Winter Day

On Saturday it was cold - but it was sunny, the snow was melting and there were robins on the roof of our deck taking sips of the melt from the gutter and shingles. It seemed like spring was on the way.

On Sunday, we were definitely a winter day and worse than most of our winter so far because it was more ice than snow. I decided to make the best of the return to winter by attempting some snow flake photography. The flakes were small - probably formed at lower temperature.

 

 

 

 

I used my loupe and took some pictures. Many of the flakes broke as they landed on the red glass plate (I had left it outside to cool down so they did not melt at all).

 

 

As the day proceeded the snow stopped and it rained instead…which led to ice buildup on all horizontal surfaces except for the birdbath (which is heated). 

The rain stayed liquid enough to wash away the salt that had been applied to our street proactively - and it froze before evening. The ice was not as smooth as an ice rink…but still very slippery. It’s an icy start to the work week. I am glad I don’t have to leave home!

Gleanings of the Week Ending February 28, 2015

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.

Pollinator Partnership Planting Guides - Planning a garden? How about giving the pollinators in your area a boost too? This site has a planting guide for ‘ecoregions’ in the US - accessed by entering your zipcode!

A Wet and Wild look Inside the 'Mushroom Houses' Of a Fungi Farm - Ever wonder how mushrooms you buy in the grocery store are grown? This post includes a short video. If we had household gardener robots - would you grow mushrooms as well as vegetables?

The Surprising, Depressing Reason Why City-Dwelling Robins Sing at Night - When I saw the picture at the front of this post, my first thought was “that’s not a robin.” But it is - a European robin. I was thinking of the North American variety. It is disturbing that our lights are messing up circadian rhythms - our own and other organisms.

What is the oldest city in the world? - It is surprisingly controversial. How many of the possibilities in the article have your heard about before?

Deconstructing mental illness through ultradian rhythms - A study that suggests that regular meals and early bedtimes may lead to a better life and prevent the onset of mental illness. The study discovered a new dopamine-based rhythm generator. The full paper is available here.

Retracing the roots of fungal symbioses - Mycorrhizal fungi live on the roots of host plants where they exchange sugars that plants produce for mineral nutrients that fungi absorb from the soil. It is hard to visualize - and often not well understood. Now genomics is being applied. Climate change will put whole new stresses on symbiotic relationships. I hope the knowledge gained from this type of research will help us maintain or increase food production as the environment changes.

Liquid Biopsy - Fast DNA-sequencing machines are leading to simple blood tests for cancer - There are some technologies that are so appealing…that you wish they were already available. But it is not easy. So far - the work is for specific types of cancers. The ability to do faster DNA sequencing is improving the prospects.

Ocean circulation change: Sea level spiked for two years along Northeastern North America - Climate change and the Atlantic Meridional Overturning Circulation (AMOC)…most of the models predict a weakening of the AMOC over the 21st century and it appears that there was changed in the 2009-2010 time frame.

Computational Anthropology Reveals How the Most Important People in History Vary by Culture - This study looked at articles about significant people in the English, German, Chinese and Japanese language versions of Wikipedia as a data source.

These Brilliantly Colored Bolivian Buildings Look Like Alien Spaceships - Wow! Almost too much color…but certainly different than the majority of buidlings.
