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.

How a Soviet swamp rat scheme for Azerbaijan went horribly wrong – Nutria introduced in the 1930s…..destroying every wetland in Azerbaijan today.

Light Pollution May Be Keeping Honey Bees Up at Night - On hot nights honey bees will sleep outside and slept less/more fitfully if there is artificial light…which could undermine the health of the colony.

The next massive volcano eruption will cause climate chaos — and we are unprepared – The history of large eruptions and what we can determine about the aftermath…though provoking on what it would be like if a massive eruption happened in the modern world.

Carbon recycling instead of plastic trash – Using iron electrocatalysis and producing green hydrogen as a biproduct…can be powered by solar panels. I hope this can be commercialized near term. We are overwhelming our world with plastic trash!

CT Scans Unlock Secrets of Mummified Individuals at Field Museum – Respect for the ancient dead…but still studying their bodies.

How do countries measure immigration, and how accurate is this data? - Three types of migrants who don’t have a legal immigration status. First, those who cross borders without the right legal permissions. Second, those who enter a country legally but stay after their visa or permission expires. Third, some migrants have legal permission to stay but work in violation of employment restrictions. Most high-income nations have a small minority of irregular immigrants in their immigrant population; the exception is the United States which estimates 22% of their immigrants are irregular.

Riding The Rails on Amtrak's Cardinal Line Through New River Gorge – Maybe a relaxing way to see the National Park and Preserve…thinking about next fall.

Mother Tiger Teaching Cub How to Fight Wins Nature’s Best Photo Awards – Great pictures….but Patricia Homonylo’s video is the most thought provoking….the one that is a call to action.

Geologists rewrite textbooks with new insights from the bottom of the Grand Canyon - From the Tonto Group's 500-meter-thick strata, we're learning about sea-level rise and the effects of catastrophic tropical storms -- probably more powerful than today's devastating hurricanes -- during a period of very hot temperatures when the Earth was ice-free.

Quantifying How Urban Trees Cool Cities - The authors of a new study estimate that the city of Baltimore could reduce land surface temperatures by 0.23°C if they increased tree canopy by 1%. To achieve 1.5°C of cooling, they would need to increase tree canopy cover by 6.39%.

Ten Little Celebrations – October 2024

/

The temperatures were more pleasant in October….I enjoyed the outdoor field trips and classes a lot more.

Pleasant temperature to walk around the Missouri campus during class. We were outdoors longer but it was easy compared to short hikes around campus in August and September!

Field trip to a healthy stream and woodland. Celebrating the water quality and the native species (not overcome by invasives)!

Cut down a Japanese barberry and burned most of it. Celebrated one more non-native (that is sometimes invasive) being gone from my yard.

Geology field trip plans. I celebrated that enough of my Missouri Master Naturalist classmates and chapter are interested in geology field trips to make them a likely late fall/early winter activity.

Getting seeds planted. I got buckeye, Hopi sunflower, common milkweed, and persimmon seeds during the second week of October….and celebrated when I got them planted. Some must go through the cold temps of winter to sprout in the spring.

Volunteering at a fair for homeschoolers…talking about Monarch butterflies. I celebrated by first gig as a Missouri Master Naturalist…and that my iPad-based slideshow of Monarch butterfly pictures was well received.

Owl Pellet. I vaguely remember that I had dissected an owl pellet in some previous training…but I celebrated that I did a more thorough job this time… and found a complete rodent skull…and the backbone…lots of ribs.

First solo Missouri Master Naturalist volunteer gig. I celebrated that the two days spent doing an after-school program with a local school for gift students was positive for them…and for me!

Whataburger. Sometimes I just want to splurge. On the way back from my Dallas trip, I stopped for a Whataburger…celebrated that it tasted just as I remembered - although I won’t do it very often.

Successfully completed my Missouri Master Naturalist training. Hurray! I am celebrating what I learned and that I now have more time to volunteer!

Missouri Master Naturalist Training – Week 8

/

Week 7 of Missouri Master Naturalist consisted of two sessions: a lecture on Fungi that was part of the monthly chapter meeting and two lectures in our regular class: Snakes of Missouri and Endangered Species and Conservation. I took notes during all three! I particularly enjoyed the photographs in the fungi lecture, the snake experiences from a place we had visited for a field trip, and the example used for talking about endangered species (freshwater mussels). I still have a lot of materials from the Missouri Department of Conservation that were on the handout table to browse through from the regular class: salamanders, snakes, mushrooms, lizards, crayfish, toads and frogs, caves and karst, Missouri fishes.

During week 8, I also took action to learn more about Missouri geology on my own since it is not a topic that was covered in the training….starting with two books: Roadside Geology of Missouri by Charles G. Spencer and Geology of Missouri State Parks by Max W. Reams and Carol A. Reams. The second book is the most current – copyrighted in 2022; about 25% of the books is an overview of Missouri geology and then there are sections for state parks by physiographic region. I’ll start with the state parks since it seems safer than stopping at road cuts…although I might keep the Roadside Geology in the car for when my husband is driving, and I can observe as we are on the road.

Next week is graduation week! The time has flown by. I have an evaluation form that I am completing this weekend.

Who Was Buried in Spain’s Megalithic Necropolis of Panoría? - More women than men were buried in Panoria, where human remains were interred in collective burials between 4,100 and 5,600 years ago.

On Navajo Lands, Ancient Ways Are Restoring the Parched Earth - Traditional rock and stick structures, similar to those used by Native peoples long before Europeans arrived on the continent, are not only delivering water to crops they are also restoring the watershed and those of neighbors, helping to sequester carbon, and reviving this high-desert ecosystem…. an opportunity to begin developing localized food economies.

Megadiverse flowering plant family on isolated islands – A high number of evolutionary events -- occurred in the aster family (daisies, sunflowers, and asters) within relatively short time periods on many islands worldwide.

Why is Mount Everest so big? New research highlights a rogue river – but deeper forces are at work - Everest is around 250m taller than the other great peaks of the Himalayas. It is also growing by about 2mm each year – roughly twice as fast as it has been growing on average over the long term. The Arun river’s course changed around 90,000 years ago, eroding away rock that was weighing Everest down – and the mountain has bounced up in response, by somewhere between 15 and 50m. However, the “fundamental cause” of the peak’s size is the tectonic processes that create mountains.

Researchers Grow an Extinct Plant From a 1,000-Year-Old Seed - Israeli researchers have grown the seed of a previously unknown species of flowering plant into a mature tree. In the late 1980s, archaeologists excavating caves in the northern Judean desert discovered a well-preserved but mysterious seed that had likely been carried there by animals. The seed could be dated to between 993 C.E. and 1202 C.E. and that it was a unique member of the commiphora family, a flowering plant known for its aromatic resins. Chemical analysis of the leaves shows an abundance of medical properties in the leaves, and its lack of fragrance matches descriptions of the tsori in the Bible.

Rare and Elusive Australian Bird, Once Thought Extinct for 100 Years, Discovered by Indigenous Rangers and Scientists – Night parrots are generally difficult to detect—a fact that has been long recorded in Indigenous culture. The elusive species creates tunnels and nests in dense spinifex bushes and emerges at night to forage for seeds.

5 things to know from this week’s big report on cannabis - A new report from the National Academies of Sciences, Engineering and Medicine finds the disconnect between the states and the federal government is leading to fragmented policies, and risks to the public. 5 takeaways:

  1. People consume cannabis more regularly than alcohol in the U.S.

  2. Weed and vapes can be super potent and that’s not always disclosed

  3. You can get psychoactive hemp products even in states where cannabis is illegal

  4. Research on cannabis is stifled

  5. Cannabis can be dangerous, but people hear more about its benefits than risks

Biodiversity Becoming a Top Priority - A survey of 300 landscape architects, designers, and landscape architecture educators in the U.S. found that 96 percent of landscape architects are familiar with the impacts of the biodiversity crisis. 45 percent have made biodiversity conservation a top priority of their practice and another 41 percent consider biodiversity as part of their organization’s environmental ethos.

Medical imaging breakthrough could transform cancer and arthritis diagnosis - A new hand-held scanner developed by University College London researchers can generate highly detailed 3D photoacoustic images in just seconds, paving the way for their use in a clinical setting for the first time and offering the potential for earlier disease diagnosis (cancer, cardiovascular disease, and arthritis). What a boon if this could become the new standard…avoiding waiting for an imaging appointment, having to sit still for a long time, and higher cost of current technology!

Incredible Winners of the 2024 Natural Landscape Photography Awards – Couldn’t resist this collection of beautiful images to finish off the gleanings for this week.

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.

Congaree National Park to Remove Feral Hogs – There were feral hogs in the park when I visited in 2008!

Witness 1.8 billion years of tectonic plates dance across Earth’s surface in a new animation – I watched the video twice…the first just enjoying the overall moves. The second time I watched for how North America moved over time.

What Are the Best Policies for Reducing Carbon Emissions? - A systematic analysis of more than 1,500 climate policies from around the world found that only 63 were successful, reducing average emissions by 19 percent on average. Policies are more effective when implemented with a variety of other policies, instead of alone. In the U.K., banning coal-fired power plants worked when it was combined with tax or price incentives. The same was true for banning combustion engine cars in Norway. The study also found that successful strategies differed between countries—in developed countries, carbon pricing was effective, while regulation was successful in developing countries.

How thyroid hormone fuels the drive to explore - Research in mice sheds light on how thyroid hormone alters wiring in the brain. Findings reveal that thyroid hormone syncs up the brain and body to drive exploratory behavior. Too little thyroid hormone slows down metabolism and can result in symptoms of depression, while too much speeds up metabolism and can lead to symptoms of mania. The receptor for thyroid hormone is expressed by cells throughout the entire brain, including in areas of the cortex responsible for high-level cognition like planning and decision-making.

Cutthroats and Cottonwoods: Protecting the South Fork of the Snake - The South Fork contains the largest cottonwood gallery in the West. In the fall, the leaves on the tall-timbered giants lining the banks bounce in the breeze like gold coins exploding from the pot at rainbow’s end. Native Yellowstone cutthroat trout are in the South Fork. Most of the cutthroats spawn in tributaries contributing to the South Fork but they are found throughout and the farther you float, the bigger they get…. a river that is as it should be. Consistently wild.

Nutrition and healthy aging: The role of protein quality in combatting muscle loss - Aging may reduce our ability to digest, absorb and utilize the nutrients in food. It is important to consider increasing the amount and improving the quality of protein (probably higher than what is currently recommended for the general population) we consume. For example – research showed that consuming higher-quality (whey and pea) protein supplements at breakfast and lunch increased muscle-building in older adults by almost 10 per cent. However, collagen protein — a supplement heavily marketed towards older adults — did nothing to bolster muscle-building in older adults.

Flash Flood Roars Through Frijoles Canyon at Bandelier National Monument – One of my favorite places in New Mexico……hope I can visit again sometime when it isn’t flooded!

Cooler Communities for All - Four key design strategies to reduce urban temperatures:

  • Increase tree percentage in parks and green spaces

  • Provide shade

  • Use plant materials and water instead of hardscape

  • Switch to green ground cover, including grasses and shrubs

This Massive Egyptian Observatory Is Unlocking Celestial Secrets of an Ancient Culture - Archaeologists in Egypt have just uncovered a truly stellar find—a sixth century B.C.E. astronomical observatory in the ancient city of Kafr El-Sheikh. The observatory, made from mud bricks, is the largest and oldest of its kind in the region, spanning nearly 10,000 square feet. It was in ancient Egypt that the 365-day calendar was born, and the 24-hour day. They completely mapped the night sky, and had their own constellations and zodiac, some signs of which are still recognized today.

Looting of the Sudan National Museum – more is at stake than priceless ancient treasures - It was founded in 1959, ahead of the construction of the Aswan High Dam. A Unesco-led salvage campaign was launched in 1960 to protect and preserve the ancient monuments that would be flooded by the dam, which would alter the landscape of the Nubian region. The reported loss of parts of this collection represents a profound and multi-layered tragedy for future generations.

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.

Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes - Food webs are becoming less complex in warmer, nutrient-rich waters. This simplification means shorter food chains and a degraded functioning ecosystem.

Stonehenge’s giant Altar Stone came all the way from north-east Scotland – here’s how we worked out this astonishing new finding – It evidently came from north-east Scotland at least 430 miles from where it is today!

Over half of iron deficiency cases in large health system still unresolved at three years - Factors associated with a higher likelihood of getting iron levels back to normal included older age (age 60 and up), male sex, Medicare insurance, and treatment with IV iron alone. Younger patients, females, and Black individuals were most likely to remain iron deficient or experience longer lags in getting their iron stores back to a healthy level.

What the Mesopotamians had for dinner – Small clay tables date to 1730 BC or earlier…are about preparing food! The instructions are terse, clipped. And as is the case for many old recipes, from all vintages of the human relationship with cuisine, amounts are not specified. Here is how one of the stews is made: for the lamb stew known as tu'hu, first you get water. Then you sear leg meat in fat. In go salt, beer, onion, rocket, coriander, Persian shallot, cumin, beets, water. Crushed leek and garlic and more coriander, for a fiery taste. Then add kurrat, an Egyptian leek. The beets turn it an electric red.

Cleaning up the aging brain: Scientists restore brain's trash disposal system – Using a hormonal like drug to help the glymphatic system of the aging brain to remove toxic buildup more effectively (as younger brains do).

Plant disease could spell apocalypse for citrus fruits - Huanglongbing (HLB), also known as “citrus greening” disease. The economic impacts are dramatic in some countries. In Brazil, production has fallen by more than 20%, 60% in Guadeloupe and plummeted by more than 90% in Florida.

U.S. Wind Generation Hit Record in April, Beat Coal! – Hope this begins happening more often. It should as more wind energy comes online and coal plants are shut down.

Our skin is teeming with microbes. We should learn to love them - Zoom in on any square centimeter of the skin on your body and you'll find between 10,000 to one million bacteria living there. The skin microbiome is second only to our guts when it comes bacterial diversity. This is quite surprising if you think about it. Compared to the safe, warm and moist habitats of our mouths or guts, the skin is an inhospitable place.

Maine! Ghost Plant – A parasitic plant I learned about in my general biology course….and was thrilled the first time I saw it in the wild years ago. I haven’t seen it since.

Five ways science is tackling the antibiotic resistance crisis – Natural products, the promise of AI, combination therapies, immune assistance, efficient diagnostics….and we need more.

Eureka Springs & Northern Arkansas Railway

/

My husband, daughter, and I took a two-day trip to Eureka Springs, Arkansas just before Memorial Day. It’s less than a 2-hour drive from our home in Missouri. The nav system took us on a scenic route…curvy 2 lane highway all the way, with frequent road cuts that were generally well back from the shoulder (I wondered if students on geology field trips use them to see the underlying rock of the area), and over a narrow part of Table Rock Lake.

We arrived a little early and drove through the town. I remembered the main street from more than 50 years ago; the streets that turn off are very steep and narrow up the side of the valley. The place is a driving adventure! We parked in the Eureka Springs & Northern Arkansas Railway just after the terminal opened; we had reservations for the morning excursion train. It was a cloudy morning and had rained recently; the first photographic opportunity of the morning turned out to be butterflies in the gravel parking lot! The mourning cloak on the curb was not moving but all the others took some patience to photograph.

There was collection of old rail cars and engines. I was interested in a tractor that must have been quite a change on farms where horses or oxen had previously done the heavy pulling.

The car and engine that took us on our excursion was waiting for us. They had a ramp mechanism that enabled wheelchair access to the car, but we could also get into the car using stairs.

The train follows a stream, and I managed a few pictures while we were in motion. I saw a pawpaw tree with fruit beginning to grow (but didn’t get a picture); pawpaw is the food plant of the zebra swallowtail butterfly (like I photographed in the parking lot for the train).

The route is only 4.5 miles up and back (and takes about an hour). At the halfway point, we got out and I took some track and vegetation pictures.

The conductor gave us a tutorial about putting pennies on the track as an optional activity for this excursion. My daughter had told us ahead of time (she had done the excursion last fall) so we came prepared. I gave a penny to a man that didn’t have any change with him. We all stood away from the tracks and the train rolled over our pennies – waiting to retrieve our pennies from the track until the conductor got the word from the engineer that it was safe to do so.

Below is a picture of a penny and a train-flattened penny. I am thinking about putting some earring posts on two of the flattened pennies….wearing them as earrings!

It sprinkled a little while we were on the train but had cleared by the time we returned to the station. The train was an excellent start to our Eureka Springs adventure.

Mesozoic Plants

/

The 3 volume Catalogue of the Mesozoic plants in the Department of Geology, British Museum was published between 1894 and 1900…authored by Albert Charles Seward early in his career and earned him membership in the Royal Society at the youthful age of 35. The specimens are from the Wealden beds; the most important finds came from near Hastings. The beds accumulated in a freshwater estuary or lake and include representatives of many plants. The volumes are available on Internet Archive: Vol 1, Vol 2, Vol 3. Seward devoted years to create the catalog: sifting through the fossils…organizing the material…creating images. It was a worthy endeavor and set the trajectory for the rest of his life.

As I browsed these books, I made a game of looking for plants I recognized in the fossils…ferns, conifers, ginkgo-like leaves.

Maryland to Missouri – a road trip as passenger

/

I’ve been making road trips between my home in Maryland to Missouri on my own until recently when my husband went with me to see the house we are buying. It was so different to be a passenger rather than driving myself!

The route was familiar and there were no cold weather hazards this time. More daylight made it possible for us to start the drive before 7 in daylight – leaving behind the fading blooms on the cherry and plum tree in the front of our Maryland home.

The first day of the trek was the easiest; it was cloudy with mists and sprinkles…occasional sunshine.

The daffodils were still in full bloom at the South Mountain rest stop; the elevation makes a difference; the flowers have already faded at hour home closer to Washington DC/Baltimore.

I took a few extra minutes at Sidling Hill to photograph the road cut. It is awesome.

There were plenty of rest stops along the way – a quick walk to the facilities through the damp.

Whatever it is, the way you tell your story online can make all the difference.

And the bridges at Louisville KY.

We stopped for the night at a hotel in Corydon, IN that has a historical marker in its parking lot!

The next day was harder after we were about halfway through the drive – very heavy rain. The early rest stops still held some beauty – trees on ridges, violets and spring beauties and dandelions.

It was safe to take pictures of the arch at St. Louis because I wasn’t driving!

The pictures taken at the rest stops in Missouri were through the window because of the rain. For some reason the fire hydrant near a picnic table tickled me.

And then we were at our hotel…glad that the heavy rain did not include lots of thunder/lightning and high winds that had been part of the forecast.

eBotanical Prints – September 2021

/

21 botanical print books browsed in September and added to the list. They were published over almost 300 years (1793 to 1981). The most recent volumes are documentation of threatened and endangered species. The earliest (Icones plantarum rariorum - Vol 3, sample image) was a volume from a series I had found before – but somehow missed this volume. There were some beautiful illustrations of plants I’m familiar with: tulip poplar, jack-in-the-pulpit, deciduous magnolia, maples, oaks, holly. There were also two volumes of plant imprints…geological botanical prints. I found several volumes that were fruit focused…more to come of those finds in October. Overall – a lot of variety in the September 2021 volumes.  

The whole list of 2,229 botanical eBooks can be accessed here. The list for the September books is at the end of this post.

Performance of the Year | The Prairie Ecologist – Video of an Eastern Hognose Snake pretending to be dangerous.

Millennia-Old Rock Art in Israel Offers Window into Lost Culture | Smart News | Smithsonian Magazine – Monuments 4,000 years old…dolmens. There are more than 400 in the same area. A survey of them started 2012 after the first rock art engravings were discovered (14 trident-like shapes on the ceiling of a large dolmen).

Backyard Birding in Central India to Beat Lockdown – Backyard birding - something that is happening around the world during the pandemic!

Granite tors evidence of ice-free Alaska - The Field - AGU Blogosphere – Tors mark the Pleistocene pathway that was free of glaciers for plants and animals during the ice age.

Great, Warm Lakes – This is an article from a month ago…I’m just getting around to reading it. The surface temperatures were warmer than usual as of July…in some of the lakes there are areas warmer by more than 4 degrees C (including most of Lake Michigan)!

Restoration of Sicily’s Temple of Zeus Continues - Archaeology Magazine  - A 26-foot-tall sculpture of Atlas dated to the 5th century BC…and there might have been as many as 40 such statues.

Winners of International Photo Contest Celebrate the Art of Movement – Capturing a moment…freezing motion.

Blood-thinner with no bleeding side-effects is here – Still work to be done….the current formulation is filtered out by the kidneys very quickly. It has applicability in artificial lungs (used to bridge the time between lung failure and lung transplantation) currently.

Poor Everglades Nesting Season A Result of Climate Change and Untimely Storms – It appears that 2020 isn’t a good year for roseate spoonbills and wood storks in Florida.

This Medieval Potion Kills Stubborn Bacteria – “Bald’s eyesalve” – garlic, onion, wine, cow bile. It appears to be effective at combating antibiotic resistant bacterial strains…biofilms that are particularly challenging to kill…including diabetic foot infections.

Unique Activities for Yesterday:

3 racoons. Our birdfeeder camera made a video of some visitors to our deck just before 2 AM on Wednesday, 8/5: three racoons! They looked smaller than the female that came several times earlier in the summer. Perhaps they were her young….out foraging on their own (maybe she was nearby). They were no more successful than she was getting seed from our squirrel proof birdfeeder! The action started with one up on the deck railing under the feeder and another 2 directly below on the deck floor. The one on the railing comes down almost on top of one that was on the deck floor. The one that was on the deck railing stayed in the video the longest…thoroughly searching under the feeder after going down to the deck floor.

Sycamore branch. Back on August 2nd I posted about a dead branch in our Sycamore tree (picture on the left). My husband discovered the branch on the ground near the base of the tree when he went out to use the weed eater and it took both of us to pulled it to our brush pile at the edge of the forest. It came down without bringing a lot of other branches with it….a little sooner than I expected but probably brought on by the thunderstorms that have been sweeping through the past few days.

20200807_100249.jpg

Yellow wooly bear. My sister sent me a picture of a caterpillar from her garden in Carrollton, Texas. It appears to be a yellow wooly bear that becomes a Virginian Tiger Moth. Evidently, they are common but neither one of us had seen one before.

Radio Tracking a Rare Crayfish – Cool Green Science – There are a lot more species of crayfish than I realized…and they have a bigger role in the stream that I assumed.

Mindfulness for middle school students: Focusing awareness on the present moment can enhance academic performance and lower stress levels -- ScienceDaily – I wonder if ‘mindfulness’ is something we need to teach more overtly now than in the past because technology and daily life tends to push us in ‘unmindful’ ways.

Canadian Canola Fields – I looked at this article because the Bugs101 course that I took recently mentioned the canola fields of Canada (for some reason I had never known very much about Canola as a crop). This article provides more history. It has become a cash crop for Canada in recent decades.

There's a Troubling Rise in Colorectal Cancer Among Young Adults | The Scientist Magazine® - Incidence of colon cancer is falling in older people…but becoming more common in people under 50. It has continued to go up over the past decade. In young adults, the cancer is discovered later too…usually stage 3 or 4.

A Northwest Passage Journey Finds Little Ice and Big Changes - Yale E360 – Lots of changes. Grizzly are moving northward…fewer polar bears…salmon far north of where they used to be…lungworm killing muskox…plastic in ice cores.

Researchers Discover New Family of Viruses | The Scientist Magazine® - The new viruses are found in lung biomes of people that had had lung transplants or have periodontal disease….many times the patients are critically ill. But we don’t know yet if the new family of viruses are linked to disease.

Utah's red rock metronome: Seismic readings reveal Castleton Tower's unseen vibrations -- ScienceDaily – On the plus side – it does not appear that climbers of the tower are impacting it…but this work is a baseline and there could be some longer term effects. Wikipedia has some pictures and a short article about Castleton Tower.

Infographic: History of Ancient Hominin Interbreeding | The Scientist Magazine® - Still learning about the hominin tree and how modern humans carry the genetic heritage.

Camera Trap Chronicles: The Pennsylvania Wilds – Cool Green Science – I wonder what I would see coming through my back yard. I know we have deer…and I occasionally see a fox. Maybe racoons. My first though was to put a camera on the bird feeder or the bird bath.

BBC - Future - Is there a worst time of day to get sick? – Circadian rhythms are important to health….and our medical system doesn’t use them to advantage. I remember being concerned when my mother was in the hospital years ago and the lights were very bright day and night. No wonder she had difficulty sleeping!

Researchers uncover indoor pollution hazards -- ScienceDaily – Some surprises: pollutants change with temperature inside the house….and time of day makes a difference. Formaldehyde seems to be particularly prevalent. These studies are scary for existing homes. We need work on mitigations that homeowners can implement…and new construction that reduces the source of pollutants.

Infographic: Immunity Isn't the Body's Only Defense System | The Scientist Magazine® - Symbiotic bacteria, metabolism and pathogen mutation examples overlay the immunity strategy. As we learn more, we realize that the human body is more complex that we realized.
