Pigeons can identify breast cancer in mammograms just as well as human experts can.
Scientists did an experiment and taught pigeons to differentiate between the slides of patients with breast cancer and those of healthy people. The birds are able to accurately sort the slides by categories and recognize which of them shows cancer and which doesn’t.

#10 this is not only in paris so, but in most of europe (I don't exactly know if there's a country where it's different). If you arrive on crossroads and there is no sign or traffic light, the car on your right goes first, the car on your left has to wait. If there are 4 cars at the same time, someone has to give up his right to go first to the car on your left. That's why this is mostly used in rural areas or in suburbs to slow down traffic.

Jacobus,
"Car on the right has the right-of-way" is true in the US as well - look it up - but the importation of a culture with no rules has badly eroded the observance of this standard.

#10 I wish in North America would be the same. It should be yield sign instead, and may be main road sign. When I moved to Canada, I was stun to see "stop" on almost every corner.

Edmund,
A gallon is a part of a binary volume measurement system. It is very efficient (ask your computer, which spends way too much time converting to base-10). Volume is also correlated with the weight of water on Earth, "A pint (1/8 gallon [volume]) is a pound (16 ounces [force]) all the world round".
The French had a chance to make the Metric system similarly grounded in the world we live in, but they hated the English I guess so they decided to go with a less useful, arbitrary standard instead.
