Things I learned this week

I learned that:
• There is a shortage of helium, a crucial ingredient in MRI machines, cryogenics, high-energy accelerators, arc welding, silicon wafer manufacturing, and party balloons. The reasons are complicated.

• Canada’s Aboriginal population is younger and has a high fertility rate compared to the non-Aboriginal population. This will likely produce growth in the relative numbers of Aboriginal people.

• We are not eating enough dirt. When most people ate vegetables pulled from their own gardens, their diet included pathogens and benign microorganisms that protected them from food allergies and autoimmune disorders, which have skyrocketed in the age of shrinkwrapped veggies.

• Voices that "carry" contain a pitch with a frequency around 3,000 beats per second, about the same frequency as that of fingernails scraping a chalkboard.

• The Maldives, an island nation long expected to be the first casualty of rising sea levels due to global warming, is now working with a Dutch company to build floating replacements to provide sanctuary for its citizens. The artificial islands will be anchored to the sea floor.
How about that?
