Submission + - Withdrawal Effects "No Net Benefit Caffeine

Jeroen Vlek writes: As I am sure that /. contains many caffeine fiends, like myself, the following research is of interest.

"The team demonstrated that stopping daily caffeine consumption produces changes in cerebral blood flow velocity and quantitative EEG that are likely related to the classic caffeine withdrawal symptoms of headache, drowsiness and decreased alertness."

What is even more surprising is that they found no net benefit of using caffeine:

"In contrast to what most of us coffee lovers would think, our study showed no difference between when the participant was maintained on chronic placebo and when the participant was stabilized on chronic caffeine administration. What this means is that consuming caffeine regularly does not appear to produce any net beneficial effects, based on the measures we examined."

I will just stick to tea and cola then. Oh, wait.

Race Car Made With Veggies And Powered By Chocolate 83

IS4110 writes "A new racing car made with potatoes and carrots and powered with chocolate waste has been developed by the Innovative Manufacturing Research Centre of the University of Warwicks in the UK. The university's vehicle, called WorldFirst F3 project, has a steering wheel made of curran, a material derived from carrots, that is expected to replace glass fiber and carbon fiber. It also has a racing seat made of SoyFoam, a soybean oil-based, flexible foam material. Wing mirrors incorporate materials derived from potato starch, a bib made from flax fiber, and lubricants based on plant oils."

Dead Space Highlights Disparity Between Plot and Gameplay 87

Gamasutra is running an opinion piece praising recent horror-action game Dead Space for its pacing and gameplay while simultaneously criticizing the plot and the attempts to scare the player. Quoting: "What Dead Space is, is carefully and stylishly unoriginal. You'll love playing it, but when you aren't playing it, it's hard to say what's so great about it. It has some really great set pieces, some sweet effects, solid gameplay, an amazing interface and that's all. Anything and everything having to do with dialogue and story comes off as rote. ... You get the feeling the developer are trying very hard, though. When I see a dark shape in the distance, which turns and disappears, I don't get scared. I know he'll pop out of a vent later! Likewise, when I find a scientist who promptly slits her throat because of the horror, I just check for an item drop. None of the survivors ever surprise you and go hostile (which I think would have been a brilliant scare), so you never have to worry."

Reducing the Risk of Human Extinction 399

wiredog sends in a study from the University of Pittsburgh Medical Center Center For Biosecurity, assessing risks of human extinction and the costs of preventing it. "In this century a number of events could extinguish humanity. The probability of these events may be very low, but the expected value of preventing them could be high, as it represents the value of all future human lives."

Colliding Galaxies Reveal Colossal Black Holes 134

Matt_dk writes "New observations made with the Submillimeter Array of telescopes in Hawaii suggest that black holes — thought to exist in many, if not all, galaxies — were common even in the early Universe, when galaxies were just beginning to form. Astronomers have found two very different galaxies in the distant Universe, both with colossal black holes at their hearts, involved in a spectacular collision."
