Hidden history of prehistoric women's work revealed

Hidden history of prehistoric women's work revealed

Science
Grinding grain for hours a day gave prehistoric women stronger arms than today's elite female rowers, a study suggests.The discovery points to a ''hidden history'' of gruelling manual labour performed by women over millennia, say University of Cambridge researchers.The physical demands on prehistoric women may have been underestimated in the past, the study shows.In fact, women's work was a crucial driver of early farming economies."This is the first study to actually compare prehistoric female bones to those of living women," said lead researcher, Dr Alison Macintosh."By interpreting women's bones in a female-specific context we can start to see how intensive, variable and laborious their behaviours were, hinting at a hidden history of women's work over thousands of years." Elite athletes...

Antarctica's warm underbelly revealed

Antarctica's warm underbelly revealed

Science
This is the best map yet produced of the warmth coming up from the rocks underneath the Antarctic ice sheet. This "geothermal heat flux" is key data required by scientists in order to model how the White Continent is going to react to climate change. If the rockbed's temperature is raised, it makes it easier for the ice above to move. And if global warming is already forcing change on the ice sheet, a higher flux could accelerate matters. The map was made by researchers at the British Antarctic survey and is published in the journal Geophysical Research Letters."The heat coming from the Earth’s interior is important to understand the overall conditions that control the dynamics at the base of the ice sheet and hence the ice flow,” explained Yasmina Martos, currently affiliated to the US sp

Huge quantities of nitrate chemicals from farm fertilisers are polluting the rocks beneath our feet, a study says.Researchers at the British Geological Survey say it could have severe global-scale consequences for rivers, water supplies, human health and the economy.They say the nitrate will be released from the rocks into rivers via springs.That will cause toxic algal blooms and fish deaths, and will cost industry and consumers billions of pounds a year in extra water treatment.In a paper in Nature Communications, the scientists from BGS and Lancaster University estimate that up to 180 million tonnes of nitrate are stored in rocks worldwide - perhaps twice the amount stored in soils.They say this is the first global estimate of the amount of nitrate trapped between the soil layer and the ...
