Welcome dear science-aware reader, I’ve been slogging through The Climate Book created through the efforts of Greta Thunberg. It is an astounding collection of 84 short ‘essays’ by scientists, economists, visionaries, philosophers, and respected authors. 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

These animals are extinct but efforts are currently underway to “bring them back.” In each case, researchers are compiling the complete genomes of the extinct animals using … Read more

Happy New Year. Thank you for joining me today.

Hello again, dear science fan, No one – arguably – knows more about ghost hunting than Kenny Biddle. At this year’s SkeptiCal, he shared stories from his ghost-hunting forays, including the techniques and the electronic instrumentation he used. Some years ago, however, Biddle did a turn-around, climbed out of the ghost-hunting rabbit hole, and became a … Read more

Happy Labor Day dear reader, I recall the first time i saw a geochron clock on the wall of my hometown bank. Instantly i knew where in the world there was sunrise, sunset, night, and day. It lifted me for several minutes from living in a town in California with a few thousand others to … Read more

Hello again science fans, Daniela Rößler (‘ß’ is a double-s symbol used in Deutschland) has gathered fascinating data suggesting that jumping spiders might actually dream while sleeping. ¿Sleeping spiders? Well, yes. Just about every animal has been observed in behaviors that seem to indicate sleep. REM (rapid eye movement) sleep is associated with dreaming in humans, … Read more
