How Tucson, Arizona is facing up to a 1,200-year drought – Harvesting rain!

The demented gift American politicians handed to China – About electric buses….and more. The suggested acronym by the author: GAGA (Give American Greatness Away).

New clues into a serious neurodegenerative disease – So many sources of cognitive decline….and we are just beginning to understand some of the mechanisms (and thus effective treatment). The research described in this post is about frontotemporal dementia.

World headed in wrong direction one 5 key mechanisms of climate progress – And the 5 are: share of unabated fossil gas in electricity generation, carbon intensity of global steel production, share of kilometers traveled in passenger cars, mangrove loss, agricultural production of GHG emissions.

Researchers reveal why shingles can lead to stroke - The risk of stroke is elevated for a year after having shingles. This study found that prothrombotic exosomes which can cause blood clots are found in those with shingles…and persist after the outward symptoms of shingles are gone. Using antiviral agents longer with the addition of antiplatelet and anti-inflammatory agents could help reduce the risk of stroke.

Will we ever…. live in city sized buildings? – Maybe. But would it be pleasant? Maybe an apocalyptic event would force us to do it to survive.

Vitamin D deficiency linked to premature death – The study evaluated 307,601 records from the UK Biobank. Take away message from the results: ensure that vulnerable and elderly maintain sufficient vitamin D levels throughout the year.

Omicron keeps finding new evolutionary tricks to outsmart our immunity – Variants within a variant!

Powerful Aerial Photos Show the Consequences of Drought on the Colorado River – The dry situation in the western US.

Cats react to ‘baby talk’ from their owners, but not strangers – And does this mean we are more than just a food provider in their world?

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 soil is a surprisingly noisy place – Wow! A whole new way of studying soil…listening to it.

Gas flares tied to premature deaths – A study done by Rice University environmental engineers with data from North Dakota and Texas. There are currently no limits to flaring, unfortunately. Why can’t we use the gas productively? It bothers me when we hear that we need more fossil fuels to observe the way the industry still is so wasteful and polluting.

Dying for makeup: Lead cosmetics poisoned 18th century European socialites in search of whiter skin – I had heard of lead makeup before…but never is this detail.

Top 25 birds of the week: forest birds – The only one of these that appears in the forest behind our house in Maryland is the Tufted Titmouse.

Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections – The labelling on foods fortified with Vitamin D does not say which type is used – hopefully it is D3. The supplemental Vitamin D I take is definitely D3.

The Prairie Ecologist – Photos of the Week – February 26, 2022 – Winter photography….it’s about over for us. Daffodils are up!

What is the best age to learn to read? – There is more variability that I realized…generally between 4 and 7. There is growing consensus that there is no reason to rush it. Learning language is key and often older children learn to read faster because their spoken language skills are greater.

Effects of noise on marine life – The study was focused on turtles and observed noise-induced hearing loss (sometimes temporarily) which hampers their ability to detect predators, communication, navigation, etc.

Rash-causing moths are spreading in Maine because of climate change – Browntail moths (native to Europe). I thought when I saw the headline that it might be about the saddleback caterpillar which is native to North America and has stinging spines that cause a painful rash. We had a specimen in the Brookside Gardens Wings of Fancy exhibit back in July/August 2018.

Study of algae in Acadia National Park lakes shows recovery from acidification – A success story…the Clean Air Act Amendments enacted in the 1900s are making a difference!

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.

New wearable device turns the body into a battery -- ScienceDaily – I’m always forgetting to charge my Fitbit until the low battery warning message comes up. It would be great to never need to charge it!

Soot from Asia travels express on a highway to the high Arctic : Research Highlights – Soot in the Arctic traced back to its source.

Working outdoors linked to lower risk of breast cancer among older women -- ScienceDaily - Outdoor workers are able to make more vitamin D which may be protective, say researchers. This is an observation…but might indicate a thread for future research.

World's first dinosaur preserved sitting on nest of eggs with fossilized babies – An fossilized Oviraptorosaur, a bird-like theropod, found on a nest filled with its 24 eggs.

Stealth Chemicals: A Call to Action on a Threat to Human Fertility - Yale E360 and Air pollution: The silent killer called PM 2.5 -- ScienceDaily – Products of human ingenuity that are negatively impacting our health.

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.

Was This Helmet Worn by an Ancient Greek Soldier During the Persian Wars? | Smart News | Smithsonian Magazine – Found by a dredging vessel off the coast of Haifa, Israel.

50 Birds: Adventures in Backyard Birding – Birding can be done anywhere. Many people have discovered the joy of bird watching from home during this pandemic year.

Joshua Trees: An Uncertain Future For A Mojave Desert Icon – A big fire and climate change….are the Joshua Trees doomed?

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.

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 Has Photography's Relationship With Nature Evolved Over the Past 200 Years? | Smart News | Smithsonian Magazine – A little history…that I used as a prompt to look for some of the works on Internet Archive. I’ll post about what I found for Kazumas Ogawa in a post next week.

Infographic: Deciphering Diet from Blood and Urine Samples | The Scientist Magazine® - Full article also available and more interesting that the infographic! The approach is still not perfected…but it may eventually help us get to personalized nutrition plans without as much trial and error that is required now.

Connection between gut bacteria and vitamin D levels -- ScienceDaily – Lots more needed to understand Vitamin D. This study indicated that blood tests for Vitamin D might not be useful at all since they don’t measure active Vitamin D….and active vitamin D is what correlates to gut bacteria…and potentially bone health. “Maybe it’s not how much vitamin D you supplement with, but how you encourage your body to use it.”

Get a Bird's-Eye View of UNESCO World Heritage Sites Across the Globe – Some beautiful places…from overhead.

How Non-Native Plants Are Contributing to a Global Insect Decline - Yale E360 – Insect declines….then birds. Lots of reasons to focus on planting natives a much as we can. I’m glad the forest behind my house is full of native trees and that I’ve replaced 2 bushs in the front of my house with natives. The challenge is to control the small but prolific invasive plants growing on the forest floor and into our yard enough for non-natives to survive. There used to be native jack-in-the-pulpits in our forest until several years ago.

How do we separate the factual from the possible? New research shows how our brain responds to both -- ScienceDaily – This article was frustrating. The study found that factual language is something our brains respond to. That’s not the issue at this moment in our nation’s history. The problem is the use of factual language about something not factual! Maybe this article is why we need to be more worried about public discourse/pronouncements.

It's One Hot Place Deep Down On The Floor Of Yellowstone Lake – About studies at Yellowstone Lake…the sensors and what they are revealing.

Shuttering fossil fuel power plants may cost less than expected -- ScienceDaily – Interesting…but I hope we’ll retire them all well before 2035 with the cost of renewals coming down so quickly. It will make economic sense to just do it!

Keeping Black Bears Wild And People Safe – This article is about black bears in Smokey Mountains National Park and the BearWise program more broadly. We do have Black Bears in Maryland and they occasionally show up in our area; there was one that showed up at our nearby elementary school a few years ago – caused a school lockdown until it wondered off.

Meet the Dipper, the Songbird That Swims – Evidently they are easier to spot in Colorado during the winter when they are concentrated long streams that remain unfrozen…but they are in the Rockies all year round…Dippers are elevation migrants (higher in the summer….lower in the winter). Maybe some post-pandemic trip we’ll look for them!

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.

Climate change presents new challenges for the drinking water supply -- ScienceDaily – Studying the Rappbode Reservoir in Germany and applying models….helping to predict what happens with warmer temperatures and increased drought…and what tweaks in reservoir management can mitigate.

The Lanterna of Genoa, the oldest lighthouse in Europe – The current Lighthouse of Genoa was built in 1543. The article includes some pictures of the technology used in the lighthouse from the 19th and 20th centuries.

Pollution and pandemics: A dangerous mix: Research finds that as one goes, so goes the other -- to a point -- ScienceDaily – Studying the relationship between along term ambient particles with a diameter of 2.5 micrometers or less and the spread of COVID-19….using air quality data and COVID-19 case across the country. There is a correlation – more pollution….higher COVID-19 transmission. Also: "We found black carbon acts as a kind of catalyst. When there is soot present, PM2.5 has more of an acute effect on lung health, and therefore on R0." This is an example of how air quality degradation has adverse health consequences.

Leila Jeffreys' Elegant Bird Portraits Show Feathery "High Society" and Photographer Tim Flach Captures Emotive Portraits of Fascinating Birds – I prefer birds in the wild…but sometimes portraits show the bird with more detail…certainly with less distraction. These two series were quite different but full photogenic birds.

Two centuries of Monarch butterflies show evolution of wing length -- ScienceDaily – Looking through museum collections and island populations of Monarchs, the researchers discovered how migration selects for longer, larger forewings….non-migrants have smaller wings! And they have determined that the effect is due to genetics rather than the rearing environment.

Photography In The National Parks: Birdy, Birdy In The Sky – Almost half the gleanings this week are about birds. I think this is my favorite. National Parks…great places for photography and birds add some action in the scene!

Top 25 birds of the week: Coastal birds – Some I’ve seen (particularly the ones in this group that were photographed in New Jersey). Others are totally new – like the Great Stone-curlew found in coastal areas of southern Asia…striking head pattern…and eye.

Tens of thousands of 12,000-year-old rock paintings found in Columbia – Found in an area previously inaccessible to researchers due to Columbia’s 50-year civil war. Made with red ocher.

Vitamin D regulates calcium in intestine differently than previously thought – Still new discoveries to be made about how our bodies work…how complex and interconnected the chemistry is….a system of systems.

Newly Discovered Underground Rivers Could Be Potential Solution for Hawai’i’s Drought – The potential for water wells off the coast of islands…supplementing fresh water available on the land to support the population living there.

Earth Matters - New Tools to Boost Access to NASA Earth Science Data – How NASA is using big data strategies to streamline processing time to get the information from satellites into usable form.

Trend of the Month… asocially| What's Next: Top Trends – Richard Watson noticing that some people prefer to be left along to look at their devices.

Image of The Day: Open-and-Shut Case | The Scientist Magazine® - They used box turtles in this research….a turtle we see here in Maryland relatively often.

Top 25 Wild Bird Photographs of the Week: Migratory Birds 2 – National Geographic Blog – Tis the season for bird migration!

BBC - Future - Should everyone be taking vitamin D? – It’s not clear cut. In the winter we probably don’t get enough Vitamin D from diet/sunlight…but the impact of that shortage is not obvious in many people. There are some trials that are ongoing that may provide some answers.

Why the Current Hurricane Rating System Needs to Be Scrapped - Yale E360 – Hurricanes are rated based on wind-spead….but storm surge and flooding for rain (coastal and inland) also causes damage. Hurricane Florence is an example of a Category 1 storm causing tremendous damage even though it wasn’t a ‘major’ hurricane.

Detailed maps of urban heat island effects in Washington, DC, and Baltimore | NOAA Climate.gov – Close to home for me since we live between Washington DC and Baltimore (not on either of the two maps).

Well-Preserved Murals Discovered in Pompeii - Archaeology Magazine – Finding new things in a site that has been studied for many years.

Surprising places where germs lurk in bathrooms | Berkeley Wellness – Hmmm…maybe we should add some tasks to cleaning the bathroom.

Nikon Small World photo competition reveals nature in minuscule detail | New Scientist – The beauty in the microscopic world. I want to look more closely at spittle bugs next spring…see if I can see the bug.
