PULLMAN, Wash. – Zebrafish exposed to very low levels of methylmercury as embryos not only passed on toxic effects of the chemical exposure to their offspring, but also to the third generation, according to a study that investigated both epigenetic changes – chemical modifications to the DNA – and abnormal neuro-behavior associated with exposure.

PULLMAN, Wash. – When I was a younger and more sprightly woman, I spent part of my life investigating unusual hot springs in rural California.

The Jewett Observatory is inviting visitors to bundle up and stop by to enjoy a night of stars at the observatory this Saturday, October 28, at 8 pm. At this “Star Party” you can view the cosmos and hopefully catch a glimpse of Mercury and Jupiter in the twilight glare from the sun. The Observatory will also be open on All Hallow’s Eve (Oct. 31), from 6 to 8 pm. The dome will be open and candy will be available. The viewings will be cancelled if it is a cloudy night.The Jewett Observatory is located off of Chinook Drive, across from the equine track.
