Gleanings of the Week Ending January 28, 2017

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.

Danish Study Raises More Questions about Mammograms’ Message – Evidently doctors can’t yet tell which tumors really need to be treated and which might be able to just monitor. There is a tendency to think that breast cancer screen is better than actually is….and that leads to a lot of potential unneeded (and traumatic) treatment.

Watch Geologic Machinations in Motion at Hawai’i Volcanoes National Park – About a year ago, I visited the Hawai’i Volcanoes National Park so I am always looking at items with news from the place. I don’t know that I would be up for an 8-mile hike to see the new viewing area.

An Iceberg Larger than Rhode Island is Poised to Break from Antarctica – When it goes – the Larsen C Ice Shelf will lose more than 10% of its area….and the maps of Antarctica will need revision.

Stunning photos of trains roaring through picturesque landscapes – Eye candy for the week.

Recovery: Saving the Lake Erie Watersnake, a lesson in outreach – Not poisonous but ill-tempered and smelly. Only found in the lake’s western basin on islands…French explorers found them sunning themselves in heaps, knots and snarls. It turns out that people killing the snakes was a bigger factor the reduction of numbers than habitat loss….and thus an education campaign is helping increase their numbers!

The Chemistry of Popcorn -  Probably my favorite snack. We have a special bowl that allows us to pop it in the microwave (no weird chemicals like in the bags of microwave popcorn).

Why America is Growing the Most Sweet Potatoes since WWII – I’ve always liked sweet potatoes….and it seems that more people do these days since it has become a popular crop for former tobacco farmers and over 11% of the crop is exported!

Arctic melt ponds form when meltwater clogs ice pores – In the field (of ice) and an experiment to discover how melt ponds forms on porous ice.

Ten more field guides and references for the serious naturalist – I think I might buy the one about bees.

Obesity is barely covered in medical students’ licensing exam – Not good since nearly 40% of adults and 20% of children and adolescents are obese in the US.

Centennial Park – January 2017

Late last week there was a sunny day…and I accompanied my husband to Centennial Park. He walked all the way around…I was busy taking pictures! The first subject was a red tailed hawk high in a tulip poplar tree. The angle wasn’t great – but the reddish tail feathers were a little visible in one of the pictures and the fluffing of the breast feathers was a good clue to how cold the day was.

There were Canadian Geese of course. They are always at Centennial. I experimented with different angles…reflections, near silhouettes, the awkwardness of the bird on land.

There were two types of diving ducks. Both are winter birds in Maryland. They are a challenge to photograph because the go completely under the water then pop back to the top for few seconds. The Buffleheads were on the other side of the lake from where I was…but the white on their heads make them easy to identify even in a blurred picture. The one on the left is a male; the right is a female….not enough of a side view to tell the one in the middle.

The other diving ducks on the lake were female ruddy ducks. Their tails are a stiff fan. I didn’t see any flipped upward but these ducks were actively feeding…only staying on top of the water for short periods of time.

I decided it was a little chilly to stay out longer so headed back to the car. Along the way, I tried a ‘looking up’ shot of small cones. I like the sharpness of the lines within the cones – light and shadow.

There is always something to photograph at Centennial Park!

Zooming – January 2017

I use the zoom on my camera in so many situations – to look at the details of a façade in McKinney, Texas,

A swan and coot at Josey Ranch.

And then there is the combined strategy of photographing through a window and zooming: crepe myrtle seed pods through the window of the hotel in Grapevine, TX (when it was very cold outside),

Kitt Peak (probably) taken through the window of the plane taking off from Tucson headed to Los Angles, and

A tangle of plum tree branches covered in water droplets in the morning sunshine.

Sometimes the zoom is so great that it makes the picture look more like a painting. I thought this shelf fungus looked like a stylized bird!

Hiking at Belmont

I took a winter hike at Belmont yesterday. The trek went from the Carriage House at Belmont onto the Patapsco Valley State Park’s Ridge Trail – making a big loop. It was a lot of up and down hiking through the winter forest. I had limited time to take pictures….it was a hike not a photo shoot. I liked the very green moss on this fallen tree – that has been cut up after it fell across the trail.

Sometimes the white of shelf fungus catches attention too.

This log had a mixture of shelf fungus, lichen and moss…quite a variety. There are little plants coming up through the leaves as well; we’ve been having some warmer days than usual this January.

Here we were on the trail. The trees with brown leaves still clinging are probably young beech trees.

As we came out of the forest there was a great view of the Belmont Manor House from over the rolling hills.

By the time we got back to the Carriage House, we were all ready for a snack!

3 free eBooks – January 2017

Furnishings – butterflies – tiles….3 interesting topics that seem to be my themes for eBooks this month.

Tracy, Berry B. (curator). 19^th Century America Furniture and Other Decorative Arts. New York: The Metropolitan Museum of Art. 1970. Available from Internet Archive here. The objects were included in an exhibit in 1970 – with this book recording it all. I found the ‘other decorative arts’ even better than the furniture.

Weed, Clarence Moores. Butterflies. New York: Doubleday, Page & Company for Nelson Doubleday, Inc. 1927. Available from Hathi Trust here. I liked the vivid colors of the illustrations. Butterflies are generally colorful but the backgrounds were just a vivid in this book. Do you recognize the Tiger Swallowtail?

Campbell Brick and Tile Co. Designs for encaustic and geometrical tile pavements, also of encaustic, glazed, majolic̀a, and other tiles for hearths, fireplaces. Leicester: J. Fleming & Co. 1877. Available from Hathi Trust here. I like decorative tile…great ideas of Zentangles and (maybe) a renovation project for my house!

Ten Little Celebrations – January 2017

January started out with a burst of travel – driving cross country between Maryland and Arizona with a stop for a week in the Dallas area. There were associated ‘little celebrations.’

Leaf earrings from a local artist in McKinney TX – I celebrated finding earrings I like a lot…and if they are created by a local artist that makes it even better. I find it very easy to remember where I purchase earrings so they are great mementos for my travels.

A day on my own – Usually when I travel, my time is full of interacting with other people and I end up exhausted after it continues for too many days. On this 9-day trip, I had one day that was almost all ‘me time’ and I celebrated the lull!

Getting to the hotel in the snow – One day I was out and about in Dallas when it started snowing. I thought it wouldn’t stick but it started before I could head back to the hotel. Dallas does not use salt and there had not been any time for sand to be out either. I was driving an unfamiliar car too. I white knuckled the drive (overpasses particularly) but made it back to the hotel without incident…and celebrated.

Then there were ‘home’ related celebrations:

Home again – I enjoy traveling but coming home again is always a little celebration.

A good night of sleep – I came home from my travels with a cold so the first night that I sleep well was cause for celebration.

A sunny day – January in Maryland has been full of gray skies and drizzle (no snow) so I celebrated one on of the few sunny days.

A new car – Maybe this is a big celebration rather than a little one. I only buy a new car about every 10 years or so…and I’m still savoring the lingering celebration of acquiring the Prius Prime.

There are instances of little celebrations in my favorite activities as well:

Anatomy of the Abdomen and Pelvis Course – This might be the most challenging courses I’ve taken on Coursera – but tremendously interesting. I am celebrating every module. Kudos to the Leiden University Medical School for producing it.

A hike and finding skunk cabbages – I enjoyed a winter hike and was celebrating being outdoors when I found skunk cabbages already up in the winter muck…and that made for a bigger celebration.

Red-tailed hawks – It seems like I am seeing red tailed hawks a lot more frequently this winter….or maybe I am just becoming a better observer. My daughter and I saw them on our cross-country road trip, there is at least one that is frequently the woods behind out house and I saw one at Centennial Park when I was there last week. I celebrate that the birds are thriving and that I am seeing them!

Gleanings of the Week Ending January 21, 2017

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.

What’s Your Sleep Animal? Find out with this quiz. – A little self analysis…about how you sleep. I’m a lion!

What teeth reveal about the lives of modern humans – It turns out our teeth are not adapted very well for modern diets. And it not just cavities and plaque buildup. It also has to do with jaw growth.  Did you know that wisdom teeth (third molar) impaction became 10 times more common after the Industrial Revolution?

The Chemistry of Bodily Fluid Colors – An infographic summarizes how blood, bile, urine, and feces get their color.

Appendix may have important function – I thought the diagram of the appendix shapes of different animals was as interesting as the idea that the appendix may serve as a reservoir for beneficial gut bacteria.

It’s Time to Give Nature the Credit It Deserves – Nature as water infrastructure! Hopefully more areas of the US will include these strategies in their long-term water planning. Good for people, the economy, and the planet!

20 of the Most Stunning Photos Captured by Drones in 2016 – Eye candy that I couldn’t resist sharing.

The Most Precious of Gifts – About gold, frankincense, and myrrh…from the Manchester Museum

The Chemistry of Fireworks Pollution – Wow….there are a lot of bad things that are exploded into the air by fireworks. I’m glad there are efforts to make ‘greener’ fireworks. No one ones a celebration to lead to respiratory problems and exposure to toxic metals.

Designation of Bear Ears National Monument in San Juan County, UT – Some great pictures of one of our newest National Monuments.

Meet Your Newest Organ: The Mesentery – I’m taking a Coursera course on the anatomy of the abdomen and pelvis…and the mesentery is part of the discussion. I just finished a module about how it develops with the gut from an embryological perspective. It’s quite a complex membrane – and now maybe it will be researched as an organ.

Gleanings of the Week Ending January 14, 2017

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 some companies are trying to hire more people on the Autism Spectrum – The pilot programs in companies like SAP and Microsoft are net positive – for the companies and the high functioning autistic people they employ.

Ancient Chaco Canyon population likely relied on imported food – There is physical evidence that timbers, pottery and chert in Chaco came from the Chuska Mountains which are some 50 miles west of Chaco Canyon; corn probably did too. The soils in the canyon and the its tributaries are too salty to grow enough to feed any sizable population.

Researchers record trillions of migrating insects swarming through the skies – A study monitored insects flying over southern England above 500 feet. There were a lot more than expected – insects that move north in the spring and south in the fall. 70% of the migration takes place in daylight hours. A similar study of insect migration has been started in Texas…and had been overwhelmed by the sheer number of invertebrate they are finding!

The Next Big Thing: Healthy Homes – Important to think about for long term health….and maybe not as expensive as it once was.

What have the world’s oldest mummies kept under wraps? – Digital reconstructions of 7,000 year old bodies from South America is in its initial stages. The mummies are deteriorating because of microbes that are more active as the climate of the Atacama becomes more humid.

2016: Compound Interest’s Year in Review –  I like this site…and have included some of these postings when they originally came out…but there were more that were interesting.

United Stated of Cookies – A cookie for each state….and the recipe for it. Maryland is the Berger Cookie.

Scientists can now make lithium-ion batteries last a lifetime – Sometimes small changes make a big difference!

How the world’s biggest cities are fighting smog – There are techniques to take smog out of city air…technologies to apply in parallel with reducing pollution at its source. In many cities – both strategies are urgently needed.

Twelve new tombs discovered in Gebel el Silsila, Egypt – Even with so much focus on archeology in Egypt…there are still new finds.

Grackles and Mockingbirds – Grapevine, TX

Earlier this week I posted some sunrise pictures taken through the hotel window in Grapevine, Texas. I was at the hotel later one day during our stay and enjoyed photographing grackles and mockingbirds through the second-floor window of our room. It was a very cold and breezy day. All the mockingbird pictures show them looking fat with fluffed feathers. It’s always surprising how much bigger and rounder a bird can look when it’s cold.

The grackles (probably Great-tailed Grackles based on their size, tail, and location in north central Texas) didn’t seem bothered by the cold. They are all sleek and full of assertiveness. They seemed to be aware that they were being watched…and they glared back at the camera! Notice how robust the toes/talons are; they make the mockingbird look delicate.

Birding through a window…the way to go on bitterly cold days!

Josey Ranch Lake – January 2017

I saw some of the same kinds of birds I saw back in February 2015 when I walked around the lake last week. It was cold --- and the wind made it feel colder. We did not dawdle but I did manage to take a few pictures. As if 2015: There were lots of Lesser Scaup (the first picture is of 3 males and 1 female) but they were all over the lake with their oddly shaped heads. These birds are only in Texas for the winter.

The Northern Shoveler is also a winter bird.

The swans were still around too. They stay on the lake all through the years.

This time I also noticed American Coots. All About Birds says they are in the area throughout the year but I don’t remember seeing as many of them as I did this year.

There were the Mallards too – another year round resident.

I spotted a Cormorant too.

Finally – the tail and back feathers on this duck seem to glow. It was such a gray day that the feathers stood out. There are also water droplets on the head and breast. I don’t know what kind of duck it is.

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.

Shortest-possible tour of 49,603 sites from the National Register of Historic Places – Who knew there were that many? There is a 38 second movie to show the route for the whole US and then individual state maps. Take a look at your state!

The Scientist’s Year in Review – Links to the cover story and one news highlight for each of the 12 issues.

The Robotic Grocery Store of the Future is Here – Oh no! I enjoy grocery shopping….not sure I want this future. I particularly like picking my own fresh fruit and veggies from the bin.

2016 Year in Science – From Visionlearning. There could be others added…but here are 6 with a succinct description of each.

Vibrant Paintings of Colorful Fish Merged with Their Coral Environments – Eye candy!

Mining 24 hours a Day with Robots – Another example of automation that reduces the need for manpower. The mine where these huge self-driving trucks are used is in Australia….but it could soon be anywhere in the world.

The Best of Cool Green Science 2016: Birds and Birding Edition  and The Best of Cool Green Science 2016: From the Field Edition and The Best of Cool Green Science 2016: Celebrating Nature Near You – Three year end posts from The Nature Conservancy….with great pictures!

3-D Models Capture Endangered Species Before They Go Extinct – A few years ago I too an archaeology course (via Coursera) and they talked about capturing objects with 3-D techniques (notably merging multiple pictures of an object into a rotatable image). This project is doing it with living animals….with a “Beastcam.” There is a link to the slide show about 1/3 of the way through the article.
