Top 25 birds of the week: Birding! – Wild Bird Revolution  - And I want to travel to some birding festivals too!

Recycled concrete could be a sustainable way to keep rubble out of landfill: Can even outperform traditional construction, says researcher – ScienceDaily – A Canadian study…seems like the results should be pertinent to the US too. The research indicates that “recycled concrete can be a 100% substitute for non-structural applications”….and might also be a substitute within more structural applications as well if innovations in the composition of recycled concrete continue.

Top 10 States For Renewable Energy, & Their Renewable Energy Splits  - Interesting mix of states on the list with quite a difference in the amount of hydro, wind, solar, geothermal, and biomass among the top 10. California is the only one with all 5. But there are 5 states that have 4 of the 5.

Take a Virtual Tour of the World’s Largest Circular Tomb, Augustus’ Mausoleum | Smart News | Smithsonian Magazine – The virtual tour takes a little bit to load….but is worth it. Note that the ‘chapters’ are along the bottom of the screen.

Desalination breakthrough could lead to cheaper water filtration – ScienceDaily – Increasing efficiency of reverse osmosis filters by beginning to better understand how they work. This is something that will be more important as climate change and our own production of pollutants makes obtaining clean water more challenging.

Unique Activities for Yesterday:

3 racoons. Our birdfeeder camera made a video of some visitors to our deck just before 2 AM on Wednesday, 8/5: three racoons! They looked smaller than the female that came several times earlier in the summer. Perhaps they were her young….out foraging on their own (maybe she was nearby). They were no more successful than she was getting seed from our squirrel proof birdfeeder! The action started with one up on the deck railing under the feeder and another 2 directly below on the deck floor. The one on the railing comes down almost on top of one that was on the deck floor. The one that was on the deck railing stayed in the video the longest…thoroughly searching under the feeder after going down to the deck floor.

Sycamore branch. Back on August 2nd I posted about a dead branch in our Sycamore tree (picture on the left). My husband discovered the branch on the ground near the base of the tree when he went out to use the weed eater and it took both of us to pulled it to our brush pile at the edge of the forest. It came down without bringing a lot of other branches with it….a little sooner than I expected but probably brought on by the thunderstorms that have been sweeping through the past few days.

Yellow wooly bear. My sister sent me a picture of a caterpillar from her garden in Carrollton, Texas. It appears to be a yellow wooly bear that becomes a Virginian Tiger Moth. Evidently, they are common but neither one of us had seen one before.

Ten Little Celebrations – July 2020

I’m celebrating that everyone in my family is healthy and staying vigilant. We’re all in states that have a growing number of cases, though. As usual – I am looking back of the month and highlighting 10 little celebrations.

Large Monarch caterpillar. Toward the end of the month, there were caterpillars on the milkweed in our front flowerbed. One morning I walked out and saw a large one almost immediately.

It was eating way…probably getting close to the size to pupate. I’ll look around for the chrysalis in the bushes nearby in a few days.

Cantaloupe in the CSA share. Yummy melons…one of the best foods of summer.

Regenerative landscaping webinar. Sometimes a webinar just comes at the right time. This one had so many interesting ideas. The one that I’ll probably try first is over seeding with mini-clover instead of grass seed in the thin places of our yard.

Morning hour on the deck. I love the quiet time on the deck first thing in the morning. I enjoy my morning caffeine, create a Zentangle tile, read a little….usually with our cat as company.

Neighborhood pond in the morning. Lots of interesting things at the pond --- different every time…birds, turtles, plants, insects.

Milkweed. Blooms, pods, insects (milkweed bugs and beetles, aphids (aargh!), Monarch caterpillars). The plants are little worlds of activity.

Summer sunrise. It’s getting easier to get up and out to catch the sunrise.

Mt. Pleasant. Venturing out just a little…early enough that there are not very many other people around.

Western Regional Park (Howard County, Maryland). A place I hadn’t been before but worth discovering.

Goldfinches. Looking out the window at the right time.

Unique Activities for Yesterday:

NOAA Get into Your Sanctuary! Events. There was a post on the NOAA feed about this; relatively short notice but maybe ‘just is time’ is good enough. The events are live 7/31-8/2. I am planning to watch as many of them as I can. https://sanctuaries.noaa.gov/visit/giys.html

Observations at the grocery store. When it got to the grocery store, the sun had only been up for about 10 minutes, so the short drive was scenic with the glow of morning light. As usual – there weren’t very many people in the parking area or in the store and everyone was wearing masks. I noticed that most masks were similar to mine but there two outliers: a woman that was wearing something that looked more like a gas mask and then a shield over that and a staff person that was wearing a mask that looked like it was very thin (had been through a lot of washings).

There was a sign saying that the carts were sanitized when I approached the area to get my cart – so I didn’t wipe the cart down again but did use the hand sanitizer station for my hands.

Things seemed well stocked although some of the store brand products we bought previously have not been replenished; the more expensive ‘name’ products are available.

I am enjoying the SCAN app my store provides. My bags are loaded as I shop (in the way I want them) and the checkout is as close to contactless as one can get inside the store! I wonder if all grocery stores will develop this kind of app for their customers.

Filling a Day of Social Distance – 4/17/2020 - Gleanings

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

Here are the unique activities for yesterday:

Browsing through some issues of Vogue. The Internet Archive has some issues of Vogue online. I particularly enjoyed the one labeled Vol 138: Vogue which includes issues from October - December 1961 (a bound reference volume); you’ll have to create a free-sign on to check it out – browse through. I was in 2nd grade when these issues were originally published and the designs appealing; maybe we all have a subconscious affinity for clothes that were worn as we were growing up. It was a time when natural fiber fabrics were being replaced with synthetic fibers. I can remember learning to iron my cotton shorts and tops during the summertime when I was in the later grades of elementary school!

Noticing filaments algae in the sycamore branch vase. How did it get here? Were there spores on the branch when I brought it in? The picture on the left below is looking down into the vase, the branch being the diagonal shape in the lower left corner. I pulled some algae out and put it on the top of my iPad (using the iPad as a light table) and took a picture through the jeweler’s loupe (picture on the right)…not enough magnification to see any internal detail, unfortunately.

Can fashion ever be sustainable? - BBC Future – This article fit right in with the Fashion as Design Coursera course I am working my way through right now. I already buy more than half my wardrobe from thrift stores and don’t buy very often. My closet is still too full; one indication is recently finding a pair of jeans I had forgotten about! This article has prompted me to think about how often I wash my clothes. Maybe I don’t need to launder some of them as frequently.

Why This Rare, Huge Ozone Hole Over the Arctic Is Troubling Scientists | Smart News | Smithsonian Magazine – It probably will close soon – but it’s an interesting phenomenon that probably would have gotten more press if coronavirus wasn’t overwhelming all other news.

Blood test detects over 50 types of cancer, some before symptoms appear -- ScienceDaily – This type of test has been a goal for years. Are we getting closer to reality?

Covid-19: The history of pandemics - BBC Future – The impact of coronavirus on our day to day lives is a unique experience for most of the world’s population. This article is a short history of  other pandemics: Justinian plague (6th century…killed as many as 50 million which was half the global population), the Black Death (14th century…killed up to 200 million), smallpox killed as many as 300 million people in the 20th century alone even though there was an effective vaccine available since 1796, 1918 influenza (50-100 million died), and HIV (killed 32 million and infected 75 million with more added every day). Since 1980, the number of outbreaks of new infectious diseases per year has tripled.

19 Incredible Winning Photos from Nature Photography Contest – Lots of interesting nature photos.

Wearable device lets patients with type 2 diabetes safely use affordable insulin option -- ScienceDaily – Maybe technology can deliver less expensive drugs in news ways….making the drugs more effective.

New Research Shows Healthy Agriculture Means Healthier Birds – Honing our understanding of healthy agricultural schemes that promote healthy farmland birds.

How cutting your food waste can help the climate - BBC Future – Over the past few years, I have started composting and reduced my food waste by eating food – never forgetting what I have in the refrigerator. Keeping a mental inventory of fresh fruits and veggies…freezing anything that I might not use before it goes bad….has been key. I enjoy frozen bananas in smoothies more than the unfrozen! This time at home (social distancing) gives me an opportunity for another round of reducing food waste….although it’s harder now since I’ve done all the easy actions.

'Grand Challenge' review stresses global impact of microplastics -- ScienceDaily  - Where major research and discovery are needed re microplastics impact on the environment and health. Recognizing that all plastic is not the same and new tools will be needed.

Traveler Special Report: Threatened and Endangered National Parks – In Alaska and beyond…we are losing the natural treasures we sought to protect.

The history of candy canes and why they taste so cool – I am late getting around to including this in the gleanings list. I like peppermint candy year round…even if it’s not in the candy cane shape! I have peppermint candy chips to use in snow ice cream…if it will ever snow enough this winter here in Maryland!

Largest Electric School Bus Program in United States Launching in Virginia | CleanTechnica – Dominion Energy partnering with Virginia School districts…to achieve a 50% electric school bus fleet by 2025 and 100% by 2030. Good for the environment and the lungs of Virginia’s school children. I hope other states will move in the same direction.

Offshore Wind Has the Potential to Fulfill Global Electricity Demand 18 Times Over - Yale E360 – Hurray for this potential….the transition is the challenge.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live.

New Ultima Thule discoveries from NASA's New Horizons -- ScienceDaily – A space mission to something we’ve never seen before….the aptly named ‘New Horizons’

Why are biology classes ignoring insects? · john hawks weblog – When I was in high school, insects were a big deal for biology classes; many students created an insect collect the summer prior to the biology year. I don’t remember too much about insects in my first courses as an undergraduate in biology I the 1970s…but there was probably more coverage than in the more recent textbooks.

Keeping fit: how to do the right exercise for your age – A good summary…although the key message is to keep moving…sustained exercise is the best strategy.

Our bodies may cure themselves of diabetes in the future -- ScienceDaily – It’s at the basic research level…but could be an approach to ‘diseases’ caused by cell death in the future (diabetes, Alzheimer’s and cells damaged by heart attacks, etc.)

Researchers have discovered how to slow aging: Natural product found to reduce the level of damaged cells in the body, caused by aging -- ScienceDaily – I never know what to think of these early findings…but the logical take away from this one is eat fruits and veggies since that is the source for Fisetin. But – that’s been dietary guidance for a long time.

Belly Fat Has a Role to Play in Fighting Infections | The Scientist Magazine® - Research is yielding some functions of the omentum…but there is still a lot to discover about the role this organ plays in the body.

Recovery: Prairies Under the Sea – Cool Green Science – Eel grass recovery…a success story close to where I live. The success with sea grass restoration in Tampa Bay faced a setback with this year’s red-tide blooms.

Keep your salad greens safe | Berkeley Wellness – I agree with everything except the ‘bag them’ since I am trying not to get any plastic bags at all. I take a bin with me to the grocery store for wet items and use mesh or paper bags for the dry items. And make sure the meats are in a separate bag from my produce at the checkout.

Voyager 2 Detects Hints That Interstellar Space Is Nearby – Launched in 1977, Voyager 2 is getting closer and closer to leaving the solar system.
