Toyota Recall Might Be Caused by Cosmic Rays

From Live Science:

It may not lessen Toyota's woes to hear that the problems the company has been having with faulty gas pedals could be blamed on cosmic rays from space. Sound unbelievable? The concept is actually a lot more plausible than you might think.

Toyota's sticky gas pedals caused sudden and unintended acceleration in several of the automaker's top-selling Toyota and Lexus-brand cars, which led to a massive recall of more than 9 million vehicles worldwide, beginning in November.

"We only used dead trees," emphasized tree ring researcher Thomas Swetnam of the University of Arizona. Swetnam led the study that was reported in a recent issue of the journal Fire Ecology. "We spent multiple years collecting the wood and hauling it back to Tucson."

This year, all Webster has to do is persuade consumers that Office is cool, that Mom and Dad need their own Xbox, and that a Windows Phone can be a credible alternative to the iPhone. Luckily, Microsoft is willing to spend a few bucks to do all that.

Biblical Plagues Really Happened Say Scientists

From The Telegraph:

The Biblical plagues that devastated Ancient Egypt in the Old Testament were the result of global warming and a volcanic eruption, scientists have claimed.

Researchers believe they have found evidence of real natural disasters on which the ten plagues of Egypt, which led to Moses freeing the Israelites from slavery in the Book of Exodus in the Bible, were based.

But rather than explaining them as the wrathful act of a vengeful God, the scientists claim the plagues can be attributed to a chain of natural phenomena triggered by changes in the climate and environmental disasters that happened hundreds of miles away.

From New Scientist:

After almost a year of negotiation, the US and Russia have finally settled on a plan to further reduce their vast nuclear arsenals. If the new agreement is approved, the number of deployed warheads by will be cut by 30 per cent over previous targets. But an ongoing dispute over a European missile defence shield has the potential to scupper the plans.

The US and Russia hold some 95 per cent of the world's nuclear arms, including an estimated 4700 deployed nuclear warheads. The new agreement – a follow-up to the 1991 Strategic Arms Reduction Treaty (START) – would cut the number to 1550 warheads per country over the course of seven years.
