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.

Macro Photos Highlight the Diverse Beauty of Butterfly Pupae – The pupae are Asian species….so no Monarch chrysalis (which is my favorite).

Good hydration linked to healthy aging – The findings don’t prove a causal effect…but hydration is linked to serum sodium…and chronic high serum sodium (i.e. when a person is dehydrated frequently) increases risk of developing chronic diseases like heart failure, stroke, atrial fibrillation and peripheral artery disease, etc.

The Infrastructure Sector Is Bleeding Workers – The workforce is aging…more are nearing retirement…and younger people are not coming into the jobs fast enough.

This new year – decarbonize your life – The beginning of a series about a family of 4…taking steps to dramatically reduce emissions and sequester carbon.

Gradient Arrangements of Food Highlights Biodiversity Not Often Seen in Supermarkets – Wow – what a range of colors and shapes in common fruits and veggies like: tomatoes, corn, potatoes, pears, peppers, squash, cucumber, kale, and beans.

Heat and cold as health hazards – Controlled experiments on how the body reacts to hot and cold…and the health consequences.

Water Worries: Threatened and Endangered Cultural Sites – Climate change has caused increasing severe rainstorms in the Southwest impacting the adobe walls  in Tumacácori National Historical Park in Arizona and Pecos National Historical Park in New Mexico. Storms, flooding and sea level rise are impacting other parks including Statue of Liberty National Monument, Colonial National Historical Park and the Jamestown Settlement, and Castillo de San Marcos National Monument. The tidal basin in Washington DC is crumbling as flooding increases as the Potomac River rises.

Researchers identify bird species depicted in ancient, finely detailed Egyptian painting – Click on the images to get a larger view of the birds. Key to the second image: a–f rock pigeons (Columba livia); g red-backed shrike (Lanius collurio); h white wagtail (Motacilla alba); i pied kingfisher (Ceryle rudis); j–l unidentified.

How microplastics are infiltrating the food you eat – Right now microplastics are viewed as a contaminant but research is revealing they may have harmful impacts….and should be studied and regulated as a pollutant. Will systems that use sludge as fertilizer need to change dramatically? It appears likely.

2022 Year in Review: Top Stories from Around the National Park System – Flooding at Yellowstone, Mauna Loa eruption, drought at Glen Canyon, maintenance challenges, invasive species …crowds…a lot of big stories.

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.

Why the Dutch embrace floating homes – Maybe other coastal areas around the world should be looking at this kind of development…or mitigation strategy. Otherwise - there is going to be a lot of migration away from coasts that will become more and more prone to flooding in the decades to come.

New Antarctic Penguin Colonies Discovered Further South than Normal – Good news for the Gentoo penguins - there is more space on Antarctica now; previously the areas were too icy for these birds. On the downside – there is less area suitable for penguin species that previously lived there and there might be less food available for them all as warming continues.

Three people with spinal-cord injuries regained control of their leg muscles – There has been a lot of research in this area over the past decade; perhaps we are coming to a point where rapid advances are going to be made.

Why to flickers knock on your house? – Not just why they knock but other interesting behavior…made me consider putting up a flicker box to give them a place to raise young.

Dog feces and urine could be harming nature reserves – A study providing rationale for requiring dogs on leashes and owners removing their dog’s feces in natural areas.

Top 25 birds of the week: February 2022 – My favorite this week is the Great White Pelican. Somehow pictures of birds from the front like this always give them a rather assertive appearance.

US household air conditioning use could exceed electric capacity in next decade due to climate change – Not good. Implementation of mitigation strategies need to ramp up quickly. As an individual homeowner, I am thinking: 1) increase efficiency (heat pump or geothermal, more insulation, solar screens on any window getting full sun sometime during the day, maybe upgrade windows/doors) and 2) solar panels on the roof with storage battery.

Threats from QAnon conspiracists force butterfly sanctuary to close – Sad. My husband and I visited the butterfly sanctuary on a rainy day during the Rio Grande Birding Festival in 2017; it wasn’t a good day for butterflies, but we always thought we’d come back on a warmer/sunnier day during some future visit to the area --- then the border wall and the conspiracists has ended it all.

More spice could help seniors avoid salt – Yes! Lemon pepper (the kind without salt in it) is one of my favorites…and any of the components that come under the heading of ‘Italian seasoning.’ I dry my own orange peel (any time I eat an organic orange…the peel gets processed and dried). It helps to use fresh ingredients too (i.e. avoid no-salt version from cans…they have never tasted good to me no matter how they are prepared).

Star Bright: What are Dark Sky Reserves? – Staunton River  (where we’ve been for ‘star parties’) is a Certified IDA International Dark Sky Park….maybe we’ll visit one of the Reserves post-pandemic. Right now – the closest one to us is the one in Canada (just north of Vermont/Maine).

National Park Service Publications on Internet Archive

/

Last September - I browsed 18 publications from the National Park Service that have been scanned and are freely available on Internet Archive. They are all decades old….reflect history of the places. The oldest one is from 1917 (The National Parks Portfolio) which is clearly a snapshot from the early years of National Parks. I was particularly interested in the “Astronomy and astrophysics national historic landmark theme study” published in 1989 – the year my daughter was born and she has grown up to be an astrophysicist! The only park I visited before the publication was Yosemite; the publication is from 1990 and I visited in 1984. I’ve provided a sample image for each volume. Enjoy some armchair traveling with some browsing via Internet Archive…find some correlations in the publications and your own life.

Wind Cave, 1979

Agate Fossil Beds National Monument, Nebraska, 1980

Astronomy and astrophysics national historic landmark theme study, 1989

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.

Well-Preserved Mosaic Floor Found in Roman Egypt - Archaeology Magazine – Lotus patterns!

Nations with strong women's rights likely to have better population health and faster growth-- ScienceDaily – A study analyzed databases which held information on health, human rights, and economic and social rights for 162 countries for the period 2004 to 2010.  The results suggest that gender equality is not just a women’s issue but a development issue.

More Climate Surprises Expected – THE DIRT – “Climate change together with environmental degradation and social and political instability is the threat multiplier.” It seems like more and more climate-linked surprises/disasters are happening every year. When do we reach a tipping point where everyone realizes that we cannot continue the status quo?

Liver transplants could be redundant with discovery of new liver cell -- ScienceDaily – From Kings’ College London. It would be a big step forward if this finding translates into standard treatment for liver failure.

Viking Woman Warrior May Have Been Slavic | Smart News | Smithsonian – Not all ‘Vikings’ were Nordic men…some were Slavic and some were women! It’s good to understand long ago cultures in more depth…particularly when it causes us to rethink our assumptions.

Top 25 Wild Bird Photographs of the Week: Birding – National Geographic Society Newsroom – Variety and beauty of birds…I always enjoy the ‘25’ collections.

How to keep buildings cool without air conditioning – according to an expert in sustainable design – We are going to need all the technology we know (and some new ones) to keep buildings and homes cool as the planet gets warmer.

America's packaged food supply is ultra-processed: Americans are overexposed to products that are high in calories, saturated fat, sugar and salt -- ScienceDaily – Unhealthy ‘food’ --- most of us have an inkling about this but it doesn’t keep us from indulging. The article mentions the Foodswitch app that allows consumers to scan packaged foods to determine their healthfulness; I loaded the app and scanned things in my pantry. The pasta I buy (whole wheat and green) rates a 5 of 5! Soymilk was 4.5. The canned tamales my husband likes are a 3 (salt and fat).

Thamugadi, a Roman outpost in Algeria, was saved by the Sahara – Buried in sand after it was abandoned around AD 700…and rediscovered in the 1700s but not explored. In the 1870s it was again rediscovered. It was excavated by the French from 1881 to 1960 in its entirety. It became a UNESCO World Heritage site in 1982.

100 days, 100 nights: Sensor network reveals telltale patterns in neighborhood air quality: Custom-built sensors deployed for 100 days and nights to track black carbon pollution -- ScienceDaily – A test was done in West Oakland with new technology to monitor air pollution with more specificity over the area and time of day(s) than has been done before now. The technology worked and demonstrated that the finer grain measurements provide deeper understanding of what impacts localized air quality…something we have to understand to make progress in improving city environments.
