Rhododendron

/

Our rhododendron bloomed profusely this year – no frost damaged buds like last year. The whole bush was covered with blooms. It started in mid-April and all the buds had opened by the first few days of May.

I couldn’t resist a round of macro shots. It was good experience with my new iPhone 15 Pro Max. I like the individual flowers, the flower clusters, the new growth – it is full of photographic opportunities. The bush seems to be growing a lot better this year too; maybe it has recovered from the big drought the summer we moved to Missouri.

Do rhododendrons make good cut flowers? I did a search and discovered that yes…to cut a cluster with some unopened buds and slit the end of the stalk to allow easier water uptake. I put the cluster in a wine glass my parents got for their 50th wedding anniversary from a couple they had met in college and remained friends through the years….savored the flowers in my office.  All the buds eventually opened just as they would have outdoors.

I also learned that sometimes rhododendron need to be pruned but it won’t be this year…and maybe for years to come. My bush is in a place where it can expand in almost every direction. I will probably cut more flower clusters next spring now that I know how well they last indoors and, I guess, that will be the extent of the ‘pruning’ done!

Then and Now – Family

/

In the 1960s, I was growing up in a large extended family. My mother had 8 siblings and my father, an only child, was close to his cousins. Most of our traveling was to visit family. By the time I was in elementary school, my parents had a second car, and my mother took us to her parents’ home for a week or so during the summer to see the aunt and uncles…continuously growing number of cousins. I remember my grandfather’s construction projects that included a covered patio/carport with a very long table and bench overlooking a large elm where he’d fashioned a table and benches to fit neatly around its large trunk. We ate every meal aside from breakfast outdoors! There was also a large barbeque pit with a huge grill and an oven built into the chimney. He built a fountain of natural stone near the garden…the swimming pool was a little further away. Prior to the swimming pool being built, he often found a river suitable for swimming for all the aunts and cousins….and he would do some fishing. I enjoyed one-on-one time with my maternal grandmother at her work (she owned/ran the mill); I remember her writing letters to one of her daughters that lived far away over a few days before deciding it was long enough and sending it off.

 My paternal grandparents moved to live near us in the late 50s, so I saw them very frequently – lots of good food, gardening, crocheting, sewing, dominoes and checkers. We saw my dad’s extended family at gatherings held at his paternal aunt’s house. I remember my great aunt had hollyhocks beside her porch. We visited his maternal aunts (and grandmother) that lived in the same town. I associate my great-grandmother with chocolate covered graham crackers and her daughters with plants (my grandmother had a number of plants that she received originally from her sisters).

The food was always plentiful and included veggies from the garden. The paternal side of the family also cooked Czech desserts (kolaches!).

Now the family is significantly smaller. I have 3 sisters and am the only one that lives further away; only 1 of my sisters has children so the number of cousins is small. My husband had 2 sisters, but they are already gone as is his extended family. My sisters and I are transitioning from a relationship that has be very focused on caring for our parents over the past few years – not yet settled into a new normal without our mother. I am not close to my cousins although I have been seeing 3 of them more frequently at funerals recently…realizing that we have in common our adjustment to life after long-lived parents die.

I drive from my home in Missouri to visit my dad near Dallas once or twice a month in his assisted living home. My daughter goes with me sometimes. One sister visits him almost daily. The other two visit once or twice a week when they are town. I try to see at least one of them when I visit Dad. Two of them have visited us in Missouri. We text each other frequently – mostly keeping each other informed about what is happening with Dad. There are infrequent emails, phone calls, or zoom meeting. I enjoy my access to a frequently updated cloud folder of great nephew pictures. The way we keep in touch when we are not together has changed significantly since the 1960s!

Food had changed as well. We seem to all have foods we are avoiding now (and the problematic foods are not the same!)…and desserts are not something we want as frequently. We tend to go to a restaurant for special occasions more often then eating at home.

Dickerson Park Zoo – April 2024

/

My first trip of the season to the Dickerson Park Zoo was back at the end of March (post 1, post 2); my second was near the end of April when my sister and brother-in-law visited. Like the first visit, there were lots of peacocks wandering through the zoo; this time there were peahens too and there were some instances where it looked like the birds were either already incubating eggs…or getting a ‘nest’ ready. There was a male just past the entrance that was actively displaying for a peahen…moving both the upright tail feathers and the supporting structures behind the big tail. The birds were also vocalizing the whole time we were at the zoo.

Daffodils were replaced with irises blooming in clumps along the walkways and the sides of the stream.

I enjoyed the enclosure for flamingos, roseate spoonbills, and scarlet ibis.

There was one flamingo that was sitting and kept its head in the dirt…perhaps not feeling so well. All the other birds seemed to be active (particularly the spoonbills) and enjoying the afternoon.

I zoomed in on some feathers that had been shed in the enclosure. It is interesting that the feathers are white toward the base….very colorful in the part furthest from the body of the bird (when attached).

The trumpeter swans were on the pond as they were last time – perhaps a little perturbed by the tree trimming that was happening nearby.

Both the cheetahs and lions were out – and one of the cheetahs was moving around a lot. It could have been responding to the extra noise.

One bongo was relaxing while the other nibbled at leaves.

I zoomed in on the elephant’s eye – realized that they are amber in color. A keeper came to give hay to the elephant and asked if we had questions. I asked if all elephants have amber eyes and evidently that is the eye color for Asian elephants. The elephant is named Patience and she is a geriatric elephant; she likes to be alone rather than with the other female (they don’t get along).

I took another picture of the little elephant sculpture…probably my favorite sculpture at the zoo. I think the shiny top of its head is where people touch it the most!

It was starting to sprinkle but we wanted to see the giraffes. One of the young ones was intent on getting some grass near the fence.

My brother-in-law became mesmerized watching a little girl held by her mother feed the giraffes romaine lettuce; she was an expert…must do it frequently.

We headed back to the zoo store where my sister bought one of almost every item shaped like a turtle! It was a good finale for our visit to the zoo.

Gleanings of the Week Ending May 4, 2024

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.

Do societies grow more fragile and vulnerable to collapse? - The world is hardly immune to increasing inequality, environmental degradation, and elite competition – all factors which have been proposed as precursors to collapse earlier in human history. Industrialized production, enormous technological abilities, as well as professional bureaucracies and police forces will all likely create more stable, resilient states. However, our technology also brings new threats and sources of vulnerability, such as nuclear weapons and the faster spread of pathogens. We also need to be wary of celebrating or encouraging the entrenchment of authoritarian or malevolent regimes. Resilience and longevity are not de-facto positive.

Solving the riddle of the sphingolipids in coronary artery disease - Boosting levels of a sphingolipid called S1P in artery-lining endothelial cells slows the development and progression of coronary artery disease in an animal model.

“Porcelain Gallbladder” Identified in Mississippi - Identified among a woman's 100-year-old bones exhumed from the cemetery at the site of the Mississippi State Lunatic Asylum. A porcelain gallbladder forms through calcium build-up in the wall of the organ, which causes it to harden.

World's chocolate supply threatened by devastating virus – Oh no! About 50% of the world's chocolate originates from cacao trees in the West Africa countries of Ivory Coast and Ghana. The damaging virus is attacking cacao trees in Ghana, resulting in harvest losses of between 15 and 50%. Farmers can combat the mealybugs the spread the virus by giving vaccines to the trees to inoculate them from the virus. But the vaccines are expensive, especially for low-wage farmers, and vaccinated trees produce a smaller harvest of cacao.

WHO redefines airborne transmission: what does that mean for future pandemics? - Virologists now acknowledge that SARS-CoV-2 spreads mostly by airborne transmission of small particles that are inhaled and that can remain in the air for hours — a method that was previously called ‘aerosol’ transmission. It also spreads by larger ‘droplets’ of virus-containing particles on surfaces, including hands, or ejected over short distances. The WHO document sets an important benchmark for how the world responds to the next pandemic. “The next pandemic will most likely be a respiratory virus again because that’s normally the pathogen that mutates the fastest.” The report’s clarity around transmission will help public health providers to respond appropriately. “They will then consider masking early, they’ll consider ventilation early, they’ll consider all these precautions early because a precedent has been set already.”

Human muscle map reveals how we try to fight effects of aging - As we age, our muscles progressively weaken. This can affect our ability to perform everyday activities like standing up and walking. However, this study also discovered for the first time several compensatory mechanisms from the muscles appearing to make up for the loss.

USDA announces new school meal standards that call for less sugar, salt in students' food - Schools also have the option to require locally grown, raised or caught agricultural products that are unprocessed, while the new standards limit the percentages of non-domestic grown and produced foods that schools can serve to students.

Plastic-choked rivers in Ecuador are being cleared with conveyor belts - Azure system's simple design has the capacity to stop and collect around 80 tons of plastic per day. At this particular point in the San Pedro River, the most it's collected in a day has been 1.5 tons of plastic and synthetic fabrics – that's roughly the same weight as a female hippopotamus. The Azure system is a boom device that stretches across the river to stop objects floating on the surface. It extends down 60cm (2ft) into the water, allowing fish and other organisms to move freely below, and is placed at an angle allowing the natural water flow to direct all debris into one corner of the riverbank.

First glowing animals lit up the oceans half a billion years ago - Some 540 million years ago, an ancient group of corals developed the ability to make its own light. Bioluminescence has evolved independently at least 100 times in animals and other organisms. Some glowing species, such as fireflies, use their light to communicate in the darkness. Other animals, including anglerfish, use it as a lure to attract prey, or to scare away predators. However, it’s not always clear why bioluminescence evolved. Take octocorals. These soft-bodied organisms are found in both shallow water and the deep ocean, and produce an enzyme called luciferase to break down a chemical to make light. But whether glowing octocorals use their light to attract zooplankton as prey or for some other purpose is unclear.

Peatlands Are One of Earth’s Most Underrated Ecosystems - Peatlands are spongy, waterlogged soils composed in part of decaying plant matter. They’re found all around the world, and despite covering only 3% of Earth’s surface, store around 30% of all the carbon on land.

Springfield Botanical Gardens – April 2024

/

I made my second visit to the Springfield Botanical Gardens in late April when one of my sisters was visiting; my husband and I had gone to the Kite and Pinata Festival earlier in the month. The tulips had been in full bloom during the first visit. There were a few left in late April, but the irises and columbines were the big show. I noticed some native honeysuckle and clematis blooming as well. I made it a goal to make a walk around the gardens at least once a month until cold weather comes again next fall. There will always be something new to see.

My sister and I walked through the Mizumoto Japanese Stroll Garden after viewing the gardens close to the Botanical Center building. I used my Friends of the Garden membership in lieu of the admission fee. I made a small cairn on one of the posts near the rock garden…this time choosing the same type of stone for all three rocks.

The Japanese lanterns are always some of my favorite photographic subjects in the garden. I like the greenery around many of them. The pines are there all year round, but the grasses and yellow iris are only around during the warm months.

The yellow iris grow around the ponds – along with the bald cypress knees that always make the water’s edge look more interesting.

It was a good way to spend a couple of hours….enjoy the beautiful gardens and get in some steps for the day!

Ten Little Celebrations – April 2024

/

April 2024 has been even more full of little celebrations than usual; it was challenging to choose the top 10!

Traveling with my daughter. Taking a road trip to Dallas (a familiar trek) is quite different when my daughter to with me. We start the driving a bit later and, this time, we stopped in Joplin on the way home for lunch. I celebrated the time in the car…the great conversation.

The life of a cousin. It was bittersweet to go to the funeral of a cousin that was younger than me…but it was clearly a celebration of her life.

20 puzzles for $2 each. The Friends of the Library book sale in my county included puzzles and I celebrated getting 20 of them for my dad and the other residents at his assisted living group home. I also celebrated a return to volunteering - helping with the book sale.

iPhone 15 Pro Max. Getting a new phone is always cause to celebrate….even though I started out a little anxious that it would a little challenging to go from my old Android phone to an iPhone; it was a pleasant surprise to realize it was pretty easy. The only downside was the reduced functionality of the Windows phone link app for text messages; that issue was resolved as soon as I transitioned to a Mac later in the month.

MacBook Air 15”. More new technology I am celebrating; it only took about 24 hours for me to become a fan of the Mac after using Intel-based machines since the 1980s.

Irises. The plants bloomed all at once. In one bed the stalks were too tall for them to remain standing to I cut them to enjoy indoors – celebrated the buds opening all along the stems.

14 ducklings. Seeing Mom Mallard with her ducklings is a great celebration of spring.

Solar Eclipse. So glad we made the effort to position ourselves to see a 2nd solar eclipse (the 1st for me was in 2017). It’s a phenomenon rare enough to be a celebration.

Belted Kingfisher. Celebrating a bird I didn’t expect to see around our neighborhood pond.

Kite and Pinata Festival. The botanical garden is a great place for outdoor celebrations like this.

Gleanings of the Week Ending April 27, 2024

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.

Meet the World’s Largest Freshwater Crayfish – The Tasmanian giant crayfish. Their numbers are declining due to fishing and disturbance.

FDA urges Congress to pass bill mandating food manufacturers test for lead – I am surprised Congress did not pass this already. According to the U.S. Disease Control and Prevention, there have been at least 519 confirmed, probable and suspect cases of lead and chromium poisoning traced to imported applesauce pouches produced by brands WanaBana, Schnucks and Weis. Lead exposure in children is associated with learning and behavior problems, as well as hearing and speech issues and slowed growth and development.

Retention ponds can deliver a substantial reduction in tire particle pollution - The presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. Tire wear particles significantly outweighed other forms of microplastics, such as plastic fibers and fragments.

Climate change is fueling the US insurance problem – I’ve seen more articles about this recently….there is no good news re insurance…nothing that can overcome what climate change is doing. One state-level action that could help mitigate the impacts of climate change is the implementation of flood disclosures. Organizations like the Natural Resources Defense Council have urged states to require flood disclosure polices during property sales to help buyers decide whether buying is worth the risk. Research has shown disclosure can devalue flood-prone properties and discourage development in risky areas. Even though the number of states requiring flood disclosure policies is slowly increasing, Florida remains noticeably absent, and one-third of states still have no requirement that sellers must disclose a property's flood risk to potential buyers.

Does the time of day you move your body make a difference to your health? – Maybe – for people living with obesity.

How the iron lung paved the way for the modern-day intensive care unit – The iron lung was first used to save the life of a child in 1928. It swiftly became a fixture in polio wards during the polio outbreaks of the subsequent decades, particularly from 1948 until the vaccine was developed in 1955. And its creation paved the way for many subsequent medical innovations. Some patients spent just a short time in the iron lung, perhaps weeks or months until they were able to regain chest strength and breath independently again. But for patients whose chest muscles were permanently paralyzed, the iron lung remained the key to survival.

Food security in developed countries shows resilience to climate change - Data on American wheat production, inventories, crop area, prices and wider market conditions from 1950 to 2018, together with records of annual fluctuations in the weather for the same period reveals strong evidence of an increase in weather and harvest variability from 1974 onwards. However, Wheat prices remain relatively stable, along with the price of associated goods mainly due to farmers and agricultural industries providing a buffer, smoothing out any bumps in the supply of grain to retailers and consumers.

Where the Xerces Blue Butterfly Was Lost, Its Closest Relative Is Now Filling In - Silvery Blues collected 100 miles south of San Francisco were released at a restored a swath of dunes in the Presidio, a former military base, trying to bring back native wildlife. They will pollinate native flowers and form a critical link in the food chain there.

Colorless, odorless gas likely linked to alarming rise in non-smoking lung cancer - 5-20% of newly diagnosed lung cancers occur in people who have never smoked, many of whom are in their 40s or 50s.  Non-smoking lung cancer cases is likely linked to long-term, high exposures of radon gas. This colorless, odorless gas is emitted from the breakdown of radioactive material naturally occurring underground that then seeps through building foundations. The gas can linger and accumulate in people's homes and lungs silently unless they know to test for it. We had our Missouri house tested and radon remediation installed before we moved it!

Contents of Roman Lead Coffin Examined in England - The examination of the contents of a Roman lead coffin discovered in 2022 in the city of Leeds has identified the partial remains of a child (about 10 years old). The initial evaluation of the coffin’s poorly preserved contents found the remains of a woman between the ages of 25 and 35 at the time of her death some 1,600 years ago, a bracelet, a glass bead necklace, and a finger ring or an earring.

Irises and other Yard News – April 2024

/

The irises, that were already growing in flower beds when we bought our house, are blooming profusely; the ones I transplanted last fall/winter will take another year to build up the energy to bloom. I was surprised that the most prolific bed this year grew very elongated stems that fell over as soon as they started to bloom; I didn’t remember them being so tall last year. The irised in another bed looks the same, but the stems are very short!

I ended up cutting the long stems to bring indoors and enjoyed photographing them: macro shots with my iPhone 15 Pro Max and

And Canon Powershot SX70 HX high key shots (almost white background) and

Some warm glow shots of a group.

Of course, there other plants active in the yard. Hostas are growing well – both the original clumps and the ones I started this year by dividing some older clumps.

There are lots of dandelions in various stages of development. I tend to let them alone since the bees like the flowers and the roots are deeper than the grass root which helps hold the soil – particularly on slopes.

There are more violets that ever spilling out of flower beds and into the yard. There are some places that I have stopped mowing because the violets are so thick!

The irises I transplanted into the area where the pine tree was cut down last summer are growing vigorously. Maybe one or two will bloom this year although it won’t be great until next year. The lambs ear is growing well and should fill in more around the irises over time. The beautyberry does not have leaves yet but we’re still having some cool days/nights; hopefully it will leaf out in May.

I took some ‘art’ pictures of an iris bud and new rose leaves early in the month.

A lot is growing in the wildflower garden from last year. Some might be weeds…hard to tell until the plants start blooming.

Pokeweed is coming up everywhere. I am going to cut down plants that get above a certain size. I also plan to rake pine cones that are around one of pines toward the fence so that I won’t mow over them (they are a little tough for the lawn mower to cut!).

Overall – a great month in our yard. The rhododendron is full of buds…but not blooming yet…a lot more beauty coming in May.

Road Trip to Dallas – April 2024

/

Last week I made a 2-day road trip down to Dallas to visit with my dad. It’s about 7 hours of driving in each direction. When I left my house in Missouri on the first day it was dark. Just as the horizon was beginning to brighten behind me, I saw a large bird fly over the interstate – higher than my car but not that far in front of me. I wondered if it was a barn owl although I didn’t get a good enoug look other than to realize the bird had a lot of white.

After my first rest stop the sun was up and more birds were moving about. I saw a large one fly across the highway…a little lower than was safe and then just above my car there was another of the same kind. It was a turkey! I was close enough to see the eye glinting.

I saw a great blue heron flying along or over the road twice…and a murmuration of smaller birds that spilt in two over the highway.

The highlight of the drive down was the rest stop on US 75 just after crossing from Oklahoma to Texas. The berm between the highway and the rest stop parking was full of wildflowers!

Closer to the building there were beds of wildflowers…including the Texas state flower: bluebonnets.

I enjoyed trying my new iPhone 15 Pro Max phone to take some macro pictures of some of the flowers.

Heading home the next day, I left the hotel about 6 AM and got to Hagerman National Wildlife Refuge about 20 minutes after sunrise. Unfortunately, it was very cloudy and sprinkling so there was not a lot of bird activity, and the light was not great for photography.

The surprise of the morning came when I saw something on the road in my left peripheral vision as I moved slowly along Hagerman’s wildlife road…..as I turned to see it better I realized it was a hub cap. I got out of the car to see if it belonged to my car…and it did! It was the first time anything like that has happened to me in 55 years of driving! I put the hub cap in the car opting to not try to put it back on until I got home.

I saw two flocks of cattle egrets as I was driving back toward the highway from Hagerman.

As I drove through Oklahoma, I was driving thorough moving cloud shadows. They were moving in the same direction as I was, and I was moving faster than they were!

The drive was very routine until my route direction shifted from north to east. The wind buffeted the car and the big trucks on the interstate were even more impacted. The last 3 hours were exhausting – requiring both hands on the steering wheel and hyper awareness of the vehicles (particularly trucks) around me.

I made it home in a reasonable time but was very tired.

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.

Tax Burden by State – A comparison done by WalletHub that compared the 50 states on 3 types of taxes - property taxes, individual income taxes, and sales and excise taxes - as a share of total personal income in the state.

See a Restored Ancient Roman Helmet—and Two Shiny New Replicas – 2,000-year-old helmet made of silver-gilded iron.

Solar Savings in the US – Looking at the numbers….

Feral Hogs to Be Removed from Congaree National Park – My husband and I visited Congaree in 2008 and I vividly remember the feral hogs. Evidently action is being taken to remove them. They have become a pervasive problem to both the park and surrounding landowners, routinely causing widespread damage to land and water resources both within and outside of the park. Recent observations have shown that they have begun to cause more extensive damage to areas near the Harry Hampton Visitor Center, including areas where synchronous fireflies are active and where restoration of longleaf pine is ongoing.

What four decades of canned salmon reveal about marine food webs - The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Researchers dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms -- a common, tiny marine parasite -- within the flesh. The parasites were killed by the canning process but still visible… counting them is one way to gauge how well a marine ecosystem is doing.

Texas Solar Power Growth Changing the Shape of Daily Electricity Supply in ERCOT – Looking at the changes between 2022 and 2023…easy to see graphically.

Functional capacity in old age is like an ecosystem that may collapse when disrupted - In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning.

Ming Dynasty Tomb Found in China's Xinfu District – Part of excavations before nearby highway construction begins.

I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans - The rate with which we perceive the world is known as our "temporal resolution." Though our visual temporal resolution is quite stable from day to day in general, a post-hoc analysis did suggest that there may be slightly more variation over time within females than within males.

Study Reveals Vast Networks of ‘Ghost Roads’ in Asian Rainforests - An extensive analysis of satellite imagery has uncovered thousands of miles of unmapped roads slicing through Asia’s tropical rainforests - “ghost roads” may be laid down by miners, loggers, poachers, drug traffickers, and land grabbers, often illegally.

Then and Now: Groceries

/

In the 1960s, my mother did the grocery shopping for the family – usually going once a week.  I went with her occasionally but not often. She usually shopped while my sisters and I were in school. Her favorite grocery store was Safeway. I am now shopping at Walmart most of the time since it is the closest grocery store to me and once a week is still my goal. The hours my The Walmart is open from 6AM-11PM, 7 days a week; the hours grocery stores were open in the 1960s was a lot less than that and there were items they couldn’t sell on Sundays if they were open then (‘blue laws’ in Texas).

The carts were similar in design to the larger ones in most stores now although they were all metal (no plastic) and did not have seatbelts for young children. Most grocery stores now  have a few smaller carts along with the larger ones but I usually am buying enough that I get a large cart.

My mother always had a list that accumulated over the week; most of the time she made the additions to the list but as my sisters and I got old enough, we sometimes wrote in items. Now I use the OurGroceries app so that my husband and I can add items to the list from any of our devices and I use my phone when I am in the store rather than a piece of paper.

My mother only bought food at the grocery store…not toiletries or over-the-counter medications; those were purchased at a drug store which also included a pharmacy. I buy many non-groceries during my weekly shopping now; toiletries are frequently on the list, but I sometimes buy clothes or office supplies as well. It’s an advantage of shopping at Walmart rather than a grocery store. We still pick up our prescriptions at a CVS; the pharmacy at Walmart is not open at the time I usually shop (between 7 and 8:30 AM on Friday mornings).

At checkout, a cashier had to enter the price of each item on the register and the strip of paper that my mother was handed at the end only included the prices and the total. She paid with cash or wrote a check. Now I scan my purchases myself, use a credit card to pay for them, and get an itemized list that includes an abbreviated description of each item along with the total.

Mother’s purchases were put in brown paper bags by the cashier. Now the store provides single-use plastic bags; I’ve used my own bags for more than a decade (they are stronger, and I don’t have to take precautions to contain the single-use bags from littering and polluting the environment). I put my items into my bags after I scan them. All the refrigerator items go into an insulated bag and the remaining items are grouped into bags to make unloading easier once I get home (and to make sure bread, chips, and eggs are not damaged in transit).

There was a lot less plastic. Milk came only in cartons (waxed…not plastic coated) and juices and soft drinks came in glass. Canned foods were purchased frequently, and the cans were not lined with plastic. The produce section included mainly seasonal foods along with ones that could be easily stored/transported (like bananas). Broccoli was something we had periodically as a frozen vegetable, and it was packaged in a box rather than a plastic bag.  We enjoyed strawberries seasonally or frozen (in a box); now my husband likes the frozen ones (in a plastic bag) more than he likes fresh ones! Plastic is the dominate packaging now: jugs of milk, bottles of water/soft drinks/juice, bags of frozen veggies and fruit, robustly sealed meats, bags of snacks and fresh vegetables/fruits, jars of peanut butter. Sometimes there is an option to buy in class jars but most of the time there is no choice; the packaging is plastic.

The most common type of bread was white; my mother wanted ‘whole wheat’ and bought Roman Meal when she could find it. I buy Dave’s Sprouted organic bread….avoiding a lot of added chemicals that have been introduced over the years to keep bread from molding or otherwise ‘improving’ it in some way (‘improving’ is in quotes because many breads cross over into the ultra-processed realm with the additions that are quite common today).

Some of the brands are still around: Cambell’s, Nabisco, Kelloggs, Green Giant. I don’t buy them as often as my mother did…only Cambell’s Tomato Soup and Green Giant Niblets Corn for my husband.

There are a lot of products in the grocery store that were not available in the 1960s…most of them ultra-processed and they fill up whole aisles of the grocery store. It requires some willpower to steer clear of those (although it gets easier over time). On the healthier side, it is now easier to find international foods (salsas and tortillas, etc.) and things like boneless chicken breasts…a lot more options when it comes to pasta, sauces in glass jars, greens (kale and arugula were not in grocery stores in the 1960s), grains/seed (quinoa and chia are new…’chia pets’ were not introduced until the later 1970s), and no salt seasonings. There are now targeted foods for special diets; for example, milk that includes Lactaid for those that are lactose intolerant and protein shakes for diabetics or those dieting and concerned about getting adequate protein.

My mother was very conscious of nutritional guidelines; she had taken home economics courses in college. We had some form of protein at every meal along with fruits and vegetables and grains. Sugary items were only for special occasions. There were seasonal fresh foods, but she relied on canned goods more than we do now, particularly during the winter. Both sets of grandparents had big gardens and we enjoyed their bounty whenever we could – supplementing what was purchased at the grocery store; we knew how food was grown and a little of how it was preserved (canned) for later. Now we buy more fresh or frozen fruits and veggies rather than canned because they are readily available during the whole year. I also buy organic as much as I can….something that didn’t exist in the 1960s.

Groceries have changed significantly since the 1960s. Availability of healthy foods is probably better now – although it takes more attention/knowledge to avoid the ultra-processed foods that are often intermingled with the healthy food.

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.

Touching Image of Intergenerational Love Wins Black and White Minimalist Photography Prize – Minimalist…but powerful.

How an English castle became a stork magnet – 30 White Storks from a rescue project in Poland introduced in the rewilded habitat at Knepp Castle in southern England in 2016. At one point, storks even built nests on Knepp Castle itself although they usually build their nests in the crown of huge oak trees. The young storks started migrating in 2019. The colony has grown to about 80 storks…and is the first breeding colony in Britain in 600 years.

Evidence for Domesticated Chickens Dated to 400 B.C. - A study of eggshell fragments unearthed at 12 archaeological sites located along the Silk Road corridor in Central Asia.

Noisy Summer Ahead for U.S. as Dueling Broods of Cicadas Emerge - It is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House. Mating season will last until July.

California’s Live Oaks in Focus - Some centuries old, the oaks are magnificent giants that can grow up to 100 feet tall and are what remains of a forest that once blanketed the region.

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Analyzing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health. Microparticles from car tires, pesticides from farmers' fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach.

Cars & Road Trips Made a Huge Difference in Women’s History – One of the first cars ever built got taken by a woman, without permission, on the world’s first road trip! Bertha Benz wanted her husband’s invention to be seen out in the country so people would buy it, but her husband Karl Benz was being timid about it. So, she took the car out on a road trip with her kids.

Common household chemicals pose new threat to brain health - The new study discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells. Loss of oligodendrocytes underlies multiple sclerosis and other neurological diseases. They identified chemicals that selectively damaged oligodendrocytes belong to two classes: organophosphate flame retardants and quaternary ammonium compounds.

The Soundtrack of Spring on the Platte River – Sandhill cranes staging last month along the Central Platte River in Nebraska. So many birds….lots of sound.

These Are the Most Polluted National Parks – Many national parks are suffering from air pollution and facing threats stemming from human-caused climate change. 98 percent of parks suffer from visible haze pollution, while 96 percent are grappling with ozone pollution that could be harmful to human health. Four of the nation’s parks with the unhealthiest air are in California: Sequoia and Kings Canyon National Park, Joshua Tree National Park, Mojave National Preserve and Yosemite National Park. Another California site, Death Valley National Park, also made the top ten list. 57 percent of national parks are facing at least one threat stemming from climate change that could permanently alter its ecosystems, with many parks grappling with multiple issues at the same time. Invasive species were the most prevalent issue.

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 do terracotta warriors tell us about life in ancient China? – Discovered 50 years ago…they are a snapshot of the soldiers of Qin – the feudal state that unified China, for the first time in 221BC under the country's first emperor Qin Shi Huang – from the soles of their shoes to their candy-colored clothes to the bronze weapons buried with them to their distinct facial features. 2,000 terracotta warriors have been excavated but more are uncovered every year.

This Map Shows Where Planting Trees Would Make Climate Change Worse - Trees draw down carbon dioxide from the atmosphere, helping to keep warming in check. But their dark, green leaves also absorb heat from sunlight. Snow and sand, by virtue of their light color, reflect more sunlight back into space. As such, trees planted in snowy areas or in the desert will absorb more sunlight than their surroundings, which may negate the climate benefits of soaking up carbon dioxide.

These 3,000-Year-Old Treasures Were Forged from Meteoritic Iron - In the 1960s, researchers discovered a trove of Bronze Age treasure in Villena, Spain. New research has revealed that some of them made between 1400 and 1200 B.C.E. were forged from iron from a meteor that struck Earth a million years ago. Who manufactured them and where this material was obtained are still questions that remain to be answered.

Vernal Pools Make Your Garden Sing - It’s not just frogs that are making homes in these little pools of water. Less vocal species like salamanders, dragonflies, fairy shrimp, and even dozens of native plants are there too. Even more species than that can be found simply visiting the pool for a drink or snack, including great blue herons, wood ducks, and box turtles.

Return of Trees to Eastern U.S. Kept Region Cool as Planet Warmed - Over the 20th century, the U.S. warmed by 1.2 degrees F (0.7 degrees C), but across much the East, temperatures dropped by 0.5 degrees F (0.3 degrees C). A new study posits that the restoration of lost forest countered warming, keeping the region cool. Still, the return of trees can only partially account for the drop in temperature. Other possible explanations include the growth of irrigation, a source of water vapor, and the uptick in particulate pollution, which reflects sunlight, thereby cooling the air.

Sweetened drinks linked to atrial fibrillation risk - 20% higher risk of irregular heart rhythm, known as atrial fibrillation, among people who said they drank two liters or more per week (about 67 ounces) of artificially sweetened drinks. The risk was 10% higher among people who said they drank similar amounts of sugar-sweetened beverages.

Measles outbreaks and what parents need to know - Measles can lead to complications such as ear infections, diarrhea, pneumonia, and encephalitis (brain swelling). One to three of every 1,000 children infected with measles dies. More than 97 percent of the people who have had their two shots of the vaccine never get measles.

A new world of 2D material is opening up - 2D materials have shown great potential for an enormous number of applications. You can imagine capturing carbon dioxide or purifying water, for example. Now it's about scaling up the synthesis and doing it in a sustainable way.

In Cleveland, mushrooms digest entire houses: How fungi can be used to clean up pollution - Fungi can eat the noxious waste from abandoned homes. Heavy metals and other toxins are extracted and captured in the mushrooms that grow, while the substrate leftovers, including the mycelium, are compacted and heated to create clean bricks for new construction. The resulting "mycoblocks" have a consistency akin to hardwood and, depending on the specifics of the manufacturing process, have been shown to be significantly stronger than concrete.

Arctic nightlife: Seabird colony bursts with sound at night - Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.

When does a road trip become a commute?

/

The road trips to Carrollton/Dallas TX have been going on for years – increasing in frequency in recent years as my parents got older. Until recently their duration as been for at least a week; from Maryland it was a 2-day road trip in each direction which was reduced to 7 hours once we moved to Missouri. Sometimes I stayed longer – for hospitalizations/recuperation primarily. There were no trips at the beginning of COVID, but they started up again as soon as we were vaccinated. They are almost always on my own and my parents’ house became almost like a second home since I was spending at least 25% of my time there.

Since my mother’s death and the sale of their house, things are changing. I drive down one day and come back on the next – visiting with my dad for a few hours and staying in a hotel overnight. I’ve done it 3 times and am beginning to realize that the road trip feels more like a long commute.

The route is becoming very familiar. I set the navigation system but really don’t need it. The places I stop (usually Loves or Pilot….sometimes Choctaw Travel Centers) are familiar. There was a Stuckeys that I stopped at occasionally, but it was always a bit grungy and I noticed on the last trek that I had closed. My route is not on Interstate for the most part and I am very aware of the speed limits going though towns.

Music helps keep me alert…and variety helps. Apple Music on my phone playing via Bluetooth on the car speakers is the way to go!

There are several assignments I give myself to stay focused on the road and surroundings. Some of my favorites are:

  • Observing birds (particularly hawks in treetops, great blue herons or great egrets flying, soaring vultures, murmurations of smaller birds….hoping to see a bald eagle). It’s depressing to notice hawk or owl roadkill, but it happens.

  • Noticing the trees – particularly in the spring and fall. Recently I have been paying particular attention to red buds which are scattered among the roadside trees….not thrilled about the escaped Bradford Pears (Callery Pears) that are also there.

  • License plates, particularly in Oklahoma, are more varied than in most states because the Oklahoma tribes have their own plates! Most of my observing of plates is during the times I’ve slowed down for a town and there is more traffic.

  • There is plenty of time to plan what I need to do when I get to Dallas…or when I get home. On the way down, I think about topics that might interest my dad and whatever estate actions I need to take. On the way home, I think about blog posts and, this time of year, what I need to do in the yard.

Phone calls generally factor into the time I am in the car – hands free of course. I call my husband to let him know when I will get home, and my daughter usually calls me for a longer chat when she knows I am driving. It helps pass the time.

More focused purpose. I am realizing that the trips have one overwhelming purpose – to see and visit with my dad. It’s a few hours rather than 24/7 for a week like it was before. There is not much time for anything else although brief times out in nature might still happen…although not on every trip.

And that is how my road trips to Texas have become more like a commute.

Dickerson Park Zoo (1)

/

We enjoyed the Dickerson Park Zoo (Springfield MO) on a cool sunny day in late March. My husband and I got a gift membership from my daughter, so we’ll go several times this year. The zoo is always a great opportunity for photography.

The peacocks that roam freely are always photogenic. The birds are very acclimated to people although all the visitors gave them plenty of room too. I only saw one in full display – tail up and expanded; there was no females around, so it wasn’t clear what prompted the display.  The males seemed to be the only ones out during this visit; I wondered if the peahens were sitting on eggs.

The flamingo enclosure is one of my favorites because there is an area where there isn’t a barrier (mesh or fence) between my camera and the birds. I zoomed in on one I thought was sleeping; I liked the arrangement and color variation of the feathers; I discovered when I got home that the bird was evidently awake!

The Trumpeter Swans were living up to their names as the made their way around the pond…very noisy. Beads of water on the swan’s back show how well the feathers keep the swan from feeling wet!

The zoo still has a lot of daffodil/narcissus flowers. Our shifts between warm and cold days (and back again) seems to be prolonging the blooms this year. They are planted around naturalized rivulets.

More pictures from the zoo tomorrow….

Ten Little Celebrations – March 2024

/

Picking 10 little celebrations is only challenging because there are so many of them to choose from! I help myself by only noting one each day, but I realize when I look at the list at the end of the month that there are even more, in retrospect, worthy of celebration. Here are the top 10 for March 2024.

My mother’s life. The phrase ‘celebration of life’ is more like a savoring because there is an overlay of grief that is part of every gathering after a death. I stayed focused on making sure that someone was with my dad for the duration and providing narration of the images in the slideshow for him…varying what I said a bit each time it repeated and realizing that she had a very full 92 years!

Getting the check deposited after the sale of my parents’ house. What a relief to not be carrying around a big check!

Home again. I made multiple short trips to Dallas for various reasons and was always very glad to be home again. Even though the time away is only a couple of days, the stress of driving, my task while in Dallas, and staying in a hotel takes a toll. I don’t really relax until I am at home. Hopefully, when I am only going down to see my dad, it will not be as stressful.

Sequiota Cave Boat tour. What a great tour. I liked the non-commercial nature the tour…seeing the tiny bats roosting.

Springfield Botanical Gardens. Full of spring blooming trees.

Dickerson Park Zoo. My daughter gave us a membership for Christmas, so we’ll be enjoying the zoo often over the next year. I liked the roaming peacocks (and other things too). The post about this visit is coming day after tomorrow.

Feeling better. I got sick with something that caused sinus and throat problems. I tested for COVID for 3 days…and was negative for that. And then I recovered rapidly and I celebrated. Also celebrated that my husband did get whatever it was.

Creating more hosta locations. I divided some of my hosta plants as they first began to come up and was pleased that the new plants adjusted very quickly to their new space. I am looking forward to their lush growth this summer…and will divide more plants next spring!

Burning sticks. I enjoyed the fire in my chiminea after cleaning up the small branches and pine cones around my yard….celebrating with some pictures of the fire!

Butterfly and pollinator seeds planted. I celebrated getting the beds prepared and the seeds planted…right at the mid-March suggested planting deadline.

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.

Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

  • The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

  • At night, the cranes move to the Platte River for safe roosting in the shallow water.

  • Sandhill cranes are the most numerous of the world’s crane species.

  • In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

  • Increase tree percentage in parks and green spaces

  • Provide shade on sites

  • Use plant materials and water instead of hardscape

  • Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.
