Hypo-Allergenic City

As many as thirty percent of Americans have allergies, and most of the pollen they are affected by comes from trees planted nearby. Cities could relieve sufferers by planting low-pollen street trees.

Cities could reduce their pollen count by planting street trees that produce very little of it, writes Thomas Leo Ogran, author of the book Allergy-Free Gardening. American cities weren't always hotbeds of springtime sneezing. Rather, he writes, they became much more allergenic in the 60s and 70s when Dutch elm disease killed many of the low-pollen American elms that lined the streets in cities across the country. Their replacements were highly allergenic, and are responsible for the wheezing, drowsiness and watery eyes that we now associate with this time of year.

Surprising Science
  • Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
  • These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
  • The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.
