10 Ways Vincent Van Gogh Continues to Make News, Even Today – An artist that has been ‘newsworthy’ for a very long time. This post about recent instances of ‘Van Gogh mania.’

Measles vaccines save millions of lives each year – Statistics about measles and the impact of the vaccine…history and how the choices we make will have impacts on the future trajectory of the disease.

New River Gorge National Park and Preserve – It became a national park in 2020. I’ve driven through it…stopped at a visitor center…but haven’t experienced it the way I have other national parks.

Forty Years of Change in Louisiana’s Wetlands – Images from Landsat 9 from 1985 and 2024 show that much of the wetland has transitioned to open water….reshaped by storms and sea level rise.

In healthy aging, carb quality counts - The researchers analyzed data from Nurses' Health Study questionnaires collected every four years between 1984 and 2016 to examine the midlife diets and eventual health outcomes of more than 47,000 women who were between the ages of 70 and 93 in 2016. The analysis showed intakes of total carbohydrates, high-quality carbohydrates from whole grains, fruits, vegetables, and legumes, and total dietary fiber in midlife were linked to 6 to 37% greater likelihood of healthy aging and several areas of positive mental and physical health.

Wildlife Photographer Captures Mid-Air Battle of Two Birds Fighting for Dinner – The battle over a vole between a Northern Harrier and Short-eared Owl in British Columbia, Canada. Dramatic photos. Both birds are over Missouri Prairies in the winter too!

How the humble chestnut traced the rise and fall of the Roman Empire - According to researchers in Switzerland, the Romans had something of a penchant for sweet chestnut trees, spreading them across Europe. But it wasn't so much the delicate, earthy chestnuts they craved – instead, it was the fast-regrowing timber they prized most, as raw material for their empire's expansion. And this led to them exporting tree cultivation techniques such as coppicing too, which have helped the chestnut flourish across the continent.

China’s Mega Dam Project Poses Big Risks for Asia’s Grand Canyon - China’s plans to build a massive hydro project in Tibet have sparked fears about the environmental impacts on the world’s longest and deepest canyon. It has also alarmed neighboring India, which fears that China could hold back or even weaponize river water it depends on.

Step Into a Painstakingly Recreated 3D Model of the Parthenon, Now Restored to Its Ancient Glory - By combining archaeology and technology, a researcher has shed light on a longstanding architectural mystery: how the ancient Greeks experienced the inside of the Parthenon, the Athenian Acropolis’ largest temple, built and dedicated to the goddess Athena in the fifth century B.C.E.

How Tikal Became One of the Greatest Mayan Cities—and Then Vanished - Nowadays, the ruins of Tikal, an ancient Maya city in northern Guatemala, have been largely reclaimed by the jungle. Howler monkeys jump from pyramid to pyramid. Bats hide in the crevices of abandoned homes. Bullet ants and tarantulas crawl along the forest floor while coatis—racoon-like animals with long, upright tails—search for fallen fruit. Many of the city’s structures remain unexcavated to ensure their preservation. Tikal began life as a series of small, unassuming hamlets. Across centuries, it grew into one of the largest and mightiest cities in the loosely affiliated network of municipalities that made up the Maya civilization. At its peak, which approximately lasted from 600 to 900 C.E., Tikal comprised an area of roughly 50 square miles, 3,000 stone structures, and a population that may at one point have exceeded 60,000 people. While other Maya settlements like Chichen Itza remained inhabited well into the 12th century C.E., Tikal is thought to have collapsed around the year 900.

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.

How to Easily Catch Spotted Lanternflies Using a Water Bottle – These insects have invaded Maryland, but I haven’t seen them yet. Maybe this is a reason to put an empty plastic water bottle in the car – just in case.

There is a lot of battery research going on now …coming up with batteries that will help achieve the grid storage and transportation needs of the future.

Young People Are Anxious About Climate Change And Say Governments Are Failing Them – It’s not just young people that have this anxiety. Everyone I know has climate change anxiety….and say governments are failing us all.

Wind energy can deliver vital slash to global warming – It’s a component of the technology we need….it can’t solve everything alone but we have it ready to deploy now – and should just do it as quickly as we can. And it’s cheaper than using fossil fuels!
