Gleanings

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

Gleanings for this week

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.

Volunteers Spot New Sites in Aerial Images of England - Archaeology Magazine – Volunteers and lidar scans…a productive combination!

Seven highlights from 70 years of the National Science Foundation - The Bridge: Connecting Science and Policy - AGU Blogosphere – Deepwater Horizon oil spill, public radio and television, ozone hole, strong curricula for introductory science, deep-sea exploration, student opportunities, and COVID-10 response. It seems like the list it too skewed to recent years.

We don’t need nearly as much protein as we consume - BBC Future – Another recommendation of getting nutrients from food rather that highly processed food or supplements….and moderation too. Skewing the diet toward protein at the expense of other nutrients is not healthy!

The Coolest Kingfishers from Six Continents – I’ve seen the first three! All three in south Texas and the Belted Kingfish elsewhere too.  Kingfishers are an easily recognized shape….heavy bill, bigger head relative to body…etc.

How Americans are coping with COVID-19 stress -- ScienceDaily – This report was prior to the additional stressor of George Floyd’s death….the racism of police evident in the videos of the event and the response to protests that seems too militarized. It seems like 2020 will be a pivot point in our nation’s history and how we all respond to the stressors of the year is important in the outcome. I hope that we can show the best of ourselves…our utmost caring for all people and our planet that is our home.

Ice Arch Persists Despite Warm Arctic – It won’t last long…the ice arch which prevents sea ice from drifting south generally breaks up in June or July. Last year it broke up in mid-April.

'New' Footage of Benjamin, the Last Tasmanian Tiger Ever Seen Alive | Smart News | Smithsonian Magazine – A 21-second video from 1935.

Top 25 birds of the week: Seabirds - Wild Bird Revolution – I’ve seen most the North American birds in these photographs….except for the puffins.

Babies know when you imitate them -- and like it -- ScienceDaily – Most parents probably realize this to some extent…but the research teases out more specifics about how babies respond to knowing they are being imitated.

The remarkable power of the prickly pear - BBC Future – Grown as a crop for food in arid areas and then using the waste left after the food is extracted to generate biofuel. Wish we had more processes like this.

Unique activities for yesterday:

Aftermath of thunderstorm. I did another early morning in the outdoors – noting the aftermath of the thunderstorm the night before. Both birdbaths had been filled by the rain. The one in front is surrounded by day lily leaves…I’m not sure how often it is used by birds, but I like the way it looks from our front door.

The sycamore tree trunk still looked very wet. I had forgotten the Virginia creeper climbing up. There were a few sycamore leaves that were blown into the yard…but the wind must not have been too bad.

The wetness of the leaves kept some of the maple leaves flipped over. It’s always surprising that the underside is so light in color.

Finally, I noticed a dead bee just before I settled into my chair. It must have gotten into the screened part of the deck and not been able to escape.

The rest of my outdoor time I spent making a couple of Zentangle tiles….and listening to the birds.

Mint as a fresh veggie. Mint grows so easily and comes back year after year. My front flower bed has a lot of it…enough to use it for more than a garnish. I cut a handful of stems and strip the leaves – it is the leafy green in a smoothie with chocolate protein powder. Yummy!

A Zentangle Prompt

Make a two tangle tile today with ROSCOE and SAND SWIRL.

Here is a tile I made yesterday based on the prompt: Three patterns to combine in a tile today: FAUX WEAVE, FEATHER FALL, and MEER.

Gleanings of the Week Ending February 29, 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. 

Hummingbirds' rainbow colors come from pancake-shaped structures in their feathers -- ScienceDaily – Hopefully they’ll produce some illustrations for these findings; this article and the materials it came from are just text.

New Discoveries in Human Anatomy | The Scientist Magazine® - It’s surprising the things we are just now discovering about our anatomy. Back in the 1970s when I was getting an undergraduate degree in biology, I remember being disappointed that there was so much obviously missing….and then realizing there were also unknown unknowns (thing we didn’t even know we didn’t know)! In the intervening years more has been researched, but we still have lots to explore.

Processed foods highly correlated with obesity epidemic in the US -- ScienceDaily  - I have kept a food log for the past few years and now am paying more attention to reducing the processed and ultra-processed foods that I buy and eat. Most of us probably intuitively know that the store-bought cookies, chips, snacks, etc. are not what we should be eating. And they aren’t even more convenient than foods like carrots or apple or grapes. I’m skewing my purchases at the grocery store to the produce aisle!

Top 25 Wild Bird Photographs of the Week: Doves and Pigeons - Wild Bird Revolution and Nectarivorous Birds - Wild Bird Revolution – Two groups of bird photos this week…catching up on the backlog.

Image of the Day: Flock in the Night | The Scientist Magazine® - A huge flock of birds picked up by radar going from Cuba…over the Florida straits…on to mainland Florida.

The chemistry of snow and ice – We haven’t seen much snow and ice in Maryland this winter...but it’s a good time to bring up this topic.

Children to bear the burden of negative health effects from climate change -- ScienceDaily – We need to use these types of articles to motivate us to action rather than indifference/depression.

FS1205: Tree-Dwelling Lichens (Rutgers NJAES) – A short description of lichen. Did you know there are at least 13,000 species of lichen?

The 2020 Community Power Scorecard | CleanTechnica – A map of the US and the scorecard with some details – state by state. There is progress being made in the transition to renewable energy!

New, more appealing varieties of kale in the works - UPI.com – I like kale. I buy it in a bunch to avoid plastic bags or containers…use it in smoothies or stir fries or soups (the whole leaf and stem) and as chips. I rarely use it in salads (particularly during the winter when I tend to want something hot rather cold for meals). Chopping it up in the food processor (like in smoothies or before adding it to soups) makes the toughness of the stem and leaves a non-issue. Still – I would try the new varieties. I wonder how long it will be before some of them show up in my CSA share.

Sunflower pollen has medicinal, protective effects on bees -- ScienceDaily – Sunflowers – a nice addition to pollinator gardens.

Research forecasts US among top nations to suffer economic damage from climate change -- ScienceDaily – The study found that the top 3 countries with the most to lose from climate change are the US, India and Saudi Arabia. China is in the top 5.

Do MoCA and Other Cognitive Screening Tests Work? | Berkeley Wellness – A short article that introduces some terminology….but not very satisfying. This is not an area where medical intervention has made great strides – unfortunately for an aging population.

Top 25 Wild Bird Photographs of the Week: Birds in Flight – National Geographic Blog – Birds in motion…a photographic challenge.

BBC - Future - Do we really live longer than our ancestors? – Life expectancy has increased because more of our species are making it to old age; life span has not changed much at all through history. The emperor Augustus lived to be 75 in the 1st century (his wife live to 86 or 87 years) and Japan’s Empress Suiko lived to be 74 in the 6th century. Cicero’s wife lived to be 103.

Prehistoric art hints at lost Indian civilisation - BBC News and An Unknown Ancient Civilization in India Carved This Rock Art | Smart News | Smithsonian – The same story from two sources. The first one is more detailed.

The Seven Cs of Education | What's Next: Top Trends – 2 items: the 7 Cs and the nature of creative thinking.

Secondary forests have short lifespans: Most don't last long enough to provide habitat for many forest species -- ScienceDaily – Making large scale commitment on reforestation requires long-term vision….and that appears to be lacking. The study was done in Costa Rica.

Infographic: Light Pollution Threatens Species | The Scientist Magazine® - It not just birds and bats….light pollution impacts a lot of organisms…including us (not the last item on the list ‘desynchronization’).

Belmont Hikes with Summer Campers V

The theme for last week’s summer campers at Howard County Conservancy’s Belmont location was STEM (Science – Technology – Engineering – Math). I decided to a pick some STEM related activities that were more like field work than actual hikes.

As usual there were two groups of about 15 each. The first group was the younger one; some of that group were just getting ready for kindergarten. I started out by handing a ruler to each camper.

We started by using the rulers to measure samples I’d brought in a bin (a stick and tulip poplar seedling were popular) and parts of the nearby barn. We did quick tutorials for campers that had not used a ruler before. One student measured one of the tiles – discovering that it was the same across and up/down (i.e. a square). Six campers collaborated to measure the lentil over a low window of the barn (5 feet 4 inches)! Most of the time we tried to measure in centimeters although we used both sides of the ruler.

I started a log of everything we measured on a pad of paper and clipboard.

We measured most of what we encountered on our hike including flowers, several feathers, grass, pine needles and cones, a fake rock (used to cover equipment), holly leaves and berries, a stump and and some very colorful mushrooms.

The second group campers were a little older – up to 12 years old. First, we talked about examples of science new sources (like Science Daily). I used an article about the discovery of moths roosting in hollow trees in Florida as an example. Then I showed them the information about the moth in the Maryland Biodiversity Project site…the way I knew the moth lived in Maryland as well as Florida. And we all knew there was a hollow tree nearby.

I had two small flashlights and we started out.

We didn’t find any moths but there were a lot of spider webs in the hollow tree. There was something there that kept the spiders well fed! We found a dead cicada nearby in the grass and examined it closely before we started out next activity.

The second activity with the group was to determine the height of a tree using a piece of paper and a tape measure. The technique worked but after using it for 2 trees we decided a 25 feet long tape measure for measuring trees over 125 feet tall was too painful (we measured a tulip poplar and white pine)…and it was too hot for more field work. We headed back to the air conditioning and lunch.

It was the last day of summer camp at Belmont. These STEM themed hikes were a good finale for us all. Everyone is getting ready for school to start…and the training sessions for field trip volunteers start 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.

Chemists characterize the fatal fungus among us -- ScienceDaily – Aspergillus fumigatus is deadly to people with compromised immune systems. It affects more than 200,000 people annually including 25% of all leukemia patients – killing half of them. Understanding more about the organism may enable better screening and treatment.

 Learning from ‘little monsters’ -- ScienceDaily – Research on macroinvertabrates. Since I volunteer for field trips with schools to streams and rivers to sample these critters – I read anything that comes up in ScienceDaily about them.

How Rising Seas Could Threaten the Internet - Yale E360 – Within the next 15 years, 4,67 miles of fiber conduit and 1,101 notes in the US are expected to be underwater. New York, Miami and Seattle will be the most effected.

Pic for Today – Point and Shoot Photographer -  Nature photography with a point and shoot camera. I subscribed so I get the picture and short description with my news feeds every day.

Allergy clinic finds large percentage of anaphylaxis cases from tick bite meat allergy: Increased awareness, more available testing led to 33 percent of cases identified as alpha gal allergy -- ScienceDaily – Wow! This is not good. Lyme Disease is serious but not anaphylaxis serious. We’re going to have get even better at avoiding tick bites.

AGU and AAS: Working Together to Expand the Understanding of Exoplanets - From the Prow - AGU Blogosphere – There seem to be more areas where we are acknowledging that interdisciplinary approaches are needed. The old lines of specialty can be limiting.

Hollow trees host massive moth slumber parties -- ScienceDaily –black idia moths in Florida are found in roosting in hollow trees during the day (they are active at night like most moths). The post didn’t identify the species but there are black idia moths in Maryland. I am going to start looking more carefully in hollow trees when I’m hiking although it’s already close to the end of the season.

Great Fall-Blooming Plants for Pollinators - The National Wildlife Federation Blog – The fall-blooming plants are not just for bees…they help the butterflies too!

Free Technology for Teachers: Take a Look at Microsoft’s Free Hands-on STEM Lesson Plans and Projects – I am going to take a look at these…see if there are any that could be easily incorporated into field trip conversations this fall.

Top 25 Arid Birds – National Geographic Blog and Top 25 Woodland Birds – National Geographic Blog and The Best of the Top 25: Part 1 – National Geographic Blog and The Best of the Top 25: Part 2 – National Geographic Blog – Birds and more birds! I’m catching up on a lot of ‘top 25’ posts that have been accumulating.

Millennials Begin To Change The Face Of Camping In National Parks And Beyond  - Positive trends – more people camping…and more diversity. Great vacations…outdoors.

Historic Low Sea Ice in the Bering Sea: Image of the Day – Big changes to the amount of ice.

Algae Blooms in Lakes & Oceans Creating Pollution That Harms People, Pets, & The Planet | CleanTechnica – Who want to do anything in green water. Ugh! Another reason to slow the flow and reduce the extra nutrients that we send into our rivers, streams and lakes (that cause algae blooms).

World’s Largest Victorian Glasshouse Opens Doors After Five-Year Restoration Project | Smart News | Smithsonian – It’s easier to the structure of the building at this point…before the many new plants get very large and block the view. The building was originally opened in 1863…and this was it first restoration.

Alligators on the beach? Killer whales in rivers? Get used to it: Large predators once hunted to near-extinction are showing up in unexpected places -- ScienceDaily – Rebounding populations! They are returning to hunting grounds where they were common before hunting caused their near extinction.

Five Tips to Help Frogs and Toads in Your Yard: The National Wildlife Federation – Good recommendations for frogs…and wild life in general. I may repurpose my daughters old ‘turtle sandbox’ into a vernal pool (but will have to monitor it for mosquito larvae)

Why Teenagers Should Understand Their Own Brains (And Why Their Teachers Should Too!): NPR Ed: NPR – After being around middle school students this week…this article caught my interest. I’m glad we are learning more about the teenage brain and can come up with solutions to the problems caused to their sleep pattern by early school start times.

How Seeds from War-Torn Syria Could Help Save American Wheat - Yale E360 – From a seed bank near Aleppo…saving the seeds from the bank by taking them into Aleppo to Lebanon and now Kansas State and North Dakota State Universities developing wheat that is resistant to Hessian fly which has been an increasing problem with climate change (higher temperatures enough that the flies were not killed by the cold of winter, less water) significant enough that US grain yields were falling. Hurray for a diverse seed stock (and the US should take note to develop diversity rather than destroying via monoculture agriculture).

For how long will the USA remain the Nobel Prize leader? Empirical study on historical development allows a prognosis -- ScienceDaily – The graph is not positive for the US. It looks like the UK is recovering from a trough that developed in the 1990s while the US peaked in the 1980s and has been going down since then (the metric being Nobel prizes per year per 100 million inhabitants).

Why I Speak Up for Science – National Geographic – A short piece about the need for science in everyday life….why science is important for everyone.

From property damage to lost production: How natural disasters impact economics -- ScienceDaily – The economic impact is more than just a single point of property damage and lost production…there is a ripple effect that can increase the overall impact significantly over what insurance covers and it beomes a very complex problem to estimate.

European Union Bans All Outdoor Uses of Neonicotinoids - Yale E360 – Shouldn’t we in the US be at least this concerned about the health of bees and other pollinators? Why have we not done more to curtail the use of neonicotinoids?

Top 25 Urban Birds – National Geographic – Some birds are thriving in the cities of the world.

Common Eye Disorders Explained: Cataracts, Glaucoma, AMD | Berkeley Wellness – Prevention, signs and symptoms, treatment…well organized and easy to understand.

These daggers made from human bone were a deadly asset on the battlefield | Science | AAAS – They are from New Guinea….and decorated. Most of the time they were made from cassowary leg bones….but sometimes human thigh bones were used.

US gains in air quality are slowing down: New study indicates challenges of meeting ozone goals -- ScienceDaily – I live in an area that has an increasing number of ‘code red’ days (high ozone). This study indicates that emissions from cars and power plants are understood well enough…but not other sources and that is probably why the trend toward better air quality is slowing down.

BBC - Future - How prison changes people – Evidently the personality change that dominates is an inability to trust others….but there are other common changes as well. Prisons almost seem design to change personalities for the worse.

City upbringing, without pets, boosts vulnerability to mental illness -- ScienceDaily – We need to figure out how to make cities a healthy place for everyone --- including children.

BBC - Future - Why pristine lakes are filled with toxins – A study done on Lake Geneva revealed cadmium, mercury, lead…sometimes in high concentration…from decades of plastic build up in the lake. Other studies of the microplastics in the water (and in water that has been processed for drinking) and then beer and honey from the area. Lots more research is needed on the impact to wildlife in and around the lake.
