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.

Heat Pumps Are Still a Good Investment Even If Your Grid Is Powered By Coal - If every American home with gas, oil, or inefficient electric resistance heating swap those things out for heat pumps, the emissions of the entire U.S. economy would shrink by 5% to 9%. That’s how powerful a decarbonizing tool heat pumps are.

Asian Elephants Bury Their Dead - In India, five dead elephant calves were found buried on their backs in irrigation ditches, with evidence that multiple herd members had participated in the burials. Are there more examples? It doesn’t seem likely that elephants would be able to move an adult elephant like they did the calves. Do they do something else with the carcass rather than burial?

COVID-19 virus can stay in the body more than a year after infection – So – if it persists in blood, should these people not be donating blood? Does this mean that people could get COVID from a blood transfusion?

Archeoastronomy uses the rare times and places of previous total solar eclipses to help us measure history – What we learn from historical eclipses….a timely history lesson with the 4/8 total eclipse that will be visible from much of the US coming soon.

An Eruption for Galápagos Iguanas – The La Cumbre volcano is erupting in the Galapagos. Some satellite views from NASA including a description of the instrumentation available to monitor this eruption.

An obsessed insect hunter: The creepy-crawly origins of daylight savings – We did it again last weekend…changed to daylight savings time. I wish we could stop (don’t care whether we stay permanently on standard or daylight savings…just that we don’t change) but we don’t seem to be able to stop. This post is about George Hudson…and his desire for more daylight after work to study insects! I’ll browse some of his books on Internet Archive.

Solar Accounted for More Than Half of New Power Installed in U.S. Last Year - Solar accounted for most of the capacity the nation added to its electric grids last year. That feat marks the first time since World War II, when hydropower was booming, that a renewable power source has comprised more than half of the nation’s energy additions. Texas and California led a solar surge driven mostly by utility-scale installations, which jumped 77 percent year-over-year to 22.5 gigawatts. The residential and commercial sectors also reached new milestones. The biggest open question is how quickly projects can connect to the grid.

An inside look at Beech tree disease – A fast spreading disease….killing another tree species. It hasn’t been that long ago that Emerald Ash Borer wiped out the ash trees. We were just noticing sickly beeches in Maryland before we moved…realizing that the forests would be profoundly changed without beech trees.

Professional Photographer Shares How to Photograph the Great North American Solar Eclipse Safely – Time to start preparing for 4/8/2024!

America’s Sinking East Coast – There are multiple reasons that areas are sinking faster than melting ice and thermal expansion from climate change would cause.

Dickerson Park Zoo

/

We made our first visit to Dickerson Park Zoo last week. It’s on the north side of Springfield MO – the closest zoo to where we live. We got there about an hour after their opening; the close parking lot was almost full…others taking the advantage of the cooler than usual August morning.

Colorful birds seem to dominate my pictures. Many times, I was photographing through fencing; sometimes you can see the blur/shadow of that barrier.

The preening Scarlet Ibis was one of my favorites. The surprise was seeing the nictitating membrane (an eyelid that is hinged on the inner side of the eye and closes horizontally across the cornea).

Flamingos were in the same enclosure as the ibis – feeding and preening. They feed with their bill toward their bodies. One of the birds had a range of colored feathers.

In the trees above the flamingoes, there were several roseate spoonbills. Their bodies are colorful…their heads and large bills are bare – at odds with the body.

Peacocks (and pea hens) roam the zoo; they are relatively acclimated to people. There were no males with full tails. All the birds I saw appeared to be juvenile birds (younger than 3 years).

There were two Gray Crowned Cranes. I had seen similar birds at the St. Louis Zoo too. The birds at Dickerson Park Zoo were better positioned for a photograph!

The turkey enclosure had one male and a lot of hens…some immatures as well. I heard a mother telling her child that it was a mom and babies; I guess she thought the male was the ‘mom’!

Black swans are dramatic. The pair seems to have more ruffled feathers than I expected.

There were several parrots; we heard them before we saw them! The one I photographed was using its beak like an appendage for balance as it moved around its enclosure.

There were two types of tortoises in different parts of the zoo with signage that they bite! The first one was large but not giant…and I was intrigued by the pattern of the shell…plates like flatted pyramids.

The second was a giant tortoise --- looking well fed!

There were monkeys – somehow they tend to look sad to me. The one I photographed had companions that were moving about, but he was sitting still.

The zoo was working on the giraffe exhibit (they usually have giraffe feedings) so we did not see them like they would normally have been out and about in the morning.

The zoo has a rescued bald eagle – large but one of its wings was not right. It didn’t move from its perch but kept a watchful eye on movements outside its enclosure.

There were metal statues for climbing on (with signs warning that the statues might get hot in the summer) and backdrops for photographs.

There was one elephant with the explanation that when the matriarch died, the two remaining females did not get along…so they each are outside on their own. They get socialization time off exhibit with a male elephant.

There were other animals to see but not easily photographed. The big cats and bears were either in their dens or sleeping.

We didn’t ride the train (I photographed it with a giraffe sculpture in the foreground) – but I like that it is available – another dimension to a visit to the zoo that we might try on a future visit.

The Dickerson Park Zoo might be my favorite. It is not overwhelmingly big or crowned…and its design provides plenty of shade along the paths.

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.

The 'Zoom Boom' Can't Save the Midwest – People are leaving dense, high-cost urban metro areas…but very few of them are going to the heartland.  Maybe some of the areas will benefit from migration because of climate change. Or maybe the Midwest should simply focus on investments to help their economies and create places people want to live….do the groundwork to encourage people to move to the region.

Poison Mushrooms: How to Tell – From the Natural History Society of Maryland…good pictures.

The Avenues of America – An overview picture of Washington DC taken from the International Space Station.

The Invasion Of The National Park System – Quagga mussels, Burmese pythons, feral swine, household pets gone wild, tamarisk trees….and those are just the ones pictured!

Incredible Footage of Iceland’s Fagradalsfjall Volcano – And there are people in many of the pictures to provide scale!

Major advance in fabrication of low-cost solar cells also locks up greenhouse gases – There are so many articles about technologies that sound promising toward creating faster pathways away from fossil fuels….hope a lot of them move forward.

Elephant Trunks Can Suck Water at 330 Miles Per Hour – Wow

Pyramid made of dirt is world’s oldest known war memorial – Located in Syria…and at least 30 people – male and presumed to be warriors – buried in horizontal steps.

COVID-19 pandemic has been linked with six unhealthy eating behaviors -- ScienceDaily – Eating disorders are one of the deadliest psychiatric health concerns and 6 of them have a correlation to the pandemic: mindless eating and snacking, increased food consumption, generalized decrease in appetite or dietary intake, eating to cope, pandemic related reductions in dietary intake, and re-emergence or marked increase in eating disorders.

How flooded coal mines could heat homes – Evidently the water in the mines could be tapped as a source of geothermal heating/cooling!
