may shift as they reach their teenage years — meaning they want to get up later not because they are lazy but because they are biologically programmed to do.'"

An anonymous reader notes a Reuters report of a study, published in the Journal of Experimental Psychology: Applied, confirming that Mobile phone calls distract drivers far more than even the chattiest passenger, causing drivers to follow too closely and miss exits. California's ban on using a handheld cell phone while driving, which went into effect last summer, is looking less than fully effective. A handful of other states have instituted similar bans, but none has forbidden driving while talking on a cell phone at all. "Using a hands-free device does not make things better and the researchers believe they know why — passengers act as a second set of eyes, shutting up or sometimes even helping when they see the driver needs to make a maneuver."

NinjaCoder writes "The Guardian has an interesting article based on a new book (Outliers: The Story Of Success, by Malcolm Gladwell) which examines some persons of interest to computer technology (Bill Joy, Bill Gates and Steve Jobs, amongst others). It examines reasons for their successes and strongly suggests a link between practice (10,000 hours by age 20 being the magic milestone) and luck. This maybe an obvious truism, but the article does give interesting anecdotes on how their personal circumstances led to today's technological landscape. It points out that many of the luminaries of the current tech industry were born around 1955, and thus able to take advantage of the emerging technologies.
