Gleanings of the Week Ending March 29, 2014

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 Garbage Man - Thinking beyond the recycle bin…closed loop recycling.

25+ Digital Wildlife and Nature Maps - Lots of perspectives. I particularly like the Journey North (under Migration and Tracker Maps) because of the time of year….check out robins and monarchs migration.

The 7 Rules of the New Food Revolution - Common sense from Prevention magazine….with links to more information about each one.

Things you should be able to do in your local library - Many communities have library infrastructure originally developed for print media. As more moves toward digital formats - there is opportunity for the library to evolve into something quite different to make the most of the location, building, and engagement capacity. Some of the things on Richard Watson’s list are already part of my library....and others may become the next wave of enhancements.

Google cameras take rafting trip at Grand Canyon - If you can’t make the raft trip through the Grand Canyon physically, take a virtual trip! The Google Colorado River Site is here (there is an ‘Explore the Colorado River’ video toward the bottom of the page that is a short intro to what is available on the site).

What are anonymous companies? An infographic - From TED. “My wish is for us to know who owns and controls companies, so that they can no longer be used anonymously against the public good.” - Charmian Gooch, 2014 TED Prize Winner

Married and working together to solve inequality - Except from an interview with Bill and Melinda Gates

How the Container Store Uses Wearable Tech to Think Outside the Box - Replacing walkie-talkie technology with smaller wearable devices with more functionality.

The $1 Origami Microscope - What a great idea! One of the STEM Fair participants from a few weeks ago lamented that she did not have a microscope easily available for her project. I hope this kind of minimalist design (and low cost) can make microscopes very common around the world - for students (and that virtually everyone is a ‘student’ in some aspect of their life).

Gorgeous Papercut Light Boxes - From two Denver based artists. 

Ten Days of Little Celebrations - March 2014

Over a year ago I posted about finding something to celebrate each day. It’s an easy thing for me to do and the habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations;’ here are my top 10 for March 2014.

STEM Fair - These spring events used to be called ‘Science Fair’ but the fair has enlarged to include Science - Technology - Engineering - and Math so they have changed the name. I have volunteered as a judge for our county fair for the past 10 years or so. It seems like every year is an improvement over previous years and this year there was a bigger improvement than usual! This year the middle school students were much more articulate about the statistics they were using (standard deviation in particular).

Great snowflake pictures - Some years we get snow in March and sometimes we don’t. This year not only did we get a good snow, the situation was ideal of snowflake photography. Of course, I celebrated with snow ice cream!

Raisins soaked in apricot brandy - I plumped some dried out raisins with apricot brandy for an apple - raisin - celery salad. Yummy! I may do this every time I make the salad from now on. Little culinary successes are always worth celebrating.

Volunteer naturalist classes - Last fall had did most of my prep for becoming a volunteer naturalist by shadowing people that had done it before; this spring I am taking the classes and enjoying them tremendously. I even won the drawing for the book give away - Bringing Nature Home by Douglas W. Tallamy. Wahoo!

Philadelphia buildings - I had a hard time choosing between the Philadelphia Flower Show itself and discovering the interesting buildings of downtown Philadelphia which will probably be the focus for my next foray into the city. Either way - the March day trip to Philadelphia was a daylong celebration.

The last two volcano lectures - I worked my way through a series of online lectures on material science related to volcanoes that stretched my memory of chemistry (from classes about 40 years ago) and was thrilled to get to the last two lectures that focused on how lab work is done with silicate glass and how all the research and field work gets translated onto geologic maps.

A clean car - With all the snow, my car became thoroughly encrusted with salt. Its shiny clean look coming out of the car wash was worth celebrating.

Lots of feathers - It was a little disconcerting to find a pile of feathers beside our house but then I realized that the presence of a predator was an indicator of a working ecosystem in our neighborhood….and  I enjoyed having the feathers for a photography project.

Pot luck lunch - I have always liked pot luck events. Sometimes there is a skew to desserts but this one had great variety. If anything, it was skewed toward fancy salads.

Work experiences to pass along - One day I was able to pass along two potential solutions to my daughter from my career: 1) Hotel too expensive for a conference? Room with someone. 2) Logo shirt required for an outreach event way too big to tuck into slacks? Wear it tucked into a skirt or belted like a short dress over leggings or skinny slacks. It’s worth celebrating any time lessons learned long ago are still relevant!

Witch Hazel in Bloom

I enjoyed seeing the colorful witch hazels in bloom at Brookside Gardens recently. I knew that witch hazel was native to North America and was used to make the witch hazel liquid that is so soothing to skin.  Since reading Douglas Tallamy’s book Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, I have decided to landscape with native plants from now on.

So - it was frustrating to discover that the spring blooming trees are hybrids from Japan and China. The native to North America (Hamamelis virginiana) has wonderful foliage in the fall and then blooms in late fall/early winter! The flowers look the same….it’s just the timing of the flowers that is different.

It still might be the smallish tree that I’ll plant next in my backyard, knowing that it will support other natives to make a comeback in my yard.

Philadelphia Flower Show 2014 - Part 3

This third post of photos from our day trip to the Philadelphia Flower Show is dedicated to the sites along the walk between the parking garage and the Convention Center. The Roman Architecture course I am taking via Coursera has sensitized me….I’m noticing more architectural features of buildings. Maybe the theme for my next trip to downtown Philadelphia will be architecture. There are a lot of old and new buildings to see.

One disappointment is how hard it is to see the grandeur of buildings when they are crowded together. It is hard to get a perspective when the whole building cannot be seen without a lot of other clutter. The church on the corner across from the Convention Center is a case in point. The PARK sign looms large in the picture above with the complete steeple!

Then again - the parking garage beside the church allowed me a vantage point to capture some pictures of the church from 7 plus stories up. It’s easy to see some of the weathering of the façade!

Philadelphia Flower Show 2014 - Part 2

This second post with photos from the Philadelphia Flower Show is dedicated to cactus. I like to photograph cactus; there is a starkness about the plants that matches their environment. The various thorn configurations draw my attention too. Now that I have made several trips to Arizona in the past few years and become more familiar with cactus, I discover myself noticing more about them.

The cactus display at the Philadelphia Flower Show was easier to photograph than many of the flower displays. (Now that I think about it - maybe the crowd was not as thick around the cactus exhibit…flowers were a bigger draw). Enjoy the cactus slide show below. I particular like the plant shown at position 8 below --- it looks like a plant that could be right at home in a science fiction novel!

Winter’s Grip Waning? - March 2014

We have had some bitterly cold weather this March. It snowed last week and the temperatures were in the teens. The deer are reduced to eating the old leaves from the pile we made at the edge of the forest. This is a hungry time for the deer.

There was a hawk yesterday at the edge of the forest. I noticed it when it moved and then flew to the branches of a nearby tree. I didn’t actually see it catch anything but later that same day when I ventured out I found a substantial clump of feathers beside our house.

The ground is spongy from the recent thaw and the hyacinth bulbs are just beginning to show. They are at least a week or two behind where they were last year at this time.

As I walked around the house, the tulip poplar still looked very much as it has all winter

But the maple had noticeably enlarged buds. I’ll have to watch carefully to get a series of macro shots as the maple blooms and the leaves unfurl.

Philadelphia Flower Show 2014 - Part 1

We went to the Philadelphia Flower Show last Friday. It was my first time for the event; Philadelphia is about 2 hours up I-95 from where we live so we made it a day trip. My husband bought the tickets and printed a parking coupon via the show’s web site. It opened at 10 and we arrived before 10:30. There were already quite a few people and it got more crowded. Next time I will do the exhibits first and shopping second (just opposite of what I did this first year) although I did enjoy the variety of vendors. I found some great gardening gloves to replace the ones that I threw away at the end of last season.

The flower show was in the Philadelphia Convention Center so it did not matter that it was cold outside. The indoors was full of color that won’t appear outdoors for months! It was a good break from the dull colors of winter.

I’m going to do several posts with photographs from the day trip. This first one is dedicated to flowers. I always like the ikebana arrangements. And the clever use of plants to create insect forms among daffodils was a lot of fun. There were big white paper flowers (with intricate folds and cuts) in one of the Convention Center hallways. Spring bulbs were blooming everywhere! Enjoy the slide show below of flowers from the Philadelphia Flower Show.

Gleanings of the Week Ending March 8, 2014

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.

Over 80s often over-treated for stroke prevention - Sometimes the risks of medications overcome their value as people get older. Are we savvy enough to comprehend the complexity and then make the best decision?

Beautiful Bird Drawings by Brazilian Street Artist L7m - My favorite is the heron (5th one from the top).

Five Native Plants to Add to Your Garden - Spring is close enough to be thinking about gardening so the timing of this article is good if you are still contemplating new plants for this year. I had cardinal flowers last year that bloomed profusely and attracted hummingbirds/butterflies. Hope they come up again this year.

Why dark chocolate is good for your heart - Hurray! I celebrate that the research on dark chocolate is confirming its benefits. It’s one of my favorite little splurges.

Which National Park Drives Are On Your 2014 Calendar? - So many great choices…..

This is what the Internet actually looks like: The undersea cables wiring the Earth - An aspect of infrastructure that we often take for granted because they are so reliable. The vast majority of international traffic is carried by the undersea cables (only a few percent go via satellite).

Incredible Up-Close Textured Details of Frozen Flowers - What a beautiful idea of a macro photography project….but I’m going to wait until summer when I have some flowers from my garden as subjects!

Canary in the Cornfield: Why the Fuss about Monarchs? - I know there are a lot fewer monarch butterflies in my community in recent summers….and less milkweed too. This article explains some background on why that happened.

Sea-level rise threatens UNESCO World Heritage sites - The Statue of Liberty is one. The detailed paper is available here.

Eat Plants and Prosper: For Longevity, Go Easy On the Meat, Study Says - I skewed toward more fruits and veggies - ate less processed grains and meat….and got down to a healthy weight!  

Brookside Conservatory - February 2014

It is so cold outdoors today….I decided to ‘think warm’ by picking my favorite images captured at the Brookside Gardens conservatories a few weeks ago. Conservatories are deliciously warm places to visit in the winter!

On this visit - I did some experimentation with by 8x magnification loupe. All the images in the post include a photo taken with the camera and then one or two images captured with the loupe to add to the magnification.

The fuzz on the petals and imperfections become more obvious.

I’d never seen the variegated croton fruit before. They are almost as colorful as the foliage!

The veins of the hibiscus bud stand out in both magnifications.

Next time, I will make an effort to get magnified views of flower parts!

Just looking at the vibrant colors of these flowers makes me feel warmer!

Gleanings of the Week Ending March 1, 2014

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.

Abdominal fat accumulation prevented by unsaturated fat - Just another indicator that thinking about all kinds of fats as ‘all the same’ is probably not a good idea. The unsaturated fats generally come from plant based foods and fatty fish.

Are bookshelves becoming obsolete? - What do you think? I have started reading a lot more books in electronic form than I do in physically printed form….and I’ve given away all the books I don’t need for reference; the old video tapes are gone too. So I have some empty book cases at this point but I find myself using some of the shelves for other things: the bag of shopping bags and a support for a large garden flag hung from an upper shelf by weighting the flag’s upper edge with unused candle holders. I’m not getting rid of them any time soon because I anticipate moving at some point and needing the storage options they would offer. They are not obsolete….they are just shelves that no longer hold books!

How wolves can alter the course of rivers - TED video about the wolves in Yellowstone National Park. It is an ecosystem story.

The symmetry of citrus is a beautiful thing - I like the colors of the fruit….and then the later collections of eggs, beans, and leaves too.

Where Do People Spend the Most of Their Paycheck on Housing? - (for the US) Find out how your state compares.

Americans Want Antibiotic-Free Chicken, and the Industry Is Listening - Good! But in the meantime - I have switched to organic chicken products because that is the closest to sustainable farming practices (i.e. I want them to go beyond anti-biotic free….I want chicken raised in a way that is not damaging the environment.

Daily Overview - A new picture from above every day! 

Infographic about Personalized Learning - I still not sure I understand how Personalized Learning will work for all students because it seems to depend on all students having the desire for self-directed learning….and I’m not sure that is something that can be assumed. Still - I’m going to follow this series of infographics to learn more about the approach. It is appealing to move away from the factory as the model for schools…but is this best alternative model?

New Water Heater Flies Past Crowdfunding Goal - Something to look into when my old hot water heater needs to be replaced.

'Microbial Pompeii:' 1,000-year-old plaque preserves bacteria, microscopic particles of food on skeleton teeth - I am taking a class on Roman Architecture so this blurb caught my attention - but it wasn’t about Pompeii….it was about a study that looked at dental calculus (plaque) that was dated from about the same time as Pompeii was destroyed by Vesuvius. The plaque provided a window into the diet and microbes of the people living at that time.

People Watching Reflections

One of the pleasures of being out and about is the opportunity to engage in people watching. It’s amazing how quickly we form an impression of someone and make assumptions. There are also embedded learning moments as we see reflections of ourselves in others.

On a recent weekday I made an effort to remember my observations of people as I made a mid-morning errand. Here are the people I saw:

• A woman hurrying as she made a right turn in her car while I was waiting to turn left. She had a cell phone held to her ear. Does anyone handle driving and juggling small electronics well?
• A woman that backed up very quickly from her parking spot. I was glad I had stopped my trek from the parking lot to the store in time. She had not seen me and looked very startled when she noticed I was there; I tried to smile reassuringly. Similar things have happened to me and I always feel discombobulated for some time afterward.
• An older couple walking into the grocery store in comfortable clothes and bulky jackets; they got their basket just before I got mine. Their list must have been as short as mine because they left the store at the same time I did.
• Two produce stockers working at bins of fruit and vegetables talking about when they would be working over the next few days.
• A woman taking inventory in the freezer section. She had her coat on over her employee ‘uniform.’ Grocery stores are often kept on the cool side overall and I can imagine employees that work in some sections need extra layers of clothing to keep warm.
• The monitor for the self-checkout that responded to my glance in her direction within seconds. Eye contact really is quite a powerful social tool.

Traffic was light on the way home and it was so cold that there weren’t any dog walkers in the neighborhood. Somehow I expected to see more people and felt isolated that there were none.

Buds at Brookside Gardens

I took another series of bud pictures when I was at Brookside Gardens last weekend. The photographs were all hand held - no cutting of twigs to make the photography easier! I intentionally looked for trees that I don’t have in the area around my house. I used the 8x loupe; the 22x loupe is too much magnification for ‘hand held’ work.

There was the flower bud of on a red twigged dogwood. They always look like very small Hershey’s Kisses to me.

The gingko bud has a buildup of scales where it is attached to the tree. It will be interesting to watch how the leaf emerges from the bud.

The magnolia leaves were battered by winter but still green. And the leaf bud looked more ready to begin growing rapidly.

The pine is another bud I want to watch expand as spring begins.

Gleanings of the Week Ending February 22, 2014

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.

Aging men: More uplifts, fewer hassles until the age of 65-70 - Interesting that the research is being done but disappointing that it is not terribly insightful yet. It caused me to think about the demographics….men that are in their 80s now don’t have very many 75-years-and-beyond role models in their growing up  because not very men lived that long in prior generations.

10 Things We Learned From Dr. Temple Grandin - Temple Grandin is one of the best sources for insight into autism. I haven’t listened to the webinar recording pointed to in the post yet….it’s on my ‘to do’ list.

Forced Molt: Starving Hens for Profit - Controlling egg production….so that there will be plenty of eggs for consumers all year round. Is starving the hens for 2 weeks the only way?

Colorful Watercolor Paintings of Radiant Trees in Nature - In keeping with Trees being a theme for upcoming photographic projects…..they’re showing up more in my reading and in images I enjoy from others!

6 Offbeat Veggies worth a Try - Maybe some new foods to try….with recipes to get you started.

Sound-sensing cells regenerated in ears of mice with hearing damage - Maybe there is hope to repair time damaged hearing! Since there are a growing number of older people, there are potentially a lot of people that would benefit if this can work in people. Loss of hearing and/or sight are significant hits to quality of life for otherwise healthy seniors.

Time to Sign Up For Summer Field Courses in the National Parks - National Parks are among my favorite vacation destinations. It’s an appealing idea to sign up for a field course!

Involved parents raise slimmer adults - I like the infographic. Glad that the study showed what seems intuitively obvious to me!

Navigate the Global Meat System with New Meat Atlas - The link is to a summary but the 68 page report itself is available by following the link at the beginning of the summary. The report has a lot of graphical representation of data which makes it worth the look.

A lost city reveals the grandeur of medieval African civilization - Still so much history of the world to discover…..

3 Free eBooks - February 2014

It’s time again for the monthly post about eBooks that are freely available on the Internet. The three below are my favorites for February 2014.

Michaux, François André; Hillhouse, Augustus Lucas. The North American Sylva, or A description of the forest trees of the United States, Canada and Nova Scotia. Paris: C. D’Hautel. 1819. Volumes available on the Internet Archive: volume 1, volume 2, volume 3, volume 4, and volume 5. This series fit perfectly with my planning to look at trees more closely this year. Once I found the first one - I went through all 5! They are full of illustrations.

Malonyay, Dezso (Desi). A magyar nép mvészete : számos szakért és mvész közremködésével. Budapest: Franklin-Társulat. 1907. Volumes available on the Internet Archive: volume 1, volume 2, volume 3, volume 4, and volume 5. This series is about Hungarian folk art. I enjoyed the art work rather than trying to wade through the machine translation of the Hungarian text. There is a lot included - ordinary room arrangement with bedding piled high on the single bed, embroidery on clothes (jackets, skirts, shirts, aprons, scares), furniture - painted with stylized botanical motifs, some elaborately carved, decorative facings for doorways and gates, carved or painted canes and knife handles, and dyed eggs with designs created with wax.

Crockett, William Shillinglaw; Smith, William, jr. Abbotsford. London Adam and Charles Black. 1905. Available on the Internet Archive here. This book is about Sir Walter Scott’s country house in the Scottish Borders written at a time when his great-granddaughter had created a ‘catalog’ of Abbotsford. I enjoyed the illustrations more than anything else.

Gleanings of the Week Ending February 16, 2014

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.

Green Schoolyard Movement: Gaining Momentum around the World - Hooray for outdoor spaces that are complex systems….good for the children and the environment!

Aerial 3D Panoramas from around the World - Wow! There is a lot of interesting places to explore on this site. I started with Petra, Jordan.

Fracking in Water-Stressed Zones Increases Risks to Communities – and Energy Producers - Nearly half of the wells hydraulically fractured (indicated by black dots) in the United States are located in areas of high or extremely high water stress…not a good thing. The potential for supply shortfalls poses operational risks to the energy producers as well as risks of rationing and other emergency measures to the wider community.

Special Albinos and Unusually White Animals - Their lack of coloring caused them to stand out.

A Crash Course in Psychology - On YouTube. It will continue on in 10 minutes segments over the next few months. The second installment is here.

Global Health Observatory Map Gallery - There is a pull down list for geographic coverage and topics….and then an area for keywords.   There are lots of maps to explore with this tool. Here is one example: I selected ‘world’ then ‘maternal and reproductive health’ - and there was a list of 3 maps to look at.  One of them was “Maternal mortality ration (per 100,000 live births), 2010.” The US is now as good as most of the developed world in this metric.

The Nine Planets Imagined as One - I like this both as art and science (even if it does include Pluto which is no longer considered a planet)!

The Future of Agriculture (part 1 and part 2) - Fred Kirshenmann talking about going beyond ‘green’ to resilient agriculture. The videos are few years old but I just discovered them (they were suggested as references in the Coursera course I am taking on the US Food System).

Jumping Liquids Mimic Japanese Flower Arrangements - Whether or not they look like Japanese Flower Arrangements….they are worth a look. My favorite is the red, white and purple one need the middle of the series.

The end of the GMO era? -  Some recent stories about GMOs.

There are many parameters for the index and the US does not The full 2013 Human Development report is available here (The Rise of the South: Human Progress in a Diverse World).

Printed Eye Cells Could Help Treat Blindness - The ability to print retinal cells could lead to new therapies for retinal disorders such as macular degeneration....just one of the technologies with potential to improve the quality of life for older people. Not being able to see well produces a cascading effect on mobility and self-confidence that often leads to rapid physical decline.

40 more maps that explain the world - From Max Fisher at the Washington Post. Take your time, enlarge the maps that interest you the most…there is a lot to learn from these 40 maps!

Why 259,969 people taking the same class at the same time might just be the future of education - Co-founder of Coursera, Daphne Koller reminiscing. “We need a way to integrate education much more deeply into the fabric of our lives in a lifelong way,” she says. “And that’s what we’re doing.” And several other recent articles about MOOCs and online education: MOOCs by the numbers: Where are we now?

C40 Cities Releases Landmark Research Revealing Expansion & Acceleration of Climate Actions in Megacities - 98% say climate change presents significant risks to their populations and infrastructure; more than 8,000 climate actions are underway and 41% of those actions are at a transformative, citywide scale. C40 cities in the US are: Austin, Chicago, Houston, Los Angeles, New Orleans, New York, Philadelphia, Portland, San Francisco, Seattle, and Washington DC (details of all cities in the C40 is here) Infographic with a link to the full report included in the article.

A Beautiful Map of Global Ocean Currents - Wow! It’s worth going to the site to look at the visualization in more detail too (click on the globe to enlarge, drag to rotate OR click on the word ‘earth’ in the lower left corner of the image and then experiment with the different projections of the ocean currents at the surface).

Organic Shmorganic - An attempt to sort out the value of organic fruits and veggies for children.

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.

Bomb-Sniffing Rats - An organization in Tanzania trains African giant pouched rats to detect landmines and tuberculosis.  I was more interested in the TB aspect to this story rather than the bomb portion. Once trained, a rat can screen 100 samples of sputum for TB in 20 minutes!

The World as an Apple - A video using an apple to demonstrate how much arable land there is on earth from the American Farmland Trust

Interesting and Overlooked National Parks in America - Some of these have gone on my ‘future vacation’ list.

Fantastic Kaleidosopic Light Paintings Created in Camera - Long exposures and moving lights to create images.

How Parents and The Internet Transformed Clubfoot Treatment - Hurray for the non-surgical solution!

Global Footprint Calculator - If everyone lived the lifestyle of the average American, we would need 5 planets. I did the calculator for the way I live and the answer was 3.9 planets (so I am better than the average American but still pretty far from sustainable).

Setting the Context: A Brief History of EdTech - Infographic (click on the graphic to enlarge or get the graphic in PDF form here and enlarge within the reader) about how technology has evolved in society, business and education from the 1980s to today.

Intimate Portraits of Bees - From National Geographic.

Nature Soundmap - Recordings of natural sounds from around the globe. I listened to several and will come back to listen to more. They have that quality of being gently invigorating and relaxing at the same time.

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.

All of these outbreaks could have been prevented with vaccines - The US has taken a backward step when it comes to outbreaks of diseases like measles and whooping cough. It’s very sad that the downturn has been so abrupt in the past 4-5 years….and that we know why; when will the toll of these diseases reach a tipping point toward increasing mandates for vaccination. All my vaccinations are up to date (and I may ask for a whooping cough booster at my next annual physical since some if my volunteer work is with children).

Wellcome Images - Digital images from the many historical sources made available under Creative Commons licensing by the Wellcome Library, London. All low resolution images are freely available for download for personal, academic teaching or study use. The image at the right is a Mark Catesby illustration of a magnolia blossom and pod.

Top 20 Metropolitan Areas in the U.S.A., 1790-2010 - A very busy chart…but worth look at for a bit. Expand it and take a look. Some cities peaked early (like Baltimore); some didn’t get started until much later (like Dallas and Houston). New York has stayed at the top since it surpassed Philadelphia in the early 1800s.

An earthquake threat is building up in the central U.S. - Lots more people living in the area than there were in the early 1800s (when the last big earthquake occurred there.

Designing Your School of Choice: mySchool - An essay by Adam Renfro about his vision for ‘school.’ There are so many options for future schools….the big challenge will be to choose those options wisely. The balance between needs of the student and society will become more nuanced. It is interesting to observe the uniformity implied by core curriculum, testing, and building structures with the explosion of easily available learning environments that are anything but uniform.

How a Versatile Gut Bacterium Helps Us Get Our Daily Dietary Fiber - Another bit of evidence that our bodies are complex ecosystems with many organisms interacting…..organisms that we need to be healthy!

What's the best place to see or visit in your area? - This is a post where the comments are the main content.  I know in my area I have favorites - and the ones I recommend depend on the interests of the person asking!

To MOOC or Not To MOOC - Infographic. I learned a new acronym: SPOCs is (Small Private Online Courses)

NASA Finds 2013 Sustained Long-Term Climate Warming Trend - The Earth’s temperature has risen about 1.4 degrees F since 1880. The average temperature in 2013 was 1.1 degrees F since the mid-20th century. There is a video showing the temperature changes over the past 6 decades.

Roasted Chickpeas - A recipe I’m going to try this week.

Between the Gaylord and the Potomac

This is my third post about my walk around the Gaylord National Resort & Convention Center week before last (the previous posts were about atrium plants and ice crystals). It was a cold but sunny day when I was there. Aside from the ice crystals - there were some other sights between the glass wall of the atrium and the Potomac River. The white and purple kale had grown lacy like the plants often do mid-way through the winter.

The topiary twists and globes appeared to be weathering the cold as did the neatly trimmed Gaylord logo.

The peeling bark of the birch, the oval shapes of magnolia leaves and the needles of pines added other textures.

Looking out to the river, the Woodrow Wilson Bridge with its drawbridge was in the distance. Ice extended out from the shore.

But the startling event was a gull swopping over the pier to drop a shell (which cracked open)…and then he gull alighting to enjoy breakfast!

Gleanings of the Week Ending January 18, 2014

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.

Over 4,000 Reasons to Love (and Protect) North America’s Native Bees - many agricultural plants are primarily pollinated by native bees (rather than the honey bees that were brought from Europe that are uniquely equipped with the tools and techniques required to do the job. )…and they are declining.

Web Soil Survey - The WSS interface allows you to find out about the soil for a specific area in the US (i.e. an address). It’s provided by the USDA Natural Resource Conservation Service. Reports can be generated about the suitability of the soil for specify uses. For example, I requested a map about the suitability for houses with basements for my neighborhood. Where my houses sits was coded ‘green’….but at one edge of the neighborhood it was ‘yellow’ because the soil changes and there was another small area that was ‘red.’ This would certainly be a resource to check if you were building a house or buying one in an unfamiliar area! The builder can take steps to overcome the soil suitability issues….and avoid wet basements! There is also a site that provides the detailed descriptions of soils here. Did you know that there are 26,000 soil types in the US?
