Physical therapy (1)

My first session of physical therapy for lower back pain was just before Thanksgiving. I have 2 appointments per week through December – with a week off while I am out of town. It will be fabulous if this round can be as successful as the one about 20 years ago when I had a shoulder problem.

It has started out with very simple exercises for me to do twice a day. I’m sure it will ramp up to more challenging ones soon since the first ones are very easy for me. I am optimistic that it is going to help because of my previous experience and because the therapist has already made some suggestions that are helping me move without hurting!

It feels great to be ending the year with this type of activity…doing something that has the potential to enable me to start 2025 in better physical condition than I’ve been in 2024!

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

How the Groundbreaking Suez Canal Forever Transformed the World’s Shipping Routes – The official opening ceremony was on November 17, 1869. It had taken 10 years to build on the path of an ancient canal and was called “the greatest service to the commerce of the world since the discovery of America.” The project was funded mostly by Western Europe.

'Jekyll and Hyde' leaders do lasting damage - When supervisors swing between good and bad behavior, they do even more damage to their employees than ones that are abusive all the time. And there are some indications that this kind of leadership could be contagious, with a leader's volatility fostering volatility in others

Scientists find a 35,000-year-old saber-toothed kitten in the Siberian permafrost - The cat was just three weeks old when it died, but its cause of death is unknown. The kitten still had its whiskers and claws attached when it was pulled out of the permafrost, and was covered in a coat of short, thick, soft, dark brown fur. Its hair was about 20 to 30 millimeters long. When looking at the mummified cub, scientists found some interesting differences between the kitten and a modern lion cub, particularly, in their paws: the saber-toothed kitten had wider paws, but no carpal pads — that's the wrist joint that's help modern day felines absorb shock.

Hatchling Alligators at the Fort Worth Nature Center – The Dallas/Fort Worth area is at the edge of American Alligator range…but the Nature Center has confirmed that it has a breeding population there. The Fort Worth Nature Center is 3,650 acres of mixed habitat, owned and operated by the City of Forth Worth; it is one of the largest city-owned nature centers in the US. There is an alligator research project ongoing there now that the breeding population has been discovered.

Sitting too long can harm heart health, even for active people - 10 hours or more of sedentary behavior per day is associated with heightened risk of heart failure and cardiovascular death. I am so glad that I decided years ago to use a Swopper chair (without a back…bouncing) at my computer desk….so I am moving most of the time that I am there!

Bone marrow in the skull plays a surprisingly important role in ageing - Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflammation and other hallmarks of ageing.

Glaciers Reveal When Volcanoes Are on Brink of Eruption - New research shows that glaciers near active volcanoes flow faster than other glaciers. The findings suggest it would be possible to predict volcanic eruptions by tracking the speed of glaciers.

Can we live on our planet without destroying it? - With eight billion people, we currently use a lot of the Earth's resources in ways that are likely unsustainable. Research shows that humanity can stay within the planetary boundaries. But it seems that there is little political will to do so. A depressing commentary on humanity.

Memories are not only in the brain - In the future, we will need to treat our body more like the brain -- for example, consider what our pancreas remembers about the pattern of our past meals to maintain healthy levels of blood glucose or consider what a cancer cell remembers about the pattern of chemotherapy.

Astronauts of the underworld: The scientists venturing into the deep, dark Earth - Hundreds of cave entrances are known on Earth, the Moon, even Mars. Many have never been explored.

Nevin Otto Winter Travel Books

This week’s books are 9 well-illustrated travel books by Nevin Otto Winter published between 1910 and 1918. I was most interested in the illustrations – mostly photographs – although the narrative would serve to understand the perspective of an American traveler of that time period encountering foreign customs. I picked two sample images from each book to include with this post but follow the link to Internet Archive to experience the whole book. Enjoy!

How a Soviet swamp rat scheme for Azerbaijan went horribly wrong – Nutria introduced in the 1930s…..destroying every wetland in Azerbaijan today.

Light Pollution May Be Keeping Honey Bees Up at Night - On hot nights honey bees will sleep outside and slept less/more fitfully if there is artificial light…which could undermine the health of the colony.

The next massive volcano eruption will cause climate chaos — and we are unprepared – The history of large eruptions and what we can determine about the aftermath…though provoking on what it would be like if a massive eruption happened in the modern world.

Carbon recycling instead of plastic trash – Using iron electrocatalysis and producing green hydrogen as a biproduct…can be powered by solar panels. I hope this can be commercialized near term. We are overwhelming our world with plastic trash!

CT Scans Unlock Secrets of Mummified Individuals at Field Museum – Respect for the ancient dead…but still studying their bodies.

How do countries measure immigration, and how accurate is this data? - Three types of migrants who don’t have a legal immigration status. First, those who cross borders without the right legal permissions. Second, those who enter a country legally but stay after their visa or permission expires. Third, some migrants have legal permission to stay but work in violation of employment restrictions. Most high-income nations have a small minority of irregular immigrants in their immigrant population; the exception is the United States which estimates 22% of their immigrants are irregular.

Riding The Rails on Amtrak's Cardinal Line Through New River Gorge – Maybe a relaxing way to see the National Park and Preserve…thinking about next fall.

Mother Tiger Teaching Cub How to Fight Wins Nature’s Best Photo Awards – Great pictures….but Patricia Homonylo’s video is the most thought provoking….the one that is a call to action.

Geologists rewrite textbooks with new insights from the bottom of the Grand Canyon - From the Tonto Group's 500-meter-thick strata, we're learning about sea-level rise and the effects of catastrophic tropical storms -- probably more powerful than today's devastating hurricanes -- during a period of very hot temperatures when the Earth was ice-free.

Quantifying How Urban Trees Cool Cities - The authors of a new study estimate that the city of Baltimore could reduce land surface temperatures by 0.23°C if they increased tree canopy by 1%. To achieve 1.5°C of cooling, they would need to increase tree canopy cover by 6.39%.

Robert Edwin Peary’s Arctic

Robert Edwin Peary’s Arctic explorations in the later 19th and early 20th centuries are documented in 6 books he published between 1898 and 1917. They are available on Internet Archive and worth browsing. They are all well-illustrated…attempting to show every aspect of Arctic exploration and Inuit life too. I’ve selected 2 sample images from each book…hopefully enough to encourage browsing the books for yourself!

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.

Drought Expands Across the U.S. – We are finally getting some rain…but we are in the ‘extreme drought’ area of southwestern Missouri; it is going to take a lot to get back to ‘normal.’ On October 29, abnormal dryness and drought affected over 78 percent of the American population—the highest percentage in the U.S. Drought Monitor’s 25-year-long record.

Cholera, Zika and West Nile: The deadly diseases that sweep in after hurricanes – Damage to infrastructure has been the big focus of reporting in the US, but diseases are ramping up.

  • Florida health authorities released a warning in early October of a likely spike in Vibrio vulnificus infections, urging residents to avoid wading in floodwaters.  Vibrio vulnificus is a bacteria which can cause the breakdown of skin and soft tissue, sometimes leading to amputations.

  • West Nile cases rose in Louisiana and Mississippi following Hurricane Katrina.

  • Studies found that flooding in Louisiana following hurricanes Rita and Katrina led to an increase in the airborne fungi Penicillium and Aspergillus, which can cause allergies, respiratory infections and pneumonia.

  • Research into the aftermath of hurricanes Maria, Irma and Michael, shows that a significant number of people in Florida developed new chronic health conditions such as asthma and allergies in the six months following the disasters.

Satellite Imagery Shows Breadth of Flooding in Spain - Valencia saw a year’s worth of rainfall in just eight hours, with floods destroying buildings, disrupting trains, and leaving more than 100,000 homes without power.

What animal societies can teach us about aging - Humans are not the only animals to change our social behavior as we age. Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off.

The world’s oldest tree? Genetic analysis traces evolution of iconic Pando forest - By sequencing hundreds of samples from the tree, researchers confirmed that Pando, a quaking aspen tree (Populus tremuloides) in Utah, is between 16,000 and 80,000 years old. Pando consists of some 47,000 stems that cover an area of 42.6 hectares in Utah’s Fishlake National Forest. Because of the way the plant reproduces, this collection of aspens is technically all one tree, supported by a single, vast root system. Pando is triploid, meaning that its cells contain three copies of each chromosome, rather than two. As a result, Pando cannot reproduce sexually and mix its DNA with that of other trees, and instead creates clones of itself.

Have we found all the major Maya cities? Not even close – Using lidar to survey 50 square miles revealed evidence of more than 6,500 pre-Hispanic structures, including a previously unknown large city complete with iconic stone pyramids.

Stunning Shortlisted Photos From the 2024 Close-Up Photographer of the Year Contest – My favorite was “Chicory” for the color…and that I knew what it was!

Low-level lead poisoning is still pervasive in the US and globally - Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children. Factors such as menopause and hyperthyroidism release lead sequestered in the skeleton, which causes a spike in blood lead concentrations. The solution to protecting people from lead poisoning is to identify and eliminate environmental sources of lead: eliminating lead acid batteries, replacing lead service lines, banning leaded aviation fuel, reducing lead in foods, abating lead paint in older housing, and further reducing lead-contaminated soil and other legacy sources.

Ghost Forests Creep Into North Carolina - Large swaths of cypress and pine forests along the southeast Atlantic coast have died, shed their bark, and become pale, leafless snags that line the waterways like gravestones. In the period before winds topple the snags over and shrubs cover them up, researchers call the eerie ecosystems “ghost forests.” One place that is it happening is Alligator River National Wildlife Refuge…and I realized I have been there! We visited in April of 2015. It was the first place I saw river otters and two vultures (different species) sharing a meal. There probably were bald cypress dying in 2015, but it is even more evident now.

Trees cool better than reflective roofs in vulnerable Houston neighborhoods - Heat islands occur in cities where structures such as buildings and roads absorb the sun's heat more than natural landscapes such as trees and grass. The researchers considered three different heat island mitigation strategies: painting roofs white to increase solar reflectance; planting vegetation on roofs to increase evaporation through the plants; and planting more trees, which increases evaporation and provides shade.

Wm. H. Edwards’ Butterflies of North America

As we head into winter – I am thinking about butterflies…how I didn’t see as many (or any species) this past summer. Maybe it is the drought in our area, and they will be more numerous next year. I hope so.

Edwards’ volume is the first of three he produced in the 1870s. The illustrations were done by Mary Peart and hand colored by Lydia Brown and often include more than simply the adult butterfly in the later volumes. They are well worth browsing.

The butterflies of North America

 I’ve not thoroughly browsed the other two volumes yet but I think I found them on Internet Archive as well: Volume 2, Volume 3.

Sustaining Elder Care – November 2024

I have two book/puzzle sorting days at my community library before I go off to Dallas again…I am hoping to find some more 300-piece puzzles to take for my Dad. I think he is probably running a bit low and maybe my sister is bringing some older ones back that he hasn’t done recently. We don’t have as many 300-piece as we do 500…and those 500-piece ones are getting too hard for him.

The past month has been more stressful in terms of elder care than I anticipated. There is a disagreement between us daughters about whether he is having pain when he eats and he needs his food ground up. Observations of him eating are not consistent. We have asked the dentist he saw last to make an assessment….since to make the change in mealtime routine for the assisted living staff will require a doctor’s order.  On the plus side – I don’t think my dad is aware of the turmoil. Most of the interaction among my sisters and I is via text; I’ve stopped looking at the messages about an hour before bedtime to try to reduce the impact on my sleep. It’s also caused me to start thinking more about what I want my relationship with my sisters to be separate from our shared interest in our father’s well-being.

13th Anniversary of my Blog

This is the 13th anniversary of this blog space. It all started when I made the firm decision to retire and started a daily blog…a few months before my career formally ended. It was a way for me to guarantee a little bit of structure in what loomed as a time of my life without many external requirements on my time.

Work had dominated so much of my time – way more than my college education during the first decade of my career…more than my daughter’s 1st 20 years in decades 1.5-3.5 of my career. My husband has been a constant through it all  - both of us putting considerable time into our careers. Mine ended without a glide path (intentional on my part)….his was a glide that finally ended a few years after my retirement. We both were aware of developing new ways to fill our days with a mix of activities that we chose – sometimes very different from things we did while our careers were active.

Writing a daily blog has had a positive impact on furthering my artistic side…and sometimes spurring me to action.

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.

Old Growth – Mitch Epstein photographs of very old trees.

The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

  • Embedding well-being into curricula for broader, more accessible adoption.

  • Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

  • Tailoring initiatives to the student body and university culture.

  • Securing buy-in from faculty.

  • Ensuring new offerings are accessible and don't create additional financial burden for students.

  • Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

A Hand-book to the Order Lepidoptera

William Forsell Kirby was an English Entomologist that authored a 5-volume Handbook to the Order Lepidoptera in 1896 and 1897. I am featuring the 1st volume as this week’s ‘book of the week’ because I was so pleased to find it. I had somehow browsed the other 4 volumes back in 2016! Enjoy the 4 sample images….and follow the link to see many more.

Astonishing Photo of Millions of Monarch Butterflies Wins 2024 European Wildlife Photographer of the Year Contest – Starting out the gleanings list this week with beautiful images from nature.

Iceberg A-68: The story of how a mega-berg transformed the ocean - Scientists following A-68's birth and demise were able to track just what such giant icebergs do to the surrounding ocean. For its short, transient life as an iceberg, A-68 became a frozen lifeboat for a wide range of species. Over its three-and-a-half-year journey since it broke away from the Antarctic ice shelf, A-68 lost 802 billion tons of ice as it thinned from an average thickness of 770ft (235m) to 551ft (168m). Over a three-month period at the end of 2020 and start of 2021, it dumped an estimated 152 billion tons of fresh water into the ocean – that is equivalent to almost 61 million Olympic-sized swimming pools. At the peak of its breakup, around 1.5 billion tons of fresh water was gushing into the ocean every day. The crushing weight of the freshwater from A-68a as it melted may have helped force carbon-based material down more quickly, to depths where it was less likely to be eaten.

Salmon Make a Long-Awaited Return to the Klamath River for the First Time in 112 Years, After Largest Dam Removal in U.S. – Four dams blocked the salmon’s migration between the Klamath basin and the Pacific Ocean…but now the dams have been removed, and the fish are returning. The first salmon in the river since 1912 were spotted less than two months after the last dam was removed.

Avian architects: weaver birds in Africa have unique building styles – The African white-browed sparrow weavers build nests that look like pompoms in acacia trees. Some families build roosts that are very long, with long entrance and exit tubes; others will build roosts that are much shorter, with hardly any tubes. Essentially, it looks like different white-browed sparrow weaver families have different architectural styles. Researchers excluded all environmental and genetic explanations for the differences in the structures built by different families. Maybe, like humans, some species of birds have their own architectural traditions passed on across generations through social interactions.

Huge! A Roman Engineering Marvel Reaching Across a Spanish City - In Segovia, the Romans built an aqueduct that stands as arguably their greatest architectural legacy from six centuries in Spain. After drawing water from the Frio River, the aqueduct runs underground for some 10 miles before appearing in Segovia as a grand, elegant beast that strides for nearly 2,400-feet across the town. Comprised of more than 20,000 blocks of granite and erected without a lick of mortar, at its highest point the aqueduct reaches more than 90-feet high with narrow, double arches. It remained in use until the late 1970s.

Life-saving spongelike 'bandage' rapidly stops hemorrhaging and mitigates risk of infection - A liquid gel comprised of siloxanes (silicon and oxygen) that is delivered via a special two-chamber syringe which rapidly expands into a spongy foam upon exposure to each other within the wound in under one minute. The sponge applies pressure to restrict the hemorrhage at the delivery site while also serving as an antibacterial agent because of the silver oxide in it.

Learning in the Environment: The Importance of Expanding Outdoor Education Across the United States - Although environmental discussions are expanding in schools, students often lack the opportunity to interact with the natural world through outdoor education, including place-based learning located in nature. The widespread decline of green spaces, especially in densely populated areas, restricts youth engagement with the environment. Interacting with the outdoors helps students to understand not only the environment itself but the role they can play in protecting it.

Chickpeas: Sustainable and climate-friendly foods of the future - Chickpeas are a drought-resistant legume plant with a high protein content that can complement grain cultivation systems even in urban areas. I have discovered that roasted chickpeas is my favorite ‘crunch’ topping for soups and salads!

Photo Contest Celebrates Excellence in Architectural Photography – I haven’t done much architectural photography…but maybe it is something to consider…when I am not able to do nature photography (which is my favorite).

Grasslands live in the climate change fast lane - The rapid shifts in grassland communities involve not only the gain of some hotter, drier species but also the loss of some cooler, wetter species. These shifts might have negative consequences such as dominance by non-native species and loss of biodiversity.

eBotanical Prints – October 2024

Twenty more books were added to my botanical print book collection in October - available for browsing on Internet Archive. These 20 books covered a range of botanical topics: berries, fruits, nuts, plants for sale as well as plants of particular places (Mexico, Korea, New Zealand). They were published between 1830 and 1942.

A new era of treating neurological diseases at the blood-brain-immune interface – Investigating the connection of neurological diseases and a toxic immune reaction caused by blood that leaks into the brain….in particular, how fibrid (a blood protein) is responsible for setting of this detrimental cascade.

Antifungal resistance is not getting nearly as much attention as antibiotic resistance – yet the risks to global health are just as serious – Just as with antibiotics for farm animals, tons of fungicides are used annually to protect crops, of which some work the same way as antifungals used in humans. And just as bacterial resistance develops…fungi develop resistance too. Combating drug-resistant fungal infections is a complex problem. An important factor is that diagnoses of infections are often delayed – if they are even diagnosed at all. Simple tests for fungal infections are rarely available.

Nikon Small World Contest Celebrates 50 Years of Photographic Excellence Under the Microscope – Great images….the natural world that we can see only with assistance…an art form too.

So Last Season: The Environmental Impact of Fast Fashion and Textile Waste Exports - The last ten years have seen a dramatic increase in the production of single-wear garments—which has contributed to an excess of textile waste and consequent health impacts for the individuals who work in the textile manufacturing industry. Every aspect of the creation of fast fashion garments is unsustainable, from the creation of plastic-derived textiles to the construction of pieces by underpaid and overworked exploited laborers. Up to half of American textile waste is shipped to nations overseas. Adopting more sustainable wardrobe practices not only helps us move away from fast fashion, but also significantly lowers our individual carbon footprints and waste production.

Plastic pollution harms - Nano- and microplastic particles (NMP) are increasingly polluting urban and rural landscapes, where bees and other beneficial insects encounter them… it can damage their organs and cause changes in their behavior, preventing them from properly performing ecosystem services such as pollination and pest control.

British Ecological Society Photo Contest Celebrates the Breadth and Beauty of the World’s Biodiversity – I liked the variety of selections in this photo contest.

Introducing Six Steps to Calm: Our science-backed, stress-busting email course – From BBC…I subscribed…plan to take the course!

Your diet can change your immune system — here’s how - There is still much more work to do to unpick the effects of specific diets on the immune systems of those with different health conditions. However, a growing group of immunologists are optimistic that the mechanistic insights they are uncovering are the first steps towards personalized diets for a range of medical conditions.

US air pollution monitoring network has gaps in coverage - Most of the harmful effects from outdoor air pollution in the U.S. are linked to inhalation of fine particulate matter (PM). These suspended particles, like soot or liquid aerosol droplets, are smaller than 2.5 micrometers in diameter, garnering the designation PM2.5. In February 2024, to better protect Americans from health burdens caused by inhaling particles, the EPA adopted a more stringent standard for PM2.5. The EPA tracks compliance with air pollution standards through a network of about 1,000 costly and highly accurate monitoring stations placed in cities and towns nationwide. People of color and people with low socioeconomic status living in the U.S have fewer monitoring stations than other areas to measure air pollutants, meaning they may not be fully protected by the tighter air pollution standards.

Researchers Parse the Future of Plankton in an Ever-Warmer World - Climate change is hitting our oceans hard, making them warmer and more acidic, while radically altering currents. The outlook for plankton is mixed. As the planet warms, the diversity of the menagerie in many spots is increasing. But certain species are losing out, including big juicy plankton thought to be important for food webs and carbon sequestration. And, in the long term, plankton numbers may plummet as climate change starves them of nutrients. Meanwhile research continues: which plankton species are where but also exactly when, since shifts in bloom timing can also have big knock-on effects for fisheries. And the viruses that attack plankton seem to be on the rise as waters warm — another factor with as-yet unknown consequences.

Life Histories of North American Birds

The 6 early volumes of Arthur Cleveland Bent’s 23 volume work, Life Histories of North American Birds are available on Internet Archive. The work was published from 1919-1968…the later volumes completed posthumously after his death in 1954. The volumes available are from before 1930.

Bent evidently traveled extensively and interacted with 100s of people to compile the histories…quite an undertaking – more so since it was done before the computers! He started the work when he was 44 years old and spent the 44 remaining years of his life working on it. The work includes numerous photographs; I provide two from each book below but there are many more – well worth browsing these volumes - and the text is interesting as well.

Landslides, Thousands Of Downed Trees, Undercut Roads Along Blue Ridge Parkway – Lots of repairs for the National Park Service after Hurricane Helene.

In Search of Microbes That Weave Colors into Moroccan Carpets - A scientist’s quest for microbes that produce purple pigments led to the vibrant world of natural dyes for women in the Atlas Mountain region of Morocco creating sought after traditional woven carpets…it’s a great intersection of biology and traditional artistry! The findings are compiled into a 48-page open-source guidebook, also translated into English, which described their project, introduced microbial dyeing, and catalogued recipes for plant dyes.

Dementia diagnostic markers change with time of day - Biomarker levels (p-tau217) were at their lowest in the morning when participants woke and highest in the evening.

Great Lakes Water Quality Project Seeks to Restore Coastal Vegetation - Returning certain croplands to perennial vegetation to reduce runoff and limit erosion.

'A warmer, sicker world': Mosquitoes carrying deadly diseases are on an unstoppable march across the US - West Nile virus, Eastern equine encephalitis (EEE), malaria and dengue…The mosquitoes that carry these diseases are thriving in a warming world.

Extinct Volcanoes Could Be Source of Key Metals Needed for Clean Tech - Rare-earths lurking under extinct volcanoes may be easier to extract. The iron-rich magma that formed some extinct volcanoes would be up to 100 times more efficient at concentrating rare-earths than the magma found in active volcanoes today. By one estimate, demand for rare-earths is set to grow fivefold by the end of this decade so finding them closer to home could contribute to more rapid conversion to clean technologies.

See Newly Discovered Nazca Drawings That Depict Llamas, Human Sacrifices and More - With the help of artificial intelligence, researchers have found hundreds of ancient artworks carved into the pebbled ground of Peru’s Nazca Desert in 6 months compared to 430 found between 1927 up to before the use of AI.

Fredrik Robert Martin and Oriental Carpets

A History of Oriental Carpets was produced by Fredrik Robert Martin based on his collection experiences in the late 1800s and early 1900s. Its three volumes are well-illustrated and easy to browse although I found myself wanting to zoom in on a lot of the images!

Missouri Master Naturalist Field Trip (1)

Last weekend was probably the best of the Missouri Master Naturalist training field trips. The location was a privately own mixed forest, old fields, a cemetery and a creek: a place with history and almost 30 years of restoration work. It was a scenic drive of about 20 miles from my house…quickly going to 2 lane road…then a road without a center stripe….and then a single lane gravel round with some low vegetation in the center which I heard brushing on the bottom of my car.  

There were three rotations with lunch between the second and third ones. The day started out cool but was close to 80 by the time we ended so I was pleased to do the walking rotation first. It was focused on native trees and plants…and fungi.

There were lots of black walnuts on the ground….and looking up…it was easy to see which tree was producing them since there were still nuts on the trees.

As we walked along the road – there were several fungi to see on rotting logs.

There were familiar leaves and bark….and heart shaped leaves of wild ginger. The leaves on the ground were brown but there was color in the leaves still on the trees.

The millstone from the old mill (broken into two pieces) was near the entrance to the cemetery…brought there when it was found in the creek. Both areas are reminders of the history of the place as much as a place along the creek we were told about over lunch where many arrowheads had been found (a place there they were made over many hundreds of years before Europeans arrived).

Our guide for fungi had brought some other specimens found elsewhere to share with us since the drought had reduced what we would see otherwise on our walk.

The hour past very quickly and we headed back to our next rotation which was journaling…I’ll post about that tomorrow.  

Gleanings of the Week Ending October 12, 2024

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

Who Was Buried in Spain’s Megalithic Necropolis of Panoría? - More women than men were buried in Panoria, where human remains were interred in collective burials between 4,100 and 5,600 years ago.

On Navajo Lands, Ancient Ways Are Restoring the Parched Earth - Traditional rock and stick structures, similar to those used by Native peoples long before Europeans arrived on the continent, are not only delivering water to crops they are also restoring the watershed and those of neighbors, helping to sequester carbon, and reviving this high-desert ecosystem…. an opportunity to begin developing localized food economies.

Megadiverse flowering plant family on isolated islands – A high number of evolutionary events -- occurred in the aster family (daisies, sunflowers, and asters) within relatively short time periods on many islands worldwide.

Why is Mount Everest so big? New research highlights a rogue river – but deeper forces are at work - Everest is around 250m taller than the other great peaks of the Himalayas. It is also growing by about 2mm each year – roughly twice as fast as it has been growing on average over the long term. The Arun river’s course changed around 90,000 years ago, eroding away rock that was weighing Everest down – and the mountain has bounced up in response, by somewhere between 15 and 50m. However, the “fundamental cause” of the peak’s size is the tectonic processes that create mountains.

Researchers Grow an Extinct Plant From a 1,000-Year-Old Seed - Israeli researchers have grown the seed of a previously unknown species of flowering plant into a mature tree. In the late 1980s, archaeologists excavating caves in the northern Judean desert discovered a well-preserved but mysterious seed that had likely been carried there by animals. The seed could be dated to between 993 C.E. and 1202 C.E. and that it was a unique member of the commiphora family, a flowering plant known for its aromatic resins. Chemical analysis of the leaves shows an abundance of medical properties in the leaves, and its lack of fragrance matches descriptions of the tsori in the Bible.

Rare and Elusive Australian Bird, Once Thought Extinct for 100 Years, Discovered by Indigenous Rangers and Scientists – Night parrots are generally difficult to detect—a fact that has been long recorded in Indigenous culture. The elusive species creates tunnels and nests in dense spinifex bushes and emerges at night to forage for seeds.

5 things to know from this week’s big report on cannabis - A new report from the National Academies of Sciences, Engineering and Medicine finds the disconnect between the states and the federal government is leading to fragmented policies, and risks to the public. 5 takeaways:

  1. People consume cannabis more regularly than alcohol in the U.S.

  2. Weed and vapes can be super potent and that’s not always disclosed

  3. You can get psychoactive hemp products even in states where cannabis is illegal

  4. Research on cannabis is stifled

  5. Cannabis can be dangerous, but people hear more about its benefits than risks

Biodiversity Becoming a Top Priority - A survey of 300 landscape architects, designers, and landscape architecture educators in the U.S. found that 96 percent of landscape architects are familiar with the impacts of the biodiversity crisis. 45 percent have made biodiversity conservation a top priority of their practice and another 41 percent consider biodiversity as part of their organization’s environmental ethos.

Medical imaging breakthrough could transform cancer and arthritis diagnosis - A new hand-held scanner developed by University College London researchers can generate highly detailed 3D photoacoustic images in just seconds, paving the way for their use in a clinical setting for the first time and offering the potential for earlier disease diagnosis (cancer, cardiovascular disease, and arthritis). What a boon if this could become the new standard…avoiding waiting for an imaging appointment, having to sit still for a long time, and higher cost of current technology!

Incredible Winners of the 2024 Natural Landscape Photography Awards – Couldn’t resist this collection of beautiful images to finish off the gleanings for this week.

Robert Ellice Mack’s Children of the late 1800s

The week’s eBooks are full of illustrations of children – mostly outdoors. They are probably somewhat idealized but are a window into the view people had of what children should be doing in the late 1800s. Certainly children were outdoors more often then than most children are today.

All round the clock

Sweet nature and other poems, with illustrations

Robert Ellice Mack was the editor of the books – selecting poem written by others and illustrations from several artists. There are other books from him that have been digitized; a good list is on University of Pennsylvania’s Online Books Page for him.
