Nowadays, we can rely on GPS receivers or magnetic compasses to tell us how to reach our destination. Some 1000 years ago, Vikings had none of these advanced navigation tools. Yet, they successfully sailed from Scandinavia to America in near-polar regions where it can be hard to use the Sun and the stars as a compass. Clouds or fog and the long twilights characteristic of polar summers complicate direct observations of these celestial bodies. So how did they find their bearings? A new study published in Proceeding of Royal Society A shows that they probably used Iceland spar, a "sunstone".

Some stories make into the newspapers simply because they allow journalists and editors to come up with titles like this one: "Comette family home damaged by egg-sized meteorite."

The article is indeed... poor in someway. But these are the times of resharing (everything, always, with a single click,...). I also read the article and forwarded it to my friends, with a comment like "wow, these guys were lucky! What if they were home?"
But in the end I agree with you. More or less. :-)

Apologies for that, and thank you for pointing it out. I have corrected it now. It was a typo on the post and not the scientific article

It has been a year. On 23 September 2010, I posted for the first time in Dinner Party Science, Nature Network edition. This is also the 50th time I'm writing, so I have two reasons to celebrate.
