Gleanings of the Week Ending January 25, 2025

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

How Will Climate Change Affect the Spread of Invasive Species? - The silver lining of knowing humans are still one of the main drivers of invasive species spread, is that humans can also curb invasive species spread. We can plant native plants in our yards and gardens instead of ornamentals from other states and countries. We can clean our boots, shoes, fishing waders and boats when we travel from one area to another, and we can stop releasing unwanted pets into local parks, ponds or creeks.

Kangaroo species went extinct in the Pleistocene - Nearly two dozen kangaroo species vanished in the Pleistocene. If things get warm enough, dry enough, kangaroos today are going to have a tough time making it, regardless of whether they're mixed feeders.

Medieval Crowns and Scepters Discovered Hidden Inside the Walls of a Crypt Beneath a Lithuanian Cathedral – It had been hidden for 85 years—since it was stowed for safekeeping beneath the Vilnius Cathedral in southeastern Lithuania - put there at the outbreak of World War II in 1939.

Your work habits may be threatening your sleep - Sedentary workers experience a 37% increase in insomnia-like symptoms. Employees working nontraditional schedules experience a 66% greater risk of needing 'catch-up sleep.' It’s more about how jobs are structured and staffed than individual ‘habits.’

Renewables Supplied Two-Thirds of Germany’s Power Last Year - In Germany the solar buildout continues to surpass government targets, with solar now amounting to 14 percent of power generation. Wind remains the biggest source of clean electricity, accounting for 33 percent of generation, though new wind farms are being developed more slowly than planned. Along with new renewable power plants, Germany is seeing a growth in battery storage as homeowners install batteries alongside rooftop solar panels.

Why just two hours of exercise a week can be life-changing - One retrospective study of over 37,000 people found those who did their week's worth of physical activity over just one or two days had the same reduction in cardiovascular disease risk as those who did activity spread throughout the week.

Lead pollution likely caused widespread IQ declines in ancient Rome, new study finds - Scientists used Arctic ice core records to reconstruct historic atmospheric lead pollution in Ancient Rome and link exposure to cognitive declines. Ancient lead pollution stemmed largely from silver mining, whereby the lead-rich mineral galena was melted down to extract silver. For every ounce of silver obtained, this process produced thousands of ounces of lead -- much of which was released to the atmosphere. In the 20th century, lead pollution predominantly came from the emissions of vehicles burning leaded gasoline.

A Half Mile Underwater on Connecticut’s Eight Mile River - Designated a Wild and Scenic River. Black rock geology and tannin in the water take most of the light making visibility to a snorkeler limited.  Caddisfly larvae, mussels, Chinese snails (invasive, aquarium escapees), musk turtle, white sucker, common and spottail shiners, sea lamprey (a native here, unlike in the Great Lakes), redbreast sunfish.

Gleanings of the Week Ending June 22, 2024

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

Life in a heat dome: The American West is figuring out how to keep cool – Summer in US cities…strategies to mitigate the hotter temperatures caused by climate change.

Statins for heart disease prevention could be recommended for far fewer Americans if new risk equation is adopted – Not a lot of details in this article although I have suspected for some time that statins were being over-prescribed.

10 States Where the Gas Tax Is Highest – This post prompted me to compare gas taxes in the states I drive through to on my frequent road trips to Dallas (Missouri, Oklahoma, and Texas)…and the decision to always buy the tank of gas required in each direction in Oklahoma!

Creating a throw-away culture: How companies ingrained plastics in modern life – Aargh! Despite growing public pressure, companies increased their use of new plastic by 11% between 2018 and 2022!

What happens when you take too much caffeine - When we consume caffeine, it's quickly absorbed into our bloodstream, where it out-competes adenosine by preventing it from connecting to these receptors and doing its job to make us feel tired. This is why consuming caffeine can make us feel more awake and alert. Caffeine can also boost levels of other neurotransmitters like dopamine and adrenaline, which can make you feel more stimulated. Research has associated caffeine consumption with up to a 60% reduced risk of developing Alzheimer's. One explanation for this is that caffeine improves blood flow to the brain. While caffeine enters the gut quite quickly, its effects can take hours to wear off. Scientists recommend having your last 'dose' of caffeine eight hours and 48 minutes before you go to bed.

Why do 1 in 10 Americans get eczema? Is it too much salt? - Eczema, also known as atopic dermatitis, is a chronic disease that causes dry, itchy skin. It's one of the most common skin conditions, affecting more than 31 million people in the U.S., and one in 10 people will develop it at some point. It has become increasingly common in recent years, especially in industrialized countries, implicating environmental and lifestyle factors like diet.

A fierce battle is being fought in the soil beneath our feet – and the implications for global warming are huge - In some parts of the world, increased CO₂ means tiny bugs in the soil “hold onto” their phosphorus, making less available for trees.

Rock Art Found in This Saudi Arabian Cave Offers ‘Rare Glimpse’ Into Ancient Human Life – Sheep, ibex, and goats on the walls of a lava tube.

Depressive symptoms may hasten memory decline in older people – 16 years of data from 8,268 adults with an average age of 64. This study shows that the relationship between depression and poor memory cuts both ways, with depressive symptoms preceding memory decline and memory decline linked to subsequent depressive symptoms. So – interventions to reduce depressive symptoms might slow memory decline.

D-Day shipwrecks were a WW2 time capsule – now they are home to rich ocean-floor life – 80-year-old wrecks that line the coasts of Britain and France…reclaimed by sea life.

New Orleans Vicariously

My daughter attended the American Astronomical Society meeting in New Orleans last week with her research students. She sent a few pictures of the place that reminded me of the two visits I made to the city years ago…and something added to the skyline more recently.

She took a walking tour of the French Quarter…and took a picture on the river as it ended around sunset.

The next day she photographed the sunset from her hotel window. Her room was on an upper floor and the window was grubby…but it made the picture look ‘painterly.’

The second picture (only a minute later) highlighted a strange shape with a blue light on the horizon. It looked like a spy plane at first glance! I did some research. It is the Bollinger Canopy of Peace that spans across The National WWII Museum’s campus…built after 2015!

The next day my daughter and her students (and some others from the conference) did a late-in-the-day visit to the Audubon Aquarium in New Orleans. It was established in 1990 – long after my last visit to New Orleans for a Computer Measurement Group meeting in December 1981 (the first visit was in Fall 1977 for a King Tut exhibit).

It was fun to get her impressions of the city. A lot has changed in over 40 years, but the French Quarter is still the hub – hotels and museums and walking tours cluster around it. I also savored that both of us have the experience of traveling to interesting places as part of our careers.

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.
