You’ve probably heard that if you drop a piece of food on the floor and pick it up within five seconds, it’s okay to eat because germs hadn’t had enough time to get to it. (Personally I’ve always used a three-second rule, with a five-second corollary for chocolate.) Is this true? Scientists are actually beginning
You don’t have to be big or technologically sophisticated to alter the environment. Recently I ran across a science piece about the impact of earthworms in North American forests. I have always thought earthworms were good — they aerate and enrich the soil. But according to a new study published September 3, 2016 in the
You’ve seen them in parking lots — donation bins. It’s a great way to dispose of old clothes. Especially with the holidays coming up, it’s also a good way to donate to charity. Or is it? The BBB Wise Giving Alliance, an organization that rates charities (http://www.give.org/), has some useful information in the cover story
I know crazy things can happen during football season, but this study really surprised me — Two economists at Louisiana State University (LSU) have analyzed juvenile court decisions made between 1996 and 2012. They found that for judges who attended LSU as undergraduates, a football loss led to disproportionately stiffer sentences. If the loss was
A belated birthday greeting to Tarzan, who debuted on August 27, 1912 in the pages of All-Story Magazine. The title was Tarzan, King of the Apes, and the story was written by Edgar Rice Burroughs, who had failed at a whole list of occupations before he tried writing. His inspiration came from the pulp magazines
Have you heard the latest from the world of science? We are entering a new epoch. For some 12,000 years, we have been living in the Holocene era, a stable and relative warm climate that has allowed the present world to develop. But on August 29, a working group of scientists at a meeting of
In this very unusual political year, the electorate seems as polarized as it’s been since the Civil War. Many people feel dire things will happen if their candidate is not elected president. Which brings up the question, how much difference does a president make anyway? Remember our Founding Fathers distrusted government at least as much
Whenever I teach in middle school, it’s not unusual to see girls with babies. Not real babies (thankfully), but realistic dolls that mimic a child’s needs. Their job is to care for this doll as if it was alive, including middle-of-the-night demands. I don’t know how long the assignment lasts, but it’s a mandatory part
We have come a long way in this country from our founding when we were being led by an exclusive group of white male landowners. There has been so much progress that accounts of how social conditions used to be can be quite jarring. In just my lifetime, we’ve gone from racism being an integral
There’s a lot about this world we still don’t understand. That includes theoretical physics (especially for me). Scientists recognize four fundamental natural forces. They are gravity, electromagnetism, and the strong and weak nuclear forces found inside atoms. Could there be a fifth? Basically, maybe. On August 14, 2016, physicists at University of California, Irvine (UCI)
