Gleanings of the Week Ending August 31, 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.

A 13,600-year-old mastodon skull is unearthed in an Iowa creek - Researchers will now scrutinize the bones to look for “any evidence of human activity, such as cut marks.”

Wildlife Photographer Captures Intimate Photos of Alaska’s Grizzly Bears – The bears of Lake Clark National Park. Wildlife photographers from around the world started coming to the Kenai Peninsula in Lake Clark National Park around 15 years ago, but they can’t get up close to the bears without a trained guide close by.

Solar Energy Revolution Brewing In Arkansas, With An Assist From GM - As of Q1 2024, Arkansas ranked #27 on the state-by-state rankings of installed solar capacity tracked by the Solar Energy Industries Association. One area that has seen some healthy activity is rooftop solar and other small-scale projects. According to the figures kept by SEIA, a single utility-scale solar project in Chicot County accounted for an outsized share of the 1,122 megawatts of installed capacity (140 megawatts). Last week GM announced that it has entered a PPA for electricity from the largest ever solar energy project in Arkansas so far, the Newport Solar project. Located in the town of Newport, the 180-megawatt project comes under the umbrella of the firm NorthStar Clean Energy, a branch of CMS Energy.

Say 'aah' and get a diagnosis on the spot: is this the future of health? - Analyzing the color of the human tongue. The proposed imaging system can diagnose diabetes, stroke, anemia, asthma, liver and gallbladder conditions, COVID-19, and a range of vascular and gastrointestinal issues.

The weird way the Los Angeles basin alters earthquakes - The enormous five-mile-deep (8km), sediment-filled basin that LA is built upon plays a surprising role in the effects felt above ground. Imagine the Los Angeles basin as a giant bowl of jelly – the dense rocky mountains and underlying rock make up the bowl, while the sediment fill is represented by the gelatinous mixture. If you shake the bottom [of the bowl] a little bit, the top flops back and forth quite a bit. And atop this quivering mass of jelly is the megacity of Los Angeles. Other cities built on basins: Seattle, Portland, Salt Lake City, Mexico City, and Tehran.

Rethinking the dodo - The Dodo was the first living thing that was recorded as being present and then disappeared. Researchers went through all the literature on the Dodo encompassing hundreds of accounts dating back to 1598 and visited specimens around the UK, including the world's only surviving soft tissue from the Dodo, in the Oxford Museum. They confirm that the bird was a member of the columbid (pigeon and dove) family. Contrary to previous assumptions about its demise, it was almost certainly a very active and fast animal.

Elite Woman’s Grave Found in an Abandoned Fortress in Mongolia - The fortress of Khar Nuur was part of a system of walls and fortresses that spanned nearly 2,500 miles. Radiocarbon dating of the burial indicates that it dates to between A.D. 1158 and 1214, after the fortress had been abandoned, and likely between the fall of the Khitan or Liao Empire in A.D. 1125 and the rise of the Mongolian Empire in A.D. 1206. The researchers explained that the burial is one of only 25 graves dated to this period that have been found in Mongolia. The woman was between the ages of 40 and 60 at the time of death, and she was dressed in a yellow silk robe and headdress made of materials likely imported from China. Her coffin, made of non-local wood, also contained gold earrings, a silver cup, a bronze vessel, a gold bracelet, and coral and glass beads.

The banana apocalypse is near, but biologists might have found a key to their survival - Today, the most popular type of commercially available banana is the Cavendish variety, which was bred as a disease-resistant response to the Gros Michel banana extinction in the 1950s from Fusarium wilt of banana (FWB). For about 40 years, the Cavendish banana thrived across the globe in the vast monocultured plantations that supply the majority of the world's commercial banana crop. In the 1990s, a new strain of the Fusarium fungus started causing problems….and the research race was on to save bananas.

Florida is building the world's largest environmental restoration project - In February 2023, a large digger broke ground on a multi-billion-dollar project that has been decades in the making: building a reservoir the size of Manhattan Island. The reservoir, which is part of an historic restoration of the Everglades ecosystem, is intended to help bring a secure, long-term supply of clean drinking water to Florida's residents. The whole project is due to be completed in 2029.

Streetlights Helping Trees Defend Against Insects - Streetlights left on all night cause leaves to become so tough that insects cannot eat them, threatening the food chain. Decreased herbivory can lead to trophic cascading effects in ecology. Lower levels of herbivory imply lower abundances of herbivorous insects, which could in turn result in lower abundances of predatory insects, insect-eating birds, and so on.

Northern Pacific Railroad eBooks from 1880s

The eBooks of the week are from a railroad company in the 1880s…illustrating some of its routes. They provide a view of some special places of the time – when the west was still somewhat ‘wild’ but developing rapidly with the extension of railroads and more people coming. Enjoying browsing these books on Internet Archive!

The Wonderland route to the Pacific coast (1885)

 I think about where my ancestors were at the time these books were published. One side of the family was still in Bohemia (Europe) – not emigrating to the US until a decade later. The other side was already in the US and mostly in Missouri.

Characteristics of older forests can buffer effects of climate change for some bird species – Results from an 8-year study (2011-18). Forests can provide refugia for some species….our stewardship is important.

Ruby was the first Black child to desegregate her school. This is what she learned – I’m glad she survived and thrived….don’t want any child going through this type of experience in the future. Education is challenging for child without accompanying trauma from the community or institution or bullies.

Should you feed garden birds? – Right now we have 2 bird feeders and baths…with a few plants in the yard that attract birds as well. Over the next few years, I will be planting for the birds – native plants that will support insects the birds need particularly during their breeding season…produce pollen and nectar and seeds to round out their diet.

Earth’s Iconic Waves, observed by Landsat – A 3.5 minute video about places on earth where the waves are significant enough to be visible from satellites…and a little about why those spots produce the types of waves observed.

The sands of Mars are green as well as red, rover Perseverance discovers – The discovery of volcanic rocks on Mars rich with large grains of olivine! I remember going to a green sand beach on the big island of Hawaii – olivine on earth.

Enhanced Geothermal Technology Cracks The 24/7 Energy Code – Maybe a technology that will be as important as wind and solar in our renewable energy portfolio.

What older adults do while they sit affects dementia risk – Passive behaviors like watching TV increased dementia risk-- on the plus side active behaviors while sitting like reading and using computers reduced dementia risk. The study had more than 145,000 participants aged 60 or over with nearly 12 years of follow-up.

Cataracts: we’re working on eye drops to treat them so people don’t need surgery – Glad the research is happening…probably not fast enough to be available when my cataracts will require treatment.

When Told About Flood Risk, Homebuyers Shun Vulnerable Homes, Study Finds – I shouldn’t be a surprise that people don’t want to buy properties that flood….and there are a lot of expensive coastal properties that have an increasing flood risk.

Rockwell Kent illustrations

Earlier this summer I browsed two books written and illustrated by Rockwell Kent and available on Internet Archive. According to the Wikipedia entry, he spent an extended period in Alaska (1918-19) and Tierra del Fuego (1922-23) so the art in these books emerged from being immersed in a place rather than a quick visit.  He is quoted as saying ‘I want to paint the rhythm of eternity.’

I selected two images from each book but there are many more that are just as appealing in both books….worth the time to take a look. These are not the typical illustrations of adventure and travel; they skew toward a deep inner journey….the place being a backdrop.

Wilderness; a journal of quiet adventure in Alaska (1920)

Alaska Ablaze – 5,000 lightning strikes…dozens of wildfires.

How to turn your garden into a carbon sink – Turning more yards into gardens…with more diverse plantings….a few more trees. Sometimes going a little wild is a good thing!

Pollen and Heat: a looming challenge for global agriculture – heat is a pollen killer for canola, corn, peanuts, and rice. It is becoming more important than ever for crops to bloom before the temperature rises…and it is getting more challenging as multi-day stretches of excess heat are becoming more common early in the growing season.

The life of a solitary bee – There are as many as 4,000 bee species in the US….and most of them are solitary. 98% of the native bee species in the US are solitary.

AccuWeather shares how an electric school bus fares in Alaska – Evidently the bus has done well even at -48 degrees Fahrenheit!

Musings from the parks: Navigating National, Wild, Recreational, and Scenic Rivers – Prompted by a proposal to refine limits on the horsepower boaters can use in Ozark Scenic Riverways in Missouri…a look at regulations at other rivers in the National Park System. I’d prefer that we begin the transition to electric motors (if motors are allowed at all) rather than only focusing on horsepower.

Epidemiologists develop advanced state-of-the-art tool for measuring the pace of aging – A blood test to measure the pace of biological aging…with the possibility of identifying interventions that would slow aging… and attempt to build aging health equity.

Alaska’s Vegetation is Changing Dramatically – The impact is still to be determined but rapid changes are rarely good for ecosystems….they decline because they can’t adjust fast enough to the rate of change.

Bees' buzz is more powerful for pollination, than for defense or flight -- ScienceDaily – There is not just one kind of buzz! And some bees (like honey bees) don’t buzz flowers at all.

Top 25 Birds of the Week: Raptors  - The birds of prey…some are powerful looking, some are cute, some a ugly…but that’s just overlaying our stereotyping onto birds like we do with other people.

Why Plastic Waste is an ideal building material – We need a strategy to upcycle all the waste plastic that is accumulating since we don’t seem to be able to wean ourselves from plastic packaging at all.

Grand Canyon's Prehistoric Past Appears In 313-Million-Year-Old Tracks -  Sandstone rockfalls….near the trail…first spotted by a Norwegian geology professor on a field trip to the Grand Canyon with his students.

Unique Activities for Yesterday:

Clothes dryer working. Our 20-year-old clothes dryer has a new heating element and the dust/lint has been cleaned out from around the innards. The first loads we did were towels!

Doe and 2 fawns in our back yard. My husband noticed the deer in our back yard in the afternoon. They stayed around long enough for me to get some pictures. In past years we’ve had a doe and 2 fawns in our yard more frequently. This year their main path back into the forest must be through another yard because we haven’t seen them as often…and so it is a special day when we do.
