Gleanings of the Week Ending July 2, 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.

8 Ways to Protect your Eyes if you stare at Screens All Day – You probably have heard of most of these before….but how many do you actually include in your day to day screen time? I just recently got computer glasses…now wish I would have done it years ago.

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.

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 17^th.

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.

Learning Log – January 2016

December was full of learning opportunities - surprising with no Coursera classes!

Udemy. I discovered a new-to-me source of free or inexpensive short courses. The first one was referenced in the Ancient Egypt course I’d completed via Coursera in November. The courses I finished in December were:

Blue: a symposium exploring aspects of life in Ancient Egypt

Napoleon in Egypt

I have already started two more in January:

Unearthing the Trojan War: The Life of Heinrich Schliemann

Photography Masterclass: Your complete Guide to Photography (I got it when it was on sale for $10)

The Udemy courses tend to be chart sets with a lecturer…not as many references or extended reading that usually accompanies the Coursera course. Still – I enjoyed the topics and will explore more of the courses they offer.

Travel to Hawaii. The biggest source of learning experience in December was traveling to Hawaii. I had never been to anyplace like it and the length/complexity of the travel was more too. There were all kinds of tangential topics too – like learning about Dengue Fever (they were having an outbreak while we were there).

Looking forward into January – I am set for more courses because there is not so much going on otherwise. Along with the two Udemy couses, I’m starting one from Coursera as well: Soul Beliefs: Causes and Consequences – Historical Foundations.
