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
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.

In my younger years when I was a Boy Scout, my small hometown had a street fair for a weekend one year. Our scout troop, in a moment of temporary insanity, decided to offer a goldfish booth as a fundraiser. I’m sure you’ve seen these somewhere before — toss a Ping-Pong ball at a table
No, this is not a joke. Animals of many species cross our highways, frequently with tragic results. There are over one million collisions between vehicles and large animals each year in this country. The predictable result is hundreds of deaths to both us and the animals, not to mention property damage running into the billions
There are some aspects of our lives that we always take for granted. For example, having maple syrup, which was first made by the Indigenous peoples of North America long before Europeans arrived. Its availability has made it a breakfast staple, as well as being an important part of the economies of the Northeastern United
How does your energy generation go green when you have a limited amount of land, and much of that is below sea level? You can design a floating solar park! The obvious candidate for such an innovation is The Netherlands. And they’ve done it! Trust the Dutch to think outside the box. The Dutch company
How did the First of April become April Fools’ Day? There are a number of origin stories, but here is one that we know isn’t true. This version originated with Joseph Boskin, a professor of history at Boston University. Boskin claimed the idea of designating a day for general foolishness came from the reign of Roman
On August 20, 2007, a 12-year-old girl spotted a blue-and-white running shoe on a beach of British Columbia’s Jedediah Island. Inside was a sock, and inside the sock was a foot. No other body parts, just one foot. Over the next 12 years, a total of 15 feet were found ashore in the area around
