The researchers discovered that while humans have gained about 30 years of life expectancy over the 20 th century, improvements in overall life expectancy have slowed—and actually declined in ...
Life expectancy at age 1 reached 47 years for the 72% surviving the first year. [34] [35] Early Middle Ages (Europe, from the late 5th or early 6th century to the 10th century) 30–35: A Gaulish boy surviving to age 20 might expect to live 25 more years, while a woman at age 20 could normally expect about 17 more years.
A mutation in the age−1 gene of the nematode worm Caenorhabditis elegans increased mean life span 65% and maximum life span 110%. [82] However, the degree of lifespan extension in relative terms by both the age-1 and daf-2 mutations is strongly dependent on ambient temperature, with ≈10% extension at 16 °C and 65% extension at 27 °C.
In physical cosmology, the age of the universe is the time elapsed since the Big Bang: 13.8 billion years. [1] Astronomers have two different approaches to determine the age of the universe.

Researchers have discovered a megastructure in the Baltic Sea that was likely once used by hunter-gatherers to hunt reindeer nearly 11,000 years ago.
Ming (c. 1498 or 1499–2006), also known as Hafrún, was an ocean quahog clam (Arctica islandica, family Arcticidae) that was dredged off the coast of Iceland in 2006 and whose age was calculated by counting annual growth lines in the shell. Ming was the oldest individual (non-clonal) animal ever discovered whose age could be precisely determined.
The scientists at Colossal are behind the most ambitious projects. This team wants to resurrect the mammoth, the flightless dodo and Tasmanian tiger, an Australian marsupial that went extinct in 1936.
