Gleanings of the Week Ending September 12, 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.

Gene leads to nearsightedness when kids read - The incidence of myopia is increasing around the world. In the US 44% of adults are nearsighted, up from 25% 30 years ago. And in some parts of Asia, 80% of young adults are now myopic. There is a lot of research re cause and possible preventions. This is just one.

The lost tunnels buried deep beneath the UK - There are tunnels below Liverpool! They are 200 years old and filled in when people complained of the smell (as they were used as underground landfills. Now they are being excavated.

Midday naps associated with reduced blood pressure and fewer medications - Yet another reason that midday naps are not a bad thing.

Standing on their own four feet: Why cats are more independent than dogs - We are a cat household…ours certainly have an independent nature! This research points out that ‘cats are much more autonomous when it comes to coping with unusual situations.’

Biodiversity belowground is just as important as aboveground - We know that the biodiversity above ground is in peril in much of the world…but the belowground organisms are not as well known or studied.

Intense Aurora Display over Sweden - I don’t live far enough north to see aurora….so videos like this are an opportunity to see the phenomenon and marvel at how finely tuned our planet is.

Check Out Life Spans around the World — and Likely Years of Ill Health - I like the idea of looking at life expectancy and unhealthy years together rather than life expectancy along.

Stunning Macro Photos of Delicate Butterfly Wings Look like Shimmering Petals - I tied to do some macro shots of a butterfly wing (best image is to the left)…frustrating experience. This post motivates me to try again and get rid of the pesky bubbles!

Recovery: Rare Turtle Gets a Second Chance - It’s always good to hear a story about recovery rather than extinction….but we have to do something about people releasing non-native red-eared sliders and hurting the indigenous native turtles.

3-D Printing Breaks the Glass Barrier - I watched the full video from the MIT Media Lab; it’s only about 4.5 minutes. I like glass!  

Gleanings of the Week Ending August 22, 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.

Why statins should be viewed as a double-edged sword - The results of a study from Tulane that indicates that statins may not be appropriate as a preventative measure for those who do not have cardiovascular disease…because statins increased aging and death of mesenchymal stem cells (MSCs); MSCs can become all types of cell types including bone, cartilage, muscle cells and macrophages. Thus - the risk/benefit for people without cardiovascular diseases need careful consideration.

Four Ferns for Dry Places - I planted some Christmas fern under my deck and it is thriving!

Smart Windows Just Got Cooler - I’ve always thought it would be great to have windows that could selectively block light - and it seems like there is ongoing work. This start up is based on chemical engineering work from the University of Texas at Austin. It would be great to not need to close the draperies in my west-facing office on hot summer afternoons!

Survey reveals best practices that lead to high patient ratings of hospital care - It turns out that it is not about high-tech resources!

Butterflies in Peril - Droughts and habitat fragmentation….hard on butterflies. Many are becoming locally extinct. We are not in a drought here in Maryland but we are very away of the decline in Monarch butterflies in our area.

The Next Great GMO Debate - Evidently Monsanto is learning how to modify crops by spraying them with RNA rather than tinkering with their genes. What about unintended consequences? I’d rather we focus research on sustainable agricultural practices rather than new sprays that may have a short term benefit and potentially have a long term consequence.

An inside look at the world’s biggest space telescope - An update on the progress on the James Webb Telescope (video and pictures).

Cherokee Purple: The Story behind One of Our Favorite Tomatoes - These are the type of heirloom tomatoes we’ve been getting from our CSA; they are tasty. I enjoyed hearing about the history of how it became one the favorite heirloom tomatoes

The Periodic Table’s Endangered Elements - There are 9 elements that may ‘run out’ on Earth within the next 100 years and 7 additional ones that may join the list because of increased use.

Field recording Irish traditional music - Instrumental, song and dance videos…the roots of Riverdance.

Brookside Gardens Wings of Fancy - August 2015

We made a second trek to the see the butterfly exhibit at the Brookside Gardens conservatory - a great outing for a guest in town for the weekend.

Often the contrasting colors of the flowers and the butterflies prompts me to take a picture.

Sometimes a tree trunk seems to be a favorite resting place for butterflies. One had at least 6 on it as I walked by.

I wondered how this morpho was still flying. Parts of both wings are missing.

There were several that hung gracefully upside down on their flowers.

Others fluttered to keep their place or move slightly to the next flower. Sometimes the slightly different motion of the two parts of the wing can be detected.

Some butterflies are more colorful on the underside.

When butterflies perch close to each other - resting - I often wonder if they are aware of each other.

Last but not least….I am always on the lookout for Monarchs. I wish we had them in our neighborhood like we did 20 years ago…but now I seem them most often in exhibits like this one.

Brookside Gardens Walk

When we went to Brookside Gardens last weekend, the parking lot at the conservatory was already full just after 9 AM…so we parked in the Nature Center lot. I will be glad when the main lot is finished but the estimate now is late fall or even into winter. We walked over the boardwalk that traverses the woodland and stream between the Nature Center and Conservatory.

Hibiscuses are blooming where the boardwalk joins the Brookside path.

Instead  of turning toward the Conservatory - we walked toward the Tea House with woodlands on the left

And the renovated ponds on the right. A dove was getting a drink from the rocks where the overflow water from the ponds runs off.

We walked to the far end of the gardens and out the gate toward the larger pond in Wheaton Park in search of dragonflies. We saw the insects but they were not sitting on anything long enough for photography. I liked the islands of vegetation in the pond…and their reflections.

Occasionally there were leaves already changing color. It’s a little early for that but it is not uncommon to see colors like this pop out of the greenery.

Back in Brookside Gardens we saw a toad crossing the path

And pink lilies like my parents have in their garden in Texas. These are near the visitor center and there were more in the woods seen from the path between the visitor center and conservatory.

The Wings of Fancy exhibit is inside the conservatory but there were a lot of active butterflies in the gardens. This tiger swallowtail is reaching way down into a petunia.

Some flowers were very popular. Even the mothers that often look rather drab - are photogenic with a pink, yellow, and green background.

The most butterflies I got in a single picture was three!

Brookside Gardens Wings of Fancy - July 2015

Brookside Gardens has a live butterfly and caterpillar exhibit in their conservatory running from July 1 to October 25. We tried to go last Saturday but it was too crowded; parking is very limited because of ongoing construction of the lot associated with the visitor’s center. Sunday was better; we arrived at 9:30 AM when there was still plenty of parking and took a look at the outdoor gardens before the exhibit opened at 10.

The exhibit was warm and humid - wonderful for butterflies and only a little uncomfortable for humans. I was glad the space was not overly crowded. My husband and I managed 45 minutes in the sauna like conditions!

There were lots of butterflies to photograph and we made several rounds spotting butterflies that were feeding or resting at every turn. I challenged myself to try capturing butterflies in different poses than the usual wings-spread/from-the-top view.

The patterning on the underside and the intricacy of the head parts show up better in many of these views.

Sometimes a bit of structural color shows up that wasn’t noticeable before…like the bit of blue along the lower edge of the wings (below).

Sometimes it is not clear how they are balanced on the plant…and I’m always surprised when they look ‘hairy.’

I was trying to capture butterflies but noticed that this plant looks a lot like a fiber optic light! The butterfly seems so precariously perched but it was stable enough feed on the flower.

Many of the butterflies looked battered but could still fly effectively and continue to feed.

The one with the pale green area and darker green iridescence might be my favorite for this year.

The large morph butterflies are difficult to catch with their wings open. This one feeding on watermelon had lost part of one wing so the blue color of the other wing was revealed. I saw several with wings like this - and they were still flying!

A clear winged butterfly sat on an elephant ear leaf…and sipped at a water droplet.

Monticello - June 2015

I’ve made periodic trips to Monticello since 1983 when I moved to the east coast from Texas. There always seems to be something new to learn at Thomas Jefferson’s home. We arrived early for the first Behind the Scenes House Tour and Day Pass - with reservations made ahead of time. There was a lotus blooming in the courtyard of the visitor center; I had not even remembered a pool there from my previous visit so it was a pleasant surprise.

Later in the day it would have been impossible to get pictures of the house without people milling around. Did you know that Monticello has three floors above the basement? Jefferson intended for it to look like a single story. Here’s how he got light to the 3 floors. Look at the stacked windows on the front of the house. The windows with the shutters are the first floor. The windows with a white frame and no shutters are the second floor. They fill the lower half of the second floor walls. The third floor has sloped ceilings and skylights!

The viewshed for Monticello is somewhat changed from Jefferson’s day. There were farms where the trees had been cleared within the viewshed during his time but probably not as many clusters of other buildings. From the house it is easy to position yourself where trees block the view.

No pictures are allowed inside the house so I don’t have a picture of the staples that were used to support the alcove beds. I’d not noticed how the beds were supported on previous visits. Jefferson’s bed was open on both sides (and he had a clock positioned on the wall at his feet…he got up when it was light enough for him to see the clock). The other alcove beds had walls on three sides; Dolly Madison visited with her husband frequently and did not like them (probably because she was on the side to the wall!).

The kitchen has separate ‘burners’ for cooking at different temperatures. But they are not vented. The kitchen would have been hot, sooty, and smoky.

The back of Monticello includes the dome. More of the house is visible these days because a giant tulip poplar planted by Jefferson had to be cut down in the 1990s. The inside of the dome room is being monitored closely these days because there are cracks that appeared in the plaster after an earthquake…and they are getting larger.

After Jefferson’s presidency there were quite a few people living at Monticello: his daughter and her many children and his sister….as well as other relatives and friends. They had to have quite a garden to feed everyone.

The view from Mulberry Row - the series of cabins for the slaves that worked in or near the house - may have included more trees that it does now. The kitchen is to the right of this view…the south pavilion above on the far left.

My favorite photograph of the house during this visit was through the flowers.

I was surprised at the number of butterflies we saw in the short walk around the grounds.

Instead of riding the bus down the hill to the visitor center we walked past the cemetary and through the forest.

And then it was time to splurge for lunch at Michie Tavern. The food is good….but I’m not as fond of ‘all you can eat’ places as I once was. In this case - it is tradition. I think we have gone to Michie Tavern for lunch every time I’ve visited Monticello!

3 Free eBooks - April 2015

It seemed harder than usual to pick my favorite 3 eBooks to highlight this month. The visuals in all of these are spectacular.

Tuck, Steven L. A History of Roman Art. Wiley Blackwell. 2015. Available on the Internet Archive here. I enjoyed this book - many of the pictures taken by the author - as a follow on to the Coursera course on Roman Architecture last year.

American Paradise: The World of the Hudson River School. The Metropolitan Museum of Art: New York. 1987. I remembered a type to the Catskills several years ago….and several of the places depicted by these artists. I realize now that I learned a lot about composition of landscape photographs from the Hudson River School artists.

Godman, Frederick Ducane; Salvin, Osbert. Insecta. 1901. I enjoyed the electronic version of the Biologia Centrali-Americana made available in the Smithsonian. The digitization project it not complete but I looked particularly at the Lepidoptera (butterflies) volumes (Rhopalocera and Heterocera) and enjoyed the color and variety of butterflies as of 1901. How many of them still exist. There has been a lot of habitat change in the past 114 years.

Butterfly House at the Texas Discovery Gardens

The Butterfly House at the Texas Discovery Gardens is a colorful place to visit in the winter. I was there earlier this month when I travelled to Dallas. There are lush tropical plants and butterflies! It was not crowded even though it was a weekend.

The Butterfly House is a multistory conservatory with a ramp that wonders through the tops of taller foliage down to a courtyard with water features. The butterflies were on all levels but densest near the water.

The enclosed space was bigger than the Tucson Botanical Garden butterfly exhibit but there were not as many butterflies when we were there and not as many people either.

The standout memory of the day was color - since so much of Texas (and Maryland) is mostly drab in winter. The flowers and fronds were a welcome change from winter overall.

We stayed for the daily release of newly hatched butterflies at noon. They were brought out in a net barrel. The tiger swallowtail did not want to leave the safety of the container. Maybe its wings were not entirely dry.

Some of the new arrivals left the container quickly but chose to walk rather than fly!

Children gathered around to see the release and noticed a more battered butterfly nearby on the ground. They tried to entice it to safety (out of the walkway).

Butterflies and conservatories….always a pleasant interlude.

Tucson Butterflies

It was warm enough for butterflies to be active on the lantana on the University of Arizona campus week before the last but the bigger butterfly treat was at the Tucson Botanical Garden’s Butterfly and Orchid Pavilion.

The pavilion is a warm, misty place where the butterflies are numerous enough to get some good photographs - after the camera acclimates to the steamy environment. The exhibit gets new additions each day a pupae in the building next door hatch and are brought into the pavilion. We saw a glass wing being released and then a very large moth - a cecropia. I included two pictures of it in the slideshow below.

The butterflies only live about 2 weeks. Some of them don’t eat in their adult phase - others are active on nectar plants. Caterpillars and their food plants are not part of the exhibit (all the pupae come from the native countries for the butterflies).

What a delight of warmth and color in January!
