Obstructed labor in humans
A mathematical model of human obstetrics finds that weak selection for a large newborn, a narrow female pelvis, or both factors might account for the large number of cases in which newborn size and maternal pelvis dimensions result in obstructed labor. -

Plant diet of early humans
At the mid-Pleistocene archaeological site Gesher Benot Ya‘aqov, Israel, researchers found 780,000-year-old botanical remains of 55 food plant species that likely complemented a diet of aquatic and terrestrial animals, findings that suggest a varied plant diet, staple plant foods, and the use of fire in food processing. -

Geoengineering without ozone loss
Researchers report a solar geoengineering method based on the injection of calcite particles, rather than the more frequently suggested sulfuric acid, into the stratosphere to mitigate the effects of climate change, and suggest that this method might help cool the planet while simultaneously healing the ozone layer. -
