The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

• Embedding well-being into curricula for broader, more accessible adoption.

• Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

• Tailoring initiatives to the student body and university culture.

• Securing buy-in from faculty.

• Ensuring new offerings are accessible and don't create additional financial burden for students.

• Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

Registering for a College Class

I registered for a class at Missouri State University last week – Identification of Woody Plants. It has been over 40 years since I did this last! Lots has changed in those years.

• I didn’t need to go through an admissions process ahead of time or get transcripts sent because I am part of the cohort of people over 62 years old that can attend classes at much reduced cost (MSU 62). I called their office a week before the registration day to confirm. I also asked about the pre-req for the class I wanted to take; I had the pre-req in my long-ago college experience but without the transcript, how would they know? I was advised to email the instructor to get a waiver…which I did and they waived the pre-req for me.

• The course catalog and schedule are all online now rather in paper/soft cover books. I knew that there were only 7 slots remaining in the course I wanted to take before I headed to registration.

• The registration for the MSU 62 cohort was held the week before classes started which is later than I usually registered back in the 70s. I arrived just after they opened. The receptionist for the event handed me forms and sent me to tables/chairs to fill them out. The course I wanted to take was not on the paper version of a course list on the tables, so I was glad I had the numbers for it written down to enter in the appropriate places on the form. I also had the printed version of the email exchange with the instructor. I was so focused on the requirements for my degree 40 years ago…now I am just taking whatever interests me and not for credit.

• When I finished the forms, I joined the queue in chairs waiting for advisors…and thoroughly enjoyed a donut while I waited. I don’t remember ever having food provided when I registered for college classes before!

• The advisor got me admitted and registered very quickly. She discovered that I already had a number with the university (maybe because I had donated back in 2020).

• After that I was routed to a second person that printed out my concise schedule and talked to me about setting up my computer accounts, books and parking permits. It appears that the only cost is going to be for the parking pass – quite a bargain even compared to the costs I had in the 1970s. In addition, the textbook for the class I am taking is listed as ‘optional’ so I am waiting to buy it until after I hear what the instructor says in the first session.

Less than an hour after I entered the building, I was walking back to the parking garage. Along the way I photographed the colorful school mascot (bear) at the corner of the building. I am looking forward to this course…not so different from the way I always looked forward to the fall during my education-intense years…but savoring that I won’t be taking any tests!

Then and Now – Universities

My parents prompted my goal to go to college; it was still in my future during the 1960s. At first there was only a vague idea of what universities were like. That begin to change when my mother went back to school so she could become a teacher when I was in junior high. I learned about required courses and textbooks and the library. My sisters and I were in the audience when she acted in a play as part of a drama class. I remember paging through a very thick book for a biology/life sciences class – relishing how much more it included beyond the encyclopedias and schoolbooks I had looked at before. When I started an insect collection for special credit before my sophomore year of high school, my mother took me to the campus bookstore and we bought special black straight pins for the project (there must have been a class at the university that required insect collection too). My collection impression my teacher so much that she asked to keep it!

I was also aware of the protests of the Vietnam War at universities in the 1960s via the news and now with protests of the war in Gaza also via the news. I never was on a campus when one of the more significant protests happened at either time of my life.

Now my perception of universities is based more on first-hand experience from the 1970s and early 1980s when my husband got his PhD and I got my masters, vicarious experience (again) from 2007 to 2019 when my daughter was at 3 universities for undergraduate through to PhD and post doc, my daughter being employed as a professor at a university now, and the prospect of a course each semester at the university beginning next fall taking advantage of the free tuition for citizens age 62 or older.

In the 1960s, the prospect of heading off to the university was all about continuation of my education…preparing for a career…getting the required credits toward a degree. Now, I’ll be taking courses because I am interested in the topic and not ‘for credit.’ Courses that offer field experience or labs will be my primary focus…things that I can’t get in an online format or from a book. The first course will likely be a field course identifying woody plants; the second might be geology course which includes field trips and a lab; the next one might be pottery making!

In the 1960s, I was oblivious to the administration of universities. In retrospect, there were a lot less non-faculty staff at universities in the 1960s. And those non-faculty people often get higher salaries than the faculty; they are largely responsible for the cost of university education increasing faster than costs in just about every other sector. And those non-faculty people make decisions about how funding cuts will be made so their ranks will never go down! How does bloat in a university’s administrative staff ever get trimmed?

It seems that universities are changing very slowly compared to the rest of society. There is a paradox of research that is often leading edge coming out of an organization that incorporates processes that are almost like hazing (qualifying exams for graduate students that are traditionally ‘failed’ the first time through…committees of other faculty members that review tenure track packages and provide negative feedback, sometimes not factual and sometimes personal rather than relevant to the position…minorities and women judged harshly).

The role of universities is not as clear now as it seemed to me in the 1960s. I’m not sure if that is true because I know more about them now or if they have not changed in the intervening years in ways that they should have.

Gleanings of the Week Ending March 19, 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.

Can cloud seeding help quench thirst of the US West? – New research on an old idea…many states increase their use of the technology.

Fresh water from thin air – Another technology that might help dry regions….using hydrogels (like the ones currently used in diapers!).

What’s The Construction Industry Blueprint to Cut Carbon? – I wanted more specific examples…was a little disappointed that this article did not provide them, but maybe that would have made it a long article! I hope to see more on this topic.

Higher education must reinvent itself to meet the needs of the world today. Enter the distributed university – The pandemic has highlighted the challenges the current higher education model is facing. The ideas in this post are a start but don’t seem to be fully developed to push into full implementation. More work needs to be done to enable transition from the existing model to a new one that is more responsive to the needs not only of undergraduate students but for graduate students and continuing education. The sources of money in the current model don’t match up well. For example – in the US the sports programs (football) is a big money maker for many universities; how does that map into the new model (or do we want it to).

Upcycling plastic waste into more valuable materials could make recycling pay for itself – Hope this research can be transitioned into commercial use….we have to improve the recycling processes that are being used today. Too much is still ending up in landfills.

Fossil pollen reveals the African origins of Asia’s tropical forest – Research on Borneo’s Dipterocarps (very large trees with buttress roots, smooth/straight trunks, high crown) using fossil pollen reveals their origins in Africa…spread through India before it crashed into Asia…and then to Southeast Asia. The forests in India shrank as the climate became drier. These trees need a wet, seasonal climate to survive.

Mummification in Europe may be older than previously known – Analysis of bodies found in Mesolithic shell middens in Portugal reveal that they were probably mummified before being placed there 8,000 years ago. The description of the way the researchers came to that conclusion was interesting…a lot has been learned about forensics since the 1960s when the bodies were originally found. The oldest intentional mummification known before this finding was from the Chinchorro hunter-gatherers living in the coastal region of the Atacama Desert in shell middens (around 7,000 years old).

Lake Powell Reaches Lowest Level Since 1980s – The drought continuing in the west….

The myths and realities of modern friendship – Thought provoking. The ways we communicate with each have changed a lot over my lifetime!

The climate math of home heating electrification – The rationale for moving to heat pump heating/cooling as quickly as possible.
