Gleanings of the Week Ending April 9, 2016

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.

Surgery, Stem Cells Treat Cataracts – Removing a cataract damaged lens but leaving the individuals lens epithelial stem cells (conventional cataract surgery removes them) allows the lens to regenerate. Initial results are good; if sustained this may be the new ‘conventional’ treatment for cataracts.

Man-made Earthquakes are on the rise, but they don’t have to be and As US Oil Production Increases, More Americans at Risk of Man-Made Quakes – Two articles about man-made earthquakes. The second one includes a map. Central Oklahoma has a risk of a damaging quake this year as high as the risk in California! Are the building codes in Oklahoma taking earthquakes into account? If they do, it is probably a recent update since earthquakes were not common in the state until recently.

Beware of Food Fraud – Olive oil is at the top of the ‘food fraud’ list evidently.

Streamer – USGS site that traces steams/rivers upstream and downstream. I you even wondered where the river near you comes from or goes --- this is an easy site to use. It map based so it is a simply as zooming to the river of interest and selecting upstream or downstream highlighting.

A Treasury of Prairie Wildflowers – This is a great time of year to get out and look for wildflowers no matter where you live. Even dandelions have their own charm (particularly if viewed with a magnifier).

6 Primary Transformative Paradigms for the Auto Industry – You’ve probably read about most of these in some form. I like collections like this that help me develop a framework for areas of technology (in this case ‘cars’).

Restoring the American Chestnut – Evidently there are blight resistant cultivars of American Chestnut but it is challenging to grow the 100s of seedlings for field trials and then restoration planting. This article is about experiments to optimize root production in the seedlings.

7 Citizen Science Projects for Bird Lovers – Another motivation to get outdoors this spring!

CDC expands range of Zika mosquito into parts of Northeast and Zika Attacked a Baby’s Brain as Doctors Watched – Scary stuff. I am already gearing up to walk around the yard and make sure we don’t have any standing water (and empty and refresh bird baths every other day). This is going to be a tough battle to keep the virus from spreading (and if it does keeping the mosquitos that carry it from continuing to spread it).

Successful dying: Researchers define the elements of a ‘good death’ – The themes culled from 32 studies were: preferences for a specific dying process, pain-free status, religiosity/spirituality, emotional well-being, life completion, treatment preferences, dignity, family, quality of life, relationship with the health care provider and "other." The bottom line is to ‘ask the patient.’ That seems to be common sense but how often is it actually asked by medical professionals and family member?

Natural History of a Place

2015 08 IMG_2303.jpg

I went to Belmont Manor and Historic Park in Elkridge, MD frequently enough over the past year to observe it in every season. Last summer a large English Elm on the front lawn of the Manor had to be cut down (Dutch Elm Disease). I took this picture shortly before it was cut down - the picture taken from an angle that the dead part of the tree didn’t show too much. A month later the tree was gone, the stump and exposed roots dug out, and new sod put over the wound. A month later and it was hard to tell where the tree had ever been. The episode stirred some thoughts about the natural history of a place and the significance of our actions on that.

The English Elm was planted – a non-native to North America. Whoever made the decision to plant an English Elm may have been wise in the end because this one lasted longer than most of the American Elms against Dutch Elm Disease.

The pond further down the hill was probably dug in the 1980s. It was probably always a wet area. There was probably a vernal pool there in spring. Lots of wood frogs would have successfully laid their eggs there and new frogs would have emerged. Now the pond has fish – that eat frog eggs.

In the 1900s – the area in front of the house was open. For some of those years it was pasture for horses. The forest would have been different. At the beginning of the century there might have been American Chestnuts in the forest. They would have been noticeable for their size and their nuts would have been gathered every fall – by people and squirrels (and other animals too). There is no tree that has quite filled the niche of the American Chestnut that was wiped out by the mid-1900s by the Chestnut Blight.

Earlier in the 1800s, many of the trees would have been cut for fuel. There were a lot of ironworks. There were massive erosion events when the forests were cut and the Patapsco River – downhill to the north of Belmont – received a lot of sediment changing it from a navigable river to a shallow, easily flooding river by the early part of the 1800s.

Prior to anything being built on the hilltop where the Manor House is today – the area was forested. The chestnuts were the big tree and the Europeans were impressed by the richness of the life in the rivers.

There is so much that we did not preserve…and that we still don’t quite know how to sustain.
