Josey Ranch Lake - February 2015

In my last family visit to Carrollton TX, I discovered that the round trip walk to Josey Ranch Lake was less than 2 miles so I did the walk several times and photographed birds each time. It turns out that during the winter quite a few people feed the birds so there are gatherings of birds near the boardwalk area and at the reed end of the lake where someone always seems to be offering food to the birds (sometimes the nutria too - although I am sure it is not a good idea to encourage an invasive species).

The well-mannered ducks and swans seem to feed with a fair amount of graceful sharing of the bounty. The coots (small black birds on the water with pointed beaks) can get contentious with each other.

If the ring billed gulls show up there are all kinds of acrobatics. They tend catch the food mid-air or just as it hits the water. The coots are the only ones that seem to challenge them! In the incident I saw - the gull always won.

I noted two ducks that I had not seen in the summer and, when I looked them up on allaboutbirds.org they are ducks that winter in Texas…traveling north when it gets warmer in the summer: the lesser scaup

And northern shoveler.

It is a lot easier to identify birds if I manage to take a good picture! My favorite picture from all three times is this last one - the swan with its wings frothed.

Master Naturalist Training - Week 1

I became a Master Naturalist trainee last week….1 of 8 day long classes finalized with an exam. It is a good thing that the classes are spread out over 9 weeks (longer if there are snow days) since there is a lot to absorb if the first today is the norm.

The topics for the first class were geology and insects…and it was intense. I appreciated the renewal of note taking skills that the Coursera work had prompted since these lectures were fast and furious even though I had done the pre-reading and had previous exposure to both topics. The day after the class I transcribed my handwritten scribbles into my computer - realizing that I would not be able to decipher them once it wasn’t ‘fresh’ in my mind. I also went off onto tangents following web resources the instructors referenced.

The most time consuming tangent was the Maryland Geology for Education site which provides layers of information overlaid on a zoomable map. The map had been used during the lecture so I knew a little about how to operate it. I looked at the ‘Piedmont Counties Geology’ overlay (with transparency at about 50% so I could see streets and structures through the colors) for around my neighborhood. The major rock under my house is schist; taking a short walk from my backyard down to the river passes over a granite intrusion; to the east across the street from house gneiss is the major type of rock. Within less than a mile - where the Community Supported Agriculture farm is located - there is quite a mix of gravel, sand, and clay (sedimentary rock). Wow! I’m amazed at the geologic variety close at hand.

Another tangent - on the insect side - I read an article referenced by the instructor Attracting Beneficial Insects with Native Flowering Plants and then proceeded to spend a lot more time browsing the Xerces Society for Invertebrate Conservation. I am still looking at new items from the site. One of the first things I looked at was one of the identification guides (under publications): Field Guide to Migratory Dragonflies. I can hardly wait to get identifying photographs at Kenilwork Park and Aquatic Gardens this summer.

Some other observations from the first class:

  • I am not used to sitting for most of the day. Even though there were plenty of breaks and some activities that had us moving around the classroom - it was a more sedentary day that I prefer. Will I get up and pace around the back of the classroom next week?
  • The final exam is take-home and open book. Hurray! If it was more like the SAT, I probably would not have signed up for the program! Tests might be necessary but it is certainly not something anyone enjoys.
  • I enjoy the before and after days of the class as much as the class day!

Stay tuned to my continuing adventure as a Master Naturalist Trainee.

Gleanings of the Week Ending February 21, 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.

Add nature, art and religion to life's best anti-inflammatories - Yet another reason to savor the awe of nature, art and spiritually - if you need one. Including these in day-to-day living should not be a hard sell but many times they fall by the wayside if our lives get too full of other things. They don’t go on a ‘bucket list’ for some other time; they need to be included every day!

In a crisis, the bigger your social network, the better - This research indicates that more extensive social networks are a backup strategy for crises - or at least it was in the pre-Hispanic Southwest. Is it always the case? Sometimes it seems that all the increased communication going on in the modern world has increased the divides rather than built positive networks.

Never trust a corporation to do a library’s job - The history of Google and Internet Archive as ‘library.’

High Stakes in Declining Monarch Butterfly Populations and Six Ways to Save Monarchs - The rapid decline of Monarch butterflies is very sad….but there are things to do. I am going make the dominant plant in my chaos garden beginning this year!

How the Eastern tiger swallowtail got 'scary' - Another butterfly story. I bought some tiger swallowtail earrings (one is the caterpillar and the other is the butterfly) so this article captured my attention.

The Chemical Compounds behind the Smell of Flowers - The smell of roses, carnations, violets, lilies, hyacinth, chrysanthemums, and lilacs. The only flower whose smell is not produced with compounds containing ring structures is the lily.

Increasing individualism in US linked with rise of white-collar jobs - A lot has happened in the last 150 years…including a higher percentage of the population working in white-collar jobs. This study showed that the trend in type of job was more correlated with the trend toward individualism that some other changes such as urbanization or frequency of disease or disasters.

How Tourist Garbage Causes Yellowstone's Morning Glory to Change Color - The color of the Morning Glory pool is no longer the blue color of its namesake. Too many people have thrown coins, rocks, and trash into it. This article reports on why the trash caused the change.

Larger area analysis needed to understand patterns in ancient prehistory - In the past, the main tools used to study prehistory only addressed very small areas. Now there is an acknowledgement that some conclusions cannot be drawn with only those small samples and technologies that can look at larger areas are being applied more frequently to understand how cultures responded to population pressure and climate change in particular.

An ocean of plastic: Magnitude of plastic waste going into the ocean calculated - More than 4.8 million metric tons of plastic waste enters the oceans from land each year; it could be as high as 12.7 metric tons. That’s a lot of plastic. The ocean seems so vast…but we are pushing it in ways that it may not be able to absorb without huge impact to itself and the planet.

Electrochromic polymers create broad color palette for sunglasses, windows - What fun! I’d like these in the windows of my office rather than sunglasses! Maybe the window could be powered by a solar cell.

3 free eBooks - February 2015

It was hard to pick my three favorites this month. I settled on three topics: Mayans, Fungi, and Chinese Painting.

Maudslay, Alfred Percival. Biologia Centrali-Americana, or, Contributions to the knowledge of the fauna and flora of Mexico and Central America. London: R. H. Porter and Dulau & Co. 1902. Four volumes available from the Internet Archive: volume 1, volume 2, volume 3, volume 4. These books focus on the archeology of a region - primarily Mayan - in the late 1800s that has gotten more attention over the past century. There are lot photographs (sometimes with people to help understand the scale of the ruins) and drawings. There are also a few color plates. The photograph at right is quite well know (it’s in the Wikipedia entry for him and is in many textbooks). Many of the ruin were roughly cleared of vegetation or still partially obscured at the time Maudslay documented them.

Banning, Mary Elizabeth. Fungi of Maryland. Available via the New York State Museum here. This is an online exhibit more than a book but I am including it here to show off the beautiful illustrations done by Mary Banning. She began her work in 1868 and continued for over 20 years producing 174 detailed 13” x 15” watercolor illustrations. The online exhibit includes 48 of them. Unfortunately - she was unable to get her work published; she sent it to the New York State Museum as a ‘safe place’ in 1890; it was found again 91 years later in 1981.

 

Barnhart, Richard M. Peach Blossom Spring Gardens and Flowers in Chinese Painting. New York: The Metropolitan Museum of Art. 1983. Available from the Internet Archive here. Some of the images are very colorful and some are muted. I particularly liked the muted image of the lotuses.

Butterfly House at the Texas Discovery Gardens

The Butterfly House at the Texas Discovery Gardens is a colorful place to visit in the winter. I was there earlier this month when I travelled to Dallas. There are lush tropical plants and butterflies! It was not crowded even though it was a weekend.

The Butterfly House is a multistory conservatory with a ramp that wonders through the tops of taller foliage down to a courtyard with water features. The butterflies were on all levels but densest near the water.

The enclosed space was bigger than the Tucson Botanical Garden butterfly exhibit but there were not as many butterflies when we were there and not as many people either.

The standout memory of the day was color - since so much of Texas (and Maryland) is mostly drab in winter. The flowers and fronds were a welcome change from winter overall.

We stayed for the daily release of newly hatched butterflies at noon. They were brought out in a net barrel. The tiger swallowtail did not want to leave the safety of the container. Maybe its wings were not entirely dry.

Some of the new arrivals left the container quickly but chose to walk rather than fly!

Children gathered around to see the release and noticed a more battered butterfly nearby on the ground. They tried to entice it to safety (out of the walkway).

Butterflies and conservatories….always a pleasant interlude.

 

Zooming - February 2015

It is often hard to find color in the middle of winter. The colors seem to be mostly white and brown…so the bits of color are appreciated more:

  • The flower and fiddlehead in the green house
  • The red of a pigeon’s eye
  • The flash of blue when a jay pushes the leaves around in the forest
  • The blue sky on a sunny day
  • The blue powder design on a butterfly’s wing

It is very cold today and there is still snow on the ground from a few days ago. But I enjoy the scene of the forest in winter from my office window - staying warm indoors.

Enjoy the February zoomed images!

Gleanings of the Week Ending February 14, 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.

Behind the Photo: Paul Nicklen’s Leaping Penguins - Video of leaping penguins….and how it came to be.

This Scientific Paper Proves That Nature Never Stops Weirding Us Out - Did you know that frogs retract their eyes into their heads to push crickets down their throat?

Older adults: Double your protein to build more muscle - Maybe the recommended daily allowance for older adults needs to change.

Your Two-Minute Break to Enjoy Wildlife Along The Moose-Wilson Road In Grand Teton National Park - A short video….I enjoyed the reminder of how much I enjoyed a vacation at Grand Teton National Park years ago.

Expert panel recommends new sleep durations - Is your sleep duration within the new recommended range? Mine is. I was intrigued that there were two new categories added for this study: Young adults (18-25) and older adults (65+).

A surprisingly accurate map of the U.S. made with 600,000 bridges — and nothing else - Map created from data in the National Bridge Inventory maintained by the Federal Highway Administration…includes bridges that are longer than 20 feet. That’s a lot of bridges!

6 Wildlife Facts for World Wetlands Day - World Wetlands Day was Feb. 2….enjoy the facts and photos.

Fake Meat Gets Real - There are lots of new ways to get protein…some better than others. I liked the last sentence “you’re better off getting most of your protein from whole foods, including legumes, nuts, seeds, and whole grains.”

Review of nonmedicinal interventions for delirium in older patients - Good! My observation has been that older people on multiple medications have side effects (like increased delirium) that are often worse than the symptom being treated….so it seems prudent to resist adding medications unless they are absolutely necessary.

An Inventory of Protected Bike Lanes - Bikes are becoming more popular for recreations and transportation in many places around the country. Bike lanes are one way cities are responding. By the end of 2014 there were 191 around the country. I hope the trend continues!

Sustainability - Focus on Light

One of the luxuries we often times take for granted is the availability of light at the flip of a switch. It makes it possible for us to do just about anything we want at any time of the day or night. What are the elements of sustainability related to light?

Lighting requires energy so:

  • Use energy efficient fixtures and bulbs. All our lamps that originally had incandescent bulbs now have compact fluorescent bulbs and the overhead lighting fixtures in the kitchen/basement utilize the tube style fluorescent bulbs. There are still a few halogen floor lamps in our house but I try to not turn them on in the summer when the heat they generate is at cross purposes with the air conditioner! The lights around the mirrors in the bathroom and the dining room fixture still use incandescent bulbs and I don’t plant to replace them.
  • Turn off lights when they are not needed. ‘Need’ is full of nuance. When I read - I need a light. But how much extra light do I need if I am reading on a tablet…or if it is in the daytime and my chair is by a window? How important are some lights to feeling secure? We do have a timer system in our house that turns a few lights on and off even if we are not home. If we are home - the lights are on in the evenings and early mornings in the rooms where we are….and not in other parts of the house.

Another element of sustainability when it comes to light - is the influence light has on health. It is an area of research and harder to internalize that the energy consumption issue.

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.

Millions of Mutated Mosquitoes Could Be Unleashed In Florida—On Purpose - There is concern that tropical diseases like Dengue and Chikungunya will become more common in the US as the climate becomes warmer. Reducing the number of mosquitoes that spread the disease may become a priority and there biotech firm Oxitec has experimented in the Caymen Islands and Brazil with GMO mosquitoes that suppressed the population there by 96%.

Swarm of microprobes to head for Jupiter - The probes will burn up in Jupiter’s atmosphere was send a mass of data for 15 minutes. A lot will be learned about the atmosphere of the planet.

Assateague Island National Seashore Turning 50 This Year - Chincoteague/Assateague is my favorite place on the Eastern Shore of the Chesapeake Bay….I’ll keep an eye out for extra activities that celebrate its 50 years as a National Seashore.

Mindfulness-based program in schools making a positive impact, study shows - Something to combat the stress of modern childhood?

Top 25 Wild Bird Photographs of the Week #75 - A feast of bird images from around the world. I always enjoy looking through these collections.

This Glorious Gallery Highlights A Myriad Optical Delights - Wow - images from a visual celebration of the International Year of Light. Next time I go to Arizona - I want to see Antelope Canyon

The origin of life: Labyrinths as crucibles of life - This article caught by eye for two reasons: it linked well with the Origins course I finished recently on Coursera and I like the picture of lava.

Two Graphs Highlighting Growth Surge in US Solar Market - With oil prices lower, will the trend continue in 2015?

Food Industry Drags Its Heels on Recyclable and Compostable Packaging - The food industry - particularly the fast food industry - is definitely not trending toward sustainable practices (with the possible exception of McDonald’s and Starbucks….and do we really need K-cups anywhere?

A Stunning 3D Cross-Section of Greenland's Ice Sheet - Made using ice cores and ice penetrating radar technologies. Watch the video to understand how it was done. There are three distinct periods of climate reflected in the Greenland Ice sheet.

Poison Dart Frogs at the Tucson Botanical Garden

The butterfly exhibit at the Tucson Botanical Garden (earlier post here) included more than butterflies and plants. There were poison dart frogs that were roaming about the greenhouse. The docent told us they had been imported a few years ago to help control ants and fruit flies; they seem to do a good job! When they first arrived they were about as big as a thumbnail. They are still small - about the size of a thumb.

For some reason - the blue ones (not sure how many of them there are) seemed to be the most active.  These frogs tend to climb around on plants and objects rather than jump. They are quite agile.

They seem to be constantly in motion and like to be under vegetation. One got close to the door and one of the volunteers moved the frog back to some plants. These are non-native to the US so are carefully contained in the moist greenhouse that is the butterfly exhibit in Tucson!

Which color is your favorite? I think the blue is mine but maybe it is because I managed to photograph them more easily.

Pinyon Pines and Birds in Arizona

Two topics today - both from Arizona: pinyon pines and birds.

Pinyon pines are part of the landscape of the Grand Canyon. I have always been fascinated by their cones. They are short and squat and often full of sap. I learned that the hard way on a trip across New Mexico in a new car 30+ years ago. I picked up some pinyon pine cones and put them on the dash of the car - enjoying their wonderful smell as we continued our road trip. The sap stayed on the dash for years! I am enjoying the pictures I captured this time. The first picture is of a cone that has already lost its seeds; the second and third are developing cones.

I accidently took some good bird pictures in Arizona. They were accidents in that I was not set up to photograph birds; I was just being opportunistic. The varied thrush was in the parking lot of the Petrified Forest Visitor Center! The bird is a little out of normal range according to allaboutbirds.com.

The next three birds were in the alleyway outside my son-in-laws research greenhouse in Tucson (I was waiting outside after getting too hot in the greenhouse). The mockingbird kept an eye on every move I made but rummaged in the pebbles for food. This bird lives year round all of the US but they are usually too nervous for me to photograph.

The curve-billed thrasher felt secure on the electrical line. The wind ruffled the feathers periodically making the bird look rather scruffy.

The white-wing dove was also overhead on the lines. The red eye outlined in blue and the white tips on the wings are distinctive….and the ruffling of the feathers by the wind is too.

I am learning to always be prepared for bird photography in unlikely places!

Coursera - February 2015

Only two courses in progress for me right now! It takes a lot of will power to not sign up for more; there are competing activities this month: travel and classroom-based courses. Here are the two that will keep me busy in February.

Circadian clocks: how rhythms structure life (from Ludwig-Maximilians - Universitat Munchen (LMU) is off to a good start with a mix of history of the research and vocabulary. It’s a topic that is interesting and has lots of implications for health and well-being.

The Land Ethic Reclaimed: Perceptive Hunting, Aldo Leopold, and Conservation (from University of Wisconsin-Madison) started off by having student pick an avatar that reflected their perspective of the course topic. I chose ‘naturalist;’ it will be interesting to see the demographics of the other students in the course. I like the way the instructors are using surveys and probing questions along with the typical MOOC videos, reading list, and discussion forums.

Two courses finished in January:

Recovering the Humankind’s Past and Saving the Universal Heritage (from Sapienza University of Rome) was a more philosophical course than I expected. It included discussion of the science/technology of archaeology and how it developed over time which is what I expected. But the more thought provoking parts of the class were about the concept of ‘universal heritage’ and why it is important; the relationship of wars and destruction of material culture of the past is striking. It happens alongside the human lives lost and plight of refugees in Syria and Iraq.

Origins - Formation of the Universe, Solar System, and Life (from University of Copenhagen) was a very broad course taught by a team of people from the Natural History of Denmark. It was a good update on what has been discovered since I was in college in the 1970s. Scanning Science Daily over the years helps - but it was refreshing to get a fresh update that tied it all together in an organized way.

As usual - I thrive on having some new topics to learn about and Coursera is a prime avenue for that. Hurray for Coursera!

Gleanings of the Week Ending January 31, 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.

At 90, She's Designing Tech for Aging Boomers - She was a designer all her life! Good for her…for the company that is using her ideas…good for consumers.

Telescope to seek dust where other Earths may lie - This article caught my attention because my daughter recently was there for a ‘field trip.’ The Large Binocular Telescope Interferometer (LBTI) is run by University of Arizona.

Sleep tight and stay bright? Invest now, researcher says - I am so lucky to be able to go to sleep easily and awake on my own after 7-8 hours. This study says (once again) that good sleep is linked to a lot of good health and mental outcomes. One of the joys of post-career is not waking up with an alarm clock!

The lip of the caldera - I couldn’t resist sharing this picture of the inside wall of Santorini.

Decorative and flexible solar panels become part of interior design and the appearance of objects - I enjoy technology that is functional and beautiful. So many times the engineers focus exclusively on functionality.  

Should arsenic in food be a concern? - The answer in this article was ‘no’ but I was frustrated that they focused primarily on plant foods and did not mention the status of nitarsone/histostat (an organoarsenic compound used in poultry production).

Boston's leaky pipes release high levels of heat-trapping methane - Not good for Boston and probably many other older cities….and worse is that there is little economic incentive to make the necessary investments to reduce the incidental losses from leakage.

What to do in a flu epidemic? Stay at home and watch TV - This was a study to assess the effectiveness of non-pharmaceutical interventions (NPIs) during epidemics - particularly of flu.

The Chemistry of Highlighter Colors - Download the graphic (link at the bottom of the article) and take a look at how the colors are made.  Note how that they have a lot of ‘rings.’

Is Hospice Losing Its Soul? - My grandmother’s last few months were spent at home under hospice care; the hospice support to her and our family was invaluable. This article is troubling because the trend in hospice is toward standardization/institutionalization….not the tailored, compassionate practice that has been the strength of hospice from its inception. I hope there are enough people that will demand that hospice stay true to its roots.

Grand Canyon National Park

I’ve been to Grand Canyon National Park three times:

  • When I was in high school - in early spring 1971 when I walked a little ways down Bright Angel Trail then turned back when it started snowing.
  • In May 1983 when my husband and I walked down the Bright Angel Trail to the plateau level. I remember blisters from the too-new hiking books and my legs feeling like jelly for most of the walk back up.
  • In January 2015 when it was cold and breezy. We drove to the park through early morning light and saw a bald eagle landing in the top of a pine tree beside the highway. I wasn’t fast enough to get a picture but it started out the day right. The pictures below are from the visit a few weeks ago.

It is hard to fathom the sheer size of the place. The rim trail on the South Rim - accessible from many points - is an easy walk to try to get perspective. We were early enough that the haze had not burned off completely and sometimes the vegetation seemed to glow from light within.

There has been a lot of building in the main park facilities since 1983. I liked the way the paving incorporated different colors of concrete to make designs - spirals and gentle curves. But we didn’t stay in the developed area long. We decided on our plan for the day - settled on where we would eat lunch (Maswik Lodge Food Court) and began working our way toward Hermits Rest stopping at just about every overlook. After lunch we headed in the opposite direction (toward Desert View) where we would leave the park and head to our hotel about sunset. Along the way we saw rapids and twists of the river below, a mini-snowman, beefy crows, and the zigzag of a trail into the canyon. Sometimes I took pictures of lichen and small plants just to not be overwhelmed by the Grand Canyon vista!

I am already thinking about when I can go again!

Ten Days of Little Celebrations - January 2015

Noticing something worth celebration each day is an easy thing for me to do. The habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations’ - as had been the usual for the past few months. Here are my top 10 for January 2015.

Winter

AZ Sarah IMG_0123.JPG

Snow in Tucson. The year started off with a pictures from my daughter of the snow they got --- on the palms and cactus near their apartment. It was a beautiful scene to celebrate the New Year.

Fox. A healthy looking red fox walked through our back yard then trotted behind several other houses before turning into the forest. I watched from the window of my office - celebrating the grace of the animal as it moved through the winter landscape.

Fog. The forest and our neighborhood filled with fog. The temperature was in the upper 30s. It seemed like the fog damped sound as effectively as it did sight - celebrating a warm house in the isolation of winter.

2015 01 IMG_5824.jpg

Snow. Snow that falls when I can simply stay at home until it melts or the streets are cleared by the plows is my favorite kind of day. It is the classic winter scene worth celebrating.

Other

Dishwasher. Our dishwasher became very loud so we arranged for servicing - anticipating that it would have to be replaced. Hurray! It was quickly fixed and our kitchen is a quieter place.

Zentangle® class. I saw a blurb about a Zentangle class offered at the local 50+ Community Center. It was a good incentive to investigate the place! I’ve been to the first of four class sessions and am enjoying daily ‘tangling’. I’ll post a slide show of my creations once I’ve accumulated a few more. I’m celebrating both the class and learning about the 50+ Community Center.

Arizona and Tucson

Bald Eagle. In recent years, the bald eagle population has increased on the east coast and we see them more often….but when I saw one as we drove into Grand Canyon National Park - settling into the top of a pine tree - it was a first sighting in the west for me. Hurray!

Grand Canyon. Awesome place. I’ve been there before --- it is worth celebrating again and again.

Painted Desert/Petrified Forest. The times I’d been before were in summer and late spring. This time it was decidedly cool/cold. The colors were deeper in Painted Desert because it had snowed/rained. The Petrified Forest glistened when the sun came from behind the clouds. Both places are special…and worth celebrating.

Tree Ring Lab. I’m celebrating that the place lived up to my expectations - interesting from scientific, architectural and historical perspectives. If I lived in Tucson - I’d sign up as a volunteer docent.

Gleanings of the Week Ending January 24, 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.

Is it possible to reset our biological clocks? - I have just started a Coursera course on circadian clocks so am paying more attention to articles on the topic. This one is from ScienceDaily.

Wild pollinators at risk from diseased commercial species of bee - Honeybees, bumblebees, and social wasps  are all colony living insects that makes the transmission of disease within the colony very rapid…and now there is evidence of transmission between colonies, even colonies of different species.

Google Talking To Automakers about Building Autonomous Cars - I would like to see autonomous cars…but is it just wishful thinking for the near term (say 2020)?

This Ancient Pigment Could Soon Be Used to See Through Your Skin - Egyptian blue (calcium copper silicate). And now it’s becoming a medical technology too. Other applications of Egyptian Blue in an article from Antiquity Now.

How to Uncover a Skeleton’s Secrets - From National Geographic. The examples in the article is from a project in northern Peru

One Scientist's Race to Help Microbes Help You - There has been a lot discovered about the human microbiome…but translating the new knowledge into treatments has been slower. This is a story about the American Gut Project - a massive citizen science experiment - which is focused on accumulating enough data to enable the move toward treatments sooner.

Humanity Is In the Existential Danger Zone, Study Confirms - Scary stuff. Are we engineering a wave of extinctions on our planet that will eventually include ourselves? We are pushing against and past several planetary boundaries.

A Smart Grid Infrastructure Demands Increased Engineering Smarts - One of the skillsets needed for the future. The article is about the program in Syracuse University’s College of Engineering.

Counties Lag Behind National Recovery, Report Finds - A breakdown of ‘recovery’ at the county level reveals key economic indicators on a more granular level that we usually hear about. The clickable version of the map is available here.  I found that the county where I live has recovered 2 of the 4 indicators (which is considered ‘recovered’) but where my daughter lives in Tucson has not recovered any of the 4; having visited Tucson for the past 3 years, I do notice that things have improved - but they are not back to the levels prior to 2008.

Breathtaking Frozen Bubbles Look like Elegant Glass Ornaments - I hope we have a cold day soon so I can try making frozen bubbles like this! I’m pretty sure it takes lots of practice to make them look as good as these!

Tucson Butterflies

It was warm enough for butterflies to be active on the lantana on the University of Arizona campus week before the last but the bigger butterfly treat was at the Tucson Botanical Garden’s Butterfly and Orchid Pavilion.

The pavilion is a warm, misty place where the butterflies are numerous enough to get some good photographs - after the camera acclimates to the steamy environment. The exhibit gets new additions each day a pupae in the building next door hatch and are brought into the pavilion. We saw a glass wing being released and then a very large moth - a cecropia. I included two pictures of it in the slideshow below.

The butterflies only live about 2 weeks. Some of them don’t eat in their adult phase - others are active on nectar plants. Caterpillars and their food plants are not part of the exhibit (all the pupae come from the native countries for the butterflies).

What a delight of warmth and color in January!

Gleanings of the Week Ending January 17, 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.

Under-the-Radar Environmental Stories for 2015: The Furtive Five - Five stories and some comments about trends in environmental reporting in mainstream media. Did you know that 33% of the children living the Tehran have asthma or air-pollution related allergies?

Technology to recycle all type of plastics without using water - This sounds like a good technology for the future…and in areas where water is already scarce.  The research/development was done in Mexico.

Chitosan: Sustainable alternative for food packaging - Chitosan is made from shells of crustaceans. The process for manufacturing is not currently economical but could become so….and the material biodegrades much faster than the 100-400 years it takes for most plastic packaging today. I wondered if the packaging would cause people with allergies to shellfish a problem. The research/development was done in Spain (Basque Country). This and the article just above caused me to wonder if countries other than the US are surging ahead when it comes to enablers for a sustainable Earth.

Sweet potato leaves a good source of vitamins - I just discovered that sweet potato leaves are edible from my CSA last fall. It’s thrilling that they are very nutritious as well. I liked them a lot in salads; they are best if eaten within a few days of being picked so I don’t anticipate they will find their way into grocery stores very often.

6 Birds That Are Champion Flyers - Champion flyers from different perspectives: Arctic Tern, Bar-tailed Godwit, Peregrine Falcon, Grey-headed Albatross, Hummingbird, Purple Martins.

The Chemistry of Decongestants - This was a timely post on the Compound Interest site.

Lose Yourself in These Photos Of Europe's Most Magnificent Libraries - Books and buildings….what will they be in 100 years? They already have a museum quality.

The 19th-Century Photography Trick That Changed How We See Snow - How William Bentley made his famous images of snowflakes….spurs me on to try more snowflake photography next time in snows in my area. I may add a feather to my supplies!

The Daily Routines of Famous Creative People, Charted - Is your daily pattern similar to any of these ‘famous creative people’?

‘Kitchen of the future’ here, now - I like the idea of a high definition backsplash! There is a film available from the location of the materials for the Science Daily story here. I already use my ceramic cooktop as working surface when I’m not cooking on it…so I agree that there are certain components of the ‘kitchen of the future’ that are now.

Gleanings of the Week Ending January 10, 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.

Birding in the National Parks: Return of the Snowy Owls - It looks like this winter will be another one for seeing Snowy Owls in the northern states of the US! There were some sightings in Maryland last winter so I am hoping…

Did Venus Once Have Oceans of Liquid Carbon Dioxide? - Maybe the geological features on Venus (rift valleys, river-like beds, and plains) were may be liquid carbon dioxide rather than water like they are on Earth.

From the Feature Well - This is the summary of 2014 special issues from The Scientist. Looking back at them provides a good review of Biology issues and progress for the year.

The "Rule of 50" Helps You Know When to Give Up on a Book - How do you know when to quit reading a book? Usually I decide via scanning before I every start reading rather than determining ahead of time a number of pages I’ll read before deciding. I can’t remember the last time my scanning failed.

The agricultural changes in the mid-90s killed the milkweed (food plant for the caterpillars) at the edges of fields. Now there needs to be a concerted effort to increase the availability of milkweed.

The Most Amazing Meteorological and Space Observatories Ever Built - Beautiful and functional architecture from around the world.

Significant link between daily physical activity, vascular health - These type of studies come out frequently…with some nuance defined a little better than before. Hopefully no one is waiting for another study to transition some sedentary to active time every day. Now that I think about it - do these studies prompt people to become more active?

A Look Back at Our Most Popular Photos of 2014 - From the National Wildlife Federation. The very first one (a snowy owl) caught my attention.

National Park Service Launches Website Honoring 22 World Heritage Sites in the United States - Did you know that there are 22 World Heritage Sites (a UN designation) are in the US?  Most of them are National Parks…but now all. The list can be found here.
