Gleanings of the Week Ending August 20, 2016

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.

Sweat: How to Keep Your Cool – This post seemed to fit with the hot, humid weather we’ve been having since late July here in Maryland.

How millennials are shaping the future of work – I think it is more than just millennials that want these things. I can remember wanting the latest tech for my entire career….and when I didn’t always get it, being frustrated. I remember in the 1990s wanting a laptop rather than a desktop PC as my primary work machine because I was traveling a lot…and being told that laptops could be checked out when I traveled but were not available for in-office use!

From Tree to Shining Tree – The wood-wide-web that is the forest under the forest…made of roots and fungus. A Radiolab Podcast just over 30 minutes long.

Fresh look at burials, mass graves, tells a new story of Cahokia – Skeletal evidence was re-evaluated. The publications in the 1960s assumed all the skeletons were male….but they were male and female. And the motifs with the graves have to be interpreted differently too.

Pressure Mounts to Reform Our Throwaway Clothing Culture – I’ve been donating clothing for a long time…but this goes a step further.

Questioning the Presidential Candidates on Science – 20 questions sent to the candidates with answers requested by September 6^th. I’m interested in seeing those responses.

Plastic bag usage has 85% decrease in England after government starts charging per bag – Hurray for England. Wish we were doing more in the US to reduce plastic bags. I’ve been using usable bags for the past few years but there are still a lot of people that aren’t.

Wind power fiercer than expected – I was surprised that evidently there has not been a lot of research on the wind patterns at turbine level over the east coast where a number of wind farms are being planned….including off Maryland’s coast.

The Secret Lives of Horseshoe Crabs – We often see horseshoe crabs on Chesapeake Bay beaches…this was a good post about their life cycle and the current challenges to the species.

New Wondrous Photos of the World’s Beautiful Diverse Fungi – Nature photography and eye candy all in one!

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.

Microplastics – a cause for concern – Lots of questions…only a few answers. It seems like there have been a lot of articles on the topic recently.

Biodiversity has fallen below ‘safe’ levels – We don’t actually know what the ‘safe’ limit is…but do we want to actually find out when there is no recovery? This report is pointing out that 58% of the world’s land has lost more than 10% of its biodiversity. 10% biodiversity loss is the value that was deemed ‘safe’ limit within which ecological function is relatively unaffected.

Early preschool bedtimes cut risk of obesity later on – Another good reason for preschoolers to be regularly tucked into bed by 8 PM!

Electricity generated with water, salt and a 3-atoms-thick membrane –

Splattered Watercolor Paintings Capture the Beautiful Vibrancy of Delicate Flowers – I like just about everything botanical…eye candy too.

Jupiter and Juno – What do we already know about Jupiter’s chemistry? – An infographic from Compound Interest – background for understanding what we already know about Jupiter’s chemistry and what we hope to learn about it from Juno.

From the Earth’s Oceans (images) – From The Scientist. These images reminded me of how different live in the oceans really is than what we experience on land.

Photo of the Week (from The Prairie Ecologist) – Actually – several photos…of little things that thrive in the prairie.

How Type 2 Diabetes Affects the Brain – Two recent studies that have increased our understanding of the cognitive effects of diabetes – refining not only the description of effects but also how the structures of the brain are changed by diabetes.

Yeast emerges as hidden third partner in lichen symbiosis – Wow! This is something I’ll include in my talk with hikers about lichen. They are always fascinated that lichen grows on rocks and tree trunks….that it’s a combination of fungus and algae…and now we can add that there is usually a yeast there too that is often the part producing chemicals to defend the other two organisms in the symbiotic relationship (and sometimes it changes the appears of the lichen too)!

6th Graders at Storm Water Engineering

Last week I volunteered during a 6^th grade field trip to Belmont Manor and Historic Park. It was the last of the Middle School spring field trips there. The field trips activity were a mixture of history, technology, and science. My station for one of the day was about storm water engineering. The majority of the students realized that Belmont is on a hill and that the rain water would run downhill to the Patapsco River into Baltimore Harbor then to the Chesapeake Bay and then the Atlantic Ocean. Each team of 4-5 students was given a paint tray with a mound of earth at the high end of the tray as a model for what happens to storm water. They could add sticks, stones, and dry grass in any way they wanted to slow the flow of the water when it ‘rained’ (via a watering jug) on the soil. After 10 minutes of engineering by all the teams, the teams did a short description to the whole group and then the ‘rain’ came as everyone watched.

A surprising number of teams did not think to cover the soil at the top of the tray. It ‘eroded’ when the rain came down and often resulted in fast water runoff and the water was muddy too.

Some of the teams did cover the soil and used rocks and sticks to hold grass in place both over the soil and rocks; the grass turned out to be very absorbent. The water took a long time to get through to the bottom of the paint tray….and was generally clear.

As I watched the teams decide what they were going to do, implement their design, present their design, and then test it, I was intrigued by the ‘light bulb’ moments of learning that were visibly occurring all along the process.

As I walked back to my car after the last field trip – I took a picture of the bald cypress down near the pond – the tall grasses waving in the misty day…. feeling happy to have been a part of the field trips for middle schoolers at Belmont.

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.

Hawai’I at the Energy Crossroads – A case study about the issues with how we produce electricity – now and into the future.

“Top tips for men juggling a successful career and fatherhood” hilariously nails how sexist the advice given to working women is – For anyone that doubts that gender bias is still quiet prevalent in the workplace.

Ancient tsunami evidence on Mars reveals life potential – Evidence of cold, salty oceans on Mars (the image of Mars was produced using Google Earth!)

Restoring an Ancient Nursery for Atlantic Sturgeon – These fish can reach 14 feet in length and weigh 800s pounds – a species that has been around since the dinosaurs. In the 1890s, caviar from Delaware River sturgeon was a thriving enterprise. Within a decade, the population of sturgeon fell to 1% of its historic numbers. Even with a moratorium on sturgeon fishing in the 1990s, the fish were not recovering due to ship strikes, channel dredging, and poor water quality. Now – with focus on dissolved oxygen, salinity, and flow conditions….and understanding the extent of spawning and nursery habitat in the freshwater portion of the river…slow recovery is beginning.

Antibiotics that kill gut bacteria also stop growth of new brain cells – Another reason antibiotics should not be overprescribed….and that we look for ways to resolve an infection that does not kill gut bacteria.

Wildlife is where you find it – A reminder that the natural world often survives even in a very man-made environment…and to be observant enough to notice it.

Bright light alters metabolism – Blue-enriched light in the evening seems to be problematic….will electronic devices of the future modify the type of light they emit based on time of day to help us stay healthy?

State of North America’s Birds Report Released to Commemorate Centennial of the First Migratory Bird Treaty – Birds connect our continent and some progress has been made. There is still a lot to be done. Individual actions like choosing sustainably created products, preventing bird collisions with windows of our houses and office buildings, and participating in bird related Citizen Science project (like eBird) make a difference.

10 Overlooked Wildlife Experiences in our National Parks – Sometimes small creatures that make their homes in National Parks are just as memorable as the scenery.

Toothpaste Tips and Myths – Toothpaste comes in lots of different formulations. Educate yourself about the good – and not so good – aspects of some of the benefit claims.

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.

Sharing a Passion for ‘beautiful’ bees – A nature photographer’s project to tell the story of North America’s native bees. There is some information about how he gets his images without stressing the bees too.

Getting to the Root – 18 genes are related to hair related traits --- but we are only beginning to understand how they work.

How do we get our drinking water in the US? – With Flint, Michigan’s water problems, awareness is increases across the country that we should not take our drinking water ‘goodness’ for granted. For a more chemistry perspective – take a look at Water Treatment – from Reservoir to Home from Compound Interest.

Sugar: The Benefits of Cutting Back – The results of a study involving children and teenagers.

7 Tips to Reduce Food Waste (and Save Money) – Nothing truly new in this list…but all good ideas. Now to just apply them all the time.

Genetic Resilience – A study of half a million human genomes, reveals 13 adults that had mutations for 8 different severe childhood genetic disorders…yet had no reported signs of the disease. We have a way to go in understanding how genes work as a system; none of them work in isolation and our studies of them in a standalone fashion is a simplification too far.

Are hazardous chemicals in your cosmetics? – The 4 to look for and avoid are: phthalates, parabens, triclosan, and oxybenzone because they interfere with the body’s natural hormones.

Thyroid tumor reclassified to curb over diagnosis of cancer – The detection of tumors has outpaced the research about what tumors need treatment versus those that are relatively benign. This is a case where a type of thyroid tumor previously classified as ‘cancer’ is being reclassified as non-invasive and with a low risk of recurrence. Are there more tumor types that patients are worrying about now that will eventually be reclassified along these same lines?

America’s Ten Most Endangered Rivers of 2016 – The one near me is the Susquehanna but the 10 rivers on the list are all across the country.

Dirty Dozen Update! Fruits and Veggies Worth Buying Organic – The latest list from the Environmental Working Group.

Microscopic Iridescence of Peacock Feathers – I’ve always been fascinated with peacock feathers. This article zooms in closer to the feathers and uses photo stacking to get the depth of field so that the structure is in focus.

Longer maternity leave is better for infant health – The article is about a study done comparing outcomes of paid maternity leave in low and middle income countries around the world….but toward the end, there is a reminder that the US is one of the few countries in the world that has no paid maternity leave mandate. Aargh! I was lucky enough to work for a company that paid 8 weeks of maternity leave when I had my daughter; it was considered a medical leave.

Disparity in Life Spans of the Rich and Poor is Growing – Wealthier Americans live longer than poorer Americans…and the gap is getting larger. For women born in 1950, the delta is about 12 years.

Soil: Getting the Lead Out – Our soils contain our legacy --- which includes lead from gasoline and paint over many years before it was banned in recent decades. There is remediation, but one has to detect the problem

Genetically engineered immune cells are saving the lives of cancer patients – It’s still early….but the initial result are very promising.

The Four Biggest Hazards Facing Monarch Butterflies, and how you can help – Make sure to get to the end of the article for how each person can make a difference for monarchs.

Real Animals that you didn’t know existed – Hooray for biodiversity!

Could new class of fungicides play a role in autism, neurodegenerative diseases? – Yet another reason to stick with organic vegetables and fruits. The particular fungicides in this study are used on conventionally grown leafy green vegetables.

The Rogue Immune Cells that Wreck the Brain – It appears that microglia might hold the key to understanding not just normal brain development but also what causes Alzheimer’s, Huntington’s, autism, schizophrenia, and other intractable brain disorders.

How NASA turns astronauts into photographers – I’m glad the astronauts have made time for photography!
