Tallgrass Prairie National Preserve: A windo into the past – A prompt for an early fall road trip? It is about 4 hours from where we live now.

Psoriasis: Study lays foundation for new treatment strategy – Hope more targeted treatment can be developed….avoiding the drugs used currently that suppress the immune system overall.

Winners of the 2022 Audubon Photography Awards Celebrate the Beauty of Our Feathered Friends – Images of birds in action.

The silent danger of gum disease – More reasons to sustain regular dental checkups….and for dentists to be vigilant.

The Milkweed Gang – Milkweed attracts quite a few insects…even if it is an island surrounded by invasive plants!

New species of giant waterlily is the largest in the world – It has been growing in Kew Gardens in 177 years and in a herbarium in Bolivia for 34 years….always assumed to be the well-known species of giant waterlily named after Queen Victoria. The leaves can grow up to 10 feet wide…and support at least 176 pounds!

Toads surprise scientists by climbing trees in UK woodlands – Even when we think we know a species well…there are still surprises!

This New Species of Carnivorous Pitcher Plant Traps Its Prey Underground – In the rainforest of Borneo at elevations of 3,600 – 4,265 feet.

Ozone Hole — New, Large, Constant Ozone Hole — Appears Over Tropics – 7x larger than then Antarctic ozone hole!

Unlocking the secrets of the ancient coastal Maya – More than a decade of interdisciplinary work increasing the understanding of how these people lived and responded to rising sea levels and changing political/economic systems. And still more to be learned.

Gleanings of the Week Ending April 16, 2022

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.

Purple gallinule with chicks – I remember seeing an adult purple gallinule on a birding field trip in Florida. Aren’t the chicks cute? Little black fluffs.

Reproductive factors and dementia risk – Hurray! My life events skew toward reduced dementia risk…according to this study.

Macro photos reveal the often unseen beauty and diversity of slime molds – Hmmm…maybe I should hone my observational skills to find these on my next hike…attempt some macro photography of them.

As EV Sales Soar, Automakers Back Higher Fuel Standards – So glad that industry is finally onboard…projecting a ‘we can do it’ attitude. I’d rather society take action…build some optimism into our view about the future rather than being depressed by trends that seem dystopian.

Beginner’s Tips for Identifying Backyard Bird Nests – It’s the nesting time of year! Look…id…don’t disturb!

Ozone may be heating the plant more than we realize – We’ve been concerned about ozone in the upper atmosphere for years (hence the Montreal Protocol) but this study also points to ozone in the lower atmosphere (caused by chemical reactions between pollutants like vehicle exhaust fumes and other emissions) as contributing to climate change as well. Until now, we thought of lower atmosphere ozone as a health problem (I get headaches if I am outdoors on a high ozone day, for example). This research says that it also is contributing to climate change by affectioning ocean heat uptake.

American Lung Association Says EVs Save Lives – Good for our health….and also for the planet. I also noted that where I live now is in the American Lung Associations Tops 10 US urban areas at risk from airborne pollution…another reason to move away from this area!

New Technology Employed to Protect Pompeii – A four-legged robot used to gather data on structural and safety issues.

Flamingo that escaped from a zoo in Kansas is spotted once again in Texas 17 years later – The flamingo is a species from Tanzania….and must be a very lonely bird.

Brain charts for the human lifespan – Normative trajectories derived from over 100,000 MRI scans that allow quantification of individual variation. Figure 1 in the post can be enlarged by simply clicking on the image.

Gleanings of the Week Ending December 7, 2019

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.

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.

Critically endangered South American forests were planted by ancient peoples -- ScienceDaily – Forests of monkey puzzle trees were cultivated for their nuts and ability to attract game….they expanded as the population grew between 1,410 and 900 years ago. That was after an earlier expansion of the tree’s range caused by wetter climate from 4,480 and 3,200 years ago.

New Wind Farm Activity In Missouri Shows How States Can Leapfrog Over Natural Gas | CleanTechnica and Offshore wind energy is finally taking off in the US - Vox – Hurry for progress toward more sustainable energy!

Rising emissions of ozone-destroying chemical banned by Montreal Protocol -- ScienceDaily – New and unreported production likely in eastern Asia. Hopefully it will be stopped quickly and we can continue our progress in stabilizing and reducing the ozone-depleting gases in our upper atmosphere.

Top 25 Marine Birdlife – National Geographic Blog – I always enjoy bird pictures.

NASA Study Says Freshwater Shortages Will Be Biggest Challenge of This Century | CleanTechnica – As population increases along with industrialization and farming….more fresh water will be needed. We cannot afford to damage the supply beyond recover or use it unwisely.

Most popular vitamin and mineral supplements provide no health benefit, study finds -- ScienceDaily – Lots of studies say that food is the best way to get vitamins and minerals….this one goes a step further. It found that the supplements provide no health benefit!

Mapping America’s Aging Population - CityLab – The maps made this article for me: showing where Americans over 70 live (5% of the population in the county where I live now) and the death and birth in the use that categories whether population is naturally decreased on increasing by county (it naturally increasing where I live now).

Urban Plant Diversity – Cool Green Science – The theme of this article is to plant native species…less expensive, require less maintenance, and harbor greater diversity overall.

Social pursuits linked with increased life satisfaction -- ScienceDaily – This result seemed intuitive to me. As we get older and don’t have the level of social contacts we had during our career years, choosing activities that provide social interaction have to be done more consciously.

The State(s) Of Distributed Solar -- 2017 Update | CleanTechnica – Hopefully more states (utilities within the states) will jump on the bandwagon. There is quite an uptick since 2015 so the trend is in the right direction.

HoLLIE – week 3

The Week 3 of  HoLLIE (Howard County Legacy Leadership for the Environment) class day was last week and it was held at NASA Goddard like the second week. The theme for the day was continued from last week: “what informed citizens need to know about earth systems science.”

The first talk of the day as about ice sheets and included a discussion of the speakers trek to the South Pole last year. Check out her ICESat-2 Antarctic Traverse Blog (The first post is from December 4, 2017. If you want to start with that one and read in chronological order, scroll down to the bottom of this page until you get to ‘Heading South, to New Zealand and Beyond.’ Then after reading the ‘South Pole Station: The Last Stop Before the Traverse’ beginning at the top of the page, click on ‘newer entries’ to read the rest of the of the posts – and again start with the post at the bottom of the page and work up). She spent Christmas at the South Pole!

She recommended a book that I found could be checked out from Internet Archive when I got home: The two-mile time machine by Richard B. Alley. The book is about the annual rings of ice from cores drilled in Greenland and what they tell us about Earth’s climate over time.

The second talk was about the Land-Based Hydrology Cycle. This talk included what we can learn from satellites but also what measurements are taken on land too (and how much effort that takes…to get even sporadic data). With fresh water being so key to life – the very highs (floods) and very lows (droughts) are major impact all around the world.

The third talk was about the Black Marble project…about what we can learn from looking at the earth at night. Back in April there was good summation of the project – to create the images more frequently so that they could be used more even more applications (like short-term weather forecasting and disaster response): New Night Lights Maps Open Up Possible Real-Time Applications - https://www.nasa.gov/feature/goddard/2017/new-night-lights-maps-open-up-possible-real-time-applications; take a look at the map of India midway through the article and slide the vertical bar to the see how the northern part of the country was electrified between 2012 and 2016. There is more at https://earthobservatory.nasa.gov/Features/NightLights/.

The fourth talk was about how the Montreal Protocol saved the earth’s ozone layer. I knew the protocol concerned Ozone and CFCs….but didn’t realize any more history than that. The timing of a report that linked CFCs to ozone depletion just before the ‘hole’ was discovered in the ozone layer (a major change from measures of ozone for many years beforehand) over Antarctica made for a dramatic beginning to the conversation. It has been effective because governments engaged industry that provided substitutes (some transitional) that made it possible to move away from compounds that were ozone damaging in the stratosphere.

Next we visited NASA’s Scientific Visualization Studio – seeing some of their recent work on a wall sized screen. Here are some web versions of what we saw in the studio:
