Salt Could Play a Role in Allergies | The Scientist Magazine® - Atopic dermatitis has increased more than 2-fold since the 1970s….and researchers do not attribute the increase to greater awareness or diagnosis. Now comes the observation that people with lesioned skin from atopic dermatitis (but not psoriasis) had a 30-fold higher salt level in their lesions than in their unlesioned skin or skin from healthy controls. The connection to diet is speculative at this point…but we do have higher salt in our diet now that most people had in the 1970s.

In Siberia, Toxic Black Snow Reveals the Toll of Coal Mining | Smart News | Smithsonian – Yuck! Pollutions from open-air coal pits…in the extreme.

Piling Up: How China’s Ban on Importing Waste Has Stalled Global Recycling - Yale E360 – China’s plastic imports have plummeted by 99%, mixed paper has dropped by a 33%. Recycled aluminum and glass are less affected by the ban. So now we are sending plastics to landfills, incinerators or littering the environment. Communities across the US have curtailed or halted their recycling programs. That hasn’t happened (yet) where I live in Maryland. We must learn to produce less recycle (waste) and process it more locally…not ship is someplace else in the world.

The people alive today are the stewards of the future Earth.

Ten Little Celebrations – February 2018

February 2018 has been busier than usual for me than in previous years since ‘graduation’ from my career (that does sound better than ‘retirement’!). The activity that caused that was the day long HoLLIE (Howard County Legacy Leadership Institute for the Environment) classes once a week. I celebrated 1) after the first one – realizing what a rich learning experience the institute was going to be – and after 2) after the second week when we are at Goddard learning about how and what satellites help us understand the Earth…and having the serendipity add on to the class seeing the big rock with dinosaur and early mammal tracks. I could have counted all 4 days as ‘celebrations’ but decided to choose some other items to add variety to this post.

20180208_073546.jpg

I celebrated seeing 3) 2 kinds of woodpeckers within about 10 minutes from my office window: pileated and downy and 4) the springtime tussling of male cardinals in the maple tree while the female looked on and stayed out of the way (a sign that winter in waning already).

The old crock pot being replaced by 5) an Instant Pot was a little celebration (because of immediate success using it) and continuing.

Usually I don’t find anything to celebrate in the news…but the 6) successful launch of the Falcon Heavy was something to celebrate. It’s great that there is a heavy lift capability available - a capability we need to further our exploration of space.

Several things came together this month – focusing my attention on how much I’ve enjoyed being a 7) Maryland Master Naturalist…I celebrated the 4-year journey.

I vicariously shared some of my daughter’s experiences this month – 8) celebrating her post doc – teaching – and ‘what next’ search. It’s invigorating to understand how full her life is --- how much we still share so easily.

The weather after mid-month has turned very mild here in Maryland. Earlier I celebrated 9) enough snow to be pretty and that I had 10) no commitments and could stay home on the day it turned icy.

HoLLIE – week 2

The second HoLLIE (Howard County Legacy Leadership for the Environment) class day was last week and it was held at NASA Goddard. I was worried about hitting rush hour traffic so left very early since we were to meet in the Goddard Visitor Center parking lot to catch the bus into the facility. The day was sunny and clear…but very cold and breezy. I managed to take this picture of the visitor center (not yet open) without getting out of my car!

20180208_073546.jpg

The theme for the day was “what informed citizens need to know about earth systems science.” It was the first of two days that our classes will be at Goddard; last week we started with lectures on “understanding the tools and the state of the art in earth science” from the Project Scientist for the AQUA satellite and then got a tour of mission control for several earth science satellites from the Aqua Mission Director. They did a good job of demonstrating the types of data that can be collected, the methods used to collect it, and the ways it has been analyzed. I was surprised to see the LRO (Lunar Reconnaissance Orbiter) mission control in the same building. That brought back the memory of my daughter being on the team to do image calibration shortly after it launched during her undergraduate days!

20180208_121831.jpg

On the way back to our classroom, we stopped by the replica of the big rock found at Goddard that has mammal and dinosaur and mammal tracks. This was not on our agenda originally but was a wonderful serendipity aspect to the day even if it took part of our lunch time. I’d read about it in one of my news feeds and followed the link to the paper…but it was such a thrill to see the exhibit and hear the short lecture. I managed to take a few pictures.

We started the lectures on ‘understanding the science of earth’s cycles’ that will continue in this week’s class. We talked about the oceans and the carbon system in this second class. One of the interesting videos in the lectures is available online: twenty years of global biosphere data mapped on a slowly spinning globe; it easy to see the annual cycles. With the massive amounts of data, visualization becomes an important component.

20180208_120511.jpg

When I got home an article in one of my newsfeeds talked about climate models that are developing that explain why there might be a linkage between melting of Arctic sea ice (one of the topics for the HoLLIE lectures this week) and droughts in California (How nuclear weapons research revealed new climate threats). It was easier to understand since I had the background of the lectures!

Why we still don’t understand sleep, and why it matters | Mosaic – Nacrolepsy…what has been discovered…but there is still happy ending for people with narcolepsy.

Photographer Captures the Beauty of Colorful Birds in a Series of Portraits – Pigeons, doves and cockatoos…what a trio!

(Some) Birds of the Pantanal – National Geographic Society – More birds. Couldn’t resist.

The History of Mincemeat Pies, from the Crusades to Christmas | Smart News | Smithsonian – A little history as we get closer to the winter holiday season.

Blood test can effectively rule out breast cancer, regardless of breast density: With over a 99 percent negative predictive value, a liquid biopsy test can help clinicians manage difficult-to-diagnose dense breast patients -- ScienceDaily – Hope this reduces the need for biopsies…and can be scheduled/processed more rapidly.

BBC - Future - An eco-friendly way to make smartphones – We have a long way to go to make smartphones in an eco-friendly way. The title of this article seemed hopeful but by the end, I was not sure that eco-friendly was motivating anything. Taking away China’s dominance of rare earth element production seemed the primary focus.

Transparent solar technology represents ‘wave of the future’ -- ScienceDaily – Wouldn’t it be nice?

Gleanings of the Week Ending September 23, 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.

Celebrate Cassini’s Historic Voyage in Eight Incredible Images | Smart News | Smithsonian – Cassini has crashed into Saturn’s atmosphere (intentionally) and there have been quite a few retrospective articles about its long mission. I liked this one…so am including in the gleanings for this week.

Eighteenth century nautical charts reveal coral loss -- ScienceDaily – The study compared the coral documented in the Florida Keys in nautical charts from the 1770s to satellite data. More than half the coral reef has disappeared completely. Nearer to land, the loss is closer to 90%.

What We Still Don’t Know about the Health Benefits of Nature – THE DIRT – I noticed this article first because the picture under the heading is of Klyde Warren Park in Dallas (I visited there several years ago and enjoyed it) but thin the article was worth looking at too. It defines some priorities for research to understand the health benefits of nature better although most people already agree that is it beneficial…but how exactly does it happen. Some doctors are already prescribing time in the park!

North American Ash on Brink of Extinction | The Scientist Magazine® - In Maryland many of the Ash Trees are already dead or dying. Very sad.

Top 25 Wild Bird Photographs of the Week #105 – National Geographic Society – There’s an Eastern Bluebird toward the middle of this collection….perched a little differently than I usually see them.

A Monumental Road Trip in Northern Arizona - National Parks Traveler – I’ve been to most of these places…..and enjoyed them all.

BBC - Future - How we’re creating ‘super plants’ to help humanity – The article highlights 4 ideas: cross-breeding super plants, using plants as medicine, bananas on steroids, and fire-fighting plants.

Learn How to Create Zentangle Art, a Meditative Form of Drawing – This article is about doing Zentangles (drawing patterns) rather than buying an adult coloring book. I started doing doodles and graduated to Zentangles and never was tempted by the ‘coloring book’ craze.

Ruins of a Roman City Found Off the Coast of Tunisia | Smart News | Smithsonian – The area of ancient Neapolis is off the coast of Tunisia. It was destroyed by a tsunami in 365 AD.

Why are fossilized hairs so rare? -- ScienceDaily – Evidently, fossilized hair is 5 times rarer than feathers.  Chemistry? Environmental conditions? The research includes statistical analysis of where hair and feathers have been found in the fossil record and make some predictions about where and how to look for them going forward.

Gleanings of the Week Ending August 26, 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.

Top 25 Wild Bird Photographs of the Week #101 and #102 – 50 bird pictures this week! My favorite in the first group is the barn owl (and the other owls in this group). My favorite in the second group are the two pictures of spotted owlets! --- I am drawn to owls this week for some reason.

Voyager: Inside the world’s greatest space mission – The two Voyager space craft were launched in 1977…and are both sending back messages to earth.

Trees with ‘crown shyness’ mysteriously avoid touching each other – I haven’t observed this phenomenon in our Maryland forests…but now when I am in a forest, I’ll always look for it!

Time Spent – Who Americans spend their time with (from Richard Watson’s blog). It changes with age. The last chart shows that as we get older we spend more and more time alone.

Air pollutions ranking in 32 cities –  LA ranks 24; Washington DC, San Francisco and New York are 26-28; Boston is 31. Delhi, Beijing, and Cairo are the top three.

Trees and shrubs offer new food crops to diversity the farm – Ongoing research from the University of Illinois trying to mimic the habitat features, carbon storage, and nutrient-holding capacities of a natural system with a farming method that incorporates berry and nut bearing shrubs/trees with alley cropping (hay or row crops)….to be economically and environmentally sound.

AWEA releases map of every wind farm and factory in America – There is a link to the interactive map. The red diamonds are manufactures and the blue dots are the wind farms themselves. It’s easy to see that manufactures happens a lot in areas other than where the wind farms are located….that the center of the country has a lot of installed wind turbines! We saw some of them in Iowa on our way to and from the solar eclipse last Monday.

Diversity Lacking in US Academia: Study – Under-representation of African Americans, Hispanics, and women in STEM faculties at public universities. There is a similar lack of diversity in PhD programs. On a positive note: the assistant professor is more diverse (more Asians, Hispanics and women) that the associate or full professor rank.  Unfortunately, this positive finding is not true for African Americans. Overall – still a challenge….and it impacts the broader labor market as well.

More than 300,000 Atlantic Salmon Spill into Pacific – Oh no! Hopefully this is not catastrophic in the long run. But – Why are they growing Atlantic salmon in pens in Puget Sound anyway?

Thanks to Co-op, Small Iowa Town Goes Big on Solar – Kalona, Iowa – not far from our route to the eclipse! It comes down to local self-reliance and economic development that made sense for this small town. Somehow a pointer to this article (from last February) was in a blog post I looked at when I returned home and I noticed where the town was…small world.
