Learning Log – March 2016

March was a huge month for classes...both online and traditional classroom/field work.

The 6 modules of Coursera’s Big History were a whirl wind discussion beginning with the Big Bang to the present and then initiating the importance of our understanding Big History as we contemplate our actions into the future. This is unlike any history course I’ve taken before in that it integrates a lot of disciplines rather than the traditional view of history. In Big History - wars and memorization of dates are way down on the scale of importance. Instead thinking about increases in complexity and energy flows are the drivers of change….and human history is in the context of the universe rather than insular to our species. I still have some references from the course to read/view but I was so fascinated by the material that I did all the lectures in March!

I finished 9 of the 11 modules of Coursera’s Soul Beliefs: Causes and Consequences Unit 2: Belief Systems. This is a continuation of Unit 1 which I finished in February. This part of the course is delving more into neuroscience and psychology. I’ve enjoyed it.

The Howard County Conservancy provided volunteer naturalist training for the spring field trips that will beginning in April for pre-school through middle school students. There was quite a range of topics: rocks, history of the places where we hike, insects, habitats, watersheds, literacy, seasons, and Bioblitz. In each of the 7 sessions, there was a classroom segment and then a hike to demonstrate the types of things we would do with the students. We looked at macroinvertebrates in the stream, learned to use iNaturalist, explored the hiking routes in detail, and sometimes pretended we were students. The first field trip is next Monday….so we’ll see how prepared we all are very soon!

Then there were all kinds of experiential learning going on – here are my top three for March:

Observing the effect of the combination of pine bark beetles, tree age, salt mist, and big storms at Chincoteague

Noting the large number of Tundra Swans at Eastern Neck National Wildlife Refuge and Snow Geese at Blackwater National Wildlife Refuge

Seeing two organisms I knew about from books and pictures but had not seen in the wild: the hemlock woolly anelgid (see previous post here) and a wood duck (more images coming in an upcoming post).

Gleanings of the Week Ending March 19, 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.

Eyeglasses that can focus themselves are on the way – I’m not sure whether this is the technology that will actually do it….but I sure would like glasses that adjusted to my needs rather than the static versions we have now.

Thickly Layered Paintings Literally Pop Off Artist’s Canvas – Bright and colorful….good paintings to pair with a spring day!

Down the Drain: Here’s why we should use rainwater to flush toilets – Good rationale but it seems like the retrofit for an existing house would be expensive. Our house had 3.5 bathrooms and they are not close together. The logistics of getting the collected rainwater to the toilets would take some design work.

Time to rethink your vegetable oil? – Research about what is good about linoleic acid. The study was funded by NIH (better than if it had been funded by lobbyists pushing grapeseed oil).

World Average Temperature Could Rise by 1.5 Degrees as Early as 2020 – This is close enough to be in the lifetime of the majority of us.

On-the-spot diagnosis of certain cancers and other diseases is closer to becoming a reality thanks to sensitive biosensor – If this technology is effective and done for a lot less cost than current methods (mammograms, colonoscopies, ultrasound, x-rays, biopsies, etc) – it will be quite a boon for patients. But will the vested interests of our medical system allow it to replace all that infrastructure in place for diagnosis?

An Interactive Timeline of the History of the Earth – A resource listed for the Big History Course I am taking. After landing on the page – click on the red triangle on the left of the screen and the timeline beginning with the Big Bang appears. Click and drag the triangle to the right and see more details on the progression along the timeline. When the triangle gets to 1 billion years ago, another bar will appear below with a new triangle on the left. Continue in this mode to the present. The page gets very busy!

Potential new therapeutic target for hypertension may offer less side effects – This therapy seems to be focusing on something closer to the ‘cause’ for age related hypertension which is very appealing. The more we understand about the body as a biological system, the more therapies will be of this type.

These 27 Solutions Could Help the U.S. Slash Food Waste – When I saw the picture of the food scraps at the top of the article – I realized how far I’ve come in the way I prepare food. Some of those green ‘scraps’ (stems and green leaves) looked good enough to go into a stir fry or soup! If everyone learned to use the produce they buy more completely – there would not be as much waste to deal with.

Facebooks is a growing and unstoppable digital graveyard – In 2012, 30 million users with Facebook accounts had died…some estimates claim that 8,000 users die each day. Just as Facebook has changed the meaning of ‘friend’ and ‘like’….it leaves digital legacy of its users.

Gleanings of the Week Ending March 12, 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.

Dragonfly is world-record flier – Confirmed by genetic analysis…this insect makes transoceanic flights.

Identity unearthed: How excavations in Sudan reveal the transformation Egyptian, Nubian culture – Cultural blending in the ancient world…with a lot of individual choice involved: Nubian bed or Egyptian coffin, wrapped like a mummy or not, Egyptian-type amulet or Nubian jewelry (or both).

Fitting into what I’m learning in my Big History class: Mysterious cosmic radio bursts found to repeat, Hubble breaks cosmic distant record: sees universe soon after big bang, and Einstein’s gravitational waves ‘seen’ from black holes – Every time I take a course, it seems like there are a lot of relevant articles coming out in the news feeds!

Astrobiology: Understanding Life in the Universe – Student companion site for the Charles S. Cockell text. Includes chart sets for each chapter – if all you want is an overview of the topic. The book is developed to support the Coursera Astrobiology course taught by the author (which I took last year).

Migrating Monarch Number Rebound – Hurray! The good news is from analysis of the numbers of butterflies at hibernation sites in Central Mexico. There were 3x more butterflies than the year before. Still – the area is still a lot lower than the 45 acres in 1996. The area was 10 acres in 2015, 2.79 in 2014, 1.66 in 2013. Outside of the hibernation sites – more people are planting or conserving milkweed which is needed for monarch survival and keeping that focus on increasing milkweed availability in the environment is what we in the US can do to help.

Toward diagnosing diseases such as cancer in their earliest stages – But can it be done very inexpensively? So far a lot of these diagnostic tests have added cost to the medical system and there a lot of people that are not going to have the disease (i.e. there is a lot of cost of lots of testing to find the few people that need treatment).

Can some birds be just as smart as apes? – Research with corvids (crows, jays and their kind) and parrots reveals that they are capable of thinking logically, of recognizing themselves in the mirror and of empathy. Even though the brain structures and size appear quite different…both birds and apes have a prefrontal brain structure that controls similar executive structures.

Irish Eyes Soda Bread – Something to bake for St. Patrick’s day – coming up on the 17^th.

Uncovering the Roman Roads Cutting Across England - An amateur archeologist using LIDAR…reveals roads the Roman’s build for trade and rapid deployment of troops (follow the ‘full story’ link at the bottom of the article to see a map).

Who Sleeps? – Sleep conserves energy and may be why so many species sleep…but there may be other benefits at all. This an article that summarizes our current understanding of sleep in some major types of organisms (marine mammals, birds, insects, and mentions ongoing research.

Gleanings of the Week Ending March 5, 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.

How Forest Loss is Leading to a Rise in Human Disease – Zika has been in the news lately – but there are other diseases associated with forest loss as well: malaria, dengue fever, Chikungunya, yellow fever, and Ebola. There is building evidence of how and why it happens.

New interactive guide tells the story of forest products in the South – Many years ago, I worked for St. Regis Paper in Texas before they were bought by International Paper – so I read this article with interest to see what has happened to the industry in the past 30 or so year. The guide is located here.

Invasive Plant to Avoid: English Ivy, Barberry, Butterfly Bush, Winter Creeper, Daylilies  - I liked these articles because they provided alternative to these invasive species to use in landscaping. I still have daylilies that I’ve had for years but I’m not going to be containing them rather than propagating them!

Spruce Tree House to Remain Closed at Mesa Verde National Park – Sad that this is closed. We probably have some very old slides from our vacation to Mesa Verde in the late 1970s that I should retrieve from storage!

Consumers have huge environmental impact – Thought provoking. The site for the EUs Glamurs project is here.

7 Resources for Natural History Nerds – Don’t let the initial picture stop you from looking at the rest of the article – it is only a lizard. These are impressive resources. I knew about only 2 of them before seeing the article. I’m bookmarking this article.

Getting the Word Out – More scientists are realizing that it is part of their job to get the interesting aspects of their work out to the public as part of modern instantaneous news. The public is demanding timely information on cutting-edge science!

Five Close Encounters of the Crocodilian Kind – The pictures are good….and the crocodilians are from around the world.

Lead, Plumbosolvency, and Phosphates in the Environment – A well written explanation of how water-works can go very wrong.

The Scale of the Universe – I’ve started taking a Big History course on Coursera and this one of the resources in the first week’s module. Scale is always a challenge and this site does a reasonable job in visualize the very small and the very large.
