The art of the interchange - Where megahighways cross….17 interchanges seen from above.

Mammoths killed by abrupt climate change - Rapid warming….rather than sudden cold…appears to have been the cause of massive extinctions in the past. The research is based on DNA analysis of ancient DNA and improved statistical processing of the data.

Dumbledores and Bumblebees - Take a look at the great pictures…then read the article. Did you know that Dumbledore takes his name from an Old English term for the bumblebee? And this is an upbeat article…pointing to ways individuals can help out the bumblebees! There are about 250 species of which 25% are in that ‘steep decline’ category.

Explore 25 Lost Cities with This Video - How many of these lost cities have your heard about before?

U.S. breast milk is glyphosate free - Good to know.

Summer Bugs that can Bite You - A summary from a medical perspective. I was disappointed that they didn’t suggest Epsom salts soaks and/or baking soda to reduce discomfort. I often find the calamine lotion and/or hydrocortisone cream ineffective for bites - particularly chiggers.

Sea Otters Use Tools and Archaeologists Are On the Case - ‘Tool making’ used to be thought of as a uniquely human trait…but now there are other animals that make tools. In the Sea otter’s case - they use rocks as tools to break open shells of their food.

Boosting older adults' vision through training - The core of the message from the research was positive but it was frustrating that the next steps were all about more research. If the initial research finding holds - then why is there not already a strategy activity to think through how vision training could be delivered to larger numbers of people at low cost.

By separating nature from economics, we have walked blindly into tragedy - We live in complex world…making decisions based on simplifying assumptions that ignore the environment or economic or social aspects are perilous.

New research into materials for tooth fillings - The composite that is most common right now is problematic because it requires adhesive to bond to the tooth, needs to be illuminated with a lamp to harden, and needs to be replaced more frequently. A new material - glass ionomer cement - may be the filling material of the future.
