Gleanings of the Week Ending February 25, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The ancient diseases that plagued dinosaurs – Interdisciplinary teams are re-looking at dinosaur bones and comparing anomalies to diseases visible in modern bones….finding examples of dinosaurs with malignant bone cancer, septic arthritis, and airsacculitis. And it seems that there is a lot more to discover with the technologies now available to look at the fossils more closely and collaborating with vets (particularly vets that work with birds and reptiles).

A worthless life and the worthy death: euthanasia through the ages – The post is written from an Australian perspective and about Caitlin Mahar’s book: The Good Death Through Time. The topic is a thought provoking one….made more interesting with an overlay of history.  I wondered how much the growth of medical interventions has changed the way we envision ‘worthy death’ or is the phrase ‘death with dignity’ a better description now.

Residential solar advantages – 5 top benefits – This is something my husband and I plan to do…solar-plus-storage is our 1st choice. Residential solar also has advantages beyond the home itself: it can power your transportation home too!

Fructose could drive Alzheimer’s disease – More research is needed…but it is interesting that the fructose consumption has gone up in the US (in 1977-1978 it was 37 g/day….in a 2008 study, it was 54.7 g/day). Maybe reducing the risk for Alzheimer’s is another reason to eliminate ultra-processed foods that typically contain a lot of fructose from our diet.

High-paying jobs that don't need a college degree? Thousands of them are sitting empty – Making a career in the trades….and there is a lot of work available.

Why methane surged in 2020 – Interesting findings and how they were developed. The two main reasons: 1) heightened emissions from wetlands because of unusually high temperatures and rainfall and 2) decline in NOx due to COVID-19 lockdowns which broke the chemical reaction in the atmosphere that produces hydroxyl (OH) that serves to remove methane from the atmosphere.

Why aren’t energy flows diagrams used more to inform decarbonization? – Yes! These are easier to understand than a lot of other graphics. The ‘heating the UK with heat pumps or green hydrogen’ diagram caused a ‘learned something new’ moment for me!

Will we ever be able to predict earthquakes? – The answer might be ‘no’ – but there are still a lot of people trying. We can’t rely on predicting them to reduce the destruction in infrastructure and lives. Enforced building codes would reduce destruction and save lives since we already know the areas of high risk for earthquakes. It will be interesting to see an analysis of what the damage from the recent Turkey/Syria earthquake would have been if building codes would have been enforced (the ones that Turkey evidently instituted after the previous earthquake…and also if the ‘best in world’ standards has been enforced).

15th-Century Spices Identified in Royal Shipwreck – Analysis of plants from a 1495 shipwreck in the Baltic Sea off the coast of Sweden: nutmeg, cloves, mustard, dill, saffron, ginger, peppercorns, almonds, blackberries, raspberries, grapes and flax. The findings provide insight on cuisine and trade of the era.

Did you know pronghorns shed their horns? – No…but it a good piece of trivia. I remember seeing pronghorns in New Mexico – racing our vehicle during a guided tour of Sevilleta National Wildlife Refuge.

Ceramics of Masayuki Imai

Like many other museums, The Phillips Library at the Peabody Essex Museum has contributed many volumes to Internet Archive. This exhibit book from 1985 is just one example. Books made to sell in museum gift shops during an exhibit quickly go out of print so being able to browse them digitally is the best way to savor an exhibit whose contents has long scattered.

Masayuki Imai ceramic art 1985 : Peabody Museum of Salem, 21 March-21 May, 1985

I chose 3 images from the book as sample images for their shapes and subjects. I like all things botanical and there were a lot of plants featured in Imai’s work; there probably are not many pots that feature floating pitcher plants like his! Cranes might be a more popular decoration…but the shape of the pot was unusual. The color of the 3rd pot was different than the majority of the pots, making it stand out.

The book includes a short biography of the artist. I did a search but couldn’t find an updated one.

Edamame Pods

Edamame pods have become my favorite light meal/snack. I usually look for shelled edamame for stir fries but recently discovered snack-sized packages of frozen soybeans in pods that are intended to be microwaved 2.5 minutes in the package…then eaten. They are unseasoned. I like them plain but variety could be added by sprinkling with your favorite no salt seasoning. They have 9 grams of protein…90 calories…along with fiber, essential fatty acids and isoflavones….probably one of the healthiest snacks around.

My daughter had introduced me to soybeans in pods served as an appetizer at a restaurant while we were in Canada. The learning curve to get the beans out of the pod neatly was an adventure…but didn’t take long. In restaurants they are often served with salt crystals. I’m glad I noticed the packages at my grocery store so I can include them more frequently in my diet.

The pods are left after the snack. They are not edible. Another edamame pod adventure: some macro photography (with my phone – a Samsung Galaxy S10e). The pods retain the bumps from where the beans were….and begin to curl as they dry. The inside has a lighter layer that looks like padding for the bean. There are also bristles and tiny dark channels on the outer part of the pod.

Now - I’ve collected enough pods over several days. I am putting them in my small compost pile.

A Photography Course

My husband purchased Matt Kloskowski’s Inside the Composition course and we are working our way through the 21 modules.

I’ve done 6 modules so far. Each of them had a short lecture then an assignment…encouraging students to apply the concepts in their own landscape photography. Review and critique of my own photos has been enlightening.

The course has already helped me recognize some shortcomings in my photography –

I tend to like my macro compositions more than landscapes and one of the reasons is that I almost always have too much sky in my landscapes. Sometimes cropping can improve it…although I will try to do better when I am in the field from now on. A good example is this sunset I took back in December…the colors were outstanding…but there is way too much sky. I cropped part of the sky but maybe I should have cut some of the dark foreground too. The result is an odd shaped image but the composition is improved.

Some of my photography is almost like note taking…documentation rather than art: taking a picture to later use for identification of a bird or insect…or taking pictures of signage to read later (or act as a caption to other photos. But the rest of my pictures should be more than documentation. I need to improve my composition on those pictures even if I think about then as documentation of the place. My macro pictures generally composed better than my landscapes!

I tend to like birds moving left to right through my image – even though this breaks the ‘right third’ rule. I always make the assumption and a bird will be moving; we read left to right and our eyes tend to be trained for that direction. Inanimate objects tend to be better place on the right third but software easily flips the image if I forget (see sun yard ornament below).

I should learn to consistently turn my phone when I am taking landscapes. The sunrise picture with half the image a dark band is a good example. Again – cropping can help but it would be better if I’d learn get the composition right when I take the picture!

One of the only landscape pictures I’ve taken recently that I like, turns out to demonstrate some composition concepts. It’s a sunrise pictures but the large diagonals of the silhouetted tree branches in the foreground lead the eye into the colorful sky rather than just having large expanse of colored sky. The second layer of tree silhouettes adds more complexity and the recognition that it is a winter sunrise.

I’m looking forward to the modules still to come….

Gleanings of the Week Ending February 18, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

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

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

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

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

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

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

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

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

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

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

W. Westhoven – Engineer Artist

Six South African Scenes and verse  was published the year Wilhelm Westhoven died (1925) and contained 6 of his paintings. I selected two of the paintings for this post…encourage looking at the book on Internet Archive to see the other 4!

According to a brief biography on Artefacts, he was born in German in 1845, wrote a paper about the Forth Bridge in Scotland (a cantilever railway bridge), and emigrated to the Cape Colony in 1892 where he was an engineer in the Department of Public Works until he retired in 1904. After reading the biography…I checked to see if the paper Forth bridge was available on Internet Archive….and am looking forward to browsing through its illustrations (here).

Coursera Again – Neuroanatomy

The beginning of Coursera coincided with the beginning of the post-career portion of my life a decade ago. It burst on the scene offering auditing of online courses for free (a small fee was charged for the testing and projects for credit). I was like a “kid in a candy store”…so many topics of interest that I never had time for during my undergraduate/graduate years….and some topics that didn’t exist until more recently! I audited a flurry of courses in the first few years then settled into an occasional course – usually in the wintertime when I spend more time indoors; there was an uptick during the COVID-19 pandemic but not to the levels of the first few years.  

I recently looked at my records and discovered I have audited 74 courses! The topics are varied: art, anatomy, nutrition, history, meditation, education, entomology, exoplanets, poetry, psychology, design, and architecture! The nutrition course was one of the early ones…and is where I learned about the Cronometer site that I am still using to track what I eat so that can take off a few pounds.

This month I completed a Neuroanatomy course from the University of Michigan. It is a 7-week course; I completed 3 weeks before I went to Carrollton TX in late January and completed the other 4 after I got back. I did my usual notetaking as I made my way through the material – trying to learn the vocabulary and the anatomical structures. Now I find I want to learn more about neurobiology!

This course pointed me to a new-to-me source of reference books: PDF Drive. Just look at the list of books available for Neuroanatomy! There are lots of other topics as well. I am getting the “kid in a candy store” feeling all over again!

Gleanings of the Week Ending February 11, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Why the world feels so unstable right now – Intermittent instability of nonlinear systems of nature and global society –weather and climate, the economy, a pandemic, a war. We attempt to model nonlinear systems to predict these intermittent instabilities…but it is hard. Right now there seem to be significant nonlinear systems interacting: weather/climate + diseases (COVID-19 and bird flu (US)) + inflation + Russia’s invasion of Ukraine.

Completing The Electrical Circuit at Kilauea in Hawai'i Volcanoes National Park – The technique to get a detailed ‘CAT scan’ of the volcano…..mapping locations of subsurface magma in 3D.

Ex-cell-ent Clouds off Chile’s Coast – Open and closed-cell marine stratocumulus clouds photographed by Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. Learning more about these clouds….contributing to better weather prediction and improving the accuracy of climate models.

The Surprising Substances Ancient Egyptians Used to Mummify the Dead – Evidently some of the substances the embalmers were using came from Southeast Asia. Perhaps embalming instigated early global trade.

Algae robots transport antibiotics to infected tissues (infographic) – Researchers inserted the modified algae into mouse windpipes…they spread into the lung tissue and killed pathogenic bacteria!

Hundreds of Frank Lloyd Wright’s Designs were never built. Here’s what they might have looked like. – Computer generated models from David Romero.

5 expert tips to protect yourself from online misinformation – We all need tools to help us distinguish information from misinformation.

Montessori: The world’s most influential school? – I sought out a Montessori pre-K and K for my daughter about 30 years ago…and it fit her needs. I have no way of analyzing how closely the school adhered to classical Montessori ideals.

An action plan to prevent Alzheimer’s disease – Defining what 2nd generation memory clinics should include.

Gallup: Fewer than half of Americans believe US healthcare is good enough – Not surprising really – it’s expensive and we are all getting more skeptical that the system is as effective as it should be for what it costs. Evidently the people in my age group (over 55) were generally more satisfied with their health care than other age groups; people old enough to qualify for Medicare may not be as anxious about costs but I was surprised that I am in the minority in thinking US healthcare is ‘subpar’ rather than ‘excellent’ or ‘good’ based on the effectiveness issue and the structure of the system overall.

Maria Martinez (potter) in 1925

The first picture in Carl E. Guthe’s  Pueblo Pottery Making - a study at the village of San Ildefonso published in 1925 is one of Maria Montoya Martinez that is widely used elsewhere (including in the Wikipedia entry for her). 1925 was before she started making her black ware pottery that survives in many museums. I recognized her name when I first started browsing the book; it was one of those times I appreciated Wikipedia and Google search to learn more about her before I continued browsing. I celebrated finding Guthe’s books on Internet Archive and the myriad pictures that documented the situation in 1925…the state of the art then, before she was producing black ware pottery.

1925 was during the time when much of the culture of the Pueblos was fading….the challenges of people trying to survive in the world. Fortunately, Maria learned pottery skills from her aunt… a “learning by seeing” beginning in her pre-teens. She, with the collaboration of her family members, continued to experiment and produce pottery throughout her long life (she lived until 1980) and taught others the same way she had learned. She helped establish pottery of the Southwest as an art form we recognize today.

Surprisingly, Guthe’s biography (archived from the University of Michigan Museum of Anthropological Archaeology) does not mention this book at all. His work establishing collections and institutions overshadows this book!

A Patient Perspective of Medical Care in the US

Part of the aftermath of making a long distance move is establishing new doctors. I’ve completed the process at this point – 8 months after the move. It’s been a learning experience. I started out with the intention to find a primary care physician and specialists in the same system so that I would only have one portal for all my medical information – unlike my legacy situation that involved at least 4 different portals. The portal for my new doctors is well organized and has become the primary way I get results and send questions/messages to my doctors. In general, the lab work is done very quickly and posted on the portal; I see it about the same time that the doctor sees it. The system of doctors – specialists – labs – hospital also includes several urgent care facilities that I appreciate; their availability can help avoid a busy ER; I’ve already used an Urgent Care facility prior to my first appointment with my new primary care doctor when I got a very painful bite that looked infected. On the downside -

  • Vision and dental care are not general part of ‘medical care’ from an insurance perspective or systems with MDs; vision and dental are still separate. The initial dental practice I selected wanted to do very different (and expensive) kinds of cleaning for my teeth and I’ve opted to go to a new one that is more like the dental practices I’ve used in the past. It’s hard to know how to evaluate dental recommendations since they are outside of the primary medical system. I like the vision care practice I chose but may have similar misgivings as I get closer to needing cataract surgery.

  • The various specialist doctors and non-blood labs/radiology are in separate buildings; they are relatively close together, but I am careful to record the building address  in my appointment calendar; it’s a high traffic area and it could be challenging to get to the appointment on time if I went to the wrong building first.

Thinking about the big picture of medical care in the US - It is not achieving ‘best in world’ results based on healthy lifespan stats. Why is that?

  • Insurance is expensive and confusing. I’ve had health insurance since the late 1970s and the trend has been increasing cost and complexity over the duration. Checking that doctors are in-network and drugs are ones that are on the formulary is a required skill to get insurance to cover costs….and even then, sometimes surprise charges occur. What happens when your doctor prescribes a drug that is not on the insurance company’s formulary? I am very aware that I have been fortunate to always be insured….understand that the cost of good medical insurance is prohibitive to many and that often means not getting medical care until there is a health crisis…and going to an emergency room.

  • Cultural reluctance/aversion to embrace public health measures. Over the past decade, there has been increased resistance to public health measures (for example, not getting vaccinations for children, older adults declining vaccines, flying when sick (coughing, sneezing),  and aggressively against mask wearing at any time) and demands on health professionals for treatment that is not appropriate for their condition (for example, demanding an antibiotic for a viral infection or are an ineffective drug for COVID or a drug advertised on television that is for a condition the patient does not have). I am mentioning the demands for inappropriate treatment under public health because it impacts the costs for medical care overall, increases resistance of microbes to antibiotics making them less effective when they are needed, and makes the workplace for doctors/nurses more stressful (and some decide to leave the profession resulting in shortages of skilled personnel).

  • Dominate lifestyle. We live in a world of fast food and ultra-processed foods…people are more sedentary because of their jobs or the type of entertainment they choose. It is harder to “eat healthy” now that when I was growing up and as a young adult. Many people in the country are obese and/or in poor physical condition. However – there are a lot healthier foods available now if we educate ourselves. For example – kale was not something I ate as child, now it is my ‘super green’; other foods that I’ve only know in the past 20 or so years include: pomegranates, edamame, beet greens, red cabbage, butternut squash, ground turkey. There are also a lot of ways to measure physical activity…and some have leveraged those metrics to become more physically fit. Still – healthy lifestyles are not as prevalent now. The bump in life expectancy that was achieved after many people managed to stop (or not start) smoking is being eroded.

  • Aggressive intervention with drugs. The medical system tends to treat with drugs rather than recommending lifestyle changes. Part of this skew is the way doctors are trained (often nutrition is not included in their education) and part is probably based on their experience that most patients will not follow through and make a change. If a drug can change the measure the doctor is seeing (like blood pressure or cholesterol levels), then the doctor tends to immediately medicate. Any unwanted side effects from the drugs are resolved through changing to a different drug or adding a drug to reduce the side effect or telling the patient that the benefit of the drug is greater than the impact of the side effect. But – if people can change their lifestyle, they are probably addressing the root cause of the problem rather than artificially doing something that changes the measure but leaves what is causing the problem the same. Long term maybe we’ll know if the drugs really do very much for increasing healthy lifespan.

  • Specialists with blinders to anything outside their specialty. The notion that a primary care physician can integrate care is overly optimistic.

    • Many times, the specialists are proceeding with their focus; if treatment is meeting the measures they want, side effects or over medication are not a priority for them.  For example – an endocrinologist adjusting medication to get the levels of hormones to a precise level is often unconcerned or dismissive of a patient reporting heart palpitations, hot flashes, and eyebrows falling out.

    • Emergency room doctors are focused on resolving the primary cause of the emergency visit and sending the patient home as soon as possible; this leads to quick fixes that often do not prevent the same issue occurring repeatedly. A good example is cellulitis in older patients; the ER gives them antibiotics and they go home…often returning with cellulitis again in a month or so. If the ER is not overwhelmed and there is an alert attending in the ER or in the hospital, more proactive measures can be taken…perhaps re-evaluating the dosage levels and complexity of existing medications, adding a prophylactic antibiotic, etc. that can prevent rapidly recurring ER visits for cellulitis.

  • Lack of trust. Patients believe doctors may have alternative incentives than patient health when recommending treatment/drugs and doctors believing patients may not be doing as they say and/or taking meds as prescribed. Not sure how this can be bridged other than encouraging more transparency on both sides.

The bottom line – I want to believe that I am proactively maintaining my health and being a knowledgeable patient that asks relevant questions to understand my doctors’ logic….thus making the best of the medical care available…but there are certainly times that I have some doubts. So far, I have been able to resolve those doubts and am satisfied that I am on a healthy path. However - I am increasingly concerned about individuals with fewer financial resources, less healthy or not as knowledgeable. The trend is toward more challenges within the US healthcare system!

Gleanings of the Week Ending February 4, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Milk packaging influences its flavor – Light blocking containers are best….and plastic/glass is better than paperboard. So why aren’t paperboard cartons being phased out (they are also harder to recycle than plastic milk cartons).

Clean Energy Saw as Much Investment as Fossil Fuels for the First Time in 2022 – Good! And hopefully this will continue to be the case…and we don’t allow any fossil fuels to be counted as ‘clean.’

What Secrets Lie Beneath This 17th-Century French Aristocrat’s Smile? – Decaying teeth and an ivory prosthesis (in front) held in place with gold wire….and a woman kept her smile and place in society.

A curious Colorado bear strikes a pose for 400 selfies on a wildlife camera – A bear that noticed the camera!

Leprosy: the ancient disease scientists can’t solve – There is treatment…but diagnosis is complicated and there is no cure. And we still don’t know how it is transmitted.

Researchers find rare 17-pound meteorite in Antarctic ice – A team spent a week and half in the Antarctic summer (14 degrees Fahrenheit…so still very cold) sleeping in tents and riding snowmobiles to search for meteorites. They found small ones….and a big one!

New mosquito repellents that work better than DEET – Maybe the next generation mosquito repellent?

In 2021, 20% of electricity in the US was generated from renewable sources – And wind surpassed hydroelectric in 2019 as the predominant renewable source. Hopefully, the percentage of electricity from renewables will go up quickly in the coming years.

Three grizzly bears tested positive for avian flu in Montana - The animals were euthanized in the fall; suspected to have rabies, they tested negative. But they were positive for avian flu. The bears were ‘in poor condition and exhibited disorientation and partial blindness, among other neurological issues.’ So – the current outbreak of avian flu that has impacted wild and domestic birds (more the 52 million have been killed or culled to contain the virus) is impacting more than birds.

Drone video of moose shedding its antlers – Wow – it happened so quickly; the video is only 16 seconds! The moose just shakes its body, and the antlers fall off. It seems to want to leave the scene quickly once they are off too.

eBotanical Prints – January 2023

Twenty more books were added to the botanical print collection this month. Two series were from Australia: 8 volumes of A Critical Revision of the Genus Eucalyptus and 3 volumes of the Australian Orchid Review (there are many more volumes of the orchid review that I will browse in February). And there were two additional books about Australian plants: A manual of the grasses of New South Wales and How to know western Australian wildflowers.

The whole list of 2,552 botanical eBooks can be accessed here. The list for the January 2023 books with links to the volumes and sample images is at the bottom of this post.

Gleanings of the Week Ending January 28, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

What links litmus paper and lichens? – How did I not know that litmus dye was made from lichens? I remember using red cabbage to tint paper for an elementary school science project with my daughter. We tested everything in the house…discovered that even the fumes from toilet bowl cleaner turned the strips we made bright pink!

How donkeys changed the course of human history – The beast of burden. During Roman times the subspecies used was larger than modern donkeys…specifically bred for the expanding empire.

Jungle realm of the Snake Queens – A 5-part article about 2 Mayan queens: Lady K’abel and Lady Six Sky.

Marriage in Minoan Crete – A surprise – it was very common to marry one’s first cousin!

Kenya’s Rift Valley lakes are rising, putting thousands at risk – A study reveals that there have been increases in rainfall since 2010…an increase of only 0.4-2% of mean annual rainfall leads to the observed rising lakes/flooding.

EPA requirement keeps electric buses out of low-income schools – Low-income school districts often don’t own their school buses; they rely on contractors or subsidized lease deals. So --- they can’t meet the requirement to scrap the old diesel buses.

Ten-minute scan enables detection and cure of the commonest cause of high blood pressure – The hormone aldosterone causes 1 in 15 cases of high blood pressure. This new technology/treatment is a big improvement for the way those cases can be treated.

Dead Humpback Whale Washes Ashore at Assateague Island – This is the second one recently. I am familiar with the place this time…Assateague Island was a place my husband and enjoyed for birding when we lived in Maryland.

China’s population declines for the first time in six decades – Changing demographics in China.

Bees exposed to common weedkiller via wildflower nectar – Evidently the flowers can be contaminated even if they are not sprayed directly!

Nutting’s ‘Beautiful’ eBooks

Wallace Nutting started out his adult life as a Congregational minister but retired at 43 because of ill health. His ‘second act’ (he lived to be 79 years old!) included photography and colonial furniture collecting and reproduction; his reproductions and photographs are still widely collected today. Both aspects are represented in books he published and are available on Internet Archive. The ‘Beautiful’ books reflect his travels; he was evidently an avid bicyclist and took up photography to document what he was seeing. Nutting’s pictures capture places as they existed in the 1920s; since he tended to photograph landscapes, some of the places might look very similar today. The only one not in the northeastern US is Ireland!

The Internet Archive also has Nutting’s book documenting Windsor chairs – which he collected and reproduced. I selected a child’s highchair as the sample image…remembering my daughter sitting in a similar chair for lunch the first time she visited Mount Vernon (Washington’s home) and we stopped for lunch at the restaurant there (back in 1990).

 He’s a great role model of redirecting your life in a positive direction after encountering a roadblock (like ill-health) on the path you thought would be yours.

Our New Neighborhood – January 2023

It was warmer than I expected when I walked around our neighborhood pond…a pleasant surprise. I photographed the Lambs ear in our flower bed on the way out…both the mother plant and ‘children’ seem to be weathering the winter.

The dying back of vegetation makes it easier to see nests in the trees and the reeds/grasses at the side of the pond. Was this one built by a red-winged blackbird last spring?

There are many leaves decaying in the pond…and bright green algae. I wondered if there might be some interesting macroinvertebrates in the water. We did see a lot of dragonflies in the summer so their larvae might be in the water. Maybe I will get a small net to see what is hiding in the decaying leaves.

I always stop to look at the weeping willow at the edge of the pond that has grown around a metal stake. The leaves are gone now…but the lichen on the trunk is colorful! I took pictures at various magnifications with my phone (Samsung Galaxy S10e). I’ll continue to check the lichen on my walks around the neighborhood pond…see how much it changes when the weather is warmer.

Birds near the Lake Springfield Boathouse

My husband and I enjoyed a walk in the Lake Springfield Boathouse last week. The first bird I saw was an Eastern Bluebird! Unfortunately, I was dealing with glare on my camera’s (Canon Powershot SX70 HS) viewfinder/screen, so I didn’t get a very good picture.  I guess it was enough thrill to see the birds there.

There were some birds further out in the water…not very photogenic…but it seems that they are all mallards.

The most numerous birds we saw were black vultures – in a sycamore, warming up in the morning sunshine. There were three that seemed to be communicating with each other.

I photographed two birds almost too far out on the water – realized once I got home that they were scaups (male and female).

And then….a red-tailed hawk…perched at the top of a sycamore with lots of seed pods near the dam.  The bird’s breast feathers were fluffed against the cold. The area has more traffic, and I was glad the hawk did not seem disturbed by the noise.

Winter Meadow

Last week, my husband and I picked a sunny morning to walk in the Lake Springfield Boathouse area. It is an easy drive from our house along curvy 2 lane roads. It was cold enough for a jacket but the winds from the previous day were gone – so not uncomfortable. The place was very different that our previous visit back in September (see posts (1) and (2)). Now the lush meadow is full of dried vegetation…providing a very different photographic opportunity. It was so sunny that it was challenging to see the camera (Canon Powershot SX70 HS) screen or view finder!

In one of the open areas along the paved path, there was a gingko tree….complete with a few leaves from last season and the distinctive buds for next spring.

Back at the boathouse – I took a picture of a youngish sycamore near the water. Tomorrow I’ll post about the birds we saw on our walk.

Frost Ferns

18 degrees Fahrenheit and humidity at 98% in the sunshine shortly after sunrise. Those were the conditions shortly after sunrise a few days after we got some snow. I went outside on the patio for some macro photography.

My first stop was where there was some residual snow (and maybe some fresh frost) on the deck stair railing. There has been too much freeze thaw…maybe a little interesting, but not worth standing out in the cold to fully capture.

I looked around for another surface where frost crystals might have formed…took a closer look at the wrought iron table and charts. There were small crystals around the edge of the table! I set my phone (Samsung Galaxy S10e) magnification to 8x and walked around the table. Most of the crystals looked like ferns to me! I am going to check the table rim on upcoming cold mornings…and document how the forms of frost change with temperature and humidity. Enjoy the sideshow below to see the results of 18 degrees and 98% humidity!

Gleanings of the Week Ending January 21, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

How do snowflakes form? Is each snowflake really unique? Why is some snow light and fluffy or heavy? The amazing science of snow – A good topic to explore in the winter! The article includes a video of snow and ice crystal growth.

Falling birth rate in US not due to less desire to have children – People are not having as many children as they say they want, especially at earlier ages. There is some evidence that people reduce the number of children they intend to have as they get older. They may realize how hard it is to have and raise kids in the US…and decide to only have one child rather than two. They may have more challenges conceiving as they get older too. Larger economic and social forces are also impacting birth rates.

Meditation and mindfulness offer an abundance of health benefits and may be as effective as medication for treating certain conditions – An overview of the strengths/weaknesses of studies about mediation/mindfulness…a good introduction.

Drone Photography Celebrates the Beauty of Historic High-Rise Buildings in the U.S. – Wonderful views of the highest parts of tall buildings.

9 in 10 drivers in the US would save money on fuel by going electric – Good! Hopefully the cost of the electric cars will come down a bit…and we’ll have more models to choose from…and the places to charge them during road trips will be convenient.

Why obesity is more dangerous for men – Evidently men have a lot more inflammation associated processes and don’t grow as many new blood vessels in their fatty tissue.

See the Lavish Pompeii Home Owned by Two Men Freed from Slavery – Reopened after 20 years of restoration work. It was originally excavated in 1894-1895.

Broccoli looks more like cauliflower in a warmer world – Looking at the chemistry behind the changed growth of broccoli at higher temperatures…avoiding the change in the lab…but will it enable us to still produce broccoli that looks like broccoli as the planet warms?

Another step toward an insulin tablet - A lot of diabetics would appreciate ‘no more injections’!

Why Electrifying Everything Is a Critical Pathway to Decarbonize The World & Our Lives – I like these articles that get specific about the options that individuals/families can take. It gives me more hope for my future and the future of the planet to take the actions I can to 1) decarbonize the electricity used by my home, 2) move toward an all-electric home and transportation, 3) improve efficiency/reduce waste, and 4) sequester carbon. Focusing on the ‘all electric’ concept this week. I have natural gas powered heating and hot water heater…will probably replace the heating/cooling first. The gas fireplaces are turned off already – removing them is not a high priority.

Travels of Sven Hedin

The week’s book post includes 13 books…travel books written and illustrated by Sven Hedin from the late 1800s to the 1930s…available from Internet Archive. As usual – my interest was primarily in the illustrations which include drawings, watercolors, and photographs. The author was Swedish geographer, topographer, and explorer…and the books are his documentation of his work. His sketches of people and places…as well as a picture of himself outfitted for very cold weather in Tibet…make these books good windows into the places as they were.
