Gleanings of the Week Ending August 15, 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.

Is Modern living leading to a ‘hidden epidemic’ of neurological disease? - A study that compared 21 countries between 1989 and 2010 found that dementias are starting a decade earlier than they used to in adults. In the US, neurological deaths in males 75 years old and over have nearly trebled…gone up five-fold for females in the same age range. The rapid increase points to environmental influences. Scary.

A single image captures how the American house has changed over 400 years - The link at the bottom of the article will take you to the full poster. I like history themes that go way beyond what I learned in school (which seemed to be mostly about conflicts and wars).

Deer Management Solutions: It Takes a Village - We have way too many deer in our area. Fortunately I have not been involved in a collision with one….but I see deer grazing near the roads and the occasional carcass from a collision at the roadsides. Our trees and bushes show evidence of deer browsing…we see deer in our backyard. Very few buds on the day lilies survived to become flowers!

Mapping how the United States generates its electricity - Lots of graphics. The first bar chart shows that there is still a lot of coal used for power generation. It accounts for more than 15% of the generating capacity in 15 states. In my home state (Maryland), coal is used for 44% of the capacity.

Global Risks - Richard Watson posts some thought provoking graphics. The subtitle on this one is ‘How would you like your apocalypse?’

Great plains agricultural greenhouse gas emissions could be eliminated - adoption of best management practices (no-tillage agriculture and slow release fertilizer, for example) can substantially mitigate agricultural greenhouse gas fluxes. The challenge is to overcome the cultural and economic barriers (higher cost of slow release fertilizer, new equipment/training required to convert to no-tillage agriculture) to best practices..

A Self-Taught Artist Paints the Rain Forest by Memory and The plants cultivated by the people from the center in the Colombian Amazon - Beautiful and informative work. The second link is for the free eBook. The text is in Spanish…but the drawings are the reason to download it.

Web-based patient-centered toolkit helps improve patient-provider communication - It seems like this is something that should already be in place in most hospitals although I know firsthand that it wasn’t a few years ago when I had a critically ill parent. It is frustrating that it is taking so long for health care organizations to apply data and technology in a way that keeps the focus on care for the patient….and consistent with patient (or their proxy) interaction re that care.

Astronauts Will Eat Space Lettuce for the First Time Next Week - This article is a little dated….they’ve eaten the greens already.

Artist Quits Day Job to Pursue Passion for Beautifully Quilled Paper Art - I like the spiral shape and this art form is all about spiral shapes with colored paper.

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.

Nine superfruits and super seeds to add to your diet - I eat 3 of the 9 frequently (chai, flaxseeds, and blueberries)!  There is only one that I haven’t added to my diet (yet): Acai berries.

There May Be More Water on Jupiter's Largest Moon than on Earth - Subterranean oceans - on Ganymede. It wasn’t so long ago that we assumed that the Earth’s oceans were unique…and now we are thinking that maybe they aren’t.

World's most iconic ecosystems: World heritage sites risk collapse without stronger local management - These sites have importance to world…the researchers argue for stronger local management. That is needed but these ecosystems are connected to other ecosystems are not iconic but may be critical to sustaining these designated iconic areas. We have to start thinking about how we sustain the Earth - worldwide - more often than we’ve ever done before.

Cherry Tree that needs pruningPrune Trees like a Pro - This post has good diagrams. I noticed it this week just as I was thinking about what I need to do first in my yard and decided pruning was high on the list; our cherry and plum both need it.

Archaeologists Uncover Ancient Egyptian Tombs with Stunning Murals - They were found near Luxor. Isn’t it amazing that there are still things like to be found in places that have been intensely searched for over a century? Hopefully they will be preserved in a way that the colors remain as vivid as they are now.

Towels top kitchen contamination hazards list - Ugh! I think I’ll start putting out a fresh towel every day.

The World’s Largest Solar Energy Projects - Some projects from India and California…these are huge installations.

Oncologists reveal reasons for high cost of cancer drugs in U.S. - There is a list of some potential solutions at the end of the article. One that sticks out is to allow the FDA or physician panels to recommend target prices based on the drug’s magnitude of benefit (i.e. value based pricing). Why has our system allowed something other than value based pricing to be the norm? Hurray for the doctors that are standing up for their patients!

10 National Monuments you’ve never heard of - Vacation ideas. I always like to keep these in mind to add to the itinerary of a trip to the area. I’ve been to El Malpais several times. Maybe next time I visit Tucson - Chiricahua will be a day trip.

Chitin, a structural molecule associated with allergy response, is identified in vertebrates - A few weeks ago, I learned that chitin (the material of insects’ exoskeletons) is in the cell walls of mushrooms…and then this article about chitin in fishes and amphibians! And chitin has been shown to be an excellent material for biodegradable plastics!

Coursera - February 2015

Only two courses in progress for me right now! It takes a lot of will power to not sign up for more; there are competing activities this month: travel and classroom-based courses. Here are the two that will keep me busy in February.

Circadian clocks: how rhythms structure life (from Ludwig-Maximilians - Universitat Munchen (LMU) is off to a good start with a mix of history of the research and vocabulary. It’s a topic that is interesting and has lots of implications for health and well-being.

The Land Ethic Reclaimed: Perceptive Hunting, Aldo Leopold, and Conservation (from University of Wisconsin-Madison) started off by having student pick an avatar that reflected their perspective of the course topic. I chose ‘naturalist;’ it will be interesting to see the demographics of the other students in the course. I like the way the instructors are using surveys and probing questions along with the typical MOOC videos, reading list, and discussion forums.

Two courses finished in January:

Recovering the Humankind’s Past and Saving the Universal Heritage (from Sapienza University of Rome) was a more philosophical course than I expected. It included discussion of the science/technology of archaeology and how it developed over time which is what I expected. But the more thought provoking parts of the class were about the concept of ‘universal heritage’ and why it is important; the relationship of wars and destruction of material culture of the past is striking. It happens alongside the human lives lost and plight of refugees in Syria and Iraq.

Origins - Formation of the Universe, Solar System, and Life (from University of Copenhagen) was a very broad course taught by a team of people from the Natural History of Denmark. It was a good update on what has been discovered since I was in college in the 1970s. Scanning Science Daily over the years helps - but it was refreshing to get a fresh update that tied it all together in an organized way.

As usual - I thrive on having some new topics to learn about and Coursera is a prime avenue for that. Hurray for Coursera!

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.

Birding in the National Parks: Return of the Snowy Owls - It looks like this winter will be another one for seeing Snowy Owls in the northern states of the US! There were some sightings in Maryland last winter so I am hoping…

Did Venus Once Have Oceans of Liquid Carbon Dioxide? - Maybe the geological features on Venus (rift valleys, river-like beds, and plains) were may be liquid carbon dioxide rather than water like they are on Earth.

From the Feature Well - This is the summary of 2014 special issues from The Scientist. Looking back at them provides a good review of Biology issues and progress for the year.

The "Rule of 50" Helps You Know When to Give Up on a Book - How do you know when to quit reading a book? Usually I decide via scanning before I every start reading rather than determining ahead of time a number of pages I’ll read before deciding. I can’t remember the last time my scanning failed.

Monarch Butterflies May Soon Be an Endangered Species - The population has declined by 90% since the 1990s. It’s very sad. The agricultural changes in the mid-90s killed the milkweed (food plant for the caterpillars) at the edges of fields. Now there needs to be a concerted effort to increase the availability of milkweed.

The Most Amazing Meteorological and Space Observatories Ever Built - Beautiful and functional architecture from around the world.

Top Planning Trends – 2014 - A look at traffic data on Planetizen…popular tags overall and popular posts for each state. The most popular post for Maryland was about high-rise, mixed-use suburban developments.

Significant link between daily physical activity, vascular health - These type of studies come out frequently…with some nuance defined a little better than before. Hopefully no one is waiting for another study to transition some sedentary to active time every day. Now that I think about it - do these studies prompt people to become more active?

A Look Back at Our Most Popular Photos of 2014 - From the National Wildlife Federation. The very first one (a snowy owl) caught my attention.

National Park Service Launches Website Honoring 22 World Heritage Sites in the United States - Did you know that there are 22 World Heritage Sites (a UN designation) are in the US?  Most of them are National Parks…but now all. The list can be found here.

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.

2014 in Numbers: Huge Valuations, Shocking Security Stats, and a Big Climate Deal - Factoids for the year. The last one was the one that caught my attention the most 4.4 zettabytes = all digital information in the world….and it is growing by 40% per year!

2014: An amazing year in space exploration - Philae, Orion, SpaceX Falcon 9, and Mar Rover Opportunity setting off-Earth, off-road distance record.

2014 in Materials: Rhubarb Batteries, the Gigafactory, and Printing Body Parts - It’s hard to keep up with all the innovations. How fast can any of these really get to market and be affordable?

Researchers create method that recovers high value metals for industries while protecting the environment - A step in the right direction. Hopefully the metals recovered will be valuable enough to drive the technology from the lab to application.

The Year in Pathogens - Ebola tops this list from The Scientist.

2014 in Computing: Breakthroughs in Artificial Intelligence - Seeing the aggregate for the year….2014 was quite a year for AI in a number of areas.

2014 in Energy: The Year in Energy and Climate Change - Increased urgency of warnings….only slow progress. Frustrating.

Young entrepreneurs innovate in green energy with an in situ organic waste digester - Kudos to the young Mexican entrepreneurs….and the company that is implementing their innovation.

American cities are many times brighter at night than German counterparts - The US could learn from German….and help us all see more stars in the sky too.

Social Media Sites Offer a Nice Sampling of Winter Scenery in Parks - Winter brings a different perspective.
