Photonic Ink Changes Color On Command
An anonymous reader submits "According to Nature's report : "A new ink changes colour at the flick of a switch." It now named Photonic Ink, or P-Ink. "P-Ink's iridescent colours depend upon a process called diffraction." "To make the colour of the ink tunable" the team led by Geoffrey Ozin "packs a polymer gel between its stacked spheres" which can change size "when it is soaked in solvent and shrinks when it dries". In addition, it "conducts electricity", and "altering the voltage tunes the ink's colour smoothly through the spectrum." more detail also can found on Advanced Materials."
FUCK FIRST POST! I didn't hit 20 seconds TWICE! I HATE SLASHDOT! NILES HATES SLASHDOT!
I hate slashdot. Kill it now.
RECTUM - With a dog in perfect health the anus should be small, close, firm
and entirely retracted. Should the fundament protrude, or if it presents a
sensible projection to the touch, the animal's digestion is not good. Should
the orifice be enlarged the position is worse and it will not be long before
cracks and ulcers may be detected upon the borders of the opening, these
being at a later period constantly moistened by an unctuous fetid discharge.
Should the lips of the orifice be gently pulled aside, the inward section of
the membrane will show a bright scarlet colour, which is moistened with a
watery fluid. During health the animal's bowels are never relaxed and the
straining it employs to expel its faeces is sufficient to suggest the injury
to which the rectum is exposed. If the body be delicate, bone and other hard
substances pass through it without affecting the powers of assimilation;
they become hard and sharp projections when surrounded by, and fixed in, a
solid mass characteristic of the excrement of the dog. Hence a pointed piece
of bone, projecting from a firm body, is liable to lacerate the tender and
soft membrane over which it would have to be propelled. The anus of a dog is
often as indicative of the general state of the dog's body as is the tongue
with man.
