How Britain's taste for tea may have been a life saver - The explosion of tea as an everyman's drink in late 1700s England saved many lives - the simple practice of boiling water for tea, in an era before people understood that illness could be caused by water-borne pathogens, may have been enough to keep many from an early grave. Sometimes people's existing behaviors can make more of a difference to their health than an explicit intervention might.

Carbon-Based Paleolithic Paintings Found in France - The carbon-based drawings were detected with visible light and infrared photography, X-ray fluorescence, and spectroscopy underneath previously known images. The discovery could allow for precise radiocarbon dating of the artwork. Most of the Paleolithic paintings in the more than 200 caves in the region were made with iron and manganese oxides, which cannot be directly dated with radiocarbon dating technologies.

Winners of the 2023 International Landscape Photographer of the Year Contest – Wonderful views. I wish more of them were annotated (where they were taken…comments from the photographer, etc.). One of my favorites was the Winner for Snow and Ice by Thomas Vijayan of Canada.

Which zoo animals are most active in winter and what times are best to see them? – Author commenting about zoos in the UK…but most of the comments are relevant to zoos in the US too. I particularly enjoyed the last recommendation – going to the Reptile House to warm up! My daughter gave us a membership to the local zoo for Christmas…and we’ll probably bundle up and go soon (but not while the weather is in the 20s)!

Photos of the Week – December 24, 2023 from the Prairie Ecologist – Great reminders that there are interesting subjects for nature photography in winter.

103-Year-Old Artificial Christmas Tree Sells for Over $4,000 – A sliver of history: The tree originally belonged to Dorothy Grant, whose family purchased it for their Leicestershire, England, home in 1920. When she first saw it, the 8-year-old girl was “wildly excited.” She decorated its branches with cotton wool that resembled snow, as baubles were an “extravagance” at the time. Grant cherished the tree for the rest of her life. When she died at the age of 101 in 2014, her 84-year-old daughter, Shirley Hall, inherited it. She decided to part with it to honor her mother’s memory and to ensure it survives as a humble reminder of 1920s life—a boom-to-bust decade.

Photography In the National Parks: 2023 In Review – Rebecca Lawson’s favorite shots from 2023 from Yellowstone, Glacier, Mount Rainer, Lake Chelan, Yosemite, Death Valley, and Banff National Parks.

Honeycrisp, Cosmic Crisp usher in banner year for U.S. apples - Growers report that apple production in the United States hit levels in 2023 that had not been seen since the 2014-15 season. Washington State was the largest grower, producing some 90% of the nation's crop. Of all the varieties, Honeycrisp, Gala, Red Delicious, Granny Smith and Fuji make up 76% of the total apple holdings. The big winner this year was the Cosmic Crisp apple, which experienced a 41% year-over-year growth, with 9.5 million bushels harvested.

Millions of mysterious pits in the ocean decoded - Most of the depressions in the seafloor in the German Bight are created by porpoises and other animals in search of food, and then scoured out by bottom currents. The researchers showed that the marine mammals leave pits in the seafloor when they hunt for buried sand eels.

2023 was a year of big anniversaries – 20 years ago the space shuttle Columbia disintegrated over Texas…the Concorde made its final flight, 30 years ago the World Wide Web launched into the public domain, 50 years ago hip-hop began, 60 years ago March on Washington for Jobs and Freedom (“I have a dream” speech)…JFK assassinated, 75 years ago Israel declared independence, 80 years ago Casablanca opened, 150 years ago blue jeans patented.

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.

An elegant enigma – A shipwreck discovered 30 feet below the surface 15 years ago…what we know (and don’t know) about it after study of the 1,500 objects recovered including textiles in 4 chests. The name of the ship is still unknown but the construction indicates it was a Dutch trader constructed around 1645 and sank around 1660.

At Peru temple site, archaeologists explore 3,000-year-old 'condor's passageway' – A 3,000 year old sealed corridor in a massive temple complex built by the ancient Chavin culture.

Does Nature Need a Trigger Warning? – A thought provoking post. Predators must be part of our conservation actions…and need to be valued as they are rather than simplistically.

Two-Hundred Years of Written Observations of Kīlauea's Summit Activity – On August 1, 1823, an English missionary visited the summit and published his observations (I found the book online -available on Internet Archive…Chapter 6 begins on page 121…image below). Mark Twain visited in 1866 and trekked across the caldera floor to Halema’uma’u, watching “a heaving sea of molten fire of seemingly limitless extent.” There are several links in the article that are worth following. My favorite is the USGS Views of a Century of Activity at Kilauea Caldera – A Visual Essay.

How Texas is racing to thwart the heat  - Unfortunately, planning for heat is not as well-developed in the US as planning for other hazards like flooding so many cities are scrambling to take proactive measures to cool their streets down and protect people from the dangerous impacts of overheating. In urban heat islands, temperatures can be up to 20 degrees Fahrenheit hotter than less populated areas. Austin, TX has a climate resilience plan that includes strengthening emergency response and future-proofing new facilities and infrastructure. It also developed an urban forest canopy for the city to ensure cool outdoor spaces. The city has now applied for a United States Department of Agriculture (USDA) grant to plant more trees after finding the tree canopy coverage was helping Austin to adapt to hotter temperatures. In 2021, San Antonio became the first city in Texas to participate in a pilot project to lower pavement temperatures by applying a coat of paint that reflects the sun's rays. I was disappointed that other large cities in Texas (like Dallas and Houston) were not mentioned in the article. My impression of Dallas is that there is a lot of concrete.

Detecting spoiled foods with LEDs – A potential improvement in non-invasive monitoring of fruit and vegetable freshness.

Joshua trees are dying. This new legislation hopes to tackle that – A compromise law…sets up a conservation fund and requires the state to develop a conservation plan and companies to obtain a permit from the state to cut down or relocate existing trees.

The looming 840,000 ton waste problem that isn't single-use plastics – Carbon and glass fiber composites used in wind turbine blades, hydrogen tanks, airplanes, yachts, construction, and car manufacturing. "This is a huge opportunity," said Dr Wei. "And not only because various modes of recycling are cost-effective and minimally impactful on the environment. In an era of mounting supply chain disruptions, local recycled products can provide a more immediate product when compared to imports and create a burgeoning advanced manufacturing industry."

National Park Visitors Warned to Be "Prepared to Survive" Heat – My husband and I have avoided trips to the western national parks in summer since the 1980s…primarily to avoid crowds but now ‘excessive heat’ is part of our rationale too.

The ocean's color is changing as a consequence of climate change – The color shifts have occurred in 56% of the world’s ocean based on analysis of data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite, which has been monitoring ocean color for 21 years. Tropical oceans have become steadily greener. Changes in color reflect changes in plankton communities, that will impact everything that feeds on plankton. It will also change how much the ocean will take up carbon, because different types of plankton have different abilities to do that.

See the Breathtaking Ocean Life Found at Deep-Sea Vents – A short video is included…worth watching.

Exploring the underground connection between trees – Trees, fungi, and other organisms…all interdependent but not guided by a common purpose.

Vibrant Fungi Photos Capture the Beauty of Nature and Nostalgic Memories of Foraging for Mushrooms – Images to savor.

Traces of a Neolithic Road Discovered in the Adriatic Sea – Stacked stone slabs that connected a settlement to a man-made island…now under water.

Shifting sand spits – Gauging climate change in a high-altitude watershed.

Air pollution from oil and gas production responsible for $77 billion in annual US health damages, contributes to thousands of early deaths, childhood asthma cases nationwide – Another reason to dramatically reduce the burning of fossil fuels. It’s not just about climate change.

An ‘Epidemic’ of Loneliness Threatens Health of Americans – A mounting problem. Social disconnection has multiple types of cost: economic, health, poorer academic achievement/work performance.

The ocean is hotter than ever: what happens next? – Probably more extreme weather and marine heatwaves…problems for marine life from corals to whales.

Cleanup of inactive Gulf of Mexico wells estimated at $30 billion – The life cycle costs of the fossil fuel industry are much greater than we’ve ever paid (i.e. we haven’t generally paid for clean up costs as part of the cost of fossil fuel based products)…the bill will eventually have to be paid.

Photography In the National Parks: The Invitation of An Intimate Composition – Good tips for more than National Parks! It’s a special kind of landscape photography!

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.

A Watershed Moment: Key Findings About Potential Drinking Water Contamination – The sources of contamination are varied….but the list of primary sources is relatively short.

Better residents’ health after switch to electric buses – A study from Sweden. Improved health is a benefit of electrification of transportation!

Should people get rid of their yards? – Somewhat depressing conclusion: “Most people would rather make an aesthetic choice with their lawns than an environmental one.” My plan is not to eliminate the yard in my new house but to minimize it over time with the addition of bushes along the fence and extending beds around trees and around the house.

We talk the fastest growing green jobs with LinkedIn Sr. Editor – The “job vs the environment” is changing. The “green economy’s ability to expand job opportunities is too significant to ignore.” This growth in green jobs is like the 1970s for computer related jobs – a lot of new types of jobs and many of them will extend for the duration of a career starting now.

Discover the Microscopic Wonders of Olympus’ 2021 Image of the Year Awards – Taken with light microscopes…lots of finesse preparing the specimens.

Known to be toxic for a century, lead still poisons thousands of Midwestern kids – Two things I learned from this article about the state I am moving to: Missouri is one of the four states in the Midwest that is struggling to alleviate lead poisoning in children…and it is the number one producer of lead in the US. Hope they are making progress.

Top 25 birds of the week: terrestrial birds – Always enjoy the bird photographs! This group includes a roadrunner….a bird I always associate with Texas but the photograph was taken in California!

Tests indicate bronze age daggers had a practical purpose – Evidently the daggers were thought to be ceremonial objects prior to this analysis.

Should we be eating three meals a day? – The number of meals may not be as important as consistency….and giving the body a long enough ‘fast’ time to rest.

The Great Barrier Reef through Time – Landsat Images used to illustrate recent research on the growth of the reefs as the ocean changes. Evidently the reef has been more resilient to past sea-level and temperature fluctuations than previously thought….but increased sediment input has been a bigger problem.

Virologists Identify More Than 5,000 New Viruses in the Ocean – Another indication that we still have a lot to learn about life on our planet.

Top 25 birds of the week: Bird Habitats! – Beautiful birds! I always enjoy seeing photographs…seeing birds I know and some I don’t!

The Jumping Slugs of the Pacific Northwest – A little different than the slugs I’ve seen. These have a vestigial shell on the top of their ‘hump.’ There was a new-to-me skeletal name in the article: slugs have a hydrostatic skeleton!

Aging clocks aim to predict how long you’ll live – Really? The value of the various aging clocks is still TBD.

Wildflower Fungi – This post was from the Master Naturalist group in Springfield MO. I am paying more attention now that I am moving to the area.

Deforestation drives climate change that harms remaining forest – Deforestation causes changes in a regions air temperature and precipitation…instigating changes in the whole region rather than just the part where the forest was removed.

Scientists Identify 50,000th Spider Species on Earth—but Thousands More Are Waiting to Be Discovered – It’s humbling to realize that there is so much about our world that we don’t know….have not discovered.

Amid Hopes and Fears, a plastic boom in Appalachia is on hold – Another sad trend in Appalachia…still hitching their future to fossil fuels. The jobs look good but the long-term jobs are few and the market for their products is not a positive one. Everyone wants to reduce single use plastics as much as possible.

Study suggests tree-filled spaces are more favorable to child development than paved or grassy surfaces – Playgrounds need more trees!

Germany’s Nature Society Crowns the 2022 Nature Photographer of the Year – The first picture is of a male kestrel. That caught my attention…and then I browsed the rest of the photos.

Philip Henry Gosse Books

/

Back in October, I enjoyed browsing 8 volumes published in the mid-1800s by Philip Henry Gosse available on Internet Archive. He was an active naturalist and popularizer of natural science with his ability to create appealing/accurate scientific illustrations for his books. I found out from Wikipedia’s biography of him that he was the inventor of the saltwater aquarium in early Victorian England too. Enjoy browsing a Gosse book or two or three…

A Year at the Shore (1865)

The Rotifera (or, wheel-animalcules) volume 1 and 2 (1889 assisting Charles Thomas Hudson)

Mapping out rest stops for migrating birds: New metric can help determine when birds fly over a site or stop to refuel or rest -- ScienceDaily – Stopover-to-passage ratio during migration research involves analysis of weather radar data collected since the 1990s…teasing out bird movement from precipitation! Results so far have included some surprises (and there are probably more to come as more of the historical data is processed and the processing becomes more and more sophisticated).

This Crocodile Dad Gives Over 100 of His Kids a Lift – A large species (gharial) with a narrow snout…in India.

Top 25 birds of the week: November 2020 – Birds from around the world….so much beauty in the natural world to see…and try to protect.

Top Solar States Per Capita 2012 vs. 2020 — CleanTechnica Report and US Energy Dept. Aims For Affordable Solar Power – Two posts about solar power. The first article shows the growth since 2012. In states where there wasn’t much growth, I wondered if the utilities in the state or the state government posed barriers to solar power. It seems like the whole country  should be in the mode of getting out of the way or encouraging renewal energy. The second article was about community solar programs from DOE with a mission to ‘bring affordable solar power to every household in the US by 2025’ – a worthy goal but is there enough money in the pipe to do it? This is not a technical problem as much as ‘are we ready to just do it.’

Lullabies in any language relax babies -- ScienceDaily and Baby Bottles Can Shed Millions of Microplastic Particles: Study | The Scientist Magazine® - I’ve been thinking recently about how much things have changed since my daughter was a baby over 30 years ago. I had a lullaby tape (in English) that I played for her in the evenings (although when she got old enough to choose – she wanted soundtracks from Disney movies as often as the lullabies). Now – we’d have digital music playing (rathe than cassette tapes) and maybe there would be lullabies in different languages too. The second article is about some worrisome research and I hope that pediatricians are keeping up and advising parents on best approaches.

When Domestic Birds Go Wild – Chickens, turkeys, ducks, swans, guinea fowl, peacocks, ornamental pheasants, doves and pigeons, emus, and parrots.

Picturing Earth: Astronaut Photography In Focus – A video – just under 70 minutes….with good imagery and discussion.

The return of Europe’s largest beasts - BBC Future – Bison, wolves, and elk…will the agricultural sector of Europe learn to cope with the big herbivores…and a predator?

As Waters Warm, Ocean Heatwaves Are Growing More Severe - Yale E360 – It’s easier for us to notice the heatwaves on land…but the ocean is taking the bulk of the increased heat on the planet and research on marine heatwaves is just beginning. The precise definition of the phenomenon was only proposed in 2016.  

See the World in Detail Thanks to the Close Up Photographer of the Year – Ending the gleanings list this week with some eye candy….enjoy the visual treat.

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.

Utah’s arches continue to whisper their secrets - GeoSpace - AGU Blogosphere – A study to measure arches to hone 3-D models from the Geohazards Research Group at Universe of Utah. The 30 second video of the model showing how Moonshine Arch moves is worth viewing.

Will the world be quieter after the pandemic? - BBC Future – I know I appreciate having a quieter environment; it’s an aspect of the pandemic that has been positive. The quiet is one of the things I like about my Prius Prime when it is in EV mode. Maybe some of the new norm will involve choices to maintain, as much as we can, the quiet.

Exposure to air pollution impairs cellular energy metabolism -- ScienceDaily – A study from Finland – exploring how particulates impact the olfactory mucosa (a neural tissue located at the upper part of the nasal cavity…the first line of defense against inhaled agents). As I read the article, I wondered if this is the tissue impacted my COVID-19 in people that lose their sense of smell when infected….and also, does wearing a mask filter enough particles to give the tissue a break from other air pollutants.

Renovations Reveal Rare Maya Murals Hidden in Guatemalan Home | Smart News | Smithsonian Magazine – From a colonial home in a mountain village.

Bird feeding helps females more than males -- ScienceDaily – The female cardinals are at my bird feeder much more frequently that the males in both winter and summer. This study doesn’t really point to a reason for that. I’ve always thought that other than the males dominance getting food first….the females might need more food at certain times….when they are laying eggs, for example.

London Foxes Show Early Signs of Self-Domestication | Smart News | Smithsonian Magazine – “Domestication syndrome” – shorter snout and smaller brain.

Painted Vault Revealed at Villa Near Pompeii - Archaeology Magazine – There are new discoveries because they are excavating a part that has not been studied before.

Marine Biologist Braves Cold Water to Photograph Little Known Sea Creatures – Creatures of the ocean….many so delicate they can’t be studied in a lab. Alexander Semenov is a marine biologist and photographer working like a 19th century naturalist, but with 21st century technologies.

Plot Brewing To Blanket US In Solar Panels + Pollinator-Friendly Plants – A beginning…. building hope via steps in the right direction. This article coincided with the MACCEC conference earlier this week. I ended the week more optimistic that the ball is in motion for many ‘drawdown’ actions.

Fish Eggs Can Survive a Journey Through Both Ends of a Duck – The study in this article was done with common carp and Prussian carp…. but what about other invasive species. If most types of fish eggs can survive the duck’s gut - it is bad news for efforts to stop the spread of invasive fish species.

Unique Activities for Yesterday:

Thinking about the first women in my family that could have voted. Women have had the right to vote in the US since 1920 – we’re celebrating 100 years this year. My sister and I have been talking about our great-grandmothers (and maybe the great-great grandmothers too). It’s interesting to think about what it was like in 1920 in our family; they were all citizens by then…although one side of the family were immigrants or children of immigrants.

We wondered if their relationship to immigration and obtaining citizenship would have made it more likely that they would have voted. One of them was divorced with her children teenagers or older; she was educated in Europe before she immigrated. Did her oldest son go with her to vote? The other great-grandmother might have voted as well; she had 3 daughters in 1920 with the youngest being 8 years old (there would be one more after 1920) and they lived on a farm…but went into town often enough. My grandparents from that side of the family always voted, so there’s a reasonable chance that their mothers did to.

One of the things I learned during the recent conversations, is that the grandparents on the other side of the family hosted the local polling place in their garage in the 1940s! That’s an indication that voting was important to them and that could have been passed down from their parents.  One of those great-grandmothers ran a boarding house (around 1920) so she was aware of things going on in town and would have had easier access to the polling place. She insisted that her daughter finish high school a few years later which might indicate that she was attune to the changing role of women more broadly.

I like to think that maybe all 4 of my great-grandmothers voted in 1920…their first opportunity to do so.

Top 25 birds of the week: Birds in Flowers! - Wild Bird Revolution – Birds and flowers…probably my favorite group of  the ‘top 25.’

Molecules that reduce 'bad' gut bacteria reverse narrowing of arteries in animal study: Promoting a healthy gut microbiome may be a powerful strategy for lowering cholesterol and other heart attack risk factors -- ScienceDaily – Eating differently could help…but eventually we might take ‘medication’ that helps us reduce or eliminate the unhealthy gut bacteria even if we are not as mindful about what we eat.

Study Suggests Human Relatives Were Genetically Compatible - Archaeology Magazine – Using genetic distance values to predict that hybrid offspring of Neanderthal and Denisovan would have been health and fertile…and thus explaining why modern humans have traces of their DNA.

Travelling for pleasure: a brief history of tourism – A little history lesson of travel…..more of a virtual experience right now rather than planning to travel anytime soon.

Unique activities for yesterday:

Still life. The petals are falling off the bouquet that I bought at the grocery store over 2 weeks ago. I like the curves of the petals against the pattern of the scarf I have on the tabletop.

Eggs with garlic scape. One of my favorite ways to have eggs….and only available during the early weeks of the CSA. This ‘first time for the year’ was for lunch with some left-over corn muffins I made a few days ago. Dessert…a few hours later was the last of the strawberries I got at the CSA.

Just being in the outdoors. I ate breakfast and lunch out on the deck. It felt a little cool for breakfast – made worst by the very cold breakfast smoothie - and then warmer and muggy by lunchtime. This month I have been intentionally spending more time outside and broadening what I am doing there…it is not just about lawn work or hiking or nature photography…I am reading and interacting with the cat and writing blog posts (i.e. making the covered part of the deck a ‘room’ of our house). The point of it all is to just be outdoors. The only negative would be if I was allergic to something, but it seems that most of the pollen that bothers me is not around right now. All I am experiencing is the positive.

Top 25 Wild Bird Photographs of the Week: Waterbirds and Camouflage and Forests and Birds in Pairs – Starting out this week’s list with some bird pictures….catching up the backlog

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

First Global Map of Saturn's Moon Titan Reveals Secrets of Earth's 'Deranged' Twin | Smart News | Smithsonian – There are plains, sand dunes, mountains, labyrinthine valleys…and lakes of methane.

'Self-cleaning' concrete could keep buildings looking new -- ScienceDaily – Maybe a new building material…but can it be made in a ‘green’ way?

Everything You’ve Ever Wanted to Know About Turkeys – I’m just catching up on some reading…this would have been more appropriate for the Thanksgiving week gleanings…but better late that never. Turkeys are interesting birds!

Air Pollution Tied to Brain Cancer: Study | The Scientist Magazine® - Combustion-related nanoparticles can reach our brain! The concentrations of these particles in highly polluted areas are also causing other health related problems as well. For example, the air pollution in Kabul, Afghanistan may be causing more deaths than war in that area

Owling: A Field Guide to Finding Winter Owls – Seen any owls? They are often easier to hear than see.

Slideshow: Images from The World Beneath | The Scientist Magazine® - A few pictures from a new book about sea creatures and coral reefs. Lots of vibrant color and camouflage.

Eating in sync with biological clock could replace problematic diabetes treatment: An early-morning, carb-filled meal improves glycemic control among diabetics -- ScienceDaily – We are shifting our meals…largest one at midday…smallest one at night. If we eat a high carb meal it will be at breakfast. I had gingerbread cake this morning!
