MORE CYCLISTS MEAN FEWER ACCIDENTS

Ecomodder - It may seem counterintuitive, but according to a recent report more cyclists on the road mean fewer accidents involving cyclists and motor vehicles. . . "It's a virtuous cycle," says Dr Julie Hatfield, an injury expert from University of New South Wales. "The likelihood that an individual cyclist will be struck by a motorist falls with increasing rate of bicycling in a community. And the safer cycling is perceived to be, the more people are prepared to cycle." Also, even more encouragingly, it doesn't seem that cycling infrastructure is responsible for the change:

Experts say the effect is independent of improvements in cycling-friendly laws such as lower speed limits and better infrastructure, such as bike paths. Research has revealed the safety-in-numbers impact for cyclists in Australia, Denmark, the Netherlands, 14 European countries and 68 Californian cities.

FEDERAL COURT: CELL PHONES COVERED BY FOURTH AMENDMENT

Electronic Frontier Foundation - In an unprecedented victory for cell phone privacy, a federal court has affirmed that cell phone location information stored by a mobile phone provider is protected by the Fourth Amendment and that the government must obtain a warrant based on probable cause before seizing such records.

The Department of Justice had asked the federal court in the Western District of Pennsylvania to overturn a magistrate judge's decision requiring the government to obtain a warrant for stored location data, arguing that the government could obtain such information without probable cause. The Electronic Frontier Foundation, at the invitation of the court, filed a friend-of-the-court brief opposing the government's appeal and arguing that the magistrate was correct to require a warrant. The court agreed with EFF and issued an order affirming the magistrate's decision.

EFF has successfully argued before other courts that the government needs a warrant before it can track a cell phone's location in real-time. However, this is the first known case where a court has found that the government must also obtain a warrant when obtaining stored records about a cell phone's location from the mobile phone provider.

VEGETARIANS FACE BRAIN SHRINKAGE

Times of India - Scientists have discovered that going veggie could be bad for your brain-with those on a meat-free diet six times more likely to suffer brain shrinkage.

Vegans and vegetarians are the most likely to be deficient because the best sources of the vitamin are meat, particularly liver, milk and fish. Vitamin B12 deficiency can also cause anaemia and inflammation of the nervous system. Yeast extracts are one of the few vegetarian foods which provide good levels of the vitamin.

The link was discovered by Oxford University scientists who used memory tests, physical checks and brain scans to examine 107 people between the ages of 61 and 87.

When the volunteers were retested five years later the medics found those with the lowest levels of vitamin B12 were also the most likely to have brain shrinkage. It confirms earlier research showing a link between brain atrophy and low levels of B12.

Brain scans of more than 1,800 people found that people who downed 14 drinks or more a week had 1.6% more brain shrinkage than teetotallers. Women in their seventies were the most at risk.

Beer does less damage than wine according to a study in Alcohol and Alcoholism.

And being overweight or obese is linked to brain loss, Swedish researchers discovered. Scans of around 300 women found that those with brain shrink had an average body mass index of 27 And for every one point increase in their BMI the loss rose by 13 to 16%.

GREAT MOMENTS IN CANADIAN POLITICS

Slate - On Sunday morning, Prime Minister Harper began the race by predicting "a very nasty kind of personal-attack campaign." Two days later, his party briefly released an ad that showed a bird defecating on the leader of the Liberal Party. So much for Canadians being nice.
