Gleanings of the Week Ending October 22, 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.

Invisible Details of Tiny Creatures Uncovered with Laser-Microscope Photos – Details of small creatures…how much of the world we miss entirely if we look only with our un-aided eyes.

What do Americans fear? – Evidently this is the third annual Survey of American Fears from Chapman University.

Obituary for the 25-million-year-old Great Barrier Reef – Another way to think about our impact on Earth.

Sweet Science of Honey – Did you know that honey is anti-microbial and it fights bacteria on multiple levels? So far, honey has not been shown to contribute to resistance either.

Hypothyroidism symptoms linger despite medication use, normal blood tests – A study that shows that not everyone gets symptom relief from the current standard treatment with levothyroxine…and that the medical community is finally beginning to notice.

10 Great Butternut Squash Recipes for Fall and Winter – I like butternut squash so I am always on the lookout for good recipes. Most of the time butternut squash, pumpkin and sweet potatoes can be substituted for each other in recipes too!

Cicada wings inspire antireflective surfaces – Another example of getting materials engineering ideas from nature.

Skip the Math: Researchers Paint Pictures of Health Benefits and Risks – It’s hard to understand the trade-offs involved in many tests and medicines. I was glad to see this attempt --- and hope that doctors become more savvy too.

Calcium supplements may damage the heart – There are growing concerns about potential harms of supplements…and this study about calcium is one example of studies behind that growing concern. The analysis of 10 years of medical tests on more than 2,700 people revealed that while a diet rich in calcium is protective…taking calcium supplements may increase the risk of plaque buildup in arteries and hear damage!

Why sentient tools will be catastrophic to the job market – Sentient tools (example: autonomous cars, warehouse workers, delivery people) are not as ‘sci-fi’ as they used to be. We see early examples of many of them. They will become increasingly able to outperform humans in a variety of jobs. Think of the ripple effect of autonomous cars – on insurance company revenues, on emergency services, on taxi drivers!

Zooming on Insects

The last week or so has been a great time for photographing insects. There were skippers enjoying some last season Joe Pye Weed at Centennial Park. I took pictures at different angles and discovered when I got home that there might have been two different types of skippers on the plants.

At home, I checked the milkweeds for insects and could find any adult milkweed bugs like I found a few weeks ago but there are some larval stage milkweed bugs. They develop so quickly that there are at least two stages in this one grouping…maybe three.

On another milkweed there are aphids – again. There must have been something that came and cleaned off a lot of the aphids, but they are back now. Again – there are multiple stages of aphids in this one picture with the whitish ones being the youngest and then look at the different sizes of the yellow ones.

There was a very small insect with a green metallic-looking thorax. Sometimes insects look like little machines.

And a fly on the milkweed – with bristles on the abdomen!

As you can tell – I am having a lot of fun right now using the zoom (optical + digital) in my camera! There is a lot to see out there.

Gleanings of the Week Ending August 6, 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.

Kathleen Clemons Instagram – Instructor for some of my favorite Creative Live classes….sharing photos taken with her iPhone. Beautiful images…mostly flowers.

Milkweed Meadow posts from What’s That Bug? – A cluster of milkweed plants is a great place to look if you want to find insects. This series of blog posts is focused on typical insects you’ll find.

How to Prevent Mosquito Bites – I am paying more attention to articles like this since Florida is reporting more Zika cases…and I’m planning a trip to Florida this fall.

Did We Used to Have Two Sleeps Rather Than One? Should We Again? – Maybe we were not meant to sleep all the way through the night!

The New Green Grid: Utilities Deploy ‘Virtual Power Plants’ – Sprawling networks of independent batteries, solar panels, and energy efficient buildings tied together and remotely controlled by software and data systems….a trend boosted by California’s natural gas shortfall that will become the norm?

Third Severe Flash Flood Hits Maryland/Delaware – The Ellicott City flash flood on the evening of 7/30 (just a week ago) was close to home…lots of destruction of the history main street.

Mystery Mechanisms – Many drugs appear to work…but we don’t know exactly how they work. This post discusses lithium, acetaminophen, and modafinil.

Why do we get bags under our eyes? – No stunning revelations in this article – but interesting that there are multiple reasons that people get them.

Awesome Video Compares the Size of Different Plants and Stars in the Universe – The video is a sequel to Star Size (and distances) which is also included in the post.

Earth’s ‘Annual Physical’ Lists Symptoms of a Hotter World – State of the Climate in 2015 from NOAA (and internationally peer reviewed). The indicators of a warming planet that are: greenhouse gases highest on record, global surface temperature highest on record, sea surface temperatures highest on record, global upper ocean heat content highest on record, global sea level highest on record, extremes were observed in the water cycle and precipitation. The post includes links to download the report – chapter by chapter.

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.

Microplastics – a cause for concern – Lots of questions…only a few answers. It seems like there have been a lot of articles on the topic recently.

Biodiversity has fallen below ‘safe’ levels – We don’t actually know what the ‘safe’ limit is…but do we want to actually find out when there is no recovery? This report is pointing out that 58% of the world’s land has lost more than 10% of its biodiversity. 10% biodiversity loss is the value that was deemed ‘safe’ limit within which ecological function is relatively unaffected.

Early preschool bedtimes cut risk of obesity later on – Another good reason for preschoolers to be regularly tucked into bed by 8 PM!

Electricity generated with water, salt and a 3-atoms-thick membrane –

Splattered Watercolor Paintings Capture the Beautiful Vibrancy of Delicate Flowers – I like just about everything botanical…eye candy too.

Jupiter and Juno – What do we already know about Jupiter’s chemistry? – An infographic from Compound Interest – background for understanding what we already know about Jupiter’s chemistry and what we hope to learn about it from Juno.

From the Earth’s Oceans (images) – From The Scientist. These images reminded me of how different live in the oceans really is than what we experience on land.

Photo of the Week (from The Prairie Ecologist) – Actually – several photos…of little things that thrive in the prairie.

How Type 2 Diabetes Affects the Brain – Two recent studies that have increased our understanding of the cognitive effects of diabetes – refining not only the description of effects but also how the structures of the brain are changed by diabetes.

Yeast emerges as hidden third partner in lichen symbiosis – Wow! This is something I’ll include in my talk with hikers about lichen. They are always fascinated that lichen grows on rocks and tree trunks….that it’s a combination of fungus and algae…and now we can add that there is usually a yeast there too that is often the part producing chemicals to defend the other two organisms in the symbiotic relationship (and sometimes it changes the appears of the lichen too)!

Insects in our Garden

A few days ago was out working in our garden by 7 AM – pulling weeds and cutting spent flower stalks in our flower beds…but I got sidetracked observing insects. The first I noticed were on the skeleton of a milkweed plant. The milkweed tussock caterpillars had eaten all the leaves leaving only the stem and the larger veins of the leaves. They had started crawling over to the bush next to the stem. It seemed like there were hundreds of caterpillars.

After I finished some work, I went inside to clean up and recover from heat. I started wondering if the caterpillars would find the other milkweed plants that were about 5 feet away from the one they had consumed. I went to check at 9 and they had indeed found another plant! I continued to check periodically throughout the day. The gradually spread to 3 more plants. Sometimes they would appear very active and other times they would be resting underneath a leave that was still whole. When they ate, individuals worked on the leaf from the top and the bottom. It was a mass feeding frenzy.

The next surprise came the following morning. I went outside and found that the caterpillars had been active overnight and seemed to be larger. When I went back to check an hour later – more than half of them were not anywhere on the milkweed and I watched as more of them dropped off the plants. It was time for them to go roaming in the leaf litter!

On one of the checks of the caterpillars, I noticed some insects on a blazing start that was in bloom. They were tiny – about a quarter inch. The yellow and black insect is a syrphid or hoverfly.

There were two other insects on the plant but they stayed down in the flowers so much that it was hard to get a good identification.

Maybe some kind of bee?

The two types of insects did interact a little…did not seem to like the other being nearby.

I was very pleased with the performance of my camera (Canon PowerShot SX710HS) and the monopod’s contribution to stabilizing the camera to get clear images.

Gleanings of the Week Ending July 9, 2016

The machines that run the internet – A short film.

A Murder of Crows: When Roosting Crows Come to Town – We don’t have large number of crows in our area – but we are seeing more than we were a few years ago when West Nile Virus killed so many of them.

Picky Eaters: Bumble Bees prefer plans with nutrient-rich pollen – The protein to lipid ratio makes a difference to bumble bees!

Ocean Acidification and Chemical Signaling – How ocean acidification impacts chemical signally of shell fish…an infographic about research on peptides that are involved in detecting predators, homing, and reproduction.

How one of history’s bloodiest wars eventually saved lives – By the end of World War I, combatant deaths has reached 10 million. Twice as many were injured. Post-traumatic stress disorder was recognized for the first time – called ‘shell shock.’ Blood transfusion, oxygen and treatment on the front lines became the norm. See some of the devices developed and used during that time period in this post or at the Wooded exhibition at London’s Science Museum.

Floating Solar: A Win-Win for Drought Stricken Lakes in the US – Will this idea become reality? It seems that in places where water is scarce that reducing evaporation and producing power at the same time would be a positive thing.

Humans artificially drive evolution of new species – Human drive extinction but also speed up evolution of new species as well. For example – a common house mosquito has evolved into a new species that thrives in subterranean environments – like subway stations; it can no longer interbreed with its above ground ancestor species.

Beyond Sightseeing: You’ll Love the Sound of America’s Best Parks – A project to record the (non-human) sounds of national parks.

Boosting potency of broccoli-related compound for age-related macular degeneration – Macular degeneration impacted the last few years of my grandmother’s life and I still notice articles about current research on prevention and/or remediation…. macular degeneration might happen to many of us as we get older.

Vanishing Act: Why Insects are declining and why it matters – Another example of the importance of biodiversity to our future…and the future of the planet.

Zooming – June 2016

My favorite topics for zooming are the usual: birds, plants, and insects! Click on each of the six images to see a larger version. It was hard to top at six collages because there were so many images to clip. After I went overboard early in the week with the Mesa Verde post – I decided that 6 was enough already. The first image includes a house finch, sweet bay, iris, strawberry and peony.

Next comes a monarch butterfly, a poppy, a mourning dove, the center of a flower, and a thistle.

Then allium ball, the back of a flower and another center, and hydrangea growing on a rock wall.

Then an all-insect collage: a dragonfly, a monarch caterpillar, a bumble bee, a black swallowtail caterpillar and two butterflies.

Next is an all plant collage: castor beans, datura, day lily, canna.

Finally – a moth, two pictures of southern magnolia flowers (l like the curves of the petals around the forming seed pods), and an Asian dogwood.
