Frost Columns and Ferns

/

There was frosty morning last weekend at our house, and I photographed the crystals about 30 minutes after sunrise…in a hurry because the temperature was 20 degrees Fahrenheit, and I hadn’t put on my coat! There was frost on the lamb’s ear and an old leaf that looked like crystals of sugar.

\I was more interested in finding more complex crystals. Our wrought iron table had frost all around the outer edge.

The first ones I saw were columns…sometimes in clumps…emanating from films of ice (that might have started out as water).

I was surprised to find very different crystals on the other side of the table! They were a lot like the frost ferns I posted about back in January. They were not quite as large, and they grew out of a thin film of ice rather than as ‘fronds’ around a common center as they had in January.

I wondered what caused the crystals to be different on opposite sides of the table. In the past, I found column type crystals when the temperature was closer to 30…the ‘ferns’ when it was 20 or below. The columns were on the side of the table closer to the hollies and some cedars; the ‘ferns’ were on the side next to the posts supporting the deck stairs. Could the vegetation be creating a slightly warmer temperature? Maybe next time – I’ll take a thermometer out to test that idea!

All photos were taken with my Samsung Galaxy S10e (most are at 8x magnification).

Our Nixa, MO Yard – February 2023

/

February started out bitterly cold – with sleet/snow that stayed on the ground for days. I bundled up and ventured outdoors with my camera to document the situation in our yard. There had been some freeze-thaw cycles already, but the concrete and rock covered beds were still very white. A downspout had dribbled water than had frozen before it could escape. In the yard, the grass bristled through the whiteness; I left footprints, but they didn’t go very deep. The yard was pristine; our Missouri yard (and neighborhood) is not a deer highway like our Maryland house was.  The iris leaves in one bed seemed unfazed by the cold (hope that continues to be true!).

I went through the house to go out to the front because all the gates were frozen in place. I was surprised that mine were the only footprints on our sidewalk; with schools closed and the bitter cold, people were not taking walks as usual.

I was intrigued by the round seed pods on one of our larger crepe myrtles. The wind and gravity had emptied some of them, but others still contained the seeds from last fall.  The seeds were ready to scatter…they fell out easily with a nudge of my fingernail.

Frosty Valentine’s

/

Valentine’s Day is a very commercialized celebration --- lots of red roses, chocolate and other candy often in red heart shaped boxes or the candy itself in the heart shape. If my husband and I do anything for Valentine’s – we do it on our monthly wedding anniversary which is within a few days of the 14th. This year it will be our 601st monthly anniversary!

One positive outcome of the commercialization of the celebration, I am anticipating lots of candy on sale on the 15th….hoping for a good selection to buy at a reduced price for my daughter and son-in-law to have in their campus offices for their meetings with students!

Another positive aspect to Valentine’s is its position in February. The winter can be gray, cold, and icy. Maybe Valentine’s Day should be a prompt to look around for beauty in the ‘wild’ to share with someone near and dear: a sunrise or the beauty of ice crystals at close range….choose to see beauty in February outdoors (or through a window)!

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.

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.

Carrollton Frosts – January 2023

/

There were two frosts in late January when I was in Carrollton. The first day started out at 30 degrees and 96% humidity. I made the first round of pictures around the yard of my parents’ house not long after sunrise.

Frost covered the upper surfaces of everything.

The seed pods of the red yucca are my favorite images – coated with frost that highlights the ridges and folds of the pods.

I went inside for about an hour then photographed more plants and objects. The crystals on a tiled counter near the gas grill were the largest (mostly columns).

On another morning, the temperature was 34 degrees and the humidity was not as high…but frost formed anyway. I wondered if the oxalis would be able to withstand the two days of frost. The tiled counter was encrusted with crystals again.

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.

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.

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.

Missed the Snow at Home - Again

/

I was in Texas last week when I snowed at home in Nixa, Missouri – this is the third snow in Missouri that I’ve missed entirely! This time there was about 5 inches of snow overnight. I enjoyed the event vicariously through pictures.

My daughter sent pictures of the snowy scenes from her windows in Springfield first thing in the morning; she has big plans to enjoy her Snow Day. Her house is on a corner; one street was plowed but it wasn’t the one her driveway is on! The magnolia – with its big leaves – held clumps of snow. Even the maple, that doesn’t have any leaves at all, looked flocked.

My husband sent pictures a bit later. Around our house, the pines and hollies held a lot of snow. There were tracks in the snow from an animal – not sure what it could have been; the area we live in now is not at all like our Maryland yard that seemed to be a highway for deer heading back to the forest.  

I was surprised that the Japanese dogwood (a deciduous tree) held so much snow. I checked it when I got home and was glad that none of the branches seemed damaged.

My husband walked out our back gate and then around the pond. It was a winter wonderland!

Maybe eventually – I’ll be at home when a big snow event happens!

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!

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!

Morning Fog and Moon

/

I went outside just after sunrise to photograph the fog; there had been no color with the sunrise because the fog was so dense. There was an advisory for the morning commute and I was glad I didn’t have to leave the house. Then I looked up and saw that the sky was quite blue and the moon distinct! The blanket of fog was clearly thin and close to the ground!

I am a morning person. This time of year, I am always up before the sunrise and ready to welcome the light of the new day. A colorful sunrise is always welcome but sometimes clouds and fog can be just as interesting because they alter the perception of surroundings. Noticing the beginning of the day…however the increase of light happens…is the best way to start my day.

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.
