Gleanings of the Week Ending December 31, 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.

Best of Mulitmedia 2016 – From The Scientist so most from the Life Sciences perspective. There is a display of infographics then links to the full stories. After that there are some videos. Quite a lot happened in 2016!

How to draw PACH – I am so pleased with this pattern. Remember the paper chains that children enjoy making with strips of construction paper? I remember making them…my daughter made them too. This is a Zentangle® pattern to draw them! It’s a lot easier than I thought it would be.

Happy Anniversary to Photo Ark! 10 Years, 6,300 Animals Photographed – The post is about Joel Sartore’s project to photograph the animals of Earth. Take a lot at the Photo Ark site as well!

Pregnancy leads to changes in the mother’s brain – I think most women acknowledge that there is a change…initially thinking it is just the effect of sleep-deprivation….and later realizing that part of the change is still there after the baby is sleeping through the night. For me – it not only helped me into motherhood, it also enhanced my ability to empathize with others. That made me a better manager and leader at work.

10,000-Year-Old Turf War – Even hunter-gatherers fought other groups of hunter-gatherers. I’m still following up on articles the students in the Osteoarcheology course on Coursera are finding.

Treasure Trove of Newly Discovered Species Includes a Newt that Looks Like a Klingon – My favorite is the first image (the Phuket horned tree agamid). Which one is yours?

“Celldance” Selections – 3 short cell biology videos: cell division, dendritic cell motion, and microscopy of living cells (within the body)

The strange effects of thinking healthy food is costlier – Evidently the health=expensive equation has a bigger impact on our perception (and purchasing) than objective evidence!

Phenology of Bee Genera: MidAtlantic States: USA – A slide show of graphs showing weekly counts for bees (by genus) in the area where I live from Sam Droege at the USGS Bee Lab….and links to other slideshows by the same author

Buying Experiences vs Buying Things – An infographic comparing spending choices (there is a link to expand the infographic…makes it readable). There are a lot of reasons that spending on experience adds to our happiness more than spending on things.

Gleanings of the Week Ending September 24, 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.

World Heritage in the High Seas: The Time Has Come – From National Geographic – pictures and a map of some potential places on the high seas that merit World Heritage status.

Historical analysis examines sugar industry role in heart disease research – A bit of disturbing history….is dietary fat the main culprit when it comes to heart disease? What about sugar and heart disease?

Gentians: part 1, part 2, part 3 – Elizabeth’s series on a particular flower….and not just in Maryland.

Brain’s stunning genomic diversity revealed – Huge insertions and deletions in DNA…surprise.

Scientists Baffled as Hundreds of Dead Horseshoe Crabs Wash Ashore in Japan – Sad…and no definitive reason yet. Theories being investigated include: parasitic infection or disease or oxygen shortage due to higher sea water temperature.

Between a rock and a hard place: biologists unearth sandstone-excavating bees – Bees are amazingly diverse. These are from the west and southwest in the US: Utah, Colorado, California.

Eggs make a comeback – A general overview of eggs in our diet. There is also a link to an article about ‘how to buy eggs.’

How our brain slows down the effects of aging – Elderly people develop a particular selective attentiveness. I wondered if, as we get older, we realize that we are paying more attention to details?

A Newly Explored Undersea Volcano is Teeming with Alien Life Forms – On Earth but very different than what we normally see.

How much do perfumes pollute? – A study of the canals of Venice….looking at the perfumes that are part of products we use daily like soaps, detergents, shampoos and other personal hygiene products. It turns out that the perfumes are in every sample…persistent for the 9 months of sampling. But what impact do they have on the environment – that’s still to be determined.

Merritt Island National Wildlife Refuge – Part 2

Continuing on from yesterday’s post about the Merritt Island Wildlife Refuge….

A plant community that becomes more evident the further south we drove is epiphytes with the Spanish moss being some of the most noticeable. But I took pictures of smaller ones as we walked around the boardwalk of the visitor center.

Flowers are always attention getters too.

Insects are even a bigger draw. Different kinds of bees were competing for flowers. The bumblebees are so big they usually drive the others away!

A long tailed skipper stayed put long enough for me to take a picture too.

The dragonflies looked similar to the dragonflies of Maryland.

We found a dead Polyphemus moth on the ground before we even walked into the visitor center. We perched it on a bush to photograph. It’s a male (large antennae to detect pheromone emitted by the females).

The seed pods on the button bushes in Florida look the same as the ones in Maryland.

And then there was a small tree in the pollinator with seedpods at various stages of maturity…and flowers too – obviously a legume.

When we got to the beach (the wildlife refuge abuts the Canaveral National Seashore), I noticed the sea grapes had color variation in their leaves and also had clusters of fruit.

These plants are planted on the dunes along the shore for stabilization.

There were a few gulls about but they were not as interesting as

The juvenile sanderling that seemed very interested in every piece of seaweed tossed up by the surf.

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.

Maryland climate and health report identifies state's vulnerabilities to climate change – Extreme weather, increased risk of foodborne illnesses, health impacts of extreme heat (hear attacks, asthma), increased accident risk from extreme precipitation.

Why vultures matter and what we lose if they’re gone – We have black and turkey vultures in our area of Maryland. I see them frequently and appreciate their place in the ecosystem – cleaning up carrion. Without vultures – other scavenger populations grow, often with negative consequences for human health.

Night Vision Problems and Driving – Something else that happens to most of us as we get older. I was surprised that the article did not mention astigmatism as more problematic at night if it is not corrected. I always notice my glasses not being quite right at night before I do in the daytime and it is usually the astigmatism correction that needs adjustment.

Colorful Watercolor Paintings of Radiant Trees in Nature – I couldn’t resist some eye-candy for this collection of gleanings since so many of the other items seem so serious.

New Zika Diagnostic – I’m glad they are making progress at diagnostics…now we have to make progress on prevention too since having a lot of infected people is going to be a public health crisis.

Test Your Sleep Smarts – How many of these did you know? The explanations of the answers are included…and sometimes contain links to more detailed information.

Team highlights ways to address global food challenges – Agriculture produces enough calories to meet basic human dietary needs worldwide…but one out of eight people in the world do not have access to sufficient food. This study presents a set of strategies to overcoming the challenges of providing food for the global population.

How Rising CO2 Levels May Contribute to Die-Off of Bees – Evidently an increase in CO2 often causes a decrease in the nutritional value of plants. A detailed study of golden rod pollen showed that pollen from plants in 2014 contained 30% less protein than pollen from 1842 (with the greatest drop occurring between 1960 and 2014). That’s important to bees that depend on goldenrod pollen for late season food. It’s important to us because nutritional value of crops like wheat and rice are similarly impacted by higher CO2 concentrations.

Too much folate in pregnant women increases risk for autism, study suggests – Another case where too much of a good thing is not good. A lot of the nutritional information is about minimal requirements. Supplements make it possible to get much higher doses than the minimal requirement. There appears to be a correlation with very high level of folate right after giving birth and the risk of autism spectrum disorder.

Meet the Bee Expert who Helped Invent the BioBlitz – I noticed this article just as we were finishing up the Belmont BioBlitz this week….and decided to include it in this week’s gleanings.

Gleanings of the Week Ending April 30, 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.

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.

Family Web Sites

My daughter and son-in-law are graduate students at University of Arizona and they have set up web sites. It’s one of the things grad students need to do as they prepare for the next step after grad school. Both of them have some outreach items that are of broader interest:

My daughter’s site has instructions for how to make a Pluto globe.

My son-in-law’s site has a video of buzz pollination (slow motions…taken with a high speed camera).

12 Machines that show modern farming isn’t the bucolic life you imagine – Wow! The way our food is harvested is mechanically amazing but also seems violent. I wondered if it was dangerous for the workers that tend the machines.

How do you prepare for the isolation of space? – Using Antarctica as a training location for space missions.

What’s the difference between reindeer and caribou – It’s past Christmas – but I didn’t see this article in time. Evidently they are the same species! But reindeer show the impact of domestication.

New kind of thermal vent system found in Caribbean – They are formed of talc rather than sulphide minerals.

How Juneau handles its garbage – They ship their recyclables south via barge and try to minimize the garbage that they landfill nearby (although space is limited). Other municipalities may not face quite the transportation challenge that Juneau faces (no overland transportation from the city) but the long term issues toward sustainability are the same.

Photography in the National Parks: Your Armchair Guide to Mesa Verde National Park – It’s been over 30 years since I was Mesa Verde; these pictures encourage me to plan another visit.

Is This Snowy Wonderland Or The World Inside A Petri Dish? – Cut paper versions of bacteria and other organisms

Our Energy Transformation in 2015 – Even with low oil and gas prices, we are still shifting way from fossil fuels. Oil consumption in the US is on a downward trend and the adoption of clean energy hit record rates in 2015. For the first time in history, carbon emissions fell even as the world economy grew.

US Wild Bee Populations Waning – Not good. Most of our agriculture needs pollinators and yet these are the very areas where the wild bees are being decimated.

New Species Abound – And these are new species that are large enough to be visible. What about all the soil microbes that we know so little about? It’s time we internalize that we really don’t know all the species on our planet.
