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.

See the Rancid, Blooming Corpse Flowers Attracting Hundreds in California – Seeing pictures is good enough for me!

Global diet study challenges advice to limit high-fat dairy foods – Some dietary advice is more impactful that others. New studies show that dairy, particularly whole fat, may protect against high blood pressure and metabolic syndrome.

Dust From the Drying Great Salt Lake Is Wreaking Havoc on Utah’s Snow – Dust makes the snow less white…which means it warms more quickly and melts!

Early Medieval Ivory Pocket Ring Analyzed – The ring was found in the grave of a wealthy Anglo-Saxon woman near Sheffield, England…and it was made from the tusk of an African elephant!

Parts of a Munich synagogue demolished by Nazis are found in a river 85 years later – The site of the synagogue is a parking lot and department store now. About 150 tons of stone columns and a tablet bearing the Ten Commandments were found about 7-8 miles from the site in a river. The synagogue had been built in the late 1800s and had more than 1,500 seats. It was destroyed in 1938.

Cosmetic chemical concerns – Not an exhaustive list/explanation, but worth browsing…there are others that seem to be concerning too (such as sulfates) that manufacturers are saying their products are eliminating.

Astro-tourism – chasing eclipses, meteor showers and elusive dark skies from Earth – We did a trek to Nebraska for the 2017 eclipse…have enjoyed Staunton River State Park Chaos Star Parties. My husband has been to Greenbank and Cherry Springs State Park for similar amateur astronomer events. It would be great if there were more such events but there are fewer people interested (and able to afford the equipment) than birders. Hopefully some of the dark sky sites will enlarge their offerings beyond outreach events for individuals that would like places to set up their own equipment. On the plus side – there are solar eclipses come up!

Native Bees Yield Hardier Flowers Than Honey Bees, Research Finds – When pollinated by native bees, plants produce more diverse offspring….and diversity is increasingly important as our climate changes.

Frogs as pollinators – A previously undocumented interaction…and an example that there are still aspects of the natural world to be discovered.

Older adults who remain more active have a better quality of life, study finds – Not really a new idea…but a study that tried to quantify the impact.

New Mexico Dreaming

/

My daughter had a conference in Albuquerque, NM in June…took advantage of a tour to the Very Large Array (astronomical radio observatory) offered. She sent two pictures.

And started a whole sequence of thoughts about traveling to New Mexico again. The last few times (pre-COVID) were for Festival of the Cranes at Bosque del Apache National Wildlife Refuge in the fall/early winter; they included a lot of birding field trips around Socorro, NM plus tours of the VLA. Prior to that we made vacations that featured Sandia Peak, Chaco Culture National Historical Park, El Malpais National Conservation Area, and Bandelier National Monument. As early as the 1970s, we took road trips from Texas to New Mexico….to Santa Fe, Taos, Los Alamos, Albuquerque.

Now we live close enough to enjoy a road trip to the state. I’m contemplating a loop that would start with an almost straight drive from Missouri across Oklahoma to Albuquerque…and come back through Dallas. Between the long drives…a lot of shorter drives to see areas we’ve been to before and maybe some that we haven’t too! We’ll wait for the temperatures to cool down…and maybe for the birding festival event…to make the trip.

Settling in, developing new routines – 8th month

/

We moved to Missouri eight months ago and have adjusted in many areas…but there are still things to do. My previous ‘settling in’ posts were made in the 1st, 2nd, 3rd, and 4th month; it’s time for another update. The upheaval of the move is waning. The changes between our 4th month and now are more gradual; there isn’t the frenzy of activity like in the first few months. We’ve voted in the mid-term election, subscribed to a local news feed… are experiencing winter and working on our 2022 tax filing (it is more complex this year with the sale of a house and two state taxes). I’ve sustained my treks to Texas; it’s become apparent that the monthly plan might need to be adjusted quickly depending on the care my parents need; the priority of being available for my parents will keep me from signing up for volunteer gigs or university classes. Our three kittens are keeping us close to home too; they need a lot of attention but we have successfully done day trips and 1-2 nights away; my daughter checks on them when we are gone for more than a few hours.

There are still things we are anticipating:

Spring in Missouri. The rhododendron flowers were already fading by the time I first looked at the house…the irises had already bloomed too. I’ll enjoy seeing the flowers…supplemented with the additional bulbs I planted last fall. We are also talking about day trips for gardens and birding hotspots within the state.

All-electric. We are talking more about the order of steps we will take to move the house toward being ‘all-electric’ over the next 3 years or so…and then adding solar panels/battery.

Dark sky. My husband is keen to go to a dark sky site…hopefully once the temperature is a bit warmer, he’ll be able to do it.

Yard. I have been putting off contacting a nursery…but need to do it soon if I want things in before it gets too hot (and potentially dry) this summer.

Overall – we are not venturing out very much right now because of the cold…but we’ll do more outdoors in the spring. And maybe meet more of our neighbors too!

A 50th Anniversary

/

I posted about my parents’ 70th anniversary back in December; now I am celebrating my own 50th wedding anniversary with my husband. The anniversary prompts me to think about those 50 years of shared life from different perspectives.

Our external focus shifted through the years:

  • For the first 10 years, we were completing our education – a PhD for him, a masters for me. I was working full time during those years…not thinking about computer science as a career for the first 5 years but gradually realizing that I liked the work too much to switch fields. From the beginning he seemed to have a clearer idea of what he wanted to do. We were the first in both our families to go beyond an undergraduate degree.

  • We moved to the east coast for my husband’s work; it was a great career move for me too. We were both focused on our careers for about 5 years.

  • Then we decided to have a child and took the precautions needed for a successful pregnancy in our mid-30s. We thought we were prepared when our daughter was born but quickly realized that there was a learning curve that was just beginning. Between the two of us we successfully juggled parenting and careers…until she went off to college 20 years later.

  • There were 5 years of career focus with occasional bursts of activity to help my daughter move out of the dorm into an apartment, get to an internship, or move for graduate school. The internship and graduate school were more than halfway across the US!

  • 10 years ago - I retired and my husband started a ramp down from his career that continued for several years.

We’ve lived in several states over the 50 years: Texas for 10, Virginia for 3, Maryland for 36.5, Missouri for .5 years. The two long haul moves (from Texas to Virginia and from Maryland to Missouri) were quite different. We had a lot more household items to move the second time, the technology of finding a new house/selling our old one had improved dramatically, and we were able to buy our current house rather than get a mortgage.

Our shared interests have evolved over the years.

  • Photography. My husband was the one that enjoyed photography from the beginning….doing his own black/white and color developing (and printing too). I remember in our first house when one of the developing chemicals was not diluted enough when he poured it down the kitchen sink and it dissolved the disposal flaps! We have a lot of negatives and slides from those pre-digital years. The transition to digital happened about the time our daughter was old enough to start taking pictures. My interest in photography picked up a little when my daughter was born but ramped up dramatically once I retired.

  • Travel. From the very beginning we’ve both enjoyed day trips and vacations to outdoor destinations: gardens, state parks, and national parks. In the beginning, we economized by car/tent camping and not eating out. By the time we moved to Virginia we could afford flying, staying in hotels, and eating out although the road trip still dominated our vacations. When my daughter was born, we shifted our accommodations to ones that had a small kitchen to accommodate her food requirements/preferences. Some of our travel was associated with either my career or my husband’s…so that part of the travel was paid for as part of our work. After she got older and as we travelled more on our own, we enjoyed short term house rentals. For a few years before the COVID-19 pandemic, my husband and I used birding festivals as a focus for our travels.

  • Astronomy. My husband was interested in astronomy before I knew him. One of our early dates included a lunar eclipse at the local astronomy club’s observatory. In the early years of our marriage, we participated in grazing occultations (stars and the mountains of the moon); my role was to help him get the telescope set up as quickly as possible in the assigned location so he could take the measurements. Later I used the cast iron telescope mount to add weight in the back of my rear-wheel drive car – to give it more traction on snowy days in Virginia. His astronomy activity ebbed although he did replace his telescope; we (daughter included) observed the sunrise in 2000…our celebration of the new millennium. Once he retired, he became active the local astronomy club in Maryland and we both camped on the field for a star party at a dark sky site in Virginia several times; he liked the dark sky (and being able to call it a night whenever he got tired) and I enjoyed being outdoors, hiking during the day.

A lot has happened in 50 years and we’re both realizing how fortunate we are that the big decision we made all those years ago was a good one for both of us!

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.

H5N1 Bird Flu Detections across the United States (Wild Birds) – A map of US counties where bird flu has been detected in wild birds as reported by the US Department of Agriculture.  It would be great if data could come from the National Wildlife Refuges (reporting through the US Department of the Interior) since they often have concentrations of wildlife and staff that would be monitoring the flocks. I know that there were instances of bird flu – primarily in snow geese - that the Bosque del Apache NWR staff were reacting to when we were there the November before COVID-19 curtailed our travel.

Electric car sales drive toward cleaner air, longer lives – Another reason my next car will be an electric rather than a plug-in-hybrid that I have now. However – this should probably be seen as an offset to the negative impacts on public health that climate change will bring; the air could be cleaner, but it will also be warmer and more turbulent. I am becoming less certain that my lifespan will last into my 90s like it has for my parents.

Living the lava life on Mauna Loa – A satellite image from NASA’s Landsat 9. It shows how close one of the flows came to Hawaii Space Exploration Analog and Simulation (HI-SEAS) project habitat. Fortunately, the most recent mission there concluded in May 2022.

The Dead Sea is dying – The lowest exposed place on Earth…water level dropping 4 feet per year…salt formations and sinkholes.

Beyond cola: the strange flavors of soft drinks – Carbonated drinks were invented by Johann Jacob Schweppe in 1783. They were sold in glass bottles and that were recirculated. Regional delicacies. Everything changed with the advent of plastic bottles in the 1970s. Moxie, state beverage of Maine, continued independently for a long time – bought by Coca-Cola in 2018. Soft drinks had a heyday in the years of Prohibition. Follow the link for the whole article, more soft drink history.

Construction of the world’s largest radio telescope begins – Square Kilometer Array (SKA) – one in Australia and one in South Africa. Construction will be completed by the end of the decade, but observations will begin in 2024.

Flameproofing lithium-ion batteries with salt – Finally….hope this solves the fire problem with lithium-ion batteries and, if so, moves into new battery manufacturing quickly.

The 120-year search for the purpose of T. Rex’s arms – A little history of T. Rex finds…and the various ideas about why the animal had such puny arms.

A new weapon against antibiotic-resistant bacteria – Work to find a new treatment for Klebsiella pneumoniae infections that are resistant to common antibiotics with some strains fatal for 40-50% of infected people. A new strategy: weakening bacteria with an existing drug previously used to treat herpes that alters its surface layer to make it easier for the immune system to kill the bacteria. The idea works in the research model…effectiveness in human beings yet to be confirmed.

The science of why hawks are one of nature’s deadliest hunters – Birds and bats….The birds steer toward a fixed point in the swarm instead of singling out a bat. It’s a good strategy against a gathering of prey!

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.

An effective new treatment for chronic back pain targets the nervous system – A 12-week course of sensorimotor retraining had a positive effect and participants reported improved quality of life one year later (i.e., the relief was lasting). Hopefully the results can be replicated, and the treatment applied to a broader population. There are a lot of people with chronic back pain!

New Study Links Cat Hormones and Gut Microbiomes to Their Social Behavior – Hard to resist a cat story!

Millions of Americans have long COVID. Many of them are no longer working – 4 million full-time equivalent workers out of work because of long COVID (conservative estimate…and that 2.4% of the US working population). There is a push to provide accommodation in the workplace but some of the symptoms are so severe that the person cannot perform the work they did before and maybe too disabled to work at all. No wonder unemployment is low, and some jobs are not finding applicants. Because long COVID is new, it is unclear when, or if, this population will recover enough to re-enter the workforce.

Arche Roach: the great song man, tender and humble, who gave our people voice – An obituary – and history of aboriginal people in Australia over the past century or so.

The promise and danger of Scotland's bog – 80% of the UK’s peatlands are degraded and in deteriorating condition. They store a lot of carbon…motivating restoration efforts. It takes decades to reverse damage done in a short time by a few ditches and a grid of planted saplings.

New molecule may prevent age-related diseases and increase life expectancy and wellness – A group of molecules that enable cells to repair damaged components has been identified….and efficacy was demonstrated in a model organism. The researchers and Hebrew University’s tech transfer company are moving toward pre-clinical studies.

Parts of the moon have stable temperatures fit for humans – Pits and caves that stay roughly 63 degrees Fahrenheit! There are still big challenges for living on the moon: growing food and finding sufficient oxygen, for example

Coming wave of opioid overdoses 'will be worse than it's ever been before' – Fentanyl and carfentanil…combined with methamphetamines and cocaine. The accelerated rates of overdoses are happening everywhere according to a Northwestern Medicine study.

Inside King Tut’s Tomb – New research using the tomb walls to understand the real-world turmoil cause by the death of the young king.

Cocoa shown to reduce blood pressure and arterial stiffness in real-life study – Cocoa flavanols only decrease blood pressure if it is elevated! I enjoy my morning dark chocolate (70+% cocoa) squares…a healthy way to begin the day!

A few more notes from November…

/

As November is ending - there are a few more items I want to post about….

My 90-year-old mother still enjoys making breakfast herself and my dad. I photographed one of her more elaborate breakfasts when I was visiting: microwaved sausage patty, sauteed peppers, mushrooms and onions + cheesy eggs from a skillet, and a freezer biscuit heated in a toaster oven. I’m glad that modern conveniences (microwave ovens, precooked sausage patties, frozen biscuits) make it easier for her to prepare meals.

A brown-headed cowbird visited out deck on a cold morning….alone, looking very round scrunched down in the cold. It stayed around for a bit. I wondered if it had become separated from a flock or was just enjoying the sunshine and relative safety of our deck.

The sun backlighting oak leaves gives their color more definition. This was a morning that the grass was frosty; by the time I took the picture the frost was beginning to melt but it still added a sparkle around the leaves.

My husband was out at a county park/astronomy site for the lunar eclipse in the early morning hours of the 19th. It was cold but he was prepared for that and stayed until the clouds obscured the moon about 5 AM. He took lots of photos!

Finally – I enjoy finding ways to reuse single use plastic. I’m not sure whether this was a bowl or a dome from a food purchase….but it makes an excellent stand for my laptop when I am using an external keyboard! It allows for plenty of air circulation around the laptop, raises it off the surface of the desk (in case I spill something), and the light shining through it is appealing too!

National Park Service Publications on Internet Archive

/

Last September - I browsed 18 publications from the National Park Service that have been scanned and are freely available on Internet Archive. They are all decades old….reflect history of the places. The oldest one is from 1917 (The National Parks Portfolio) which is clearly a snapshot from the early years of National Parks. I was particularly interested in the “Astronomy and astrophysics national historic landmark theme study” published in 1989 – the year my daughter was born and she has grown up to be an astrophysicist! The only park I visited before the publication was Yosemite; the publication is from 1990 and I visited in 1984. I’ve provided a sample image for each volume. Enjoy some armchair traveling with some browsing via Internet Archive…find some correlations in the publications and your own life.

Wind Cave, 1979

Agate Fossil Beds National Monument, Nebraska, 1980

Astronomy and astrophysics national historic landmark theme study, 1989

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.

Night Sky Celebrations Across the National Park System – We’re not doing this kind of traveling this summer….but maybe we’ll do several of these ‘star parties’ in summer 2022.

Tooth loss associated with increased cognitive impairment – Another reason to not neglect going to the dentist! It’s not just about preserving cognitive impairment either….quality of life is a big motivation as well.

Top 25 birds of the week: Seabirds – From around the world…a few I’ve seen in North America.

Mucus and mucins may become the medicine of the future – There is still a lot to learn about how this might work….but it appears that this is an opportunity to treat disease by enhancing the mechanisms already used by the body. Maybe one of the first uses will be for eye drops to treat eye infections rather than the antibiotics used today.

Protect Pollinators – reform pesticide regulations – Hopefully the action requested by these scientist from around the world will happen…our ecosystems are having enough challenge dealing with climate change. Many pollinator species won’t survive the continued threat of status quo pesticide use.

Keeping your composure: Creative Ways to Compose Your Photographs (part 1, part 2, part 3) – Always good to browse through these kinds of tutorials…pick up some new ideas, celebrate the things you are already doing.

What to do with food waste? – It doesn’t appear than there is any one strategy that will work broadly. I’m glad I have already dramatically reduced food waste and then have a large enough yard to have a compost bin.

Waterfalls of North Carolina – A few years ago, my husband and I made a waterfall themed trip to New York. It seems that North Carolina would be another state that has a lot of opportunities for waterfall photography. Maybe next spring?

Creativity Myths – A recent ‘letter’ on The Painter’s Keys website.  I enjoy the twice-weekly blurbs that appear in my inbox (free subscription) and often follow the ‘click here to read more’ link.

Exposure to light with less blue before sleep is better for energy metabolism – I already change the color balance on my PC screens to ‘nightlight’ between sundown and sunrise. Maybe we will do more eventually based on this and subsequent research. It is probably true that no one should be watching a television screen just before going to bed!

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.

Human egg cells are imperfect surprisingly often -- ScienceDaily – More than 7% of human oocytes contain at least one exchangeless chromosome pair…and the frequency is not affected by maternal age. Our species is hardwired to have significant numbers of miscarriages and babies with extra or missing chromosomes. The finding is interesting, but I immediately thought of some questions…has this changed over the past 100 years (i.e. have we changed our environment enough that we are impacting our reproductive success) and how does this frequency compare to other mammals?

Why our pursuit of happiness may be flawed - BBC Future – A thought provoking piece about how seeking ‘happiness’ often sets the stage for disappointment…rather than contentment.

Pollution from cooking remains in atmosphere for longer -- ScienceDaily – Eating deep-fat fried foods is not just unhealthy…the cooking of foods that way contributes to air pollution. In London, 10% of the PM2.5 particles are from deep fat frying….in Hong Kong 39%!

2nd Annual Threatened And Endangered Parks: Natural Darkness And Sounds – My husband and I are looking forward to more dark sky opportunities in national parks. So far – the ‘star parties’ we’ve been to have been at state parks and hosted by amateur astronomy clubs in the area. The dark sky venue requires a bit of infrastructure to support a field full of camping amateur astronomers with their telescopes (electricity for telescopes/computers and bath rooms with red tented windows).

Top 25 birds of the week: Colouration! - Wild Bird Revolution – Lots of color in this post to break up mostly brown and white winter color outside my window! 

U.S. Breaks Record for Billion-Dollar Climate Disasters in 2020 | Smart News | Smithsonian Magazine – Not a good record to be breaking…and they happened during a pandemic year too. There were 22 disasters that caused at least $1 billion in damages across America in 2020.

Q&A: Global Insect Declines Due to "Death by a Thousand Cuts" | The Scientist Magazine® - In every case researched….it’s not just one thing that caused the decline…it a cluster of primary factors (6 or more) and then other factors that are difficult to quantify.

Texas Wind Power Dominates Coal In Crossover Year – Hurray! Hopefully, the coal plants will begin to phase out in Texas and across the country as they become less and less competitive with renewable sources of power.

On the road to invisible solar panels: How tomorrow's windows will generate electricity -- ScienceDaily – I am always reluctant to consider replacement windows….but if they were cost effective solar panels…that would tip the decision toward ‘buy’!

Caligula's Gardens, Long Hidden Beneath Italian Apartment Building, to Go on View | Smart News | Smithsonian Magazine – A subterranean museum beneath the streets of Rome to open this spring.

Venturing Out and Weekly Gleanings

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

A Zentangle Prompt

20190401_140347.jpg

Inspiration for a pattern can come from our environment. Sometimes creating a pattern is relatively straightforward. The prompt for today is to create your own pattern based on the picture of tiles to the right. Hint: start with a grid of squares. Use your pattern in a tile. Other patterns in the tile are tangler’s choice (i.e. whatever you want).

Here are some tiles I made based on yesterdays prompt: Make a tile using the gingo pattern.

19 09 zent (17).jpg

It is one of my favorite patterns for mono-tangle tiles.

Venturing away from Home

I went to Howard Country Conservancy’s Mt Pleasant to record a Facebook Live Zentangle session. It was the first time I had driven my car in May! It was also my first volunteer gig since early March – and a good experience – but I realized how out of practice I have become with getting out and about. There was a ‘newness’ to my car even though I’ve had it for a few years. Mt Pleasant is a place I know very well but hadn’t been there since January; it felt unfamiliar.

I was glad the flip chart pad and gallery board were wrapped in plastic trash bags because it was raining heavily when I got there. It took two trips to get into the building and I was glad I had worn a windbreaker and waterproof boots.

The mask that I wore during set up did not stay in place as well as I wanted. I need more experience with securing it and being certain that I can breathe well enough through the layers of fabric. It’s a good ‘lesson learned’ before I venture out to try doing my own grocery shopping in June.

The materials I had prepared ahead of time worked well…minimizing the amount I had to create while I was talking.

The Facebook Live session lasted about 20 minutes and made a three-part tile using TIPPLE, CRESCENT MOON, and either MEER or POKEROOT. I missed not being able to create a mosaic of the student tiles at the end. Here are tiles I made with the patterns after the session.

I’m not sure how any of my volunteer gigs will be possible anytime soon but I’ll probably do some hiking at Mt. Pleasant…on a sunny day…another small ‘venturing away from home.’

Staunton River State Park – Chaos Star Party

/

Continuing the posts about our trek to the Chaos Star Party at Staunton River State Park….

The Virginia LOVE theme cares to the state parks. Staunton River’s included the date the park was established…1936.

2019 10 IMG_1949.jpg

There were various signs for the star party in the areas of the park dedicated to it. The field was full of tents and campers and trailers. We were in our roomy tent with a screened area for my husband’s electronics and chair….with the telescope just a few steps away. Some people probably were staying in the cabins and coming to the field with their telescope at night. We preferred a place to sleep near the telescope…makes it easier to lay down once the clouds roll in or the dew gets too heavy for observing. My husband had two clear-sky nights and had some observational successes (I slept relatively well through it all).

2019 10 IMG_1953.jpg

Someone did an excellent job with a pumpkin near the cantina.

We managed a short hike. We’d been hearing a lot of birds, but they must have been migrating through – stopping for the night on the water. They’d flown off by the time we were up and about. We did see a juvenile Red-headed Woodpecker making a hole in a dead branch (hanging upside down). I didn’t know what it was until after I got home and could check references. It was the drabbest woodpecker I’d ever seen! It will eventually have the distinctive red head.

2019 10 IMG_1959.jpg

The woodpecker was in some trees that were around the cabins at the park. Most of them were oaks and the acorns were plentiful….lots of food for the woodpecker and squirrels. There were some other nests around too but we weren’t seeing many other birds.

2019 10 IMG_1963.jpg

The sweet gums were full of color – reds and yellows. And the seeds…prickly.

2019 10 IMG_1967.jpg

A Great Blue Heron was one of the few birds we saw on the water. It was at the limit of the zoom on my camera.

2019 10 IMG_1971.jpg

I turned around on the beach and caught some motion in the leaves. A spider moving over the sand and onto a leaf where it was not as well camouflaged.

2019 10 IMG_1976.jpg
2019 10 IMG_2007.jpg

On the way back we noted the solar system model that has been set up starting with the sun (yellow orb) close to the observing field and extending along the road.

The morning we were getting ready to leave there was a sun dog. What a great serendipity for our last morning at the park!

3 Free eBooks – March 2019

/

In some months it’s hard to pick just three books to feature for the monthly eBooks post. March 2019 was one of those. I cheated a little and picked a periodical…with lots of issues available online…for the first one.

Baer, Casimir Hermann. Moderne Bauformen. Stuttgart: J. Hoffman. 1902-1923. Hathi Trust has volumes for each year here. A German periodical about architecture and interior design with many illustrations – some in color. It’s a slice of history of the period. Many of the interiors look modern…others dated. I realized again how appealing I find glass bricks, window seats, alcoves with benches and sometimes a table or a wall of windows and comfy chairs for reading, and curtains to divide a large room into segments. There were quite a few ideas I’ll use in Zentangle tiles as well.

Trouvelot, Etienne Leopold. The Trouvelot Astronomical Drawings. 1882. A slide show of 15 drawings is available from Internet Archive here. Trouvelot was well-known for his astronomical drawings made from observations at the Harvard College Observatory and the US Naval Observatory. Unfortunately, he also is the person that introduced the European Gypsy Moth into North America.

Day, Lewis Foreman. Nature in Ornament. New York: Charles Scribner’s sons. 1892. Available from Internet Archive here. Lots of ideas for Zentangle patterns in this book. I particularly liked the different stylized peacock feathers.

Gleanings of the Week Ending November 10, 2018

/

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.

Uncapped Wells Have Been Leaking Oil into the Gulf of Mexico for 14 Years - Yale E360 – Why can’t the oil companies do a better job of preventing leaks…or, at least, stopping leaks if they occur? Don’t they have the technology to address this issue?

With Shorter Winters, Plants Bloom Early and Die Young – National Geographic – Green springs…but the plants don’t sustain the green through the drier summers. Not good for our yards and our farms…and us.

Photo of the Week – October 19, 2018 – The Prairie Ecologist – Fluffy seeds from the prairie…including common milkweed,

Image of the Day: Clubbing | The Scientist Magazine® - Peacock Mantis Shrimp have a spring-like structure that enables them to beat the life out of their prey.

Beautifully Painted Shrine Emerges from the Ashes of Pompeii | Smart News | Smithsonian – Much of Pompeii that we know from tourist books was excavated before modern methods…and sometimes ‘restored’ in a way that we don’t know exactly what it looked like when originally uncovered. New excavation can provide clues about older excavations as well as the particulars of the newly uncovered walls.

Substantial changes in air pollution across China during 2015 to 2017 -- ScienceDaily – Particulates are down but ozone is up….so good and bad trends.

BBC - Future - The flu that transformed the 20th Century – The 1918 flu epidemic…100 years ago this year. There is still research on the virus and what happened…some surprises in the findings.

This Humongous Fungus Is as Massive as Three Blue Whales | Smart News | Smithsonian – 91 acres, 110 tons, and about 1,500 years old. And this is not the biggest one discovered…it was the first that was well documented.

Top 25 Wild Bird Photographs of the Week: Black plumage – National Geographic – I always like to include birds in my gleanings. I was surprised that there were no crows or ravens or starlings in this collection of birds with black plumage.

The Winners of the 2018 Astronomy Photographer of the Year Contest Are Out of This World – Three are some pictures from the 2017 solar eclipse in this collection.

NASA Visitor Center

/

Back in the early days of HoLLIE classes, we met in the parking lot of the NASA Goddard Visitor Center before going to our class; it was before it opened so I wanted to go back to see the visitor center exhibits. Last week – it happened. It was a cloudy morning with rain in the forecast. The center opens at 10 and I was there a few minutes afterward. There were only a couple of other early visitors.

I decided to do the outdoor Goddard Rocket Garden and Astobiology Walk first – since I wasn’t sure the weather would stay dry. Did you know that grooved pavement used for airport runways and other pavements was the result of a NASA Wallops Island study from the 1960s?

I took a lot of pictures of the astrobiology walk and made a slide show of them below (use the arrows to go through at your own speed).

My favorite displays were the two showing banded iron specimens.

Inside – there was a full-side mechanical prototype of the Lunar Reconnaissance Orbiter (LRO). We saw the operational control room for the mission during the HoLLIE class. It’s quite a thrill to know that the mission is ongoing – knowing that my daughter was an undergraduate at Cornell when LRO reached the moon and she helped with some of the initial image calibration since she had developed calibration skills in her part-time job calibrating images from the Mars rover.

There was also an exhibit of the new James Web Space Telescope – comparing its mirror with the one on the Hubble Space Telescope.

There was also a fun exhibit with two cameras and monitors. One was an infrared camera. It picked up the residual heat from ones feet on the carpet as one walked away from its field of view!

I bought a Cassini Grand Finale t-shirt for my daughter at the gift store; she used some data from Cassini for a couple of papers while she was an undergraduate. Hurray for good experiences!

Staunton River Star Party

Last Monday, we headed down to Virginia for the Staunton River Star Party. The event is held at the state park – a dark sky site. We waited until most of the morning rush hour was over since our route included the Washington DC beltway. There was still traffic, but it was moving at highway speeds even around the Mormon Temple. The rain from earlier in the morning had stopped and the clouds were beginning to break up.

We made a stop at the first rest area we came to on I95 south of the Washington Beltway – anticipating easy traffic for the rest of the way.

Lunch at a Chipotle was our mid-point break.

We arrived at the park about 3 and began setting up. I always enjoy the creative pumpkin carving that sits beside the door of the cantina. All the windows on the park buildings are covered with red cellophane and lights to mark paths are red as well.

I’ll be posting about the events of the week in the next few days….but I’m wrapping up this most with the road trip home last Friday.

We left the park about 10 and stopped at a fast food place for our first rest stop since we were not on an interstate yet and it was cool enough that my husband wanted something hot for brunch. We stopped for lunch at an Arby’s later then got on I95 shortly thereafter.

We stopped at the last rest stop on I95 before the Washington DC – obviously in Virginia.

But this rest stop has something I had not seen before – a toddler potty! I wonder if these are going to become more common as rest stops are remodeled.

We were glad to get home after crawling through the Friday afternoon traffic from 2-4. We waited until the next day to put the tent up in the backyard to dry out (we had to pack it up before the dew dried).

More to come about the Staunton River Star Party in upcoming posts.

Home Alone

/

I never lived alone so it is unusual to have some days to just be at home by myself – having no reason to be anywhere else. It happened this past weekend when my husband was away at the Black Forest Star Party at Cherry Springs State Park in Pennsylvania. I would not like it to happen frequently, but what a luxury for a few days! I got caught up on so much and enjoyed the quiet house.

And I still enjoyed some views of the star party my husband sent. They had relatively clear skies for 2 of the nights making it a worthwhile endeavor for the 500 or so people that were there camping on the field with their telescopes.
