Gleanings of the Week Ending June 27, 2026

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.

06/17/2026 Science Daily Scientists say most of what’s in your food is still a mystery - Most chemicals in food are invisible to us in terms of research. We consume them every day, but we have little idea what they do. Projects such as the Foodome Project are now attempting to catalogue this hidden chemical universe. More than 130,000 molecules have already been listed, linking food compounds to human proteins, gut microbes and disease processes. The aim is to build an atlas of how diet interacts with the body, and to pinpoint which molecules really matter for health.

06/17/2026 The Conversation Levels of ‘forever chemicals’ in dolphins and whales are rising globally - Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Some dolphin studies have reported changes in immune-related markers associated with PFAS exposure. The highest concentrations tended to be found in coastal dolphins and porpoises, suggesting animals living near urban and industrial areas face greater exposure.

06/15/2026 Smithsonian Magazine Venus Flytraps Snap Their Traps Shut in Less Than a Second - A team reports that the chomping motion happens when rigid walls of cells on the leaves’ outer surface suddenly soften. The findings provide new insights into plant biology and could inspire new robotic designs.

6/16/2026 The Conversation Microplastics are everywhere in Pennsylvania’s water – but the tide may be turning - Microplastics are nearly everywhere, their concentration in sediment has been doubling every 20 years, and some of the most common types are among the most toxic. More than 80% of mismanaged plastic waste - plastic that’s littered, dumped or otherwise not properly contained - is estimated to be transported by rivers to coastal environments. What can you do to decrease your exposure to microplastics and help decrease their spread? You can stay informed about which plastics carry the greatest health risks and check the recycling number on the bottom of containers before you buy. You can also swap out single-use plastic cups, straws and food containers for alternatives, such as glass, stainless steel or unbleached paper.

06/11/2026 NASA Air Pollution’s Daily Pulse Over the Northeast - More than 35 million people live along the New York–Washington corridor and breathe the region’s air. While air quality has improved significantly in recent decades, outbreaks of ground-level ozone remain common, particularly in the warm summer months, when the chemical reactions that produce the pollutant accelerate and stagnant air allows ozone to accumulate. A reminder of this seasonal phenomenon came earlier than usual in 2026, when a mid-May heat wave prompted the New York State Department of Health and the New York Department of Environmental Conservation to issue a health advisory on May 17 over concerns about ozone.

06/13/2026 Clean Technica Solar & Storage Provide Over 90% of All New Power Added to the U.S. Grid in Q1 - The United States added 7.8 gigawatts (GW) of new solar capacity in the first quarter of 2026, surpassing 6 million cumulative installations as solar remained the leading source of new power added to the grid. Despite changing tax policy and regulatory actions targeting clean energy, solar and energy storage represented 91% of new capacity installed in Q1 as utilities, homeowners and businesses seek energy security amid global gas and gas turbine supply disruptions.

03/17/2026 National Geographic To study microplastics, Cassandra Rauert first had to build a plastic-free lab. It wasn't easy - An air-locked, 250-square-foot facility built almost entirely from stainless steel and nicknamed “the submarine”—though it feels less like a sub and more like a starship from a galaxy where plastic never took over modern life. Known as the Minderoo Plastics and Human Health Laboratory

06/09/2026 Science Daily An invisible forever chemical rain is falling across the planet - Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tons of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to keep rising. Scientists are still working to fully understand the long-term effects of TFA. The European Chemicals Agency classifies the chemical as harmful to aquatic life. Researchers have also detected TFA in human blood and urine. In addition, the German Federal Office for Chemicals recently proposed classifying TFA as potentially toxic to human reproduction.

06/09/2026 National Wildlife Federation Data Centers are Driving Up Your Energy Bill - Clean energy has become the cheapest form of energy, but wind and solar still only account for 17 percent of the country’s energy generation. The biggest barrier to deploying clean energy is usually transmission. Without enough transmission to deliver cheaper clean energy to where it’s needed, over 900 GW of solar and wind projects sit waiting in queue, and utilities often default to more expensive fossil fuel generation instead. We can double down on outdated systems that pollute our air and water and drive up prices, or we can invest in the resilient energy solutions that have proven to be the cheapest, build the grid needed to deliver them, and ensure the largest electricity users pay their fair share of the costs they trigger.

06/08/2026 National Parks Traveler Young Mountains, Old Rocks: A Geological Overview of the Teton Range - The Tetons continue to grow. The tectonic forces that built the range are still active, and stress continues to build even if the Teton Fault has not experienced major movement in recorded history. Evidence of ongoing stress appears east of the Teton Range, where the Snake River does not flow down the center of its riverbed. Instead, the river flows preferentially along the western side of its banks as the extensional stress builds and the eastern block of the fault (the block underlying Jackson Hole) tilts more westward.

Anna Scripps Whitcomb Conservatory

The Anna Scripps Whitcomb Conservatory is on Belle Island (in the Detroit River). It is the oldest continually-running conservatory in the US….opening in 1904. The original wood framing was replaced with steel and aluminum in 1949. My daughter and I stopped to see it on our road trip from our homes in Missouri to London Ontario.

The place is filled with interesting plants. It was challenging to get wide views from the relatively narrow walkways other than looking upward.  

I quickly reverted to macro type photographs.

Some plants interested me so much that I took multiple images of the same plant.

Curly crotons were new to me.

The Venus flytrap and pitcher plants were inside a terrarium type structure that somehow made it even easier to photograph them.

The cactus room was one of my favorites…my theme was to photograph the various configurations of cactus spines.

The conservatory is not the largest I’ve toured…but it probably packs more plants into its space than any other! Tomorrow’s post will be about the grounds around the conservatory (including a koi pond) and the aquarium.

Gleanings of the Week Ending February 20, 2021

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.

Top 10 things we learned about climate change in 2020 – I’m thinking about this more this week with the extreme cold in Texas…and lack of preparedness of utility companies and state governments. It drives home the overarching message now: doing nothing will cost more than doing something.

Top 25 birds of the week: Seabids! – Birds and water…from around the world.

Size, Shape, and diversity in phytoplankton – The tiny organisms that could be changing in warming, more acidic oceans….do we have enough of a baseline to know if these communities are changing in ways that will impact the food networks of our oceans?

Fairy Shrimp – A video from a vernal pool in Pony Pasture Rapids Park in Richmond, Virginia.

Wintering bird communities track climate change faster than breeding communities in Europe and North America – Weather impacts birds in the short term (my family has commented that they have seen flocks of robins in their neighborhood recently….having not seen them in the past 30 years they’ve lived in the area) but the longer term impacts of climate changes are only observable with large data bases built since the 1980s. This study looked at over 1,200 species of birds!

How to see the red fox in winter – We occasional see red fox in our neighborhood but I haven’t seen any (so far) this winter. Maybe after the snow/sleet is over I’ll take a walk and look for tracks.

Age provides a buffer to pandemic's mental health impact, researchers say -- ScienceDaily – It may not be ‘age’ as much as older people being more able to stay at home and avoid other people (stress reduction through conscientious steps to avoid COVID-19 exposure)….whereas young people are more likely to have to get out and about for work or other obligations. It could be difficult for older people living along…but maybe we have quite a few older people that are not alone in their ‘bubble.’

Sunset Crater's Explosive Past – The youngest of the volcanoes in the 1,800 square mile San Francisco Volcanic Field near Flagstaff, AZ. It’s a place I visited (and posted about) back in February 2015.

Immune driver of brain aging identified -- ScienceDaily – It seems to be a change in how myeloid cells handle glucose….tending to hoard it rather than using it for energy. I wondered if that is why people with diabetes are at increased risk for cognitive decline.

Magnetic fields detected in Venus Flytraps – A small magnetic field is produced when the trap closes!

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.

Planned intermittent fasting may help reverse type 2 diabetes, suggest doctors: And cut out need for insulin while controlling blood glucose -- ScienceDaily – There needs to be follow up study…but if this works, maybe it should be some everyone with type 2 diabetes tries.

10 States Now Get At Least 20 Percent of Their Electricity from Solar and Wind - Yale E360 – Progress! Hopefully other states will join the club and go beyond 30%. During some months in 2017, Iowa and Kansas, wind accounted for over 50% of in-state electricity generation.

Largest ever genetic study of blood pressure -- ScienceDaily – So much for find a root cause for high blood pressure. There are lots of genes and there is overlap with life-style exposures to things like fruit, water, tea, caffeine, alcohol, and salt. It’s complicated!

Too much vitamin A may increase risk of bone fractures -- ScienceDaily – Another study about the danger of getting ‘too much’ via vitamin supplements.

Top 25 Wild Bird Photographs of the Week: Courtship Displays – National Geographic Blog – The treat of bird photos!

Redrawing the Map: How the World’s Climate Zones Are Shifting - Yale E360 – Interesting summary…hardiness zones on the move, Tornado Alley is shifting, the tropics are getting bigger, the Sahara desert is bigger, the 100th meridian has shifted eastward by 140 miles.

The Enchanting History of Notre Dame Cathedral's Famous Gargoyles and Grotesques – The stone carvings are pitted…but the sculptures are still awesome.

BBC - Future - How a daily 10-minute exercise could boost your happiness – The 10-minute exercise is jot down the answer to 6 questions each day: 1) What experiences, however mundane, gave you pleasure? 2) What praise and feedback did you receive? 3) What were the moments of pure good fortune? 4) What were your achievements, however small? 5) What made you feel grateful? 6) How did you express kindness? It’s a good way to end the day on a positive note!

U.S. Air Pollution Deaths Nearly Halved Over Two Decades - Yale E360 – A good trend but there were still 71,000 deaths in 2010 attributed to air pollution – more than traffic accidents and gun shootings combined. Air pollution remains a public health issue.

The chemistry of Venus flytraps in C&EN – I’ve always been fascinated by carnivorous plants. This infographic describes how it take two hairs to trigger the closing of the trap…that it only takes 0.1 seconds to close…and then up to 5 days to digest the insect.
