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.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

What a decade of Curiosity has taught us about Mars – Looking for signs of life.

Zion National Park, Utah – A view of the park from the International Space Station. A piece of trivia from the post: Cyanobacterial blooms are a threat to hikers and wildlife – exacerbated by intense summer heat.

Air pollution, including during wildfires, shows ill effects in children -So many questions popped into my mind as I read this article: Does keeping children indoors with modern air conditioning/heating filtered air help? Further air purification required? The children in the study were 9-11 years old; are some of the markers also indicators of stress they may have developed knowing there were wildfires?

Ultra high-speed photography captures hidden human figures in moving water – Eye candy

Heat pumps prove themselves during a harsh Maine Winter – Modern heat pumps do the job even at -21 degrees in Maine!

Neolithic Watermelons may have been valued for their seeds – Snacks! And now most watermelons we buy in stores doen’t have seeds at all!

Nahuku Lava Tube in Hawai’i Volcanoes National Park Closed to study its stability – Also known as Thurston Lava Tube. I walked through it when we were in Hawaii several years ago.

Vitamin K prevents cell death: New function for a long-known molecule – Important for blood clotting….but new research shows it is also a potent antioxidant that ameliorates cellular iron’s role in cell death (ferroptosis). There will probably be a lot of subsequent research following up this finding.

The science of making cheese – Infographic that shows the 4 steps: acidification, coagulation, reducing moisture content, and maturation.

The mysterious inner life of the octopus – Interesting article….or just look at the pictures!

Gleanings of the Week Ending February 12, 2022

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 Dutch embrace floating homes – Maybe other coastal areas around the world should be looking at this kind of development…or mitigation strategy. Otherwise - there is going to be a lot of migration away from coasts that will become more and more prone to flooding in the decades to come.

New Antarctic Penguin Colonies Discovered Further South than Normal – Good news for the Gentoo penguins - there is more space on Antarctica now; previously the areas were too icy for these birds. On the downside – there is less area suitable for penguin species that previously lived there and there might be less food available for them all as warming continues.

Three people with spinal-cord injuries regained control of their leg muscles – There has been a lot of research in this area over the past decade; perhaps we are coming to a point where rapid advances are going to be made.

Why to flickers knock on your house? – Not just why they knock but other interesting behavior…made me consider putting up a flicker box to give them a place to raise young.

Dog feces and urine could be harming nature reserves – A study providing rationale for requiring dogs on leashes and owners removing their dog’s feces in natural areas.

Top 25 birds of the week: February 2022 – My favorite this week is the Great White Pelican. Somehow pictures of birds from the front like this always give them a rather assertive appearance.

US household air conditioning use could exceed electric capacity in next decade due to climate change – Not good. Implementation of mitigation strategies need to ramp up quickly. As an individual homeowner, I am thinking: 1) increase efficiency (heat pump or geothermal, more insulation, solar screens on any window getting full sun sometime during the day, maybe upgrade windows/doors) and 2) solar panels on the roof with storage battery.

Threats from QAnon conspiracists force butterfly sanctuary to close – Sad. My husband and I visited the butterfly sanctuary on a rainy day during the Rio Grande Birding Festival in 2017; it wasn’t a good day for butterflies, but we always thought we’d come back on a warmer/sunnier day during some future visit to the area --- then the border wall and the conspiracists has ended it all.

More spice could help seniors avoid salt – Yes! Lemon pepper (the kind without salt in it) is one of my favorites…and any of the components that come under the heading of ‘Italian seasoning.’ I dry my own orange peel (any time I eat an organic orange…the peel gets processed and dried). It helps to use fresh ingredients too (i.e. avoid no-salt version from cans…they have never tasted good to me no matter how they are prepared).

Star Bright: What are Dark Sky Reserves? – Staunton River  (where we’ve been for ‘star parties’) is a Certified IDA International Dark Sky Park….maybe we’ll visit one of the Reserves post-pandemic. Right now – the closest one to us is the one in Canada (just north of Vermont/Maine).

90 Years

Both of my parents are 90 years old this year. I’ve been thinking about the events of their lives and what has happened in the world during their lifetimes.

Their lives began during the Great Depression. They were both born at home; both families were living in rural Oklahoma and grew most of their own food. They were too young to fully realize the stress around the country…secure with their family and small rural community.

Their school memories are from the 1940s --- the World War II era. Their fathers were too old to go to war so the impact of the war on their families was indirect…primarily the rationing programs. Both went to schools where there was only a small cohort at each grade level. Later in their lives they attended high school reunions occassionally – keeping in touch with that small group that had mostly scattered across the country.

They were in college in the early 1950s – the boom years with the GI Bill funding returning veterans and college being encouraged for those just graduating from high school. My parents were ‘first generation’ to college for their families. They married, left the farm, and had 3 of their 4 children during the decade. My dad’s career stayed related to agriculture initially – at first requiring a lot of traveling and then into management of grain storage.

By the 1960s, they were in Texas living in a small city…children in public schools, living in an air-conditioned house (an important thing in the Texas summer). The big health improvement was the availability of the polio vaccine (we all got the vaccine via sugar cubes at school) and the waning of smallpox around the world even though we were still required to get updated vaccines when we traveled to Mexico.  In the mid-60s my mother returned to college for a degree in education…a career she started in the 1970s. My dad’s parents moved from Oklahoma to the same small city in Texas.

In the early 1970s, they moved to a suburb of a big city. They bought a house that accommodated the whole family, including my dad’s parents. My dad had transitioned completely from an agriculture related career to financial management and planning. My mother was teaching. All 4 of their daughters graduated from high school and went to Texas colleges (the last one just starting at the end of the decade). One daughter got married. My parents’ fathers died during the decade. Somehow everyone managed to stay ahead of inflation and pay mortgages that were high interest compared to today.

The 1980s were a very busy decade with careers of the whole family in high gear. My father was coming adept at digital spreadsheets…my mother was focused on reading for students in upper elementary and middle school. The youngest daughter graduated from college. One daughter (me) moved halfway across the country to the east coast and two others got married. My maternal grandmother died. Toward the end of the decade, the first two grandchildren were born.

In the 1990’s, my parents retired from their careers; they travelled and took care of grandchildren and helped with home maintenance (a total of 5 houses in the family!). Three more grandchildren were born, and the older ones started school.

Similar activities continued in the 2000s changing as the grandchildren got older…the oldest ones starting college.

In the 2010s, travel and engagement with family continued in a similar way for the first part of the decade; by the middle of the decade someone else was doing the driving on road trips and they stopped driving completely by the end of the decade. My paternal grandmother died; she had been living in the same house with my parents since the 1970s. Health challenges began to emerge for both parents…intermittent at first and then slowing them down in the last years of the decade. They both benefited from cataract surgery. Other surgeries and injuries required more recovery time…and sometimes recovery was not complete.

The last road trip was for Thanksgiving in 2019…to be with a grandchild. Not long afterward the COVID-19 pandemic locked down travel and they discovered the comfort of ‘stay at home as much as possible.’ Recently they have transitioned to primary care practice that comes to their home for checkups, blood work and most other health needs. Their children and grandchildren come to them now. If they leave their home, it is a very special event. Four of their five grandchildren have college degrees – one has an MD…another a PhD. There aren’t any great-grandchildren – yet.

So many changes have occurred since they were born. Electricity and indoor plumbing were just beginning to be available on farms when they were born. They bought their first air-conditioned home in the early 1960s. Computers came along in the 1980s.

And now – my sisters and I are thankful they are still with us – still enjoying living independently in their home with support from the family, neighbors, doctors, and house cleaners – getting close to celebrating 70 years of married life.

Ultraprocessed foods now comprise 2/3 of calories in children and teen diets – This article prompted me to look at what ultraprocessed foods I am eating…and making some changes. I am keeping the 1st breakfast that includes 90 calories of dark chocolate…but all the other ultraprocessed foods are going to become occasional or rare in my diet.

Tracking the Restoration of the River of Grass – An interview with Eric Eikenberg, President of the Everglades Foundation. There is a lot of work coming to fruition this decade in restoration of the Everglades…some positive news from Florida. It was an encouraging article but after reading the whole thing, it still seems to me that climate change will be a continuing disaster for Florida.

Red Tide Rages Along Florida’s Gulf Coast – On a more pessimistic note about the environment in Florida right now…

Top 25 birds of the week: August 2021 – Birds….so many different kinds to see.

Crawling with crickets: the insect swarm in the western US – Mormon Crickets (really katydids) have population crescendos in 3 of every 10 years in the west. The occurrences are patchy but damaging for some crops.

Music in the American Wild – I watched the Missouri Music at 200 webinar this week and am now looking at more of the concert videos from the ensemble. I’ll post the “Missouri Music at 200” webinar video address (when it is available on YouTube). Of course – live performances would be even better. I enjoyed the Hawaii 2020 project videos already…lots of good views of the island (particularly birds and volcanos!).

The ancient Persian way to keep cool – We’ve had quite a few heat advisory days recently…will probably have an increasing number every summer. The world will need to implement the most efficient strategies available to keep people cool.

Camera Trapping As Mainstream Nature Activity – Little cameras in the wild…they are probably less obtrusive than a human being in the place all the time…but not totally benign in every place.

The 'Zoom Boom' Can't Save the Midwest – People are leaving dense, high-cost urban metro areas…but very few of them are going to the heartland.  Maybe some of the areas will benefit from migration because of climate change. Or maybe the Midwest should simply focus on investments to help their economies and create places people want to live….do the groundwork to encourage people to move to the region.

Poison Mushrooms: How to Tell – From the Natural History Society of Maryland…good pictures.

How to keep buildings cool without air conditioning – according to an expert in sustainable design – We are going to need all the technology we know (and some new ones) to keep buildings and homes cool as the planet gets warmer.

America's packaged food supply is ultra-processed: Americans are overexposed to products that are high in calories, saturated fat, sugar and salt -- ScienceDaily – Unhealthy ‘food’ --- most of us have an inkling about this but it doesn’t keep us from indulging. The article mentions the Foodswitch app that allows consumers to scan packaged foods to determine their healthfulness; I loaded the app and scanned things in my pantry. The pasta I buy (whole wheat and green) rates a 5 of 5! Soymilk was 4.5. The canned tamales my husband likes are a 3 (salt and fat).

Thamugadi, a Roman outpost in Algeria, was saved by the Sahara – Buried in sand after it was abandoned around AD 700…and rediscovered in the 1700s but not explored. In the 1870s it was again rediscovered. It was excavated by the French from 1881 to 1960 in its entirety. It became a UNESCO World Heritage site in 1982.

100 days, 100 nights: Sensor network reveals telltale patterns in neighborhood air quality: Custom-built sensors deployed for 100 days and nights to track black carbon pollution -- ScienceDaily – A test was done in West Oakland with new technology to monitor air pollution with more specificity over the area and time of day(s) than has been done before now. The technology worked and demonstrated that the finer grain measurements provide deeper understanding of what impacts localized air quality…something we have to understand to make progress in improving city environments.
