American Craft Show in Baltimore

Yesterday we made the trek into Baltimore for the American Craft Show that was held there this weekend. We had heard about it from the artists (2400 Fahrenheit) we’d purchased some pieces from in Hawaii. There were an overwhelming number of beautiful things at the show: glass, clothing and accessories, jewelry, wooden art and utensils, metal pieces…I am pretty sure that even though we tried to be methodical and go down every aisle the we missed some of it.

Jewelry seemed to have the most booths. I got a set of copper jewelry (cuff, earrings, and ring) from a Baltimore artist – Allison Fomich. She does botanical motifs so I’ll probably buy more pieces the next time I happen upon her at a local event.

The red and black earrings are from a west coast artist --- they are more 3D than most of my other earrings and they are colors I wear frequently.

The last item I got was an eyeglasses case. My husband was always irritated when my old case snapped shut so he is the one that strongly suggested this fabric case that will be silent!

Of course – we had some narrow misses on more expensive items (larger art glasses pieces). We didn’t find a piece that we both agreed was the perfect one for our mantle.

On the way home I took a picture of a clock tower than I hadn’t noticed before – probably because I have only been taking pictures from the car window recently. It is the Bromo-Seltzer tower and was built originally opened in 1911. It was the tallest building in Baltimore from then until 1923! Check out the Wikipedia article about it here.

Gleanings of the Week Ending February 20, 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.

Snow Rollers – Snow balls formed via weather conditions rather than human hands!

Humorous Charts and Graphs Show What Being an Introvert is All About – Lots of fun….and oh so true! The graphics start with one about the ‘perks of being an introvert.’

Recovery: Saving Lake Sturgeon, an Ancient Fish with a Bright Future – A little bit of history… and the potential of surviving… for this fish species that has been around for a very long time.

Mammography: Is Every 2 Years Enough? – Netting out what the most recent studies have found. But will doctors and mammography centers go with the recommendations? It seems that some mammography centers might be financially motivated to continue to push annual mammograms for everyone – even those over 55.

New study finds clear differences between organic and non-organic milk and meat – This is a study from the UK but the results would probably be the same in the US. I already buy organic dairy and meat… and appreciate that research about the nutritional value fortifies that decision!

The Fungi Within – This article includes a nice table of fungi frequently found in the body. It’s interesting that there are so many and that most of the time they don’t cause us problems. But do we always recognize when they are problematic?

‘Ecologically diverse’ breast cancers more likely to be deadly – Most of the time diversity is a good thing…but not when it comes to cancer. It appears that the general rule that ‘diversity is good for survival’ is true for cancer ‘systems’ too.

Mind and Matter – From the author of a book on the topic. Many patients supplement what their doctors are telling them with other resources…and maybe this is an area (the role the mind plays in our health) we should include when we visualize the educated patient of the 21^st century.

NASA Releases Retro Travel Posters Playfully Encouraging Space Tourism – Fun!

Images of Sound Waves in Water – A little like kaleidoscope images…except with sound waves.

Conowingo in February 2016

We thought the day was going to be sunny - lots of light for photographing birds - but it became cloudy not long after we got there. And it was cold and breezy. The birds seemed more interested in hunkering down and staying warm than fishing even though the dam’s generator were running and churning up lots of water.

There was still some snow on the ground from a snowstorm over a week before. When I took this picture I thought the rock on the right looked like a floppy eared animal coming out of a winter’s sleep!

And what about the maze of ice in this close up of a snow bank over gravel. The melt pattern was not uniform at all.

The river water was moving swiftly and all the snow along the lower bank had melted. The color variation of the rocks has a lot of visual appeal sandwiched between the monotones of water and snow.

There were several birds that flew into the trees. This one has a fish that it finished off from its perch in the tree.

Another just seemed to survey the photographers that were along the fence between the parking lot and the Susquehanna River.

The most interesting of the birds in the trees was the black vulture. Its feathers were fluffed against the cold and ruffled by the wind. I was interested to note the white in the feathers; it is noticeable when they are viewed from below when they are soaring but I had not seen the white when they were on the ground. And look at the claws – they look like evil-looking curved fingernails.

The only Bald Eagle I managed to photography was a little too far away. The eagles are the main reason we go… so I was glad to get at least one picture.

There was another larger bird that caught a fish near the dam….but it flew off to the other side of the river. It was quite a bit larger than the gull.

There was a tree that had some velvety buds. After I got home I did some research. Aargh! It is a Princess Tree - a non-native, invasive species.

As we headed home, I noticed that the ice patches on the road has mostly melted. I drank some more of my hot tea from the Thermos – using the cup to warm my hands.

Gleanings of the Week Ending February 13, 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.

Lava flow crisis averted (for now) – We saw the cooling flow described in this article from Science Daily when we were in Hawaii last December!

We must better communicate the health benefits of nature – Not everyone is outdoors as much as I am --- or has a great view of the outdoors from their office window. I remember an instance when I was outdoors with students on a middle school field trip and realized that many of them thought about the outdoors in terms of streets and parking lots rather than hiking paths, trees, and birds. The hike and what they were seeing was a new experience for them.

Sally Ride reminds us that one thing has not changed for female astronauts – An interview from 1983… the types of questions she got from the press.

Inside the Eye: Nature’s Most Exquisite creation – From National Geographic.

In New Anti-Aging Strategy, Clearing Out Old Cells Increases Life Span of Mice by 25 Percent – A good thing or the modern equivalent of ‘snake oil’? If it does increase life span – how healthy is that extra time?

Sign of early settlement in the Nordic region date back to the cradle of civilization – We think of the transition from nomadic to settlement living happened first in the Middle East but this find in Sweden indicates that it may have happened about the same time in Nordic prehistory.

This uncrushable robot cockroach just wants to rescue you – Building a robot that can compress itself in much the same way a cockroach can…. Another instance of observing nature and implementing the same solution via technology rather than biology.

The Truth about Processed Foods – Every wonder what the difference is between highly, moderate, and minimally processed foods in articles about healthy diet? This article provides some definitions. I changed my food log for a few days to put categorize foods and discovered that most of the foods I consume at home are unprocessed or minimally processed because I make most of what I eat from scratch. There are a few moderately processed foods. The highly processed are things like salad dressing or stir fry sauces; I also drink almond milk which is ‘highly processed.’

Organic Farming could help feed the planet and protect it – A good graphic comparing conventional to organic farming based on some research from Washington State University. One of the authors is quoted as saying: “The challenge facing policymakers is to create an enabling environment for scaling up organic and other innovative farming systems to move towards truly sustainable production systems.” As a consumer – I have already made the decision to buy organic as often as I can.

Tucson Souvenirs

Earrings! They are my favorite souvenirs – not too expensive and small enough to be easily packed for the trek home.

The most unusual earrings I purchased this time were the ones that used cholla cactus stems as a large ‘bead’ (upper left). I noticed the cholla cactus around Tucson because they seemed to be more colorful than just about anything else.

I bought the hummingbird earrings since we did see quite a few hummingbirds during our walks…. again, the earrings are a good reminder of one of our trip highlights.

The bear earrings were a serendipity. I bought them as a reminder of the excellent black bear lecture I attended just before our trip….and I liked the symbolic representation. When I saw the arrow inside the bear symbol I thought of the 20,000 calories a day the bear needs to eat in the fall (does the arrow represent the digestive tract?)!

Views from an Airplane Window

I had a window seat on the flight between Tucson and Las Vegas on the way home from Baltimore last month. That is a scenic stretch from the air. Taking off from Tucson – one notices how flat the area of the city is…and how it is almost surrounded by mountains – some of them with snow at the top.

I saw one of the mines that we saw from the highway as we drove between Madera Canyon and Tucson earlier in our vacation. It is easier to see the pit and the slag from the air.

This looks like another mine – one that is literally taking the top off the mountain.

A little further on I noticed a different pattern in one of the circular irrigation fields. How could that happen. Did the waterline fail in some patterned way?

And then there were massive housing developments with red or white roofs – some around artificial lakes. They seem to build right up the base of the low mountains.

We flew over Lake Mead! I took a lot of pictures but the two below were the best.

As we turned toward Las Vegas there was more snow on the mountains. Sometimes the snow made a crest stand out…snow on one side and not as much on the other – a visual of the ‘rain shadow’ effect that applies to snow too.

Tohono Chul

Tohono Chul was another destination while we were in Tucson in January. We had been there before – in March 2013 and December 2011. The dust and gravel paths through the gardens are pleasant during this time of year when the weather is cooler that in the heat of summer. Some of the paths and courtyards are shady from overhead growth. I enjoy the occasional metal sculptures (the deer in the image below) in some of the more formal areas.

The eye is drawn to unusually looking saguaro. I’ve photographed two of them on previous visits and named them for what they remind me of: Gumby and elephant.

There were two others that I noticed this time. One had no arms but an unusual configuration at the top with a proliferation of pleats and then, seemingly, a bunch of small arms growing straight up.

There was also a saguaro that has fallen over on the ground; the outer part had dried and split apart to reveal the ribs underneath. It provides some protection to the small cactus growing close beside it.

I noticed a new looking wall with cactus growing on it; there are ‘holes’ built into the wall to provide some soil for the cactus.

There was also a wall with accompanying signage that showed the geology of Arizona…the state has a lot of geologic variety!

There were birds about too: the black bird with a crest and red eye is a phainopepla (this one is a male)

And goldfinches feeding at a mesh bag full of seeds.

The most surprising cactus I saw was one that looked like something had eaten the top! What kind of animal would have a tough enough mouth to do that? On the plus side - it does provide a view of what the inside of the cactus looks like.

There were architectural elements to enjoy too: a purple wall in a meditation garden with vines growing on it

And stairs to a roof with pots and lush vine spilling from above.

I spotted several butterflies in the garden. This one seemed very intent on foraging – even with a very battered wing.

I used the zoom on my camera to document some Century Plant seed pods – some already split open and some still ripening.

All in all – there is always something to notice anew at Tohono Chul.

Raptor Free Flight at Arizona-Sonora Desert Museum

We saw the morning and afternoon Raptor Free Flights at the Arizona-Sonora Desert Museum when we were there in January. The museum brings out birds that are trained to swoop for bait providing great views of the birds in flight and out in the open area of the desert museum’s land. The views of the birds during the free flight would be very time-consuming to duplicate in the wild and lots of people – including me – were taking pictures.

We saw two different kinds of owls: A Barn Owl

and a Great Horned Owl. I couldn’t resist taking several perspectives of this bird. The wings are more complex structures.

The Prairie Falcon was probably my favorite...swift and beutiful.

There was a ferruginous hawk at the end of the morning program - quite a size contrast to the praire falcon!

All of these are solitary hunters. The Harris’s Hawks, the last birds in the afternoon Free Flight, live and hunt as a group so their free flight is as a group. Their acrobatic interactions were too fast for me to photograph!

Arizona-Sonora Desert Museum

The Arizona-Sonora Desert Museum is a favorite outing during our Tucson vacations. The drive through the Tucson Mountain Park to get there just sets the stage for a day enjoying all the wonders of the museum. There are lots of different kinds of cactus – of course. I tend to look for cactus that have something a little different: bigger spines or spines in an interesting pattern, colored fruit or spines…or outer flesh that is not green at all. I like the landscapes of different kinds of cactus growing on hillsides.

 There is a hummingbird aviary and hummingbirds outside too.

There was an Anna’s hummingbird at a feeder that moved slightly and the color of the head changed completely. Hummingbirds have prism-like cells within the top layers of feathers on their heads…and the color we perceive varies based on the refraction from those prism-like cells.

Some other birds that we saw:a female Gila Woodpecker (since it did not have any red on its head)

And male Gambel’s Quail.

There were a few plants that were blooming. I didn’t notice the aphids on the close-up I took of one small flower until I looked at the image on my computer monitor!

And then there are rocks…some with brilliant colors

And some just a collection of small stones between plants

And an outcrop on a hillside – red with its iron.

Tomorrow I’ll write a second post about the Raptor Free Flight programs we saw on our visit to this museum last month.

Saguaro National Park – Rincon Mountain Distract

Our January visit to Tucson included a morning drive in Saguaro National Park – Rincon Mountain District. It was quite different than the last time we visited in June 2013. It was too early for the desert spoons or saguaro cactus to bloom although the cholla provided some rosy/orange color to the landscape.

Here is a close up of the cholla – the brightest colors of the winter landscape.

I like the whites and greens of some of the plants of the desert…but these leaves are not for touching any more than the cactus with their spines.

There was snow on the peaks of the Catalina Mountains to the north. The ocotillos looked like gray thorn sticks; some had a few remnants of last year’s seeds. In a few months the ocotillos would be green thorn sticks with orangey red blooms at their tips.

The visitor center is low and has enough vegetation around it to be almost hidden even in this desert landscape. The loop road beings at one end of the parking lot.

I noticed young saguaros with nurse plants still protecting them from the harshest heat and sun.

The accordion pleats of the cactus body are not always as orderly as I’d assumed. Sometimes they need to grow more pleats as they get larger!

The beginnings of the saguaro ‘arms’ almost look like another cactus growing on the main trunk.

The plants on the rocky slope of the Rincons from one of the loop road overlooks have water nearby this time of year – probably from snow that melting higher up in the mountains.

From our vantage point we could not see any snow in the Rincons. Either it had melted or was still on the peaks out of our sight. We think of deserts as having very few plants but this one has quite a few plants…all that survive with very little water as look as they are undisturbed.

Gleanings of the Week Ending February 06, 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.

Tranquil Oil Paintings Reflect Peacefully Ripping Water Scenes – Gives me an idea for a photo project. And this one does too: Seeing the Trees through the Forest: Vestiges of Ancient Woods

7 Easy and Delectable Vegan Quick Breads – Goodies in winter!

Joyful Portraits of Centenarians that are Happy at One Hundred – Hurray! To be happy and 100!

This Is What 17 Different Foods Look like Growing in Their Natural Habitats – All these images are ‘beautiful food’!  The majority of these do no grow in Maryland (except in conservatories)…and I don’t think I’ve ever seen a cashew tree even in a conservatory.

America’s Broadband Improves, Cementing a “Persistent Digital Divide” – Rural areas are still problematic….maybe stratospheric drones and balloons will be deployed.

Why the calorie is broken – It turns out that the concept of ‘a calorie’ is not a clear cut as we expect….that there are lots of ways the amount of energy we get from food can be changed. In general – the processes or cooked a food is, the more energy we get from it!

The Scientific Outreach Gap – This was a study done in the UK but the same is true in the US and it isn’t that the public is not interested. My daughter has volunteers for outreach events for astronomy and astrophysics for the past few years and the events have been well attended – almost overwhelmingly so.

Beyond Half Dome: Five Yosemite Sites – Adding to the places I’d like to go (eventually)

The Mycobiome – There has been a lot of research on the human microbiome but most of it, so far, has been about surveys and studies of bacterial species. There are fungi that are there too…and research about them has just started to appear in papers in the past 5 years.

Evidence-based health care: The care you want, but might not be getting – Yes! This is what I want but it seems very hard to get. The study was specifically about hospital settings but it matches my experience everywhere in the US health system. The survey revealed that things like ‘quality’ and ‘safety’ was at the top of the priority list…but how is that achieved without being ‘evidence based.’  I think what is being measured is not skewed toward the patient but to what is easiest to measure (and that could actually be detrimental to the patient).

Madera Canyon

The drive between The Paton Center for Hummingbirds and Madera Canyon was scenic … through the Santa Rita Mountains. We had visited the canyon back in June 2013 and headed straight for a bird watching area near a gift shop that we had stopped at previously.

I saw a woodpecker as I was getting out of the car…did not manage a good picture…and then did not see it at the feeders at all.

Then again – is this an Arizona woodpecker? They are brown and the female does not have any red at all so I think it is. I didn’t realize what I was getting when I took the picture.

There were squirrels cleaning up the seen under the feeders --- but the feeders are positioned to keep squirrels from getting the seed directly.

There were quite a few Mexican Jays at the feeders

And the nearby trees and railings. Some of the railings have numbers to help people talk to each other about the location of a bird they are pointing out to someone else.

The biggest birds were the Wild Turkeys. They too were under the feeders although the adults spent most of their time parading. Two of the juveniles managed to fly up to the feeders – perch on the roof – and eat the seeds.

There were a few hummingbirds. This is the only one I saw well enough to identify – as an Anna’s Hummingbird.

The Yellow-eyed Juncos were fast but I was patient enough to get one good picture! I had a hard time identifying it as I was writing this post because it is not in All-About-Birds!

Paton Center for Hummingbirds

Tucson Audubon’s Paton Center for Hummingbirds is located just outside of Patagonia, Arizona. January is not the best time to visit but that is when we were in the area. We didn’t see hummingbirds but there were plenty of other birds around although they were in winter plumage – so not very colorful.

There are numerous feeders and benches. The birds are not as wary of people as they are of potential predators. We say a larger bird fly over and all the birds disappeared from the feeders into the brush piles.

There are different kinds of feeders…with different kinds of seed. The feeders for the hummingbirds had no birds around them while we were there but it was a cold morning.

There were tussles at the popular feeders…lots of acrobatics to either keep or find a place at the feeder.

Sometimes it was uncomplicated…with only one bird at a feeder…munching.

This is definitely a place I want to visit again – in another season. If I lived in the area – I’d volunteer to help keep the feeders full. Kudos to the Tucson Audubon Society for acquiring it in early 2014!

Learning Log – January 2016

January was a month of varied learning opportunities.

Udemy. I finished one course: Unearthing the Trojan War: The Life of Heinrich Schliemann

And started another (Photography Masterclass: Your Complete Guide to Photography).

I prefer the Coursera type courses over Udemy. The Udemy courses have less depth and the range of materials is limited to videos (often voice over charts)…without a robust list to references outside the course.

Lecture. I went to a one-hour lecture about Black Bears in Maryland and enjoyed it thoroughly. The presenter had a trunk of materials to pass around. One was a pelt of a largish black bear (obtained from a road kill); it took two people to hold and examine. I realized that I fall back into my long standing habits as a student in the classroom very easily: taking notes to pay attention – it works for me and always has. Now I’m prepared to trivia questions about black bears. Did you know that in the fall bears need to eat at least 20,000 calories per day to prepare for hibernations?

Coursera. I’ve finished 2 weeks of the Soul Beliefs course. This is the first in a series of courses which I will make my way through over the next few months. This is a good time of year to take courses since the weather encourages indoors activities.

Raptor Free Flight. My favorite experiential learning in January was the Raptor Free Flight at the Arizona-Sonora Desert Museum. We saw Harris’s Hawks, a Barn Owl, Chihuahuan Ravens, a Great Horned Owl, and a Prairie Falcon. The Harris’s Hawks live and hunt in small groups; their coordinated efforts while hunting are quite different than the solitary owls and falcon.

Gleanings of the Week Ending January 30, 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.

What will power tomorrow’s spacecraft? – Lots of options – some ready now and others being developed.

Stock Your Pantry with Plant-Based Protein – I’m not as keen on soy products (except for the nuts themselves) but I have most of the rest in my pantry already; they store well and can be easily be used for quick meals.

Tea or coffee: Which drink is better for you? – Does it matter? This analysis says it is a draw. Tea does not interfere as much as coffee with sleep but is does stain tea more.

New Bioplastic Mashup Spells Doom for Petrochemical Industry – DuPont and Archer Daniel Midland join the flurry of activity in the bioplastic arena….and they may be big enough to overcome the entrenched political interests supported by the petroleum industry. It is good to understand that as we move to a more sustainable tech….plastics will still be around.

A natural beauty: American geoheritage – Geoparks (a UNESCO designation) are becoming popular around the world but not in the US because of political differences within our country. There are over 100 areas in 34 countries that are designated as Geoparks at this point. Over the next year, we’ll be hearing more about them culminating in the 2016 Earth Science Week (Oct. 9-15). A list of countries and sites is available here.

So You Want to Eat Snow. Is It Safe? We Asked Scientists – I do enjoy snow ice cream….but I wait until it has snowed for a while before I collect the snow.

20 Indoor Air Pollution Tips – I heard most of these before….but it is good to see them collected into a single list. I’m glad they included scented products and sprays on the list.

Women Asked to Avoid Pregnancy as Zika Epidemic Worsens – A story to follow since the mosquitos that carry the virus are relatively widespread….it is just that they are not infected with the Zika virus yet in the US. Asking a population to avoid pregnancy is not a solution…but 3,500 (and probably growing) cases of microcephaly will impact lives and economies for years to come.

8 Great Benefits of Walking – A good list with links to the research that backs up the claims.

Best Things about Electric Cars – Results of a survey of electric car owners.

Tucson Botanical Garden

We visited the Tucson Botanical Garden back in January 2015 (did three posts about it: butterflies, garden and poison dart frogs. There is a new building that is the garden entrance and gift shop – with a lot more room than the older structure that was originally a house. We knew about the butterfly exhibit from last year and headed for that as soon as it was open since the air temperature was still pretty cool outside. Inside the greenhouse it was steamy and warm. I enjoyed the orchids and other tropical plants.

There were fewer butterflies than last year but one sat on my husband’s hat for a very long time. Can you see the curled proboscis?

Another sat high on some foliage and posed with wings wide open. The markings make the upper wing look pleated.

I only saw one poison dart frog and did not get a good picture. Disappointing. But….the docent told me that they have tadpoles; if they are successful raising them the population will be larger next year. The poison dart frog live multiple years and were originally brought to the butterfly house to eat fruit flies attracted to the fruit put out for the butterflies.

Outdoors, I noticed better signage this year for birds, lizards, and material for basket making. The signage is tile or protected by glass to survive the very hot temperatures of Tucson in the summer.

I saw a tiled bench with a pomegranate motif

And then the plant itself!

Arizona is famous for its geology and its deserts so I took a number of rocks/minerals along with desert plants.

Some of the colorful rocks look like they’ve been painted but the crystals of the mineral are often visible!

There were two special cactus images this time: a colorful one

And a dead one (for some reason – the curves in this piece of cactus stem appealed to me…maybe I should use it as a starting point for a Zentangle pattern).

Ten Days of Little Celebrations – January 2016

I enjoy the big celebrations of the year....but the little celebrations that happen daily are the ones that keep me going all year long. Here are my top 10 for January 2016:

The most recent celebrations have to do with snow:

• Getting home from the airport in the ice and snow (it had just started coming down…so nothing had been treated yet)
• A snow big enough to cover everything and close just about everything – snow days and snow ice cream

I travelled to Tucson, Arizona this month and about half the celebrations are associated with that trip (and I still have a lot of posts in the works about that travel):

• Birds of southern Arizona (hummingbirds and turkeys!)
• Mount Lemmon (snow at the top)
• Arizona-Sonora Desert Museum (plants and free flight raptor programs)
• Tohono Chul (steps to the roof as plant stand, rocks, small meditation garden)
• Tucson Botanical Garden (butterfly exhibit…cactus…rocks)

January 2016 included my 43^rd wedding anniversary....maybe that should be a ‘big’ celebration!

There was also a funeral in the family this month – a sad event but also a celebration of a person’s life and of continuity of family over long periods of time.

And last but not least, I spent more than a third of the month away from home ---- so it was a celebration just coming home again (in time for the big snow).

Intimate Landscapes – January 2016

This is the fourth month for my Intimate Landscapes series (after reading Eliot Porter’s Intimate Landscapes book (available online here)) featuring images from January that are: smaller scale but not macro, multiple species, and artsy.

There is only one picture from Maryland this month – the frozen edge of a stream with pebbles showing, dark leaves caught on the surface, green and brown plants around the edge.

All the other images are from Arizona this month…I’ve saving the wintery ones for February since I had so much to share from Arizona. The colors are often subdued- the greens of saguaro and desert brush, the browns of twists of dead wood and occasional water, the whites of rocks.

And then there are sudden bursts of color that draw the eye – oranges…and yellows.

I made a slide show of the other intimate landscapes that appealed to be in Tucson – a vine growing on a purple wall, the color variation in prickly pear, a lone flower in front of a white wall, a very small cactus surrounded by black rocks and fallen leaves from its nurse tree that shades it during the hottest part of the summer, small saguaro getting big enough to show among the palo verde and cholla, groupings of cactus with colorful spines, young saguaros lined up in rows between lighter leaved plants and yellow flowers with palo verde in the background….such are the intimate landscapes around Tucson.

Gleanings of the Week Ending January 23, 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.

Breakthrough discovery reveals how thirsty trees pull water to their canopies – It is cohesion and gravity rather than atmospheric pressure that is the driving principle. I always thought it was due to ‘capillary action’ but that term is not mentioned in the article at all.

Giant Clams Light Up Like Plasma Screens, Only Better – Potential for organic displays…..using the giant clam mechanism for power and color.

Photography in The Parks: Accessible Zion Through the Seasons – Nice to know that Zion has something for everybody. I missed it a few years ago when the government was shut down while I was in the area….want to try again.

How do birds stay warm on a cold winter’s night? – Huddling together seems to be popular. The article suggests providing nesting boxes to help the birds find a good place just after sunset. And another post about birds - Snow birds: 10 birds to look for in winter. The feeders at Sapsucker Woods (Ithaca, NY) have a camera on them; the video feed is here. The birds in this post are not what is visiting my feeder and bird bath right now; I’m seeing cardinals, juncos, blue jays, and doves almost every day.

Scientific Illustrator Hand-Paints Giant Mural Featuring 243 Modern Bird Families – Next time I am in Ithaca NY (Cornell University) – I’ll want to see the mural.

Infographic Offers a Valuable Guide to Feeling Happier in Your Life – Lots of variables…and this is all a matter of statistics. There are happy people that don’t meet all these….and the genetics part is something we can’t change anyway! Another perspective on the same topic from BBC Futures: A 7-day guide to the pursuit of happiness.

Arthropods Abundant in American Homes – The average US household contains 62 distinct families of arthropod species. They range from cockroaches and fleas to carpet beetles and book lice…ants. They are our (mostly) quiet and benign roommates.

Why do we get ‘eye floaters’? – Many people notice them…but they impact vision in very few cases. They are causes when small debris gets into the vitreous humor – the jelly like mass between the retina and the lens in our eyes….that is not replenished or replaced.

The Chemistry of Bread Making – A graphic from Compound Interest.

Tucson Mountain Park Sunset

We managed to get to our favorite sunset location twice during our recent trip to Tucson: Gates Pass in Tucson Mountain Park. The first time we managed to get there just as the sun was going down – got the last parking spot with no time for set up. I still managed some reasonable pictures of the west horizon,

The light reflected off the mountain to the north east almost behind me, and

Then, as the sky darkened, some saguaro on a mountain in the foreground silhouetted by the fading color.

Five days later – the evening before we were flying home – we tried again. We got to the location early enough but the clouds were thick enough at the horizon that we didn’t see much at the time the sun was supposed to be setting.

Then the show started. The lower the sun got, the more the sky filled with color.

At first it was a haze of pink

Then the color intensified.

What a colorful crescendo to our last day in Tucson!
