Earth’s water [likely] piggybacked on asteroids, not comets

Whether comets or asteroids were the source of Earth's water has long been the subject of debate. Now an analysis of the composition of meteorites suggests the water did not originate in the outer solar system, a finding that favours asteroids as the vehicle for its arrival.
Water Ice Found on the Surface of an Asteroid for the First Time
An asteroid circling the sun between the orbits of Mars and Jupiter has for the first time been shown to harbor water ice and organic compounds. Those traits had been associated with comets, which spring from colder, more distant reservoirs in the outer solar system, but not their asteroidal cousins. The finding supports the notion that asteroids could have provided early Earth with water for its oceans as well as some of the prebiotic compounds that allowed life to develop.

That time of the month … to shop
If cramps, mood swings and ice cream binges are what come to mind when you hear the hackneyed phrase that time of the month, think again. Researchers at Concordia University are taking a new look at the menstrual cycle by investigating what these monthly hormonal fluctuations mean when it comes to consumer consumption.

Fruitful news from tart cherry studies
Take two slices of cherry pie and call me in the morning.
OK. That's not quite the advice doctors are wont to give. But it might make at least a sliver of sense.
Cherry pie contains the same sort of anti-inflammatory compounds as aspirin and other non-steroidal anti-inflammatory drugs — at least the cherries do. They're tart, or sour, cherries, which, as far as is known, contain more of these anti-inflammatory compounds than any other food, says Dr. Kerry Kuehl, assistant director of the Human Performance Laboratory at Oregon Health and Science University in Portland.
