For example, a claim has an ICN of 1114100351480. The third and fourth digits of the ICN are 14, indicating the claim was received in calendar year 2014. The fifth, sixth, and seventh digits of the ICN are 100, indicating the claim was received on the 100th day of the calendar year. As such, the claim was received by Medicare on April 10, 2014.
Until recently, life on Earth was said to have begun 3.5 billion years ago, a date originally based on curvaceous, worm-like strings of microfossils â tiny remains of bacteria, protists, fungi, animals, and plants five-thousandths of a millimetre in length, found in the ancient rocks of Western Australia's Marble Bar.
Image caption Life would face challenges on Mars today, but billions of years ago conditions might have been better. Life may have started on Mars before arriving on Earth, a major scientific conference has heard. New research supports an idea that the Red Planet was a better place to kick-start biology billions of years ago than the early Earth was. The evidence is based on how the first molecules necessary for life were assembled. The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock. Details of the theory were outlined by Prof Steven Benner at the Goldschmidt Meeting in Florence, Italy.
