Clay Seals May Support Bible Story

December 22, 2014 | by Associated Press, Janet McConnaughey | News | Comments

Impressions from ancient clay seals found at a small site in Israel east of Gaza are signs of government in an area thought to be entirely rural during the 10th century B.C. This could indicate that Biblical accounts of David and his son Solomon described real kings rather than the backwater chieftains considered more likely by some archaeologists.

Sedentary Lifestyle Made Human Bones Lighter

December 23, 2014 7:00 am | by American Museum of Natural History | News | Comments

Research has shown that modern human skeletons evolved into their lightly built form only relatively recently— after the start of the Holocene about 12,000 years ago and even more recently in some human populations. The work revealed a higher decrease in the density of lower limbs, suggesting that the transformation may be linked to humans' shift from a foraging lifestyle to a sedentary agricultural one.

Why Isn't the Solstice the Coldest Winter Day?

December 23, 2014 7:00 am | by Inside Science News Service, Katharine Gammon | News | Comments

Santa Knows if You’re Sleeping, Put Down the e-Reader

December 23, 2014 7:00 am | by Penn State | News | Comments

You may think your e-reader is helping you get to sleep at night, but it might actually be harming your quality of sleep. Exposure to light at night suppresses release of the sleep-facilitating hormone melatonin and shifts the circadian clock, making it harder to fall asleep at bedtime. The devices emit light that is short-wavelength-enriched light, which has a higher concentration of blue light than natural light.

December 22, 2014 9:14 am | by Univ. of Bristol | News | Comments

There has been a steady increase in the number of children who become short-sighted over recent decades. One aspect of modern life that may be partly to blame is the reducing amount of time we spend outdoors during childhood. But, new research suggests that children with low levels of vitamin D in their blood are not at increased risk of developing myopia.
