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.

Mysterious Winds Cause Rapid Melting of Antarctic Ice – Fohn winds….a warm wind that may be responsible for calving ice shelves. And some of their most impressive heat waves come in the dead of winter, eroding glaciers at a time of year that no one thought possible.

Electron Micrographs Get a Dash of Color – And they used red and green…so the images looks very Christmassy!

Ancient Royal Boat Tomb Uncovered in Egypt – Found while investigating the tomb complex of 12^th dynasty King Senwosret III, located in southern Egypt. The walls of the tomb covered with sketches of boats.

What it’s like to sail a giant ship on Earth’s busiest seas – Part of the BBC’s Future Now series.

Cuba’s Underwater Jewels are in Tourism’s Path – Gardens of the Queen National Park: keys, mangrove islets, and reefs about 50 miles off Cuba. Cuba limits the number of divers and fishermen allowed to visit but could face pressure to increase access.

Birds have skills previously described as ‘uniquely human’ – Caledonian crows use tools, scrub jays remember past events and act accordingly, pigeons can be trained to recognize patterns of letters (words). But they may be processing stimuli differently than humans. Maybe no two species are the same but the brain is often adaptable enough to find a means to meet the needs of the animal.

The most Visual Science Textbook You’ve Ever Seen – History of Evolution….and images of example along the way.

The Chemistry of Turmeric – Fluorescence, Indicator, and Health Effects – The post includes an infographic but the short video is worth watching (rather gathering materials to do the experiments yourself).

Interactive: See How Global Health Has Changed Since You Were Born – A fun way to learn a bit about the history of global health.

Urban Forests: what city trees do for us and what we should do for them – Trees in the city...cost effective and good for our psyches too.

Wild cat brains: An evolutionary curveball – Cats are different….the size of their frontal lobes is linked to their social natures in a different way that people and monkeys. Cheetahs (social cats) have small frontal lobes and leopards (solitary cats) have large ones.

Jumping Worms: The creepy, damaging invasive you don’t know – I saw this article and have now see other reference to this invasive species. Aargh! I looked at worm pictures from our Belmont Bioblitz and was relieved that the worms we found were not this species!

Significant Bronze Age city discovered in norther Iraq – A dig only 45 kilometers from territory controlled by Islamic State!

The Lost History of South Africa – Rock art of the San people...older than the cave site in France.

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.

Sunflowers Track the Sun, Like Solar Panels – The behavior was reported in scientific literature in 1898. Now there are studies to understand how the plants do it biochemically and physically. I also liked the picture at the beginning of the article.

Ancient air pockets changing the history of Earth’s oxygen – Ancient air trapped in rock salt shows that earth’s atmosphere contained 10.9% oxygen 813 million years ago….about 300 million years earlier than previously thought. It’s not as much oxygen as in our current atmosphere but a lot of organisms did develop during this time period when there was less oxygen.

Healthy Eating, A to Z – How many of these 26 do you already know?

30 Reason Your Next Car Should Be Electric – I’ve been thinking recently that my next car will probably be electric. It’s good to see that there are a lot of reasons this it is a good idea! Item 29 on this list (kids and grandkids and great-grandkids) is high in my rationale.

Closest Living Relative to the Dodo Dazzles with Vibrant Iridescent Plumage – A little eye candy and interesting biology in one article.

As lab-grown meat and milk inch closer to U.S. market, industry wonders who will regulate? – A complex issue and it’s not clear if the USDA or FDA will be responsible. The technology is moving forward quickly in the agricultural biotechnology arena. It is challenging to understand it well enough to propose appropriate regulations for public health and safety.

Newly discovered fossils break record, dating back 3.7 billion years ago – Evidence of microbial life found in Greenland (where there are some of the world’s oldest sedimentary rocks). Another article on the same topic from Science Daily can be found here.

Study assesses climate change vulnerability in urban America – Our area got a wakeup call in this arena with the damage to Ellicott City from recent flooding. It happened very quickly, with very little warning. The planning for infrastructure, human populations and local concerns when it comes to climate vulnerability is in its infancy in many parts of the country.

What’s changed in genetic since your high school biology – My high school biology was at the very end of the 1960s….a lot has happened since. I’ve taken some classes to update myself but it is always interesting to see a summary of the high points in articles like this.

Maintaining healthy forests takes more than planting trees – What about massive wildfires and invasive forest pests. A healthy forest is a diverse mix of young and old trees, dead trees, and openings. Forest scientists are realizing that homogenous and overgrown forests need to change. A follow-on post talked about technology for foresters in the field.

Humans Never Stopped Evolving – A discussion of more recent human traits.

Strange Minerals from Siberian Mine Are Unlike Anything Found in Nature – Naturally occurring metal-organic frameworks (MOFs)?

Toxic blue-green algae adapt to rising CO2 – This does not bode well for fresh water supplies as the CO2 levels rise.

Protein Packed Produce for Meatless Monday – Meat is not the only food with protein…think veggies too: peas, broccoli, mushrooms, Brussels sprouts, asparagus, artichokes, spinach, kale and cauliflower!

The Best Schools in the World Do This. Why don’t we? – An peek into a report from the National Conference of State Legislatures.

The Neanderthal in the Mirror – A short history of our understanding Neanderthal skeletons....seeing them as more and more ‘human’ over the past century.

Kathleen Clemons Instagram – Instructor for some of my favorite Creative Live classes….sharing photos taken with her iPhone. Beautiful images…mostly flowers.

Milkweed Meadow posts from What’s That Bug? – A cluster of milkweed plants is a great place to look if you want to find insects. This series of blog posts is focused on typical insects you’ll find.

How to Prevent Mosquito Bites – I am paying more attention to articles like this since Florida is reporting more Zika cases…and I’m planning a trip to Florida this fall.

Did We Used to Have Two Sleeps Rather Than One? Should We Again? – Maybe we were not meant to sleep all the way through the night!

The New Green Grid: Utilities Deploy ‘Virtual Power Plants’ – Sprawling networks of independent batteries, solar panels, and energy efficient buildings tied together and remotely controlled by software and data systems….a trend boosted by California’s natural gas shortfall that will become the norm?

Third Severe Flash Flood Hits Maryland/Delaware – The Ellicott City flash flood on the evening of 7/30 (just a week ago) was close to home…lots of destruction of the history main street.

Mystery Mechanisms – Many drugs appear to work…but we don’t know exactly how they work. This post discusses lithium, acetaminophen, and modafinil.

Why do we get bags under our eyes? – No stunning revelations in this article – but interesting that there are multiple reasons that people get them.

Awesome Video Compares the Size of Different Plants and Stars in the Universe – The video is a sequel to Star Size (and distances) which is also included in the post.

Earth’s ‘Annual Physical’ Lists Symptoms of a Hotter World – State of the Climate in 2015 from NOAA (and internationally peer reviewed). The indicators of a warming planet that are: greenhouse gases highest on record, global surface temperature highest on record, sea surface temperatures highest on record, global upper ocean heat content highest on record, global sea level highest on record, extremes were observed in the water cycle and precipitation. The post includes links to download the report – chapter by chapter.

The machines that run the internet – A short film.

A Murder of Crows: When Roosting Crows Come to Town – We don’t have large number of crows in our area – but we are seeing more than we were a few years ago when West Nile Virus killed so many of them.

Picky Eaters: Bumble Bees prefer plans with nutrient-rich pollen – The protein to lipid ratio makes a difference to bumble bees!

Ocean Acidification and Chemical Signaling – How ocean acidification impacts chemical signally of shell fish…an infographic about research on peptides that are involved in detecting predators, homing, and reproduction.

How one of history’s bloodiest wars eventually saved lives – By the end of World War I, combatant deaths has reached 10 million. Twice as many were injured. Post-traumatic stress disorder was recognized for the first time – called ‘shell shock.’ Blood transfusion, oxygen and treatment on the front lines became the norm. See some of the devices developed and used during that time period in this post or at the Wooded exhibition at London’s Science Museum.

Floating Solar: A Win-Win for Drought Stricken Lakes in the US – Will this idea become reality? It seems that in places where water is scarce that reducing evaporation and producing power at the same time would be a positive thing.

Humans artificially drive evolution of new species – Human drive extinction but also speed up evolution of new species as well. For example – a common house mosquito has evolved into a new species that thrives in subterranean environments – like subway stations; it can no longer interbreed with its above ground ancestor species.

Beyond Sightseeing: You’ll Love the Sound of America’s Best Parks – A project to record the (non-human) sounds of national parks.

Boosting potency of broccoli-related compound for age-related macular degeneration – Macular degeneration impacted the last few years of my grandmother’s life and I still notice articles about current research on prevention and/or remediation…. macular degeneration might happen to many of us as we get older.

Vanishing Act: Why Insects are declining and why it matters – Another example of the importance of biodiversity to our future…and the future of the planet.

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.

How dirty is your air? – Based on this article – I am trying to get in the habit of turning on the vent fan when I am cooking….and opening some windows when the outdoors temperature is pleasant.

Serious Putty – A clay with antimicrobial properties…even against resistant strains! More research is needed – but it is exciting that this could be a totally different mechanism for fighting infection that the current antibiotics on the market.

Snow in Vietnam and Other New Climate Patterns Threaten Farmers – This is from the Business Report section of the MIT Technology Review. The article focuses on farmers in Vietnam in an area that got snow for the first time in their life time (and historically) last winter and how weather patterns are impacting their finally honed rhythm for crops. It would be interesting to hear stories from farmers around the world. Climate is changing globally – but not always in the same way.

Sunflower Spirals: Complexity Beyond the Fibonacci Sequence – The results of a crowd sourced look at sunflower spirals: 1 in 5 did not conform to the Fibonacci Sequence. Some of those non-conformers approximated it and others approximated more complex mathematical patterns! Either way – I like the look of sunflower spirals.

Genome Digest – Recent findings of genomic research on giraffes – carrots – zebrafish and gar – herring – Atlantic salmon. A lot has changed since I got my biology degree in the 1980s.

Seeing the Inevitable, companies begin to adapt to climate change – Most companies are aware that climate change is likely to affect their future but are not planning for it with any consistency or depth. Those furthest along are those already dealing with climate change on a daily basis: agriculture and insurance. Ikea and Ford are two companies used as examples in the article.

Tranquil Impressionist-Style Paintings Showcase Beauty of Natural Parks Around America – Eye candy for the week!

Life in the Dark – Photographs of sea and cave creatures that live their whole lives in the dark.

C40’s Executive Director Mark Watts on how mayors are changing the way we think about food – Area of focus are food: procurement, production, distribution, and waste.

Frog, Turtle Species Being Reintroduced to Yosemite Valley – The California red-legged frog (the largest native frog in the western US) and the western pond turtle are being reintroduced to lake, river and meadow habitats.

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.

New Climate Spiral – A visualizing of average global temperatures. Do this little exercise with the graphic – if you live to be 100, how much hotter will the planet be than when you were born? For me – it is about 2 degrees…almost 3 degrees hotter than in 1850.

Climate change poses threat to World Heritage sites - Melting glaciers, rising seas, increasing wildfires and harsher droughts….these could diminish the value of protected sites and even make them unsuitable for World Heritage designation. That would have a domino effect into local economic development, in particular the tourism sector.

Bionic leaf turns sunlight into liquid fuel – And at a higher efficiency than the fastest-growing plants!

Washington grapples with a thorny question: What is a GMO anyway?  and Report: Still lots to learn about GE Crops – The terms GMO and GE are inadequate to describe the complexity of what is happening now. Both of the articles are about a recently released report on the situation.

What’s up with microbeads – Plastic microbeads cause long term health effects in our waterways (streams, rivers, lakes, oceans). There are US regulations that are being phased in over the next few years to require that manufactures no longer make products with microbeads but prior to that individual can stop purchasing the products. I’m going to check packaging to avoid products with microbeads; the key ‘ingredients’ to avoid are polyethylene, acrylate copolymer, and polypropylene.

Top 25 informative maps that teach us something uniquely different about the world – Displaying data by location makes for easy comparison. If you did not already know about the US and paid maternity leave – the map makes if very clear – not something to be proud of.

Teenage brain on social media – It’s always been true that teenagers are better at doing than not doing (i.e. inhibition develops more slowly than other forms of cognition). This study was about how that translates into the social media realm.

Antibiotics from scratch – Drug resistant bacteria are becoming more and more problematic. This research is a ‘bright spot’ in developing antibiotics to stay ahead. No one wants to go back to the time before antibiotics.

Arctic Foxes ‘grow’ their own gardens – From Alaska’s Arctic National Wildlife Refuge.

Image of the day: don’t eat me – Usually moths are rather drab – not this tiger moth!

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.

Exposure to chemicals in plastic and fungicides may irreversibly weaken children’s teeth – Another reason to pay close attention to Bisphenol A (BPA) and Vinclozolin in diets of children. Based on this study – this is not something that fluoride treatments or supplements would overcome.

Identifying Wildflowers: part one, part two, part three, part four – From Elizabeth’s Wildflower Blog. This series include a lot of practical advice for identifying wildflowers in the field (and confirming after you get home). I’ve been following Elizabeth’s blog since I was in Master Naturalist class with her --- learning about wildflowers.

Language of Women versus men – An analysis of language in Facebook messages shows that women use language that is warmer and more agreeable than men. The graphic associated with the study is worth a look.

Mysterious Cave Rings show Neanderthals liked to build – And more than 1,000 feet into the cave where it would have been very dark.

Kazakhstan’s treasure trove of wildly-flavored apples – Forests where apple trees are the predominant species!

Tidal Troubles in the Mid-Atlantic – A place where the sea level is rising at a much faster rate than almost anywhere in the US (except parts of Louisiana and South Florida)…and an explanation that goes back to the last ice age which left the area with a ‘fore-bulge’ – so the land is sinking from that then the ocean is rising too! The net is a predicted sea level rise of 3 feet around much of the Mid-Atlantic by 2100.

Three perfectly blue days at Crater Lake National Park – I haven’t been to this national park – yet. This is an article to look at again when I finally get around to planning the trip.

Swarms of Octopus are taking over the oceans – Cephalopods as ‘weeds of the sea’!

The Cactus Smuggler: Are Desert Plants Being Loved to Extinction? – Not a good trend and very difficult to change.

Low-salt diets may not be beneficial after all – Evidently the prior recommendation for low-salt diets was not based on data – the old recommendation was ‘popular thought’ rather than based on objective evidence! High-salt is still bad….but average (between 3 and 4 grams per day) is best!

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.

Nanoscale solutions for hospital acquired infections – Antibiotic-resistant pathogens are problematic…and racing to find new antibiotics is getting harder all the time. Seeing different solutions – like these (click in the red circles to see the description) is reassuring.

Umami Flavor on the Rise – The ‘pleasant savory taste’ of soy sauce, hard cheeses, and mushrooms or nutritional yeast….but how to get the flavor without high sodium.

Changing the world, one fridge at a time – What can we do about food waste? The problem is in the production side in the developing world and the consumer side in the developed world…so in the US, it is in each of our refrigerators and pantries. I’ve gotten better over the past few years and rarely have anything spoil. I also dry orange peels instead of putting them into my compost!

Green light for plant-based food packaging – Part of the solution to food waste? Based on this story from Science Daily – I’m not sure this one is ready for prime time.

How Safe is Your Drinking Water? – A well-organized article with some tips on how to find out more from Berkley Wellness.

Enthusiast Builds Website to Collect, Share Free National Park Maps – Find it here. This is a site to bookmark and check when you are planning a trip to any National Park.

A Surprising Look at Crow Family Life – We are seeing more crows this year – recovering to the numbers from before West Nile Virus killed so many of them. I welcomed hearing about cooperative breeding among crows in this article (and maybe it includes the blue jays too).

9 Dangerous Beauty Trends – How many of these did you already know about?

How a Cancer Drug has saved people from going blind – My grandmother was blinded by macular degeneration so I’m always interested in the ongoing research to prevent or treat it.

Kids win another climate change lawsuit – A Superior Court judge ruled in favor of 7 young plaintiffs ordering the Washington (state) Department of Ecology to promulgate an emissions reduction rule by the end of 2016 and make recommendations to the state legislature about how to reduce the state’s greenhouse gas emissions in the 2017 legislative session. Similar legal action is pending in North Carolina, Colorado, Pennsylvania and Massachusetts.

Winners of the 2016 Audubon Photography Awards Celebrate Diverse Birds of North America – These are birds in action – not posing for a photograph!

Four Ways to Explore the News through Maps – This post was for teachers (and via them to their students)…..but could be interesting to just about everybody. It is a different way to access news.

Pulling it all together – I took a Systems Biology course from Coursera last year and realized the need to integrate what has been compartmented for study – a needed simplification until recently. Systems Biology requires computers and models that have a lot of similarities to those for research into global weather or astrophysics. This article highlights 4 strategies for hunting new cancer targets.

Dreamlike Watercolor Paintings of Iconic Skylines Around the World – How many of these skylines do you recognize?

Fructose alters hundreds of brain genes, which can lead to a wide range of diseases – Interesting research done with rates. Fructose was found to impair memory but rats given DHA (an Omega-3 oil) along with the fructose performed comparably to rats that were not on the fructose diet.

Satellite maps shows explosion in paved surfaces in D.C. region since 1984 – I moved to the Washington DC area in 1983. A lot has happened since then. On the ground, the increase in paved surfaces has not kept up with the number of cars trying to get from one place to another.

Here’s how climate will affect what we eat – Several alarming items from this post: “High quality chocolate will be less available in the future, and if you want it, you’ll have to pay a lot more for it” and crops that grow in small geographic areas (most things besides stables) will be most severely impacted. It appears that diets will become more standardized (maybe boring too).

A Breathtaking view of the World’s Oldest River System – The New River Gorge in West Virginia…maybe a vacation destination?

Mapping the National Parks – Topographic maps, national scenic trails, geologic maps, and remote sensing…there is a lot of information best displayed on a map!

Ancient city of Pompeii unveils restored homes – The results of 12 projects done by a 2012 partnership been the EUs European Commission and Italian authorities. I was glad to see that some restoration work is being done; the many tourists take a toll on the site.

The Best of Cool Green Science: Birds & Birding Edition – Pointers to 10 birding posts from 2015 on The Nature Conservancy web site.

The Year in Food: Artificial Out, Innovation in (And 2 More Trends) – How many of the trends have you noticed? Some of the labeling (‘all natural’ and ‘clean’) is not well defined but it is pretty clear that consumers are voting with the dollars – which forces the food system to respond. I know that we don’t go out to eat as often as we used to, do most of our grocery purchases around the periphery of the store, and compost the small amount of food parings we don’t eat.

Mapping 260 years of Global Carbon Emissions – A short video map of the world that shows the global emissions from fossil fuel burning from 1750-2010.

Chocolate + Fresh Fruit = Easy, Impressive Vegan Desserts – All of these desserts look good to me….and they are on the healthier end of the spectrum for desserts!

These Are Our Favorite Earth Images of 2015 – The image of earth from space – awesome!

Appliance upgrades that save the most water, energy and cost – Thought provoking article. Sometimes deciding the ‘best bargain’ is more complex that we realize. One surprising result: one of the best appliances to update for water efficiency was the gas furnace, not the more intuitive shower head or dishwasher, because of the water associated with producing energy.
