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

The privileged white male Declaration signers accepted this passage:  “… merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.” Six of … Read more

It was given knowledge that a musk ox is protected from concussive brain injury by having an intracranial air pocket and a very broad horn. Research now shows they suffer from chronic traumatic encephalopathy – just like boxers and American football players – and may suffer some degree of dementia. The researchers surmise that mild dementia in … Read more

The U.S. Constitution as of 1791 held that: Slavery was legal; For census purposes, slaves counted as ⅗ of a person; Slaves and women were not entitled to vote; People had the right to bear muzzle-loaded firearms. The only “Arms” covered by the Constitution’s 2nd Amendment were single shot weapons that had to be manually reloaded … Read more

Recently your SciSchmooze has come all too often with ‘cosmic’ images: Sunday’s lunar eclipse, a solar eclipse by Phobos, low temperatures of the James Webb Space Telescope, Hubble’s image of Earendel, etc., etc. This week i was planning on an image of something closer to home, but along came the image of the supermassive black hole that … Read more
