How the Groundbreaking Suez Canal Forever Transformed the World’s Shipping Routes – The official opening ceremony was on November 17, 1869. It had taken 10 years to build on the path of an ancient canal and was called “the greatest service to the commerce of the world since the discovery of America.” The project was funded mostly by Western Europe.

'Jekyll and Hyde' leaders do lasting damage - When supervisors swing between good and bad behavior, they do even more damage to their employees than ones that are abusive all the time. And there are some indications that this kind of leadership could be contagious, with a leader's volatility fostering volatility in others

Scientists find a 35,000-year-old saber-toothed kitten in the Siberian permafrost - The cat was just three weeks old when it died, but its cause of death is unknown. The kitten still had its whiskers and claws attached when it was pulled out of the permafrost, and was covered in a coat of short, thick, soft, dark brown fur. Its hair was about 20 to 30 millimeters long. When looking at the mummified cub, scientists found some interesting differences between the kitten and a modern lion cub, particularly, in their paws: the saber-toothed kitten had wider paws, but no carpal pads — that's the wrist joint that's help modern day felines absorb shock.

Hatchling Alligators at the Fort Worth Nature Center – The Dallas/Fort Worth area is at the edge of American Alligator range…but the Nature Center has confirmed that it has a breeding population there. The Fort Worth Nature Center is 3,650 acres of mixed habitat, owned and operated by the City of Forth Worth; it is one of the largest city-owned nature centers in the US. There is an alligator research project ongoing there now that the breeding population has been discovered.

Sitting too long can harm heart health, even for active people - 10 hours or more of sedentary behavior per day is associated with heightened risk of heart failure and cardiovascular death. I am so glad that I decided years ago to use a Swopper chair (without a back…bouncing) at my computer desk….so I am moving most of the time that I am there!

Bone marrow in the skull plays a surprisingly important role in ageing - Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflammation and other hallmarks of ageing.

Glaciers Reveal When Volcanoes Are on Brink of Eruption - New research shows that glaciers near active volcanoes flow faster than other glaciers. The findings suggest it would be possible to predict volcanic eruptions by tracking the speed of glaciers.

Can we live on our planet without destroying it? - With eight billion people, we currently use a lot of the Earth's resources in ways that are likely unsustainable. Research shows that humanity can stay within the planetary boundaries. But it seems that there is little political will to do so. A depressing commentary on humanity.

Memories are not only in the brain - In the future, we will need to treat our body more like the brain -- for example, consider what our pancreas remembers about the pattern of our past meals to maintain healthy levels of blood glucose or consider what a cancer cell remembers about the pattern of chemotherapy.

Astronauts of the underworld: The scientists venturing into the deep, dark Earth - Hundreds of cave entrances are known on Earth, the Moon, even Mars. Many have never been explored.

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%.

Air pollution from oil and gas production responsible for $77 billion in annual US health damages, contributes to thousands of early deaths, childhood asthma cases nationwide – Another reason to dramatically reduce the burning of fossil fuels. It’s not just about climate change.

An ‘Epidemic’ of Loneliness Threatens Health of Americans – A mounting problem. Social disconnection has multiple types of cost: economic, health, poorer academic achievement/work performance.

The ocean is hotter than ever: what happens next? – Probably more extreme weather and marine heatwaves…problems for marine life from corals to whales.

Cleanup of inactive Gulf of Mexico wells estimated at $30 billion – The life cycle costs of the fossil fuel industry are much greater than we’ve ever paid (i.e. we haven’t generally paid for clean up costs as part of the cost of fossil fuel based products)…the bill will eventually have to be paid.

Photography In the National Parks: The Invitation of An Intimate Composition – Good tips for more than National Parks! It’s a special kind of landscape photography!

Rare good news from the Amazon: gigantic fish are thriving again – Pirarucu, an air-breathing fish that must rise to the surface every 15 minutes or so…can grow to be 10 feet long, weigh up to 450 pounds…are valued for their meat. The fish are making a comeback thanks to sustainable fishing programs in northern Brazil.

Stunning Winners of the 2022 Landscape Photographer of the Year Contest – Capturing a place…and a tiny amount of time.

Top 10 Discoveries of 2022 – from Archaeology Magazine

Remains of last surviving Tasmanian Tiger discovered in museum cabinet – Finding and following the trail of an older female thylacine that was trapped and sold to the Beaumaris Zoo in mid-May 1936. She died in September 1936. The zoo transferred her body to the Tasmanian Museum and Art Gallery where taxidermist preserved the hide, and the skeleton was broken apart and positioned on 5 cards. Both hide and skeleton were used by the museum for educational purposes…and then forgotten. They were found recently in a cabinet in the museum’s education department.

Best of 2022: Top Astrophotography That Captured the Beauty of the Cosmos – Quite a few from the James Webb Space Telescope.

Volcanic activity increases worldwide – There are 47 volcanoes around the world that are in ‘continuing eruption status’…more than double the normal. The article includes short videos of several of them.

The rich marine life under frozen ice – Phytoplankton and organisms that eat it….discovered by geologists trying to get a mud core, hitting rock, then seeing organisms when they reviewed what the camera on their equipment recorded!

Top Websites for Urban Planning – 2022 – From Planetizen. This year they highlight an increased attention to the social and environmental outcomes of planning…enabling identification/resolution in the intersections between the built/natural environment and the lives of people.

Exploring a forgotten Jewish Land – The Beta Israel in northern Ethiopia. The 100,000 strong population fled to Israel in the 1980s to escape war and famine.

US National Integrated Drought Information System – 68.4% of the US is abnormally dry…46% is in moderate drought…27% in severe drought. Use the location tab of this page to select state or county level maps color coded for their drought status. Where I live, we are in moderate drought.

Autumn in the Adirondacks – Leaf color has not been impacted by the drought in the Adirondacks. The pictures are from the Landsat 9 satellite. I’m enjoying the color from the ground – even with the drought here in Missouri making it not as colorful as it probably was in prior years.

Why cork is making a comeback – The main product mentioned in the article was cork stoppers….but I thought of the calm I felt when I walked into the University of Michigan’s Law Library with a tour group and realized how much the cork floor muffled our footsteps. It was the highpoint of the trip with my daughter when she was considering the school for her undergraduate studies.

Blue fibers found in dental calculus of Maya sacrifice victims – Analysis of more than 100 sacrifice victims found blue fibers in the mouths of 2 of them. Are the fibers from blue gags left in the mouths of victims over and extended time? Similar pigment called Maya blue has been found in other sites where it may have been used to paint the bodies of sacrificial victims. Another archeological mystery…

See the buzzworthy winners of the Wildlife Photographer of the Year competition – Eye candy for the week.

Millions of Americans are losing access to maternal care. Here’s what can be done – 36% of the counties nationwide – largely in the Midwest and South – constitute “maternity care deserts,” meaning they have no obstetric hospitals or birth centers and no obstetric providers. That does not bode well for the health of mothers and the next generation.

These stunning satellite images look like abstract art – and they reveal much about our planet – 8 images selected from US Geological Survey satellite images of the Earth’s surface.

Engineers weave advanced fabric that can cool a wearer down and warm them up – Maybe the ‘cool down’ of this technology (if it can be developed) will help us deal with climate change more effectively. There are already beginning to be more heat related deaths and there will be some occupations that will become impossible without technology to cool the body in outdoor environments.

Rainfall is becoming more intense in most of the US – East of the Rockies…there is increasing precipitation intensity. Water resource management is more challenging. Flooding risk is going up too.

USGS Public Lecture Series – A wide range of topics including volcanoes in Alaska, earthquake early warning for all, migratory big game, droughts and groundwater quality, modernizing the national water information system….and many more. I am beginning to work my way down this YouTube playlist.

The Roots of Violence – Reexamining bones excavated in the 1960s with new 3D imaging techniques….defining the violence of their lives and deaths shown in the bones. There is a history of archeological thinking here too. For a long time, evidently there was a presumption that prehistory was a less violent time…but the evidence is mounting that it was not.

Reducing air pollution: policies that pay off – An analysis done in Europe of the economic benefit of measures to reduce fine particle air pollution from wood heating and transport. It seems that similar type analysis could happen in other places in the world with some variation to tailor the reductions to have the biggest impact.

30 Incredible Winning Photos From the 2021 Nature Photographer of the Year Contest – Some eye-candy. My favorite is the caterpillar ‘walking among fennels’ – a similar scene happened at our CSA the first summer of the pandemic.

Assessing the U.S. Climate in 2021 – There were 20 separate billion-dollar weather and climate disasters that impacted the US in 2021.

Savanna Fire Management Can Fund Africa’s Protected Areas – Another article about the new economics we will need to understand to address climate change.

The forgotten medieval habit of 'two sleeps' – Maybe one long period of sleep is ‘modern’….that humans slept in two phases prior to the industrial revolution. One of my grandmothers developed a ‘two sleeps’ pattern late in her life when she was living alone….and I am beginning to wonder if I will.

The Horned Helmets Falsely Attributed to Vikings Are Actually Nearly 3,000 Years Old – Another look at artifacts…and better dating…and the history derived/assumed previously is changed.

Top 25 birds of the week: bird coloration! – This time of year…a little color from birds is a welcome sight. I’m noticing the ones in my neighborhood: Northern Cardinal, House finches, and red-bellied woodpeckers.

Across the Boreal Forest, Scientists Are Tracking Warming’s Toll – The northern forests becoming carbon emitters….. peatlands are drying out, and hotter, drier conditions are leading to a steady increase in wildfires — all of it accelerating permafrost thaw.

The Legacy Of "Pele's Grandson," Alex Lancaster – Some history of volcano observation on the big island.

The 'Zoom Boom' Can't Save the Midwest – People are leaving dense, high-cost urban metro areas…but very few of them are going to the heartland.  Maybe some of the areas will benefit from migration because of climate change. Or maybe the Midwest should simply focus on investments to help their economies and create places people want to live….do the groundwork to encourage people to move to the region.

Poison Mushrooms: How to Tell – From the Natural History Society of Maryland…good pictures.

The Avenues of America – An overview picture of Washington DC taken from the International Space Station.

The Invasion Of The National Park System – Quagga mussels, Burmese pythons, feral swine, household pets gone wild, tamarisk trees….and those are just the ones pictured!

Pyramid made of dirt is world’s oldest known war memorial – Located in Syria…and at least 30 people – male and presumed to be warriors – buried in horizontal steps.

COVID-19 pandemic has been linked with six unhealthy eating behaviors -- ScienceDaily – Eating disorders are one of the deadliest psychiatric health concerns and 6 of them have a correlation to the pandemic: mindless eating and snacking, increased food consumption, generalized decrease in appetite or dietary intake, eating to cope, pandemic related reductions in dietary intake, and re-emergence or marked increase in eating disorders.

How flooded coal mines could heat homes – Evidently the water in the mines could be tapped as a source of geothermal heating/cooling!

Red Tides Under the Microscope | The Scientist Magazine® - It’s surprising what we don’t yet know about the organism responsible for red tides – Karenia Brevis. Spanish explorers of Florida in the 15th and 16th centuries described fish kills in Gulf waters. The first official documentation was in 1882 – published in the Proceedings of the US National Museum. This article is about what we know….and where more research is needed.

Offshore Wind Has the Potential to Fulfill Global Electricity Demand 18 Times Over - Yale E360 – Hurray for this potential….the transition is the challenge.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live.

Think everyone died young in ancient societies? Think again | Aeon Ideas – Even before the advent of modern medicine – there were people that lived to be very old. One of my great grandmothers lived into her 90s and all my grandparents survived their childhoods before vaccines. But many people didn’t. Epidemics like flu, typhoid, yellow fever and bubonic plague killed many people in the areas where they struck….but some people survived.

New battery could store wind and solar electricity affordably and at room temperature -- ScienceDaily – Lots of research on batteries and other forms of energy storage now….required if wind and solar power can supply 100% of our energy needs. I almost brought of ‘the grid’ but I’m not sure that a grid is going to dominate the future of our energy needs…it might…or might not.
