The benefits of trees – From an architect’s perspective…working with trees rather than just around them.

How the color orange got its name – Orange was my mother’s favorite color for many years. She had the door of the house they built painted orange! So - this post caught my attention. In English, before the turn of the 16th century, orange objects would be simply known as “yellow-red” or “geoluhread” in Middle English. There are also records of the word “saffron” being used to as a replacement for “orange” as a descriptor. Oranges, the fruit, take their name from the Sanskrit nāraṅga meaning orange tree. Nāraṅga morphed via the Persian word nâranj and the French pomme d’orenge, meaning “apple of the orange tree.”

Quality time with Pocket Gophers - Pocket gophers spend most of their lives underground. There are some 38 species found across a wide swath of central and North America. In many areas, they’re abundant. And yet, many people have never seen one.

Scientists shocked to discover new species of green anaconda, the world’s biggest snake - Green anacondas are the world’s heaviest snakes, and among the longest. Predominantly found in rivers and wetlands in South America, they are renowned for their lightning speed and ability to asphyxiate huge prey then swallow them whole. New research upends scientific understanding of this magnificent creature, revealing it is actually two genetically different species. The snakes are well-adapted to a life lived mostly in water. Their nostrils and eyes are on top of their head, so they can see and breathe while the rest of their body is submerged. Anacondas are olive-colored with large black spots, enabling them to blend in with their surroundings. The two species of green anaconda look almost identical, and no obvious geographical barrier exists to separate them. But their level of genetic divergence – 5.5% – is staggering. By comparison, the genetic difference between humans and apes is about 2%.

Helping caregivers help people with dementia eat at home - Over 80% of people with dementia in the United States live at home. An estimated 60% of home-based patients aren't able to routinely eat or prepare food on their own. Professionals recommended:

  • Lowering auditory and visual distractions.

  • Eliminating household clutter, clearing pathways and improving lighting.

  • Providing written instructions to guide patients' mealtime activities.

Untraceable ingredients and unrecycled packaging: Why sustainable skincare is so hard to find - Short of a chemistry degree, understanding how to make sustainable skincare choices is no easy task for consumers.

Escaping HomeOne of the last birding field trips we did before moving from Maryland was along the Harriet Tubman Byway. The post includes an image of the area from NASA’s Landsat 9 and historical background.

Peek Inside the Ancient Egyptian Tomb of Neferhotep, Now Open to the Public - Revitalizing ancient artifacts is no easy lift. All the wall paintings, reliefs, and sculptures required stabilizing loose stone fragments, cracks, detached plaster, and paint layers, not to mention cleaning and preserving surfaces damaged by fire and time. The restoration project started in 2000.

Discovering Mammoth Cave’s Oceanic Past - Creatures that lived in an ancient seaway that covered the landscape known today as Kentucky some 325 million years ago: crinoids, horn coral, brachiopods…small dark slashes that indicate shark teeth…a dorsal fin spine…a large piece of shoulder skeletal cartilage.

Saguaro Arms and Other Cactus Musings in Tucson – Remembering Saguaro National Park from my daughter’s graduate school years in Tucson. The research about the arms is interesting: The working theory is that saguaros start their branching at a certain size, not a certain age. Initial data indicates that saguaros tend to grow their first arm facing the south or southeast, often when they’re around 11-feet tall. Second arms often grow facing north. Arms seem to grow in a way that maintains symmetry and allows the saguaro to keep its balance.

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.

2021 Year In Review: Top Stories From The National Parks – Lots of perspectives in these ‘top stories’ – lots of challenges but some room for hope in 2022.

Earth in 2021 – A 3-minute video summary from NASA….lots of before and after catastrophic events. The text in the post has a short description of the events in the video.

Top 25 birds of the week: Birding! – Bird photographs…always a great look.

Stopping dementia at the nose with combination of rifampicin and resveratrol – The research was done in mice…they started preparation for human clinical trials in November. If it is effective in humans and can be produced/distributed economically, it could be a boon for aging populations around the world.

Saguaro National Park – A place I visited frequently while by daughter was in Tucson for graduate school. It’s interesting how they are monitoring the keystone species in the park…concern is that fewer young saguaros are surviving these days.

Climate-driven weather disasters inflicted billions in damage in 2021, study says – The cost of climate change already is impacting economies around the world….doing something to reduce/mitigate climate change is quickly becoming the option that makes the most economic sense for everyone.

Poison Ivy – You don’t want to touch it…but it’s best left alone when it’s growing in a place where people are unlikely to contact it. Its berries provide food for birds in the winter, it does not hurt the trees it climbs, and its leaves turn red in the fall.

Chalk steams: why ‘England’s rainforests’ are so rare and precious – This article brought back memories of wading in chalk bottomed creeks in the Dallas, TX area when I was teenager. I don’t remember much about the plants and animals…more about the fossils weathering out of the chalk.

2021 Year In Review - Another Year of Photography During The Pandemic – Beautiful places…and some little photography lessons too.

The year in chemistry: 2021’s biggest chemistry stories – 2021 was quite a year for big chemistry stories! Several of them are likely to have high impact for years to come.

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.

Ice sheet uncertainties could mean sea level will rise more than predicted -- ScienceDaily – There are warning signs that the current models aren’t accurately predicting ice sheet dynamics.

How mail-order frogs could save Colombia's amphibians - BBC Future – Carefully breeding frogs to keep them from going extinct in the wild.

Meet Amanda Gorman, the U.S.' Youngest Inaugural Poet | Smart News | Smithsonian Magazine – Leading with eloquence and hope for the future….pushing us to strive for a country that is a ‘more perfect union.’

House Agrees Saguaro National Park Should Grow By 1,200 Acres – Hope this happens…when my daughter was in Tucson we enjoyed this park many times.

Diet and lifestyle guidelines can greatly reduce gastroesophageal reflux disease symptoms -- ScienceDaily – Exercise seems to be important – perhaps because it helps clear stomach acid that causes heartburn symptoms.

Top 25 birds of the week: Wild birds Photos! - Wild Bird Revolution – Birds – always great to look at in the wild and in photos.

How Codebreaker Elizebeth Friedman Broke Up a Nazi Spy Ring | Smart News | Smithsonian Magazine – Some history…about how a woman did work she wanted to do…made significant contributions…didn’t get credit or pay that she should have. It happens again and again. We can’t assume that it isn’t still happening just because we have some very visible examples of women with power, recognition, and pay.

Are sleep trackers accurate? Here's what researchers currently know – It’s not always good to track sleep….particularly if it causes anxiety. I am in the group that generally has good sleep, so the tracker data doesn’t cause me anxiety, but it probably doesn’t improve anything either!  I might get a much simpler tracker next time that doesn’t provide sleep metrics.

The Wintertime Wonder of Unusual Ice | Smart News | Smithsonian Magazine – The short video of hair ice forming is interesting.

How Africa's largest city is staying afloat - BBC Future – Lagos, Nigeria. Part of the city is known as the ‘Venice of Africa.’ And there is a ‘Great Wall of Lagos’ to reinforce the coast.  The claim is that Africa’s largest city is leveraging its ingenuity to stay afloat….but whether it succeeds in the coming decades will be the real test.
