In which Parisist keeps an open mind, but not so open that our brains fall out.

• The teeny and the tiny alike are on exhibition through September at the Nano Expo, at the Cité des Sciences et de l'Industrie (where the dome above can be found).
• This past Thursday, French space agency CNES released its UFO files. France was the only country in the 80's and 90's to retain paid UFO investigators, according to Wikipedia. On Thursday, bouncers were needed at the space agency headquarters to keep the freaks out, and the CNES website apparently crashed three hours after the data were posted.
• A mammoth skeleton and other paleontological curiosities are to go under the hammer at Christie's Paris branch next month. Other goodies include a Russian meteorite and a private collection of trilobite fossils.
• A new study finds that sniffles and eczema [fr] are the most common allergy-releated ailments among Parisian infants. The study found that in 22% of cases, at least one parent admitted to smoking at home. Pet dander and chemical pollutants were also found to be significant irritants.
• Archaeological work on the medieval keep at the Château de Vincennes is wrapping up [fr] after nine years of digging and restoration. The keep will open to the public next May.
