6 chemical stories of colors through time – A little history of these colors….some very toxic!

Possible Neolithic Body Piercings Unearthed in Anatolia – Over 11,000 years old…found near ears and chins of human remains.

Under Threat in Their Native California, Giant Sequoias Are Thriving in Britain - First introduced to country estates in the 19th century, half a million sequoias now grow in Britain, compared to just 80,000 along the western flank of the Sierra Nevada in California, where they are increasingly imperiled by warming. Up to a fifth of all large giant sequoias in California died in wildfires in 2020 and 2021. The trees in Britain are still relatively young — sequoias can live for more than 3,000 years — and squat. In Britain’s cool, mild climate, sequoias are growing nearly as fast as in California.

Whales That Go Through Menopause Live Longer and May Help Care for Grandchildren - Female tooth whales that go through menopause (narwhals, killer whales, false killer whales, short-finned pilot whales and beluga whales) have longer lifespans than those that don’t, surviving decades past their reproductive prime!

A healthier diet is linked with a slower pace of aging, reduced dementia risk - We have some strong evidence that a healthy diet can protect against dementia…but the mechanism of this protection is not well understood. This study suggests that slower pace of aging mediates part of the relationship of healthy diet with reduced dementia risk, and therefore, monitoring pace of aging may inform dementia prevention. Additional observational studies need to be conducted to investigate direct associations of nutrients with brain aging.

The next pandemic? It’s already here for Earth’s wildlife – The pathogenic strain of avian influenza has killed millions of birds and unknown numbers of mammals. Between January 1, 2003 and December 21, 2023, 882 cases of human infection were reported from 23 countries, of which 461 (52%) were fatal. To prevent the worst outcomes for this virus, we must revisit its primary source: the incubator of intensive poultry farms.

Ultra-fast fashion is a disturbing trend undermining efforts to make the whole industry more sustainable - Ultra-fast fashion is marked by even faster production cycles, blink-and-you’ll-miss-it trends, and poor labor practices. Without change, the industry will account for 26% of the world’s carbon budget for limiting global warming to 2°C by 2050. Established brands such as Gap introduce 12,000 new items a year and H&M 25,000. But Shein leaves them in the dust, listing 1.3 million items in the same amount of time.

Seven ways to improve your sleep according to science – Science and historical perspective.

Warming Waters Bringing More Sharks to the Alabama Coast - Globally, warming waters are driving sharks to new areas where they were previously scarce. Great white sharks, tiger sharks, and bull sharks have all edged northward. From 2003 to 2020, the number of juvenile bull sharks swimming through Mobile Bay rose fivefold.

Incredible Winners of the 2024 British Wildlife Photography Awards – So many great images!

Gleanings of the Week Ending February 10, 2024

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.

Sleep tight: A curious history of beds through the centuries – From 4,500 year old ‘beds’ at Skara Brae (Scottish island of Orkney…rectangular enclosures, around the length of a human…made from slabs of cold, hard stone…with tall headboards and raised sides) to Durrington Walls near Stonehenge (spectral outlines of long-vanished wooden bed boxes, where the builders of that monument may have once slept) to a clay figurine of a woman slumbering peacefully on her side, one hand under her head, on a simple raised platform to the gilded wooden bed in King Tut’s tomb (including a rigid, raised headrest rather than a soft pillow) to mats of dried leaves or animal skins to box beds to the ‘tick mattress’…hints of beds of the past.

Peru’s High-Altitude Hunter-Gatherers Ate Mostly Plants – Wild potatoes and the root vegetables made up 80% of their diet.

Rethinking Monarchs: Does the Beloved Butterfly Need Our Help? - The Xerces Society has published a joint statement signed by 10 top monarch biologists warning against the captive rearing and releasing of monarchs by backyard and commercial breeders. Such activities, they wrote, “promote crowding and disease spread.” The monarch is not in peril since the winter population in Mexico has shown no continued decline for the past 10 years. --- But there are some that still argue for continued ‘help.’

Deceptively Beautiful Invasive Plants – Avoid Lessor Celadine, Mimosa Tree, English Ivy…..Today, we have the opportunity to make gardening choices that benefit both the aesthetics of our gardens and local wildlife by removing invasive species and replacing them with beautiful and wildlife-friendly native alternatives. 

See the World Through the Eyes of Animals with These Stunning New Videos - To “see through” animal eyes, the team uses two cameras—one sensitive to ultraviolet light and one sensitive to visible light. Together, they capture light in four distinct wavelengths: blue, green, red and ultraviolet.

New genetic variants found in large Chinese mother–baby study - Mothers with higher blood pressure give birth to lighter and shorter babies than do mothers with lower blood pressure. This was just one of a multitude of links between maternal health and fetal development observed in a large genetic analysis of Chinese parents and their babies, which included some unexpected results. The researchers sequenced genetic data from blood samples taken from the parents and umbilical-cord blood of the infants and collected physical information about the mothers and their babies, including height and weight. The researchers identified discrepancies in the effect of some genetic variants on the same trait between mothers and their babies. For example, some variants were associated with altered cholesterol levels in infants but not in their mothers, and vice versa.

Preserving History at Bandelier National Monument – Two videos that show recreations of what the structures looked like in use based on archeological findings.

The 4-Second Nap: Unusual Sleep Habits of Animals - The killer whale, which can go a month or more without sleeping. Or the chinstrap penguin, which researchers recently discovered sleeps in four-second microbursts. Compare that to the koala, which conks out for most of the day.  When dolphins are sleeping with one hemisphere, one eye closes and one remains open. They sometimes rest motionless near the surface of the water or swim slowly, still able to breathe when needed. African elephants sleep for the least amount of time recorded of any land mammal.  The domestic horse sleeps just under three hours on average each day, and the domestic pony sleeps about three hours and 20 minutes. 

How a walk in nature restores attention - The study, conducted in 2022 between April and October, analyzed EEG data recorded on each of 92 participants immediately before and after they undertook a 40-minute walk. Half walked through Red Butte, the arboretum in the foothills just east of the University of Utah, and half through the nearby asphalt-laden medical campus. The participants that had walked in nature showed an improvement in their executive attention, whereas the urban walkers did not.

Climate change is causing a pothole plague. Are robots and self-healing pavement the solution? - In the United States, about 44 million drivers reported damage to their vehicles from potholes in 2022, which was a massive 57% increase over 2021, according to AAA. New developments offer hope for addressing potholes more effectively amid climate change, and are attracting investors….but innovations take time to be implemented.

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 autoimmune diseases be cured? - After decades of frustration and failed attempts, scientists might finally be on the cusp of developing therapies to restore immune ‘tolerance’ in conditions such as diabetes, lupus and multiple sclerosis.

Good and bad news for people with low back pain - The good news is that most episodes of back pain recover, and this is the case even if you have already had back pain for a couple of months. The bad news is that once you have had back pain for more than a few months, the chance of recovery is much lower. This reminds us that although nearly everyone experiences back pain, some people do better than others, but we don't completely understand why.

Why diphtheria is making a comeback - While this present surge of diphtheria cases is indeed unprecedented for West Africa, it is really a symptom of larger issues in global health, including insufficient infectious disease surveillance, poor vaccination rates and scarcity of public health resources.

The Prairie Ecologists Photos of the Week – January 22 2024 – Photographs from out in the cold.

The chemistry of meat alternatives – It’s complicated…..in the end are meat alternative ultra-processed food?

The strange reasons medieval people slept in cupboards – I can see how they might have been warmer….but also rather claustrophobic. And wouldn’t they be hard to keep clean?

In the time of the copper kings - Some 3,500 years ago, prosperous merchants on Cyprus controlled the world’s most valuable commodity. Beginning in the third millennium B.C., and especially during the second millennium B.C., copper was king and could make those who possessed it extremely wealthy and powerful. There was enough copper and tin on board the Uluburun ship (wrecked off the coast of Turkey) to produce 11 tons of bronze, which experts estimate could have been turned into 33,000 swords. Researchers have analyzed the Uluburun wreck’s copper and found that it all came from Cyprus. There is evidence of the surprisingly diverse nature of the community thriving there and that those Cypriots who controlled the production and distribution of copper, such as the shipment found off Uluburun, could become exceptionally rich.

Cicadas Are Coming: Rare ‘Dual Emergence’ Could Bring One Trillion of the Bugs This Year – We don’t live in the overlap area…but where we live in Missouri will see Brood XIX this summer….a great opportunity for cicada photography!

Incredible Winners of the Close-Up Photographer of the Year Contest – So many beautiful images. My favorite is ‘Spirit of Yucatan’ (drifting stems of lily pads in a Mexican freshwater cenote…the sky above).

Deepwater Horizon oil spill study could lead to overhaul of cleanup processes worldwide – Chemical oil dispersants combined with sunlight…made oil more toxic. Observations from after Deepwater Horizon, and being confirmed experimentally, to improve responses to oil spills.

Glad to be Home

As I write this, I have been home again for a week after being away almost 7 weeks. It had taken this long to get settle back into an at-home routine….to relax enough to feel truly rested! At first, I felt so exhausted that I took naps – which didn’t seem to help. It took me 5 days to fully empty my car. I needed the alone time after being so engaged with people all the time; I didn’t want to talk on the phone at all…had to force myself to check my text message. My emotions were still volatile, and I consciously started trying to unwind. Cutting back on caffeine, getting more exercise and quick neighborhood hikes (even though it was cold outside) finally worked.

It’s such a joy to just be home. I’ve enjoyed returning to spending more time just being in my house…cooking, reading, writing, making Zentangle tiles, and planning one or two vacation travels for the next 6 months. I pampered myself included burning a scented candle I’ve had for years, a facial (using supplies from a Christmas gift), hot apple cider rooibos tea, big red peppermint stick, and pumpkin oatmeal cookie bars.

As the days passed, I fell myself recovering…although there are some aspects of the past 7 weeks that might be a permanent change. I’ve learned more about how I deal with stress --- holding off its effects until the crisis is ‘over’ --- and then requiring time to recover. It is a strategy and provided enough resilience, but I might need to bolster by stress reduction techniques in preparation for the next crisis; more self-care during a crisis might make recovery easier (or unneeded).

I’ll be taking off for another trip to Carrollton TX soon, but the trip will be only 6 days this time! Much easier!

Ten Little Celebrations – December 2023

December has been one of the most unusual (and stressful) of my life. Along with all the upheaval – there were still little celebrations to notice and savor.

Completion of a construction project. Big machinery digging in the street/sidewalk, the alleyway, and backyard of my parents house. The city was replacing an old sewer pipe. It was interesting to watch…although there were a few anxious moments too. We all celebrated when they finished within the 3 days they’d estimated for the project!

A warm day to mow the leaves. The leaves didn’t really begin to fall in Carrollton TX until December. We celebrated a warm day to mow them into the yard.

Crystalized ginger, big peppermint sticks. I savored special foods from the past that I haven’t eaten as much in recent years. I bought the crystalized ginger and a sister provided 6 of the big barber pole peppermint sticks. I started the celebration of my birthday early!

Red velvet cake. When I was growing up, my usual birthday cake was red velvet cake – made by my mother. This year one of sisters and her husband discovered a diner that had an excellent version of the cake – and bought me two pieces – which I enjoyed 2 days in a row prior to the actual birthday!

A break. My other sister came to make lunch for my parents and I took a break away from my parents’ house. I went to a small café for brunch and they had a special: birthday pancakes! I opted to get that special (another early birthday celebration) and thoroughly enjoyed it. Then I walked (and took pictures of birds) around Josey Ranch.

December celebrations. My birthday is just one of the normal December celebrations in my family. There is also my parents’ anniversary (their 71st) and Christmas! It’s always a hectic month…full of family visits.

Good sleep. I usually sleep well but it has not been as consistent this month….so I celebrated a particularly good night!

Fall foliage of crape myrtles. I’d never noticed crape mytles in the fall before. At my parents the conditions must have been just right for them to turn from green and hold their leaves this year. I celebrated how great they looked with the leaves and seed pods.  

Finding assisted living. Change is hard. We had moments of discovery and panic…celebrated finding an assisted living group home for my parents and then realizing that the details required another burst of energy. As I write this we are all celebrating how much we have accomplished with our combined efforts.

Daughter arriving. My daughter came for my birthday and the anniversary. She took me out for Ethiopian food to celebrate my birthday!

December 2023….what a cresendo for the year!

Ten Little Celebrations – March 2023

March has been a bit different than I expected…a lot more very cold starts to the days which have made it harder for the spring bulbs I planted last fall. Still – there was plenty to celebrate.

Clean car. The dust (and maybe salt) is rinsed off the car. I celebrated the days of driving a clean car…until I drove around the gravel road that is the wildlife loop at Hagerman National Wildlife Refuge! The door and hatch seals keep the dust from getting into the car but the spaces before the seals are covered and the car wash does not reach it!

Banana bread (that included the peels). I will never make banana bread without the peels again. Yes – organic bananas are a bit more expensive…but the bread is so good….well worth it.

Plans for our back yard. So many ideas…and enough time to make them happen! The evidence of the work I did last fall (planting bulbs) is giving me confidence that I can do more. Maybe I’ll even become a gardener.

Frosty forsythia. The cold mornings were problematic for some of early blooming flowers, bushes, and trees. I celebrated that I captured the beauty of frost on the forsythia flowers.

Pumpkin soup. I was surprised that I had more than 4 cans of pumpkin in my pantry….not sure how it happened. I opted to make soup with one of them. Tastey…colorful…a celebration with winter fare on a cold March day.

Staying standard time for sleep. I like for the sun to be coming up when I go down to my office and didn’t like the beginning of daylight savings time because it was suddenly dark again at that time….so this year I opted to not change my sleep schedule from standard time. I celebrate the light every morning with my first cup of tea.

Walking around the neighborhood ponds 2 days in a row. It seems like the month has had a lot of cold or wet days, so I celebrated when there were 2 warmer sunny days to make pleasant walks around our neighborhood ponds.

Two mockingbirds. This time of year, I look for pairs of birds around where I live. This year, I celebrated two mockingbirds close to my house. I hope they nest somewhere nearby. Last year we had a blue jay nest in one of our front yard red maples and barn swallows nested under our deck. There must be nests of mourning doves and finches nesting nearby too because we have so many of them.

New low weight for the year. Celebrating another month of taking off some weight. This needs to continue for as long as it takes to reach my goal (and then some to sustain it)!

Birdsong in the morning. The birds chorus in the morning and I celebrate the start of the day with them. I try to identify the birds I am hearing…a lot of robins usually but others join too.

Daylight Savings Time

Getting up in the dark is no fun and the time of year I notice it the most is at the beginning of Daylight Savings Time. Just when I am enjoying the sunrises when I get to my office on standard time, the change happens and it’s dark again. So – this year I am trying something new: I am going to get up an hour later (and go to bed an hour later); it has the effect of staying on standard time for my sleep schedule!

Why didn’t I think of this before? During my career it would not have worked. I got too much done during the early mornings before everyone else arrived and the traffic would have been horrendous an hour later than my usual. When my daughter was young, my husband took her to daycare, and I picked her up early since my workday (usually) ended earlier; shortening her time away from us was our goal. Later, when she was in high school, her day started as early as mine did.

But – I could have easily done this ‘changing of the morning wakeup alarm’ during the past decade. There are very few instances that I need to be anywhere before 8 or 9.

I guess this means that if the country stays on the same time year-round my preference is for standard time since I like it to be light in the morning! If the country decides on staying on Daylight Savings – I’ll simply keep my sleep time ‘standard.’

I am celebrating sunrises with this little collection of images over the past year.

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.

Circadian rhythm disruption found to be common among mental health disorders – A lot of research challenges…therapeutic potential.

Striking Winners of the 2022 Black and White Photo Awards – Perhaps I’ll try a B/W photography project…

Global Survey: Climate Change is the Top Threat – Finally….more people are beginning in realize the peril of doing nothing.

Industrial Revolution Reversed 7,000-Year Cooling Trend in Siberia, Bringing Temperatures to Unprecedented Highs – Another aspect of climate change…that threatens to unleash more greenhouse gases…spurring further warming.

Wooden canoe burial discovered in Northern Patagonia – From 850-1,000 years ago….a woman buried in a ceremonial canoe made from a Chilean cedar.

Photographer gets rare glimpse of British Columbia’s Spirit Bear – The black bears with a mutation that blocks the production of melanin…and makes them less visible to salmon (i.e. they catch the fish more effectively than the bears that are black!).

Feeling anxious or blue? Ultra-processed foods may be to blame – A study with over 10 thousand participants. Learn more about the NOVA food classification system used in the study here.

In the field with wolverines – Interesting animals that live in northern areas around the world…only about 300 of them in the lower 48 of the US (in Idaho, Montana, Washington, and Wyoming).

First sighting of massive Atlas moth confirmed (in Seattle) – The Atlas moth is from tropical Asia. The conservatory-based butterfly exhibit I volunteered with for several years (in Maryland) included them occasionally; they were contained in the facility following the permit requirements. Hopefully the one in Seattle didn’t find a mate. Their caterpillars would feast on leaves of apple and cherry trees.

These Early Entries From the 2022 Comedy Wildlife Photo Awards Are a Hoot – Ending the gleanings list with some fun images.

Gleanings of the Week Ending June 4, 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.

Under Water and Under Pressure – 100 national parks are coastal…and are already taking action to mitigate sea level rise.

Where do ‘Hawaiian box jellies’ come from? – Evidently the box jellies appear close to shore like clockwork 8-10 days after full moon. This research reveal that the jellies are spawning during that time…and where they are when they not close to shore. This is important for providing better information to ocean swimmers and beach goers…trying to avoid stings. Another benefit…learning to keep the food web balanced to control box jelly numbers in Hawaii and other tropical localities.

Stirring up a mid-Atlantic bloom – Lots of nutrients flowing into the water from the coastal watersheds during spring rainstorms.

Vancouver requires gas stations & parking lots without EV chargers to pay $10,000 per year – Interesting idea…hope it increases the number of chargers and the trend to EVs!

Photography In The National Parks: More Favorite Places For Photography - We’re not going to be traveling to any of the western parks near term….so I enjoyed them through these photographs: Crater Lake, Redwood, Yosemite, Great Basin, and Lewis and Clark (Washington state portion).

Maya tooth treatments may have prevented infection – In the Mayan world - holes were drilled to attach stones to teeth; an analysis of the sealant used for 8 teeth from across the Maya empire (AD 200-900) revealed that most sealants included ingredients from pine trees that have been shown to fight the bacteria that cause tooth decay.

Top 25 birds of the week: Forest Birds – I always like bird pictures….

Scientists recreate Cleopatra’s favorite perfume – Recreating Mendesian perfume…the result so far has been a strong, spicy, faintly musty scent that tended to linger longer than modern fragrances…with ingredients like desert date oil, myrrh, cinnamon, and pine resin.

Grand Canyon of Texas – I remember (tent) camping in Palo Duro Canyon in the 1970s on the way to Colorado…being very hot and worried that our tent was too close to a red ant bed! At the time, I didn’t realize that it is the second largest canyon in the US (behind Arizona’s Grand Canyon).

Why humans get less sleep than other primates – A different type of sleep research…teasing out the differences in sleep of humans and other primates….and between non-industrial human populations and industrial human populations. It turns out that in the human populations…the hours of sleep are about the same but the perception of getting enough sleep is higher in the non-industrial populations than the industrial ones!

Gleanings of the Week Ending January 22, 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.

The Roots of Violence – Reexamining bones excavated in the 1960s with new 3D imaging techniques….defining the violence of their lives and deaths shown in the bones. There is a history of archeological thinking here too. For a long time, evidently there was a presumption that prehistory was a less violent time…but the evidence is mounting that it was not.

Reducing air pollution: policies that pay off – An analysis done in Europe of the economic benefit of measures to reduce fine particle air pollution from wood heating and transport. It seems that similar type analysis could happen in other places in the world with some variation to tailor the reductions to have the biggest impact.

30 Incredible Winning Photos From the 2021 Nature Photographer of the Year Contest – Some eye-candy. My favorite is the caterpillar ‘walking among fennels’ – a similar scene happened at our CSA the first summer of the pandemic.

Assessing the U.S. Climate in 2021 – There were 20 separate billion-dollar weather and climate disasters that impacted the US in 2021.

Savanna Fire Management Can Fund Africa’s Protected Areas – Another article about the new economics we will need to understand to address climate change.

The forgotten medieval habit of 'two sleeps' – Maybe one long period of sleep is ‘modern’….that humans slept in two phases prior to the industrial revolution. One of my grandmothers developed a ‘two sleeps’ pattern late in her life when she was living alone….and I am beginning to wonder if I will.

The Horned Helmets Falsely Attributed to Vikings Are Actually Nearly 3,000 Years Old – Another look at artifacts…and better dating…and the history derived/assumed previously is changed.

Top 25 birds of the week: bird coloration! – This time of year…a little color from birds is a welcome sight. I’m noticing the ones in my neighborhood: Northern Cardinal, House finches, and red-bellied woodpeckers.

Across the Boreal Forest, Scientists Are Tracking Warming’s Toll – The northern forests becoming carbon emitters….. peatlands are drying out, and hotter, drier conditions are leading to a steady increase in wildfires — all of it accelerating permafrost thaw.

The Legacy Of "Pele's Grandson," Alex Lancaster – Some history of volcano observation on the big island.

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.

The great experiment to put a price on nature – Whether it’s toting up ecosystem services or simply realizing that Mother Earth is our one and only…we should all realize that we need to start taking care of ‘nature’ a lot better than we have in the past.

Microplastics May Be Impacting the Climate, Study Finds – A starting point for combining climate science and microplastic science into a model….still a lot if refinement/additions. We already know that the microplastics in our atmosphere are increasing so whatever impact they have it will likely be increasing during the time the model is being refined.

Ancient Stone Ram Heads Unearthed on Egypt’s ‘Avenue of the Sphinxes’ – New finds…and part of an advertisement for some restored places reopening in early November. Are tourists ready to travel again to places like Egypt?

Spending time in nature promotes early childhood development – A study from metro Vancouver of 27,372 children from birth to age 5… that pushes us to get serious about making sure spaces for children include a lot green space…that includes day care and preschools and K within the age range for this study. And while we are doing that – let’s think about how important green space is to everyone else too.

Meet the muskrat: push-up champion of cattail marshes – This article made me wonder if muskrats eat phragmites – and a plant that is taking over marshes. I found an article that says they do…at least in some situations.

Changing ocean currents are driving extreme winter weather – Looking at the impact of the slowing Atlantic Meridional Overturning Circulation (AMOC) and extreme cold weather (like in Texas last February) using a high-resolution global climate model. They’ve only done the simplest model (turning off the AMOC) so far…but plan to refine it to address the more complex reality.

Finding Fall Colors At Bandelier National Monument – I hope everyone found someplace to enjoy fall colors these past few weeks. My main opportunities were in my own backyard and as I was driving down the highway between Maryland and Texas!

Cheers! Wine’s red grape pulp offers nutritional bounty – Not compost or fodder...getting more than wine from vineyards!

Hit the sleep ‘sweet spot’ to keep brain sharp – Evidently 5.5-7.5 hours of self-reported sleep is about right.

2021 EPSON International Pano Awards Celebrate the Creativity of Panoramic Photography – Enjoy some eye candy as the last of this week’s gleanings!

Gleanings of the Week Ending July 24, 2021

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.

Massive Arecibo Telescope Collapses in Puerto Rico | Smart News | Smithsonian Magazine – Very sad. It was already being decommissioned which was wrenching….but then the collapse meant that even the instruments that might have been usable elsewhere were destroyed. My husband spent some time at Arecibo during his graduate school studies in the 1970s.

What do slight arm movements reveal about our breathing and health? -- ScienceDaily – Evidently it works best during sleep when there is not a lot of other movement other than breathing!

Hegra, an Ancient City in Saudi Arabia Untouched for Millennia, Makes Its Public Debut | Travel | Smithsonian Magazine – Undisturbed for 2,000 years…once an international trade hub although most of the surviving structures are tombs…a few hundred miles to the south of Petra

Proterra Sells Its 1,000th Electric Bus and New Electric School Buses In Virginia & Massachusetts – Electric buses are very appealing…I’ve always hated the sooty exhaust from diesel buses. Buses operate in situations where many people (and children) are in close proximity, so removing buses as a source of city and school pollution would be a good step forward.

Glyphosate may affect human gut microbiota -- ScienceDaily – A bioinformatics tool to predict if a microbe is sensitive to glyphosate – in the soil…in the digestive system of animals. The compound, widely used as a herbicide, biochemically targets plants but the same pathway is also in bacteria.

Opinion: The Biological Function of Dreams | The Scientist Magazine® - Learning more about sleep…and REM sleep in particular.

The mystery of Siberia’s exploding craters - BBC Future – Gas emission craters. Studies have revealed a 3-5 year life cycle: a mound forms…rising several meters, the gas underneath explodes. They tend to form in areas where there is a thick layer of ice over permafrost…with some areas of unfrozen ground surrounded by permafrost…and very deep deposits of gas and oil. The big challenge has been to identify the source of the gas that builds up – because after the explosion it is already gone.

Forest fires, cars, power plants join list of risk factors for Alzheimer's disease: Airborne pollution implicated in amyloid plaques, UCSF-led study shows -- ScienceDaily and Air pollution spikes linked to lower test scores for Salt Lake County third graders -- ScienceDaily – Studies that show the impact of air pollution on humans….other reasons to step up the pace of the shift away from fossil fuels. Thinking positively – actions to address climate change tend to improve air quality.

Mistletoe: A Natural and Human History – A plant associated with the season! And there are other species of mistletoe from around the world.

Top 25 birds of the week: December 2020! - Wild Bird Revolution – Beautiful birds….at the end of the gleanings list for this week.

Zentangle® – September 2020

Just as in prior months of the pandemic…I had a lot of Zentangle® tiles to choose from – getting to the 30 to showcase in this post. There are 16 square tiles in various colors of card stock and lightweight cardboard.  Note that all the tiles this month are made with dark ink (usually black) and I will make a second pass on the tiles to color them later; I have discovered that I enjoy coloring tiles as the wind down to bedtime.

The rectangular tiles are all made on lightweight cardboard from between layers of cans in cat food boxes. The short side is 3.5 inches and the longer side is the width of the cat food box.

I can’t resist the gingo pattern and have started making ones with more ‘leaves’…trying to always keep to an odd number!

I’ll do a post later this month with tiles that I’ve colored…trying to pick the top 10 is going to be more challenging than the selection for this post!

Gleanings of the Week Ending September 12, 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.

Top 25 birds of the week: September 2020 - Wild Bird Revolution – Starting out this list with bird pictures!

The wind turbines standing up to the world’s worst storms - BBC Future – Designing turbines that can withstand typhoons in the Philippines and Japan….at the same time climate change is making the storms stronger. We are going to need more of this kind of engineering.

Photography in The National Parks: Capturing Sunrise, Sunset, And the Milky Way At Mount Rainier’s Sunrise Area – Good views of Mount Rainier…and a photography tutorial…with ‘how to’ during the pandemic.

Home Valuation Needs to Consider the Risk of Climate Change - News | Planetizen – The piece is focused on sea-level rise but there are other climate change factors that might also need to be considered: increasing drought (i.e. some places that won’t have enough water to support the population living there) and – perhaps related – extreme heat/fire risk. Our government should not be willing to buy increasingly risky mortgages through Fannie Mae and Freddie Mac.

Cassowary Quest: A Tale of Danger and Defecation – Learn a bit about the cassowary – great picture and video too.

American Academy of Sleep Medicine calls for elimination of daylight-saving time -- ScienceDaily – I hope the drive to not switch times begins to gain momentum. It’s annoying – and not healthy for us either.

Dragonflies the Star of Photography Book About Their Lifecycle – We didn’t get to Kenilworth Aquatic Gardens this year to photograph dragonflies (along with the lotuses). These pictures are awesome….and encourage me to think about spending more time near ponds next summer.

The rare plants that ‘bleed’ nickel - BBC Future – Phyto-mining may be an alternative to using heavy machinery, destroying an ecosystem, and producing toxic waste. Hopefully, the work being done now will quickly become the dominate way to mine nickel.

A Field Guide to Finding Cool Moths – Mothing is (not yet) as popular as birding. The techniques discussed in this article are a good start. I’m going to try leaving the porchlight on tonight – checking around it before I go to bed and then again when I first get up (when it’s still dark outside). I’ve seen and photographed several of the moths mentioned in the article:

Hummingbird moth (Maryland in 2016)

20180806_093109.jpg

Ailanthus webworm moth (Maryland in 2018)

20190603_100414.jpg

Luna moth (Missouri in 2019)

Polyphemus moth (Maryland in 2019)

20190826_085319.jpg

Understanding how birds respond to extreme weather can inform conservation efforts -- ScienceDaily – An example of how scientists use the data submitted by a large number of people into eBird to answer questions re the impact of climate change and the resilience of birds (or lack of resilience).  

Unique Activities for Yesterday:

Prius Prime maintenance. The miles put on the car since the last service were minimal, but it was time for the maintenance. Everyone at the dealership was wearing masks but there didn’t seem to be any hand sanitizer stations (I was glad I had brought my own). I brought disinfectant wipes for the inside car surfaces when I picked up the car and then drove away with the windows open to clear out the air in the car….continued to wear my mask for most of the drive home.  

I’ve about used up the tank of gas I bought 9 months ago so I’ll fill it up and start plugging it in again to do all my errands with it as an EV. I hope there is a vaccine available by the end of the year --- and I’ll be out and about a lot more.

Mini-clover update. We’ve had gentle rain for the past few days and temperatures in the low 70s into the 80s. The clover is a cloud of tiny of green leaves on the surface of the bare spots in our yard. This is evidently good clover growing weather!

Monarch Caterpillar update. I only found one caterpillar this morning and it hasn’t moved much since I saw it yesterday. It’s large…hope it is about ready to make a chrysalis.

Gleanings for Week Ending June 27, 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.

What if all viruses disappeared? - BBC Future – We are more aware of pathogenic viruses….but there are a lot more that are not pathogenic to humans….and are often beneficial (directly and indirectly).

Scythian Warrior's Genome Analyzed - Archaeology Magazine – Surprise! Discovered in 1988 and assumed to be a young warrior based on the weapons in the grave. DNA revealed it was a girl and was younger than 14 years old.

90 Percent of U.S. Could Be Powered by Renewables by 2035 - Yale E360 – Technically feasible…but do we have the determination as a country to do what we need to do for future generations?

Repetitive negative thinking linked to dementia risk -- ScienceDaily – But can training/therapy to reduce negative thinking reduce the risk? Whether it does or doesn’t – it seems that people who perceive the positives in their lives are more satisfied/happy….so teaching strategies to enhance that kind of thinking is probably worth it.

How Iceland is undoing carbon emissions for good - BBC Future – Examples of how Iceland is pushing the technical envelope for carbon capture even in heavy industry.

What Makes Some People More Resilient Than Others - The New York Times – Tools most common in resilient people: realistic optimism, a moral compass, religious or spiritual beliefs, cognitive and emotional flexibility, social connectedness.

Memory consolidation during REM sleep: Researchers identify neurons responsible for memory consolidation during REM sleep -- ScienceDaily – I remember the babies I’ve known well having frequent REM sleep….they are doing a lot of memory consolidation!

Top 25 birds of the week: Camouflage – They are easy to spot in these zoomed pictures….in the field, their camouflage is highly effective.

Urine test reveals quality of your diet -- and whether it's the best fit for your body – Interesting work. Maybe in the future we’ll get feedback from the toilet about the ‘health’ of our diet as easily as we get feedback about heart rate and sleep quality from wearable devises now.

The Winnowing of the Wilson’s Snipe – A bird that could fit in the camouflage group…but this bird is special – it makes sound with specialized tail feathers!

Unique activities for yesterday:

Three kinds of day lilies. I have three different kinds of day lilies blooming right now. I love having the flowers in my office and something new opening every day!

Ice maker repair. My husband ordered a replacement part for our ice maker once we started having water overflowing the unit and accumulating in the freezer. He’d done some research online and it seemed likely that the new part would fix the problem. It came and after a few days of the box sitting around to decontaminate, we pulled out the refrigerator to install it (using the opportunity to clean the floor too). This is the type of thing we would have called for repair service pre-pandemic. There are areas where we’ve become a lot more resourceful in recent months and I wonder if we’ll continue that trend post-pandemic.

Gleanings, MAELSTROM prompt, and a Phoebe

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

Gleanings from the Past Week

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.

The world’s most nutritious foods - BBC Future – The one on the list that surprised me was ‘pork fat.’

New Thoughts on Corn Cultivation at Cahokia - Archaeology Magazine – Evidently maize arrived between AD 900 and 1000…about 1,000 years later than previously thought. I remember visiting Cahokia in 2010 about this time….a road trip from Ithaca NY to Flagstaff AZ with my daughter for her summer of undergraduate research.

Old Wisteria Tree in Japan Is the Most Beautiful in the World – I missed the wisteria blooming at Brookside Gardens this year. This 150 year old tree in this post is huge in comparison.

How the news changes the way we think and behave - BBC Future – I find that I feel better when I don’t check the news as often…once or twice a day is often enough unless there is something happening that impacts what I am doing (like very bad weather coming). I want to stay informed but don’t need stories repeated again and again…one time is generally enough and there are very few that I need to know as they are developing.

Top 25 birds of the week: #May 2020 - Wild Bird Revolution – A little feathery color….

Waves of Fluid Bathe the Sleeping Brain, Perhaps to Clear Waste | The Scientist Magazine®  - Still a lot to learn about the brain. I found myself wondering of poor sleep is the cause or effect of some disorders.

An Intimate Look at Italy’s Saffron Harvest - The New York Times – Color and flavor – and labor intensive.

Saber-tooth surprise: Fossils redraw picture of the fearsome big cat – The big cat was a forest/ambush hunter rather than one that hunted in more open environments.

Welcome Back! | The Prairie Ecologist – Noticing the firsts of spring….a bird returned…insects emerging (or sometimes returning), plants beginning to grow….lots to take in.

Medieval Arrows Inflicted Injuries That Mirror Damage Caused by Modern Bullets | Smart News | Smithsonian Magazine – The English longbow. The best ones were made from yew and measured 6 feet long. Drawing the weapon required 150-180 pounds of force. They shot arrows to 1,000 feet. At the Battle of Crecy in 1346, historians estimate that the English archers shot as many as 35,000 arrows per minute….were victorious even though they were outnumber by 2 to 1.

A Zentangle Prompt

Experiment with the MAELSTROM pattern. This is a grid pattern and is an opportunity to play with different orientations of a simple basic design made in each small square.  I always like to reuse materials I have around the house and an old calendar is great for these patterns. My calendar has large enough blocks for each day that I divide each into 4 x 4 grids and then cover the whole page (except for the small blocks that have a number in them) – in this case with MAELSTROM variations. I’ll share the results with you tomorrow.

img843.jpg

Here is a tile I made yesterday based on the prompt: Make a tile with TRIPOLI as the central tangle.

Unique activities for yesterday:

Phoebe in the morning. I hear a phoebe almost every morning but usually don’t get a photograph. Yesterday I did…while it was proclaiming its name.

IMG_9976.jpg

Small chipping sparrow. I’ve noticed a chipping sparrow that looks smaller than the others coming to the feeder the past couple of days. I finally got a picture of it with another chipper on the other side of the feeder. Doesn’t the one on the right look smaller? Maybe it is just the way the bird is oriented/holding itself.

Filling a Day of Social Distance – 3/19/2020

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

Here are the unique activities for yesterday…a cloudy day that started out very wet:

  • Trying another grocery store – first thing in the morning again. We found meat! It wasn’t our usual organic…but we bought it anyway. We also found some spray Lysol but not disinfecting counter cleaner…we are using our backup plan which will involve gloves, open windows and fans on (fortunately we are going to have some warm days). We got the medicines we would need if we got sick and my husband’s favorite protein shakes. Still no toilet paper or cat food. We ordered the cat food online when we got home.

20200319_103045.jpg

Reducing toilet paper consumption dramatically. We have water in spray bottles beside our toilets now. We haven’t eliminated toilet paper entirely…but we are building up our skills with the water. It should enable us to manage with the toilet paper we have in the house for a few weeks even though we have not been able to find any in stores recently. Maybe this strategy will last beyond this crisis….it would make sewage treatment easier and reduce the number of trees felled to make toilet paper.

  • Noticing that I am sleeping as well as ever (according to my Fitbit…and not feeling tired). It’s an indicator that I am still handling the stress of the pandemic and changing habits very well. Another indicator from my Fitbit: my resting heart rate has stayed below 65 (normal for me) the whole time.

  • Cooking sweet potato hash browns. We cook and eat at home most of the time. But I have more time now, so I am beginning to experiment. I got the idea for hash browns from my husband requesting the frozen variety of hash browns when I went to the grocery store…but I changed the potato from russet/white to sweet for my dinner! I scrubbed the sweet potato and cut off the ends…chunked it so it would fit in the food processor with the shredder attachment…cooked them in a little olive oil seasoned with onion flakes and no-salt seasoning. It made a good meal with scrambled eggs…pretty orange and yellow colors on the plate.

  • Filling the bird feeder. We let the bird feeder hang empty for the past week to discourage a hawk that has become too interested in our backyard. Now we get to observe how long it takes for the little birds to find the seed again. Are the juncos still around?

  • Unpacking the bin prepped for a Zentangle® class. My plan for 3/19 from back in January was to lead a Zentangle session for my fellow volunteers after a training session for spring field trips. That has all be cancelled – of course. I am unpacking the bin I had already prepped: color zipper pouches with square paper coaster tiles, Pigma Pen 05, and pencils. I am going to use the bin to put all the photos I found in decades-old boxes in our basement…put the smaller bin of pouches on a shelf in my office. I couldn’t resist opening one pouch and tangling!

  • Browsing through emails and feeds with suggestions from others re navigating through the upheaval coronavirus is causing. An email from Coursera (lots for free online courses) had several interesting links that I want to pass along:

    • If you or someone you know is learning online for the first time: You can share these 8 tips from our Teaching & Learning team.

    • If you’re looking for ways to keep learning with your kids: Talk with parents around the world and share your favorite resources.

    • If you’re looking for advice about moving in-person learning online: You can reference these best practices from our Teaching & Learning team.

    • If, like Coursera, you and your team are shifting to remote work: You can join others in our community to discuss strategies and share advice.

Gleanings of the Week Ending March 2, 2019

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.

Good News for Eastern Monarch Butterfly Population - The National Wildlife Federation Blog – Now to sustain the improvement into a trend….and stop the decline for the western population.  

Joshua Trees Could Take 200 to 300 Years to Recover from Shutdown Damage | Smart News | Smithsonian – A very sad result of the shutdown.

Physician-targeted marketing is associated with increase in opioid overdose deaths, study shows -- ScienceDaily – Hopefully with the opioid crisis getting more attention…the targeted marketing is reduced or eliminated. The study used data from before 2016. Things have gotten a lot worse since 2016 but maybe there is a lag between prescription opioid use and opioid overdoses.

Rocking Improves Sleep, Boosts Memory | The Scientist Magazine® - A research topic….and maybe a trend in new bed purchases.

America colonization ‘cooled Earth's climate’ - BBC News – More than 50 million people died and close to 56 million hectares (an area the size the France) they had been farming returned to forest. The drop in CO2 is evident in Antarctica ice cores and cooler weather.

The World’s ‘Third Pole’ Will Lose One-Third of Ice by 2100 - Yale E360 – The Himalayas and Hindu Kush mountains are the source of water for nearly 2 billion people. The region has lost 15% of it’s ice since the 1970s. The current estimate is the river flows will increase until 2060 (flooding) but then will decline. There will be more and more bare rock rather than snow covered rock.

Oregon Launches First Statewide Refillable Bottle System in U.S.: The Salt: NPR – It’s starting with beer bottles. Reuse is better than recycle is better than landfill. If given a choice between buying something in glass or plastic…I choose glass.

BBC - Future - The ‘miracle mineral’ the world needs – Phosphorous. Thermic compost piles rather than mineral fertilizers. It’s economical and environmentally a better way.

Top 25 Wild Bird Pictures of the Week – Raptors – As usual – great photographs of birds from around the world.

What happens to the natural world if all the insects disappear? – Big perturbations of food chains. The article ends with a question: If we dispossess them, can we manage the planet without them? It would be a very different planet.

Gleanings of the Week Ending September 1, 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.

Poor sleep triggers viral loneliness and social rejection: Lack of sleep generates social anxiety that infects those around us -- ScienceDaily – Yet another reason that getting enough sleep is important to us as individuals and society at large.

The Armchair Photography Guide to Canyonlands National Park – Island in The Sky | National Parks Traveler – So many of the pictures had snow! It would be good to go when it was not terrifically hot….so any time but summer and even better close to the beginning or end of winter (a little now…not enough to be hazardous).

Stunning Underwater Photos of Microscopic Plankton by Ryo Minemizu – Beautiful, small life.

In Eastern US, adult trees adapt and acclimate to local climate: Tree cores reveal flexibility, more work needed to understand mechanisms -- ScienceDaily – 14 species of trees were analyzed using tree cores from 1940-1980….shouldn’t we look at more recent tree cores too?

Bed Bugs: When Biodiversity Bites – Cool Green Science – Informative….maybe I should check for bedbugs more consistently when I travel. I shouldn’t keep relying on ‘luck’ to avoid a very bad experience.

A Record Year for Measles Cases in Europe | The Scientist Magazine® - When I was a child, the measles vaccines didn’t exist yet. It was awful. Everyone got sick with them and, for some, there were lasting consequences. I was fortunate and survived without lasting damage except for missing enough school that I never quite understood certain volumetric measurements because I completely missed when it was taught.

Which country has the most expensive education? - Are the comparisons really apples and apples…or are there some pears and oranges thrown in? It is about educations but there are a lot of variables beside cost. All countries and parents and teachers struggle with how to make education relevant to students for now and into the future.

Air Pollution Linked to Decline in Cognitive Performance – The study was done in China but I wondered if it was true in other areas of the world with high levels of air pollution (like India). The US could be vulnerable if we relax our clean air standards.

NASA’s OSIRIS-REx begins asteroid operations campaign – We were in Florida in September 2016 for the launch…so I always notice the updates about its progress.

50% of Industrial Climate Change Emissions Tied to Fossil Fuel Companies – An interview with the two authors of a recently released report: Decarbonization Pathways for Mines.
