Gleanings of the Week Ending December 28, 2013

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.

Short Cycle Efficacy Trials Key to Personalized Learning - How can the myriad of education applications and blended learning models be evaluated?  This article describes some attempts. Hopefully we finally will achieve the focus of efficacy for the individual learner rather than the technology or educational administration.

4 Frighteningly Ambitious Education Experiments for 2014 - There are lots of experiments that I’ve been reading about lately (prompted by some recent Coursera courses). These four caught my attention because they emphasize that many boundaries we one assumed have been softened or even breached by technology. So now - we have some alternatives that have never been available before. All the more reason to figure out how to do ‘short cycle efficacy trials’ (see previous gleaning).

Frogcicle - I’d heard about some frogs being able to survive freezing…this is a video that shows that happening.

A Dingo Ate Australia - The article portrays the dingo, Australia’s only native dog species, from multiple perspectives.

Petrified Life - Time lapse video of the American Southwest…well worth the 5.5 minutes to watch.

The Most Incredible Historical Discoveries of 2013 - It’s the time of year that we get a lot of ‘best of’ lists. It does seem that 2013 had quite a few rather surprising historical discoveries. History is not as well defined as we sometimes assume!

Greenland Ice Stores Liquid Water Year-Round - Water evidently stays liquid in the space around the ice particles in an aquifer that covers 27,000 square miles. A team drilling core samples in southeast Greenland was surprised when they came up with liquid water (from 33 feet in one hole and 82 feet in another). The air temperature at the time was minus 4 degrees Fahrenheit. Another article on the same topic is here.

The 100 essential websites - How many of these do you know about already? I always take a browse through lists like this - and sometimes discover a something worthwhile!

Waiting in the Wings - Mining collections (butterflies, plants and birds) to determine changes over the 19th and 20th century as individual species - and in relationship with other species. Not everything in the food web changes at the same rate.

These are the most beautiful libraries we've ever seen - I am reading more electronically these days but there is still something very appealing about rooms full of books. 

Gleanings of the Week Ending August 31, 2013

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.

Another 'Grand Canyon' Discovered Beneath Greenland's Ice - Right now it is covered by lots of ice….but the data from the increasingly sophisticated instruments monitoring the ice sheet has revealed lots of detail about the topography of what is under the ice. How many of us will live to see this canyon without ice?

Peter Huttenlocher has left the building - An article summarizing the contribution of the child neurologist: synaptic pruning. A simple graph shows it all.

Sonia Pressman Fuentes on Rights of US Women - A summary of the legislation relative to protection of women’s rights over the past 50 or so years. I knew at least vaguely about all of them because I lived through those years - but it was good to see it all in one place and to think about the problems working women still face. The comments are worth looking at too.

Giant solar plane could stay airborne for 5 years, replace some satellites - It would fly above the clouds and weather but still within the atmosphere….And reduce the expense for such things a crop or fire monitoring, providing internet access to remote regions and disaster rapid response.

Changing River Chemistry Affects Eastern US Water Supplies - Rivers are becoming more alkaline….because acid rain causes more rapid leaching of limestone, other carbonate rocks and even sidewalks….and so life in the river is changing. Natural systems have ways to reach a new balance eventual but the path to balance is often very complex.

apple-picking time: our top-pick apple treats - From King Arthur flour. Lots of goodies - at least half look way too high-calorie for my current weight loss diet! But maybe I’ll make one to celebrate when I finally reach my goal (less than 2 pounds to go!)

Thyroid Cancer Biopsy Guidelines Should Be Simplified, Researchers Say - My favorite quote from the article: “…start doing diagnostic tests and procedures more selectively and prudently, as there rare harms to doing unnecessary tests and procedures.” But do we trust doctors to make the best recommendations to us when it is in their financial best interest to do a many diagnostic tests and procedures as possible?

Fantastic Shots of Japan's Summertime Fireworks Festivals - Lots of events in July and August….and these images capture some of the excitement

Brown-bag lunch strategies - Eating well away from home. The strategies in this article are skewed toward the gourmet variety of brown bag lunch - but good to review when get bored with whatever you have been packing. The key is planning (as with most things).

Visualizing the Psychology of Attraction - Infographic
