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)!

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.

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.

19 Different Foods that Surprisingly Bloom Beautiful Flowers – Great visuals and informative too. Think of all the different kinds of pollinators needed for these flowers too.

Fulfilling Water Needs as Big as Texas – The Nature Conservancy has created the Texas Water Explorer – wish Maryland had a similar app although I did find Water Quality Assessment Maps for Maryland which have much of the same information. I liked the picture of the Pedernales – brought back memories of a vacation in the state park along the river almost 40 years ago.

New knowledge for managing tree-killing bark beetles – After learning more about the southern pine bark beetle when I visited Chincoteague, I’ve been more aware of the damage it is causing…noticing articles like this one. There is really no good news.

Monet-esque Micrograph and Bug Brothers and Subterranean settlers and Zika viron and Cretaceous Chameleon – The Scientist almost always includes an image in its newsletters. Here’s a collection from March.

Blood test can predict risk of developing tuberculosis – It would be good if a blood test could do this. I remember having to get chest x-rays for my job since I responded to the TB skin test (i.e. was a latently infected person) …and repeated chest x-rays are not a good thing.

It has fast become antiquated to say that you ‘go online’ – Living constantly online…it’s becoming the norm for more and more people. And even when we turn off our devices, our online world continues while we are away. It is the new normal.

Developing better drugs for asthma, high blood pressure – The point of the project is to avoid complications from drugs that require treatment – separate from the original reason the person was taking the drug in the first place. It’s a good goal but I prefer the research toward interventions that address the root cause of a problem rather than starting with a drug that works most of the time and trying to avoid complications from it – which seems to be the goal of this research.

Sleep: The A B Zzzzs and  Learning with the Lights Out and Desperately Seeking Shut Eye and Under the Cover of Darkness (infographic) and Who Sleeps? And Characterizing Sleep (infographic) – The Scientist has had a number of interesting articles about sleep. I wonder how often a person’s sleep (or lack of sleep) is the primary cause of a health issue….and how often doctors decide to treat a sleep problem unless is overwhelming obvious that sleep is the problem. Some sleep problems may be very difficult to treat and may require a significant change in lifestyle which is often very difficult.

These Ancient Trees Have Stories to Tell – I like trees…and these are artfully photographed. They were printed in black and white; I think I like trees in color more.

The Artificially Intelligent Doctor Will Hear You Now – I like the idea here – particularly that it takes into account the patient’s history and circumstances…not just symptoms. One of the things I have observed is that doctors typically key off one or two recent test results rather than taking the patient’s full history into account. They have the problem – like all of us – of being overwhelmed by data. Having an AI that would take all of that into account would benefit the doctor by saving a lot of patient history review time and the patient would get a more informed diagnosis and treatment.

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.

Dragonfly is world-record flier – Confirmed by genetic analysis…this insect makes transoceanic flights.

Identity unearthed: How excavations in Sudan reveal the transformation Egyptian, Nubian culture – Cultural blending in the ancient world…with a lot of individual choice involved: Nubian bed or Egyptian coffin, wrapped like a mummy or not, Egyptian-type amulet or Nubian jewelry (or both).

Fitting into what I’m learning in my Big History class: Mysterious cosmic radio bursts found to repeat, Hubble breaks cosmic distant record: sees universe soon after big bang, and Einstein’s gravitational waves ‘seen’ from black holes – Every time I take a course, it seems like there are a lot of relevant articles coming out in the news feeds!

Astrobiology: Understanding Life in the Universe – Student companion site for the Charles S. Cockell text. Includes chart sets for each chapter – if all you want is an overview of the topic. The book is developed to support the Coursera Astrobiology course taught by the author (which I took last year).

Migrating Monarch Number Rebound – Hurray! The good news is from analysis of the numbers of butterflies at hibernation sites in Central Mexico. There were 3x more butterflies than the year before. Still – the area is still a lot lower than the 45 acres in 1996. The area was 10 acres in 2015, 2.79 in 2014, 1.66 in 2013. Outside of the hibernation sites – more people are planting or conserving milkweed which is needed for monarch survival and keeping that focus on increasing milkweed availability in the environment is what we in the US can do to help.

Toward diagnosing diseases such as cancer in their earliest stages – But can it be done very inexpensively? So far a lot of these diagnostic tests have added cost to the medical system and there a lot of people that are not going to have the disease (i.e. there is a lot of cost of lots of testing to find the few people that need treatment).

Can some birds be just as smart as apes? – Research with corvids (crows, jays and their kind) and parrots reveals that they are capable of thinking logically, of recognizing themselves in the mirror and of empathy. Even though the brain structures and size appear quite different…both birds and apes have a prefrontal brain structure that controls similar executive structures.

Irish Eyes Soda Bread – Something to bake for St. Patrick’s day – coming up on the 17th.

Uncovering the Roman Roads Cutting Across England - An amateur archeologist using LIDAR…reveals roads the Roman’s build for trade and rapid deployment of troops (follow the ‘full story’ link at the bottom of the article to see a map).

Who Sleeps? – Sleep conserves energy and may be why so many species sleep…but there may be other benefits at all. This an article that summarizes our current understanding of sleep in some major types of organisms (marine mammals, birds, insects, and mentions ongoing research.

Getting Home from Hawaii - An Adventure

/

It was always going to be a long flight from Hawaii back home to Maryland. Our plan was to begin in the evening and try to sleep through as much of it as possible.

But the plan fell apart almost immediately. Our fight from Kona was delayed from 10:15 PM on a Sunday to Monday at 6:30 AM. We stood in a long slow line to get out larger bags checked and a voucher for a hotel room and transportation to/from the airportt – even though it would only be for a few hours. The Kona airport is open air and the wooden benches in the waiting areas have unmovable armrests (i.e. very few places to actually lay down and try to sleep in the damp and cool night). The Royal Kona Resort voucher gave us the ability to shower and change clothes which helped us feel a little better; we only got about90 minutes of sleep!

When we got back to the airport early the next morning, we discovered that the art glass we had purchased (nicely wrapped in bubble wrap in my husband’s carry on) had to be hand inspected by TSA. It was good that there was not much of a line. They managed to preserve most of the bubble wrap and re-taped the package. As we got to the waiting area, we discovered that about half the passengers from our flight had spent the night in the airport; evidently there was some confusion by the airline personnel re vouchers. Aargh! I felt very sorry for the rumpled and sleep deprived people.

The airline brought in donuts and granola bars for breakfast….and then we waited for the plane to be ready to board. We got off later than planned so that everyone missed their connecting flights in Los Angeles – including us. That made the second time the planned trek home had to be modified. The airline had rescheduled us onto another airline’s flight into Dulles – and our car was in the parking garage at BWI. After a little haggling – we were provided a voucher for transportation from Dulles to BWI. We had time for a regular meal in the Los Angeles Airport before catching our cross-country flight.

The biggest miracle of the trek home: our luggage that had originally been checked to go to BWI arrived at Dulles with us in the wee hours of Tuesday morning. By that point our biological clocks were totally confused having gotten no solid sleep for over 40 hours. We got home and slept a few hours then go up to ratchet ourselves back toward Eastern Standard Time. It took us several days to recover!
