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.

Skeleton found in Clare cave reveal a tragic life story – The skeleton found in a cave was analyzed and found to be a boy 14-16 years old at time of his death in mid-1600s. He had endured near starvation conditions for all his life. The space he was found in was just large enough to crawl into…and I wondered if he intentionally went to the cave to be alone when he died.

The Chemistry of LED Lights – We are seeing so many LED lights in Christmas displays. Here’s the tech details behind the brilliance.

Skin proteins reveal how mummies died – Three mummies analyzed. Based on the proteins found, one might have died of tuberculosis and another from pancreatic cancer. The third one had been interred in a hollowed out log and exposed to the elements over time; the proteins had degraded and could not be identified for that one.

An Unlikely Renaissance of Appalachian Elk – Outside Grundy, VA – in a former surface coal mine, now grass covered…a place for reintroducing elk to the east coast. There are places in Kentucky and Great Smoky Mountains National Park too!

Hard of hearing? It’s not your ears, it’s your brain – Evidently, many older people find understanding speech difficult even when their hearing (the ear part) is fine.

Risks of Managing Prairies Exclusively for Plants – Plants are a part of the environment that are sometimes the easiest to see and ‘manage’ ---- but that might not result in a health system. It’s a more complex situation and we often don’t have the depth of understanding to build a sustainable environment that is comparable to the ‘natural’ one that once was there.

Futures Ghosts? Wildlife on the Brink of Extinction – Have you heard of these animals before…and realize they are near extinction? The rusty patched bumble bee has just recently been ‘in the news.’

Can wild seeds save us from food apocalypse? – A little history…a little status report…how and why seed banks are needed.

‘Shadow method’ reveals locomotion of secrets of water striders – We often point out water striders to our elementary school hiking groups. They are always intrigued by the insect that can ‘walk on water.’

In new ozone alert, a warning of harm to plants and to people – Snap beans, milkweed, coneflowers, and other plants turn brown and sickly when ozone occurs at ground level – becoming bio-indicators for this pollutant. While pollution controls have brought down the peak ozone levels, the background levels have been increasing.

Photo of the Week – October 14, 2016 – Fall photos from The Prairie Ecologist.

The amazing cloud cities we could build on Venus – With ‘going to Mars’ being so much in the news recently, it was interesting to read about why Venus might have some advantages over Mars for colonialization.

Hypothyroidism symptoms linger despite medication use, normal blood tests – A study that shows that not everyone gets symptom relief from the current standard treatment with levothyroxine…and that the medical community is finally beginning to notice.

10 Great Butternut Squash Recipes for Fall and Winter – I like butternut squash so I am always on the lookout for good recipes. Most of the time butternut squash, pumpkin and sweet potatoes can be substituted for each other in recipes too!

Cicada wings inspire antireflective surfaces – Another example of getting materials engineering ideas from nature.

Skip the Math: Researchers Paint Pictures of Health Benefits and Risks – It’s hard to understand the trade-offs involved in many tests and medicines. I was glad to see this attempt --- and hope that doctors become more savvy too.

Calcium supplements may damage the heart – There are growing concerns about potential harms of supplements…and this study about calcium is one example of studies behind that growing concern. The analysis of 10 years of medical tests on more than 2,700 people revealed that while a diet rich in calcium is protective…taking calcium supplements may increase the risk of plaque buildup in arteries and hear damage!

Why sentient tools will be catastrophic to the job market – Sentient tools (example: autonomous cars, warehouse workers, delivery people) are not as ‘sci-fi’ as they used to be. We see early examples of many of them. They will become increasingly able to outperform humans in a variety of jobs. Think of the ripple effect of autonomous cars – on insurance company revenues, on emergency services, on taxi drivers!

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.

How comedy makes us better people – Analyzing humor’s role in our culture – in much the same way as we analyze intelligence.

Exploring How and Why Trees ‘Talk’ to Each Other – An interview with Suzanne Simard.

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.

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.

Edible food packaging made from milk proteins – I’m not sure how this works to reduce packaging since to be edible it would have to stay clean (i.e. another layer of packaging?). Still – it would be great to reduce the amount of hard-to-recycle plastic packaging.

Zika Infects Adult Neural Progenitors Too  and How Zika infects Mother and Baby – Two articles from The Scientist. Zika is a hot research topic right now…and a public health concern.

Research priorities for the field of atmospheric chemistry – The development of a predictive capability to provide foresight into the consequences of rapid changes in the Earth system is need to help in preparation and decision making. Right now the field is focused on observing, learning and discovering for fundamental understanding…so there is data to support attempt to develop a predictive capability.

New Virus Breaks the Rules of Infection – The Guaico Culex virus that infects mosquitoes has 5 genes and each gene is individually packaged. A mosquito cell has to have 4 of the 5 packages to be infected. The 5^th package may cause the infection to be potent. Once again – a case that shows how little we really understand about life on Earth.

How Aluminum Changed the World – A little history for the week.

Wildflower Wednesday: Chicory – Like the author of this post – I like chicory. The blue color redeems it from being considered a weed for me!

Invasive Species Spotlight: Canada Thistle – Evidently it was introduced accidently to North America in the 1600s!

Photos of Frozen Flowers Capture the Paradoxical Beauty of Preservation and Destruction – Eye candy for the week….maybe an idea for some photographic experiments for this winter.

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!

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.

We finally got some rain after a dry spell and I’m enjoying the flowers on my deck this morning.

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.

Human intelligence measured in the brain – A study that used resting-state MRI analysis on 1000s of people around the world…areas of the brain which are associated with learning and development show high levels of variability (i.e. they change their neural connections with other parts of the brain more frequently, over a matter of minutes of seconds). Further studies using the new technology may rapidly improve our understanding and diagnosis of debilitating human mental disorders such as schizophrenia and depression.

Common Foot Problems (and what to do about them) – Most of my foot problems went away when I stopped wearing high heels!

Postcards provide link to Edwardian social media – A different perspective of the early 20^th century. There is a searchable archive that is available here; I enjoyed doing searches with some family names and locations. The two most common topics that people wrote about were the weather and health!

Amazing spider silk continues to surprise scientists – Phonomic crystals – that’s new vocabulary for me this week. Evidently research on spider silk has shown the potential of new materials (to synthesize) to dampen sound or provide insulation.

Hundreds of years later, teeth tell the story of people who didn't get enough sunshine – Dentin layers formed during a time when a person did not get enough Vitamin D to fully mineralize the structures that form dentin (and bone) provide a window into that aspect of nutritional health long after the person dies…longer lasting that the bones. Dentin layers are also a better indicator because they are not constantly remodeled during life as bones are.

The key to conservation is not what you think – A thoughtful piece about the lack of diversity, equity, and inclusion in the environmental community.

NASA’s Kepler confirms 100+ exoplanets during its K2 mission – Lots of validated exoplanets to pick from for further study by NASA’s upcoming missions: Transiting Exoplanet Survey Satellite and James Webb Space Telescope!

The mystery of why you can’t remember being a baby – A summary of research on the topic….and we still don’t really know the answer.

How the body disposes of red blood cells, recycles iron – It happens in the liver, not in the spleen as previously thought…and requires bone-marrow-derived immune cells as the recycling cells.

Orangutan Imitates Human Speech – 500 vowel-like sounds…more vocal fold control that we previously thought could be exhibited by a non-human ape.

Ancient Brazilians occupied the same homes for centuries – Homes that were never abandoned…just extended with new floors on top of old ones, different types of ceramics and new building techniques.

Photography in the National Parks: Don’t Forget to Pack Your Flash or Reflector for Some Fill Light – This post shows images in bright sunlight with and without flash/reflector….a good ‘lesson’ in improving photos of flowers particularly.

Discover Your World with NOAA: An Activity Book – For kids and educators. The Earth Origami activity was one I looked at. This is quite a treasure trove of activities…all available online.

How to Raise Brilliant Children, According to Science – An interview with the author of Becoming Brilliant: What Science Tells Us About Raising Successful Children. She defines 6 Cs: collaboration, communication, content, critical thinking, creating innovation and confidence spread across 4 levels of development (summarized as seeing is believing, multiple points of view, opinions, and evidence/mastery/intricacies of doubt).

Professor finds positive effects for bringing physical activity to the desk – A positive link between mood, motivation and physical activity without detracting from work or study effectiveness…what’s not to like. For me – the Swopper chair seems to have these effects.

The People vs Coloring Books: The verdict is in – For children…the overall message may be to ‘step away from the coloring book’ and celebrate difference rather than conformity. When I was cleaning out my daughter’s papers from 1^st grade (over 20 years ago) I found a lot of lightly used coloring book type pages; it appears that she didn’t like them very much. She recognized them for what they were – busy work.

Incidence of cancer in patients with large colorectal polyps lower than previously thought – 92% of the colorectal patients referred for operation were noncancerous! My family had this experience and it is interesting to find out that it is not uncommon. Hopefully the more advanced endoscopic techniques can replace the traditional operation in some of these cases.

7 ways to find things to do in nature near you (US Edition) – Good ideas!

Butylparaben can have several endocrine disrupting effects – This is an ingredient (preservative) in many cosmetics and skin care products. Whatever testing was done in the past on the chemical probably did not even check for this kind of issue. And now we have a pervasive chemical that is impacting our biology in a negative way.

Gleanings of the Week Ending July 9, 2016

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.

The Rabies Vaccine Backstory – A little bit of medical history for the week.

Ten simple rules to use statistics effectively – The report is intended for the research community – but it seems like just about everyone needs to understand these. We are bombarded by statistics at every turn…and many times they are coming from outside our area of expertise; we have to make a conscious decision about how ‘real’ what they reveal might be.

Are your pipes made of lead? Here’s a quick way to find out – With Flint, Michigan’s problems with lead in their water supply being in the news, why not do a quick check to see if the pipe bringing water into your house are made of lead?

CDC to Track Algal Blooms – Evidently algal blooms have become enough of a health hazard to warrant this step.

4,200-year-old Egyptian Temple Discovered to have Remarkably Well Preserved Artwork – Images of the same temple from several photographers. One show half the ceiling cleaned…half still covered with soot. I wondered if the soot actually served to protect some of the pigment from being scoured by sand over the years.

Journey Through the Largest Cave in the World – It’s a cave discovered in 2009 in Vietnam. There are sinkholes that allow light into parts of the cave…a jungle inside the cave.

No association between ‘bad cholesterol’ and elderly deaths – Systematic review of studies of over 68,000 people…questions about the benefits of statin drug treatments for them. Older people with high level of a certain type of cholesterol (low-density lipoprotein) actually live as long, and often longer, than their peers with low levels of this same cholesterol. This implies that what is true for cholesterol for young and middle-aged people is not for older people!

A virtual field trip to the Giant’s Causeway, Northern Ireland and Siccar Point, Scotland – Some online geology!

Hubble Images of Jupiter’s “Northern Lights” are Amazing! – Something new to know about Jupiter – it has a much stronger magnetic field than Earth…and Aurora’s along with it.

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!

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.

Gleanings of the Week Ending June 4, 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.

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.

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.

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.
