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.

Quiz: Can you tell these 16 cities by their skylines? -  I got 12 of the 16!

The Great Tuskers of Matusadona - Matusadona National Park in northern Zimbabwe….with lots of elephants and an organized anti-poaching group that (so far) appears to be sustaining the park wildlife.

Supreme Crispy Quinoa Vegetable Burgers - I don’t think I would actually eat this on a bun - since I general decide that I don’t like buns well enough to justify the calories. But I am always on the lookout for other ways to use quinoa since its nutritional profile is so terrific (and it tastes food too)…definitely worth the calories.

An El Nino connection to the floods in Oklahoma and Texas? - Map and narrative about El Nino and its impact on US weather patterns (using recent weather as an example).

These Are the Most Distinctive Popular Foods in Every State - Does it make sense for your state? Crab Cakes is listed for Maryland and that sounds about right.

See This Baby Flamingo Take Its First Few Steps - I knew that baby flamingoes were white (had picked up that bit of trivia somewhere along the line) but I hadn’t ever seen one. I was surprised at how big its legs were. The adult flamingoes seem very attentive to the baby too.

Insane Solar Jobs Boom About To Get $32 Million More Insane - Renewable energy stretching toward the goal of becoming competitive with fossil fuels.

There are No Shortcuts to Birding Nirvana - I was surprised that the Merlin app (from The Cornell Lab of Ornithology) was not mentioned. Maybe because it only includes 400 North American birds. It has the advantage that it is very easy to use even for new birders. I like it.

Designed for the Future: Practical Ideas for a Sustainable World - Take a look at the gallery (link below the picture). These are structures that exist - not drawings or plans.

Hidden Lead in Your Home - It isn’t just old lead pain on walls…there are more sources.

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.

How to Make Fresh Ginger-Lemon Tea - I modified the recipe a bit - made a slurry of the ingredients (with less water) in a smoothie maker then boiled it. After cooling - I strained the liquid into ice trays and am savoring a few cubes at a time for ginger-lemon flavored water.

No-Bake Breakfast Cookies - An option to try instead of purchasing breakfast bars? This way - I would know exactly what is in them.

Baroque organ performance of works by Johann Sebastian Bach - Listen to the music….and watch how a German baroque organ looks and is played!

This Is How Fast America Changes Its Mind - Some historical perspective…but there are always portions of the population that do not change their mind for many years afterward.

As the river rises: Cahokia's emergence and decline linked to Mississippi River flooding - I have visited Cahokia…and realized there is still a lot to learn about the site.

The Lake Mead Water Crisis Explained - The drought is causing the late to drop lower than it has ever been. At some point the lake will not be able to provide the water allocation to Nevada and California and Arizona…and it won’t generate as much electricity either.

Can Elon Musk's battery really cut your power lines? - The technology may or may not be ready for prime time and cost effective…..but I cheer that the discussion is happening and hope that we are reaching a tipping point where the majority of people in the US realize that we need to move off fossil fuels as fast or faster than the rest of the world or we will lose whatever competitive edge our society has at present. And another story about solar power policy: MIT says solar power fields with trillions of watts of capacity are on the way.

The first self-driving 18-wheeler hits the highways - The Nevada Department of Motor Vehicles granted it a license to operate on public roads in the state! It is self-driving but not driverless. Drivers are still required for exiting the highway, on local roads and in docking for making deliveries.

A Brief Guide to Atmospheric Pollutants - A nice summary (click on the graphic to enlarge) from Andy Brunning at Compound Interest.

Record global carbon dioxide concentrations surpass 400 parts per million in March 2015 - Not good. This article provides a history of how and where the 400 ppm gets measured.

A Visual Guide to Chemistry Glassware - A vocabulary lesson in glassware!  Probably everyone knows the difference between a test tube and a beaker…but what about a conical flask and volumetric flask?

From soda bans to bike lanes: Which 'natural experiments' really reduce obesity? - Which changes have made an impact? Studies that included longer follow-up periods after a change showed stronger results. Two examples of changes with strong impact were trans-fat bans and active transportation infrastructure improvement.

50% Driving Ban for Paris Due To Air Pollution - Weather conditions in Paris cause spikes in air pollution this time of year. We normally thin of the larger cities in India and China having the worst air pollution problems. The World Health Organization estimated that air pollution contributed to the deaths of 7 million people in 2012…so it is not an insignificant issue for the world.

Science Photographer Reveals Beauty of the Microscopic World - Manipulation of light through the microscope: transmission, differential interference contrast, optical staining, or dark field contrast.

Adapting to climate change will bring new environmental problems - Can we adapt in a sustainable way…or will our adaptation be short-sighted - and bad for the planet in the long term?

Archaeologists discover Maya 'melting pot' - Evidently mobile groups of hunter gatherers came together with settled groups for construction projects and public ceremonies --- they interacted much more than previous thought. They eventually became more uniformly sedentary.

Genome Study Predicts DNA of the Whole of Iceland - The DeCode project has collected enough full DNA sequences from Icelanders to extrapolate to the whole population (because the people are related). From this analysis, they know that 2,000 people in Iceland have the BRCA2 gene….but cannot tell them. The ethics associated with new technology is complex. In this particular case there is a “right ‘not to know’ of genetic hazards.” With more and more genome data being collected - other nations will soon have the same issue Iceland is facing now.

The Last 200 Years Of U.S. Immigration In One Chart - Click in the upper left corner to enlarge the plot. The overall trend is as interesting as where people came from. World War II had quite an impact while World War I did not.

SolarCity to build its own power grids - The market for solar technology seems to be developing very quickly. There are so many more options now than there were 5 years ago. When will the tipping point come…when more people will have solar - or some form of renewable energy where they live and work.

Compulsive Behavior Sells - Habit-forming technology….a little scary. How quickly will people train themselves to realize that it is happening?

Millions of Mutated Mosquitoes Could Be Unleashed In Florida—On Purpose - There is concern that tropical diseases like Dengue and Chikungunya will become more common in the US as the climate becomes warmer. Reducing the number of mosquitoes that spread the disease may become a priority and there biotech firm Oxitec has experimented in the Caymen Islands and Brazil with GMO mosquitoes that suppressed the population there by 96%.

Swarm of microprobes to head for Jupiter - The probes will burn up in Jupiter’s atmosphere was send a mass of data for 15 minutes. A lot will be learned about the atmosphere of the planet.

Assateague Island National Seashore Turning 50 This Year - Chincoteague/Assateague is my favorite place on the Eastern Shore of the Chesapeake Bay….I’ll keep an eye out for extra activities that celebrate its 50 years as a National Seashore.

Two Graphs Highlighting Growth Surge in US Solar Market - With oil prices lower, will the trend continue in 2015?

Food Industry Drags Its Heels on Recyclable and Compostable Packaging - The food industry - particularly the fast food industry - is definitely not trending toward sustainable practices (with the possible exception of McDonald’s and Starbucks….and do we really need K-cups anywhere?

A Stunning 3D Cross-Section of Greenland's Ice Sheet - Made using ice cores and ice penetrating radar technologies. Watch the video to understand how it was done. There are three distinct periods of climate reflected in the Greenland Ice sheet.
