Gleanings of the Week Ending July 26, 2014

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.

More Phones, Fewer Doctors - An interview with venture capitalist Vinod Khosla about trends in health care. His contention is that 80 percent of what doctors do can be replaced by machines. This article was part of a series done by MIT Technology Review about our health care system. Another one talks about Big Data Mining (about medical analytics).

DIY, Zero-energy Pool Warmers Could Save You Thousands - Made with hula hoops and polyethylene film!

Study reveals 'unhappiest' cities in the U.S. - The authors of the study emphasize that it is obvious that people care about other things that ‘happiness’ when making decisions about where they will live! I’m always a little suspicious of ratings that focus on only one aspect (like happiness/unhappiness) because most of our decision making is much more complex than that. Still - it is worth staring at the map for a few minutes. Does your perception of where you live match with the color coding?

STEM Graduates Branch Out - Many of college graduates with STEM degrees are not working in jobs that are science or technology related fields according to a report from the Census Bureau.

Fluoride & Water Fluoridation – An Undeserved Reputation? - Infographic from Andy Brunning - a chemistry teacher in the UK

Cursed Warship Revealed With Treasure Onboard - A ship sunk off the Swedish coast in 1564…complete with silver and gold coins and canons.

To Measure Summer Smog, Plant an Ozone Garden - The National Center for Atmospheric Research (NCAR) in Boulder CA has designed a garden that is sensitive to ozone that includes plants that grow easily in many parts of the US: milkweed, snap bean, potato, and cutleaf coneflower.

Pangolins Walk Just Like T. Rex - Scaly anteaters wall on 2 legs! Watch the video of this odd animal and think about T. Rex depictions. The head of the T. Rex was much larger but the using tail as a balance to the upper body to allow ‘walking’ on the hind legs like the pangolin is a possibility.

The bend in the Appalachian mountain chain is finally explained - The Appalachians slant along the east coast - make a bend in Pennsylvania and New York.

What vacation? Expect to work while you're away - The down side of mobile work environments.

Celebrating Bugs!

Sometimes bugs can be annoying…but they are often intriguing to watch.

Sometimes they are relatively still. Maybe it is a little cool or they are waiting for prey.

The bugs that are loving my zucchini plants way too much are annoying but have a certain beauty as they proliferate and march over the leaves. Note the size variation in this group!

Some bugs are noticeable by the way they move. Water striders sit quietly on the top of the water…only noticed when they suddenly move.

The pollinators are busy on the flowers.

Some bugs are busy creating the next generation.

Spiders are easily disturbed. This one scurried up one of the securing silks of his web to the pipe when I got a little to close trying to take his picture!

The cicada was a little confused. It was on the ground and allowed itself to be gently picked up….eventually flying backup into the trees.

Gleanings of the Week Ending July 19, 2014

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.

Two articles related to elephants caught my eye this past week: Does this trunk make me look fat?  about overweight zoo elephants and Short lives, violent deaths about the findings from the CT scans of the remains of 2 Siberian mammoth calves (one was 30-35 days old and the other was 52-57 days old).

Icelanders Grieve for the Peculiar Lake Balls - Lake Myvatn used to have balls of algae all over its bottom. Now the lake is full of algae-smothering sediment after mining operations dumped extra phosphorous and nitrogen into the lake cause dense bacteria blooms. There are a few other places in the world where the balls of algae form but one is gone.

NIH Senior Health - NIH has a web site specifically for health and wellness information for older adults!

Longhorns on the Prairie - Not cattle….beetles!

Journey Underground to These Eye-Poppingly Incredible Old Mines - The images look like science fiction (dystopian). Many appear to be open for tourists.

Exploring the Parks: New River Gorge National River - Looks like a beautiful place in West Virginia. I’m putting the link on my ‘vacation planning list!

One injection stops diabetes in its tracks: Treatment reverses symptoms of type 2 diabetes in mice without side effects - Lots of research to come on this. Too good to be true for humans?

14 Fun Facts about Piranhas - From Smithsonian.com. Somehow these fish rank right up there with sharks as ‘scary things in the water.’

Contributing factors to groundwater table declines identified - The article includes color coded maps of Texas from the 1930s to 2000s and shows how much deeper one has to look these days to find groundwater in the state. The declines are mostly due to irrigation and population growth….but there are other factors too. The population of the state is expected to double by 2060 while the water supply is expected to decline by 10%.  Something has to change (probably more than a single thing)!

The Soil Pollution Crisis in China: A Cleanup Presents Daunting Challenge - Third and final of a series. The links for the other two articles in the series are at the bottom of this final article. Scary stuff. With population growth, it is tragic to damage farmland. 

Zooming - July 2014

We are in the full swing of summer - lotus and water lilies - summer wild flowers and fireworks. Those are major themes for the zoom collages this month. 

The first collage is of lotus at the Kenilworth Park and Aquatic Gardens.

The water lilies are also from Kenilworth.

The squiggles from botched firework pictures actually turned out to be worth a collage too.

Last, but not least, a zooming collage from my walk around the Howard County Conservancy Honor Garden.

Gleanings of the Week Ending July 12, 2014

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 baby names spread across the US - interactive map - What fun! The map is set with a search box (enter a name) and then the historical preference for that name by state begins to play.  Some names spike and then ebb….others stay about constant.

Geothermal Heat Melting Road Surface of Firehole Lake Drive in Yellowstone National Park - Wow! I’m sure we probably drove this rode when we vacationed in Yellowstone. Hope they can figure out how to fix the road.

Fossil Interests Attack Clean Energy Politics: State-By-State Map - The ‘fossil interests’ would be appreciated more for delivering quality in their own products (reducing costs, reducing or eliminating environmentally damaging byproducts, etc.) than when they attempt to trash their competition.  American consumers are getting savvier all the time about how energy costs come about.

Rewriting the history of volcanic forcing during the past 2,000 years - New data from detailed analysis of Antarctica ice cores about volcanic sulfate emissions in the Southern Hemisphere over the past 2000 years is feeding into climate module simulations. The research was done with 26 cores from 19 sites and has taken more than a decade of collaborative ice core collection.

The Alien Brains Living on Planet Earth - Learn something new…about octopi.

Never-Before-Seen Photo of Europa Shows Rivers of Red Ice - A natural wonder than could pass for a work of art!

Babies born to healthy moms worldwide are strikingly similar in size - Focusing on baby born to health, well-educated and well-nourished mothers….this was a large study too: 60,000 pregnancies from 8 urban areas around the world (Brazil, China, India, Italy, Kenya, Oman, the UK, and the US).

Made from History - A site started in May 2014 that collects and organizes historical materials. The main collection areas are World War I, World War II and Civil Rights but there is a search capability as well. I did a search for ‘Little Bighorn’ and article called ‘The Top 7 Military Mistakes in History’ was the result.

Radio-burst discovery deepens astrophysics mystery - There is still a lot to learn about the universe….in this case, the new data confirms observations from the Parkes radio telescope in Australia (there had been speculation that it was a fluke of the Parkes instrument rather than an actual observation prior to this new observation from Arecibo).

Mutations Pervade Mitochondrial DNA - More than 500 point mutations in mtDNA have been implicated in diseases….and there may be a linkage to aging as well. This is deservedly a hot area for further research.

Water Lilies at Kenilworth Aquatic Gardens

I’ve posed previously about the lotuses, dragonflies, and a Great Blue Heron at the Kenilworth Park & Aquatic Gardens. Today’s post is focused on water lilies.

There are far fewer varieties that when the gardens were a commercial concern in the early decades of the 1900s, but the ones that remain are still beautiful. The storm had caused some damage to the lily pads but not as much as the lotuses experienced; there is an advantage for not being as far out of the water.

I found myself trying to capture images of dragonflies and bees on the flowers…..and trying to capture all the different colors. I picked the best images I captured for the slideshow below.

And I can’t resist included this golden dragonfly. It seemed different than any of the others.

Heron in the Lotus Pond

Yesterday we made another trip to the Kenilworth Park and Aquatic Gardens in Washington DC. There were still a lot of lotuses in bloom but the storm mid-week had snapped some of the leaves, buds and flowers. I enjoyed taking pictures of lotuses and dragonflies again then focused on water lilies (the topic of post to come) but the high point of the outing was a Great Blue Heron. The water level in one of the ponds was low and the bird was taking advantage of the easy pickings. There were people taking pictures of the heron all around the pond; the heron was too focused on food to notice.

As we walked up - the heron caught a fish. My husband captured the image below with the catch before the heron flipped the fish and swallowed!

Enjoy the best of the rest in the slideshow below!

Dragonflies at Kenilworth Aquatic Gardens

The lotuses are blooming profusely at the Kenilworth Park & Aquatic Gardens in Washington DC; I’ll post about them later this week. The dragonflies are the focus for today. There were so many of them when we were walking around the ponds yesterday that I managed to capture quite a few images. They like to perch on dried seed pods,

Folded lotus leaves and

The tips of lotus buds.

The sun reflects off their wings giving them a metallic gleam.

Sometimes their color is jewel like: powder blue, deep green, black veined gossamer.

Sometimes their thorax looks muscle bound

And sometimes it looks it has sub-segments.

This one has droopy wings.

This last picture is my favorite - the color of the uncurling lotus and the dragonfly perching for a few seconds before flying out again over the water.

A Picnic at Howard County Conservancy

The weather was perfect for the Fiddlers and Fireflies event at the Howard County Conservancy this past week.  I took an eclectic picnic: frozen blueberries, spinach salad with bacon bits, Fruit Beety under a layer of plain yogurt (a mini-parfait), and collard green chips.

I enjoyed walking around the picnic area and Honors Garden taking pictures. The bees were very active and - grateful that cameras are digital these days - I took a lot of images and picked 3 for this post.

And now enjoy the rest of the best from my after picnic walk in the slide show below!

Gleanings of the Week Ending June 28, 2014

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.

Enjoy the Wilderness of Saguaro National Park through This Video - I’m remembering the vacation to Tucson last June --- which included a morning at this National Park. Another blurb in the feeds this week about one of my favorite places: Longwood Gardens Unveils 86-acre Meadow. I’m already beginning to think about return visits!

Timeline of Emerging Science & Technology (2014 to 2030+) - From Richard Watson and the Imperial College of London. If you want to look at an enlarged version of the graphic - a PDF is available here. One of my favorite technologies is autonomous cars - and there was a new item on that topic this week too: Demonstrating a driverless future: Promise of driverless cars. Computerworld posted 8 technologies that are on the way out - and one that we’ll never be rid of.

Reproduction later in life is a marker for longevity in women - Hurray! I fit this marker for longevity in women (I was 35 years old!).

Connectivity is Critical: 33 Ways Broadband Boosts Learning - There are lots of positives about connectivity but it takes a level of maturity to not experience the negatives. Like most technology - advocates think only of the positives first; hopefully eventually there are objective perspectives.

Architecture of signaling proteins enhances knowledge of key receptors - The Preventing Chronic Pain course I am taking was focused on the systems biology aspects of pain last week - so I noticed this article more than I might have otherwise. The progress being made in the systems biology arena is gaining momentum now that the technology is available to research questions.  Another systems biology type article: about creating viruses that naturally home in on tumor cells while boosting the body’s immune system was posted by The Scientist.

Interactive Model Skeletons - Free Technology for Teachers has a blurb this week about eSkeletons, from the Department of Anthropology at the University of Texas. The site is focused on primates. What a wonderful way to learn about skeletons!

Mysterious 'magic island' appears on Saturn's moon Titan - Something new on Cassini’s mission radar of Ligeia Mare…a ‘transient feature.’

Do the Rumble-Rump with Peacock Spiders - I’d seen pictures of these spiders before but had not realized how small they are….and the videos (here) are worth a look too!

Few Doctors Warn Expectant Mothers about Environmental Hazards - I hope this change.

Distributed Renewable Energy under Fire - How electric utilities are fighting local renewable energy in 19 states. It’s a frustrating situation. I’m glad Maryland is not one of the 19.

Aargh! Deer ate the Day Lilies

A few days ago the flower bed of day lilies was full of potential. A few buds had opened but there were a large number of buds that were still forming.

Yesterday I discovered the devastation caused by browsing deer. The part of the flower bed I had photographed on the 18th still had a few buds; probably about half of them had been eaten. Maybe something has caused the deer to hurry away because the other end of the flower bed had almost no buds! I’ve circled the nipped stalks in the image below. Aargh!

I’ve learned my lesson….I’ll be spraying the liquid deer fence every week; it had worked well during the spring when I had sprayed regularly but I had stopped - thinking the deer now had a lot of other food around. I hope that somehow the lilies recover enough to produce a new crop of flowers if I keep the deer away.

3 Free eBooks - June 2014

It’s time again for the monthly post about eBooks that are freely available on the Internet. The three below are my favorites for June 2014.

Birds, Illustrated by color photography. Chicago: Nature Publishing Company. 1897. Fourteen volumes are available from Project Gutenberg here. The image of the kingfisher is from volume 1, no. 2.  I am slowly working my way through all the volumes. I’ve enjoyed the first 4 so far.

Cailliaud, Frederic. Voyage a Meroe. Paris: L’Imprimerie Royale. 1826. Two atlas volumes are available from the Internet Archive: volume 1 and volume 2. I just finished a Coursera course on The Art and Archeology…and was thrilled to find these books online. They have drawings of some things that have been degraded between 1826 and not - either through simple ravages of time or rising water from dams built on the Nile.

Versailles et les Trianons : vues photographiques. Versailles: Moreau. 1880. Available from the Internet Archive here. It’s been a draw for tourists for a long time….and people bought souvenirs in the 1880s like this book!

Gleanings of the Week Ending June 14, 2014

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.

10 Top National Wildlife Refuges to Explore - I’ve only been to 2 of the 10 (Chincoteague and Wichita Mountains but I’ll take the opportunity to see more if I am in the area of these. I was surprised that Merritt Island (Florida) did not make the top 10.

The Sleep Schedules of Some of History's Greatest Minds - I was surprised at how many are on a 10PM to 5 or 6 AM schedule (which is similar to what seems to work best for me!)

The 10 Cutest Animal Flash Mobs in the World - The hummingbird video (#6 on the list has music to enjoy while you watch the hummingbirds getting fuel for migration. It’s a strangely relaxing frenzy!

The Finest Examples of Art Nouveau Architecture in Central Europe - I am more interesting in architecture since I took the Roman Architecture course last spring.

Articles that appeared recently about two of my favorite places: Mesa Verde National Park and Chaco Culture National Historical Park

Road Salt Creating Beefier Butterflies - A little extra salt causes developmental changes (and they are different for male and female Monarch butterflies) that could be beneficial….and then at some point the extra salt becomes toxic.

Company man or family man? Fatherhood and identity in the office - Research published just in time for Father’s Day.

Common heart drug's link to diabetes uncovered by researchers - The study found that statins can activate an immune response that stopped insulin from doing its job properly….and that taking Glyburide suppressed the side effect. It is a bad thing to take a drug that then requires us to take another drug. How do we determine when the bad side effects multiply beyond the benefits of the cocktail?

Most comprehensive 'world map of research' yet: Researchers analyze 15 million scientific articles - Articles used from the analysis were published from 1996-2006. There are three clusters of countries: biomedical, basic science and agriculture/fisheries. The US is in the biomedical cluster, Singapore and Japan are in basic science and most of the developing nations are in agriculture/fisheries.

Fruits, Vegetables, and Disease Risk - Which vegetables are the most nutrient rich? This article points to a recently released report that include a list (available here).

Bees

There seems to be a bumblebee that enjoys hovering outside the window I prefer to settle into for reading. There are not any flowers more than a story off the ground so the hovering does not last long but I’m surprised at the number of times there is a bee there.

Today I am celebrating bees photographed this spring: on snapdragons at Longwood gardens,

On wisteria at Brookside Gardens, and

On honey suckle at Watkins Glen State Park.

While I was looking for bee pictures in my recent photographs I found a picture of a small wasp on maple flowers from back in April  (this was photographed with the 8x loupe…on a cold day when the wasp was not very active). It doesn’t belong in a ‘bee’ post but I couldn’t resist including it. I enjoy the serendipity of photographing something like this….and the red color of the maple flowers is one of my favorite signs of spring.

Gleanings of the Week Ending June 7, 2014

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.

Now that I am taking an Exoplanets on Coursera, I am noticing a lot of articles in my news feeds about them: 'Neapolitan' exoplanets come in three flavors, Astronomers discover two new worlds orbiting ancient star next door: One may be warm enough to have liquid water, First light for SPHERE exoplanet imager: Revolutionary new VLT instrument installed, Astronomers find a new type of planet: The 'mega-Earth', Diamond planets may be more common than astronomers thought, Super Earths Found Circling Ancient Star, Harsh space weather may doom potential life on red-dwarf planets, and The Closest Known Potentially Habitable Planet Is 13 Light-Years Away

Exploring the Parks: Musings from El Morro National Monument - Always a nice reminder to see a story about a place I’ve been and enjoyed!

Hundreds of "Hidden" Paintings Discovered at Angkor Wat - Using de-correlation stretch analysis on walls with traces of pigments.

Is the food industry really concerned with obesity? If people eat less, profits will decline - Consumers have to be savvy enough to see the healthy food that gets shifted to the background by marketing of (mostly unhealthy) processed foods.

Are your pets disturbing your sleep? You’re not alone - We have two cats. I ignore them during the night and early morning but my husband responds to their nudges to be scratched…..and so they now ask for more scratches during the night (my husband reports this while I sleep through it all)!

New Desalination Technologies Spur Growth in Recycling Water - Desalination is not just for seawater. The technology is also important for reusing agricultural water and industrial effluent.

Views of Venice - Art Added to Street View Imagery of Venice - This article is on a ‘tools for teachers’ site but the visuals over the google street view are fun for everyone. Visit the site and click on the ‘menu’ button in the upper right to see the art work that can be overlaid of the street view.

Wind Turbines and Birds: What’s the Real Story? - Bats are impacted too. The key question still seems to be - how can we develop wind turbines that avoid the negative impacts to biodiversity (and avian/bat mortality).

A Complete Primer for All the Species of Cats - A collection of a series of posts about species of wild cats.

New health services needed for rise in 100-year-olds - With more people living to 100 years and beyond - the need to hone health services(particularly palliative care) for them is becoming more important.

Tree Trimming

A recent rain weighed down the plum tree branches enough to convince me it was time to trim the tree. I got out a step stool, the saw, and the long handled pruners. I cut off low branches and ones that were growing more horizontal that vertical. Afterwards I took a closer look at the layers within the branches - the delicate color changes from the bark to the sapwood (cambium, xylem), and then the heartwood.

Next up on my ‘to trim’ list was the oak. Oaks do a lot of self-pruning so the main work I do on the treat the edge of our yard near the street is focused on the lower branches when they grow low enough to brush the tops of vehicles in the street or our car as we pull into the driveway. It was harder work than the plum tree; the branches were larger and a bit higher too. There were many tiny acorns on the branches.

I also found an oak marble - almost a ‘glow in the dark’ green.

I cut open the shell and found the insect larvae suspended inside the sphere.

The branches were quite lot and I wove them into the brush ‘fence’ around my chaos garden….more about that in another post.

Watkins Glen State Park in the Spring

Watkins Glen State Park is a gorge with many waterfalls. The main entrance is at the bottom of the gorge but there is another at the top. Either way the gorge trail has stairs and wet stones/pavement. The last time we were there was in fall 2012 - when there was a lot of color from leaves. In the spring - there is a lot of green to contrast with the stone and quite a bit more water.

The gorge trail is a ledge. In one place it goes behind a waterfall.  There are frequently water droplets from overhanging rock. I was glad I had remembered to wear a hat. Waterproof shoes are good too if the day is cool (and wet feet would be uncomfortable). I made a slide show from my favorite gorge images from last week.

While my husband focused on his own photography projects - I managed to photograph a crow

A busy bumble bee

And a tiny fern unfurling its fiddleheads.

Coursera Experience - June 2014

May was a relatively easy month from a course load perspective. I finished two courses:

• The Emergence of the Modern Middle East (Tel Aviv University) - I was surprised at how little I understood of even the events that have occurred in my lifetime. I generally keep up with news but I clearly needed more context than the news stories provided…..or maybe the passage of time has brought enlarged perspective of historians.
• Introduction to Systems Biology (Icahn School of Medicine at Mount Sinai) - Probably the hardest course I’ve taken on Coursera so far.

And only had one that continued on for the full month.

• The Art and Archaeology of Ancient Nubia (Emory University) - This one has short videos and then pointers to reading. I am supplementing the recommended reading with items from the Internet Archive and some books I got via paperbackswap. This one will be over by the end of June - which is a good think because I have so many more that are starting!

There were two that started right at the end of May.

• The Diversity of Exoplants (University of Geneva) - I am taking this course to understand more about what my daughter’s research is all about in graduate school.
• Preventing Chronic Pain: A Human Systems Approach (University of Minnesota) - I am fortunate to not currently have chronic pain….but prevention is always easier than recovery. And there are others in my family that do have challenges caused by pain.

The challenge increases in June as three more courses start up. There are just so many good courses being offered that I can’t seem to resist.

• Paradoxes of War (Princeton University) - Every course I have taken from Princeton has been excellent….and I’m looking forward to this one.
• An Introduction to Global Health (University of Copenhagen) - This course and the next one on the list are part of my trend to think more globally about issues. There seem to be so many areas that transcend the boundaries of nations and governments.
• Globalization and You (University of Washington) - It will be interesting to find out how this course meshes with the one on Global Health.

It’s going to be quite a course load by the end of June!

Gleanings of the Week Ending May 31, 2014

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.

Two items from National Parks Traveler of places I enjoy: Protecting the Saguaro Wilderness and Essential Summer Guide '14: Looking for Ponies at Assateague Island National Seashore.

Quinoa Cakes - The recipe has so many good things in it. I think I’ll try it!

The Metropolitan Museum of Art Releases 400,000 Hi-Res Images Online to the Public - Wow! Read this article then take a look at the site here….prepare to spend to some browsing.

Melatonin makes old bones stronger - This was a study using rats…so it may not be true for humans…but wouldn’t it be great if it was. Better sleep and better bones via melatonin!

An Interactive Chart of Which Jobs your College Degree Actually Gets - This is a complex graphic. If you really want to look at particular items - go to the interactive version on the creator’s website here.

From chaos to order: How ants optimize food search - Translating observations into a mathematical model that seems to apply to other animals too.

Saturn’s Icy Moon Harbors Ocean - Liquid water exists beneath the icy surface of Enceladus at its south pole…..and that implies the potential for extraterrestrial life there too.

New data show how U.S. states are doing in science - 59 indicators (like state performance in education, the scientific workforce and high-tech business). The article is about the site that provides access to all the data and several ways to visualize it (here).

How Wind and Water Create The World's Most Beautiful Rock Landscapes - The images in the article and the comments are worth taking a look at this link even if you are not interested in how they get created!

Road Trip - Columbia MD to Corning NY

Earlier this week we started our short vacation to the area around Corning NY. It’s an area we have visited more than a handful of times over the past 25 years. The route takes us around Baltimore and heading to York and then Harrisburg Pennsylvania. The Welcome Center as we passed into Pennsylvania has a wonderful display of irises. I remembered that they looked just a gorgeous as the year we drove up for my daughter’s college graduation - about this same time of year. What was different about the rest stop this year was the milkweed coming up in many of the beds; the shoots were so dense that it has to be planted intentionally. Hurray for the state of helping out the Monarch butterflies!

After Harrisburg the route heads toward Williamsport. It follows a very scenic stretch of the Susquehanna. It is possible to catch glimpses of the river. Many of the islands have been designated Wildlife Management Areas. We noticed this time that US 15 has signs that say ‘Future Corridor of I99.’

The stretch of road through the Allegheny’s - where clouds frequently kiss the rounded mountain tops on either side of the highway - is very scenic but there are no rest stops and very few places to find something to eat!

We made such good time that we rolled into Corning early enough that we forged ahead to take a look at Watkins Glen State Park. More about that in a few days….and Montour Falls….and Letchworth State Park.  It was a waterfall extravaganza!
