Hello again dear SciSchmooze reader, In the U.S. 69% of adults believe that angels are real, and 41% believe that extraterrestrial UFOs are regularly seen.

Hello again, dear reader, SPACE While we were Earth-bound last week, 17 out of Earth’s 8 billion people were in orbit – a new (if soon-to-be-exceeded) record. ¿How high an orbit?

SPACE Learned geophysicists years ago concluded that Mars has a hot liquid inner core, unlike Earth with its hot solid inner core. They calculated that Mars’ gravitational pressure is insufficient to make molten iron solid, as is the case with our home planet. … Read more
Welcome again, I get such good feedback from so many of you that i often think of you as colleagues.

The book has 5 sections: – How Climate Works– How Our Planet is Changing– How It Affects Us– What We’ve Done About … Read more
Welcome dear science-appreciative reader, When Avian Influenza H5N1 is detected in one chicken on an egg farm, it and all of the tens of thousands of other chickens there are destroyed. Over 50 million birds in the U.S. were destroyed this way last year. ¿Why not vaccinate chickens? It isn’t expensive. It’s because eggs and chickens sold … Read more
