18 months in COVID-19 Pandemic

/

18 months into the pandemic and the US is experiencing high rates of delta variant infections. The number of new cases is higher than it was in September 2020 and the number of new deaths is a higher too although not as much as the new cases; the vaccines and early treatments are reducing the number of deaths somewhat. The most people in the hospital and dying are unvaccinated. More schools are opening this fall – mostly with mask mandates. There is a lot of concern for the children under 12 since there is not a vaccine approved for them yet.

On a personal level, I am glad I am fully vaccinated, and that the KF-94 masks protect me as well as others. The availability of higher quality masks is one of the differences from last year when I was still wearing cloth masks (2 of them) that were protection for others – not necessarily for myself. I wear my mask anytime I am not at home indoors (like the grocery store) and outdoors when I am near other people (like at the Farmers Market). We are not eating in restaurants…but getting takeout occasionally. I haven’t done another road trip in the past month.

I am attending training for volunteer gigs coming the fall – ones that are primarily outdoors. Those will start in a few weeks if the local schools manage to avoid major COVID outbreaks that would force them to close. There are some places where it appears the delta variant has already peaked (like Springfield MO) but I’m glad I am not planning another road trip until mid-October when (maybe) the overall infection rate will be lower that it is right now on my route to and from Texas.

I wish I could see an clear end of the pandemic, but it may just be wave after wave of variants…some that the vaccine might not be effective against. I’m glad that masks are effective against respiratory spread in general and have grown accustomed to wearing one.

It is frustrating that COVID is still demanding so much of our attention at a time when we need to focus more on actions to address the larger rolling disasters of climate change.

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.

Wind Energy Accounted for 42% of New US Power in 2020 – And solar was 38% of the new energy. And 8 east coast states have large offshore wind projects in the works in the years ahead. Hurray! It’s a good trend and it looks like the slope of the trend will keep increasing for wind and solar (decrease and go to 0 for new natural gas).

How people respond to wildfire smoke -  Another reason to slip on a mask.

Devastating Rain in Tennessee – A map of the change in soil moisture between August 20 and August 21. The floods on August 21 in Tennessee (area circled on the map) killed at least 22 people. I was surprised that there was an area of Illinois (to the north and a little west of the flash flood circle) where the soil moisture increased even more; perhaps that area floods frequently and the area is managed with flooding in mind.

New analysis reveals Vesuvius Victims’ diverse diets – From analysis of Herculaneum skeletons. Men got more of their protein from seafood. Women ate more meat grown on land, eggs and dairy products.

Eye provide peek at Alzheimer’s disease risk – Amyloid plaques can form in retinas of the eye. Does their presence there provide a visible biomarker for detecting Alzheimer’s risk?

Top 25 birds of the week: Wild Birds! – Bird photography…..challenging and beautiful subjects for our cameras.

Have you seen a weasel lately? – There is a suspicion that weasels are in the decline…but the data is circumstantial. These are not predators that have been widely studied. The post points to a role for citizen scientists!

Dispatches from a world aflame – Reviews of two books about the recent fires…and the relation to climate change.

Preemption of Green Cities in Red States – At a time when we need to get serious about addressing climate change – a drive by some states to keep local governments from taking any action. There is a cognitive dissonance between historically arguing for local control then usurping that control when the state government does not agree with it. I like local control but acknowledge that higher up the governance hierarchy could make sweeping changes easier. Perhaps some of these state governments will redeem themselves by quickly taking strong action toward climate change reduction and mitigation – soon. The top issue for me when I vote these days has become climate change!

Climate Change Is The Greatest Threat To Public Health, Top Medical Journals Warn – Another reason that actions to address climate change must be at the forefront of our thinking about the future. Medicine cannot make up for the injury we are making to ourselves and every living thing on the planet.

Entomologists Eradicated the First Asian Giant ‘Murder’ Hornet Nest of 2021 – Includes a picture of the 9 layers of the nest that was carved into an alder tree’s interior.

Turning thermal energy into electricity – It seems like this type of electricity production would have application beyond the military. Even solar panels produce heat and finding a way to automatically harness that into more electricity would be a good thing.  

Climate Change Producing More “Fire Weather” as Far East as Oklahoma – It’s not just the west coast that has a higher risk for fire as the planet gets hotter.

Aztec Pictograms Are the First Written Records of Earthquakes in the Americas – One of the pictograms matched to a 1507 earthquake that coincided with a solar eclipse!

Food systems: seven priorities to end hunger and protect the planet – A thoughtful commentary re ending hunger and improving diets; de-risking food systems; protecting equality and rights; boosting bioscience; protecting resources; sustaining aquatic foods; and harnessing digital technology.

Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk – There was a similar article about pecans a few days ago. I’m glad I like both walnuts and pecans! However – ½ cup is a lot to eat in one day. Usually ¼ cup is considered a serving.

Top 25 birds of the week: Woodpeckers! – I always enjoy hearing a woodpecker in the forest…and its a special tree to see them in our yard. The piliated, downy, and red-bellied woodpeckers are native to our area.

How to fight microplastic pollution with magnets – Many people filter their drinking water…but the conversation about filtering microplastics is newer. Hopefully filters that are effective and affordable will become the norm. It will take a long time to reduce the microplastic load already in the Earth’s water. We are just not recognizing the damage they are causing.

Americans Moving to Disaster-Prone Areas, Despite Climate Change – I’ve started to think about this more recently so appreciated seeing this post. Taking climate change into account – why would anyone buy property in areas that will be increasingly flood prone or incredibly hot/dry? A house nestled in a forest may look appealing but there are an increasing number of people that have already experienced the hazards of that beauty.

1,800-Year-Old Flower Bouquets Found in Tunnel Beneath Teotihuacán Pyramid – I visited Teotihuacan in the spring of 1966 when my parents took me to Mexico City. It was one of the highlights of the trip. The new discoveries are interesting….and I am thinking about whether I would like to see it again. Maybe in spring of 2026? The article references a site with some great pictures of Teotihuacan – worth a look.

Zooming – August 2021

/

While I was out waiting for the Monarch butterfly to emerge, I took pictures of other insects and plants…using the zoom on my camera while I sat comfortably on a gardening stool on the front walk that borders the flowerbed. There was a black eyed susan with petals in disarray, flies, aphids on a milkweed leaf, and various insects on the mint flowers. It was a good way to fill in the time. Enjoy the slideshow!

These days – I appreciate seeing insects more than ever before. Many times when I expect to see them, there don’t seem to be as many around…or any at all; the stories about the crash of insect populations is observable in the field! It’s one of the manifestations of how humankind is warping the planet. With insects, the impact is direct with the use of pesticides and the herbicides on food/host plants for insects and indirectly through the cumulative effect of more and more greenhouse gases in the atmosphere that impacts the climate overall.

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.

The subtle influence of the moon on Earth’s weather – Tides….and a lot of complex interactions associated with them. High tide flooding will increase as the climate changes for example.

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.

30 years ago – August 1991

/

August 1991 was a stressful month at work for me – several people I depended on took advantage of an early retirement offering from the company and the two projects I was working on were both demanding a lot of time. It might have been one of the highest overtime months of my career after motherhood. Between work and my daughter’s needs, I had very little discretionary time for myself. It was the month I fully appreciated how critical my husband’s support was to enable the peaks of my career.

We had a surprise visit from one of my aunts (with her husband and 2 grandchildren); they only stayed one night but it just added to the overwhelming activity for the month.

We had visited Texas in July and were getting follow up letters in August: my Mother starting her last year of teaching, one sister house hunting and planning to visit in October, another going through similar motherhood experiences with her child the same age as mine, and the sister 8 years younger than me realizing she didn’t know me very well. The documentation I have for the month is largely through those snail mail letters!

My daughter was savoring some activities at home that she had enjoyed for the first time while we were in Texas: dabs of shaving cream to wear around before playing in her pool (a substitute bath) and painting (on paper and herself). She was beginning to use her right hand more although she was not as strongly right-handed as her cousin. She discovered she could make footprints on the deck if she walked with wet feet.

She also remembered music from the Texas visit. Whenever the cassette tape with “Let’s go fly a kite” on it played…she always smiled and clapped when that song played.  

When we went to Wheaton Park we discovered she liked the swings under a large catalpa tree better than the carousel!

It was a time of tension between work and motherhood. The techniques I had for coping were developing - not perfect; over the next few years – I accepted that it was OK to always be developing rather that achieving perfection. But in August 1991, I was pushing for perfection.

I also noted a high ozone day. Looking back, I realize that if there had been action during the 1990s…the climate situation would be better today. I was aware of the greenhouse effect…and that the earth was warming; but in 1991 I thought it was an academic idea, not something that was actionable. Like so many others – I thought it would be very gradual and there would plenty of time for corrective action. So now we are facing an urgent need to pivot --- a challenge to us all. I find myself thinking about what it will be like in 30 years – trying to take actions in my own life to sustain hope for the successful transitions we’ll have to make going forward.

Emerging Monarch

/

I went out each morning after finding the Monarch butterfly chrysalis on the day lily leaf; on the second morning that the chrysalis had turned from pale green to clear – the indication that the butterfly was almost ready to emerge. Since I hadn’t seen any Monarchs in our yard this year…I decided to attempt capture the emerging butterfly with my camera.

I came back 30 minutes later…thought perhaps the chrysalis wall was weakening…that some parts in the middle were beginning to split. I had changed to my bridge camera (Canon Powershot SX70 HS), mounted it on a monopod, and was sitting on a comfortable stool.

30 minutes later it looked like the top – above the horizontal row of gold dots - was beginning to split.

Another 30 minutes and I was out again – zooming in with the camera and thinking, at first, that nothing much had changed. But then I noticed some action on the other side of the chrysalis.

I changed to video since I knew the emergence would happen very quickly. It is not a great video (I need practice with video as much as I do with macro photography!) but I learned a lot from watching it later. The chrysalis did crack open but not exactly in the way I anticipated. What I was seeing at the top of the chrysalis was the abdomen of the insect which was huge! It must contain the fluid that is needed to expand the wings. The papillae on either side of the proboscis moved a lot at the beginning and I wondered if they were somehow involved in the fluid distribution or simply cleaning up the area around the face. See the video here.

After the video of the main event – I went in to let my husband know it had occurred and came back out to finish the event with some photes. Over the next 30 minutes the butterfly’s wings continued to unfurl and expand. At some point the butterfly ejected the extra fluid in its abdomen.

30 minutes later the butterfly finally opened its wings. Note that the abdomen is smaller than when it first emerged and it is probably a female.

What a great way to start the day!

Macro Photography Practice (5)

/

Continuing my practice sessions…

Finding the Monarch chrysalis was the prompt for the fifth practice. There are so few of them these days; very different from the 1990s. I sat on a gardening stool to be comfortable and worked to get magnified views of the golden beads and the top of the chrysalis. The water droplets were just nice ‘extras.’

While I was busy with the chrysalis, a cabbage white sat for a few seconds on a nearby plant. It wasn’t a good angle and the picture is not sharp…but it was the first active insect for my practice session. I’ll be trying for more of these. The trick it to practice enough to be able to focus quickly!

I practiced on a mint flower and a leaf….higher magnification that I’d attempted before.

There was a sticker like weed (one that I pull when I find it) within easy distance of my seat on the stool so I did a series of images – with increasing magnification. It was a more interesting subject than I anticipated!

I tried the same thing with a nearby day lily leaf – without as much success. The colors are somewhat interesting but my focus is off in some of the images…..more practice required.

Previous practice post: 1 and 2 (includes gear); 3 and 4 (includes some indoors images)

Day Lily Leaves

/

In the later part of summer, I always cut the day lily leaves when they start to turn yellow so that they come back with new growth that is fresh and green until the frost. It probably reduces the amount of bulb growth underground but the beds are so dense in the beds that it doesn’t matter. Last year it happened in early August. This year the leaves stayed green longer. Maybe we got more rain or maybe the temperatures were better for the leaves to continue growing – or maybe their season is longer now due to climate change. The two areas we have day lilies are in the front flower beds and around the base of our oak tree.

20210821_072558.jpg

And every year, one of the tools I use is the old hedge trimmers I have from my grandfather.

He gave them to me when I bought my first house in the mid ‘70s; the handles were already mended. They must be over 50 years old and maybe much older! They are a wonderful reminder of him. I like using them more than the electric hedge trimmers because of the good memories that crowd into my mind when I pick them up (and they don’t bother my hands as much as the vibrations from the electric trimmers do). I also think how much things have changed since he was born in 1901…the way we now live on the Earth with a lot more people and technology that is damaging the planet…how we have to make some difficult changes to enable ourselves and future generations the quality of life on Earth that recent past generations experienced.

The area around the base of the oak was trimmed all the way around. When the new leaves come in they will cover over the mess. I noticed one side was lower than the other and realized the deer must have been nibbling there. The bed near the house was another story. I got about half done – avoiding cutting any of the black eyed susans – when I stopped because of a small discovery.

Do you see the Monarch chrysalis on the leaf (near the center of the image)? I was surprised to see it since I hadn’t seen any Monarch butterflies or caterpillars this year in our neighborhood. I’m going to take a daily picture of it until the butterfly emerges.

Tomorrow’s post will include a few macro pictures of the chrysalis so stay tuned!

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.

Nine things you should know about sea horses – The males give birth! Like many creatures right now – they are in trouble from climate change (and overfishing in some parts of the world). Not long ago – I learned that there is a species of seahorse native to the Chesapeake Bay. They live in sea grasses and estuaries…habitats that are in trouble.

Electric cars and batteries: how will the world produce enough? – One of the important steps that needs to ramp up as batteries (and solar cells) reach end of life – is recycling. We need to think about closed loops for the resources required to manufacture future renewables!

New analysis of landmark scurvy study leads to update on vitamin C needs – An example of the research behind how those ‘daily requirements’ of vitamins and minerals were developed. I wonder if more of the values need to go through a validation…how many would change just as the vitamin C requirement did.

Top 10 Grassland Species Across the Globe – The ones we have in the US are Long-billed Curlew, Black-footed Ferret, Pronghorn, Swift Fox, and American Bison.

The multi-billion dollar giants that are melting away – Glaciers. When they are gone…many parts of the world will be drier places. This article is primarily about central Asia…but the situation in South America is similar.

Loss of biodiversity in streams threatens vital biological process – Fungi and bacteria can’t do the decomposition job alone…the aquatic insects (often larvae) and crustaceans are needed too. And the populations and diversity of those organisms in our streams is declining.

Top 25 birds of the week: plumage! – Bird photographs…always colorful and interesting.

Gender revolutions in who holds the purse strings – The study was done in Britain…I wonder if similar (or different) changes are happening elsewhere in the world.

‘Polluter pays’ policy could speed up emission reductions and removal of atmospheric CO2 – A change that could speed up the transition we need to make…if we can somehow overcome the lobbying for the status quo trajectory.

Photography In The National Parks: Fun Fact Photography – This is a kind of photography you can do in lots of places. A little curiosity and a camera…some web searches…a neat cycle of learning/art that can turn again and again.
