Gleanings of the Week Ending October 10, 2015

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.

The People and Pueblos of Wupatki National Monument in the 1930s and 40s – The article includes pictures from just after the area became a National Monument. I enjoyed my visit to the monument last winter (see post with photographs here...and the picture below).

A Chart That Shows Where Every Country in the World Gets Its Food – North America is not very self-sufficient! About 90% of our calories come from somewhere else than North America. (Check here for the ‘Degree of Dependence per Country’ table.)

A neuroscience researcher reveals 4 rituals that will make you a happier person – A summary of research findings that can be applied…from Business Insider.

15 Intimate Portraits of Lions – Lions in the wild….pictures from National Geographic.

Aging Workers, New Technology – I was disappointed in the article. The examples seemed lame. For example – better floor mats for jobs that require a lot of standing are good for younger people too! Making technology more intuitive for everyone is important ---- smaller is not always better, and that is true for more than just gaining workers.

How many trees are there in the world? – From Scientific American – the answer is over 3 trillion but we are losing 10 million trees per year.

Martian Life Could Be a Biotech Bonanza – After the announcement of briny water on the Martian surface….what might that mean for the type of life we might find on Mars.

Easy Pumpkin Muffins – I love pumpkin muffins. The recipe I usually use is one that originally was for sweet potato muffins – so if pumpkin is in short supply this year (which I just heard that it might be by Thanksgiving) – substitute cooked sweet potatoes (not the canned ones….the ones from the produce department…bake them) for the pumpkin. Butternut squash will work too.

How to clean and airliner – Maybe I didn’t really want to know this. I’m carrying hand sanitizer from now on when I fly.

Solar-Plus-Battery Systems Can Insulate Customers from Increasing Prices – Solar panels – battery storage – the grid….some ideas about what the future relationship could be.

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.

10 Geological Forms we’ve studied for Years and Still Don’t Understand - Some of the forms we thought we understood….only to discover additional mechanisms played a role (in canyon formation, for example).

Why the FDA Has Never Looked At Some of the Additives in Our Food - In the past 5 decades, the number of food additives has skyrocketed from about 800 to 10,000….and many of them have come to market under the ‘generally recognized as safe’ provision in the FDA safety-review process. Some of them have caused severe allergic reactions or long term health effects. This is a scary aspect to our food system. The article prompted to look more closely at the processed foods I buy and try to skew my food purchases to whole foods that I prepare myself.

Hawksbill Turtles: A Rare Good News Story for a Species on the Brink - Hurray!

This Elevation Map of Mars Makes the Red Planet Much More Colorful - From the German space agency

This 19th Century Art Is Made Entirely Out Of Butterfly Wings - I’d much rather see live butterflies!

A Chart Showing You How Much Water It Takes To Grow All the Food You Eat - Were there any surprises on this chart?  Each circle represents the gallons of water per ounce of a food. I found myself wanting more; I wanted to compare whether soymilk (on the graphic) took more or less water than almond milk (not on the chart).

Exceptionally preserved fossil gives voice to ancient terror bird - The fossil is from South America of a bird flightless that was 4 feet tall and is the most complete ‘terror bird’ discovered with 90% of the skeleton preserved.

Top 5 Interesting Nests in North America - It’s the time of year for birds to be building their nests in our area….and there are some interesting ones in this post.

These Knotted Cords Are a Sophisticated Ancient Counting Tool - The Inca’s knotted counting system…that we still don’t completely understand.

Greatest mass extinction driven by acidic oceans, study finds - A key in the past to understand the impact of ocean acidification.
