Gleanings of the Week Ending December 5, 2020

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.
