Gleanings of the Week Ending June 11, 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.

Dramatic Short Film Explores the Secret World of Microscopic Plankton – Video and photographs…the beauty of the very small.

“Legacy Pollution” to be cleaned up in seven national parks – I am pleased that it is being cleaned up…chagrined that taxpayers are paying for it rather than the oil companies.

Dandelion chemistry: diuretics and the tires of the future – Redeeming qualities of what we normally consider weeds that are menace! I’ve come to appreciate them more over the years because they are edible (my grocery story has the leaves in their organic section occasionally) and their roots are deep enough to hold soil better than turf on a slope.

Infant formula: the superfood you never think about – One of my grandmothers discovered she was unable to breastfeed her babies….and that was well before commercial formula was available. Whatever recipe she used to create ‘formula’ worked. I suspect that one of the ingredients was evaporated milk. Her 9 children thrived…some into their 90s. What happened in the US recently with infant formula reminds us how dependent we are on modern technology that has become increasingly complex…and sometimes without enough redundancy/alternatives when failures occur.

Ancient tree in Chile could be the world’s oldest – A cypress that could be more than 5,000 years old.

Hot-blooded T. rex and cold-blooded Stegosaurus: Chemical clues reveal dinosaur metabolisms – Honing the analysis of how quickly they could turn oxygen to energy.  

Ancient ochre mine uncovered in Wyoming – Around 13,000 years ago, Paleoindians mined hematite at the site…and used it to produce red ochre.

Photos of the week – May 27, 2002 – Spring prairie flowers/seeds from the Prairie Ecologist.

What can and can’t be recycled – Thinking about recycling….now that I am moving to Missouri, I need to figure out the rules for curbside recycling. I already know there are some differences from Maryland.

Type 2 diabetes accelerates brain aging and cognitive decline – A scary result since there are so many people with type 2 diabetes….and currently doctors don’t have brain based biomarkers for type 2 diabetes or treatment strategies that target neurocognitive declines.

Top 25 Birds of the week: Habitats! – Birds are everywhere (at least now/recent past). The decline in insect populations could make it problematic for many species to survive.

The Institutions of Extraterrestrial Liberty (Day 1: https://tinyurl.com/4t7zjv72 Day 2: https://tinyurl.com/2f9n4b72 Day 3: https://tinyurl.com/48rbba2k Day 4: https://tinyurl.com/5bbey7pr) – A series of webinars chaired by Charles Cockell (I enjoyed his astrobiology course on Coursera back in 2015 and his “Life in the Universe Pandemic Series’ back in Spring 2020). The subject in these webinars is freedom beyond Earth with talks on everything from liberty in Martian settlements to war in space. This is not about the search for life beyond Earth, but it is about the human future beyond Earth and how human societies might evolve over time. The schedule for each of the days is in the comments section so it is easy to select segments easily.

Gigantic flying pterosaurs had spoked vertebrae to support their 'ridiculously long' necks -- ScienceDaily – Their necks were longer than a giraffe’s…and the vertebrae had internal structure not seen in any other animal. The discovery was made with a CT scan and petrographic sections through the bone.  

Linking Birds, Farmer Attitudes and Conservation – The approach is not as straightforward as it might seem…there are nuances and feedback loops that need to be considered to get a positive result.

A breathtaking treasure reveals the power of the woman buried with it : Research Highlights – Early Bronze Age southeastern Spain…heavy silver diadem, silver ornaments…pots with intricate silver plating and daggers with silver-plated handles.

Challenging Conservation Not to Leave Women Behind – An example from the Solomon Islands….globally relevant.

100-Year-Old Lungs Yield Genetic Samples of 1918 Flu Viruses | The Scientist Magazine®- Lungs of 2 soldiers and a civilian preserved in formalin….from the first wave of the 1918 flu…when it was not as deadly as the later waves.

Why Peru is reviving a pre-Incan technology for water - BBC Future – One of the world’s first efforts to integrate nature into water management on a national scale. Projects include protecting high altitude cushion bogs and shoring up ancient water storage (routing water in the wet season to natural infiltration basins). These are ‘slow water’ solutions…mitigations that should be studied for other areas that are drying out as the climate changes.

An Estimated 50 Billion Birds Populate Earth, but Four Species Reign Supreme | Smart News | Smithsonian Magazine – And the 4 species are: house sparrow, European starling, ring-billed gull, and barn swallow.

How humanity has changed the food it eats - BBC Future – Perspectives on the processing of food through our history (and pre-history)…and where we are now. It is still possible to make choices that are healthy for us…but a lot of ultra-processed ‘foods’ readily available that are not.  

Filling a Day of Social Distance – 3/17/2020

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

• Picking earrings to wear that I haven’t worn in a long time. Yesterday I wore some from Orlando FL and today they are from Watkins Glen NY. Earrings are my favorite item to purchase when I travel…small keepsakes that I can wear! Both are over 10 years old, but I still remember where I got them.

• Maintaining the compost pile and walking around the yard. I’m trying to get out of the house at least once a day….enjoy that it is springtime here!

• Watching the second installment of the Cincinnati Zoo’s Home Safari (about Rico the Porcupine). They have established a website where all the videos will be available after they air live. I am watching the recorded version, so I don’t have to pay attention to the time to be online at 3 PM EDT!

• Calling family far away, I had planned to be in Texas this past week…but I was already ‘staying at home as much as possible’ a few days before I was going to get on the airplane. Talking on the telephone is the next best thing for keeping in touch until it is not as risky to be out and about in larger groups of people.

• Making a Zentangle® butterfly. I was straightening up my office and found a few extra butterfly tiles left from last summer’s experience with summer campers. I couldn’t resist using the tile…thinking that this would be a good activity for anyone needing a quiet calm time. If you want to learn a new pattern, checkout out https://tanglepatterns.com/ . Later in the afternoon. it was warm enough that I saw a real butterfly - a cabbage white.

• Watching the 4th video in the ‘Life in the Universe Pandemic Series’ from Charles Cockell - Why didn’t dinosaurs build a space program? His pet gecko, Europa, is part of the lecture too!

Summer Camp Volunteering – week 2

The theme for last week’s Howard Count Conservancy’s summer camps was ‘Fantastic Beasts.’ I spent a morning at Mt. Pleasant and the next morning at Belmont. At Mt. Pleasant there were three groups of campers….45 minutes for each. I used the dinosaur and mammal track rock found at NASA Goddard (saw it back when I was in the HOLLIE program) to initiate the conversation about extinct animals and fossils. There were some fossil shells from Calvert Cliffs and some of the campers had been there to explore themselves. I had on my ammonite shaped earrings too.

Then for some action: Two pans of water, a measuring tape and white board. A person put one foot into each pan (shoes on) and then stepped out and walked normally. The measurement team (usually two campers) measured heal print to heal print to determine the walking stride length. We measured the walking stride of the tallest and shortest in each group (and then everyone else because everyone wanted to know their stride length…or game it and take extra-long steps!). In the oldest group of campers, we measured the running stride (heel first and on toes). It was a great activity to further explore what information can be gleaned from tracks.

We transitioned into evidence of animals living today with some whelk shells and egg cases found on a beach. Some campers were surprised that the whelks were animals that still live in the ocean along the east coast of the US.

One of the junior counselors had participated in a dinosaur dig in Montana…and shared some pictures for her adventure with the campers.

It was a busy 45 minutes!

At Belmont, there were two groups of campers making Zentangle® tiles. I introduced the session using the NASA Goddard rock, the welk shells and my ammonite earrings….and then showed them patterns for beasts. The first group (younger) made octopus/jelly fish and tracks. The second group experimented with an ammonite type pattern, tracks and shells. The theropod tracks were the most popular. Many made some big therapod tracks and then some small ones (moms with babies). A variation from one camper: a therapod track….then a blank area where the therapod flew….then more tracks. One camper made mammal tracks. Both groups enjoyed adding colors after they made their patterns with the black Sharpie ultrafine pens.

Ancient Caribbean children helped with grocery shopping in AD 400 -- ScienceDaily – Snail and clam shells (small ones) might be from child, rather than adult, foragers!

Thousands of Invasive Cane Toads Overtake Florida Community | Smart News | Smithsonian – Ugh! Not something people want in their yards and pools and driveways. These toads have a toxin strong enough to kill cats and dogs that munch on toads and can cause burning eyes or skin irritation in humans.

Top 25 Wild Bird Photographs of the Week: March – National Geographic Society – Beautiful birds….changing environments and habitats.

Where Have All the House Sparrows Gone? – Cool Green Science – House sparrow numbers have been declining since 1966 – all around the world!

Pairing Geothermal Plus Rooftop Solar For A Truly Renewable Home | CleanTechnica – At what point will the idea of geothermal heating and cooling catch up with rooftop solar for our homes? Will Dandelion – or comparable companies - become nationwide?

Five new frog species from Madagascar -- ScienceDaily – Some tiny new frogs. The smallest is only a little larger than a grain of rice.

These pictures of seed bank samples turn biology into art – The beauty of seeds. The first photograph (of Australian windflower flower heads is my favorite. The x-ray of a red yucca seed head is also interesting….showing the 3D of the pod in the image.

HoLLIE – week 2

The second HoLLIE (Howard County Legacy Leadership for the Environment) class day was last week and it was held at NASA Goddard. I was worried about hitting rush hour traffic so left very early since we were to meet in the Goddard Visitor Center parking lot to catch the bus into the facility. The day was sunny and clear…but very cold and breezy. I managed to take this picture of the visitor center (not yet open) without getting out of my car!

The theme for the day was “what informed citizens need to know about earth systems science.” It was the first of two days that our classes will be at Goddard; last week we started with lectures on “understanding the tools and the state of the art in earth science” from the Project Scientist for the AQUA satellite and then got a tour of mission control for several earth science satellites from the Aqua Mission Director. They did a good job of demonstrating the types of data that can be collected, the methods used to collect it, and the ways it has been analyzed. I was surprised to see the LRO (Lunar Reconnaissance Orbiter) mission control in the same building. That brought back the memory of my daughter being on the team to do image calibration shortly after it launched during her undergraduate days!

On the way back to our classroom, we stopped by the replica of the big rock found at Goddard that has mammal and dinosaur and mammal tracks. This was not on our agenda originally but was a wonderful serendipity aspect to the day even if it took part of our lunch time. I’d read about it in one of my news feeds and followed the link to the paper…but it was such a thrill to see the exhibit and hear the short lecture. I managed to take a few pictures.

We started the lectures on ‘understanding the science of earth’s cycles’ that will continue in this week’s class. We talked about the oceans and the carbon system in this second class. One of the interesting videos in the lectures is available online: twenty years of global biosphere data mapped on a slowly spinning globe; it easy to see the annual cycles. With the massive amounts of data, visualization becomes an important component.

When I got home an article in one of my newsfeeds talked about climate models that are developing that explain why there might be a linkage between melting of Arctic sea ice (one of the topics for the HoLLIE lectures this week) and droughts in California (How nuclear weapons research revealed new climate threats). It was easier to understand since I had the background of the lectures!
