Gleanings of the Week Ending June 18, 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 dirty is your air? – Based on this article – I am trying to get in the habit of turning on the vent fan when I am cooking….and opening some windows when the outdoors temperature is pleasant.

Serious Putty – A clay with antimicrobial properties…even against resistant strains! More research is needed – but it is exciting that this could be a totally different mechanism for fighting infection that the current antibiotics on the market.

Snow in Vietnam and Other New Climate Patterns Threaten Farmers – This is from the Business Report section of the MIT Technology Review. The article focuses on farmers in Vietnam in an area that got snow for the first time in their life time (and historically) last winter and how weather patterns are impacting their finally honed rhythm for crops. It would be interesting to hear stories from farmers around the world. Climate is changing globally – but not always in the same way.

Sunflower Spirals: Complexity Beyond the Fibonacci Sequence – The results of a crowd sourced look at sunflower spirals: 1 in 5 did not conform to the Fibonacci Sequence. Some of those non-conformers approximated it and others approximated more complex mathematical patterns! Either way – I like the look of sunflower spirals.

Genome Digest – Recent findings of genomic research on giraffes – carrots – zebrafish and gar – herring – Atlantic salmon. A lot has changed since I got my biology degree in the 1980s.

Seeing the Inevitable, companies begin to adapt to climate change – Most companies are aware that climate change is likely to affect their future but are not planning for it with any consistency or depth. Those furthest along are those already dealing with climate change on a daily basis: agriculture and insurance. Ikea and Ford are two companies used as examples in the article.

Tranquil Impressionist-Style Paintings Showcase Beauty of Natural Parks Around America – Eye candy for the week!

Life in the Dark – Photographs of sea and cave creatures that live their whole lives in the dark.

C40’s Executive Director Mark Watts on how mayors are changing the way we think about food – Area of focus are food: procurement, production, distribution, and waste.

Frog, Turtle Species Being Reintroduced to Yosemite Valley – The California red-legged frog (the largest native frog in the western US) and the western pond turtle are being reintroduced to lake, river and meadow habitats.

New Climate Spiral – A visualizing of average global temperatures. Do this little exercise with the graphic – if you live to be 100, how much hotter will the planet be than when you were born? For me – it is about 2 degrees…almost 3 degrees hotter than in 1850.

Climate change poses threat to World Heritage sites - Melting glaciers, rising seas, increasing wildfires and harsher droughts….these could diminish the value of protected sites and even make them unsuitable for World Heritage designation. That would have a domino effect into local economic development, in particular the tourism sector.

Bionic leaf turns sunlight into liquid fuel – And at a higher efficiency than the fastest-growing plants!

Washington grapples with a thorny question: What is a GMO anyway?  and Report: Still lots to learn about GE Crops – The terms GMO and GE are inadequate to describe the complexity of what is happening now. Both of the articles are about a recently released report on the situation.

What’s up with microbeads – Plastic microbeads cause long term health effects in our waterways (streams, rivers, lakes, oceans). There are US regulations that are being phased in over the next few years to require that manufactures no longer make products with microbeads but prior to that individual can stop purchasing the products. I’m going to check packaging to avoid products with microbeads; the key ‘ingredients’ to avoid are polyethylene, acrylate copolymer, and polypropylene.

Top 25 informative maps that teach us something uniquely different about the world – Displaying data by location makes for easy comparison. If you did not already know about the US and paid maternity leave – the map makes if very clear – not something to be proud of.

Teenage brain on social media – It’s always been true that teenagers are better at doing than not doing (i.e. inhibition develops more slowly than other forms of cognition). This study was about how that translates into the social media realm.

Antibiotics from scratch – Drug resistant bacteria are becoming more and more problematic. This research is a ‘bright spot’ in developing antibiotics to stay ahead. No one wants to go back to the time before antibiotics.

Arctic Foxes ‘grow’ their own gardens – From Alaska’s Arctic National Wildlife Refuge.

Image of the day: don’t eat me – Usually moths are rather drab – not this tiger moth!

6th Graders at Storm Water Engineering

Last week I volunteered during a 6^th grade field trip to Belmont Manor and Historic Park. It was the last of the Middle School spring field trips there. The field trips activity were a mixture of history, technology, and science. My station for one of the day was about storm water engineering. The majority of the students realized that Belmont is on a hill and that the rain water would run downhill to the Patapsco River into Baltimore Harbor then to the Chesapeake Bay and then the Atlantic Ocean. Each team of 4-5 students was given a paint tray with a mound of earth at the high end of the tray as a model for what happens to storm water. They could add sticks, stones, and dry grass in any way they wanted to slow the flow of the water when it ‘rained’ (via a watering jug) on the soil. After 10 minutes of engineering by all the teams, the teams did a short description to the whole group and then the ‘rain’ came as everyone watched.

A surprising number of teams did not think to cover the soil at the top of the tray. It ‘eroded’ when the rain came down and often resulted in fast water runoff and the water was muddy too.

Some of the teams did cover the soil and used rocks and sticks to hold grass in place both over the soil and rocks; the grass turned out to be very absorbent. The water took a long time to get through to the bottom of the paint tray….and was generally clear.

As I watched the teams decide what they were going to do, implement their design, present their design, and then test it, I was intrigued by the ‘light bulb’ moments of learning that were visibly occurring all along the process.

As I walked back to my car after the last field trip – I took a picture of the bald cypress down near the pond – the tall grasses waving in the misty day…. feeling happy to have been a part of the field trips for middle schoolers at Belmont.

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.

Exposure to chemicals in plastic and fungicides may irreversibly weaken children’s teeth – Another reason to pay close attention to Bisphenol A (BPA) and Vinclozolin in diets of children. Based on this study – this is not something that fluoride treatments or supplements would overcome.

Identifying Wildflowers: part one, part two, part three, part four – From Elizabeth’s Wildflower Blog. This series include a lot of practical advice for identifying wildflowers in the field (and confirming after you get home). I’ve been following Elizabeth’s blog since I was in Master Naturalist class with her --- learning about wildflowers.

Language of Women versus men – An analysis of language in Facebook messages shows that women use language that is warmer and more agreeable than men. The graphic associated with the study is worth a look.

Mysterious Cave Rings show Neanderthals liked to build – And more than 1,000 feet into the cave where it would have been very dark.

Kazakhstan’s treasure trove of wildly-flavored apples – Forests where apple trees are the predominant species!

Tidal Troubles in the Mid-Atlantic – A place where the sea level is rising at a much faster rate than almost anywhere in the US (except parts of Louisiana and South Florida)…and an explanation that goes back to the last ice age which left the area with a ‘fore-bulge’ – so the land is sinking from that then the ocean is rising too! The net is a predicted sea level rise of 3 feet around much of the Mid-Atlantic by 2100.

Three perfectly blue days at Crater Lake National Park – I haven’t been to this national park – yet. This is an article to look at again when I finally get around to planning the trip.

Swarms of Octopus are taking over the oceans – Cephalopods as ‘weeds of the sea’!

The Cactus Smuggler: Are Desert Plants Being Loved to Extinction? – Not a good trend and very difficult to change.

Low-salt diets may not be beneficial after all – Evidently the prior recommendation for low-salt diets was not based on data – the old recommendation was ‘popular thought’ rather than based on objective evidence! High-salt is still bad….but average (between 3 and 4 grams per day) is best!

Arecibo in 1978

I saw a story about a large radio telescope being built in China recently and it reminded me of the one in Puerto Rico – Arecibo. My husband was there in September 1978 – just a few months after he went to Wallops and Chincoteague. It was all part of his first years as a graduate student. The trip he made to Arecibo was the longest travel-for-work either of us ever did and we were a little discombobulated by it; looking back I wonder why I didn’t take the opportunity to take some vacation and see Puerto Rico; I suppose that we were so unsure of our financial situation that we didn’t even think about it. He brought back a lot of photographs of the place. Look closely at this first picture and note the people on the structure (upper left) and in a small enclosure evidently hoisted to allow work on the structure (center).

There are some pictures of 1978 vintage computers.

Then the view looking down to the dish at an angle

And to the very center.

Underneath the vegetation is kept at bay.

At that time – I had never seen variegated croton. My husband brought back pictures and some dried leaves as a souvenir.

Hawai’I at the Energy Crossroads – A case study about the issues with how we produce electricity – now and into the future.

“Top tips for men juggling a successful career and fatherhood” hilariously nails how sexist the advice given to working women is – For anyone that doubts that gender bias is still quiet prevalent in the workplace.

Ancient tsunami evidence on Mars reveals life potential – Evidence of cold, salty oceans on Mars (the image of Mars was produced using Google Earth!)

Restoring an Ancient Nursery for Atlantic Sturgeon – These fish can reach 14 feet in length and weigh 800s pounds – a species that has been around since the dinosaurs. In the 1890s, caviar from Delaware River sturgeon was a thriving enterprise. Within a decade, the population of sturgeon fell to 1% of its historic numbers. Even with a moratorium on sturgeon fishing in the 1990s, the fish were not recovering due to ship strikes, channel dredging, and poor water quality. Now – with focus on dissolved oxygen, salinity, and flow conditions….and understanding the extent of spawning and nursery habitat in the freshwater portion of the river…slow recovery is beginning.

Antibiotics that kill gut bacteria also stop growth of new brain cells – Another reason antibiotics should not be overprescribed….and that we look for ways to resolve an infection that does not kill gut bacteria.

Wildlife is where you find it – A reminder that the natural world often survives even in a very man-made environment…and to be observant enough to notice it.

Bright light alters metabolism – Blue-enriched light in the evening seems to be problematic….will electronic devices of the future modify the type of light they emit based on time of day to help us stay healthy?

State of North America’s Birds Report Released to Commemorate Centennial of the First Migratory Bird Treaty – Birds connect our continent and some progress has been made. There is still a lot to be done. Individual actions like choosing sustainably created products, preventing bird collisions with windows of our houses and office buildings, and participating in bird related Citizen Science project (like eBird) make a difference.

10 Overlooked Wildlife Experiences in our National Parks – Sometimes small creatures that make their homes in National Parks are just as memorable as the scenery.

Toothpaste Tips and Myths – Toothpaste comes in lots of different formulations. Educate yourself about the good – and not so good – aspects of some of the benefit claims.

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.

Maryland climate and health report identifies state's vulnerabilities to climate change – Extreme weather, increased risk of foodborne illnesses, health impacts of extreme heat (hear attacks, asthma), increased accident risk from extreme precipitation.

Why vultures matter and what we lose if they’re gone – We have black and turkey vultures in our area of Maryland. I see them frequently and appreciate their place in the ecosystem – cleaning up carrion. Without vultures – other scavenger populations grow, often with negative consequences for human health.

Night Vision Problems and Driving – Something else that happens to most of us as we get older. I was surprised that the article did not mention astigmatism as more problematic at night if it is not corrected. I always notice my glasses not being quite right at night before I do in the daytime and it is usually the astigmatism correction that needs adjustment.

Colorful Watercolor Paintings of Radiant Trees in Nature – I couldn’t resist some eye-candy for this collection of gleanings since so many of the other items seem so serious.

New Zika Diagnostic – I’m glad they are making progress at diagnostics…now we have to make progress on prevention too since having a lot of infected people is going to be a public health crisis.

Test Your Sleep Smarts – How many of these did you know? The explanations of the answers are included…and sometimes contain links to more detailed information.

Team highlights ways to address global food challenges – Agriculture produces enough calories to meet basic human dietary needs worldwide…but one out of eight people in the world do not have access to sufficient food. This study presents a set of strategies to overcoming the challenges of providing food for the global population.

How Rising CO2 Levels May Contribute to Die-Off of Bees – Evidently an increase in CO2 often causes a decrease in the nutritional value of plants. A detailed study of golden rod pollen showed that pollen from plants in 2014 contained 30% less protein than pollen from 1842 (with the greatest drop occurring between 1960 and 2014). That’s important to bees that depend on goldenrod pollen for late season food. It’s important to us because nutritional value of crops like wheat and rice are similarly impacted by higher CO2 concentrations.

Too much folate in pregnant women increases risk for autism, study suggests – Another case where too much of a good thing is not good. A lot of the nutritional information is about minimal requirements. Supplements make it possible to get much higher doses than the minimal requirement. There appears to be a correlation with very high level of folate right after giving birth and the risk of autism spectrum disorder.

Meet the Bee Expert who Helped Invent the BioBlitz – I noticed this article just as we were finishing up the Belmont BioBlitz this week….and decided to include it in this week’s gleanings.

Four Days of Belmont Bioblitz

I spent Monday through Thursday of this week at the Belmont Bioblitz. Fifth grade students from 2 elementary schools participated on Monday and Tuesday; on Wednesday and Thursday it was seventh graders from a middle school. The observations the students logged into the iNaturalist app will be used to refine the Belmont Species List; the list originated from previous Bioblitz events at Belmont. All four days started our similarly – the volunteers gathering in the morning to help the staff prepare. It was quiet enough for some birds (like the nuthatch below) to be at the feeders near the nature center; the feeders would get refilled before the students arrived.

The volunteers would gather in a long line across the drive from the Manor House where the buses would eventually pull up.

Turning around - the swallows and red-winged black birds swooped over the grasses and down to the pond. The volunteers enjoyed the past bit of calm.

And then the buses arrive – almost hidden by the trees as they first come through the entrance gate.

Then more visible as they get closer. The students pour out of the buses and into groups - each with a chaperone (or 2) and 2 volunteers. The volunteers have been assigned zones where their group will focus for the duration of the morning.

Trees are easy to document although the blooms of the horse chestnut were already fading by Monday.

The leaves still were distinctive enough to make identification easy.

The pecan was a popular entry into iNaturalist – one of the native trees that produces something we eat.

Many students were surprised that there are different kinds of oaks – easy to tell by just looking at their leaves.

There were toads hanging out near the pool on the first three days – laying eggs.

They liked the wells around the pool where the water was shaded by the cover.

By the fourth day they were mostly gone and we found one further away into the trees and brushy area.

On Tuesday it rained and on Wednesday, the participants found quite a few mushrooms in several areas where the grass is mowed.

One the last day – the highlight (for me) was a lacewing one of the students managed to capture. We photographed it in a magnifying box

Then released it….it paused for a few seconds for me to get one last picture.

At the end of each day - there is hand washing and then a picnic lunch. On Monday and Thursday, the picnic was on the lawn in front of the Manor House. On Tuesday is raining and the BioBlitz picnic was inside the big tent used for weddings at Belmont. The students sat on the carpet under candeliers. The same location was used for Wednesday too since the lawn was still very soggy.

After lunch - it's time for the students to return to school on their buses...the Belmont Bioblitz field trip is over. But - the collection of pictures and descriptions in iNaturalist has grown each day of the event - quite an accomplishment.

Umami Flavor on the Rise – The ‘pleasant savory taste’ of soy sauce, hard cheeses, and mushrooms or nutritional yeast….but how to get the flavor without high sodium.

Changing the world, one fridge at a time – What can we do about food waste? The problem is in the production side in the developing world and the consumer side in the developed world…so in the US, it is in each of our refrigerators and pantries. I’ve gotten better over the past few years and rarely have anything spoil. I also dry orange peels instead of putting them into my compost!

Green light for plant-based food packaging – Part of the solution to food waste? Based on this story from Science Daily – I’m not sure this one is ready for prime time.

Similar legal action is pending in North Carolina, Colorado, Pennsylvania and Massachusetts.

Mercury Transit

Mercury past in front of the sun on Monday morning this week. My husband set his camera on a tripod with a solar filter in our driveway and got one reasonable picture before the haze became thick clouds over the whole of central Maryland where we live. The small dot to the bottom of the disk is Mercury; the upper one is a sunspot.

My daughter had better luck in Tucson. The transit was already underway before the sun came up but it was a clear, sunny day. The transit lasted until about 11:30 AM local time. She had organized an event on the mall at the University of Arizona – complete with solar telescopes and a scale model of the solar system. When I talked to her later in the day she said they had several 100 people stop by to take a look through the telescopes and understand what was happening….and how it relates to the way exoplanets are discovered! She spent 2+ hours in the sun talking to people – sharing sunscreen with the other volunteers.

Four Ways to Explore the News through Maps – This post was for teachers (and via them to their students)…..but could be interesting to just about everybody. It is a different way to access news.

Pulling it all together – I took a Systems Biology course from Coursera last year and realized the need to integrate what has been compartmented for study – a needed simplification until recently. Systems Biology requires computers and models that have a lot of similarities to those for research into global weather or astrophysics. This article highlights 4 strategies for hunting new cancer targets.

Dreamlike Watercolor Paintings of Iconic Skylines Around the World – How many of these skylines do you recognize?

Fructose alters hundreds of brain genes, which can lead to a wide range of diseases – Interesting research done with rates. Fructose was found to impair memory but rats given DHA (an Omega-3 oil) along with the fructose performed comparably to rats that were not on the fructose diet.

Satellite maps shows explosion in paved surfaces in D.C. region since 1984 – I moved to the Washington DC area in 1983. A lot has happened since then. On the ground, the increase in paved surfaces has not kept up with the number of cars trying to get from one place to another.

Learning Log - April 2016

The majority of learning in April was experiential rather than formal course work although it seems that I always have at least one course in progress or scheduled!

I learned about mealworm cookies and Fresh Paper (for keeping strawberries fresh longer) while during my volunteer gig at my county’s STEM Fair and

Realized that I was glad cooking for 12 people was not the norm for me (it is quite a bit more work that cooking for 2-4) and

Was pleased that I didn’t panic when an opossum carcass turned up beside the stream where 7^th graders were going to appear to search for macro invertebrates in a few minutes (no shovels were available so we pushed the stinking mess into a bucket and dumped it into some nearby brambles).

I did take a macro photography class via Creative Live: The Art of Seeing: Macro Techniques for Flowers and Plants with Frans Lanting. I wanted the course on the day it was broadcast (and thus ‘free’) and then have been experimenting with selective focus since then. One of my first attempts is the picture below. It is fun to ‘fool’ the autofocus on my Point and spShoot camera (a Canon Powershot SX710 HS) into creating blurs in the foreground and background.

I also finished the second unit of the Soul Beliefs course available via Coursera from Daniel Ogilvie and Leonard Hamilton at Rutgers. I’ll do the third and last unit after the spring field trip season is done – maybe start in mid-June.

Getting to the Root – 18 genes are related to hair related traits --- but we are only beginning to understand how they work.

How do we get our drinking water in the US? – With Flint, Michigan’s water problems, awareness is increases across the country that we should not take our drinking water ‘goodness’ for granted. For a more chemistry perspective – take a look at Water Treatment – from Reservoir to Home from Compound Interest.

Genetic Resilience – A study of half a million human genomes, reveals 13 adults that had mutations for 8 different severe childhood genetic disorders…yet had no reported signs of the disease. We have a way to go in understanding how genes work as a system; none of them work in isolation and our studies of them in a standalone fashion is a simplification too far.

Are hazardous chemicals in your cosmetics? – The 4 to look for and avoid are: phthalates, parabens, triclosan, and oxybenzone because they interfere with the body’s natural hormones.

Thyroid tumor reclassified to curb over diagnosis of cancer – The detection of tumors has outpaced the research about what tumors need treatment versus those that are relatively benign. This is a case where a type of thyroid tumor previously classified as ‘cancer’ is being reclassified as non-invasive and with a low risk of recurrence. Are there more tumor types that patients are worrying about now that will eventually be reclassified along these same lines?

Microscopic Iridescence of Peacock Feathers – I’ve always been fascinated with peacock feathers. This article zooms in closer to the feathers and uses photo stacking to get the depth of field so that the structure is in focus.

Longer maternity leave is better for infant health – The article is about a study done comparing outcomes of paid maternity leave in low and middle income countries around the world….but toward the end, there is a reminder that the US is one of the few countries in the world that has no paid maternity leave mandate. Aargh! I was lucky enough to work for a company that paid 8 weeks of maternity leave when I had my daughter; it was considered a medical leave.

STEM Fair as Prompt

I was a judge for out county’s STEM (Science – Technology – Engineering – Math) Fair last Saturday. It was a well-organized event and I enjoyed it just as I have in years past. Every year the students seem to be better prepared and their projects even more interesting. This year I was judging 8^th grade projects and afterwards I thought a lot about how much things have changed since I was in 8^th grade. It’s been close to 50 years!

I did not participate in a Science Fair when I was in 8^th grade although I was in a general science class. It was not a required class and I was 1 of 2 girls in the class. These days the need for STEM literacy is even greater than it was 50 years ago and the schools are striving to upgrade curriculum to keep pace with the needs of the modern world. The students participating in the STEM Fair were the best from their school – and there were more girls than boys. I’m glad that more girls are participating these days but it’s very important for all students to be savvy about these topics.

8^th grade for me was ‘junior high’ but the more popular term these days is ‘middle school.’ My junior high was fed by neighborhood elementary schools and reflected the racial and ethnic diversity of those neighborhoods which were very homogenous (later racial integration would be achieved via busing); 99% of the student body were Caucasian. In my area now, the neighborhood elementary schools still feed the middle schools. The big difference is that the neighborhoods are racially and ethnically diverse so the student body is too. The students at the science fair were representative.

When I was in 8^th grade there were only a few instances when I was asked to present anything; it was not a focus in junior high at all. In high school – debate teams provided that experience to a few students. Now, the ability to present your ideas or work is part of the educational experience. It was clear that the 8^th graders had practiced their presentations and had anticipated the types of questions the judges were asking. Some of the projects were done by 2 person teams and their presentation was orchestrated so that both students talked and interacted with the judges.

Many of the students acquired things for their experiments that would have been very difficult to obtain (if they existed) 50 years ago: mealworms, empty gel caps, open top field chambers for saplings, iPads/smart phones to display pictures, and an online memory game. It is easy to acquire things like this now. I suppose that the student could have grown mealworms…but it would have made the experiment much more time consuming and maybe even distracted from the experiment.

The families of these students are most likely different than those from 50 years ago too. Fifty years ago fast food was an infrequent thing, most mothers worked part time or were at home when students got out of school, the school was not air conditioned and that was true for a lot of homes too, there were no computers, most students had one or more siblings, and jeans were not acceptable attire in many schools.

The big scary thing in the 1960s was nuclear war. As an 8^th grader it was something I was well aware of. It was related to science/technology just as the new big scary thing is for these students: climate change. Several of the students related their project to climate change --- one quite passionately.

There have been a lot of changes and as I think about them now – it is important that we integrate everything into the way we really want to be for right now and into the future. The students I met at the STEM Fair seem to be achieving that. I applaud them and the people (parents, teachers, friends, etc.) that support them.

Family Web Sites

My daughter and son-in-law are graduate students at University of Arizona and they have set up web sites. It’s one of the things grad students need to do as they prepare for the next step after grad school. Both of them have some outreach items that are of broader interest:

My daughter’s site has instructions for how to make a Pluto globe.

My son-in-law’s site has a video of buzz pollination (slow motions…taken with a high speed camera).

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?

Gleanings of the Week Ending April 2, 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.

19 Different Foods that Surprisingly Bloom Beautiful Flowers – Great visuals and informative too. Think of all the different kinds of pollinators needed for these flowers too.

Fulfilling Water Needs as Big as Texas – The Nature Conservancy has created the Texas Water Explorer – wish Maryland had a similar app although I did find Water Quality Assessment Maps for Maryland which have much of the same information. I liked the picture of the Pedernales – brought back memories of a vacation in the state park along the river almost 40 years ago.

New knowledge for managing tree-killing bark beetles – After learning more about the southern pine bark beetle when I visited Chincoteague, I’ve been more aware of the damage it is causing…noticing articles like this one. There is really no good news.

Monet-esque Micrograph and Bug Brothers and Subterranean settlers and Zika viron and Cretaceous Chameleon – The Scientist almost always includes an image in its newsletters. Here’s a collection from March.

Blood test can predict risk of developing tuberculosis – It would be good if a blood test could do this. I remember having to get chest x-rays for my job since I responded to the TB skin test (i.e. was a latently infected person) …and repeated chest x-rays are not a good thing.

It has fast become antiquated to say that you ‘go online’ – Living constantly online…it’s becoming the norm for more and more people. And even when we turn off our devices, our online world continues while we are away. It is the new normal.

Developing better drugs for asthma, high blood pressure – The point of the project is to avoid complications from drugs that require treatment – separate from the original reason the person was taking the drug in the first place. It’s a good goal but I prefer the research toward interventions that address the root cause of a problem rather than starting with a drug that works most of the time and trying to avoid complications from it – which seems to be the goal of this research.

Sleep: The A B Zzzzs and  Learning with the Lights Out and Desperately Seeking Shut Eye and Under the Cover of Darkness (infographic) and Who Sleeps? And Characterizing Sleep (infographic) – The Scientist has had a number of interesting articles about sleep. I wonder how often a person’s sleep (or lack of sleep) is the primary cause of a health issue….and how often doctors decide to treat a sleep problem unless is overwhelming obvious that sleep is the problem. Some sleep problems may be very difficult to treat and may require a significant change in lifestyle which is often very difficult.

These Ancient Trees Have Stories to Tell – I like trees…and these are artfully photographed. They were printed in black and white; I think I like trees in color more.

The Artificially Intelligent Doctor Will Hear You Now – I like the idea here – particularly that it takes into account the patient’s history and circumstances…not just symptoms. One of the things I have observed is that doctors typically key off one or two recent test results rather than taking the patient’s full history into account. They have the problem – like all of us – of being overwhelmed by data. Having an AI that would take all of that into account would benefit the doctor by saving a lot of patient history review time and the patient would get a more informed diagnosis and treatment.

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).
