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.

08/15/2026 BBC  Future The controversial story of the North American raccoons wreaking havoc in Germany - One morning in April 1934, the records show, the animals were released from two crates to the south side of Lake Edersee near Vöhl, around 50km (30 miles) to the south-west of Kassel. This population grew and grew. Today, Kassel has been called the "raccoon capital of Europe", with an estimated urban population of around 30,000 of the animals.    

08/21/2026 Smithsonian Magazine An ‘Extremely Rare’ Half-Male, Half-Female Bird Temporarily Took Up Residence Outside of Chicago - An eye-catching bobolink with both male and female characteristics temporarily took up residence at a nature preserve just west of Chicago. The bobolink is what’s known as a “bilateral gynandromorph.” Because of a genetic anomaly, the right side of its body is male while the left side is female, with a straight vertical line dividing the two halves. It’s believed to be the first documented gynandromorphic bobolink. The bird behaved like a male, eventually wooing a mate and raising fledglings.

08/21/2026 Science Daily Archaeologists discover mysterious 400-year-old Indigenous pot in Florida - The pot was compact enough to fit in a palm, with a simple rim, a smooth dull gray surface, and no decoration. Its original purpose is unknown, as is the number of people who may have used it. What archaeologists do know is that the vessel survived for centuries underground

08/21/2026 Artnet Why Louis Comfort Tiffany Still Dazzles Collectors - Louis Comfort Tiffany‘s lamps are coveted and his stained glass is celebrated, but the artist behind the famous brand has remained stubbornly in the shadows. Two new exhibitions aim to throw the spotlight on his full talents.

08/21/2026 Clean Technica Sunrun Shifts Away from Affiliates to Direct Sales - Sunrun has been the #1 rooftop solar power installed in the United States for several years now.Sunrun installed 19,793 subscriber systems in the second quarter of this year, which is an amazingly high number. However, the bad news is that this was down 31% from Q2 2025. Yikes. On the plus side, the company had a higher percentage of its solar power systems get energy storage add-ons than ever before — a whopping 74%. That’s up from 70% in Q2 2025. Sunrun has surpassed 266,000 total storage systems installed, accounting for 4.6 GWh of capacity. That includes the 332 MWh installed last quarter.

08/19/2026 NASA Elephant Butte Reservoir Runs Low - Elephant Butte Reservoir, the largest reservoir in New Mexico, is at its lowest level since 1971. My husband and I took a birding field trip in a boat on the reservoir in November 2016; they told us it was low then…and I wonder what has happened to the birds (pelicans, grebes, coots, and cormorants) that won’t find much water when they return to the area this fall.

08/19/2026 The Prairie Ecologist The Notorious (and other) Visitors to Our New Prairie Garden – Lots to photograph in a native plant garden!

08/19/2026 Planetizen To guarantee residents fresh water, Tijuana looks to the sea - The project is expected to produce 2,200 liters of fresh water per second — about 190,000 cubic meters a day — and increase available freshwater in the region by 45%. Construction is set to begin on Aug. 18, one day after signing the contract but nearly three weeks after the project's intended start date of Aug. 1.  It is expected to be complete in 2029.

08/18/2026 Yale Environment 360 Collapse of Atlantic Currents Could Drive a Surge in Warming - A vast system of Atlantic currents appears to be weakening, and scientists say its collapse could lead to dramatic cooling in northern Europe. A new study suggests an additional risk: a surge in warming across the rest of the globe.

08/21/2026 BBC Future India is turning to ancient water systems as modern ones run dry - In recent years, India is increasingly looking to revive ancient water structures as a way to help address the country's looming water crisis. Baoris, or ancient stepwells – large scale tiers of carved stone with steps that descend into the water table, allowing access to groundwater – are the most striking. Thousands of disused subterranean stepwells, built from the 7th to the mid-19th Centuries, famously dot India's landscape. From New Delhi to Jodphur, dozens have been restored in recent years. Open traditional structures like stepwells do not escape evaporation completely, but by helping to move water beyond reach of the Sun into aquifers they allow it to stay both cool and reachable by any well or handpump nearby.

Plastics Crisis – The Personal Economics of Less Plastics – Update

/

Last January I posted about what I had done over the later part of 2025 to reduce plastics around my house and the advantages we were observing. We are still benefiting from the investments I made without a lot of additional investments since January. I’ve notice that our grocery lists are generally shorter and we have less trash and recycle….and we aren’t feeling the full bite of inflation as much as I thought we would.

Trying to reduce plastic in all my purchases has encouraged more thoughtful purchasing. It slows me down enough to decide not to purchase something…realize that the item is not a ‘need’ and that I don’t really want it enough to purchase it. Identifying (and avoiding) ultra-processed food is another goal that seems to correlate with plastic reduction! What’s not to like about reduce costs and eating better at the same time.

I’ve refined some of my behaviors over the past few months that have reduced plastics further:

  • I have a collection of cleaned out/reused peanut butter (glass) jars that I use for making sugar water for my hummingbird feeder and am reusing the lovely green glass bottles (lemon juice) for storing filtered water in the refrigerator (or for the ice chest when we travel).

  • Our store has catsup in glass bottles again – and we have started purchasing it rather than the larger plastic bottles. It works well for us since we do not use it as often as we have previously.

  • I have enlarged my ‘favorite salad dressings’ to include honey – lemon….and am able to easily find honey in a glass jar and lemons in a bin without packaging at the store. I haven’t bought salad dressing since my original decision to avoid plastics in close contact with acidic or oily foods!

  • The net plastic is sometimes less or similar between fresh and frozen foods. I have started buying frozen broccoli, corn, and peppers/onions rather than fresh. They reduce prep time for stir fry and there is no wasted food (i.e. something going bad before I can use it). The plastic is probably not degrading into the food since it is cold! I never cook the frozen vegetables in the bag even if the bag advertises that it is OK to use it to steam the veggies in the microwave.

  • I had planned to use violets in salads this summer and it worked well. The cyclosporiasis outbreak is an added motivation for me to continue to use this green – although this late in the season the leaves are better cooked than raw.

  • The main area of investment now is clothes. I am gradually replacing things that  are 100% synthetic (i.e. plastic: polyester, rayon, nylon, etc.) with equivalent items that are 100% natural fibers or a blend that is dominated by natural fibers. It is unfortunate that Amazon searches tend to return synthetic items – overriding the search terms completely! Sometimes local stores have what I want….and I am checking their stock more frequently now.

Progress is slower now…but I am still enjoying discovering ways to reduce plastics in my life!

Plastics Crisis: Milk

/

My regular grocery store only had milk in plastic jugs and plastic lined cartons. That is not good since milk has enough fat to make the chemicals in the plastic more likely to leach into the milk. Recently by daughter noticed that there was an option of milk in glass bottles at her grocery store and I am trying it! There is a deposit on the glass bottle to encourage people to return them…and buy the milk again!

The milk is from a dairy located about an hour from Springfield MO. They use low temperature vat pasteurization; I read that many people with lactose intolerance can drink the milk without problems…and I am pleasantly surprised that it is true for me.  

While I don’t know the plastics that might be in the dairy processing, at least the packaging of the milk is in a reused glass bottle and the ability to drink it without taking a Lactaid is just another benefit. The only downside is that it is a bit more expensive; for me the benefits outweigh that expense.

Plastics Crisis – The Personal Economics of Less Plastics

/

I’ve been making changes over the past months to reduce plastic around my house enough that I am now thinking about the benefits we are observing.

Our transition to bar soaps for showers and hand-washing costs less than the myriad of plastic bottled products…and both my husband and I have noticed skin improvements (less itching, less dry skin).

My electric tea kettle (only glass or stainless surfaces touching the water) is better than I imaged it would be – much better for making tea than the old coffee maker (that had a lot of plastic parts). I discovered that our water has enough minerals that the tea kettle developed scale quickly; putting a little lemon juice in the water (i.e. acid) solved the problem. I am using tea bags that are supposedly free of plastic glue but am considering cutting them open and using the tea leaves only. The tea makes it easier for me to cut back on soft drinks too! From a cost standpoint it is about the same as buying a new coffee maker.

I replaced all my plastic leftover and storage containers for food with glass (even though they have plastic lids….I don’t overfill the containers so that food never touches the plastic). The food is preserved as well as before and I find myself also using the containers for some items I previously put in Ziplocs (i.e. plastic) – like cranberries I am freezing and carrots I am taking with me for snacks on road trips. When I can’t buy a veggie except in a plastic bag (like carrots), I am starting to put them in a glass container when I get home from the store with the idea that the longer the carrots are in the plastic bag, the more microplastics they have on/in them. I also like that the glass dries better in my dishwasher!

The Rorra water filter is working well for us. We use it for drinking and cooking and the water fountain for the cats. There is no reason for us to buy bottled water any more. Of course – the Rorra and replacement filters cost something, but we are comfortable with our water at this point.

We replaced the type of humidifier we had with ones that use evaporation rather than creating a mist. This winter our house has about the same humidity level but without the white dust (and microplastics) the mist humidifiers created. Our air purifiers rarely go into ‘high’ mode now whereas last year they did any time we had them on near a humidifier.

Even though I have cut back on soft drinks, I still drink them occasionally….but they are in cans rather than plastic bottles. We have very few plastic bottles in our recycle. We have stopped putting some plastics in recycle even though our curbside service accepts them since we are aware that the materials rarely get recycled; even the milk and soft drink bottles/jugs (which are the most frequently recycled plastics) often end up in landfills…so it is good that we simply buy less in those containers these days.

I have stopped buying salad dressing since it is almost always in a plastic bottle. I am making my own. My favorite right now is a lemon ginger vinaigrette! It costs less and I make only what I need at the time.

I am going to start buying olive oil in glass rather than plastic as soon as I use up what I have. It will be more expensive, but I use it slowly, so I don’t need to buy a large container. I might have to buy it somewhere other than my usual grocery store just as I do my lemon juice(in a glass bottle).

I am buying fruits and veggies that are not packaged when I can - which means that I don’t buy arugula like before. I skew toward cabbage and squash and peppers and cucumbers and broccoli. In the summer I’ll eat violet leaves from my yard! The apples and pears and lemons I buy are not packaged; I do buy organic oranges in a mesh bag because that is the only way they come (and I give my daughter half of them). I take them out of the packaging as soon as I get them home.

In summary – I’ve made some investments (Rorra, glass containers, tea kettle, humidifier, a ladle to replace a plastic one) that are working well for us. They were not too expensive, and they will last a long time. On a week-to-week basis – costs have probably gone down by a little – no plastic water bottles of water, body wash, or hand soap…and less soft drinks overall.

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

The maritime lions hunting seals on the beach - In Namibia, a group of desert lions have left their traditional hunting grounds for the Atlantic coast, to become the world's only maritime lions.

Progress on Africa’s ‘Great Green Wall’ Stalls as Seedlings Die Off - The African Union launched the project in 2007, planning to create a 10-mile-wide strip of trees that would stretch from coast to coast, across 11 countries in the Sahel. By stopping desertification, the project aimed to protect farmers, help shore up the supply of food, stem migration, and even fight extremism. But as of last year, the project was estimated to be only 30 percent complete.

The Red Sea that vanished and the catastrophic flood that brought it back - The Red Sea once vanished entirely, turning into a barren salt desert before being suddenly flooded by waters from the Indian Ocean 6.2 million years ago. The flood carved deep channels and restored marine life in less than 100,000 years. The Red Sea is a natural laboratory for understanding how oceans are born, how salt giants accumulate, and how climate and tectonics interact over millions of years.

Pumpkin: A favorite sign of fall, with a bit of shady history - When European settlers reached the present-day Americas, they encountered Indigenous people growing pumpkins — a useful source of food that's easy to grow and can be stored in cold weather. In precolonial times, Indigenous people in the Americas domesticated different types of these sort of pumpkin precursors at least six different times.

Egyptian Pharaoh’s Tomb Opens to the Public After 20-Year Restoration – Amenhotep III. The huge tomb is in a secluded part of the Valley of the Kings outside the southern city of Luxor and was in severe need of work following centuries of neglect. The tomb was discovered in 1799 whereupon its contents were looted. At its center, visitors today encounter the pharaoh’s giant granite sarcophagus lid, which is covered in hieroglyphics and was too heavy to be carried away.

New Solar Glass Cranks Up Lettuce Crop Yields by Almost 40% - The new solar glass (the performance of quantum dots integrated with passive solar glass) was field tested by researchers at the University of California – Davis. If the performance of lettuce is a bellwether for other crops.

The rise of ‘nightmare bacteria’: antimicrobial resistance in five charts - Antimicrobial resistance (AMR) is projected to cause 39 million deaths worldwide over the next 25 years. But global efforts to find treatments for drug-resistant infections are not going to plan. The reports show that the global antibiotic drug-development pipeline is facing a dual crisis: a scarcity of drugs in development and a lack of innovation in methods to fight drug-resistant bacteria. Awareness of this issue is increasing; however, it is still a silent pandemic with many deaths not being attributed to AMR.

A Search for the Cassia Crossbill, Idaho’s Endemic Bird - Searching for an endemic bird brings you fully immerses you in the complexity of the world. What might look like just another set of hills from the highway is revealed to be a habitat shaped by a lack of squirrels and abundant woodpeckers and thick pinecones. And that place offers you a glimpse of this special bird, one that exists only here, as if clinging to a lodgepole life raft in the desert.

Brain cancer that eats the skull stuns scientists - Glioblastoma isn’t confined to the brain—it erodes the skull and hijacks the immune system within skull marrow. The cancer opens channels that let inflammatory cells enter the brain, fueling its deadly progression. Even drugs meant to protect bones can make things worse, highlighting the need for therapies that target both brain and bone. The discovery reframes glioblastoma as a whole-body disease, not just a brain disorder.

Babies take a lesson from soldiers in the war against malaria - For years, the U.S. military has treated uniforms with insecticide to repel mosquitoes and the malaria they can transmit. In a rural part of western Uganda, 200 mothers with kids between 6 and 18 months got a permethrin-soaked baby wrap, while 200 others got a wrap just soaked in water. All participants got a brand-new treated bed net too. Over 6 months, 34 kids in the permethrin-wrap group tested positive for malaria, compared with 94 in the water-soaked wrap group. About 8.5% of babies had a mild rash in the treatment group compared with 6% in the control.

Plastics Crisis – Miscellaneous thoughts

/

There is a lot about microplastics in the news; I’ve added some of the articles to my Gleanings posts. Microplastics are an overwhelming challenge to every living thing…and thus an overwhelming challenge to us. It is hard to find truly effective means to do something about them – to reduce their prevalence in our lives and in our broader environment. The actions I have taken so far seem small but maybe they are a place to start….there need to be bigger actions to make a difference. In this post I in including some of my thoughts over the past few weeks…as I search for the path beyond changes I can make to reduce microplastics (somewhat) in my own life.

  • Plastics are not part of any heritage…they are too new for that. They are damaging our environment in ways that degrades our health slowly. By the time we think of plastics as part of our heritage, it might be too late to stop our decline as a species.  

  • It is time that we realize that there is a price for plastics’ convenience in our lives that we are just now beginning to pay.

  • Hotels use plastic glasses in their rooms now….wrapped in more plastic. Not that long ago they were glass. Ice buckets are plastic and there is a plastic bag liner. We assume that the plastic makes it ‘clean’ but is that true?

  • The plastic pots the small plants were purchased in were very flimsy. They cracked as I flexed them to get the plants out as I planted the seedlings into my yard. They are another source of single use plastic.

  • Spaghetti sauce is easy to find in glass jars…unlike a lot of other foods. It seems not that long ago that it was easy to find mustard and lemon juice in glass. Not anymore.

  • Why aren’t cosmetic companies advertising products that are free of microplastics/endocrine disruptors?

  • Why aren’t retailers demanding less plastic packaging particularly when it adds little or no value. For example: multiple plastic layers around larger packages of toilet paper, the plastic insert in tissue boxes that has to be removed before the cardboard can be recycled, and the little window in paper bags of cookies that makes that bag unrecyclable.

When I bring up microplastics in conversation, everyone seems somewhat aware of the problem, and many are as alarmed as I am. At the same time, everyone seems to be anxious but doesn’t know what to do. There appears to be no leadership from any level of government. Maybe the pervasiveness of microplastics puts them into a new category of issues that our modern cultures do not know how to address…and that is resulting in no action. Climate change is another such issue and the experience to date has been frustrating to everyone. Again – the default seems to be to forge ahead toward a dystopian future because the magnitude of the issue is too overwhelming.

Plastics Crisis: A continuing journey

/

The past few weeks have been very busy, and I haven’t had time report on my continuing journey.

I attended my first ‘show me less plastics’ bimonthly zoom meeting. Everyone on the call seemed to be in the same initial mode…trying to figure out how to move forward. The largest group was from St. Louis…some from Kansas City and Columbia. There was one other person from Springfield. I will continue to dial into the zoom meetings and use them as a forcing function for myself to have something to report!

CNN did an experiment with three of its reporters (in New York, London, and Hong Kong) wearing chemical-tracking wristbands to find out what kind of chemicals they are exposed to. The video report can be found online - https://www.cnn.com/2025/10/08/climate/video/chemical-monitoring-wristbands-climate-digvid although there is not a lot of detail…it does indicate that people in big cities are probably exposed to a lot of chemicals as they go about their daily lives.

Living near a smaller city (Springfield MO), I do track the air quality. I know that when it is not green, the PM2.5 pollutants are usually the pollutant that is high…and that is made of microplastics and associated chemicals. The air quality where I lived in Maryland (between Baltimore and DC) prior to moving to Springfield was yellow more frequently and, sometimes, even made it to the red level.  So – moving to Springfield probably has reduced my exposure somewhat.

When I had my annual checkup with my doctor, I brought up microplastic exposure and she acknowledged the issue…but didn’t have any specific recommendations about what to do aside from avoiding bottled water and looking hard at getting plastics out of the kitchen, particularly anything that is heated and contacts food.

I have reduced my soft drink consumption to almost zero (avoid plastic bottles) and am drinking more iced tea. But wait….coffee makers (that I was using to make tea) have a lot of plastics and there are plastic fibers in many filters (so they will hold up better) and some tea bags are glued together (a plastic). Obviously there is heat involved in making tea so I changed my process:

  • Old Pyrex measuring cup (it was my mother’s and the markings are almost worn off)

  • Cut open the tea bag and empty the contents into the water

  • Heat in the microwave

  • Strain the tea leaves with a metal strainer

It’s becoming a good routine….and I am aware that making tea is becoming a ritual rather than just a routine because of the old Pyrex. It could be almost as old as I am!

One thing I am noticing…my trash and recycle are trending downward…not as much in the bins. That’s a good thing!

Plastics crisis: Interactions with Food Manufacturers

/

I chose a product that I buy frequently – Lactaid 2% milk – and went through the process of figuring out how to contact the manufacturer to stress my concern about microplastics in food from plastic packaging.

I found their ‘contact us’ web page and used the ‘email us’ option intended for comments, questions, and feedback. They responded in less than 24 hours with a response pointing to what they were doing to increase the recycled plastic content in their packaging. I sent a second ‘email us’ that included their reference number for my previous comment emphasizing that I was interested in net reduction in plastic packaging because of the microplastics it adds to food…I wanted to buy their product in non-plastic packaging. I got the same response. I became uncertain that there was a person behind the response or simply an AI selected canned message that didn’t answer the question/comment. I got two survey forms (one for each use of the ‘email us’) and filled them out the same….that I was unsatisfied with the response.

(Update: I got a call based on the ‘unsatisfied’ feedback on the survey! Now I am more confident that my concern has been heard. I am not confident that they will move to non-plastic packaging for at least some of their produces…but I have given then a heads-up that there may begin to be a lot more people concerned about microplastics in our food. I’ll see if there is anything new on their packaging on their website in a month or so.)

I am not going to buy their product again and I’m not sure I want to buy any other milk either. I am considering returning to a calcium supplement as I did years ago and getting protein from other sources.

Taking another route:

Beyond Plastics has a letter from members for consolidation into a package for Coco-Cola, PepsiCo, and Nestle about their contribution to plastic pollution around the world. They sent a draft which I personalized and returned.

A second call came out from Beyond Plastics to contribute a letter to Coca-Cola specifically urging them to expand their successful El Paso refillable beverage system to every community rather than continuing to use plastic bottles.

The experience has been eye opening in the sense that it appears that food manufacturers are still relatively clueless about the growing awareness of microplastics in our environment and the news of the micro and nano plastics found in many parts of our body. It is no longer about forging ahead with plastic packaging…..it is about net reducing the plastics packaging for foods.

I always enjoy seeing Chihuly glass in museums and gardens…and enjoyed browsing this book available from Internet Archive with wonderful pictures of some of his work. It is my book of the week.

Glass is a material that is strong yet fragile, shaped when molten then rigid. It’s my favorite kind of 3-D art. The graceful curves and vibrant colors seen in this book are like a meditation prompt for me!

How gardening can help you live better for longer - In 2015, Norway became one of the first countries to create a national dementia care plan, which includes government-offered daycare services such as Inn på tunet – translated as "into the yard" – or care farms. Now, as researchers recognize the vast cognitive benefits of working on the land, more communities are integrating gardening into healthcare – treating all kinds of health needs through socially-prescribed activities in nature, or green prescriptions.

Chasing Unicorns: A Photographer’s Journey Documenting Rhino Conservation - Bringing the rhinos from one conservancy to another was a monumental effort. A photographer documented the work of conservationists and veterinarians.

Gilded-Age Tiffany Window Heads to Auction with Multimillion-Dollar Price Tag - With most surviving examples of Louis Comfort Tiffany’s mastery of mottled glass still affixed to the walls of churches or stately homes, purchasing opportunities are rare.

Pit Stops on the Monarch Flyway: Arkansas Partnership Benefits Pollinators - You just don’t see as many monarch butterflies as you used to. Researchers have documented that eastern populations of monarchs have declined by as much as 80 percent since the 1990s. A partnership in Arkansas is restoring pollinator habitat, providing those critical stops for butterflies to rest and feed. The habitat is also utilized by migratory songbirds and northern bobwhite, a popular gamebird that has seen significant declines.

Vitamin supplements slow down the progression of glaucoma - In glaucoma, the optic nerve is gradually damaged, leading to vision loss and, in the worst cases, blindness. High pressure in the eye drives the disease, and eye drops, laser treatment or surgery are therefore used to lower the pressure in the eye and thus slow down the disease. n experiments on mice and rats with glaucoma, the researchers gave supplements of the B vitamins B6, B9 and B12, as well as choline. This had a positive effect. A clinical trial has been started to see if the vitamins have the same impact in people.

Archaeologists Find a Cache of Ancient Murano Glass Off Bulgarian Coast - Underwater archaeologists in Burgas, Bulgaria have discovered over 100 glass objects dating back to the days of the Ottoman empire in the nation’s Chengene Skele bay. It is speculated that the glass artifacts fell from the cargo of a ship battered by a storm in the shallow, rocky area of the sea. Experts attribute the glass objects to Murano, a Venetian island still renowned today for its fine glassware, likely made in the late 16th and early 17th centuries.

Want the health benefits of strength training but not keen on the gym? Try ‘exercise snacking’ – Great idea!

Timing is everything: Study finds link between bowel movement frequency and overall health – The research showed that if stool sticks around too long in the gut, microbes use up all the available dietary fiber, which they ferment into beneficial short-chain fatty acids. After that, the ecosystem switches to fermentation of proteins, which produces several toxins that can make their way into the bloodstream. They showed that the microbial composition of study participants' gut microbiomes was a telltale sign of bowel movement frequency. Fiber-fermenting gut bacteria, often associated with health, appeared to thrive in a "Goldilocks zone" of bowel movement frequency, where people pooped between 1-2 times per day. However, bacteria associated with protein fermentation, or the upper gastrointestinal tract tended to be enriched in those with constipation or diarrhea, respectively.

Replacing Fuel Tax A Government Quandary - As the proportion of electric cars on the roads rise, what will fill the funding gap left by the loss of gasoline and diesel tax? One possibility is a road user charge (RUC).

Scientists Find an Underground Cave on the Moon That Could Shelter Future Explorers - Radar data from NASA’s Lunar Reconnaissance Orbiter (LRO) points to the presence of a cave beneath the moon’s surface. Such caves could serve as shelters for future human explorers, since they could protect astronauts from the moon’s hazardous surface environment. (Note – LRO was launched in 2009. My daughter, as an undergraduate, did some of the initial image calibration work!)

With CO2 Levels Rising, World’s Drylands Are Turning Green - Southeast Australia has been getting hotter and drier. Droughts have lengthened, and temperatures regularly soar above 95 degrees F (35 degrees C). Bush fires abound. But somehow, its woodlands keep growing. One of the more extreme and volatile ecosystems on the planet is defying meteorology and becoming greener. Long-term studies by University of California, Riverside in the Sonoran Desert show that shorter shrubs better adapted to less rainfall and higher temperatures are moving in at the expense of native plants, creating an impression of greening that marks an ecological breakdown.

Why Are Amphibians the Most Endangered Class of Animals? - Amphibians are the most endangered class of animals in the world, with 41% facing extinction. Climate change on its own would not be such an incredible threat if it weren’t for the toll it takes when combined with habitat loss, fragmentation and disease.

New solutions to keep drinking water safe as pesticide use skyrockets worldwide - A 62% rise in global pesticide use in the past 20 years has escalated fears that many of these chemicals could end up in our waterways, causing cancer. Powdered activated carbon (PAC) is currently used to remove organic pesticides from drinking water, but the process is costly, time consuming and not 100% effective. The researchers found that reducing the PAC particles from the existing commercial size of 38 μm (one millionth of a metre) to 6 μm, up to 75% less powder was needed to remove six common pesticides, achieving significant water treatment savings.

Huge! The Massive and Mystical Jordanian Monument to an Enigmatic People - The ancient city of Petra. Known as the “Rose City” for the warm pink blush of the sandstone cliffs it is carved out of, Petra was built by the enigmatic Nabateans. Built over two millennia ago, it was long lost to the shifting sands of Jordan’s desert until it was rediscovered by European travelers in the early 1800s.

Melting Sea Ice Is Making the Northwest Passage More Dangerous - Old, thick chunks of sea ice that tend to cluster near the North Pole are increasingly drifting southward toward Canada and into the path of ships. The younger, thinner ice that once held older ice in place is becoming scarcer as the region warms. For the cargo vessels, fishing boats, and cruise ships crossing the northwest passage, drifting chunks of old, thick sea ice pose a significant threat.

New Constitution Gardens (in Washington DC) Will Be a Biodiversity Mecca – Glad there are plans to improve the area. I always enjoyed it even though it was beginning to show its age in the 1990s and early 2000s when we lived in Maryland and visited with our young daughter.

Stunningly Preserved Ancient Roman Glassware Turns Up in a French Burial Site – Found during construction of a new housing development. I am always amazed at how durable a material we normally thing of as ‘breakable’ can be!

Cicada dual emergence brings chaos to the food chain - Cicada emergences can completely rewire a food web. For predators, these emergences are a huge boom in resources. It's basically like an all-you-can-eat buffet for the hungry predator. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities. Scientists have found that wild turkeys, for example, will capitalize on the bounty, leading to a wild turkey boom. However, caterpillars, usually preyed on by birds, were left off the dinner menu and their numbers more than doubled. This in turn led to damage to trees caused by out-of-check caterpillar populations. Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.

Earlier Springs Cause Problems for Birds - As climate change warms our planet, causing spring to arrive weeks earlier than it has historically, birds are struggling to keep up. It’s not just the green vegetation they miss, but the pulse of protein-rich insects many bird species consume on both their breeding grounds and their migratory stop-over points. Birds will still breed but not quite as successfully because food will be more limited. Instead of chicks hatching as insect populations boom, those chicks may catch the end of the insect pulse.

Why you should let insects eat your plants – I skew the additions to my yard toward native plants….and let whatever insects show up enjoy. My community sprays for mosquitos so there probably is some reduction of other insects because of that. But there are enough left to support a barn swallow (and other insect eating birds) flock in our community.

Quantifying U.S. health impacts from gas stoves - Even in bedrooms far from kitchens, concentrations of nitrogen oxide frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off. All the houses I’ve purchased as an adult, have had electric stoves/ovens except one and I only lived there for 3 years. But – in the 1950s and 1960s, my parents had gas stoves/ovens. Back then the houses were not as airtight as they are now so that might have reduced our exposure; my sisters and I never had asthma or other breathing problems, fortunately.

Inside the exquisite Tibetan monasteries salvaged from climate change – Built in the 1300s, the monasteries are impacted by a significant increase in the intensity of storms and rainfall across the region. Increased rainfall saturates the rammed-earth buildings, as moisture in the soil is drawn upward into the walls, leading to issues such as leaking roofs and rising damp. Local people have gained diverse skills, from reinforcing walls to crafting metal statues and restoring paintings. Over the past 20 years, a team of local Lobas trained by Western art conservationists have replaced the old, leaky roofs of the temples with round timbers, river stones, and local clay for waterproofing, and have restored the wall paintings, statues, sculpted pillars and the ceiling decorations, giving these centuries-old monuments a new life.

Possible Conch Shell Communication in Chaco Canyon Explored - The settlements of Chaco Canyon that spread around each sandstone great house fit into the sphere of sound produced by conch shell trumpet blasts; perhaps the settlements were designed to ensure that every resident could hear the notifications.

Out and About with Company

When my sister and brother-in-law were visiting – stopping for a few days at a RV park near us before they continued on their month long travels – we enjoyed the botanical gardens and the zoo, then decided on a less active day starting with brunch at my house (I made a ‘full oven’ of food: egg casserole, chunks of seasoned new potatoes, and pumpkin bread) followed by a walk around the Springfield Art Museum and then the Springfield Conservation Nature Center.

The art museum was opening their Art in Bloom event – with the fashion component being the main part available for viewing. My favorite was the creation that was inspired by the hallway long tilted sky – probably my favorite piece in the museum!

Of course, there were plenty of other things to enjoy in the museum – other fashion and art works. I’ve picked some of my favorite views from the pictures it took.

Then we were off to the nature center…not for a hike (one of my guests was having back problems) but for the center itself. The turtle tank was being renovated so there were two large snapping turtles in a tank that was too small for them long term but offered views from two sides. It was a great photographic opportunity.

And then they headed off to prepare for the next leg of their trip.

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.

Restored Glass Negatives Capture Daily Life in 19th-Century New England – Photographs taken from the 1860s to 1930s….Massachusetts…different photographers.

As Temperatures Rise, Dengue Fever Spreads and Cases Rise – The mosquitos that carry dengue viruses are extending their range. There were 0.5 million cases in 2000…5.2 million in 2019. In recent years, dengue has popped up in places it had never been seen, including Afghanistan, parts of Southern Europe, and, this year, Chad. An additional 2 billion people would be at risk of dengue exposure by 2080, compared to 2015. Areas unfamiliar with dengue may be hard hit even if case numbers aren’t high as people won’t have immunity from previous exposure to the virus, and public health systems may not be strong enough to cope with dengue outbreaks.

The World’s Largest Iceberg Is Drifting Three Miles Into the Ocean Each Day - The world’s largest iceberg, which had been grounded on the seafloor since the mid-1980s, is moving away from Antarctica and picking up speed. It could disrupt the foraging of seals, penguins and other seabirds. Called A23a, the iceberg measures around 1,500 square miles—more than 20 times the size of Washington, D.C.—and it’s roughly 1,300 feet thick, making it two and one-third times the height of the Washington Monument. It weighs nearly one trillion metric tons.

Landscape Photography Awards Rewards Authenticity in Photography – My favorite was “Little Leaves”….maybe because it didn’t have time to see a lot with fall foliage this year.

Expansive Alexander Calder Exhibition Opens in Seattle – Take a look at the museum’s site for the exhibit at well.

Bird Photography Contest Celebrates the Unique Diversity of Australia’s Wildlife - Nine winners were singled out for their work, rising above more than 6,000 images that were submitted. My favorite of this group is “Jambalaya on the Bayou.”

Volcano Monitoring Can Be A Risky Business: How Scientists Work Safely - Common PPE used in the field by HVO staff include respirators to filter volcanic gases, gas badges to monitor sulfur dioxide (SO2) concentrations, along with helmets and eye protection.  When molten lava sampling, crews will carry a face shield, fire-resistant clothing, and gloves to protect the wearer from radiating heat.

Best of 2023: Top 42 Photographs From Around the World – I have two favorites in this group of photos: the bald eagles and the dancing mantises!

African Penguins Tell Each Other Apart by Their Polka Dot Patterns – Evidently the chest plumage is unique to each bird….and the birds recognize the dots of their partners!

Photographer Chronicles the Enchanting Life of a Wild Red Fox for 8 Months – A Hungarian photographer’s project at his cottage in the forest after he noticed a fox running under the window one night.

Springfield Art Museum – October 2023

/

One of my favorite places to enjoy with family that visits me is the Springfield (Missouri) Art Museum. This time it was the backup plan; we had originally planned a visit to the botanical garden, but the day was cold and wet.

The museum was not busy, but we weren’t the only people there. We wandered through the Tradition Interrupted exhibit (August 19-November 12). I enjoyed the pieces….recognizing many of the traditions and enjoying the descriptions about the way they were interrupted. Trying to capture the pieces photographically is always part of a museum visit for me; I keep a small camera that fits easily in my purse rather than lugging my bridge camera; it provided optical zoom giving me more options than my phone does. My favorite piece in this gallery is one called Teardrop (middle image below)…a metal piece that imitates embroidery or lacework. The lighting is part of the work and I was only able to capture the shadows immediately behind it; there were also shadows on the ceiling and floor!

The museum is also hosting a series of exhibits in collaboration with Missouri State University. The one showing now is titled Blue on White (July 22 – December 3) – featuring Chinese ware (with connections to Persia)…appropriated through imitation and export to Japan, Europe, and the Americas. Curated by MSU students.

The Creating an American Identity exhibit is a semi-permanent rotating exhibition from the museum’s collection of over 10,000 objects. The middle one below is an early Jackson Pollock – created in the 1930s before he became famous for ‘drip’ paintings!

There is a copper sculpture that I’ve seen every time I have visited the museum. It is difficult to photograph because the background is always so cluttered. This view is about as good as it gets!

The Survey of Ceramic Art is also a semi-permanent exhibit. Even if many of the pieces are ones I’ve seen before, I like ceramics so much that it is probably my favorite exhibit/gallery in the museum. This visit, I thought about how lighting of objects makes a big difference….but often reflections from glass cases is problematic; it’s more apparent in photographs but it distracts even when simply viewing the pieces.

I waited until the end to photograph the Chihuly chandelier in the foyer of the museum. It’s titled Autumn Persians and Feather Chandelier. I zoomed in to eliminate a spotlight; the lighting of the piece is required…but it can also be a distraction.

Most of the plantings around the museum were fading fast…and it was too wet to walk around for botanical photography.

The museum was a great way to spend a wet fall afternoon!

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.

Intact Roman-Era Sarcophagus Discovered in France – From the 2nd century AD, sealed with iron clasps, weighs about 1,700 pounds. It hasn’t been opened yet, but x-rays and an endoscope camera have revealed the contents.

Selective removal of aging cells opens new possibilities for treating age-related diseases - Aging cells, known as senescent cells, contribute to various inflammatory conditions and age-related ailments as humans age. The researchers created technology that specifically targets organelles within aging cells to initiate the cell’s self-destruction. There is still a lot of work to be done (and preclinical and clinical trials).

Cloud Rings Around a Volcano Takes Top Prize in ‘Weather Photographer of the Year’ Contest – Capturing dramatic weather moments…

Brainless Jellyfish Are Capable of Learning - Experiments that provide evidence that box jellyfish are capable of associative learning, or the process of linking two unrelated stimuli together.

How maps can protect children from extreme heat - Heat is becoming increasingly dangerous and it's a threat that is not going away. Community heat maps may not solve the long-term problem, but they are a step in the right direction, by providing awareness and empowering vulnerable children and their families.

Stunning 16th-Century Turkish Bath Reopens in Istanbul - Called the Çinili Hamam, the revitalized site won’t offer traditional bathing until 2024. In the meantime, however, it will feature private gardens and contemporary art in the newly discovered Byzantine cisterns that originally fed the baths. Nearby, a new accompanying museum will display objects associated with traditional bathing rituals—including towels, bowls and ornately decorated wooden shoes—and explain the baths’ original water and heating systems. It will also showcase artifacts from the Byzantine, Roman and Ottoman periods uncovered during the restoration.

The Resiliency of Urban Wildlife - Four distinct sets of traits that help urban wildlife adapt and survive in environments that seem hostile to animals: diet, body size, mobility, and reproductive strategy. Important to know since if you look at the traits animals are adopting to survive in urban environments, you can see how cities could be modified to become more habitable to a wider variety of species.

See the Trove of Ancient Treasures, including a Shrine to Aphrodite, Just Discovered in an Underwater City Off the Coast of Egypt - Thonis-Heracleion was Egypt’s biggest port for centuries, before being surpassed by Alexandria. The city was eventually lost thanks to a combination of rising sea levels, earthquakes, and tsunamis, disappearing beneath the waves along with a large section of the Nile delta. It was largely forgotten for centuries, until 21st-century archaeologists began investigating.

New Patch Inspired by Octopus Suckers Could Deliver Drugs Without Needles - A tiny, drug-filled cup that sticks to the inside of the cheek like an octopus sucker. The device is easily accessible, can be removed at any time and prevents saliva from dissolving the drug, which gets absorbed through the lining of the inner cheek.

Buried ancient Roman glass formed substance with modern applications - Photonic crystals were created by corrosion and crystallization over centuries. If we could significantly accelerate the process in the laboratory, we might find a way to grow optical materials (i.e. materials for communications, lasers, solar cells) rather than manufacture them.

Missouri Botanical Garden – Chihuly

/

I enjoyed the Chihuly glass exhibition at the Missouri Botanical Garden the second time as much as I did the first time…. photographing the pieces during the day and then in the evening. There were some differences between the two visits.

My husband was enjoying photographing them too, so the pacing of our visit was slower around the glass than it had been with my daughter (who did not bring a camera other than her phone).

It rained for about 30 minutes during the Chihuly Night event! We spent most of it in the visitor center then made a quick round of the pieces we wanted to see when it stopped – with lightning in the distance. It was not a leisurely stroll…rather an exhaustive power walk between the glass installations.

The lightning for the Chihuly night was not as robust. It seemed that the lights were configured at the beginning of the installation and then not maintained for the duration of the exhibition (i.e. some were poorly illuminated during the second visit).

I attempted to capture the structure within the glass more than I did the first time.

The Fiori boat has a lot of interesting shapes that I hadn’t noticed during the first visit!

Last time, I photographed the yellow glass on the rose garden arches…but didn’t realize that they were owned by the garden and not in the exhibit brochure. I remembered to look for the name of the piece in this second visit: Trellisses.

I’m glad we made the effort to go again…in September when the Chihuly Nights were still being offered. The exhibition will end in mid-October. Next time I visit the garden, I want to tour the Tower Grove House!

Four key questions on the new wave of anti-obesity drugs – Several of the drugs were originally developed to treat type 2 diabetes but now are popular weight loss drugs.

Sweet smell of success: Simple fragrance method produces major memory boost – A study done by the University of California, Irvine on older adults…participants reaped a 226% increase in cognitive capacity compared to the control group. A product based on their study and designed for people to use at home is expected to come onto the market this fall.

How the US is fighting back against deadly floods – Identifying flood plains…not building back in them after a flood.

Old-Growth Trees, Some Dating To 17th Century, Protected at New River Gorge – The Burnwood Loop – where I want to hike first in the New River Gorge National Park and Preserve!

Does Cooking with Gas Stoves Hurt Indoor Air Quality? – Yes…but how much is the better question. 12.7% of current childhood asthma in the United States is attributable to gas stove use.

A quick look inside a human being – Magnetic Particle Imaging (MPI)…using a portable scanner to visualize dynamic processes in the human body such a blood flow.

Why it's so important to figure out when a vital Atlantic Ocean current might collapse - Humans are changing the fundamental processes of the Earth faster than we can understand them. The collapse of the current would have effects around the planet: temperatures in Europe would fall, heat in the tropics would rise, rainfall would decrease across the Sahel in Africa, the summer monsoon would weaken across Asia, and sea levels would rise even faster in the eastern US.

Short bursts of daily activity linked to reduced cancer risk - A total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers (i.e. cancers associated with physical activity such as liver, lung, kidney, gastric cardia (a type of stomach cancer), endometrial, myeloid leukemia, myeloma, colorectal, head and neck, bladder, breast and esophageal adenocarcinoma (cancer of the esophagus) by up to 32 percent.

Chihuly (glass) in the Missouri Botanical Garden

/

My daughter and I made big plans to see the Chihuly pieces in the Missouri Botanical Garden in late June. We made reservations a week in advance to see the gardens (and glass) at night on our first evening in St. Louis…and then planned a daytime walkabout on our last morning. We got to the gardens a little after 6 PM to have dinner in the garden restaurant (Sassafras) and the enjoyed the gardens until about 9:30 PM…from dust to dark. For our morning visit we arrived shortly after the gardens opened. I took pictures frequently…managed to photograph all the Chihuly works listed in the brochure plus 3 more. It was well worth the effort to see the glass several times…in varying light. Enjoy the images….and plan a visit to the gardens if you can! (Note: To see larger images click on any of the images in this post)

Mound City Glass (historical catalog)

/

The 1889 catalog of the Mound City Glass Company in St. Louis, Missouri showcases ornamental glass offerings. They did beveling, sand blasting and embossing….as well as having a stock of plate glass.

Catalogue from the Mound City Glass Co.

 Old catalogs reflect the availability and popularity of wares…become a historical record of consumerism of the period. In the late 1800s, the country had a wide range of housing from sod structures to the first skyscrapers. People needed windows to provide light inside those structures so improvements in plate glass production during the 1800s was welcomed. The type of glass produced by the Mound City Glass company must have been popular for anyone with enough money to purchase it…letting light in along with providing a decorative element.

There isn’t much information about the company other than the catalog. The address on the catalog was in downtown St. Louis…maybe the offices/showroom rather than where the glass work was done.  I assume that the ‘mound city’ in the name came from Cahokia mounds which are on the eastern side of the Mississippi across from St. Louis. There are places in Kansas, Missouri, Illinois, and South Dakota named Mound City; the one in Missouri is on the other side of the state - north of Kansas City close to the Missouri River; the one in Illinois is in far southern Illinois on the Ohio River which is their border with Kentucky; it doesn’t seem likely that either one would have been the location of the original manufacturing facility.
