Gleanings of the Week Ending March 4, 2023

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

Can clothes ever be fully recycled? – Evidently a lot of progress has been made in the past few years – translating processes from small to large scale production. But recycling is not the only thing that needs to change about the fashion industry. ‘Fast fashion’ is cannot the future!

A simple thing you can do to benefit backyard birds and bees – Wait until it is 50 degrees to do spring cleaning around your yard. Those leaves and dead stalks harbor insects….and birds need insects, particularly when they are raising their young! I have a big tuft of ornamental grass which I am waiting to cut. Last summer it was full of insects and I except some eggs/larvae are there now.

An incredible journey – Chinook making their way up the Klamath River in the spring and fall. (infographic)

Nearly 30 dangerous feedback loops could permanently shift the Earth’s climate - A change….triggering more change…a cycle. Our planet is full of complex connections that are often not well understood.

As Millions of Solar Panels Age Out, Recyclers Look to Cash In – Hopefully solar panels, and a lot of other end-of- life products, can become part of the ‘circular economy’ rather than going to landfills.

See Thousands of Sandhill Cranes Gather in Nebraska – Maybe next year we’ll plan to go to Nebraska to see the crane migration!

The beautiful flowers that bees can’t use – Nectar deficient hybrids (like double petal petunias) or non-native plants often don’t provide food for pollinators…even though people find bigger, brighter flowers appealing. The article also provides a link to a free book: Pollinator-Friendly Parks which might be useful for homeowners who want to support pollinators.

Anti-dust tech paves way for self-cleaning surfaces – Wouldn’t this be nice…my computer screens seem to attract dust!

'The Great Displacement' looks at communities forever altered by climate change – A book review that documents people surviving a hurricane in the Florida Keys or a big fire in California (and other climate change related disasters) and making decisions in the aftermath. A quote from the author, Jack Bittle: "In the United States alone, at least twenty million people may move as a result of climate change, more than twice as many as moved during the entire span of the Great Migration."

A Long Low Tide Dries Up Venice’s Smaller Canals – Wow…we usually think of Venice being more prone to flooding.

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 ancient diseases that plagued dinosaurs – Interdisciplinary teams are re-looking at dinosaur bones and comparing anomalies to diseases visible in modern bones….finding examples of dinosaurs with malignant bone cancer, septic arthritis, and airsacculitis. And it seems that there is a lot more to discover with the technologies now available to look at the fossils more closely and collaborating with vets (particularly vets that work with birds and reptiles).

A worthless life and the worthy death: euthanasia through the ages – The post is written from an Australian perspective and about Caitlin Mahar’s book: The Good Death Through Time. The topic is a thought provoking one….made more interesting with an overlay of history.  I wondered how much the growth of medical interventions has changed the way we envision ‘worthy death’ or is the phrase ‘death with dignity’ a better description now.

Residential solar advantages – 5 top benefits – This is something my husband and I plan to do…solar-plus-storage is our 1st choice. Residential solar also has advantages beyond the home itself: it can power your transportation home too!

Fructose could drive Alzheimer’s disease – More research is needed…but it is interesting that the fructose consumption has gone up in the US (in 1977-1978 it was 37 g/day….in a 2008 study, it was 54.7 g/day). Maybe reducing the risk for Alzheimer’s is another reason to eliminate ultra-processed foods that typically contain a lot of fructose from our diet.

High-paying jobs that don't need a college degree? Thousands of them are sitting empty – Making a career in the trades….and there is a lot of work available.

Why methane surged in 2020 – Interesting findings and how they were developed. The two main reasons: 1) heightened emissions from wetlands because of unusually high temperatures and rainfall and 2) decline in NOx due to COVID-19 lockdowns which broke the chemical reaction in the atmosphere that produces hydroxyl (OH) that serves to remove methane from the atmosphere.

Why aren’t energy flows diagrams used more to inform decarbonization? – Yes! These are easier to understand than a lot of other graphics. The ‘heating the UK with heat pumps or green hydrogen’ diagram caused a ‘learned something new’ moment for me!

Will we ever be able to predict earthquakes? – The answer might be ‘no’ – but there are still a lot of people trying. We can’t rely on predicting them to reduce the destruction in infrastructure and lives. Enforced building codes would reduce destruction and save lives since we already know the areas of high risk for earthquakes. It will be interesting to see an analysis of what the damage from the recent Turkey/Syria earthquake would have been if building codes would have been enforced (the ones that Turkey evidently instituted after the previous earthquake…and also if the ‘best in world’ standards has been enforced).

15th-Century Spices Identified in Royal Shipwreck – Analysis of plants from a 1495 shipwreck in the Baltic Sea off the coast of Sweden: nutmeg, cloves, mustard, dill, saffron, ginger, peppercorns, almonds, blackberries, raspberries, grapes and flax. The findings provide insight on cuisine and trade of the era.

Did you know pronghorns shed their horns? – No…but it a good piece of trivia. I remember seeing pronghorns in New Mexico – racing our vehicle during a guided tour of Sevilleta National Wildlife Refuge.

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

Farmers Find Wild African Cat Wandering Around Missouri – A serval found when a farming family set a live trap to capture the culprit leaving bones and feathers between their stacks of hay bales! The Turpentine Creek Wildlife Refuge came to the rescue. This is all close to where I live and I was saddened that evidently the new Big Cat Public Safety Act does not include the smaller non-native wild cats…and that someone was cruel enough to release this cat of the African savanna into the wild in Missouri.

Caribou have been using the same Arctic calving grounds for 3,000 years – Analysis of antlers found on the tundra….discovering some of them are 3,000 years old! But the Arctic is warming faster than other parts of the globe. The elders of the village south of the calving grounds comment that they have noticed a lot more trees, less barren tundra. What will happen to the barren ground caribou as this habitat gets converted to forest?

Why fabric fraud is easy to hide – The fashion supply chain is fragmented and very dense….most apparel companies do not track their own supply chain (or don’t go past their immediate suppliers). Organic cotton is one of the prime examples of how end products labelled as organic cotton…might not be. It is hard to determine where the fraud is inserted in the process; the result is that the consumer is paying a premium price…not getting what they are paying for. And to improve the system will require big changes in the fabric/apparel business.

A Field Guide to Unexpected, Out-of-Place Wildlife – Sometimes animals have ranges that are changing or are a lot larger than we anticipate…sometimes birds are in very different places that their usual range!

Dirty Laundry: How much microfiber do we emit with our laundry – A study done in the UK…but probably relevant to the US as well. Microfibers from laundry in the UK weigh 6,850 to 17,847 tons per year. Yes…that’s a lot and pollutes water…however, it is a dwarfed by the 365,000 tons of clothing going into UK landfills per year.

Antibiotic use in farming set to soar despite drug-resistance fears – The increase in bacterial infections that cannot be treated with antibiotics (because of bacteria developing resistance to antibiotics) has been growing in recent years. Overuse of antibiotivs in agriculture is thought to be a major driver of the problem. Governments around the world have attempted to curb the use of antibiotics to promote growth but the use is still expected to grow by 8% between 2020 and 2030. The article includes a chart of agricultural antibiotics by country in 2020…and a projection for 2030.

The Lifelike Glass Models of Leopold and Rudolf Blaschka – Thousands of realistic models of plants and sea creatures made by a father and son from the 1860s until 1938.

8 everyday foods you might not realize are ultra-processed – and how to spot them – I am cutting back on ultra-processed foods this year. Some of the 8 listed in this article are easy: I don’t eat breakfast cereals, I only eat protein bars as ‘emergency rations’ (i.e. not frequently) and avoid yogurt, meal bases and sauces, processed meats, and margarine. I’m still looking for a soy milk that has fewer ingredients; will give up on soy milk soon if I don’t find one. And I try to buy bakery bread.

Did Philip II bring invasive fish to Spain? – Evidently his efforts to acquire fish and crayfish from afar spanned at least 25 years!

Study reveals that much still not known about cognitive decline - Data came from 7,068 participants in the 1996-2016 Health and Retirement Study. Participants were born between 1931 and 1941. Researchers measured their cognitive functioning at age 54 and how it declined until they were 85. At age 54, socioeconomic status, education and race -- explained only 38% of the variation in functioning. Those same factors explained only 5.6% of the variation in how quickly cognitive functioning declined in people between age 54 and 85. So much we don’t know about cognitive decline although it is pervasive in older adults, even those without dementia.

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

Why the world feels so unstable right now – Intermittent instability of nonlinear systems of nature and global society –weather and climate, the economy, a pandemic, a war. We attempt to model nonlinear systems to predict these intermittent instabilities…but it is hard. Right now there seem to be significant nonlinear systems interacting: weather/climate + diseases (COVID-19 and bird flu (US)) + inflation + Russia’s invasion of Ukraine.

Completing The Electrical Circuit at Kilauea in Hawai'i Volcanoes National Park – The technique to get a detailed ‘CAT scan’ of the volcano…..mapping locations of subsurface magma in 3D.

Ex-cell-ent Clouds off Chile’s Coast – Open and closed-cell marine stratocumulus clouds photographed by Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. Learning more about these clouds….contributing to better weather prediction and improving the accuracy of climate models.

The Surprising Substances Ancient Egyptians Used to Mummify the Dead – Evidently some of the substances the embalmers were using came from Southeast Asia. Perhaps embalming instigated early global trade.

Algae robots transport antibiotics to infected tissues (infographic) – Researchers inserted the modified algae into mouse windpipes…they spread into the lung tissue and killed pathogenic bacteria!

Hundreds of Frank Lloyd Wright’s Designs were never built. Here’s what they might have looked like. – Computer generated models from David Romero.

5 expert tips to protect yourself from online misinformation – We all need tools to help us distinguish information from misinformation.

Montessori: The world’s most influential school? – I sought out a Montessori pre-K and K for my daughter about 30 years ago…and it fit her needs. I have no way of analyzing how closely the school adhered to classical Montessori ideals.

An action plan to prevent Alzheimer’s disease – Defining what 2nd generation memory clinics should include.

Gallup: Fewer than half of Americans believe US healthcare is good enough – Not surprising really – it’s expensive and we are all getting more skeptical that the system is as effective as it should be for what it costs. Evidently the people in my age group (over 55) were generally more satisfied with their health care than other age groups; people old enough to qualify for Medicare may not be as anxious about costs but I was surprised that I am in the minority in thinking US healthcare is ‘subpar’ rather than ‘excellent’ or ‘good’ based on the effectiveness issue and the structure of the system overall.

Spring Yard Dreaming

Moving to a new area of the country….a new house…I am full of dreams for the yard.

I’ve already bought way too many seeds for the existing flowerbeds. Most of the beds contain landscaping cloth covered by river rock. Maybe I could plant mini-pumpkins in those beds by poking a hole in the fabric. I’d like to grow enough plants to have a good harvest in the fall. I’ve already identified some beds in the back of the house that will be changed dramatically. And there are areas between trees that I will turn into flower beds because I don’t want to mow there. One plant I want to grow…and harvest…is stevia; my CSA in Maryland had hardy plants that withstood harvesting of their leaves/small branches all during the growing season; putting a few leaves to steep with tea gives just a hint of sweetness that I enjoy; I will order organic seeds.

I have chives seeds gleaned from my parents’ Carrollton yard that I will plant to grow as ‘edges’ of flower beds. Since I purchased seeds as well (that have pink flowers) I will probably mix those seeds with the ones I gleaned to add splashes of color/texture variety.

My larger plan it to plant some native bushes in the back yard to reduce the amount of yard that is mowed and have some deeper rooted plants on the slopes at the side of the house. I need to go to a nursery to hone my list of natives that are hardy in this area. I’ll ask about some of my favorites: oak leaf hydrangea, beautyberry, and ninebark. I’d like to plant something that would provide winter food for birds; maybe the nursery will have some recommendations. I need to check the guidelines from our Home Owner Association to see if I need to get permission; if I do, hopefully it will be an easy process.

February is the ‘yard dreaming’ month….I’ll need to act soon to make it happen…but maybe it won’t all get done in 2023!

A Patient Perspective of Medical Care in the US

Part of the aftermath of making a long distance move is establishing new doctors. I’ve completed the process at this point – 8 months after the move. It’s been a learning experience. I started out with the intention to find a primary care physician and specialists in the same system so that I would only have one portal for all my medical information – unlike my legacy situation that involved at least 4 different portals. The portal for my new doctors is well organized and has become the primary way I get results and send questions/messages to my doctors. In general, the lab work is done very quickly and posted on the portal; I see it about the same time that the doctor sees it. The system of doctors – specialists – labs – hospital also includes several urgent care facilities that I appreciate; their availability can help avoid a busy ER; I’ve already used an Urgent Care facility prior to my first appointment with my new primary care doctor when I got a very painful bite that looked infected. On the downside -

• Vision and dental care are not general part of ‘medical care’ from an insurance perspective or systems with MDs; vision and dental are still separate. The initial dental practice I selected wanted to do very different (and expensive) kinds of cleaning for my teeth and I’ve opted to go to a new one that is more like the dental practices I’ve used in the past. It’s hard to know how to evaluate dental recommendations since they are outside of the primary medical system. I like the vision care practice I chose but may have similar misgivings as I get closer to needing cataract surgery.

• The various specialist doctors and non-blood labs/radiology are in separate buildings; they are relatively close together, but I am careful to record the building address  in my appointment calendar; it’s a high traffic area and it could be challenging to get to the appointment on time if I went to the wrong building first.

Thinking about the big picture of medical care in the US - It is not achieving ‘best in world’ results based on healthy lifespan stats. Why is that?

• Insurance is expensive and confusing. I’ve had health insurance since the late 1970s and the trend has been increasing cost and complexity over the duration. Checking that doctors are in-network and drugs are ones that are on the formulary is a required skill to get insurance to cover costs….and even then, sometimes surprise charges occur. What happens when your doctor prescribes a drug that is not on the insurance company’s formulary? I am very aware that I have been fortunate to always be insured….understand that the cost of good medical insurance is prohibitive to many and that often means not getting medical care until there is a health crisis…and going to an emergency room.

• Cultural reluctance/aversion to embrace public health measures. Over the past decade, there has been increased resistance to public health measures (for example, not getting vaccinations for children, older adults declining vaccines, flying when sick (coughing, sneezing),  and aggressively against mask wearing at any time) and demands on health professionals for treatment that is not appropriate for their condition (for example, demanding an antibiotic for a viral infection or are an ineffective drug for COVID or a drug advertised on television that is for a condition the patient does not have). I am mentioning the demands for inappropriate treatment under public health because it impacts the costs for medical care overall, increases resistance of microbes to antibiotics making them less effective when they are needed, and makes the workplace for doctors/nurses more stressful (and some decide to leave the profession resulting in shortages of skilled personnel).

• Dominate lifestyle. We live in a world of fast food and ultra-processed foods…people are more sedentary because of their jobs or the type of entertainment they choose. It is harder to “eat healthy” now that when I was growing up and as a young adult. Many people in the country are obese and/or in poor physical condition. However – there are a lot healthier foods available now if we educate ourselves. For example – kale was not something I ate as child, now it is my ‘super green’; other foods that I’ve only know in the past 20 or so years include: pomegranates, edamame, beet greens, red cabbage, butternut squash, ground turkey. There are also a lot of ways to measure physical activity…and some have leveraged those metrics to become more physically fit. Still – healthy lifestyles are not as prevalent now. The bump in life expectancy that was achieved after many people managed to stop (or not start) smoking is being eroded.

• Aggressive intervention with drugs. The medical system tends to treat with drugs rather than recommending lifestyle changes. Part of this skew is the way doctors are trained (often nutrition is not included in their education) and part is probably based on their experience that most patients will not follow through and make a change. If a drug can change the measure the doctor is seeing (like blood pressure or cholesterol levels), then the doctor tends to immediately medicate. Any unwanted side effects from the drugs are resolved through changing to a different drug or adding a drug to reduce the side effect or telling the patient that the benefit of the drug is greater than the impact of the side effect. But – if people can change their lifestyle, they are probably addressing the root cause of the problem rather than artificially doing something that changes the measure but leaves what is causing the problem the same. Long term maybe we’ll know if the drugs really do very much for increasing healthy lifespan.

• Specialists with blinders to anything outside their specialty. The notion that a primary care physician can integrate care is overly optimistic.

  • Many times, the specialists are proceeding with their focus; if treatment is meeting the measures they want, side effects or over medication are not a priority for them.  For example – an endocrinologist adjusting medication to get the levels of hormones to a precise level is often unconcerned or dismissive of a patient reporting heart palpitations, hot flashes, and eyebrows falling out.

  • Emergency room doctors are focused on resolving the primary cause of the emergency visit and sending the patient home as soon as possible; this leads to quick fixes that often do not prevent the same issue occurring repeatedly. A good example is cellulitis in older patients; the ER gives them antibiotics and they go home…often returning with cellulitis again in a month or so. If the ER is not overwhelmed and there is an alert attending in the ER or in the hospital, more proactive measures can be taken…perhaps re-evaluating the dosage levels and complexity of existing medications, adding a prophylactic antibiotic, etc. that can prevent rapidly recurring ER visits for cellulitis.

• Lack of trust. Patients believe doctors may have alternative incentives than patient health when recommending treatment/drugs and doctors believing patients may not be doing as they say and/or taking meds as prescribed. Not sure how this can be bridged other than encouraging more transparency on both sides.

The bottom line – I want to believe that I am proactively maintaining my health and being a knowledgeable patient that asks relevant questions to understand my doctors’ logic….thus making the best of the medical care available…but there are certainly times that I have some doubts. So far, I have been able to resolve those doubts and am satisfied that I am on a healthy path. However - I am increasingly concerned about individuals with fewer financial resources, less healthy or not as knowledgeable. The trend is toward more challenges within the US healthcare system!

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

Milk packaging influences its flavor – Light blocking containers are best….and plastic/glass is better than paperboard. So why aren’t paperboard cartons being phased out (they are also harder to recycle than plastic milk cartons).

Clean Energy Saw as Much Investment as Fossil Fuels for the First Time in 2022 – Good! And hopefully this will continue to be the case…and we don’t allow any fossil fuels to be counted as ‘clean.’

What Secrets Lie Beneath This 17th-Century French Aristocrat’s Smile? – Decaying teeth and an ivory prosthesis (in front) held in place with gold wire….and a woman kept her smile and place in society.

A curious Colorado bear strikes a pose for 400 selfies on a wildlife camera – A bear that noticed the camera!

Leprosy: the ancient disease scientists can’t solve – There is treatment…but diagnosis is complicated and there is no cure. And we still don’t know how it is transmitted.

Researchers find rare 17-pound meteorite in Antarctic ice – A team spent a week and half in the Antarctic summer (14 degrees Fahrenheit…so still very cold) sleeping in tents and riding snowmobiles to search for meteorites. They found small ones….and a big one!

New mosquito repellents that work better than DEET – Maybe the next generation mosquito repellent?

In 2021, 20% of electricity in the US was generated from renewable sources – And wind surpassed hydroelectric in 2019 as the predominant renewable source. Hopefully, the percentage of electricity from renewables will go up quickly in the coming years.

Three grizzly bears tested positive for avian flu in Montana - The animals were euthanized in the fall; suspected to have rabies, they tested negative. But they were positive for avian flu. The bears were ‘in poor condition and exhibited disorientation and partial blindness, among other neurological issues.’ So – the current outbreak of avian flu that has impacted wild and domestic birds (more the 52 million have been killed or culled to contain the virus) is impacting more than birds.

Drone video of moose shedding its antlers – Wow – it happened so quickly; the video is only 16 seconds! The moose just shakes its body, and the antlers fall off. It seems to want to leave the scene quickly once they are off too.

What links litmus paper and lichens? – How did I not know that litmus dye was made from lichens? I remember using red cabbage to tint paper for an elementary school science project with my daughter. We tested everything in the house…discovered that even the fumes from toilet bowl cleaner turned the strips we made bright pink!

How donkeys changed the course of human history – The beast of burden. During Roman times the subspecies used was larger than modern donkeys…specifically bred for the expanding empire.

Jungle realm of the Snake Queens – A 5-part article about 2 Mayan queens: Lady K’abel and Lady Six Sky.

Marriage in Minoan Crete – A surprise – it was very common to marry one’s first cousin!

Kenya’s Rift Valley lakes are rising, putting thousands at risk – A study reveals that there have been increases in rainfall since 2010…an increase of only 0.4-2% of mean annual rainfall leads to the observed rising lakes/flooding.

EPA requirement keeps electric buses out of low-income schools – Low-income school districts often don’t own their school buses; they rely on contractors or subsidized lease deals. So --- they can’t meet the requirement to scrap the old diesel buses.

Ten-minute scan enables detection and cure of the commonest cause of high blood pressure – The hormone aldosterone causes 1 in 15 cases of high blood pressure. This new technology/treatment is a big improvement for the way those cases can be treated.

Dead Humpback Whale Washes Ashore at Assateague Island – This is the second one recently. I am familiar with the place this time…Assateague Island was a place my husband and enjoyed for birding when we lived in Maryland.

China’s population declines for the first time in six decades – Changing demographics in China.

Bees exposed to common weedkiller via wildflower nectar – Evidently the flowers can be contaminated even if they are not sprayed directly!

How do snowflakes form? Is each snowflake really unique? Why is some snow light and fluffy or heavy? The amazing science of snow – A good topic to explore in the winter! The article includes a video of snow and ice crystal growth.

Falling birth rate in US not due to less desire to have children – People are not having as many children as they say they want, especially at earlier ages. There is some evidence that people reduce the number of children they intend to have as they get older. They may realize how hard it is to have and raise kids in the US…and decide to only have one child rather than two. They may have more challenges conceiving as they get older too. Larger economic and social forces are also impacting birth rates.

Meditation and mindfulness offer an abundance of health benefits and may be as effective as medication for treating certain conditions – An overview of the strengths/weaknesses of studies about mediation/mindfulness…a good introduction.

Drone Photography Celebrates the Beauty of Historic High-Rise Buildings in the U.S. – Wonderful views of the highest parts of tall buildings.

9 in 10 drivers in the US would save money on fuel by going electric – Good! Hopefully the cost of the electric cars will come down a bit…and we’ll have more models to choose from…and the places to charge them during road trips will be convenient.

Why obesity is more dangerous for men – Evidently men have a lot more inflammation associated processes and don’t grow as many new blood vessels in their fatty tissue.

See the Lavish Pompeii Home Owned by Two Men Freed from Slavery – Reopened after 20 years of restoration work. It was originally excavated in 1894-1895.

Broccoli looks more like cauliflower in a warmer world – Looking at the chemistry behind the changed growth of broccoli at higher temperatures…avoiding the change in the lab…but will it enable us to still produce broccoli that looks like broccoli as the planet warms?

Another step toward an insulin tablet - A lot of diabetics would appreciate ‘no more injections’!

Why Electrifying Everything Is a Critical Pathway to Decarbonize The World & Our Lives – I like these articles that get specific about the options that individuals/families can take. It gives me more hope for my future and the future of the planet to take the actions I can to 1) decarbonize the electricity used by my home, 2) move toward an all-electric home and transportation, 3) improve efficiency/reduce waste, and 4) sequester carbon. Focusing on the ‘all electric’ concept this week. I have natural gas powered heating and hot water heater…will probably replace the heating/cooling first. The gas fireplaces are turned off already – removing them is not a high priority.

2023 Diet (Strategy)

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

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

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

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

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

The theme for my 2023 diet is:

‘Good for me…and for the planet.’

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Ten Remarkable New Plants Discovered in 2022 – And one of them is the largest waterlily on Earth…from Bolivia.

Shrinking Pollinator Populations Could Be Killing 427,000 People Per Year – The world is losing 3-5% of its fruit, vegetable, and nut production because of shrinking pollinator populations and lower pollinator diversity. That translates into less healthy food available…and associated health conditions like diabetes and heart disease. In Honduras, Nepal and Nigeria, the pollination deficits are responsible for a reduction of 3-19% in crop yields. This highlights the importance of making changes to support pollinator populations such as limiting pesticide use, maintaining existing natural habitats, and restoring others, and planting more flowers and diverse plants.

Overlooked Gems of The National Park System – In the cold of winter…time to plan some trips to parks for the year…including a few of the overlooked gems highlighted in this article.

Snow Day in Delmarva – Reminder of the area where we enjoyed a lot of day trips while we were living in Maryland….

H5N1 Bird Flu Detections across the United States (Wild Birds) – A map of US counties where bird flu has been detected in wild birds as reported by the US Department of Agriculture.  It would be great if data could come from the National Wildlife Refuges (reporting through the US Department of the Interior) since they often have concentrations of wildlife and staff that would be monitoring the flocks. I know that there were instances of bird flu – primarily in snow geese - that the Bosque del Apache NWR staff were reacting to when we were there the November before COVID-19 curtailed our travel.

Electric car sales drive toward cleaner air, longer lives – Another reason my next car will be an electric rather than a plug-in-hybrid that I have now. However – this should probably be seen as an offset to the negative impacts on public health that climate change will bring; the air could be cleaner, but it will also be warmer and more turbulent. I am becoming less certain that my lifespan will last into my 90s like it has for my parents.

Living the lava life on Mauna Loa – A satellite image from NASA’s Landsat 9. It shows how close one of the flows came to Hawaii Space Exploration Analog and Simulation (HI-SEAS) project habitat. Fortunately, the most recent mission there concluded in May 2022.

The Dead Sea is dying – The lowest exposed place on Earth…water level dropping 4 feet per year…salt formations and sinkholes.

Beyond cola: the strange flavors of soft drinks – Carbonated drinks were invented by Johann Jacob Schweppe in 1783. They were sold in glass bottles and that were recirculated. Regional delicacies. Everything changed with the advent of plastic bottles in the 1970s. Moxie, state beverage of Maine, continued independently for a long time – bought by Coca-Cola in 2018. Soft drinks had a heyday in the years of Prohibition. Follow the link for the whole article, more soft drink history.

Construction of the world’s largest radio telescope begins – Square Kilometer Array (SKA) – one in Australia and one in South Africa. Construction will be completed by the end of the decade, but observations will begin in 2024.

The 120-year search for the purpose of T. Rex’s arms – A little history of T. Rex finds…and the various ideas about why the animal had such puny arms.

A new weapon against antibiotic-resistant bacteria – Work to find a new treatment for Klebsiella pneumoniae infections that are resistant to common antibiotics with some strains fatal for 40-50% of infected people. A new strategy: weakening bacteria with an existing drug previously used to treat herpes that alters its surface layer to make it easier for the immune system to kill the bacteria. The idea works in the research model…effectiveness in human beings yet to be confirmed.

The science of why hawks are one of nature’s deadliest hunters – Birds and bats….The birds steer toward a fixed point in the swarm instead of singling out a bat. It’s a good strategy against a gathering of prey!

Battle Over Bears Ears Continues in Utah – I am looking forward to visiting Bears Ears and Grand Staircase-Escalante National Monuments and hope that their boundaries stay the way the tribes that have used the area for a very long time want. At some point Utah and the counties that are opposing the size will recognize the values of the tribes and country that want to preserve historical, paleontological, and geologic aspects of these places….and that the state benefits significantly from people visiting. The tourism $ may become more dependable and long term than other uses of the land.

Pyramid and Hundreds of New Kingdom Coffins Found in Egypt - An Old Kingdom pyramid, 300 New Kingdom coffins with well-preserved mummies with names of the deceased, and nearby a pyramid to Queen Neith…a previously unknown Queen.

Long-COVID clinics are wrestling with how to treat their patients – Frustrating situation.

Parks of the 21st century: new ways to reinvent abandoned land – Parks always are signs of hope…the greening of places that might have been eyesores in the past. I wondered how much toxic remediation had to occur for some of the sites they described; its encouraging that we can clean up the messes we’ve made in the past!

Alcohol caused one in eight deaths of working-age US adults – The data used from the analysis was pre-COVID-19 pandemic. Recently, the CDC has released data for 2019 and 2020 and it shows a larger-than-normal 26% spike in the alcohol-induced deathrate. In 2020, alcoholic liver disease and mental/behavioral disorders were the leading underlying causes of alcohol-induced deaths. Sad numbers….lots of people and their families impacted.

Permanent Standard Time Could Save Lives, Explained by A Sleep Expert – I don’t like changing to/from daylight savings time; before reading this article, I didn’t care which one we chose to make permanent. Now I am convinced that we should stick with standard time! There are too many negative health impacts to staying on daylight savings.

How to avoid bad choices – The article is about the research on how to teach children ‘decision-making competence’ – not just a measure of raw brainpower but how well someone is able to appraise situations. There are many approaches but the goal is to get children and adolescents to start thinking about risk and danger in a more analytical way….on the way to adulthood.

Blind spots in the monitoring of plastic waste – The amount of plastic waste in rivers could be up to 90% higher that previously assumed. The current measurements are mainly based on surface observations…but plastic can be suspended or sink! This study tracked 3,000 particles from 30mm to larger objects like plastic cup. Knowing where the plastic is helps guide where clean up would be the most effective.

Greater cloud cover may be narrowing the gap between daily high and low temperatures – Simulating clouds explicitly. Trying to understand why nights are heating up faster than days across the globe.

Spoils of Halloween

My son-in-law always hosts a pumpkin carving party for his research team before Halloween. This year, 10 pumpkins were purchased for the event; it took two carts to get the pumpkins from the store to the car.

My daughter missed getting a group picture of the results…sent pictures of the three they had on their steps for Halloween (with and without the lights inside).

Like last year – the squirrels are enjoying the spoils of Halloween pumpkins! They start with the carved parts…enlarging the eyes and mouth…small bites until there is almost nothing left to go into the compost! They apparently started with the pumpkin on the top step.
