Woman Uses Hidden Cameras to Get Candid Look at Birds in Her Backyard – Birds (and squirrel, chipmunk, and groundhog) at the food bowl.

Climate Change Hurting Water Quality in Rivers Worldwide – Cycles of heavy rainfall and drought are impacting water quality everywhere.

Large amounts of sedentary time linked with higher risk of dementia in older adults, study shows – The average American is sedentary for about 9.5 hours per day! This study found that the risk of dementia begins to rapidly increase after 10 hours spent sedentary each day for people over 60 years old, regardless of how the sedentary time was accumulated.

The puzzling link between air pollution and suicide - More than 700,000 people kill themselves worldwide every year, according to the World Health Organization (WHO). People in the US might be particularly troubled to learn that the suicides here have increased by around 40% over the past two decades….and the nation now has one of the highest rates of wealthy, developed countries. Suicide disproportionately affects men. In the US, around 80% of suicides last year were male. More research is needed to understand the link between air pollution and suicide…but we already know that "tiny, invisible particles of pollution penetrate deep into our lungs, bloodstream and bodies…and are responsible for about one-third of deaths from stroke, chronic respiratory disease, and lung cancer, as well as one quarter of deaths from heart attack."

Archaeologists discover 1,000-year-old mummy in Peru – Long hair still preserved.

Older adults with digestive diseases experience higher rates of loneliness, depression - While life expectancy rates for older Americans are rising, nearly 40% of adults report living with a digestive disease of some kind.

A Chronic Itch: Burrowing Beneath the Skin - Approximately 20% of people suffer from chronic itch, which is medically defined as an itch lasting greater than six weeks. For many, there is no relief. Itch has historically been one of the most overlooked medical symptoms, reflected in the limited available treatment options, most of which have only been discovered recently.

Puffins Are Making a Comeback in Maine - The fifty-year effort that helped puffins rebound in Maine is cause for celebration!

Capturing carbon in savannas: new research examines role of grasses for controlling climate change - Grasses accounted for over half of the soil carbon content across tropical savannas, including soils directly beneath trees. In general, forests primarily store their carbon in the woody trunks and aboveground leaves. In contrast, a significant portion of carbon in grassy ecosystems, such as savannas and grasslands, is stored in the soil, primarily within the extensive root systems of the grasses as well as decaying organic matter. In the context of long-term carbon storage, carbon retained in soils proves to be more reliable, particularly for a vulnerable future marked by warming and increased likelihood of drought and wildfires.

Watch a Deep-Sea Squid Carry Hundreds of Pearl-Like Eggs – A video from the Monterey Bay Aquarium.

It’s a trap: managing cowbirds to save songbirds – The strategy of trapping cowbirds (a brood parasite) to help endangered songbirds along the Santa Clara River in Southern California has evolved to reduce harming other species and cost less.

Electric vehicle buyers want rebates, not tax credits – Of course….immediate rebates rather than waiting for months to get a tax credit are much more appealing.

Urban waterways: discovering the hidden beauty of a Jersey River – River restoration across the country…with the Cooper River story in more detail.

Universal influenza B vaccine induces broad, sustained protection – A new kind of vaccine….using nanoparticles. Perhaps this new technology will lead to an effective universal flu vaccine.

The sustainable cities made of mud – A little construction/architectural history….that could be applied more often.

10 Weird Australian Marsupials You’ve Never Heard Of – So many unusual animals…Australia has more than just kangaroos and koalas!

Cancer probably killed world’s first known pregnant Egyptian mummy – 2,000 years ago a young woman died…and was mummified. The Warsaw Mummy Project has determined that she was pregnant – the fetus was ‘pickled’ in the highly acidic and low oxygen environment of the mummified womb – and the woman probably died of nasopharyngeal cancer.

More Electricity from Wind and Solar than Nuclear for 1st time in USA – Hurray! Wind and solar accounted for over 25% of the nation’s electricity in the first 4 months of 2022!

Loss of male sex chromosome leads to earlier death for men – What? Y chromosome loss happens in 40% (estimated) of 70-year-old men. The loss occurs primarily in cells with rapid turnover, such as blood cells. And it might lead to heart muscle scaring…and then heart failure.

20 Months in COVID-19 pandemic

20 months is a long time for a world crisis to be sustained…but the pandemic is still not over. It does appear that the US has crested the Delta Variant wave and the overall risk level in most areas of the country has declined over the past month. Vaccines and boosters are approved for more people recently too so I got a booster before I left on my road trip.

I am realizing that my cancer diagnosis would have come about 6 months earlier had I not made the decision to delay my annual physical until the vaccines became available and the infections began to decline last summer. I am relieved that the type of cancer I have is not a fast-growing kind; the prognosis is still about the same as it would have been: high probability of successful treatment.  There are probably a lot of people that made similar decisions about their health care during the pandemic and the already strained medical system is now dealing with the backlog of treatment while also addressing the ongoing pandemic.

It was good to be in the rivers again with high school students (volunteer gig for me). I enjoyed it more than ever before both because of the locations and because of the attitudes of the students. They seemed keen to participate…more focused on the field trip…grateful to be back in school. It was easy to be their guide!

There was home maintenance that was not a disconcerting as earlier in the pandemic. The normal checking of our heating system was less stressful…everyone wearing masks. Almost everyone has gotten used to wearing them indoors. We also had a crew trim our trees….for the first time. Our house is ready for winter.

The trip to Longwood was our first since before the pandemic. It was a good day trip for us although I enjoyed the pre-pandemic version more.

And then I felt confident enough to make another road trip to Texas….still in the mode of carrying all my food for the drive with me and only spending one night in a motel (with an air purifier running in the room). I masked up every time I went indoors for rest stops too.

Overall – we’re coping…I hope the trend continues and the pandemic ends at some point although it seems likely that even if it does there will be enough climate changed induced disasters with enough frequency to keep the anxiety levels spiking. And I normally consider myself an optimist (pre-pandemic, at least); maybe I’m not recovering that outlook yet.

Near the Little Patuxent River

On a recent morning – I headed out to the stream that flows under Broken Land Parkway from Lake Elkhorn just before it joins the Little Patuxent River for a volunteer gig – guiding a stream survey done by high school students. Near the bridge that crosses the stream on the Patuxent Branch Trail, there was muddy trail (poison ivy on each side…glad I had on long pants and high boots) to allow access down to stream. We set up our gear around three tables. There was not much dry area to set them up but the water was shallow. A partner and I guided 10 students to collect and ID macroinvertebrates from one of the tables while other volunteers did the same at two others. We had about 45 minutes….and then we got another group of 10 to do it again.

I took some pictures before and after the students arrived. The steam has a lot of vegetation on the banks but the stream has been eroded  - with some trees toppling over from being undercut by rapidly moving water. It is in an area where there is a lot of impervious surface. When it rains – the water rushes down to the stream where it carries away anything in the eroded channel; there is no connection to a flood plain that to slow down the water. It doesn’t take long for it to run off further downstream because we are in the Pediment rather than the Coastal Plain (i.e. there is always an incline for the water to follow).

The water quality was ‘very poor’ based on the types of macroinvertebrates that we found…however – we found quite a few of the types we found. The stream is not dead. Life holds on tight in this suburban stream.

On the Delaware, A Promising New Era in Cleanup of an Urban River – Like many urban rivers in the US – a lot of progress has been made since the mid-20th century….but there is still a ways to go. Many of the urban rivers are clean enough in some stretches for recreational use….but often not after storms when sewage systems and extra industrial waste might be in the water along with the storm water.

Are you being served? A short history of waiters and servers in restaurants – Many of us are still in the mode of only getting carry out!

Examining the Chemistry of Yellowstone National Park's Thermal Waters – A little chemistry lesson in this post. Many of the hot springs and geysers are basic…mud pots and steam-driven fumaroles are acidic.

U.S. Commercial Rooftops Hold 145 Gigawatts of Untapped Solar Potential – The big challenge is logistical and financial. It seems that a partnership between commercial properties and community/utility solar would be worthwhile. It would be much better to use commercial rooftops than farmland for solar panels and many of the rooftops are in areas that consume a lot of electricity as well.

Record-Breaking 60,000 Flamingos Flock to Southern France -The picture of an adult flamingo surrounded by babies/juveniles caught my attention. I didn’t know that young flamingos are gray!

Unique Activities for Yesterday:

Flu shot. I got to my grocery store’s pharmacy just after they opened at 8:30 AM – got a flu shot. The store was busier than when I do my grocery shopping staring around 6:30….but it was still mostly possible to social distance…and everyone was wearing masks. I’ll stick with the earlier time for my grocery shopping.

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.

Significant role for nitrate in the Arctic landscape -- ScienceDaily – There is much we need to learn about how the arctic ecosystems work today….and what will likely happen as they warm. The carbon and nitrogen cycles will speed up…but how does that translate to the types of plants that will grow there.

The Wild and Scenic Rivers Act at Fifty – Protection of some special places….rivers and the banks.

Artist Paints Imaginary Ecosystems Bursting with Colorful Flora and Fauna – Eye candy for the week! (The paintings are also inspiration for Zentangles.)

A is for Aerosol: Earth Matters – A little tutorial that includes satellite pictures of different kinds of aerosols like volcanic ash, sand/dust storms, fog/haze, smoke.

New NOAA Report Looks at National Coastal Flood Vulnerability – The whole report can be found here. Figure 6 (page 26 of the PDF…14 of the report) shows annual high tide floods days per year from 1950 onward. There is a color skew toward more days in the last decade for many areas. Another flood related article: Flood risk denial in US coastal communities -- ScienceDaily – research about how to move communities from denial to taking mitigation actions to reduce the risk to their community.

Without Birds, Lizards, and Other Vertebrate Pollinators, Plant Reproduction Could Decline by Two-Thirds - Yale E360 – Pollination drops an average of 63% when vertebrates (like lizards, birds, bats, mice) are kept away. Wow! Pollinators are not all insects.

When Going Gluten-Free Is Not Enough: New Tests Detect Hidden Exposure – It’s hard to live a gluten-free diet in the modern world…and that is what 3M people in America are trying to do. This article increased my awareness of how hard it it….and how many people are impacted by celiac disease.

The Sahara Desert Has Grown 10 Percent Since 1920 - Yale E360 – The expansion has happened mostly to the south…during the historically rainy summer months. This is one of the first studies to look at precipitation over the course of a century rather than a shorter time.

Influence of global warming on U.S. heat waves may be felt first in the West and Great Lakes regions | NOAA Climate.gov – Maryland is included in the ‘Great Lakes’ region based on the map; in this area more than half of all heat waves would be predominately due to global warming by the mid-2030s. In the west it happens even earlier (by the end of the 2020s). Lots of people live in those areas and the statistics currently tell us that more people in the US die each year of heat-related illness than any other weather disaster.

Sweet potato history casts doubt on early contact between Polynesia and the Americas -- ScienceDaily – DNA studies of sweet potatoes show something about history…and about its closest wild relative (good for the long-term viability of the domesticated crop).
