Gleanings of the Week Ending December 27, 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.

How the Ancient Romans Made Better Concrete Than We Do Now - Article include the ‘how’ plus some information about how the scientists worked out the details. Roman concrete is ‘better’ in terms of durability and its production releases a lot less carbon into the atmosphere.

The Greenland Ice Sheet: Now in HD - The article is a story from Ohio State University. Some of the imagery is available here.

Top 25 Wild Bird Photographs of the Week #74 - As usual - I can’t resist looking through these collections of bird pictures.

The Complete History of Earth in One Tidy Infographic - As usual for infographics…lots of data packed into one page. It is worthwhile to read the text then expand the infographic to take a closer look. I am taking the Origins course so it was a nice coincidence that this graphic came out recently.

Top 10 Public Health Stories of 2014 - We are getting to the end of the year and a number of sites are compiling top stories. This one is about public health.

Over two hundred interesting new species in 2014 - We are still finding a lot of new species in the world - even while we know species are going extinct too. How will we ever know the magnitude of the extinctions when we don’t even know all the species on Earth?

Mosaic Design Gets Assist from Robotics and Enterprise Software - I’ve always enjoyed mosaics and now it appears that robots are being used to create them. Will that make them less expensive (and thus more popular)? I hope we see more mosaics in public places - and in homes too. I’ve noticed several airports with mosaics (one of the newer terminals at DFW and Tucson).

Photography in the National Parks: Looking Back On 2014 - So many good places to take pictures…

2014’s Big Advances in (Biological) Science - A list from The Scientist.

A Video Tour of Yellowstone National Park - A 5 minute video about the geysers of Yellowstone.  It’s a reminder to go back to Yellowstone - soon.

Centennial Park - December 2014

I visited Centennial Park between rain showers yesterday and photographed the Canadian Geese. They were conveniently at the lake shore close to my favorite parking lot.

It is fun to title pictures…give the geese people-like personalities. What do your think of The Orator (below)? The geese in the water look like they are paying attention!

There always appears to be one Guard Goose in the flock.

When one decides to leave - there is often a Follow the Leader exodus.

And what about the strategy of the Big Stretch when they first get out of the water?

Chincoteague Egrets

This is the last post about our weekend trip to Chincoteague back in November. I enjoyed photographing the egrets too much to not include a post about them. They were not as plentiful as the Great Blue Herons or cormorants. The yellow bill and dark legs distinguish the birds as Great Egrets.

It was a very cold day but evidently the fishing was still good. Most of the birds were standing in water - or at the edge of the water - actively looking for their next meal.

Look at those long toes! The angle of the light shows how fluffed the birds feathers are against the cold.

This one has fluffed feathers too - and that primordial looking kink in the neck that egrets and herons share.

Most of the bits they caught were quite small.

This scene with the mallard and two egrets speaks of communication between species - but what exactly are they communicating?

Right after the encounter one of the egrets flew off into the sunset. And that was the end to our egret observations at Chincoteague.

Chincoteague Cormorants

The cormorants were plentiful at Chincoteague when we were there in November.

The first day we saw them in several wet places along the main rode

And then a group on the mudflat just before we reached the beach area. They were preening in the late afternoon sun - unfurling their wings.

One swam way from the group and then flew off low over the water. I like the light on the wings showing the ways the feathers spread as the bird first leaves the water.

The next day we found the birds in the same spots although I didn’t realize it at the top. Doesn’t the post this cormorant is on look the same as the post in the first picture?

Gleanings of the Week Ending November 08, 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.

Americans' view on obesity is changing: Fewer adults see it as a personal problem of bad choices - A survey asked 50,000 US adults and 50,000 healthcare professionals whether they viewed obesity primarily as a personal problem of bad choices, a community problem of bad food and inactivity, or a medical problem. How would you have answered? For myself - I chose to think of it as a personal problem when I got close being obese and have now been back in the normal range for about 1.5 years because of the lifestyle changes I made. However - I am willing to admit that I benefited from a work environment that encouraged increasing physical activity and a nutrition course on Coursera that honed my knowledge of foods. Both of those would be in the ‘community’ realm.

A Wild Ride: 50 Years of the US Wilderness Act - Reflection on the US Wilderness Act by a Fellow at the International League of Conservation Photographers (includes some great pictures)

'Aging well' must be a global priority, experts say - I liked the very last line in this story: “…think about the benefits that an older, healthier, happier, and more productive older population can bring to society as a whole.” An interesting statistic: by 2020, for the first time in history, the number of people aged 60 years and older will outnumber children younger than 5 years.

Why paper is a necessity - From Richard Watson.

A Stunning View of Sunlit Seas on Titan - A montage of images of Saturn’s moon Titan from NASA’s Cassini spacecraft.

Top 25 Wild Bird Photographs of the Week #73 - Which picture do you like the best in this collection? I like the sandhill cranes (toward the end).  I was thrilled to get a picture of some sandhill cranes in Florida (below - Orlando airport's cell phone lot)

What do American babies eat? A lot depends on Mom's socioeconomic background - I was surprised that he study found that some 6-12 month olds were being fed candy, ice cream, sweet drinks and French fries. Are pediatricians and health professionals not stressing dietary needs of babies to new mothers?

A Fascinating Documentary on Crows, One of the World's Smartest Animals - One researcher calls crows “feathered apes”

Climate, emerging diseases - It is difficult to establish a direct link between climate change and evolution of pathogens…mostly because both climate change and pathogens are very complex. But there are emerging or re-emerging diseases being studied that can be statistically linked to environmental changes. 

Incredible New Artifacts Found In 2,000-Year-Old Mexican Tunnel - Even in an area that is well known from an archeological stand point…..there are new finds. This one seems spectacular.  I remember going to Teotihuacan in the mid-1960s and climbing the pyramids. Now there will be even more to see there.

Gleanings of the Week Ending October 4, 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.

Gender barriers: History of discrimination against women in engineering - Much has changed….but there are still challenges to overcome for women in engineering programs (that are cultural rather than intellectual).

Brilliant Idea: The Green Benefits District - New way to facilitate community investment in new tree-lined streets, parks, and gardens.

The Most Important Animals You May Never Notice - Mussels!

Critically ill ICU patients lose almost all of their gut microbes and the ones left aren't good - Another reason to minimize excessive use of antibiotics….and better understand gut microbes.

Whipsnade Zoo Has A Baby Elephant With The Tiniest Little Trunk - A short video.

Stain Solutions - From the University of Illinois Extension

Foodie Bees: Insects Head Downtown for Dinner - There are many kinds of bees…they are versatile…and gardens everywhere can become better habitats for them!

Immune system of newborn babies stronger than previously thought - Hurray! Newborn immune systems are different….but they work effectively in many instances.

Enjoy the Fall Migration: Your Guide to Bird Observatories - Thinking about birds in the fall…maybe something to combine with a fall foliage trek over a long weekend.

Sweet Potato Chocolate Chip Cake - The cake may not need any icing at all. I am going to harvest my sweet potatoes this weekend….so I am looking for something special to make with my small crop!

Belmont

I’ve participated in several programs at the Belmont Manor and Historic Park as a Howard County Conservancy Volunteer over the past month. September is a good month to see maturing seeds - in the trees: Maple

Dogwood

And sweet gum.

There are other plants going to seed: grasses

And fluffy seed pods in the meadows.

The flowers are mostly done for the year although I did photograph a chicory that was growing at the edge of mowed path.

But it is the very air of the place - looking up to into an old sycamore,

The top branches of other trees,

And starlings swirling - that is the most special.

Belmont is a place with a long history and one looks out from the mansion that is somehow not as important as the vista.

Gleanings of the Week Ending September 20, 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.

Comprehensive recommendations on care of women at menopause, beyond - From The North American Menopause Society (NAMS). The recommendations are available on the web here; it is well organized and in clear language. What a good reference!

What to Do in Shenandoah National Park Now: Take a Hike into the Landscape - Maybe we should take a day trip!  Shenandoah is the closest national park to where we live in Maryland.

Some great statistics - From Richard Watson…about some worldwide trends - presented as an infographic.

Fracking: Gas leaks from faulty wells linked to contamination in some groundwater - Highlighting the need to improve well integrity, the study showed that where contamination has occurred it was caused by poor casing and cementing in the wells.  Does that mean that the company responsible for the casing and cementing is liable for damages?

NASA Mars spacecraft ready for Sept. 21 orbit insertion - We were in Florida last fall for the MAVEN spacecraft launch…and now is about to enter into Martian orbit!

Top 25 Wild Bird Photographs of the Week #72 - I always enjoy the wild bird photograph posts from The Wild Bird Trust. In other bird-related news - there is new research just published: Bird Diversity Drops from Forests to Farms.

U.N. Predicts New Global Population Boom - The human population on Earth could hit 12 billon by 2100 (not taking into account the effects of climate change, food shortages, disease or conflict). Previously it had been widely assumed that the population would flatten around 2050.

How salt causes buildings to crumble - There are so many ways!

Tree rings used to determine history of geological features, arroyos - This blurb caught my eye because of a recent volunteer naturalist training about using tree rings for looking at climate change from 1400 to now. This is a detailed study of the arroyos in northern New Mexico using burial dates in tree rings of salt cedar and willow.

Jaime Lerner’s Urban Acupuncture - A thought provoking book review. What makes good urban life? 24 hour groceries and delicatessens? Open air markets? Music? What kind of parks, plazas, and square work best? The book is available from Amazon.

3 Free eBooks - August 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 August 2014.

Shelley, George Ernest; Keulemans, John Gerrard (lithographer/llustrator). A monograph of the Nectariniidae, or, Family of sun-birds. London: Published by the author. 1876. Available from the Internet Archive here. The illustrations are the best of this book and there are other books that have the same lithographer also available on the Internet Archive that are worth a look too (although I think the sun-birds book is the best).

Dam, Jan Daniël van; Tichelaar, Pieter Jan; Schaap, Ella; Lins, P. Andrew. Dutch Tiles in the Philadelphia Museum of Art. Philadelphia: Philadelphia Museum of Art.1984. Available from the Internet Archive here. I started looking for books that had tile patterns after the Coursera course I am taking on Symmetry used them as part of the introduction to the vocabulary used to discuss symmetry. What do you think of the grapes and pomegranates tiles? Notice that the tiles are rotated to create the pattern (the stems always point to the center).

an hui sheng chu si hai zong zhi hui bu. xiao mie wen ying de ye sheng zhi wu. 1958. Available from the Internet here. This is a Chinese botany book. I always enjoy botanical prints and these were no exception. It was also good to realize that books from around the world are making their way into the archive.

Enjoy these and many other books that are freely available on the internet.

Egret in Flight

The great white egret that makes its home at Josey Ranch Lake in Carrollton Texas is very photogenic. I already included a picture of the bird in my post for August 3.  A few days later, the walk around the lake provided ample opportunity for egret photography experiments.

The classic picture of an egret in search of a meal was almost too easy.

The water was not quite still enough to get a perfect reflection….but I tried the shot anyway.

I got a little too close and the bird took off. I managed to take 4 pictures as it flew across the lake. This one is the best focused.  

The clip of another picture shows the flexing of the feathers at the end of the wing; the rest of the photo is unfocused or over exposed.

Walking at Josey Ranch Lake

Generally walking in Texas is a morning activity - before the hottest part of the day. The lake near the library in Carrollton TX is a popular and easy hike. The birds are accustomed to the walkers so it is a great place for photography. There were a few pigeons; it seems like almost all city parks has pigeons.

There was a Little Blue Heron that I saw both days I walked the loop. It appears to be a bird that likes to fish in isolation.

The great white egret likes to company of the ducks. Both days the bird was surveying the lake from about the same place and with the same company.

There was a pair of swans in the same group.

A juvenile swan was also nearby. Another walker commented that there had been 4 ‘ugly ducklings’ but this was the only one from this year’s nest to survive (the turtles in the lake are the probably predator for the very young swans). The one that is left is clearly large enough now to be in no danger from turtles. The juvenile will stay with the parents until the feathers are all white later in the summer.

In another pond we had seen two swans the first day. On the second day we saw only one and there were a lot of feathers on the duck-weed coated pond. We were relieved when we saw the second swan - obviously a little ruffled from a round with some predator (maybe a dog?).

There were several nutrias around the lake - an invasive rodent that most states are trying to eradicate. We saw three but another walker said there were probably 8 or 9 round the lake. They seemed to be as acclimated to people being around as the birds. I wondered why they had not been trapped and taken away.

Gleanings of the Week Ending July 5, 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.

How Did This Ancient Civilization Avoid War for 2,000 Years? - This article linked well to the Paradoxes of War course I am taking right now….one of those little serendipities of life. There are hints of other cultural norms that were so different from our own that we can’t quite fathom how they worked.

Oklahoma earthquakes induced by wastewater injection by disposal wells, study finds - I saw a story about the Oklahoma earthquakes on the evening news that featured a home owner from Prague, OK whose house had been badly damaged. I have a family connection to the area: my great-grandparents farmed in the area and my one of my grandmother’s first memories was of their house blowing away. They worried about tornadoes rather than earthquakes. I’m glad there are studies being done to understand why the dramatic increase in earthquakes is happening….and help us make better decisions about wastewater disposal.  On the positive side for Oklahoma, at least they had data available that could be used to determine the problem. Now the question is - what action will result? And what about China’s Dirty Pollution Secret: The Boom Poisoned Its Soil and Crops? Both of these instances seem to be cases where the price of ‘development’ is becoming unexpectedly high - and maybe it is going to get higher over time.

Chemist with Visual Flair Answers Burning Food Science Questions - A high school chemistry teach in the UK has a flare for chemistry info graphics. The ones collected in the NPR post are about food but he has others at his open web site: Compound Interest.

Top 25 Wild Bird Photographs of the Week #69 - I have to include one of these periodically. Which is your favorite? Two near the end are mine: the egret and peacock (and I can't resist including one on my own peacock pictures with this post).

Why Online School? Why Full Time? - A survey to find out why parents and student use online schools full time. The two reasons are “want a change from their local school” and “require or want greater flexibility.”  The survey was of parents of students of Connections Academy, an online school.

Slow media - Sometimes the alternative to ‘fast’ is what we need!

Ancient baby boom holds a lesson in over-population - A case study from the American southwest: farming and food storage resulting in high birth rate until there was a drought which caused the crash.

4 New Energy Maps Show A Lot about Renewables - Wind, solar, biomass and geothermal…the US has a lot of potential.

New study from population and development review finds flaws in mortality projections - There is good news and bad news: The good news is that the decline in cigarette smoking will almost certainly result in longer-living older populations. The bad news is that current public policy around the world has not included that change in mortality projections (i.e. governments are underestimating the number of older people for the next decades…and were already struggling with the shifting demographics).

50 States, 50 Spots Natural Wonders - From CNN. There are a lot of natural wonders is virtually every state I’ve visited….too hard to pick just one…but fun to think about.

3 Free eBooks - June 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 June 2014.

Birds, Illustrated by color photography. Chicago: Nature Publishing Company. 1897. Fourteen volumes are available from Project Gutenberg here. The image of the kingfisher is from volume 1, no. 2.  I am slowly working my way through all the volumes. I’ve enjoyed the first 4 so far.

Cailliaud, Frederic. Voyage a Meroe. Paris: L’Imprimerie Royale. 1826. Two atlas volumes are available from the Internet Archive: volume 1 and volume 2. I just finished a Coursera course on The Art and Archeology…and was thrilled to find these books online. They have drawings of some things that have been degraded between 1826 and not - either through simple ravages of time or rising water from dams built on the Nile.

Versailles et les Trianons : vues photographiques. Versailles: Moreau. 1880. Available from the Internet Archive here. It’s been a draw for tourists for a long time….and people bought souvenirs in the 1880s like this book!

Gleanings of the Week Ending May 10, 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.

Dynamic Paintings of Birds Capture the Essence of Flight - Appealing work.  I usually like photographs of birds in flight better than paintings….but these are an exception.

The Coming Antibiotic Crisis, Revealed in Maps - Will we eventually revert to infections that kill like in pre-antibiotic days?

Inside Turkey’s Top Archaeological Sites - From the Dialogue of Civilizations: Gobekli Tepe (oldest human-constructed ceremonial site in the world) and Zeugma (mosaics). Links are included to photos, galleries and virtual tours of the sites. There is also a link at the bottom of the article to other posts about the Dialogue of Civilizations.

10 Spring Cleaning to Dos for Your Digital Abode: Part II - I posted the Part I of this list a few weeks ago I my cleanings list.

Basic science finds corporate refuge - With funding from the US government declining, corporations are picking up some of the funding shortfall.

A History of Garbage in Space - In just over half a century, we’ve created 17000 objects in earth orbit. The majority of them are ‘fragmentation debris.’

What's Your Major? 4 Decades of College Degrees, In 1 Graph - This is a graphic to looks at - move the cursor over it to get numbers that correspond to the colors. Click on the one and a graph with just that major will appear. Physics is almost non-existent in the graph (higher in 1970 than now).

Watch Stunning First Simulation of Universe’s 13-Billion-Year Evolution - In a little over 4 minutes, a simulation of the universe from the beginning to now.

Ocean acidity is dissolving shells of tiny snails off U.S. West Coast - Scientists has previously thought it would be decades before this result of ocean acidification would be observed. It appears that this is one consequence of climate change that is happening faster than anticipated.

Neuroaesthetics - A relatively new field that studies the way humans process beauty and art.

Dallas Arboretum - March 2014

Late March is probably one of the most beautiful times of year to walk around the Dallas Arboretum. We went on a week day so it was overly crowded. It was sunny and cool - comfortable with a light jacket. I took so many pictures it has taken be a month to pick my favorites to include in the slide show below. The Dallas spring was almost a month ahead of our spring in Maryland this year!  Enjoy this celebration of springtime!

Robins!

Robins on the lawn or in the garden are another sign of spring. The ones I’ve seen recently appear to be tolerating the last blast of winter quite well. Even without their feathers fluffed they look well fed! The robins pictured in this post seemed almos tame....alowing me to walk relatively close (and then use the camera's zooom) to get their pictures.

We always seem to have the most robins in the spring. They seem to move around in small flocks and then we see them one at a time or in pairs later in the season. Perhaps some of them head further north and a few stick around to nest in our area. Almost every summer we have a nest under our deck.

3 Free eBooks - March 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 March 2014: birds, insects and flowers. I am anticipating spring!

Gould, John. The Birds of Europe. London: R. and J.E. Taylor. 1837. Five volumes are available on the Internet Archive: volume 1, volume 2, volume 3, volume 4, and volume 5. A few years ago I saw an exhibit of John Gould’s bird prints (large books) in a museum in Tennessee….and made a note to check the Internet Archive for any scanned versions of his work since the exhibit only displayed a small portion of the volumes. It was such a pleasure to finally browsing through these books online.

Fabre, Jean-Henri; Stawell, Rodolph, Mrs; Teixeira de Mattos, Alexander; Detmold, Edward Julius. Fabre's Book of Insects. New York: Dodd, Mead and Company. 1926. Available on the Internet Archive here. The illustrations by Detmold are the draw for this book.

Galeotti, Henri); Funck, Nicolas; Morren, Edouard. L'Horticulteur practicien; revue de l'horticulture franaise et trangre. Paris: A. Goin. 1858. Two volumes are available on the Internet Archive: 1857 and 1858. The illustrations of rich with color and detail of flowers….it’s like touring a conservatory online. I picked the forsythia illustration because it reminded me of how disappointed I that our neighbor’s forsythia is likely to have a hard time this year since the deer have eaten all the tender parts. It might not manage any blooms at all!

Macro Feathers

The pile of feathers beside the house last week prompted a little photography project with the 8x and 22x loupes. I found myself concentrating on the ends of the feathers….and how different the wing feathers were from the fluffy down.

Gleanings of the Week Ending March 15, 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.

10,000 years on the Bering Land Bridge: Ancestors of Native Americans paused en route from Asia - I’d always assumed that the ‘land bridge’ was narrower - just across the narrowest part of the Bering Strait.

Top 25 Wild Bird Photographs of the Week #63 - I haven’t included one of these in my gleanings recently….doesn’t mean that I don’t continue to enjoy them. My favorite in this batch is the kingfisher with the little crab in its bill.

Is Daylight Savings Energy Efficient? No, Says Expert - Every spring and fall I hate the time change. Does anyone like it? Sometimes I think governments like the idea simply because it confirms that they have the influence to cause the population to do something in synchrony!

Nutrition Facts Label: Proposed Changes Aim to Better Inform Food Choices - The new labels are in a 90 day comment period from the FDA. What do you think? I like them. The revised labels include new info (added sugars, Vitamin D, and potassium) that I have missed in the past. I like the larger calorie count and the attempt to make the serving size the size of a real serving.

The Weight of Mountains - A short film (11.5 minutes) about how mountains are made….live…and die.

Mothers leave work because they don't want to behave like working men, study suggests - ‘Presenteeism’ (the notion that being at your desk until late is required, even if there is nothing to do) should not be a requirement for men or women….but it has the effect of driving women out of the workforce more often than men. What a waste of skills and education! Will the workplace change over time?

Deer proliferation disrupts a forest's natural growth - This study was done in Ithaca NY but Maryland has very similar problems. The deer are so prolific that they are eating all their preferred foods down to the ground.

NASA's Breathtaking Images of Space - The view from space….always awesome.

Women's jobs are poorer paid, less flexible, more stressful - My career was in a male-dominated field and was well paid. About 20 years in, I realized that while I did work longer hours overall than women in many other fields, the stress was generally positive and not brutal in duration….and the flexibility increased over the course of my career too! So - this research result meshes quite well with my experience from the mid-70s onward.

Honeybees reveal that evolution is stranger than you ever realized - Just how do sterile bees contribute to the fitness of their species? Kin selection. That’s why honey bees in Yemen have adapted to be excellent at air conditioning their hives in the hot desert air and Japanese have adapted to combat deadly wasps in a unique way.

Ten Days of Little Celebrations - February 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 February 2014. I’ve grouped my little celebration into 4 groups this month: weather, food, family, and loupe photography.

Weather

A warm day - In February - the occasional warm day is indeed something to celebrate!

Snow and more snow - I like snow days too, particularly when I don’t have to leave the house. I enjoyed hot tea with milk….and worked out a plan to photograph snowflakes. I didn’t even mind a certain amount of shoveling of snow!

Birds - The changes in weather result in more birds be out and about when the weather is a little improved. We’ve seen juncos, cardinals, robins, chickadees and heard the crows!

Food

Graham Cracker Crumb Cake - Someone made a graham cracker crumb cake as part of the refreshments for a lecture I attended….and I liked it so well I looked for a recipe via the Internet…and made one myself. Yummy! I have always liked graham crackers and this is just one other form to enjoy.

Edamame - What a great way to increase the protein in salads! My grocery store had them already shelled!

Family

Phone calls - I celebrate the ease we can keep in touch with family that lives far away. It is not as good as living in close proximity…..but it enables us to sustain relationships until we can be together again.

Anticipating visits - There are two opportunities to see far flung family members - in March and May - that I am already anticipating…and celebrating.

Loupe photography

Snowflakes - I was surprised at how effective the loupe magnification is for snowflake photography. It is quite an adventure to discover for myself how unique and beautiful they are.

Buds - Buds are going to be a longer term fascination as they unfurl into leaves and flowers. I celebrated that I thought of the project early enough to get the bud before the unfurling!

Broccoli - I knew it was good to eat but the loupe gave me more reason to celebrate broccoli’s form and color.
