The loss of a father due to death, divorce or jail is associated with children having shorter caps on the ends of their chromosomes, according to a study that points to a possible biological explanation for health problems often encountered by kids with absent dads.
The protective caps known as telomeres shrink with age, and are also thought to erode with extreme stress.
At age 9, kids who had lost a father had 14 percent shorter telomeres than children whose dad was still involved in their lives, researchers report in Pediatrics. Death had the biggest impact, and the association was stronger for boys than for girls.
Thousands of years before the ancient Roman Empire, the north African civilization of ancient Egypt was leading the way in the fields of art, architecture, and engineering. Many of their preserved creations can still be seen today in museums across the globe. In addition to sculptures, jewelry, and headdresses, some everyday objects can be viewed as well. The Metropolitan Museum of Art holds a beautiful painter’s palette that dates back to 1390-1352 BCE.
Archaeologists have discovered the world’s oldest known cave painting: a life-sized picture of a wild pig that was made at least 45,500 years ago in Indonesia.
The finding described in the journal Science Advances on Wednesday provides the earliest evidence of human settlement of the region.
Co-author Maxime Aubert of Australia’s Griffith University told AFP it was found on the island of Sulawesi in 2017 by doctoral student Basran Burhan, as part of surveys the team was carrying out with Indonesian authorities.
The Leang Tedongnge cave is located in a remote valley enclosed by sheer limestone cliffs, about an hour’s walk from the nearest road.
The 19th-century whale hunt was a brutal business, awash with blubber, blood, and the cruel destruction of life. But between the frantic calls of “there she blows!”, there was plenty of time for creation too. Jessica Boyall explores the rich vein of illustration running through the logbooks and journals of Nantucket whalers.
The first Neanderthal face to emerge from time’s sarcophagus was a woman’s. As the social and liberal revolutions of 1848 began convulsing Europe, quarry workers’ rough hands pulled her from the great Rock of Gibraltar. Calcite mantling her skull meant that, at first, she seemed more a hunk of stone than a once warm-blooded being, and obscured her decidedly odd anatomy – massive eyes, heavy brow ridges and a low, long cranium. While monarchies fell and serfs breathed the sweet air of freedom that year, it would take another decade for human origins as a science to begin its own overthrow of the old world order. The first recognised Neanderthal was a different skull-top, blasted from the Feldhofer cave in Germany in 1856, just two years before Alfred Russel Wallace and Charles Darwin presented their theory of evolution by natural selection.
However, the Forbes skull, as the earlier Gibraltarian find is now known, had to wait until 1863 for her turn in the limelight. Catching the eye of a visiting doctor with anthropological interests, she was packed aboard a ship bound for Britain, then introduced to none other than Darwin (who reportedly found the experience ‘wonderful’). While her overall anatomy excited huge interest, her potential sex was little considered. Instead, the world-wrenching significance of the Forbes and Feldhofer fossils was the first proof of another kind of ancient human entirely.
