Gleanings of the Week Ending December 9, 2023

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.

Restored Glass Negatives Capture Daily Life in 19th-Century New England – Photographs taken from the 1860s to 1930s….Massachusetts…different photographers.

As Temperatures Rise, Dengue Fever Spreads and Cases Rise – The mosquitos that carry dengue viruses are extending their range. There were 0.5 million cases in 2000…5.2 million in 2019. In recent years, dengue has popped up in places it had never been seen, including Afghanistan, parts of Southern Europe, and, this year, Chad. An additional 2 billion people would be at risk of dengue exposure by 2080, compared to 2015. Areas unfamiliar with dengue may be hard hit even if case numbers aren’t high as people won’t have immunity from previous exposure to the virus, and public health systems may not be strong enough to cope with dengue outbreaks.

The World’s Largest Iceberg Is Drifting Three Miles Into the Ocean Each Day - The world’s largest iceberg, which had been grounded on the seafloor since the mid-1980s, is moving away from Antarctica and picking up speed. It could disrupt the foraging of seals, penguins and other seabirds. Called A23a, the iceberg measures around 1,500 square miles—more than 20 times the size of Washington, D.C.—and it’s roughly 1,300 feet thick, making it two and one-third times the height of the Washington Monument. It weighs nearly one trillion metric tons.

Landscape Photography Awards Rewards Authenticity in Photography – My favorite was “Little Leaves”….maybe because it didn’t have time to see a lot with fall foliage this year.

Expansive Alexander Calder Exhibition Opens in Seattle – Take a look at the museum’s site for the exhibit at well.

Bird Photography Contest Celebrates the Unique Diversity of Australia’s Wildlife - Nine winners were singled out for their work, rising above more than 6,000 images that were submitted. My favorite of this group is “Jambalaya on the Bayou.”

Volcano Monitoring Can Be A Risky Business: How Scientists Work Safely - Common PPE used in the field by HVO staff include respirators to filter volcanic gases, gas badges to monitor sulfur dioxide (SO2) concentrations, along with helmets and eye protection.  When molten lava sampling, crews will carry a face shield, fire-resistant clothing, and gloves to protect the wearer from radiating heat.

Best of 2023: Top 42 Photographs From Around the World – I have two favorites in this group of photos: the bald eagles and the dancing mantises!

African Penguins Tell Each Other Apart by Their Polka Dot Patterns – Evidently the chest plumage is unique to each bird….and the birds recognize the dots of their partners!

Photographer Chronicles the Enchanting Life of a Wild Red Fox for 8 Months – A Hungarian photographer’s project at his cottage in the forest after he noticed a fox running under the window one night.

Springfield Art Museum – October 2023

One of my favorite places to enjoy with family that visits me is the Springfield (Missouri) Art Museum. This time it was the backup plan; we had originally planned a visit to the botanical garden, but the day was cold and wet.

The museum was not busy, but we weren’t the only people there. We wandered through the Tradition Interrupted exhibit (August 19-November 12). I enjoyed the pieces….recognizing many of the traditions and enjoying the descriptions about the way they were interrupted. Trying to capture the pieces photographically is always part of a museum visit for me; I keep a small camera that fits easily in my purse rather than lugging my bridge camera; it provided optical zoom giving me more options than my phone does. My favorite piece in this gallery is one called Teardrop (middle image below)…a metal piece that imitates embroidery or lacework. The lighting is part of the work and I was only able to capture the shadows immediately behind it; there were also shadows on the ceiling and floor!

The museum is also hosting a series of exhibits in collaboration with Missouri State University. The one showing now is titled Blue on White (July 22 – December 3) – featuring Chinese ware (with connections to Persia)…appropriated through imitation and export to Japan, Europe, and the Americas. Curated by MSU students.

The Creating an American Identity exhibit is a semi-permanent rotating exhibition from the museum’s collection of over 10,000 objects. The middle one below is an early Jackson Pollock – created in the 1930s before he became famous for ‘drip’ paintings!

There is a copper sculpture that I’ve seen every time I have visited the museum. It is difficult to photograph because the background is always so cluttered. This view is about as good as it gets!

The Survey of Ceramic Art is also a semi-permanent exhibit. Even if many of the pieces are ones I’ve seen before, I like ceramics so much that it is probably my favorite exhibit/gallery in the museum. This visit, I thought about how lighting of objects makes a big difference….but often reflections from glass cases is problematic; it’s more apparent in photographs but it distracts even when simply viewing the pieces.

I waited until the end to photograph the Chihuly chandelier in the foyer of the museum. It’s titled Autumn Persians and Feather Chandelier. I zoomed in to eliminate a spotlight; the lighting of the piece is required…but it can also be a distraction.

Most of the plantings around the museum were fading fast…and it was too wet to walk around for botanical photography.

The museum was a great way to spend a wet fall afternoon!

Gleanings of the Week Ending October 21, 2023

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.

Intact Roman-Era Sarcophagus Discovered in France – From the 2nd century AD, sealed with iron clasps, weighs about 1,700 pounds. It hasn’t been opened yet, but x-rays and an endoscope camera have revealed the contents.

Selective removal of aging cells opens new possibilities for treating age-related diseases - Aging cells, known as senescent cells, contribute to various inflammatory conditions and age-related ailments as humans age. The researchers created technology that specifically targets organelles within aging cells to initiate the cell’s self-destruction. There is still a lot of work to be done (and preclinical and clinical trials).

Cloud Rings Around a Volcano Takes Top Prize in ‘Weather Photographer of the Year’ Contest – Capturing dramatic weather moments…

Brainless Jellyfish Are Capable of Learning - Experiments that provide evidence that box jellyfish are capable of associative learning, or the process of linking two unrelated stimuli together.

How maps can protect children from extreme heat - Heat is becoming increasingly dangerous and it's a threat that is not going away. Community heat maps may not solve the long-term problem, but they are a step in the right direction, by providing awareness and empowering vulnerable children and their families.

Stunning 16th-Century Turkish Bath Reopens in Istanbul - Called the Çinili Hamam, the revitalized site won’t offer traditional bathing until 2024. In the meantime, however, it will feature private gardens and contemporary art in the newly discovered Byzantine cisterns that originally fed the baths. Nearby, a new accompanying museum will display objects associated with traditional bathing rituals—including towels, bowls and ornately decorated wooden shoes—and explain the baths’ original water and heating systems. It will also showcase artifacts from the Byzantine, Roman and Ottoman periods uncovered during the restoration.

The Resiliency of Urban Wildlife - Four distinct sets of traits that help urban wildlife adapt and survive in environments that seem hostile to animals: diet, body size, mobility, and reproductive strategy. Important to know since if you look at the traits animals are adopting to survive in urban environments, you can see how cities could be modified to become more habitable to a wider variety of species.

See the Trove of Ancient Treasures, including a Shrine to Aphrodite, Just Discovered in an Underwater City Off the Coast of Egypt - Thonis-Heracleion was Egypt’s biggest port for centuries, before being surpassed by Alexandria. The city was eventually lost thanks to a combination of rising sea levels, earthquakes, and tsunamis, disappearing beneath the waves along with a large section of the Nile delta. It was largely forgotten for centuries, until 21st-century archaeologists began investigating.

New Patch Inspired by Octopus Suckers Could Deliver Drugs Without Needles - A tiny, drug-filled cup that sticks to the inside of the cheek like an octopus sucker. The device is easily accessible, can be removed at any time and prevents saliva from dissolving the drug, which gets absorbed through the lining of the inner cheek.

Buried ancient Roman glass formed substance with modern applications - Photonic crystals were created by corrosion and crystallization over centuries. If we could significantly accelerate the process in the laboratory, we might find a way to grow optical materials (i.e. materials for communications, lasers, solar cells) rather than manufacture them.

Missouri Botanical Garden – Chihuly

I enjoyed the Chihuly glass exhibition at the Missouri Botanical Garden the second time as much as I did the first time…. photographing the pieces during the day and then in the evening. There were some differences between the two visits.

My husband was enjoying photographing them too, so the pacing of our visit was slower around the glass than it had been with my daughter (who did not bring a camera other than her phone).

It rained for about 30 minutes during the Chihuly Night event! We spent most of it in the visitor center then made a quick round of the pieces we wanted to see when it stopped – with lightning in the distance. It was not a leisurely stroll…rather an exhaustive power walk between the glass installations.

The lightning for the Chihuly night was not as robust. It seemed that the lights were configured at the beginning of the installation and then not maintained for the duration of the exhibition (i.e. some were poorly illuminated during the second visit).

I attempted to capture the structure within the glass more than I did the first time.

The Fiori boat has a lot of interesting shapes that I hadn’t noticed during the first visit!

Last time, I photographed the yellow glass on the rose garden arches…but didn’t realize that they were owned by the garden and not in the exhibit brochure. I remembered to look for the name of the piece in this second visit: Trellisses.

I’m glad we made the effort to go again…in September when the Chihuly Nights were still being offered. The exhibition will end in mid-October. Next time I visit the garden, I want to tour the Tower Grove House!

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.

Four key questions on the new wave of anti-obesity drugs – Several of the drugs were originally developed to treat type 2 diabetes but now are popular weight loss drugs.

Sweet smell of success: Simple fragrance method produces major memory boost – A study done by the University of California, Irvine on older adults…participants reaped a 226% increase in cognitive capacity compared to the control group. A product based on their study and designed for people to use at home is expected to come onto the market this fall.

How the US is fighting back against deadly floods – Identifying flood plains…not building back in them after a flood.

Old-Growth Trees, Some Dating To 17th Century, Protected at New River Gorge – The Burnwood Loop – where I want to hike first in the New River Gorge National Park and Preserve!

Does Cooking with Gas Stoves Hurt Indoor Air Quality? – Yes…but how much is the better question. 12.7% of current childhood asthma in the United States is attributable to gas stove use.

A quick look inside a human being – Magnetic Particle Imaging (MPI)…using a portable scanner to visualize dynamic processes in the human body such a blood flow.

Why it's so important to figure out when a vital Atlantic Ocean current might collapse - Humans are changing the fundamental processes of the Earth faster than we can understand them. The collapse of the current would have effects around the planet: temperatures in Europe would fall, heat in the tropics would rise, rainfall would decrease across the Sahel in Africa, the summer monsoon would weaken across Asia, and sea levels would rise even faster in the eastern US.

New Thermal Activity on Geyser Hill in Yellowstone National Park – Short video from the Yellowstone Volcano Observatory.

‘Perfectly Preserved’ Glassware Recovered From 2,000-Year-Old Shipwreck – The shipwreck was located 1,148 feet below the surface in waters between Italy and France. Two remotely operated vehicles (ROV) were used to scan the site and recover artifacts.

Short bursts of daily activity linked to reduced cancer risk - A total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers (i.e. cancers associated with physical activity such as liver, lung, kidney, gastric cardia (a type of stomach cancer), endometrial, myeloid leukemia, myeloma, colorectal, head and neck, bladder, breast and esophageal adenocarcinoma (cancer of the esophagus) by up to 32 percent.

Chihuly (glass) in the Missouri Botanical Garden

My daughter and I made big plans to see the Chihuly pieces in the Missouri Botanical Garden in late June. We made reservations a week in advance to see the gardens (and glass) at night on our first evening in St. Louis…and then planned a daytime walkabout on our last morning. We got to the gardens a little after 6 PM to have dinner in the garden restaurant (Sassafras) and the enjoyed the gardens until about 9:30 PM…from dust to dark. For our morning visit we arrived shortly after the gardens opened. I took pictures frequently…managed to photograph all the Chihuly works listed in the brochure plus 3 more. It was well worth the effort to see the glass several times…in varying light. Enjoy the images….and plan a visit to the gardens if you can! (Note: To see larger images click on any of the images in this post)

I am already contemplating going again. The special Chihuly Nights go until late August…the exhibit itself continues until October 15.

Mound City Glass (historical catalog)

The 1889 catalog of the Mound City Glass Company in St. Louis, Missouri showcases ornamental glass offerings. They did beveling, sand blasting and embossing….as well as having a stock of plate glass.

Catalogue from the Mound City Glass Co.

 Old catalogs reflect the availability and popularity of wares…become a historical record of consumerism of the period. In the late 1800s, the country had a wide range of housing from sod structures to the first skyscrapers. People needed windows to provide light inside those structures so improvements in plate glass production during the 1800s was welcomed. The type of glass produced by the Mound City Glass company must have been popular for anyone with enough money to purchase it…letting light in along with providing a decorative element.

There isn’t much information about the company other than the catalog. The address on the catalog was in downtown St. Louis…maybe the offices/showroom rather than where the glass work was done.  I assume that the ‘mound city’ in the name came from Cahokia mounds which are on the eastern side of the Mississippi across from St. Louis. There are places in Kansas, Missouri, Illinois, and South Dakota named Mound City; the one in Missouri is on the other side of the state - north of Kansas City close to the Missouri River; the one in Illinois is in far southern Illinois on the Ohio River which is their border with Kentucky; it doesn’t seem likely that either one would have been the location of the original manufacturing facility.

Gleanings of the Week Ending May 6, 2023

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.

Digesta: An overlooked source of Ice Age carbs – Partially digested vegetable matter from large herbivores (such as bison) might have provided carbohydrates and other macro nutrients reducing the burden of ‘gathering’ for a time after an animal was slaughtered. Perhaps during migration, it was the dominant source of carbohydrates in a situation with reduced accessibility of plants. And maybe women participated in hunting to a larger extent than previously thought; ‘grave goods’ in burials found that perhaps 30-50% of all large-game hunters in the Americans during the late glacial era may have been female!

Anemia found to be common in ancient mummified Egyptian children – CT scans were done on 21 child mummies (between ages 1-14 at death) to study the skeleton inside the wrapped remains. 7 of the children had pathological enlargement of the cranial vault, typically associated with anemia. The study also found a child that died less than a year after birth of thalassemia (the body could not produce hemoglobin).

Bathing through the ages: 1300 – 1848 – 14th and 15th century bathhouses provided services beyond bathing (lancing abscesses, pulling teeth, steam rooms, mineral baths, cupping, herbal concoctions); they helped shape the public health services of larger cities as they grew, and health conditions deteriorated. By the 16th century, bathhouses started to disappear as Europe was ravished by plague, smallpox, and syphilis. But – by the 1800s, sanitation reformers were arguing that making bathing facilities available to the poorest classes of society offered an ‘affordable and immediate way’ of improving public cleanliness and health. Bathhouses, along with waterworks and sewage systems, laid the foundation for the UK Health Act of 1848.

Glass or Plastic: which is better for the environment? – There is not a clear-cut answer. I will lean toward glass because of its non-toxicity….but I also realize we need to improve the ways we use it (less single use) and recycle it (better sorting and improved processing that avoids melting it twice),

Greener batteries – Batteries with Organic Electrode Materials (OEMs) are one alternative that is being researched…in this case using azobenzene by a research team at a Chinese University. Hopefully there are researchers around the world also focused on producing greener batteries.

Protein powders: When should you use them? – I think of protein powder as an ultra-processed food….a food I only want to use if I can’t manage to get enough protein from unprocessed or lightly processed foods in my diet. It is not something I want to use every day!

Long Reviled as ‘Ugly,’ Sea Lampreys Finally Get Some Respect – Not so long ago…lampreys were an organism that seemed destined for extinction because we only saw it as a predator that wiped out the Great Lakes lake-trout fishery. Now, the consensus is that, in their natural habitat, marine lampreys are “keystone species” supporting vast aquatic and terrestrial ecosystems. They provide food for insects, crayfish, fish, turtles, minks, otters, vultures, herons, loons, ospreys, eagles, and hundreds of other predators and scavengers. Lamprey larvae, embedded in the stream bed, maintain water quality by filter feeding; and they attract spawning adults from the sea by releasing pheromones. Because adults die after spawning, they infuse sterile headwaters with nutrients from the sea. When marine lampreys build their communal nests, they clear silt from the river bottom, providing spawning habitat for countless native fish, especially trout and salmon. Wow!

The Pacific Garbage Patch Is Home to Coastal Species—in the Middle of the Ocean – A surprise for researchers…they found shrimp-like arthropods, sea anemones and mollusks, Pacific oysters, orange-striped anemones and ragworms. Crustaceans were taking care of eggs and anemones were cloning themselves. This does not make the Garbage Patch acceptable!

Photography In the National Parks: Same Spot, Different Time / Season / Weather – Spots in Yellowstone, Mount Rainier, and Olympic National Parks.

Greater fat stores and cholesterol increase with brain volume, but beyond a certain point they are associated with faster brain aging – People in wealthy countries have largely grown accustomed to eating more and exercising less -- habits that are associated with decreased brain volumes and faster cognitive decline. This study looks at indigenous people (two tribes in Bolivia that live along tributaries of the Amazon). The tribe that was closer to our subsistence ancestors had the lowest rates of hear disease and minimal dementia; in this group - BMI, adiposity and higher levels of "bad" cholesterol were associated with bigger brain volumes in older adults!

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.

Farmers Find Wild African Cat Wandering Around Missouri – A serval found when a farming family set a live trap to capture the culprit leaving bones and feathers between their stacks of hay bales! The Turpentine Creek Wildlife Refuge came to the rescue. This is all close to where I live and I was saddened that evidently the new Big Cat Public Safety Act does not include the smaller non-native wild cats…and that someone was cruel enough to release this cat of the African savanna into the wild in Missouri.

Caribou have been using the same Arctic calving grounds for 3,000 years – Analysis of antlers found on the tundra….discovering some of them are 3,000 years old! But the Arctic is warming faster than other parts of the globe. The elders of the village south of the calving grounds comment that they have noticed a lot more trees, less barren tundra. What will happen to the barren ground caribou as this habitat gets converted to forest?

Why fabric fraud is easy to hide – The fashion supply chain is fragmented and very dense….most apparel companies do not track their own supply chain (or don’t go past their immediate suppliers). Organic cotton is one of the prime examples of how end products labelled as organic cotton…might not be. It is hard to determine where the fraud is inserted in the process; the result is that the consumer is paying a premium price…not getting what they are paying for. And to improve the system will require big changes in the fabric/apparel business.

A Field Guide to Unexpected, Out-of-Place Wildlife – Sometimes animals have ranges that are changing or are a lot larger than we anticipate…sometimes birds are in very different places that their usual range!

Dirty Laundry: How much microfiber do we emit with our laundry – A study done in the UK…but probably relevant to the US as well. Microfibers from laundry in the UK weigh 6,850 to 17,847 tons per year. Yes…that’s a lot and pollutes water…however, it is a dwarfed by the 365,000 tons of clothing going into UK landfills per year.

Antibiotic use in farming set to soar despite drug-resistance fears – The increase in bacterial infections that cannot be treated with antibiotics (because of bacteria developing resistance to antibiotics) has been growing in recent years. Overuse of antibiotivs in agriculture is thought to be a major driver of the problem. Governments around the world have attempted to curb the use of antibiotics to promote growth but the use is still expected to grow by 8% between 2020 and 2030. The article includes a chart of agricultural antibiotics by country in 2020…and a projection for 2030.

The Lifelike Glass Models of Leopold and Rudolf Blaschka – Thousands of realistic models of plants and sea creatures made by a father and son from the 1860s until 1938.

8 everyday foods you might not realize are ultra-processed – and how to spot them – I am cutting back on ultra-processed foods this year. Some of the 8 listed in this article are easy: I don’t eat breakfast cereals, I only eat protein bars as ‘emergency rations’ (i.e. not frequently) and avoid yogurt, meal bases and sauces, processed meats, and margarine. I’m still looking for a soy milk that has fewer ingredients; will give up on soy milk soon if I don’t find one. And I try to buy bakery bread.

Did Philip II bring invasive fish to Spain? – Evidently his efforts to acquire fish and crayfish from afar spanned at least 25 years!

Study reveals that much still not known about cognitive decline - Data came from 7,068 participants in the 1996-2016 Health and Retirement Study. Participants were born between 1931 and 1941. Researchers measured their cognitive functioning at age 54 and how it declined until they were 85. At age 54, socioeconomic status, education and race -- explained only 38% of the variation in functioning. Those same factors explained only 5.6% of the variation in how quickly cognitive functioning declined in people between age 54 and 85. So much we don’t know about cognitive decline although it is pervasive in older adults, even those without dementia.

Unique Aspects of Days - July 2022

Settling into our new home in Missouri is still prompting unique aspects of our days!

1st doctor’s appointment in Missouri. Getting medical records transferred from a specialist in Maryland to a new specialist in Missouri was a first for me…and I was pleasantly surprised that it happened so easily and that the new doctor continued the monitoring/treatment as I expected.

Callery Pear to the recycle center. It was a unique experience to discover a pear tree growing in a crepe myrtle in a front flower bed of my new house. I cut it down…discovered it had thorns…and was very pleased to get it cut up enough to fit in the back of my car and then to the recycle center yard waste bins without injuring myself. It was an experience I hope is unique!

Unpacking the art glass. I packed it but my husband unpacked it. There was a joy in packing and unpacking the beautiful pieces….savoring them individually and then again as a whole in the display cabinet. We left 2 pieces that are on light stands out on a desk beside the piano to act as ‘night lights’ in that part of the house. It has been over 25 years since we enjoyed the glass the way we did in July.

Making a compost ring with cedar edging. I bought two sections of edging made with 3-6 inch vertical lengths of cedar branches and formed a circle to hold my kitchen scraps and soft yard waste under one of our pine trees. There is not enough material to require a bigger compost bin so this is a relatively unique solution. I’m not sure whether I will move the ring once the compost is deteriorating enough to continue as a pile without the ring or ready to spread out. There is space to move the ring and start another collection nearby.

Finding the camera battery charger. It seemed like there were about 5 times this month where we came close to panic because we couldn’t find something we needed in our new home. The one that had me most worried was not knowing where the charger was for my camera battery; luckly I found it after an hour or so of hunting through boxes. Now that we have unpacked most of the boxes, it is less likely to occur…making this particular kind of anxiety unique to July 2022.

Forgot my toiletries. I travel frequently enough that I rarely forget anything I need…but I did for our trip back to Maryland for the closing on our house there! The compartment bag for toiletries was left hanging on the bathroom door in Missouri. I quickly bought essentials…glad this event was unique in my travels.

Hot and dry Josey Ranch lake. The lake at Josey Ranch near where my parents live was lower than I’ve seen with deep cracks where there is usually water or mud. The cattails area is dry and other plants are taking over. I hope this is unique and not what it will be like every summer from now on in Carrollton TX.

Hummingbird moth. I was surprised…glad I had my camera with me…when I spotted a hummingbird moth at the Springfield Botanical Garden. They are fun insects to watch and I always feel priviledge to see even one a year.

Hummingbird outside my office window…on the crepe myrtle. I looked out my window one morning and saw a hummingbird checking out the crepe myrtle outside my office window. It was the first I’d seen in our Missouri yard.

Missouri watermelon at the Carrollton (TX) Walmart. I noticed that the watermelon I bought for my parents in the Carrollton Walmart had been grown in Missouri…and discovered when I got home to Missouri – the watermelons in the Walmart were from Missouri too!

Dillon, Edward. Glass. New York: G. P. Putnam’s Sons. London: Methuen and Co. 1907. Available from Project Gutenberg here. The book is a history of glass (up until the early 1900s) with illustrations of pieces in museum collections. I paid more attention to the illustrations than the text. I’ve always been interested in ancient glass because it points to the step beyond basketry and pottery in our manufacturing expertise. It a material we think about as being ‘breakable’ but is often very enduring.

Whitney, Frederick. Blackboard Sketching. Springfield, Massachusetts: Milton Bradley Company. 1909. Available from Internet Archive here. Written at a time when many students were learning to write and draw with blackboard slates and slate pencils…it provides an idea of how students were taught. Early classrooms used a lot less paper!

LaFontaine, Bruce. Bridges of the World Coloring Book. Dover Publication. 1994. Available from Internet Archive here. The bridges are organized chronologically. The sample image I show below is the colored version (as the end page of the book) of page 10…a bridge from China built about 1100. The book includes short descriptions the design features and technologies the bridge builders utilized. Obviously, these bridges have proven to be very durable.
