Missouri Institute of Natural Science

/

My daughter and I visited the Missouri Institute of Natural Science on Black Friday! Neither of us had been there before even though both of us had heard about it and were interested. We got there just after 11 and spent about 45 minutes looking at their exhibits and shop.

Their triceratops (name Henry) dominates the center of the largest space they have. It is part fossilized bones and part 3-D printed ‘bones’ to make a complete skeleton. Awesome!

There were some 3D printers to the side of the displays…it probably takes considerable time to create the pieces of a complete skeleton; there are pieces of a second dinosaur that they are printing and collecting under Henry.

A prehistoric fish was still in rock. I zoomed in for a closer view of the front fins.

Evidence of past eras of plants were also on display. Pinecones and dawn redwood!

A raptor (dinosaur…not modern bird) egg nest was in one of the cases.

And, of course, there were shark teeth…and modern shark jaws to compare. There were obviously sharks in the past that were much larger than any we have today!

Ammonites….the rock was donated and there no indication where it was found.

The display case of coprolites (dung that has been fossilized) was in a corner of one the museum bathrooms!

There was a case of trilobite fossils. I remember one of my teenage friends being keen to find them!

There is a display of lead mining equipment – part of the history of this part of Missouri.

It was worth the visit and I might take guests from out of town to the place (a good choice on a rainy day!).

There were more people arriving as we were leaving…we headed to lunch. The timing was great since by the time we finished our lunch there was a line out the door of the restaurant (the Black Friday shoppers had worked up an appetite).

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.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance? – A diverse array of microorganisms were found in the hot waters of the Roman Baths. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

The Changing Nature of Wilderness - The U.S. government has begun to acknowledge the Indigenous history of ‘wilderness’ areas and, in some (very few) cases, restored land to native tribes or created co-management agreements.

Nearly 25% of land in Africa has been damaged – What’s to blame, and what can be done - The “big five” drivers of land degradation globally and in Africa are:

  • biological invasions, where plant species have spread outside their indigenous area and disrupted the services provided by ecosystems

  • climate change driven events, such as intense droughts and severe fires

  • extractive activities, such as mining and over-harvesting

  • habitat transformation or fragmentation, including deforestation and poor agricultural practices

  • pollutants such as sulfur dioxide, and eutrophication – where algae and other plants take over plant life.

The Hunt: Genghis Khan’s Final Resting Place - His last wish was to be buried in secret, something his soldiers accomplished in two ways: by killing everyone they met enroute to the gravesite, and then trampling that site under the hoofs of their horses until no trace was left. Although tomb culture, inherited from the neighboring Chinese, was well-established by the time Genghis Khan was born, many were constructed underground, some at a depth of more than 65 feet. Most Mongolians today would prefer that Genghis Khan’s tomb stayed hidden. Not because discovering it would unleash an ancient curse—a superstition that was actually quite widespread in Soviet times—but simply out of respect for the historical figure’s dying wish.

Airplane noise exposure may increase risk of chronic disease - Research has shown that noise from airplanes and helicopters flying overhead are far more bothersome to people than noise from other modes of transportation, and a growing body of research suggests that aircraft noise is also contributing to negative health outcomes.

New fossils show what Australia’s giant prehistoric ‘thunder birds’ looked like – and offer clues about how they died out - While the birds had broad, short toes and hoof-like claws for moving across open ground between bodies of water, their partial reliance on freshwater and new plant growth would have become more difficult as ponds and lakes shrunk and disappeared.

Phoenix Heat Deaths Rose by 1,000 Percent in 10 Years - Relentless heat led to 645 deaths last year in Maricopa County, the most ever documented in Arizona’s biggest metropolitan area. Almost half of the victims last year were homeless — 290 people. Twenty died at bus stops, others were in tents, and an unrecorded number of people were found on the pavement, prone as if on a baking stone.

Warming Brings Early Bloom to Bulgarian Rose Fields – Bulgaria is a top producer of rose water and rose oil. To produce these goods, pickers must harvest the flowers early in the morning, when their petals are richest in oil. After a mild winter and warm spring, pickers in Bulgaria’s Rose Valley have headed to the fields around three weeks earlier than normal.

How Storm King Art Center Became One of World’s Top Sculpture Parks – Adding to my list to consider seeing if I travel to New York (state).

Dirt Cheap Batteries Enable Megawatt-Scale Charging Without Big Grid Upgrades Right Away – Hope the technology trend continues…that this idea helps us transition to more electric trucks and other vehicles.

Extreme Birding: Shorebirds at the Sewage Lagoon – Maybe a great place for birding….if you can stand the smell. The same thing happens at landfills.

The human brain has been shrinking – and no-one quite knows why - The brains of modern humans are around 13% smaller than those of Homo sapiens who lived 100,000 years ago. Exactly why is still puzzling researchers. I was a little surprised that the authors did NOT consider the challenge of birthing babies with larger heads (i.e. until C-sections allowed mother and baby to survive if the baby’s head was too large, both mother and baby died) which would result in natural selection of genes for smaller heads.

Climate change is most prominent threat to pollinators - Pollinator populations are declining worldwide and 85% of flowering plant species and 87 of the leading global crops rely on pollinators for seed production. The decline of pollinators seriously impacts biodiversity conservation, reduces crop yield, and threatens food security. Changes in water and temperature associated with climate change can lower the quantity and quality of resources available to pollinators, decrease the survival of larvae or adults, and modify suitable habitats.

The deep ocean photographer that captured a 'living fossil' – In 2010, Laurent Ballesta was the first diver to photograph a living coelacanth. In 2013, Ballesta and his team returned and encountered multiple coelacanths, spending up to half an hour in their presence. Thanks to Ballesta's work, we now know the coelacanth is among the longest-living fish species, with a lifespan of around 100 years, and has one of the slowest life histories of all marine fish – so, like deep-sea sharks with a reduced metabolism, the coelacanth grows slowly, taking as long as 69 years to reach sexual maturity, and with a gestation period of around five years.

Under stress, an observer is more likely to help the victim than to punish the perpetrator - It takes more cognitive effort to punish others than it does to help them. Studies show that when witnessing an act of injustice while stressed, people tend to behave selflessly, preferring to help the victim than to punish the offender.

Stunning Aerial Photos Capture the Abstract Beauty of Iceland’s Glacier Rivers – Iceland….blue.

These tricks make wind farms more bird-friendly – Migratory birds can crash into wind turbines…but there are ways to reduce the carnage: adding high visibility reflectors and spirals to cables, not building wind farms in flight paths, painting one blade on each turbine black (or stripes of black on each blade), and sound.

Swarms of miniature robots clean up microplastics and microbes, simultaneously – Interesting idea. While the bots were decontaminated and reused…they were not as effective…so more work is needed.

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.

Photography In the National Parks: My 10 Favorite Shots From 2021 – I only went to one national park in 2021: New River Gorge (in West Virginia). There are so many beautiful National Parks to see…and they’re worth seeing again and again.

Big Gulp: Blue Catfish Eat Wood Duck – We’ve seen fishermen catch blue catfish at the base of Conowingo Dam (we’re there for the bald eagles). They are huge…sorry to learn that they eat ducks.

Top 25 birds of the week: Raptors! – How many of these live in your area of the world?

Air Pollution Makes It Harder for Bees to Sniff Out Flowers – Not just a problem for bees…also moths, hoverflies and butterflies are having a harder time. This results in a 14-31% reduction in pollination among plants exposed to polluted air.

Ocean microplastic pollution may be greater than estimated – Not a good trend…and this form of pollution that is new enough that the full impact is still being discovered.

With Fewer Animals to Move Their Seeds, Plants Are Stuck in Threatened Habitats – Another way the world is becoming less resilient at a time when climate change is pushing all life to use all the resilience available.

Large Permian Basin Methane Leaks Are Causing As Much Climate Pollution as 500,000 Cars – It’s frustrating that the oil industry has not been a better steward of resources they are extracting for energy. The methane leaks are a waste of the effort put into extraction….and bad for the planet too.

Dinosaur food and Hiroshima bomb survivors: maidenhair trees are ‘living fossils’ and your new favorite plant – Learn more about the ginkgo tree! There is one along my walking route in my neighborhood and others I find in local gardens and parks near where I live. They are so different from other trees…worth noticing.

North Sea Fossil Fuel Companies Plan to Invest More in Wind than Oil Drilling – Hurray! Maybe other companies around the world begin to do this too….a strategic move for Shell, Total and BP.

Antimicrobial resistance now a leading cause of death worldwide, study finds – This challenge will increase over time…if we don’t take action to slow the development of resistance and develop new antimicrobial techniques (maybe we need more strategies than simply trying to develop new antibiotics).

94% of older adults prescribed drugs that raise risk of falling: From 1999-2017, more than 7.8 billion fall-risk-increasing drugs were prescribed to older adults in the US, and deaths from falls doubled -- ScienceDaily – In my 50s, my doctor prescribed a blood pressure medication that made me dizzy. When I complained about it (citing the danger of becoming dizzy and falling down stairs being a greater risk than the benefit of lowering my blood pressure to the level she was attempting), she decided I didn’t need the medication since I was taking half the lowest dose tablet. I hope that the medical professionals prescribing the fall-risk-increasing drugs are more careful about how they are using them now for older people particularly…but for younger people too. Sometimes it seems like the trend is to always ‘treat with drugs’ to address a specific problem rather than integrating for the overall health of the individual.

Health declining in Gen X and Gen Y, US study shows -- ScienceDaily – The long-term trends are not positive; the US was already seeing decreases in life expectancy and increases in disability/morbidity pre-pandemic. The study pointed to the increase in unhealthy behaviors over the past decades that medical treatment cannot overcome. Based on the response to public health measures attempted in the US for the pandemic, it’s difficult to be optimistic that any kind of intervention could be broadly effective.

Identifying sources of deadly air pollution in the United States -- ScienceDaily – Focusing on fine particulates associated with heart attacks, strokes, lung cancer, and other diseases…about half comes from burning fossil fuels; the other half is from animal agriculture, dust from construction and roads, and burning wood for heating/cooking. Ammonia is one pollutant that is not regulated as much as the others and yet it causes a 5th of all deaths caused by fine particulates. It could be reduced with targeted manure management and improving formulations of cleaning supplies, paints, and inks, etc.

Results group into 3 types of biosignatures: biomineralization, tissue, and phylogenic.

Infographic: What Social Isolation Can Mean for the Brain | The Scientist Magazine® - I wondered if the brain structural observations were a cause or effect (or neither). Does the observation that people who are lonely have smaller amygdalae because that are isolated or because they were born that way and it wouldn’t matter if there were a lot of people interacting with them…they would always feel lonely/isolated.

A Silk Road Renaissance - Archaeology Magazine – Many more commodities than silk on the ‘silk’ road: jade, glass, spices, metalwork, ceramic….and missionaries. And the Sogdians were the people that made it work from the 5th to 8th centuries. Panjakent, in modern Tajikistan, has been excavated since the 1940s; many murals have been found depicting myths, fables and everyday life of the Sogdians. In 755 a failed Sogdian coup against the Chinese emperor and thereafter incursion of Arabs from their west caused the culture to fade.

Unique Activities for Yesterday:

Blue Jay Behavior.  There was a blue jay on the deck railing making noise….fluttering its wings…making eye contact with 3 or 4 other blue jays around at the time. Those other jays seemed to ignore the ruckus and flew away. Then the bird flew down to the floor of the deck to look for seeds. Maybe it was a fledgling wanting to be fed by the adults…but the adults were forcing the young bird to find its own food? I’m not sure…but I enjoyed witnessing the minute or so of action…whatever it was about. Maybe it was the same jay that tried to get seed from our bird feeder a few days ago (and failed).

Summer Camp Volunteering – week 2

/

The theme for last week’s Howard Count Conservancy’s summer camps was ‘Fantastic Beasts.’ I spent a morning at Mt. Pleasant and the next morning at Belmont. At Mt. Pleasant there were three groups of campers….45 minutes for each. I used the dinosaur and mammal track rock found at NASA Goddard (saw it back when I was in the HOLLIE program) to initiate the conversation about extinct animals and fossils. There were some fossil shells from Calvert Cliffs and some of the campers had been there to explore themselves. I had on my ammonite shaped earrings too.

2019 07 IMG_5059.jpg

Then for some action: Two pans of water, a measuring tape and white board. A person put one foot into each pan (shoes on) and then stepped out and walked normally. The measurement team (usually two campers) measured heal print to heal print to determine the walking stride length. We measured the walking stride of the tallest and shortest in each group (and then everyone else because everyone wanted to know their stride length…or game it and take extra-long steps!). In the oldest group of campers, we measured the running stride (heel first and on toes). It was a great activity to further explore what information can be gleaned from tracks.

We transitioned into evidence of animals living today with some whelk shells and egg cases found on a beach. Some campers were surprised that the whelks were animals that still live in the ocean along the east coast of the US.

2019 07 IMG_5062.jpg

One of the junior counselors had participated in a dinosaur dig in Montana…and shared some pictures for her adventure with the campers.

It was a busy 45 minutes!

At Belmont, there were two groups of campers making Zentangle® tiles. I introduced the session using the NASA Goddard rock, the welk shells and my ammonite earrings….and then showed them patterns for beasts. The first group (younger) made octopus/jelly fish and tracks. The second group experimented with an ammonite type pattern, tracks and shells. The theropod tracks were the most popular. Many made some big therapod tracks and then some small ones (moms with babies). A variation from one camper: a therapod track….then a blank area where the therapod flew….then more tracks. One camper made mammal tracks. Both groups enjoyed adding colors after they made their patterns with the black Sharpie ultrafine pens.

So many great books available all the time…and free. Reading used to be a much more expensive activity!

2018 08 ebook1.jpg

Brongniart, Adolphe. Histoire des végétaux fossiles, ou, Recherches botaniques et géologiques sur les végétaux renfermés dans les diverses couches du globe. A Paris et a Amsterdam: Chez G. Dufour et Ed. d’Ocagne. 1828. Available from Internet Archive here. This book includes many illustrations of plant fossils – imprints on rocks. It’s written in French – but the illustrations are the reason it’s worth a look. It was probably one of the first paleobotany books ever written. The author produced the book in his late 20s…must have had access to a sizable collection.

2018 08 ebook2.jpg

Karageorghis, Vassos. Ancient Art from Cyprus - The Cesnola Collection in The Metropolitan Museum of Art. New York: Harry N. Abrams, Inc. 2000. Available from Internet Archive here. This is a more recent book (I am glad that many copyright holders that have out-of-print books are making them available this way). The color illustrations are wonderful. I particularly like utilitarian objects.
