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.”

Frederick Soddy

Died 22 Sep 1956 at age 79 (born 2 Sep 1877). English chemist and physicist who received the Nobel Prize for Chemistry in 1921 for investigating radioactive substances. He suggested that different elements produced in different radioactive transformations were capable of occupying the same place on the Periodic Table, and on 18 Feb 1913 he named such species "isotopes" from Greek words meaning “same place.” He is credited, along with others, with the discovery of the element protactinium in 1917.
