The summer solstice occurs at 10:51 UTC on June 21. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is the first day of summer in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere.

The Delta Aquarids is an average shower that can produce up to 20 meteors per hour at its peak. It is produced by debris left behind by comets Marsden and Kracht. The shower runs annually from July 12 to August 23. It peaks this year on the night of July 28 and morning of July 29. This should be a great year for this shower because the thin crescent moon will set early in the evening leaving dark skies for what should a good show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.

As Many Exceptions as Rules: Biology Blog

Using Pain to Stop Pain - Sometimes people use pain to combat pain, as silly as it may sound. The concept of counter-irritation is old. Before we had any idea how it worked or even if it worked, counter irritant uses approached the bizarre. Heart attack and angina pectoris (pain from partially blocked cardiac vessels) often shoot a pain down the left arm. So early physicians decided that if counter irritants were placed on the left arm, they could short circuit the pain as it was sent out but before it could come back to the heart. Read more>>

Chronic insufficient sleep increases obesity, overall body fat in children - One of the most comprehensive studies of the potential link between reduced sleep and childhood obesity finds compelling evidence that children who consistently received less than the recommended hours of sleep during infancy and early childhood had increases in both obesity and in adiposity or overall body fat at age 7.
