/The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.
Sunflowers Track the Sun, Like Solar Panels – The behavior was reported in scientific literature in 1898. Now there are studies to understand how the plants do it biochemically and physically. I also liked the picture at the beginning of the article.
Ancient air pockets changing the history of Earth’s oxygen – Ancient air trapped in rock salt shows that earth’s atmosphere contained 10.9% oxygen 813 million years ago….about 300 million years earlier than previously thought. It’s not as much oxygen as in our current atmosphere but a lot of organisms did develop during this time period when there was less oxygen.
Healthy Eating, A to Z – How many of these 26 do you already know?
30 Reason Your Next Car Should Be Electric – I’ve been thinking recently that my next car will probably be electric. It’s good to see that there are a lot of reasons this it is a good idea! Item 29 on this list (kids and grandkids and great-grandkids) is high in my rationale.

The technology is moving forward quickly in the agricultural biotechnology arena. It is challenging to understand it well enough to propose appropriate regulations for public health and safety.
Newly discovered fossils break record, dating back 3.7 billion years ago – Evidence of microbial life found in Greenland (where there are some of the world’s oldest sedimentary rocks). Another article on the same topic from Science Daily can be found here.
Study assesses climate change vulnerability in urban America – Our area got a wakeup call in this arena with the damage to Ellicott City from recent flooding. It happened very quickly, with very little warning. The planning for infrastructure, human populations and local concerns when it comes to climate vulnerability is in its infancy in many parts of the country.
