Encounters Rising In Southeast U.S. Via WIRED: In France,
Push Comes to SUV: The attacks come as SUV sales are rising in Europe. According to the
Association des Constructeurs Europens d'Automobiles, Europe's leading car
and truck trade association, the share of SUV registrations in European
Union countries has more than doubled, from 3.2 percent in 1998 to 6.5
percent at the end of last year. Sales are flourishing amid gas prices that would shock most Americans. In
France, for example, before prices began to go up last week in the wake of
the Hurricane Katrina disaster, you could easily pay $6.60 per gallon of
gas. At that rate, it would cost more than $210 to fill up a Hummer H2 SUV
and drive it 310 miles, based on the manufacturer's published range at 30
to 40 miles per hour on a hard surface and rolling terrain.

Wings on Every Eyelid: [...] But next year, L'Oreal officials say the company will release
cosmetics that use chemistry and light instead of the pigments, waxes and
oils, used in lower-tech offerings. L'Oreal is working on lip, eye and nail color that it claims will give
customers surrealistic effects they could never obtain with traditional
makeup. [...] Creatures like winged insects and peacocks use chemistry to produce color
for various reasons. A bright blue morpho butterfly might use the effect
to be visible to its peers from far away, while another creature might
employ it as a type of camouflage. [...] Nature achieves this color effect in several ways. One is by
layering uniform-sized troughs of air between a clear, protein-packed
material -- often referred to as cuticle -- which makes up things like an
insect's wings. When white light waves hit the various parts of the
cuticle, they interfere with each other as they pass through it at various
angles. The result can be a variety of brilliant colors that may change
depending on your point of view. A stack of cuticle layers 80 nanometers high will yield blue, while one of
120 nanometers will yield red, Vukusic said. Each material must have a
different refractive index, which refers to the speed at which light
travels through something, in order for the effect to work, he said. To re-create the brilliant colors that appear in nature, scientists vary
the thickness of nano-scale layers of material like mica, liquid crystals
or silica, Pineau said. The makeup will appear white in the packaging, Pineau said, so products
will have to be labeled to let customers know how they'll look on various
skin tones when they're applied. Once applied and exposed to light,
vibrant color will show and change depending on the angle from which it's
viewed.
The spokesman told Wired News that deflating SUV tires does not constitute
a criminal act under the French penal code, according to legal advice the
group obtained from eco-friendly attorneys who back Greenpeace and other
environmental activist groups. The only legal risk they face are civil
lawsuits by the SUV owners, who would have to prove property damage in a
French civil court, the spokesman said.
