Researchers for the Massach...

Researchers for the Massachusetts Turnpike Authority found over 200 dead crows near greater Boston recently, and there was concern that they may have died from Avian Flu.

A Bird Pathologist examined the remains of all the crows, and, to everyone's relief, confirmed the problem was definitely NOT Avian Flu. The cause of death appeared to be vehicular impacts.

However, during the detailed analysis it was noted that varying colors of paints appeared on the bird's beaks and claws.

By analyzing these paint residues it was determined that 98% of the crows had been killed by impact with trucks, while only 2% were killed by an impact with a car.

MTA then hired an Ornithological Behaviorist to determine if there was a cause for the disproportionate percentages of truck kills versus car kills.

He very quickly concluded the cause: When crows eat road kill, they always have a look-out crow in a nearby tree to warn of impending danger.

They discovered that while all the lookout crows could shout “Cah”, not a single one could shout “Truck.”

Walter Noddack

Died 7 Dec 1960 at age 67 (born 17 Aug 1893).Walter Karl Friedrich Noddack was a German chemist who discovered the element rhenium (Jun 1925) in collaboration with his wife Ida Tacke. In 1922, he began a long search for undiscovered elements. After three years, the careful fractionation of certain ores yielded element 75, a rare heavy metallic element that resembles manganese. Named rhenium after the Rhine River, it was the last stable element to be discovered. Noddack is also remembered for arguing for a concept he called allgegenwartskonzentration or, literally, omnipresent concentration. This idea, reminiscent of Greek philosopher Anaxagoras, assumed that every mineral actually contained every element. The reason they could not all be detected was they existed in too small quantities.
