It’s estimated that 12% of human pregnancies begin as multiple pregnancies, but less than 2% end that way. What happens to the other embryo? Recall that identical twins occur when one egg splits into two and results in two embryos. But sometimes one of the embryos simply vanishes, leaving only one to develop to term.
In 1984, radiation worker Stanley Watras set off an alarm that detected radiation exposure. A quick examination revealed Watras was not physically carrying any radiation source; the explanation was much more insidious: His body had absorbed large amounts of radon gas from his house’s basement. We tend to believe radiation is relatively rare and dangerous, but
Awhile back, I had a great idea for a short story. I put my best work on paper, then sent it to the Bewildering Stories website. They rejected it. But after two rewrites, it was eventually accepted and published in Issue 864 (http://www.bewilderingstories.com/issue864/help_friend1.html). The short story turned out so well, I just kept writing. Forty-two
Travel is good, although with the COVID virus rampant, travel is also a pain. That goes double for international travel. Having been on the road for the past two weeks for the first time in over two years, I got a firsthand look at what travel during a pandemic entails. I visited the United Kingdom,
Of all the COVID adaptations, one of the more imaginative is the community refrigerator. The idea is quite simple — put a fridge on a street corner, stock it with surplus food, and let people help themselves under the motto “take what you need, leave what you can.” Since the start of the pandemic, these
Catching up on my reading, I ran across an amazing story from the 9/11 tragedy. When the Twin Towers fell, people began running for their lives. Since this was the tip of lower Manhattan, people on the south side were quickly trapped at the waterfront. Their salvation came from the flotilla of more than 150

The Cala Gonone Aquarium in Sardinia, Italy is reporting a female smoothhound shark has given birth despite having been in a tank with only another female for the past decade. As reported by Newsweek (https://www.newsweek.com/baby-shark-born-all-female-tank-could-scientific-first-1622272), this may be a scientific first for this species. Not that this phenomenon is completely unknown. It even has a
Listening to the media coverage of the Iraq withdrawal, one of the most heartbreaking stories was the interview with the widow of the last servicemember killed. This had an special impact on me because twice in my military career, I had to tell families that they’d lost a loved one. When a death or injury
What is the upper limit of human lifespan? At one time, reaching the age of 100 was considered to be a remarkable achievement. Yet by 2050, the United Nations estimates there could be as many as 3.7 million centenarians in the world, a major increase from just under 600,000 today. (I hope I’m included; I would be
