Library Adventures – June 2024

My most frequent interactions with my local library are digital…checking out Kindle books. In June, there were 3 interactions that were not digital at all!

The first one was volunteering at one of the branches with the Friends group used book sale. It was a smaller branch and was only a one-day event. I helped with the set-up the day before and then with the first hours of the $3/bag sale. There were quite a few people that stopped by and left with 1 or more bags of books and the Friends netted $295 from the day. My favorite was an elementary school aged boy that came in with his mom and picked out two bags of books; he was very pleased with his haul and shared that he might share some of them with his older brother.

The second interaction was an art class that was announced in the monthly library newsletter. It was free…held in the early evening…2 one-hour sessions over 2 weeks. It was scheduled in the branch library closest to where I live. I signed up. We made a color wheel the first session and then did shades of the same color (by adding white) on the same small canvas in the second.

I took a picture of the plate I used to mix the paint for the shades of ‘red’ in the second class.

The next day I made Zentangle patterns over the white space of the canvas (and into some of the painted areas as well).

The class was a good learning experience. 1) It was my first experience with acrylic paints…and I realized that I enjoy the pens and Zentangle too much to make time for paints! 2) Canvases are not smooth enough for pens. I used a Sharpie Ultra-Fine pen and it was hard to control the tip of the pen over the bumps of the canvas fibers.  3) A free class is a low-risk way to try something new!

The third interaction occurred when we had a form that required notarized signatures. My husband found out that the library had a notary so we took our form there and indeed the person at the desk was a notary – it was very easy!

 Positive interactions at the library….it’s more than just a place to check out books!

Gleanings of the Week Ending January 14, 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.

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!

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.

America’s largest transit bus charging station & microgrid open in Maryland – The headline caught my eye because I lived in Maryland for over 20 years – 8 of those in the county where this is happening! I hope other states have the same sorts of projects in the works.

NASA Finds More Than 50 Super-Emitters of Methane – Finding them is only the first step….how many of them will be situations we can reduce or stop the emission?

Iron induces chronic heart failure in half of heart attack survivors – This study prompted testing of iron chelation therapy to remedy or mitigate the effects associated with iron in hemorrhagic myocardial infarction patients.

Unique Bronze Age belt discovered near Opava – Half my ancestors came from the area that is now the Czech Republic…I am drawn to articles about the history of the region.  The belt is quite beautiful…but was it a practical item of apparel?  

What happens if our circadian rhythms are out of whack? – WHO has proclaimed that disrupted circadian rhythms are a probable carcinogen. The study discussed in this post was about the mechanism that circadian rhythm disruption triggers lung tumors.

View 16 Breathtaking Images from the Nature Conservancy’s Annual Photo Contest – Take a little break….look at awesome images of our world.

Mississippi River Basin adapts as climate change brings extreme rain and flooding – This year the stories about extreme weather seem to be more frequent – and wide ranging in terms of water. The Mississippi was low enough for barge traffic to be impacted because of drought…yet there were floods along part of the river just last summer.

Eye-opening discovery about adult brain's ability to recover vision – An unexpected success…opening new ways to treat a vision impairment (LCA) and maybe prompt a re-look about how the adult brain can re-wire itself relative to vision.

The World’s Whitest Paint May Soon Help Cool Airplanes and Spacecraft – A way of making paint that was previously too thick/heavy for things that move. The thicker version works for homes and buildings. We’ll need this technology to reflect heat without expending energy!

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.

Gleanings of the Week Ending January 18, 2020

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.

Earth at Night – This is an eBook from NASA that was last updated in December 2019….lots of pictures of the earth at night, analysis, and the technology behind the images.

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.
