Gleanings of the Week Ending May 11, 2024

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.

A new way to quantify climate change impacts: 'Outdoor days' - Noting the number of days per year that outdoor temperatures are comfortable enough for normal outdoor activities. In the North, in a place like Russia or Canada, you gain a significant number of outdoor days. And when you go south to places like Bangladesh or Sudan, it's bad news. You get significantly fewer outdoor days.

Is filtered water healthier than tap water? - Water filters, it seems, are having a heyday – particularly in North America, Europe, and China. I was a little surprised that the article did not mention microplastics in water – even in countries that have relatively high standards for their water supplies.

Baltimore’s Toxic Legacies Have Reached a Breaking Point – “Normal” southwest of the collapsed Frances Scott Key Bridge in Baltimore…one of the most polluted places in the U.S. – a different perspective on the bridge collapse.

European ruling linking climate change to human rights could be a game changer — here’s how - On 9 April, the European Court of Human Rights delivered a groundbreaking ruling: states are obliged to protect their citizens from the threats and harms of climate change. And in that regard, judges said, Switzerland’s climate action has been inadequate. Without prescribing specific years or percentage reductions, the ruling set out how a nation can show it is compliant. It must set out a timetable and targets for achieving carbon neutrality, and pathways and interim targets for reducing greenhouse-gas emissions. Measures must be implemented in a timely, appropriate, and consistent manner. Governments must also provide evidence that they have complied with targets, and update targets regularly.

Positive perceptions of solar projects - A new survey has found that for U.S. residents living within three miles of a large-scale solar development, positive attitudes outnumbered negative attitudes by almost a 3-to-1 margin.

18th-Century Foundation Uncovered at Colonial Williamsburg – Even in much studied areas, there are still new things to discover!

Metabolic health before vaccination determines effectiveness of anti-flu response - Metabolic health (normal blood pressure, blood sugar and cholesterol levels, among other factors) influences the effectiveness of influenza vaccinations….even in people with obesity which the vaccine had previously been documented as being less effective.

The environmental cost of China's addiction to cement - Today, China still accounts for just over half of the world's total annual 4.1bn tons of cement production (52%) – followed by India (6.2%), the EU (5.3%) and the US (1.9%). Little of that cement produced in China is exported. In 2020 the country used an estimated 2.4 billion tons of cement, 23 times the amount used in the US in the same year.

Teotihuacan's Pyramids Damaged by Ancient Earthquakes – Damage from megathrust earthquakes at the site between about AD 100 and 600: fracturing and dislodging of large masonry blocks used to construct the buildings, as well as chipping of blocks that comprised the pyramids' outer stairs.

Mini-colons revolutionize colorectal cancer research - Scientists have combined microfabrication and tissue engineering techniques to develop miniature colon tissues that can simulate the complex process of tumorigenesis outside the body with high fidelity, giving rise to tumors that closely resemble those found in vivo….offering a new path to research colon cancers and their treatment.

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.

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).

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.

Alexander Calder – Modern from the Start – An exhibit at The Museum of Modern Art (MoMA). There are pictures and a videos of the exhibit on the site. I watched the webinar on the 25th  when it was live and am in the process of looking at the rest of the site now.

Doug Tallamy’s List of Best Plant Genera for Supporting Moths and Butterflies | pollinator-pathway – Arbor Day is coming up in most areas (it varies by state depending on the best tree planting time. If you are thinking about planting a tree (or trees), think native and ones that support moths and butterflies!

Top 25 birds of the week: Bird Colours! - Wild Bird Revolution and Top 25 birds of the week: Bird Communication! - Wild Bird Revolution – Enjoy a double dose of bird photographs this week.

New skin patch brings us closer to wearable, all-in-one health monitor -- ScienceDaily – Still in the research phase…but a step forward. I like the idea of a blood pressure measurement that can be linked with other data throughout the day.

Is the Western way of raising kids weird? - BBC Future – We tend to think that the cultural norms we grow up in are the ‘best’ – but that may not always be true.

On U.S. East Coast, Has Offshore Wind’s Moment Finally Arrived? - Yale E360 – Reliable source of wind and proximity to populous markets….maybe the false starts are finally in the past for this renewal source of energy.

10 virtual tours of spectacular buildings around the world | Top 10s | The Guardian – More places to visit virtually!

Slideshow: Watch Insects in Motion | The Scientist Magazine® - Some technologies researchers are applying to better understand how insects have become such successful fliers.

How the Loss of Soil Is Sacrificing America’s Natural Heritage - Yale E360 – At best 24% of Corn Belt topsoil is gone…at worst 46%....and topsoil is still being lost. The study found that the main source of erosion is not water runoff but tillage…and right now only 15% of acreage in the heart of the Corn Belt is ‘no-till.’

Oldest Known Wild Bird Hatches Chick at Age 70 | Smart News | Smithsonian Magazine – Wisdom, an Laysan albatross, returns to Midway Atoll again. Her chick for this year hatched on February 1. She has outlived the person that originally banded her!

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.

Go Orchids: North American Orchid Conservation Center – A great site for learning about orchids…mentioned in my second post about the class I attended at the Smithsonian Environmental Research Center.

In praise of drawing - The Painters Keys – This is post originally written in 2006 but still very applicable today. I looked more at Internet Archive for some of the ‘how to draw’ books that were mentioned in the article; it’s amazing that in a 40-year period in the 1800s so many were published. A more recent post – from a science education perspective – was published in 2015: Rediscovering the forgotten benefits of drawing. I am contemplating taking a ‘next step’ from Zentangles to realistic drawings.

Time-Lapse Videos Capture Echinopsis Cacti in Bloom – Eye candy videos…beautiful.

Free Technology for Teachers: 7 TED-Ed Food Science Lessons – We could all learn a little more about the food we consume….educate ourselves to eat wisely.

Research Dollars Go Farther at Less-Prestigious Institutions: Study | The Scientist Magazine® - Interesting finding. I wonder if it will change how some organizations that award research dollars make decisions in the future.

Material formed from crab shells and trees could replace flexible plastic packaging -- ScienceDaily – This type of technology gives me hope. Recycling can’t do everything. We have to reduce the non-compostable materials in our packaging…have a net decrease in what has to be (expensively) recycled and/or go to the landfill.

Recovery: America’s Giant Squirrel Back from the Brink – Cool Green Science – I’ve seen signs about the Delmarva Fox Squirrel when we have gone to Blackwater National Wildlife Refuge but have never seen one. It’s good to hear a environmental improvement story!

As usual – I can’t resist the ’25 birds’ posts from National Geographic. Here are two that have come out recently: Top 25 Bird Interactions and Top 25: Wild Birds with Spectacular Catches

BBC - Future - The complicated truth about a cat’s purr – We all like to think that when our cat purrs that it is a sound of happiness…but is it?

Compound Interest - Volcanic eruptions: the chemistry of lava and volcanic gases and Compound Interest - The chemistry of spinach: the iron myth and ‘spinach teeth’ – Two posts from Andy Brunning. In the first one – click on the graphic and the larger version of the infographic will appear....a timely post with the volcanic event in Hawaii this summer.
