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 Home – One 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.

Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs – Ancestors of orchids, magnolia, and mint all shared Earth with the dinosaurs…and are thriving today.

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.

100 Top Photographers Sell Prints to Benefit Ocean Conservation – Enjoy the photography….and participate in the fundraiser for the oceans.

Methane must fall to slow global heating – but only 13% of emissions are actually regulated – I was surprised that so little is regulated…and even when regulation exists it is sometimes not fully implemented.

Capping Oil & Gas Wells in Texas Could Create Tens of Thousands of Jobs - CleanTechnica – A way to reduce methane!

280,000 Photos Used to Create Highly-Detailed Image of the Moon – So many images…stitched together…colorized. The blog post includes a short description of how it was done.

Talking puppy or finger puppet? 5 tips for buying baby toys that support healthy development – Not surprisingly…in most cases, traditional toys provide better interactions and experiences then technological toys for 0-2 year olds.

Beatrix Potter’s famous tales are rooted in stories told by enslaved Africans – but she was very quiet about their origins – Thought provoking. There is considerable evidence that Beatrix Potter knew about the Brer Rabbit stories (books from her father’s library) and that she used the stories to create Peter Rabbit!

Chronic stress can inflame the gut — now scientists know why – Chemical cues produced in the brain….immune cells in the gut. For people with Inflammatory Bowel Disease (IBD) (includes ulcerative colitis and Crohn’s disease), stress might make treatments less effective…and can prompt flareups in patients what previously were responding well to medication.

Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists -- ScienceDaily – There is a need to understand how microbes respond to the disruption of drought in both agricultural and natural areas. Right now, soil holds more carbon that plants and the atmosphere combined….so it is important that we understand enough to effectively intervene if the soil starts releasing more of its stored carbon.

Getting to the Root of Skin Healing | The Scientist Magazine® - Research that indicates that hair follicle transplantation might accelerate wound closure, reducing scar formation, and remodeling existing scar tissue.
