Filling a Day of Social Distance – 3/25/2020

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Relaxing with an at-home facial. I found a pomegranate mask packet that I’d had for months…enjoyed it while I listened to a video that was about 15 minutes long…the time in the directions for the mask.

Catching up on the Life in the Universe Pandemic Series from Charles Cockell:

• Why is everyone so excited about Europa?

• Can prisons help explore space?

• Are viruses alive?

Scheduling a grocery delivery. I placed an order for delivery with my grocery store on 3/25 (morning) and it going to be delivered on 3/27 (afternoon) to my front porch. This is a first for me and I have all the usual concerns – will the bananas be bruised and produce wilted? Will they have everything on my list? Will they make good substitutions if what I requested is not in stock? I guess I’ll find out on Friday afternoon.

Noticing that the tulip poplar is leaving out. The little leaves have the tulip poplar shape almost immediately. The flower buds are still just enlarging.  

Receiving most of our orders. We wash ours hands with soap and water after we bring boxes or envelopes into the house then let them sit around unopened for a few days to give any coronavirus on them plenty of time to die. The most critical outstanding one came on 3/25 – the last of our over-the-counter medications supply that would help us with symptoms should we get sick. The only package we are still waiting for is the bugs we ordered back on 3/19; it’s good to have a project ‘on the way.’

Catching up on shredding. I collect items to shred around the shredder….doing the job when I need ‘browns’ for my compost pile. Toilet paper rolls are my favorite because they are an easy size for my shredder, and they are unbleached cardboard; they deteriorate very rapidly in the compost pile with my kitchen scraps and other ‘greens.’ I plan to empty out finished compost on the next nice day and restart the pile….so the shreds will be outdoors and fodder for decomposers within the next few days.

Trying some macro shots of spicebush leaves. The leaf buds on the small spicebush plant that I brought inside have popped. The leaves have not quite unfurled yet. The flowers are done for the year….but maybe some of them will make seeds if they were fertilized before the branch was brought inside.

Gleanings of the Week Ending March 21, 2020

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.  

Can Destroying Senescent Cells Treat Age-Related Disease? | The Scientist Magazine® - Lots of trials going on…this may be a way to extended years of healthy life (not elongate life).

This 'Blood-Red' Snow Is Taking Over Parts of Antarctica | Smart News | Smithsonian Magazine – I remember seeing snow that was the color of watermelon in Colorado…it’s algae Chlamydomonas nivalis, which is the most common type of snow algae around the world. It hasn’t been as common in Antarctica until this year.

Spotted Zebras, Yellow Cardinals, and Three-Antlered Deer: What Causes these Animal Oddities? • The National Wildlife Federation Blog – Some uncommon forms of animals we all recognize.

What Makes a Venus Flytrap Snap | The Scientist Magazine® - It’s complicated…and nuanced so that the plant only invests in digestion efforts when there is food!

Just a Tiny Fraction of America’s Plastic Can Actually Be Recycled, Report Finds - Yale E360 – We can’t send it to China any more…so it’s all on us to clean up our own mess. Unless and until we can get recycling working well…it’s important for all of us to reduce our use of plastics as much as possible. It’s hard to do.

States with highest rates of melanoma due to ultraviolet radiation identified: Several landlocked states among those with highest rates -- ScienceDaily – It’s not all about being out in the sun either. The prevalence was higher in younger females due to tanning bed usage by teen girls in the late 1990s contributing.

Interactive Infographic: How Salt Transforms Coastal Forests | The Scientist Magazine® - We noticed this process as we’ve visited Blackwater National Wildlife Refuge over the years. There are some areas that used to be marsh with some trees that are now open water.

Top 25 birds of the week: March 2020 - Wild Bird Revolution – No birding festivals in our future near term….but still enjoying pictures taken by others.

Why your internet habits are not as clean as you think - BBC Future – A good compilation of studies about energy consumption for various aspects of our online activities….maybe we can skew toward the lower energy use ones more frequently. Some of the energy, we pay for in terms of our electricity use….others are embedded in products or services we use where the energy usage is not something we see directly.

Coronavirus: How hand sanitizers protect against infections – Compound Interest – Some timely chemistry.

Filling a Day of Social Distance – 3/19/2020

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday…a cloudy day that started out very wet:

• Trying another grocery store – first thing in the morning again. We found meat! It wasn’t our usual organic…but we bought it anyway. We also found some spray Lysol but not disinfecting counter cleaner…we are using our backup plan which will involve gloves, open windows and fans on (fortunately we are going to have some warm days). We got the medicines we would need if we got sick and my husband’s favorite protein shakes. Still no toilet paper or cat food. We ordered the cat food online when we got home.

Reducing toilet paper consumption dramatically. We have water in spray bottles beside our toilets now. We haven’t eliminated toilet paper entirely…but we are building up our skills with the water. It should enable us to manage with the toilet paper we have in the house for a few weeks even though we have not been able to find any in stores recently. Maybe this strategy will last beyond this crisis….it would make sewage treatment easier and reduce the number of trees felled to make toilet paper.

• Noticing that I am sleeping as well as ever (according to my Fitbit…and not feeling tired). It’s an indicator that I am still handling the stress of the pandemic and changing habits very well. Another indicator from my Fitbit: my resting heart rate has stayed below 65 (normal for me) the whole time.

• Cooking sweet potato hash browns. We cook and eat at home most of the time. But I have more time now, so I am beginning to experiment. I got the idea for hash browns from my husband requesting the frozen variety of hash browns when I went to the grocery store…but I changed the potato from russet/white to sweet for my dinner! I scrubbed the sweet potato and cut off the ends…chunked it so it would fit in the food processor with the shredder attachment…cooked them in a little olive oil seasoned with onion flakes and no-salt seasoning. It made a good meal with scrambled eggs…pretty orange and yellow colors on the plate.

• Filling the bird feeder. We let the bird feeder hang empty for the past week to discourage a hawk that has become too interested in our backyard. Now we get to observe how long it takes for the little birds to find the seed again. Are the juncos still around?

• Unpacking the bin prepped for a Zentangle® class. My plan for 3/19 from back in January was to lead a Zentangle session for my fellow volunteers after a training session for spring field trips. That has all be cancelled – of course. I am unpacking the bin I had already prepped: color zipper pouches with square paper coaster tiles, Pigma Pen 05, and pencils. I am going to use the bin to put all the photos I found in decades-old boxes in our basement…put the smaller bin of pouches on a shelf in my office. I couldn’t resist opening one pouch and tangling!

• Browsing through emails and feeds with suggestions from others re navigating through the upheaval coronavirus is causing. An email from Coursera (lots for free online courses) had several interesting links that I want to pass along:

  • If you or someone you know is learning online for the first time: You can share these 8 tips from our Teaching & Learning team.

  • If you’re looking for ways to keep learning with your kids: Talk with parents around the world and share your favorite resources.

  • If you’re looking for advice about moving in-person learning online: You can reference these best practices from our Teaching & Learning team.

  • If, like Coursera, you and your team are shifting to remote work: You can join others in our community to discuss strategies and share advice.

Filling a Day of Social Distance – 3/17/2020

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

• Picking earrings to wear that I haven’t worn in a long time. Yesterday I wore some from Orlando FL and today they are from Watkins Glen NY. Earrings are my favorite item to purchase when I travel…small keepsakes that I can wear! Both are over 10 years old, but I still remember where I got them.

• Maintaining the compost pile and walking around the yard. I’m trying to get out of the house at least once a day….enjoy that it is springtime here!

• Watching the second installment of the Cincinnati Zoo’s Home Safari (about Rico the Porcupine). They have established a website where all the videos will be available after they air live. I am watching the recorded version, so I don’t have to pay attention to the time to be online at 3 PM EDT!

• Calling family far away, I had planned to be in Texas this past week…but I was already ‘staying at home as much as possible’ a few days before I was going to get on the airplane. Talking on the telephone is the next best thing for keeping in touch until it is not as risky to be out and about in larger groups of people.

• Making a Zentangle® butterfly. I was straightening up my office and found a few extra butterfly tiles left from last summer’s experience with summer campers. I couldn’t resist using the tile…thinking that this would be a good activity for anyone needing a quiet calm time. If you want to learn a new pattern, checkout out https://tanglepatterns.com/ . Later in the afternoon. it was warm enough that I saw a real butterfly - a cabbage white.

• Watching the 4th video in the ‘Life in the Universe Pandemic Series’ from Charles Cockell - Why didn’t dinosaurs build a space program? His pet gecko, Europa, is part of the lecture too!

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.  

Shrikes: Meet the Bird That Impales Prey on Spikes – The bird creates its “pantry” on barbed wire…other spikey objects. Gruesome…but it’s an adaptation that works for the bird.

The color of your clothing can impact wildlife - ScienceDaily – For water anoles – orange is better than green if you want to see the lizards!

We're Destroying Virgin Forests for Toilet Paper -- What Are the Alternatives? | CleanTechnica – Not good! We in the US are the biggest users…change is hard.

Why Clouds Are the Key to New Troubling Projections on Warming - Yale E360 – Fewer clouds as the planet warms? If so, we’ll heat up more because more solar energy will strike the planet. That’s what the most recent models are predicting and real-world data from satellites suggests that the modelers’ predictions may already be coming true. We’ll have less snow and ice around too to reflect solar energy back into space. It seems like we should make all sky facing manmade surfaces (like roofs) white or lighter colored (unless they are generating energy)…and look for other opportunities to reflect like clouds.

New Research Rewrites the Demise of Easter Island | Smart News | Smithsonian Magazine – There is mounting evidence that Easter Island people created the statues until at least 1750 – after contact with Europeans. And their population has been relatively stable since the 1400s. By the time the British explorer James Cook arrived in 1774 the statues were in ruins. By 1877, just over 100 people remained on Easter Island.

How do woodpeckers avoid brain injury? – Woodpeckers avoid concussions with some adaptions: 1) specialized skull bones, neck muscles, beaks and tongue bones 2) less internal fluid surrounding their brain to limit the motion of the brain during pecking. Interesting…and maybe can help devise ways to protect and heal human brain injuries.

Anti-solar cells: A photovoltaic cell that works at night -- ScienceDaily – Some research…potentially a way to balance solar power over the day-night cycle.

How did the last Neanderthals live? - BBC Future – From caves in Gibraltar….the insight that they were much more like us than we once believed: they exploited seafood and marine mammals (they could swim…hunted dolphins), wooly mammoths, woolly rhinos, ibex, birds (maybe used their feathers…particularly the black ones); they decorated walls and shells; their hyoid bone was like ours (which means they might have had speech like ours); they made tools of bone that were copied by modern humans.

Florida scientists study health effects from exposure to toxic algae - UPI.com – Blue-green algae toxins make people sick (liver damage/disease, skin rashes, headaches, trouble breathing) but does it cause disease when it is absorbed via breathing (i.e. airborne particles) during algae blooms? Fish kills are bad too. It’s good to research the topic but shouldn’t we do everything we can to prevent the blooms in the first place?

Researchers Find Cell-Free Mitochondria Floating in Human Blood | The Scientist Magazine® - Surprise! Now to figure out their function….

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.  

Chasing Little Frost Trees in a Prairie Wetland | The Prairie Ecologist – We haven’t have many days for me to look for frost trees here in Maryland this year. This is always a matter of taking advantage of a frosty sunny day when it’s fun to look for interesting frost formations on exposed surfaces – grass – windshields, etc.

Stoneflies and mayflies, canaries of our streams – It’s great to see an article about the adult forms of the insects we collect as macroinvertebrates (larval form) when we do water quality monitoring either quarterly or with high school students on a field trip to a river.

Earthquakes in and around Yellowstone: How Often Do They Occur? – There are lots of them! About 5 that are strong enough to be felt have happened each year over the past decade.

Top strategies for successful weight loss maintenance-- ScienceDaily - Choosing healthy food, tracking what you eat and using positive self-talk….seems like common sense, but it is not ‘easy’ and so we struggle on. It comes down to making changes for the long term rather than just for a little while. New habits are always tough but, once truly habitual, become just the way be live our lives.  

Eero Järnefelt, painter of Finnish nature | Europeana Blog – Images of the natural world in the late 1800s. Koli National Park in eastern Finland was visited by the painter frequently.

Sustainable Farming Comes to America's Heartland | CleanTechnica – Iowa farmers…leading with their actions…responding to climate and environmental changes to farm better.

Can we heat buildings without burning fossil fuels? - BBC Future – Capturing heat from nearby places…using it for heating. It’s geothermal in the cities!

Bloom in McMurdo Sound – Green swirls in the water off Antarctica (some of the green color might be on the ice as well.

Camera Trap Chronicles: Cool Critters of New Hampshire – Maybe sometime  we’ll put our camera, currently pointed at the birdfeeder, in another location….see what comes into our backyard. I know we have deer but there could be other things as well. Our camera already picked up what looked like a racoon on our deck.

Top 25 birds of the week: groups of birds – Beautiful birds…a good ‘last addition’ to the gleanings list this week.

Top 25 Wild Bird Photographs of the Week: February 2020 – Note the new website for these weekly posts: https://wildbirdrevolution.org/ ---The posts are still the beautiful bird pictures collected into a group for a weekly visual celebration of birds.

100% Wind, Water, & Solar Energy Can & Should Be the Goal, Costs Less | CleanTechnica – A short summary of a report with specifics for 143 countries…getting to 80% renewable energy by 2030 and completing the transition by 2050. Now to vote with that goal in mind for a livable future for ourselves, our children, our grandchildren….and onward.

LEDs, Downward Lights Changing the Night in Chicago - News | Planetizen – Chicago will complete the transition to energy efficient LED streetlights in 2021. They’ve calculated that it will save the city $100 million over 10 years. At the same time, they have made an effort to focus the new lights downward to cut light pollution. It’s too early to tell if that aspect of the project will be a success.

Vegetation Filters Harmful Particulates from Air--But How Much? | The Scientist Magazine® - It’s probably better to push for the transition to renewable energy (in school buses, for example) but where that is not happening fast enough – planting a green wall of vegetation can block pollution from school yards…which could reduce the impact of vehicle exhaust on children’s lungs.

Decline in Coal-Fired Power Reduces U.S. Carbon Emissions in 2019 - News | Planetizen – Good news…but it could decline more quickly. The 2019 results are from market forces alone. If there were political will, things would happen even faster.

Archaeologists Excavate 200 More Chinese Terracotta Warriors | Smart News | Smithsonian Magazine – The first terracotta warriors were found in China’s Shaanxi province in 1974. Now there is more excavation and more soldiers from the same tomb. All the warriors have unique expressions, hairstyle and physical features.

Organic crop practices affect long-term soil health -- ScienceDaily – This study looked closely at organisms in the soils…along with the impact of prior soil disturbance.

Recovery: A Plague of Bullfrogs – The Eastern part of the US is the native range for Bullfrogs…but they are invaders in the West. They are clearing native frogs and eating other animals too (ducklings are an example cited). So various municipalities and conservation groups are acting.

What We Can Learn From Ötzi the Iceman's Hunting Pack | Smart News | Smithsonian Magazine – Ötzi was preserved for 5,300 years in a glacier until he was discovered in 1991. A lot has been studied since that time. He’s a window into Copper Age Europe.

Photography in the National Parks – More favorite spots for photography from Rebecca Larson. This collection included three National Parks I have not visited: Glacier, Olympic and Mount Rainier. Now I want to plan a trip to see them!

All About Feathers – A tutorial on feathers…lots of great visuals (stills, videos, drawings, photos) from The Cornell Lab Bird Academy.

NOAA Research’ top 5 stories from 2019 – Catching up on some reading…the stories featured were the most popular on their site in 2019.

Capturing CO2 from trucks and reducing their emissions by 90% -- ScienceDaily – Research applicable to making transportation friendlier to the environment…retrofitting of existing trucks.

Rising Temperatures Are Stressing the U.S. Corn Belt - Yale E360 – It’s not just rising temperatures…it’s the shift in rainfall causing hydrologic stress during the summer months. Maybe the ‘corn belt’ could shift northward?

Traveler Special Report: Threatened and Endangered National Parks – In Alaska and beyond…we are losing the natural treasures we sought to protect.

The history of candy canes and why they taste so cool – I am late getting around to including this in the gleanings list. I like peppermint candy year round…even if it’s not in the candy cane shape! I have peppermint candy chips to use in snow ice cream…if it will ever snow enough this winter here in Maryland!

Largest Electric School Bus Program in United States Launching in Virginia | CleanTechnica – Dominion Energy partnering with Virginia School districts…to achieve a 50% electric school bus fleet by 2025 and 100% by 2030. Good for the environment and the lungs of Virginia’s school children. I hope other states will move in the same direction.

These infrared images show just how alive butterflies’ wings are – Surprise! Butterfly wings have living cells not just membranes and scales! The living cells can sense heat and the butterfly responds behaviorally.

 Flame retardants and pesticides overtake heavy metals as biggest contributors to IQ loss - ScienceDaily – There are a lot of things that are toxic in our environment these days…and children are the ones that are hurt the most…and the hurt lasts their lifetime. This study looked specifically at lead, mercury, poly-bromated diphenyl ethers (PDBE…flame retardants) and organophosphate pesticides.

Abstract Aerial Photos of Iceland's Rivers Look Like Watercolor Paintings – A little art photography to start out the gleanings this week.

Tomb Containing Three Generations of Warrior Women Unearthed in Russia | Smart News | Smithsonian Magazine – Evidently research is revealing that warrior women were the norm, not the exception, in Scythian culture. Scythians lived in small tribes, wore trousers (practical since they were on horseback much of the time) and fought with bows and arrows.

Protecting the Sonoran Pronghorn from Extinction – It’s complicated….lots of agencies involved….an international border that is becoming a migration barrier.

Is Notre-Dame Too Fragile to Be Saved? | Smart News | Smithsonian Magazine – Removing the scaffolding that was melted by the fire is evidently going to be a big challenge.

Whooping cough evolving into a superbug -- ScienceDaily – The research was done in Australia…but it probably applies to the US as well. Bottom line: we need to be developing an improved whooping cough vaccine.

One Reason Colorado Playgrounds Are Looking Way More ‘Natural’ | Colorado Public Radio – I like the new types of playgrounds….more than swing sets and slides…bringing in some natural elements.

White Sands National Monument Redesignated As A "National Park" – A beautiful and unique place. I’ve only been there once…but it was very memorable. The biggest surprise for me was that even on a hot day in June, the sand was not hot! Being white really does reflect the heat up and away.

2019 Year In Review: Some Great Photo Tips – So many beautiful places to photograph….take some time in a natural place (National Parks are awesome…but there are other places that are great too).

Striking Portraits of Rare and Endangered Birds by Tim Flach – I tend to like bird pictures from the wild…but these are amazing portraits. Virginia Cardinal – I was surprised to see it in this grouping…as far as I know they are not different than the Northern Cardinal. Cornell’s Allaboutbirds doesn’t have a listing for them.

Mealworms safely consume toxic additive-containing plastic -- ScienceDaily – Not an answer to the plastic problem…more like basic research that could be incorporated into a partial solution. The biggest gain comes from dramatically reducing single use plastics.

3 Free eBooks – January 2020

Starting out the new year…I selected 3 books with an art and history skew from my accumulation of reading this month.

Dillon, Edward. Glass. New York: G. P. Putnam’s Sons. London: Methuen and Co. 1907. Available from Project Gutenberg here. The book is a history of glass (up until the early 1900s) with illustrations of pieces in museum collections. I paid more attention to the illustrations than the text. I’ve always been interested in ancient glass because it points to the step beyond basketry and pottery in our manufacturing expertise. It a material we think about as being ‘breakable’ but is often very enduring.

Whitney, Frederick. Blackboard Sketching. Springfield, Massachusetts: Milton Bradley Company. 1909. Available from Internet Archive here. Written at a time when many students were learning to write and draw with blackboard slates and slate pencils…it provides an idea of how students were taught. Early classrooms used a lot less paper!

LaFontaine, Bruce. Bridges of the World Coloring Book. Dover Publication. 1994. Available from Internet Archive here. The bridges are organized chronologically. The sample image I show below is the colored version (as the end page of the book) of page 10…a bridge from China built about 1100. The book includes short descriptions the design features and technologies the bridge builders utilized. Obviously, these bridges have proven to be very durable.

Enjoy these 3 online books!

Top 25 Wild Bird Photographs of the Week: January 2020 – Starting out with wild and wonderful birds this week.

Infographic: How does nature influence human health? – Most people intuitively know that nature has a positive impact…but now there is more and more research to quantify that impact.

The Plastics Pipeline: A Surge of New Production Is on the Way - Yale E360 – Just when I really want manufacturers to find ways to package products in something other than plastic….the industry has plans to ramp up production of plastic. Consumers can still make a difference with our purchases (or lack of purchase). I’m slowly but surely reducing the items I buy that come in plastic….always looking for alternatives.

New aqueous lithium-ion battery improves safety without sacrificing performance: Non-flammable, cost-efficient, and effective battery -- ScienceDaily – Hurray for all the battery research going on right now….hopefully there will be more and better options near term. It would certainly boost the speed we can transition away from fossil fuels.

Pylos Tomb Artifacts Suggest Trade Links - Archaeology Magazine – Amber from the Baltics, imported carnelian, pendant depicting an Egyptian goddess….the Greek site might have been a stop on a trade route.

Happy New Year from Amundsen-Scott South Pole Station – Kelly Brunt posted this on January 3rd….and I just got around to looking at it. She was one of our hosts at NASA for my HoLLIE class and then the keynote for our graduation. It was good to read about her recent activities!

Super Resilient Protein Structures Preserved a Chunk of Brain for 2,600 Years – Wow – what an amazing and surprising find! And there is has been some research to figure out how it managed to be preserved.

Towards Ecophilia: Being hopeful in spite of it all -I enjoyed the pictures and activity descriptions about children in nature.

How US sewage plants can remove medications from waste-water – Using granular activated carbon and ozonation….more than 95% of certain antidepressants and antibiotics can be removed. This is important to help reduce the development of antibiotic resistant bacteria and maybe other environmental harms as well. But it can be expensive.

The oldest person in the world turns 117 – I liked the last paragraph of the story the best: Last year, when Tanaka received her record for the world’s oldest person, she was asked about the happiest moment in her long life. Her reply was simple: “Now.” Wouldn’t it be great if we all could feel like that no matter how old we are!

Earth at Night – This is an eBook from NASA that was last updated in December 2019….lots of pictures of the earth at night, analysis, and the technology behind the images.

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

Top 25 Wild Bird Photographs of the Week: Seabirds – Starting with the birds this week. I’m thinking about the Delmarva birding sessions later this month…they’ll be sea birds and more to see.

Clearing damaged cells out of the body helps heal diabetics' blood vessels -- ScienceDaily – Interesting….but still a lot of research needed before it could potentialy be used in treatment.

The toxic killers in our air too small to see - BBC Future – Nanoparticles – 90% of particles by busy roads are nanoparticles below 100nm. The smaller the particles, the greater potential toxicity. Anything smaller than 30 nm can make it to through the lungs and into the blood stream (larger than that doesn’t gets past the lungs). The Global Burden of Diseases study estimates that air pollution could account for 21% of all deaths due to stroke and 24% of deaths from ischaemic heart disease.

A little prairie can rescue honey bees from famine on the farm -- ScienceDaily – Food crops can provide good food for honey bees…but maybe not for the whole season.

Adult Humans Can Regenerate Cartilage: Study | The Scientist Magazine® - microRNA may have potential in human regeneration of tissue.

Agar Art Contest 2019: See this year’s winners – Art made with live bacteria.

Infrared Reveals Egyptian Mummies' Hidden Tattoos | Smart News | Smithsonian – 7 mummies – 3,000 years old. All the mummies with tattoos at the site were women.

Gabapentin: A Risky Answer to the Opioid Epidemic - The Atlantic Gabapentin has become the 10th most-commonly-prescribed medication in the US. It is viewed as a safer alternative to opioids for chronic pain….but it is problematic in combination with other sedating medication and it doesn’t work as well as hoped….particularly for back pain. It appears that looking for a quick fix for chronic pain is – again – not working as advertised.

Photography In The National Parks: My Favorite Spots For Great Photos – From Arches, Bryce Canyon, Big Bend, Acadia, and Padre Island.

Scientists Don't Know Why Freshwater Mussels Are Dying Across North America | Smart News | Smithsonian – It’s not just in one place….and may have multiple causes. But this just highlights that some mussel species that have already gone extinct…and our rivers are very different than their ‘natural’ state.

My 2019 in Review - Volunteering

I am looking back at the volunteering I did in 2019…what was like prior years…what was the same…how might things change in 2020.

Howard Country Conservancy is where I did more than half my volunteering. I enjoy the school field trips at Mt. Pleasant, Belmont and the streams around the county – “connecting people to nature”. The variety of locations and age groups keeps my interest. The field trips evolve to stay linked with curriculum in the schools but being out in the natural world is a continuing learning experience for a lifetime. In 2019 I changed the activities I did with summer campers…and volunteered more frequently during the summer than in previous years. Looking forward to 2020…it will be more of the same, but I’ll add the expertise I gained from the “Flying Wild” and “Growing up Wild” workshops to summer camp activities. The HCC staff and other volunteers are engaging and thoughtful. HCC is a great place to volunteer over the short and long term.

Three years ago, I added Brookside Gardens Wings of Fancy to my volunteer activities.  I’ve increased my hours each year. In 2020, I’ll probably do about the same as I did in 2019: 1-2 shifts per week when I am in town. The butterflies, interactions with the visitors to the exhibit, and helpful staff members keep me coming back.

Toward the end of 2019, I started volunteering at the Robinson Nature Center – specifically for the Touch Tank. I’ve enjoyed the shifts so far (I am still learning something new every time I volunteer!) and will continue volunteering in 2020. It’s an indoor venue…different from my other activities.  Right now my strategy is to volunteer more frequently at Robinson in the cold and hot months….less frequently in the spring and fall.

Overall – volunteering is my best way of connecting to my community…helping to make it a good place to be for everyone.

Reducing Single Use Plastic

As we near the end of 2019, I am taking stock of the changes I made over the past year to reduce my household consumption of single use plastic.

We’ve done the easy things at this point:

Switching to reusable shopping, grocery, and produce bags

Choosing products in paper/cardboard, glass, or metal containers rather than plastic containers

Turning some single use plastics into multiple use plastic

Carrying a spork to avoid plastic eating utensils

Bringing our own reusable water bottle and/or travel mug

Replacing broken plastic containers with glass or metal ones (an example happened recently – I bought some glass left-over containers with silicone covers that can be used in the microwave, oven, refrigerator and freezer…and go in the dishwasher for cleaning….some older plastic containers had cracked…so it was an opportunity to change)

When I look at our trash and recycle there are still some opportunities:

• We could stop drinking soft drinks (a health choice for ourselves and the planet).

• We could eat fewer foods packaged in plastic (bunched greens rather than ones in bins or bags, loose apples and potatoes rather than in a plastic bag, unpackaged fresh foods rather than frozen foods, etc.). Sometimes those are a healthier choice as well.

• We could use fewer kinds of toiletries and shift to larger containers (maybe refilling small ones if needed for travel)

But some things are very hard without companies making packaging changes:

• Liquid laundry and dishwasher detergent

• Cleaning fluids like large jugs of white vinegar, surface cleaners, toilet bowl cleaners

• Meat packaging

• Plastic envelopes

• Plastic bubble or balloon wrap

• The list goes on and on

Reducing single use plastic around our house is an continuing goal…and it’s not an easy one.

Top 25 Wild Bird Photographs of the Week: Waterbirds and Camouflage and Forests and Birds in Pairs – Starting out this week’s list with some bird pictures….catching up the backlog

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

First Global Map of Saturn's Moon Titan Reveals Secrets of Earth's 'Deranged' Twin | Smart News | Smithsonian – There are plains, sand dunes, mountains, labyrinthine valleys…and lakes of methane.

'Self-cleaning' concrete could keep buildings looking new -- ScienceDaily – Maybe a new building material…but can it be made in a ‘green’ way?

Everything You’ve Ever Wanted to Know About Turkeys – I’m just catching up on some reading…this would have been more appropriate for the Thanksgiving week gleanings…but better late that never. Turkeys are interesting birds!

Air Pollution Tied to Brain Cancer: Study | The Scientist Magazine® - Combustion-related nanoparticles can reach our brain! The concentrations of these particles in highly polluted areas are also causing other health related problems as well. For example, the air pollution in Kabul, Afghanistan may be causing more deaths than war in that area

Owling: A Field Guide to Finding Winter Owls – Seen any owls? They are often easier to hear than see.

Slideshow: Images from The World Beneath | The Scientist Magazine® - A few pictures from a new book about sea creatures and coral reefs. Lots of vibrant color and camouflage.

Eating in sync with biological clock could replace problematic diabetes treatment: An early-morning, carb-filled meal improves glycemic control among diabetics -- ScienceDaily – We are shifting our meals…largest one at midday…smallest one at night. If we eat a high carb meal it will be at breakfast. I had gingerbread cake this morning!

Flying Wild

Last Friday – I was in Annapolis for a Flying Wild class offered by the Maryland Department of Natural Resources. It was a day to learn some activities that celebrate birds designed for age groups I normally encounter as a volunteer and Maryland Master Naturalist. The forecast for the morning drive was a little threatening (freezing rain) but it didn’t materialize. It was my first time at the Tawes State Office Building where the class was held do I took a few minutes for pictures of lobby area of the building (it was rainy and cold so no outdoor pictures): Maryland symbols, a frayed Baltimore Checkerspot (which is very rare these days), a garden drawing on one of the windows looking out onto a real courtyard garden and a sculpture of a tree planting.

We did a sampling of the activities available from Flying Wild. One of my favorites was nest building. In teams of 3, we used wire to make a frame for a nest and then used materials that we had scored for strength, flexibility, and space filler. We could use as much material as we wanted except for clay; we were only allowed a golf ball amount of that. After we constructed our nest, there were tests: 3 marbles were used as ‘eggs’ (did they fit in the nest and not roll out when the nest was shaken); then some weights were put into the nest to simulate the growing chicks. It was a lot of fun and our nest ‘passed.’ We all gained a healthy respect for birds building nests with just their beaks and feet!

Of course, I come home with lots of stuff – handouts and the book…a poster and a ‘prize’ for being on the winning team for the nestling feeding relay. There were Black Eye Susan Seeds to plant next spring too!

The Two Genomes in Every Eukaryotic Cell | The Scientist Magazine® and Infographic: How the Mitochondrial and Nuclear Genomes Interact | The Scientist Magazine® - A lot has been discovered about mitochondrial DNA (and genetics) since I was in college in the 1970s!

Yellowstone's Wolves: Infusing Wildness into The Landscape – The story of wolves in Yellowstone over the past 25 years – the positive impact on the ecosystem as a whole

Sunlight-Tracking Polymer, Inspired by Sunflowers, Could Maximize Solar Power | Smart News | Smithsonian – Another way that solar panels can gain efficiency.

Springfield Plateau: Yellowjacket Nest – A yellowjacket tale from Springfield MO. I was surprised that ice was the treatment for a sting. I’ve always used baking soda with ice as the backup plan if there isn’t any baking soda available.

Why biodegradables won’t solve the plastic crisis - BBC Future – There are only pieces of a solution at this point….nothing comprehensive. It seems like the best strategy for at home is to reduce all single use plastic as much as possible. There are some easy things like reusable shopping and produce bags, but it becomes hard quickly. So many groceries and toiletries only come in plastic containers.

Remote Sensing Data Advances Soil Health Science – Cover crops and no-till practices were an advantage in record-breaking rainfalls of spring 2019.

How the House Finch Conquered Your Feeder…and A Continent – A little history of House Finches – originally from the southwest and Mexico…now in found widely across North America.

How the Aztecs could improve modern urban farming: Chinampas: An old technique might provide new solutions to sustainable urban agriculture -- ScienceDaily – The article made the multiple harvests per season seem feasible in tropical wetlands…not so much in the temperate zone where the artificial islands would go through a real winter although maybe it would just mean the use of cover crops during that time period.

Top 25 Wild Bird Photographs of the Week: December – Bird photography to enjoy!

Listening to Nature: The Emerging Field of Bioacoustics - Yale E360 – An up and coming technology for remote sensing of birds, insects, frogs and other animals.

Maryland Water Monitoring Council Annual Conference

The 25th MWMC Annual Conference was held last week. It was my third time to attend and it was, once again, a great opportunity to catch up on water-related research and Maryland specific plans, activities, and accomplishments. The two themes in the sessions I chose to attend were watershed health and remote sensing. I am hoping the agenda with links for the presentation material will come out soon since my note taking is not all that legible.

I also enjoyed the vendor tables. One of the companies that did the stream restoration at Howard Country Conservancy’s Davis Branch had a table – and a post card picturing the project (before last summer’s drought)!

One vendor had a great ‘Got Bugs? Banner and another had macroinvertebrate stickers.

There were other giveaways too – lip balm, pens, a frog shopping bag, and a folding card Field Guide to Aquatic Macroinvertebrates.

The conference was the largest every – with over 600 attendees.

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.

Red Tides Under the Microscope | The Scientist Magazine® - It’s surprising what we don’t yet know about the organism responsible for red tides – Karenia Brevis. Spanish explorers of Florida in the 15th and 16th centuries described fish kills in Gulf waters. The first official documentation was in 1882 – published in the Proceedings of the US National Museum. This article is about what we know….and where more research is needed.

The woman who reshaped maths - BBC Future – Hilda Geiringer…a refugee from the Nazis. A BBC Future column celebrating a ‘missed genius’ whose contributions are still notable in the world today.

NOAA weather balloons find no zero-ozone regions above South Pole during 2019 ozone hole season | NOAA Climate.gov – A little science…a little history…a projection. The positive message – if the trend continues, it’s estimated that the ozone layer will recover around 2070.

Abrupt shifts in Arctic climate projected: Likelihood of an abrupt increase in wildfires also noted -- ScienceDaily – With specific modeling of permafrost as it continues to degrade….it appears that the changes won’t be as gradual as  previously assumed.

Lake On Bottom Of Halema‘uma‘u Crater At Hawai'i Volcanoes National Park Now Bigger Than Football Field – The lake was noticed back in July….and is being studied with instruments on drones. More information is at the National Park Service site for the park.

Top 25 Wild Bird Photographs of the Week: Wild Birds – National Geographic Society Newsroom – I always enjoy the bird photography compiled by National Geographic every week.

Offshore Wind Has the Potential to Fulfill Global Electricity Demand 18 Times Over - Yale E360 – Hurray for this potential….the transition is the challenge.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live. On a positive note - the sediment (even after the record rains earlier this year) has not damaged the underwater grasses on the Susquehanna Flats as much as was initially feared.
