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.

Arctic river channels changing due to climate change – The prediction was that Arctic rivers would be destabilized by atmospheric warming…that thawing permafrost would weaken riverbanks causing faster channel changes. Using 50 years of satellite data for areas of Alaska, the Yukon and Northwest Territories (which is experiencing the sharpest atmospheric warming due to climate change), researchers have discovered that greening of the area due to warmer temperatures has caused the riverbanks to be more stable…decreasing the sideways migration of river channels by 20% in the Western Arctic!

US Energy Storage Made Record Gains Last Year – A good new story! Something I didn’t know too: “they US remains the largest demand market for energy storage in the world.”

A pool at Yellowstone is a thumping thermometer – The water vibrates…the ground shakes. The intervals between reflects the amount of energy heating the pool at the bottom and how much heat is being lost from the surface.

Awe-Inspiring Videos Show Powerful Ospreys Diving in Pursuit of Prey – Photographer Mark Smith’s Osprey pictures/videos. I saw this post and the photographer was mentioned in the composition class I was views on the same day!

Crocodiles are uniquely protected against fungal infections. This might one day help human medicine too – Crocodiles have unique defensins (components of white blood cells and mucous membranes) that are inactive at neutral pH (as in the blood) but are active in sites of infection where the pH is lower (i.e. acidic). There is a lot more research and trials between this finding and application to humans.

'All work, no independent play' cause of children's declining mental health – The reduction has happened over decades. I was surprised by the quantification: “Between 1950 and 2010, the average length of the school year in the U.S. increased by five weeks. Homework, which was once rare or nonexistent in elementary school, is now common even in kindergarten. Moreover, by 2014, the average time spent in recess (including any recess associated with the lunch period) for elementary schools was just 26.9 minutes a day, and some schools had no recess at all.”

Mesa Verde National Park has plan to save Spruce Tree House – The area has been closed since 2015 because of concerns that layers of sandstone could peel away from the arch at any time. There is a lot of work involved and the plan is current open for public comment. When we visited Mesa Verde back in 1980, it was still open to visitors. Mesa Verde is still a National Park I would like to revisit.

Toxic red tide is back in Florida – Another deterrent to making a road trip to Florida….although it appears that right now there are no red tides in the panhandle…which would be the closest destination for us…I’m thinking maybe Pensacola.

Here Are the Incredible Winners of the 2022 World Nature Photography Awards – A little eye-candy for this week. ‘Fungus Horizon’ is my favorite.

Heat pumps for every home – A good introduction to heat pumps. I want a variable speed heat pump that uses the existing ducts in my house!

Browsing Natural History Magazines – March 2021

/

I browsed the 1966 to 1984 volumes of The American Museum of Natural History’s magazine available on Internet Archive in March 2021. There will be more browsed in April. I collected a few images from each volume ... all the volumes are well worth looking through.

In 1966, the infographic (I’m sure they didn’t call it that in 1966) about spider webs was well done

And I enjoyed the bird pictures by Basil Ede.

Then there were images if flowers and mushrooms and Persian artifacts…carnivorous plants, flamingoes… that I picked from the 1967 to 1972 volumes (this was the time period I was in grade 7-12).

In 1973 there were seed pods (lotus, magnolia, London Plane)), a small racoon, fall leaves, and a turkey…marking the seasons.

In 1974 to 1977 my image picks are hermit crabs, volvox, Mesa Verde (which my husband I visited during this time), and a frog. My husband got his undergraduate degree and I was working full time/going to college part time.

In 1978 there were some beautiful images of seeds in flight.

1979 included many articles that were interesting to me: skunk cabbage, Pompeii, and the 17-year cicadas.

In 1980 there was an article about how snakes shed their skin.

The 1981 volume is missing from the Internet Archive collection. In 1982 there were a lot of articles that interested me – about Jack-in-the-Pulpits and lichens…jewel weed and nautiluses….

And then endemic Hawaiian plants and birds. 1982 was the year my husband and I finished our formal schooling…he had a PhD in Physics and I had a MS in Math.

1983 included a great picture of an Egret in Florida…1984 some parasitized caterpillars. 1983 was a pivot year for us because we move away from Texas and to Virginia/Maryland pursuing our careers.

Overall – I enjoy browsing through the annual volumes of this magazine….thinking about what I was doing at the time they were originally published.

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.

Reimaging Neuroscience’s Finest Works of Art – Recreating the work of Santiago Ramon y Cajal’s century old drawings of the nervous system

Top 25 Wild Bird Photographs of the Week #103 –  There is wood duck image near the end of this group….I have never managed a view from the front. This one has the reflection too.

Utilities Grapple with Rooftop Solar and the New Energy Landscape – I’m glad some utilities are adapting in a positive way to renewable energy. If they don’t – I think more people will be motivated to add battery capacity as the technology becomes available and be ‘off grid.’

New Guide: Smart, Sustainable Materials at Home – This is some I’ll take a look at more thoroughly if I am doing any renovations to an outdoor area.

Wind power costs could drop 50%. Solar PV could provide up to 50% of global power – Are solar and wind energy underestimated? They may be getting cheaper and scaling up faster than the most optimistic forecasts of a few years ago. Hurray!

The Smartphone’s Future: It’s All About the Camera – Some tech…just over the horizon but plausible based on what is available already.

Opinion: The Flood Reduction Benefits of Wetlands – There are lots of studies that will come out of the hurricanes that are impacting the US. This one was based on Hurricane Sandy and came out on August 31. It reported that insurance industry models show that during Hurricane Sandy, marshes prevented $625 million in direct flood damage in 12 states….a reduction in property damage by as much as 30% in some states.

Artificial warming trial reveals striking sea-floor changes – When researchers heated up a slice of Antarctic sea bed by 1 degree (Centigrade), changes were visually discernable: some species grew twice as fast in the heated conditions, different animal communities developed…one bryozoan became so dominate on the warmer sea floor that the diversity of species went down. The researchers already have more experiments planned.

Podcast Series Delves into History, Cultures of Mesa Verde – There are three episodes so far (available here) with a plan for additional ones in 2018.

Our Hurricane Risk Models are Dangerously Out of Date – More than half the area flooded by Harvey was ‘outside of any mapped flood zone’! It seems like insurance companies and property owners need a better understanding of risks…and the old models are no longer adequate.

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.

Map of Play – A non-profit that not only builds playgrounds all over the US but also maps the ones they build and others (here). What a great way for families with children to explore the parks where they live….and when they travel!

Could a Bus with Sleep Pods Replace Airplanes? – Right now it only operates between LA and San Francisco…but it has the potential to be a less stressful way to travel than through an airport. What would it be like to take buses overnight and touring cities during the day…gradually moving cross country?

Top 25 Wild Bird Photographs of the Week #99 – Two pictures of peafowl! A male sitting with the tail feathers bunched behind and the head of a peahen!

The Chemistry of Giant Hogweed and how it causes skin burns – Awful plant! We were warned about this plant in Master Naturalist training since there have been some found in Maryland.

5 health benefits of beets – I’ve been enjoying beets from the CSA this year. Instead of always making fruit beety with them, I’ve be using them one at a time: raw in salads, in soups with potatoes (adds color!), and slivered for stir frying with other veggies. I like them well enough, I’ll buy them at the grocery store after the season for them via the CSA is over!

Illustrated timeline presents women’s fashion every year from 1784-1970 – A little history. I remember from the late 50s onwards and was making many of my own clothes from the mid-60s…so the styles for those years look familiar. I made a dress for myself that looked very similar to the 1966 dress about 1967!

The animals thriving in the Anthropocene – A study done by a team based near where I live in Maryland! Mosquitos, cockroaches, rats, deer, house sparrows…a few of the organisms are thriving while others are declining…or even becoming extinct.

Medieval Manuscripts are a DNA Smorgasbord – Much can be learned from the debris scraped away during cleaning of old manuscripts: DNA from bookworms and humans plus the animals that became parchment. So – we learn history from the physical aspects of manuscripts as much as well as from the words on the pages!

Magnificent Photos of Canyons Carved over Millions of Years –  Antelope Canyon and Canyon X…in Arizona. My husband already wants to plan a vacation to the place.

Ancient DNA used to track Mesa Verde exodus in 13th century – Another item in the gleanings for this week about a place near Antelope Canyon…Mesa Verde. When I visited years ago, the mystery of where the people went was unresolved although many assumed they came part of the Pueblo peoples in New Mexico. This study used DNA of turkeys! Evidently the Mesa Verde people raised turkeys for feathers and food…and they took the turkeys with them when they migrated to the Northern Rio Grande area north of Santa Fe, NM.
