Ice and Algae

/

It was below freezing for almost 24 hours before I ventured out last week an hour or so after sunrise. The temperature was in the 20s and I anticipated capturing ice on our neighborhood pond. I bundled up in my heaviest coat and gloves…already had the lens cover off my camera since it is hard to remove with gloves on.  I noticed the robins were around and probably beginning to scout nesting locations.

There was a small group of Canada Geese; most stayed on the bank but two ventured into the pond through mats of algae. I began to worry that maybe the sun shining on the pond surface had already melted the ice even though the air temperature was still below freezing!

As I looked more closely I noticed that there was ice between the mats of algae! Some of the ice had a look of cut glass. There were leaves just under the surface in some places – distorted by the ice – but some are, quite clearly, oak leaves. The color of the algae is a nice contrast with the ice!

My favorite picture of the morning was a patch of ice surrounded by algae. The green mats creates a fuzzy (slimy?) frame around the ice structures.

I continued aroud the pond and noticed that a twig of red maple flowers had fallen onto the path. The tree blooms so early that the hard freezes sometimes are problematic. The red maple that this twig came from seemed to still have quite a few flowers that had tolerated the cold so the tree should still be producing seeds this year.

Overall – I’m glad I went out when I did. This could be one of the last times to capture ice on the pond since spring is one the way.

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….

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.

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!

Our Missouri Neighborhood – February 2023

/

There were a few days of snow and ice early in the month; I stayed indoors for the first days but then the sun came out and I decided to bundle up and walk around the neighborhood to document the event. The pumps in the largest pond were keeping some open water.

Two geese ventured out on the ice…but turned around and rejoined their friends on the bank before getting all the way to the unfrozen part of the pond.

The snow that fell on the slides in the playground had gone through some freeze-thaw cycles and was extending past the end of the slides!

The contrast of tree trunks and snow/ice was stark…the snow creating a different pattern than usual when the mulch around the trees is almost the same brown as the tree trunk.

My favorite sights of the morning were the neuron shapes in the pond. My theory is that the center part that looks unfrozen is either a shallow spot or has a lot of water plants near the surface. The ‘dendrites’ coming out from the center are cracks in the ice that are mostly refrozen. I zoomed in on one of the centers; the texture of the ice looks like cut glass!

Or maybe I was just thinking about neurons too much since I’ve been learning about them recently…stay tuned for tomorrow’s post for more about that.

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.

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!

Josey Ranch – January 2023

/

The birds on the water at Josey Ranch in Carrollton, TX changed from when I was there in December. The Northern Shovelers were not there in January! The American Wigeon were there the first day I went in January but not on the second. It seems a little early for them to be migrating; maybe they have moved to a bigger pond. On my first visit – I saw American Wigeon, Lesser Scaup, American Coot, Great Egret, Ruddy Ducks, and gulls.

The surprise birds of the day were a pair of Buffleheads. They were busy diving for food! I’ve seen them occasionally at Josey Ranch before but they are not in the ‘regular’ birds there.

On the second day I visited, there were gulls lined up on the walkway near the parking lot. The Lesser Scaup, American Coot, and Great Egret were still around. The mallards seemed more numerous than on the first day (seemingly skewed toward males). There was a Great Blue Heron almost hidden in the reeds. The Ruddy Ducks were still there but sleeping just as they were on the first day.

I walked around to the native plants in a terraced area between the Library and Senior Center. It was almost too windy for macro pictures…but I tried anyway. Some berries were the only color….but the shapes of the dried remains of the plants from last summer are interesting enough.

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.

Carrollton Yard – January 2023

/

I was in Carrollton, TX the last week of January. It was almost spring-like on a day early in the week. I took pictures of the yard – dried or frost damaged vegetation – but noticed signs of spring as well: the Japanese quince in bloom, the fronds of the naked lady lilies up through the mulch and some new leaves on the rose bushes. The oxalis had recovered from the deep freeze in December…providing swaths of green in the flower beds.

The bird feeder is very popular with a flock of house sparrows. They like the larger seeds – often flying to nearby bushes with their seed – leaving the feeder available for their friends. There are occasional chickadees and house finches that comes to the feeder too.

The mourning doves clean up the seeds on the ground – the rejects of the feeder birds.

There seemed to be more robins around in the front of the house – another sign that spring is on the way!

Ten Little Celebrations – January 2023

/

January is usually the calm after the flurry of holidays and other big celebrations in November and December. Still - there are plenty of little celebrations to choose from; these are the top 10 for January 2023.

50th wedding anniversary. My husband and I celebrated our 50th anniversary….a delivered lunch with our daughter. Our anniversary celebrations have always been relatively low key; this year I thought more about my parents’ 70th anniversary back in December…savoring enduring relationships with my family.

A new low weight for the year. I put on some weight in November and December. I put myself on a “healthy food” diet (logging my food into the Cronometer app) and celebrated that it worked…slowly but surely taking off pounds!

Lake Springfield. A winter meadow…and black vultures. Celebrating being outdoors in winter.

Another frost data point. I celebrated getting a second frosty morning to add to my project…noting temperature and humidit and photographing the crystals.

Hurray – bone density results still in the ‘normal’ range. Every time I get new bone density check, I am always a little anxious. I am leery of medications to treat bone density issues so I’m glad my preventative exercise - calcium – magnesium – Vitamin D regime seems to be maintaining my bones.

A sunny day in Carrollton (and seeing a downy woodpecker). After clouds and rain, a sunny day is always welcome and seeing a small woodpecker getting breakfast in a tree near a window adds to the celebration.

Coursera anatomy course. Starting a new course…celebrating filling in gaps in what I already know. Its always fun to slip back into the student role.

Pumpkin custard with peanut powder. I celebrated the success of my culinary experiment of the month: adding a cup of peanut powder to pumpkin custard (and rounding up on the spices). Yummy…and high in protein.

Snow (pictures) from Nixa/Springfield. I celebrated the event while I was in Texas.

Frosty morning in Carrollton. I added 2 frost events into my project while I was in Texas…celebrated that the conditions were cold enough…humidity high enough too.

Zooming – January 2023

/

Birds (Great Egret, Northern Shoveler, Great Blue Heron, Northern Pintail, Red-tailed Hawk)….evergreens…dried (or frost damaged) plants…Texas sky - January was good month using the optical zoom on my camera! The locations were Texas (Carrollton, Hagerman National Wildlife Refuge) and Missouri (Nixa, Springfield). Enjoy the slideshow!

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!

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.

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.

2023 Diet (Strategy)

/

I am thinking about my diet strategy for 2023. It’s a mix of things that have worked before to keep my focus on nutrition and moving toward a sustained ‘normal’ weight…skewed toward lowering my carbon footprint.

  • Use the Cronometer app to watch nutrition and calories until I am at the ‘normal’ weight for my height. This worked for me 5+ years ago so I am going to do it again now that I have gained a few pounds. It is important to sustain a healthy weight rather than yo-yoing. Using the app I know I am getting enough protein; if I need to reduce something to get the calories low enough, it is usually a fat…and I want all the calories to go toward meeting nutritional goals.

  • Reduce ultra-processed foods (those foods that have a long list of ingredients…some of them unrecognizable). The hardest might be soft drinks. I also notice that when I travel, there are more instances of ultra-processed foods in my diet.

  • Eat less red meat. In 2022 it was about half my protein. In 2023, I want to reduce it to 25%. I’ll ramp up eggs, chicken, turkey, and vegetarian sources of protein (although I am not keen on the vegetarian sources of protein with ingredient lists that indicate they are ‘ultra-processed’).

  • Become vigilant about avoiding lactose. The Lactaid does not seem to totally solve the problem anymore, so it is better to avoid the foods. The big change is moving away from Lactaid Milk to Soymilk. Deciding what to eat when I travel will be a bit more challenging as well.

The theme for my 2023 diet is:

‘Good for me…and for the planet.’

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.

Study investigates source of Amazon’s “Dark Earth” – Created intentionally? It is less acidic than surrounding soils…probably from the addition of ash.

New York City Greenery Absorbing All Traffic Emissions on Many Summer Days – There is a lot more greenery that previously thought…looking beyond parks to modest backyards, shrubbery growing in vacant lots, and trees dotting city sidewalks. That’s good for the summer when everything is green and growing….but it also implies that winter air quality is problematic.

‘Stomp’ Performers Hang Up their Garbage Lids – After 3 decades off-Broadway. Watch the video!

Riddle solved: why is Roman concrete so durable? – It wasn’t just volcanic ash that made Roman concrete better…lime clasts play a self-healing role!

Why is every parking lot covered with solar panels? – Evidently Michigan State has done it…hopefully other universities and big box stores do similar projects. 

How the war in Ukraine is killing marine mammals – The dolphins that were washing up on the shore of the Black Sea prior to the war were few and usually had markings suggesting entanglement in fishing gear.  The theory about the increased number appearing now, without marks, is that the dolphins are experiencing acoustic trauma from the increased use of sonar by Russian submarines.

Climate impact labels on sample food menu had strong effect on food selection – A study done by Johns Hopkins. The result indicate that this kind of labelling could promote more sustainable choices….and have positive health benefits as well!

Aerial Photos Capture the Abstract Beauty of Salt Ponds – From a new book….with images and background about these man-made landscapes.

Great Salt Lake will disappear in 5 years without a massive ‘emergency rescue’ – My husband and I visited the lake back in 2008. The pictures in the article are so different that I needed the captions to recognize the place. The lake was already shrinking in 2008 but the shrinking has increased with long term drought and increased population diverting more water that would otherwise flow into the lake. Aside from the ecological collapse if the lake goes dry, the dust from the dry lakebed is kicked up by winds and can damage lungs/exacerbate other respiratory illness. This does not bode well for public health in Salt Lake City.

Painted skulls from Peru’s Chincha Valley analyzed – The red paint on the skulls was not all the same on all the skulls: some have iron-based ochres and others have mercury-based cinnabar….the red paint on one of the skulls was a combination of the two!

Cancer Diary – Entry 13

/

It’s been a year since my cancer surgery. All the diagnostics at the one-year mark show that I am cancer free….so the surgery was a success.

My last post was 4 weeks after the surgery but now I realize I should have done a post at 8 weeks since that is when the hematoma was finally gone. And two weeks later, in the area where the last hematoma color had been, cellulitis developed. The cellulitis might have been unrelated to the surgery, but it was a first instance of cellulitis for me…disconcerting; it was quickly resolved by antibiotics (unfortunately, I develop a reaction to the first type prescribed right after the second dose).

My fingernails became very brittle in the spring. They have returned to normal now. I suspect that the surgery and associated medication change might have been an issue but that my body had recovered/acclimated at this point.

The scar and puckering around it are not fading as quickly as I expected – perhaps because of skin sensitivity to the recommended topical vitamin E and/or cocoa butter and sunscreen, developing hives in the scar area (reaction to an antibiotic), and the silicon patches not being as effective as advertised. My current strategy is to cover the scar when I am out in the sun (rather than using sunscreen) and to use the mildest of moisturizers.

My cancer was detected early before it impacted my perception of health, and the surgery happened expeditiously. A year later, I am feeling healthy (almost like I felt before the surgery) but 2022 had the most health related ups and downs of my life!

Hagerman National Wildlife Refuge – December 2022

/

Back in November, I stopped at Hagerman National Wildlife Refuge on my way down to Carrollton, TX. It is just outside Sherman, TX…a little over an hour away from my destination. The refuge was active in the early afternoon…with some migrants still around (link to November post).

In December, I opted to do a quick drive through on my way home so it was in the morning about an hour after sunrise; it was not a great time for seeing large numbers of birds. It was too late to see birds that had roosted in the ponds…and it was too cold and windy to linger very long with the windows open (I was using my car as a mobile blind).

I enjoyed seeing a flock of male red-winged blackbirds in stubble near the road….rise up as a group then coming back down like a wave crashing on beach to feed again…repeat. Their red and yellow markings were flashing every time they started up out of the dried vegetation and when they landed again.

A heron stood in the shallows with its feathers ruffled by the wind. The day was still new enough for the water to be morning blue.

I also saw a Harrier Hawk – hunting…circling over the stubble and water’s edge. I didn’t get a picture, unfortunately, but I spent a few minutes watching the awesome grace of the bird dealing with the wind and looking for breakfast.

The clouds began to cover the sun periodically and I took some refuge landscape shots – complete with oil pump jacks (it is Texas).

The pintails, mallards, and shovelers were around….enjoying the bounty of the refuge.

Gulls were mostly staying put in the shallows.

My plan is to stop at the refuge as I continue to make monthly treks to Carrollton…see the changes at the refuge as the winter progresses….and then the spring migration and flowers.

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.

Macro Photos Highlight the Diverse Beauty of Butterfly Pupae – The pupae are Asian species….so no Monarch chrysalis (which is my favorite).

Good hydration linked to healthy aging – The findings don’t prove a causal effect…but hydration is linked to serum sodium…and chronic high serum sodium (i.e. when a person is dehydrated frequently) increases risk of developing chronic diseases like heart failure, stroke, atrial fibrillation and peripheral artery disease, etc.

The Infrastructure Sector Is Bleeding Workers – The workforce is aging…more are nearing retirement…and younger people are not coming into the jobs fast enough.

This new year – decarbonize your life – The beginning of a series about a family of 4…taking steps to dramatically reduce emissions and sequester carbon.

Gradient Arrangements of Food Highlights Biodiversity Not Often Seen in Supermarkets – Wow – what a range of colors and shapes in common fruits and veggies like: tomatoes, corn, potatoes, pears, peppers, squash, cucumber, kale, and beans.

Heat and cold as health hazards – Controlled experiments on how the body reacts to hot and cold…and the health consequences.

Water Worries: Threatened and Endangered Cultural Sites – Climate change has caused increasing severe rainstorms in the Southwest impacting the adobe walls  in Tumacácori National Historical Park in Arizona and Pecos National Historical Park in New Mexico. Storms, flooding and sea level rise are impacting other parks including Statue of Liberty National Monument, Colonial National Historical Park and the Jamestown Settlement, and Castillo de San Marcos National Monument. The tidal basin in Washington DC is crumbling as flooding increases as the Potomac River rises.

Researchers identify bird species depicted in ancient, finely detailed Egyptian painting – Click on the images to get a larger view of the birds. Key to the second image: a–f rock pigeons (Columba livia); g red-backed shrike (Lanius collurio); h white wagtail (Motacilla alba); i pied kingfisher (Ceryle rudis); j–l unidentified.

How microplastics are infiltrating the food you eat – Right now microplastics are viewed as a contaminant but research is revealing they may have harmful impacts….and should be studied and regulated as a pollutant. Will systems that use sludge as fertilizer need to change dramatically? It appears likely.

2022 Year in Review: Top Stories from Around the National Park System – Flooding at Yellowstone, Mauna Loa eruption, drought at Glen Canyon, maintenance challenges, invasive species …crowds…a lot of big stories.
