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.

Sounding Off on Noise – I’ve been thinking a lot more about noise since I started driving an electric vehicle. I notice and enjoy the quiet of the vehicle even though the noise from the well-maintained gasoline powered cars was something I accepted as ‘white noise’ for all the years of my life up to 2017. I would rather hear natural noises (birds singing, wind in the trees) that noise from a highway or airplanes overhead.

Albatrosses counted from space – Even nests inaccessible to humans (on the Chatham Islands off New Zealand) can be seen in satellite images from the WorldView-3 satellite. The numbers of nesting pairs were lower than expected. Several more years of observations will be needed to determine if it is just a poor year or the numbers of birds are indeed declining.

The Nature of Americans: A national initiative to understand and connect Americans and Nature – There is a lot on this site. I started browsing with the Major Findings and then Recommendations. It is well organized and intended to be actionable.

Foods that Lower Cholesterol – No surprises…but the review is good.

Guggenheim Museum Releases over 200 Modern Art Books Online for Free – I am enjoying browsing this collection on the Internet Archive.

Saber-Tooth Cats, Dire Wolves Found in La Brea Tar Pits Show Wounds from Ice Age Battles – Based on analysis of just under 2,000 bones that revealed signs of trauma sustained in combat….events of lives etched in bone.

2-ingredient no-sugar date caramel sauce – Yum! I made this in my small Ninja – very easy and yummy. I’ve used it as a dip for apple slices and spread on toast. A great treat and counts as a fruit and calcium.

Moose hair and birch bark – Taking a close look at an artifact that will go into the Native American Voices gallery at the Penn Museum later this month – after a bit of treatment in The Artifact Lab.

A first-ever find in Egypt: 4,000-year-old funerary garden at tomb entrance – Before now, this type of garden was only known from illustrations on tomb walls.

The secrets of the Coke and Mentos Fountain – A fun experiment….and chemistry lesson.

Our Neighborhood Water Retention Pond

The water retention pond that is supposed to slow down water run-off from our neighborhood was not working and there was flooding occurring with more frequency. Earth moving equipment was brought in by the country and turned a pond with lots of vegetation for wildlife around it (picture from last December)

Into a mud pit with very little vegetation around it. We had a day of heavy rain right after the vegetation was scraped away and the water than accumulated looks thick with silt and has already developed a green scum.

Here it is from a different angle. No one will be sitting on the bench enjoying the antics of red winged blackbirds in the cattails or frogs crocking in the pond anytime soon! One of the neighbors commented that she’d seen a large owl looking at the pond from one of the neighboring houses. It’s likely that it’s home was destroyed. Hopefully, the project will enable the pond to function as it should for water retention. The pond needs some grasses or other vegetation planted on the slopes or this clean out of the pond is going to be short lived.

The only positive thing I saw on my walk around the pond was a single solitary sandpiper. With the heavy vegetation that was around the pond previously, the bird would not have been visible even if it had visited.

On the back side of the pond there is milkweed coming up but the plants are on the edge of the area not previously mowed. Hopefully they will survive for the Monarch Butterflies this season.

Ten Little Celebrations – April 2017

It’s spring…and there is a lot to celebrate.

Second graders coming to Mt. Pleasant for the Science of Soil field trip. I’ve done two file trips for them so far and both have been a lot of fun – using the soil auger in several places while we hike, talking about rocks looking at the old rock wall dividing the fields, seeing how the stream restoration work done during the winter is greening up and full of puddles after a rain.

Azaleas. There are some in our neighborhood but making the trek to the Brighton Dam Azalea Garden is the day we celebrate the profusion of blooms and colors.

Pre-schoolers on a Nature Tales field trip. I’ve done three of the pre-school field trips at Belmont in April: two that were rainy days and one that we made it to the forest. I’m learning how to keep the younger children listening and participating for the whole 20-30 minutes I have them. There are so many little celebrations in every session because the children are so enthralled with the new things they are seeing and doing….I can’t help be celebrate with them.

Delmarva birding. My husband and I spend a day at the Delmarva Birding Weekend late last week. It was our first time to attend and we enjoyed it. I celebrated that there were so many birds to see (and photograph) not that far from where we live. I’ll be posting more about our experience in the coming days.

Faromir. One of our cats died in April. We celebrated his life…and that he was will us for 13.5 years. He was my husband’s little buddy.

Favorite lipstick available again. I’ve always liked Cover Girl Bronze Glow lipstick and was very disappointed when I couldn’t find it anywhere…but now it is back. I celebrated that Cover Girl has started making it again.

Fitting into smaller jeans. I discovered that I can fit into some jeans that I thought were too small. That’s always something I’ll celebrate. I also celebrated that I hadn’t put them in the giveaway pile last fall.

New blade for old paper cutter. I was thrilled to find a new blade for my 20-year-old rotary paper cutter. When I couldn’t find the replacements in a local store and the new cutters did not look at all like mine, I thought I was going to have to buy a new one….but Amazon had the size I needed.

Roman Art and Archaeology course from University of Arizona. I’m not taking as many course from Coursera as I’ve gotten busy with other things…the few I’ve taken recently have been fabulous. I celebrate the availability of the course as the perfect time (the lull before the ramp up of spring field trips) and the well done videos and other references.

Boxes of old documents shredded. We’ve cleaned out some old boxes full of paper (spring cleaning!) and took 2 to be shredded at a local shredding event. I celebrated getting all that old paper with account numbers and social security numbers securely recycled.

The Creamy, Sculpted Dunes of White Sands National Monument – I’ve only been there once…but it was memorable. It was a hot day but the sand is so white that it reflects the sun and can be walked on barefoot! (See my post from back in June 2013 here)

Tracking down water pollution through DNA of algae – A new method for rapid and reliable bioassessment of aquatic environments which will allow for synchronous processing of many samples in record time and reduced cost….no more microscopic identification of organisms in samples!

Circadian Rhythms Influence Treatment Effects – There is a lot of evidence that timing of a medication may have a marked impact on effectiveness….yet drug trails did not track time of day information and thus not on drug labels. Simultaneously – understanding a patient’s circadian rhythm is an aspect of precision medicine - find the right drug for the patient at the right dose… administered at the right time. Also see the infographic: Circadian clock affects heart and disease

How Western Civilization could collapse – Doom and gloom scenarios. Do they seem more likely than they have in recent decades?

What’s chemistry ever done for us? – In infographic from Compound Interest that came out prior to the March for Science last weekend.

Incredible photos of Japan’s natural landscape that look like watercolors – Eye candy….and a little geography too.

4 great things the EPA had done for our health – A lot of progress has been made since 1970 when the EPA was created. No one should want to go back to air so filled with smog that your eyes watered when you went outside (like happened in LA) or lakes became sterile from changing pH or rivers caught on fire.

Foreignceuticals: our drugs go global – Scary. It’s often hard to tell where drugs and supplements come from….and there may be little or no quality control along the way.

Climate change is turning dehydration into a deadly epidemic – More very hot days….drinking soft drinks rather than contaminated water to rehydrate…maybe some other factors  - kidney disease rise dramatical in laborers in Latin America.

5 Ways to Prevent Food Waste in Your Kitchen – Probably nothing new here but always worth a quick check…ratcheting up what you do to avoid wasting food.

Maps Show a Dramatic Rise in Health Insurance Coverage Under ACA – I was interested in seeing the trend…and wondered if the decline in uninsured people will correlate to better health outcomes.

Many US Freshwater Lakes could surpass ‘safe’ chloride levels within 50 years – Not good. Road salt is evidently a significant contributor.

Is the world running out of fresh water? – The world’s major aquifers are being drained. Mexico City – built on ancient lake beds, is now sinking in some areas at a rate of 9 inches per year! Global water demand is projected to increase by 55% between 2000 and 2050. So the answer to the question is ‘yes’ --- unless we change the way we currently use water.

Vitamin B diminishes effects of air pollution induced cardio-vascular disease – Interesting study…not actionable yet…but I hope they continue the research.

7 cool facts about Water Striders – I frequently see water striders when I’m hiking with elementary students on field trips. This article has some great pictures…and more that I had known about them previously.

Preserving Spring

When I used twigs to show pre-schoolers about how the tree buds and seeds looked during the spring…it occurred to me that it would be good to have those items to show for more than just the early spring. I decided to enclose some of them in clear contact paper. Maybe the plastic would seal off enough air to keep the plant material from deteriorating…and it would not require the heat of a laminator. The red maple samaras were my first experiment. The seed part of the wings bulge a bit, causing a little bubble. As I looked more closely after I’d finished encasing them front and back with the contact paper, I realize there are still remnants of the flower (red) where the seed is connected to the small stem.

My next attempt was with sycamore leaves that had unfurled from the branch I put in water after I cut it when it has enlarged buds.  I got several sizes of leaves from the buds that split open and have leaves unfurling now (see my previous post about from a few days ago).  The smallest ones are the size of a finger nail. The clear contact paper on both sides makes it possible to view both sides of the little leaves and to notice that one is still curled – not quite unfurled from how it was packaged in the bud.

I had some sycamore leaves from last summer that I had pressed in a book. I used the contact paper with them too. They are very dry and fragile at this point but the contact paper may stabilize them. The leaves are the size of my hand or larger. One of the them had lots of holes in it….so would be good to reinforce that trees are food and home for other creatures.

Next time I am a volunteer naturalist talking about trees….I’ll see if they survive!

Prius Prime – Month 3

I am still on the first tank of gas in my Prius Prime – over 700 miles and it is finally not quite ‘full’ (although it is not even to the first mark away from it yet)! The around-town trips are almost all within the EV range of the car. I’ve discovered that using the adaptive cruise control as much as possible when I am on any street with a speed limit over 40 mph is the way to maximize the range of the battery power. I will have to take a more substantial road trip to use up the tank of gas.

I have started my volunteer naturalist work with the Howard County Conservancy so the passenger seat of the car is the repository for things I might need – a hat for if its sunny, various jackets in case it is cool, and boots for if it is raining hard.

I’ve put sunscreen and insect repellent in the door pocket.

The next 6 weeks are going to be busy ones…the only requirement to keep the gas tank at about the same level is to remember to plug in the car when I get home!

The biggest energy challenged facing humanity – One point that this article makes: in the future, some appliances (like dish washers) will run when electricity is most available/least expensive. I already have that situation with my Prius Prime – I charges in the middle of the night when electricity from our utility is at the lowest rate. If I had solar panels on my house….I would charge it on sunny days!

Prius Prime and Samsung Galaxy S7

I thought for sure I’d made a road trip sometime during my second month owning the Prius Prime but we took the new Honda CR-V for the road trip to Pittsburgh (more on that in the posts over the next few days). I’ve included a picture of the car with a backdrop of snow piles at the South Mountain rest top on Interstate 70.

We did tease out about how much the electricity cost to charge the Prius Prime for my “around town” driving: the car got about 300 miles on about $5 of electricity!

I’ve had my Samsung Galaxy S7 for about a month….have most of the apps I’ll use frequently loaded. I leave it on my desk when I am at the computer – plugged in so when I leave it is always fully charged.

I added the app for my grocery store (Wegmans) so I can see the coupons I clipped electronically, experimented a little with the iNaturalist app for BioBlitz and used several apps while I was traveling recently: FlightView (to get the current info for my air travel), the Accuweather forecast for where I am and where I am going, and texts to people I need to connect arrival and meetings. I also have started using the phone for (Kindle book) reading on the plane.  I bought a lanyard phone holder so the phone is attached to me (without me dedicating a hand to it) in the grocery store and on the plane. I’m still experimenting with the length of the lanyard but the holder part works very well and will attach to just about any lanyard.

I’m very pleased with my 2017 tech purchases and am still learning how to best apply them --- using the technology effectively for the way I want to live.

Diet and global climate change – Making dietary changes could dramatically reduce the risk of coronary heart disease, colorectal cancer and Type 2 diabetes (and associated health care costs) and greenhouse gases!

Two Big Trees

Last week on a misty morning, I heard the noise of chain saws and heavy equipment coming from the back of a neighbor’s house. By the time I got out on my deck to look, one of the uppermost branches had be cut off and was being lowered to the ground. It was a very tall tulip poplar that was at the edge of the forest and evidently had moved around a lot during the last wind storm – enough to cause the homeowner to decide it need to come down before it fell on the house.

I went upstairs to my office to get a better vantage point. Yes – there is a reflection that gets in the right side of the images…but I decided to document the process from my office. The crew had a truck with a tall boom. A person was on the controls for the truck and a person was up in the tree….and another man went up to attach ropes to the next branch to be cut so that it could be lowered slowly to the ground.

Another big branch – being lowered to the ground.

And the person going up to attach the rope to the next branch (he looked like he enjoyed the job!).

The branch comes down. Notice the rope that is holding it up…and will allow for it to be gently lowered to the pile.

And now the big trunk begins to come down. Note that the tree is not hollow or rotten. Tulip poplars are notorious for toppling in strong winds…and evidently they don’t have to be sickly for it to happen.

And then I realized that they were cutting down two trees instead of one. Here is the last cut to take the second tree down and

The big trunk being gently lifted to added to the pile.

Then it was all about clean up. It took about 7 hours of work for the crew to get the 2 trees down (and one branch that was rotting from another tree) and everything cleaned up.

I felt depressed that two trees at the edge of our forest were gone…but no one wants a tree to fall on their house.

Automatically darkening windows in a wide range of colors – Maybe insulating drapes will not be needed in the future…although I like the idea of windows that generate power rather than just changing color.

From Vector to Zoonotic: A Glossary for Infectious Diseases – Some of these words are used in news stories without definition….how strong is your knowledge of what they really mean?

How Blizzards and Extreme Cold Impact Birds – We haven’t had any extreme cold in our area this winter….but it may be happening somewhere. This article talks about the studies about how birds cope with the cold; some succumb to the cold itself and some starve because their food source becomes unavailable.

Why Killer Viruses are on the Rise – An outcome of our increasing impact on environments that previously were wildlife habitats.

Winning images of the Underwater Photography of the Year Contest – Eye candy…but educational too.

NASA’s Osiris REx takes its first image of Jupiter – We saw Osiris REx launched last September so I always take a look at any new news about it.

Torpid Turtles, Tortoises, and Terrapins – Examples from turtles in the US…several are common enough in Maryland that I’ve seen them.

The oldest grave of the Netherlands, “Trijntje” – A facial reconstruction of a woman buried 7500 years ago.

The Feather Atlas – A feather reference. I hope I remember this exists the next time I find an interesting feather!

Ten Little Celebrations – February 2017

Usually February has been a low-key month with weather dampening activity. This year – the weather has been mild – and my celebrations have been more active than usual for February.

I celebrated outings to 1) Conowingo (for Bald Eagles), 2) Brookside (for witch hazel and snow drops), 3) Mt. Pleasant (skunk cabbage), and

4) State College (to see my daughter and son-in-law.

There were also learning experiences to celebrate: 5) the TED dialog with Yuval Harari (I enjoyed his “A Brief History of Humankind” via Coursera back August 2013) and 6) The Changing Global Order course on Coursera (from Universiteit Leiden).

There were new (big) purchases to celebrate: 7) a Samsung Galaxy S7 and

8) a new Honda CR-V for my husband (I am celebrated more room for me in the front passenger seat than in his previous car…and I am still celebrating my Prius Prime every time I drive it).

Two things for myself that I celebrated this month: 9) a short haircut that maximizes the little bit of natural curl my hair has and 10) lots of lots of Zentangle tiles (new pens and more time than usual to create tiles).

I had a lot of celebrate in February 2017!

Prius Prime – Month 1

My Prius Prime (plug-in hybrid) ownership is one month and counting. I am still on the first tank of gas (still registering as ‘full’) with about 300 miles on the car. I’ve discovered that unless I take a road trip, it will take months to use a take of gas!

I have learned more about the car since my last post about it:

• Now that I have a smart phone – I’m getting used to the wireless charging surface in the car.
• The charging happens between 11 PM and 7 AM when the electricity costs from my utility are the lowest (the car has a feature that allows setting of charging times so I set it to start at 11:10 PM and it finishes well before 7).
• The audio system can play music from a USB drive – so I have one that I plan to just load up with music and leave in the car. Later, I may use music from phone but the USB option is working so well that I am not motivated to change right now.
• There is a handy slot for sunglasses in the ceiling and I’ve started using it.

The permanent license plates came during the month --- so everything is complete. I really do want to take it on a short road trip!
