Ten Little Celebrations – August 2024

The heat of summer is still with us…but there are signs of fall too. Lots to celebrate in August.

Road trip adventures that didn’t become problems. In the first hour of my road trip to Dallas I saw a skunk and an overturned semi-truck. The skunk abled away from the road (i.e. did not become roadkill) and the semi was on the oposite side of the highway!

Finding puzzles. Keeping the supply of puzzles coming for my dad at his assisted living home is a little more challenging since he requires ones with 500 or fewer pieces…and they can’t be small pieces. I was celebrated a couple for a reasonable price and the used book/puzzles sale from Friends of the Library is coming up in a few days where I should be able to get a good supply for $2 each.

A cooler than expected morning in Dallas. My dad likes to take walks in the neighborhood where he lives so I celebrated the morning when I was there was cool enough for the activity (it didn’t start raining until a couple of hours later when I was starting the drive back to Missouri).

Getting the whole yard mowed. I am celebrating that my stamina has improved enough that I can mow the whole yard on one day (my husband made it a little easier by buying an extra battery so I’m more confident of having enough power for the mower even if the grass is a little wet).

A rainy day. It’s been a drier August than usual. I celebrated when I heard it raining in the early morning hours.

Starting the stepping stone path in the new garden area. The narrow grassy area between a pine tree and our flower beds that I am converting to other plants is progressing well this summer. It is currently a compost area for grass clippings, pine needles, and leaves. The hostas that I planted last spring in the area are doing well. I celebrated the milestone of putting done the first two stepping stones that will lead from the patio to the yard through the area.

No tax day for school supplies/clothes. Both my husband and I intentionally made some purchases on Missouri’s no tax weekend for school supplies/clothes…celebrating the annual starting of a new school year. He got 2 pair of jeans and I got some packs of card stock: black and bright colors.

Registering/starting a class at the university. I am celebrating being back in a university classroom after more than 40 years. It feels good!

Multiple types of fungus on a stump in a neighbor’s yard. The stump is deterioating rapidly now. I’m celebrating that there are interesting fungi doing the work.

The Paris Olympics. Celebrating the efforts and sportsmanship of the athletics…seeing their dedication and joy.

Gleanings of the Week Ending July 20, 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.

Why US schools need to shake up the way they teach physics - As the economy becomes more tech-centered, understanding physics is critical. Yet the number of Americans with a solid grasp of physics is dwindling. Learning physics can better prepare you for a role as an aerospace engineer, software developer or environmental scientist, to name just a few. Shifting the way physics is taught so that students see how physics influences their daily lives with examples from sports, extreme weather or baking and cooking rather than rote memorization of formulas with examples from history would increase the number of students mastering physics and prepare them for the future…which is what education should do.

The Smithsonian Acquires the Earliest Known Photograph of an American First Lady – A daguerreotype of Dolley Madison from 1846 when she was 81.

The Hunt: What Happened to the Great Sphinx’s Nose? – The nose was gone well before Napoleon’s time.

NASA Returns to the Beach: Assateague on the Move – The changes in the barrier islands between 1985 and 2019 shown in images from NASA satellites.

The State of Electric School Bus Adoption in the US – Every U.S. state, except Wyoming, has electric school bus commitments. I hope the adoption has the momentum to continue for the health of child and the environment! As of December 2023, 3,700 electric school buses had already been delivered and 4,800 were awarded/ordered.

Huge firework displays will mark 4 July in the US, but the nation's air quality will suffer - Fireworks generate large amounts of smoke, which can have a visibly negative impact on air quality, but they also release other pollutants that are harder to see. In some areas, the concentration of fine particulate pollution known as PM2.5 can be between 1.5 and 10 times higher than normal on the night of 4 July and the following day. These fine soot particles have been linked to a range of health problems including asthma, heart disease and low birth weight. Another negative for fireworks: One analysis of wildfires on federal land in the US over a 37-year period from 1980 found that 11,294 of nearly 600,000 fires over that period could be attributed to fireworks. Two thirds of these occurred in the two-week period around 4 July. There are concerns that perchlorate (used as a propellent in fireworks) contamination can find its way into drinking water, where high levels of perchlorate can interfere with human thyroid function. --- I hope to see more drone shows available in the coming years.

Weaker Ocean Circulation Could Worsen Warming – A new modeling study finds that slowing currents could disrupt the upwelling of nutrients from the deep ocean to the surface, starving the phytoplankton that absorb carbon. The result is that, not only would the ocean absorb less carbon dioxide from the atmosphere, it would also unleash more carbon dioxide from its depths, leading to further warming.

See Ten Awe-Inspiring Images from the Astronomy Photographer of the Year Contest – Beautiful images. My favorite is the solar prominence image.

Proteins and fats can drive insulin production for some, paving way for tailored nutrition - Production of the insulin is much more dynamic and individualized than previously thought. A subset of the population appears to be hyper-responsive to fatty foods. As a next step, the researchers hope to expand their work into clinical studies that would test insulin responsiveness to carbohydrates, proteins, and fats in a real-world setting, and to begin developing personalized nutrition approaches based on the findings.

Clever pupils don't need to attend academically selective schools to thrive – A study from Australia that followed students for 11 years. At ages 19 and 25 there was little difference between the educational and employment outcomes of children who attended selective schools versus non-selective schools. For example, the study found that while 81% of selective school students went on to secure a job or university place at 19 compared to 77.6% of pupils from non-selective schools, this difference disappeared when the students were matched on key characteristics, including socioeconomic background, gender, and geographical location.

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.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

Sales Tax Holiday

I took advantage of the sales tax holiday on school supplies in Missouri to buy supplies for Zentangle creation: neon card stock and pens. I cut one page of each of the cardstock colors into 3.5-inch squares to use immediately…and am enjoying one of the black Sharpie gel pens.

New supplies are still a treat – just as they were over 60 years ago when I was in elementary school. The list of supplies was not published in advance by the schools so there was a line to get into the store and pick up things once we had it. My mother always included us in the shopping…if there was a decision on color/style – we got to make it! What made the experience so memorable? Maybe it was the crowd. I can remember savoring the new supplies too – the pristine crayons, the packages of notebook paper, pencils to sharpen, a fabric covered looseleaf notebook.

I don’t think there were sales tax holidays 60 years ago. Perhaps they are what causes a crowd in the school supply area now since the supply lists are published online or available printed in the stores. When I was in the store there was a mother with two children shopping for supplies…it was before 8 AM on the first of day of the 3-day holiday. The store had organized the school supply area for a crowd…anticipating lots of shoppers to come. I was glad to make my purchases early.

90 Years

Both of my parents are 90 years old this year. I’ve been thinking about the events of their lives and what has happened in the world during their lifetimes.

Their lives began during the Great Depression. They were both born at home; both families were living in rural Oklahoma and grew most of their own food. They were too young to fully realize the stress around the country…secure with their family and small rural community.

Their school memories are from the 1940s --- the World War II era. Their fathers were too old to go to war so the impact of the war on their families was indirect…primarily the rationing programs. Both went to schools where there was only a small cohort at each grade level. Later in their lives they attended high school reunions occassionally – keeping in touch with that small group that had mostly scattered across the country.

They were in college in the early 1950s – the boom years with the GI Bill funding returning veterans and college being encouraged for those just graduating from high school. My parents were ‘first generation’ to college for their families. They married, left the farm, and had 3 of their 4 children during the decade. My dad’s career stayed related to agriculture initially – at first requiring a lot of traveling and then into management of grain storage.

By the 1960s, they were in Texas living in a small city…children in public schools, living in an air-conditioned house (an important thing in the Texas summer). The big health improvement was the availability of the polio vaccine (we all got the vaccine via sugar cubes at school) and the waning of smallpox around the world even though we were still required to get updated vaccines when we traveled to Mexico.  In the mid-60s my mother returned to college for a degree in education…a career she started in the 1970s. My dad’s parents moved from Oklahoma to the same small city in Texas.

In the early 1970s, they moved to a suburb of a big city. They bought a house that accommodated the whole family, including my dad’s parents. My dad had transitioned completely from an agriculture related career to financial management and planning. My mother was teaching. All 4 of their daughters graduated from high school and went to Texas colleges (the last one just starting at the end of the decade). One daughter got married. My parents’ fathers died during the decade. Somehow everyone managed to stay ahead of inflation and pay mortgages that were high interest compared to today.

The 1980s were a very busy decade with careers of the whole family in high gear. My father was coming adept at digital spreadsheets…my mother was focused on reading for students in upper elementary and middle school. The youngest daughter graduated from college. One daughter (me) moved halfway across the country to the east coast and two others got married. My maternal grandmother died. Toward the end of the decade, the first two grandchildren were born.

In the 1990’s, my parents retired from their careers; they travelled and took care of grandchildren and helped with home maintenance (a total of 5 houses in the family!). Three more grandchildren were born, and the older ones started school.

Similar activities continued in the 2000s changing as the grandchildren got older…the oldest ones starting college.

In the 2010s, travel and engagement with family continued in a similar way for the first part of the decade; by the middle of the decade someone else was doing the driving on road trips and they stopped driving completely by the end of the decade. My paternal grandmother died; she had been living in the same house with my parents since the 1970s. Health challenges began to emerge for both parents…intermittent at first and then slowing them down in the last years of the decade. They both benefited from cataract surgery. Other surgeries and injuries required more recovery time…and sometimes recovery was not complete.

The last road trip was for Thanksgiving in 2019…to be with a grandchild. Not long afterward the COVID-19 pandemic locked down travel and they discovered the comfort of ‘stay at home as much as possible.’ Recently they have transitioned to primary care practice that comes to their home for checkups, blood work and most other health needs. Their children and grandchildren come to them now. If they leave their home, it is a very special event. Four of their five grandchildren have college degrees – one has an MD…another a PhD. There aren’t any great-grandchildren – yet.

So many changes have occurred since they were born. Electricity and indoor plumbing were just beginning to be available on farms when they were born. They bought their first air-conditioned home in the early 1960s. Computers came along in the 1980s.

And now – my sisters and I are thankful they are still with us – still enjoying living independently in their home with support from the family, neighbors, doctors, and house cleaners – getting close to celebrating 70 years of married life.

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.

Roman noblewoman’s tomb reveals secrets of ancient concrete resilience – This research has application to the future: transitioning to Roman-like concrete could reduce the energy emissions of concrete production and installation by 85%...and improve the longevity of concrete by orders of magnitude.

How to bring more clean energy into our homes – It’s hard to know what to do that will make the most difference in decarbonization. Electrification is good…as long as the energy used to create the electricity is renewable. This article is explaining one attempt to make it simpler…but it doesn’t seem like it goes far enough.

Does the world need more sharks? – Evidently when sharks decline, herbivores increase and seagrass declines….resulting in less carbon sequestration in sea vegetation. So – more sharks would improve our climate change situation!

The incredible opportunity of community schoolyards – Transforming paved public schoolyard by adding trees, gardens and stormwater management systems and opening them to the public after hours….what’s not to like? It is good for children and the community…and reduces the heat island around the school.

Recycled concrete and CO2 from the air are made into a new building material – Potentially another way to reduce the energy and emissions to produce concrete…but there is still a challenge to make it strong enough for all the current places we use concrete - to make calcium carbonate concrete viable in the future.

10 Writing Awards for Cool Green Science – Some of the 10 have probably be in my gleanings before…but they are worth looking at again.

We need to talk about your gas stove, your health and climate change – 35 years ago, I thought gas stoves were wonderful….but I haven’t had one since 1986, and I won’t buy a house in the future with one (or I will replace it immediately). My current house does have a gas hot water heater and furnace…but I plan to jettison those too. And I don’t want a gas fireplace either!

Clean air matters for a healthy brain – I check the Air Quality Index on Weather.com and there are too many days that the PMI2.5 level is ‘yellow’ where I live now in Maryland. I try to not spend a lot of time outdoors on those days.  It’s another something to think about when/if I move out of the area.

The American Bumblebee Has Vanished From Eight States – The 8 states are: Maine, Rhode Island, New Hampshire, Vermont, Idaho, North Dakota, Wyoming, and Oregon. That doesn’t mean other places are much better. They have declined 99% in New York; 50% in the Midwest and Southeast.

Large scale solar parks cool surrounding land – The observation is interesting. I wonder if the solar parks that I’ve seen frequently around airports in the US are large enough to make up for the heat island effect of all the concrete and asphalt surfaces of the airports.

Zentangle® – November 2020

30 Days in November…such a challenge to pick just 30 from all the tiles I worked on in November! I am striving to do all the layers before I put the tile in the collection for the month….but have a pile of tiles I’ve made over the past few years that I took out from under the plastic tablecloth on the breakfast table when I put out the Christmas cards; I am still coloring and highlighting those old tiles….savoring them again.

There are 9 rectangular tiles (made from the separators in the cat food boxes). My favorite is the first one….reminiscent of fall bouquets.

I didn’t take enough materials to keep me busy during the NCIS commercials….and used the cardboard backing of a pad of paper for a Zentangle tile – an irregular size. It reminds me of coiled snakes – or maybe pangolins.

Another unusual shape for the month – triangular tiles. I didn’t quite get the 6 lined up perfectly for the scan but it was fun to make each gingko leaf tile….and then put them all together. I’ll be doing more of experiments…seeing how they look singularly and together.

The time I spend making Zentangle tiles is enjoyable and rewarding. I am often pleasantly surprised by what I create by the time I finish. I never thought of myself as an artistic person, but maybe that was an assumption I made based on experiences in elementary school ‘art’ classes. Somehow the things we did in art class were not what I wanted to do!
