Gleanings of the Week Ending July 1, 2017

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.

Carbon in Atmosphere is Rising, Even as Emissions Stabilize – Are the carbon sinks less able to function as CO2 levels have risen? Still TBD. There is still a lot to understand about our planet and the impact of higher and higher greenhouse gases in the atmosphere.

Cats Domesticated Themselves, Ancient DNA Shows – Cat came into settlements on their own…enjoying the bounty of rodents human settlements contained. They didn’t give up their wild natures to the extent that dogs and other domesticated animals did. There is genetic evidence that they’ve remained largely unchanged for 1000s of years.

Not so pearly whites – Evidence of a filled dental cavity in a 13,000 year old hunter-gather tooth!

43 Incredible Photos of US UNESCO Sites: Present and Proposed – I was surprised that I had visited so many of these places (the ones in the continental US).

Plastic Pollutants Pervade Water and Land  and Microplastics sloughed from synthetic fabrics in the washing machine - Plastics are everywhere in our environment and their  negative impact is probably greater than we realize…but it is surprising how much we don’t know.

In the AI Age, being ‘Smart’ Will Mean Something Completely Different – The author proposes that the new definition of ‘smart’ will be about the quality of thinking, listening, relating, collaboration, and learning…not about the quantity of factoids we remember. It won’t be easy to be the new kind of smart and I often wonder if the way we use current technology has moved us in the opposite direction.

American Icon in the Alaskan Horizon – Birds at the Chilkat Bald Eagle Preserve in Alaska…in snow and ice.

11 Very Different Types of Photography that Each Illuminate Our World – A little eye candy for the week…and a survey of types of photography.

Mars rover Opportunity on walkabout near rim – One of my daughter’s first jobs as an undergraduate student was calibrating images coming from Opportunity…so I always take note when articles come out of it.

Mapping the potential climate effects of climate change – I look at these types of articles and try to understand the assumptions that are being made. It always seems that there are still a lot of unknowns….and it could be different and worse than they projections. Basically north and west seem to fare better than the south where it is already hot and often dry.

Our Neighborhood Water Retention Pond

The water retention pond that is supposed to slow down water run-off from our neighborhood was not working and there was flooding occurring with more frequency. Earth moving equipment was brought in by the country and turned a pond with lots of vegetation for wildlife around it (picture from last December)

Into a mud pit with very little vegetation around it. We had a day of heavy rain right after the vegetation was scraped away and the water than accumulated looks thick with silt and has already developed a green scum.

Here it is from a different angle. No one will be sitting on the bench enjoying the antics of red winged blackbirds in the cattails or frogs crocking in the pond anytime soon! One of the neighbors commented that she’d seen a large owl looking at the pond from one of the neighboring houses. It’s likely that it’s home was destroyed. Hopefully, the project will enable the pond to function as it should for water retention. The pond needs some grasses or other vegetation planted on the slopes or this clean out of the pond is going to be short lived.

The only positive thing I saw on my walk around the pond was a single solitary sandpiper. With the heavy vegetation that was around the pond previously, the bird would not have been visible even if it had visited.

On the back side of the pond there is milkweed coming up but the plants are on the edge of the area not previously mowed. Hopefully they will survive for the Monarch Butterflies this season.

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.

The Creamy, Sculpted Dunes of White Sands National Monument – I’ve only been there once…but it was memorable. It was a hot day but the sand is so white that it reflects the sun and can be walked on barefoot! (See my post from back in June 2013 here)

Tracking down water pollution through DNA of algae – A new method for rapid and reliable bioassessment of aquatic environments which will allow for synchronous processing of many samples in record time and reduced cost….no more microscopic identification of organisms in samples!

Circadian Rhythms Influence Treatment Effects – There is a lot of evidence that timing of a medication may have a marked impact on effectiveness….yet drug trails did not track time of day information and thus not on drug labels. Simultaneously – understanding a patient’s circadian rhythm is an aspect of precision medicine - find the right drug for the patient at the right dose… administered at the right time. Also see the infographic: Circadian clock affects heart and disease

How Western Civilization could collapse – Doom and gloom scenarios. Do they seem more likely than they have in recent decades?

What’s chemistry ever done for us? – In infographic from Compound Interest that came out prior to the March for Science last weekend.

Incredible photos of Japan’s natural landscape that look like watercolors – Eye candy….and a little geography too.

4 great things the EPA had done for our health – A lot of progress has been made since 1970 when the EPA was created. No one should want to go back to air so filled with smog that your eyes watered when you went outside (like happened in LA) or lakes became sterile from changing pH or rivers caught on fire.

Foreignceuticals: our drugs go global – Scary. It’s often hard to tell where drugs and supplements come from….and there may be little or no quality control along the way.

Climate change is turning dehydration into a deadly epidemic – More very hot days….drinking soft drinks rather than contaminated water to rehydrate…maybe some other factors  - kidney disease rise dramatical in laborers in Latin America.

5 Ways to Prevent Food Waste in Your Kitchen – Probably nothing new here but always worth a quick check…ratcheting up what you do to avoid wasting food.

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 tale of four skulls: what human bones reveal about cities – History from a different perspective!

I spent a week exploring how we’ll have to live in a post-water America – We often take water for granted – turn on the faucet and it comes out. This article was about taking a different perspective and might be a shift in thinking we’ll be required to make in the future.

New map highlights bee population declines across the US – Not good. The declines are occurring in key agricultural regions.

10 Must-see Sites of Iran’s Historical Architecture – There are 20 UNESO World Heritage Sites in Iran. Too bad that part of the world is not a safer travel destination. Enjoy the pictures!

Our Water on Drugs – Treatment of water started out focused on sewage…then expanded to include nitrogen and phosphorous. Now the residues of drugs and personal care products are becoming a concern.

Popular heartburn drugs linked to gradual yet ‘silent’ kidney damage – Proton pump inhibitors (like Prevacid, Prilosec, Nexium and Protonix) taken over prolonged periods can have significant risks.

Cocoa, Caffeinated ‘Black Drink’ was Widespread in Pre-Contact Southwest – A ‘caffeine trade network’ brought cocoa and yaupon holly to the southwest….and the residue from the drinks are found in pottery. One of the first analyzed was from Chaco Canyon!

The Country’s Most Famous Bald Eagle Pair Just Laid Another Egg – The Bald Eagles at the US National Arboretum are keeping 2 eggs warm! See them on the nest cam.

6,600 spills from fracking in just four states – Drilling down on the stats – 26% in Colorado and 53% in North Dakota occur at wells that experienced more than one spill…the industry should be using this data reduce the risks of additional spills.

New Discoveries from Cahokia’s ‘Beaded Burial’ May Rewrite Story of Ancient American City – Some of the ‘men’ buried in an elite grave excavated in 1967 were women based on a new evaluation of the skeletons!
