A Ranking of the Deadliest Animals in the World - The mosquito is the only one more deadly than humans!

Rainbow Slime Recipe for Play - I couldn’t resist…it’s pretty and fun looking…a great activity for the child in us all!

Two items about bees: 5 Facts about Bumblebees—and how to help them (the bumblebees were very active on a redbud blooming in our area) and The Waggle Dance of the Honeybee (this is not a new video…but timely as the bees become more active this year).

10 Spring Cleaning To Dos for Your Digital Abode: Part I - This is a list written for teachers but it makes sense for others as well! Part I is the first 5 of the 10.

Some of the Strangest and Most Artistic Rooftops in the World - The ones that are green with vegetation are my favorites.

Exquisite Macro Photos Reveal the Miniature World of Insects - My favorite is the dragonfly catching a ride on the seed puff.

Mount Baldy at Indiana Dunes National Lakeshore to Remain Off-Limits Indefinitely - Sand behaving in unexplained way….the world is not always easily understood.

Ethereal Silk Scarves Feature NASA's Photographs of Space - I want one of these for Christmas!

Elegant Animal Illustrations Created Using a Morié Pattern - The owl captured my attention…..and then the bats.

Optimizing sweet potato production - Sweet potatoes are one of my favorite foods. I’m glad they are becoming more appreciated. I’ve always had good luck growing them 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.

Bridging Two Worlds - Lynne Quarmby is a cell biologist….that paints. See some of her art work here.

Several interesting paper sculpture posts: From Zim and Zou (my favorite is the bird in the first image), Massive Paper Installation Feels like You’re Walking Inside a 3D Painting and Bird Sculptures

Wish you could fertilize crops with pee? Urine luck - Article from Grist. It caused me to wonder about 1) how sustainable thinking looks for solutions that are better for the planet….but may be less expensive too, 2) how often sustainable also means ‘closed loop’ (i.e. there are no bad bi-products that build up as ‘waste’) and 3) infrastructure changes that will enable sustainability (in this case -bathrooms and sewer systems could be enablers, but different than they are today).

Noninvasive colorectal cancer screening tool shows unprecedented detection rates - Hooray! It would be great if this or some other non-invasive test became the diagnostic of choice rather than colonoscopy! No one likes the colonoscopy or the prep it requires. Surely the non-invasive test will be less expensive too.

Loblolly pine genome is largest ever sequenced: Seven times bigger than the human genome - This article includes a good explanation of the computational challenges of genomics.

Enormous Climbable Structure - Intriguing design. The sight for the developer is here. There are quite a few of them installed in children’s museums in the US and they all look like lots of fun.

Helpful Infographic Illustrates Polite Dining Around the World - Learn about the cultural nuances of dining in other countries.

Americans using more energy - Not a good trend….Are we using more as the economy improves?

Fair bosses pay the price of burnout - Procedural fairness (structured and rule bound) is beneficial to the organization and employees….but it is hard to sustain without feeling the strain. Should leadership/management training be updated to at least acknowledge that strain and suggest ways to cope with it? Maybe sabbaticals (The Working Vacation) should become more common in non-university organizations.

Daylight saving impacts timing of heart attacks - Should people with heart conditions ‘spring forward’ more gradually?

Gleanings of the Week Ending March 29, 2014

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.

The Garbage Man - Thinking beyond the recycle bin…closed loop recycling.

25+ Digital Wildlife and Nature Maps - Lots of perspectives. I particularly like the Journey North (under Migration and Tracker Maps) because of the time of year….check out robins and monarchs migration.

The 7 Rules of the New Food Revolution - Common sense from Prevention magazine….with links to more information about each one.

Things you should be able to do in your local library - Many communities have library infrastructure originally developed for print media. As more moves toward digital formats - there is opportunity for the library to evolve into something quite different to make the most of the location, building, and engagement capacity. Some of the things on Richard Watson’s list are already part of my library....and others may become the next wave of enhancements.

Google cameras take rafting trip at Grand Canyon - If you can’t make the raft trip through the Grand Canyon physically, take a virtual trip! The Google Colorado River Site is here (there is an ‘Explore the Colorado River’ video toward the bottom of the page that is a short intro to what is available on the site).

What are anonymous companies? An infographic - From TED. “My wish is for us to know who owns and controls companies, so that they can no longer be used anonymously against the public good.” - Charmian Gooch, 2014 TED Prize Winner

Married and working together to solve inequality - Except from an interview with Bill and Melinda Gates

How the Container Store Uses Wearable Tech to Think Outside the Box - Replacing walkie-talkie technology with smaller wearable devices with more functionality.

The $1 Origami Microscope - What a great idea! One of the STEM Fair participants from a few weeks ago lamented that she did not have a microscope easily available for her project. I hope this kind of minimalist design (and low cost) can make microscopes very common around the world - for students (and that virtually everyone is a ‘student’ in some aspect of their life).

Gorgeous Papercut Light Boxes - From two Denver based artists. 

Ten Days of Little Celebrations - March 2014

Over a year ago I posted about finding something to celebrate each day. It’s an easy thing for me to do and the habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations;’ here are my top 10 for March 2014.

STEM Fair - These spring events used to be called ‘Science Fair’ but the fair has enlarged to include Science - Technology - Engineering - and Math so they have changed the name. I have volunteered as a judge for our county fair for the past 10 years or so. It seems like every year is an improvement over previous years and this year there was a bigger improvement than usual! This year the middle school students were much more articulate about the statistics they were using (standard deviation in particular).

Great snowflake pictures - Some years we get snow in March and sometimes we don’t. This year not only did we get a good snow, the situation was ideal of snowflake photography. Of course, I celebrated with snow ice cream!

Raisins soaked in apricot brandy - I plumped some dried out raisins with apricot brandy for an apple - raisin - celery salad. Yummy! I may do this every time I make the salad from now on. Little culinary successes are always worth celebrating.

Volunteer naturalist classes - Last fall had did most of my prep for becoming a volunteer naturalist by shadowing people that had done it before; this spring I am taking the classes and enjoying them tremendously. I even won the drawing for the book give away - Bringing Nature Home by Douglas W. Tallamy. Wahoo!

Philadelphia buildings - I had a hard time choosing between the Philadelphia Flower Show itself and discovering the interesting buildings of downtown Philadelphia which will probably be the focus for my next foray into the city. Either way - the March day trip to Philadelphia was a daylong celebration.

The last two volcano lectures - I worked my way through a series of online lectures on material science related to volcanoes that stretched my memory of chemistry (from classes about 40 years ago) and was thrilled to get to the last two lectures that focused on how lab work is done with silicate glass and how all the research and field work gets translated onto geologic maps.

A clean car - With all the snow, my car became thoroughly encrusted with salt. Its shiny clean look coming out of the car wash was worth celebrating.

Lots of feathers - It was a little disconcerting to find a pile of feathers beside our house but then I realized that the presence of a predator was an indicator of a working ecosystem in our neighborhood….and  I enjoyed having the feathers for a photography project.

Pot luck lunch - I have always liked pot luck events. Sometimes there is a skew to desserts but this one had great variety. If anything, it was skewed toward fancy salads.

Work experiences to pass along - One day I was able to pass along two potential solutions to my daughter from my career: 1) Hotel too expensive for a conference? Room with someone. 2) Logo shirt required for an outreach event way too big to tuck into slacks? Wear it tucked into a skirt or belted like a short dress over leggings or skinny slacks. It’s worth celebrating any time lessons learned long ago are still relevant!

 

Microscope Project: Onion Skin Abstracts

I was preparing lunch yesterday - cutting up a red onion - when I realized that thin pieces of onion would be good subjects for the microscope. My goal was to do something artsy rather than scientific. See the results in the slide show below.

The outmost layer was very dry and stiff but I put a small piece on a slide. It looked like a brilliant pink stone wall under the microscope.

The next layer of the onion was more flexible but still not quite soft enough to be edible. I cut some small pieces. They looked various shades of deep purple, reddish and then clear. They dried out a bit before I got them under the microscope and I discovered that the bubbles made them just as interesting as the cell structures.

When I was dicing the onion - one of the major layers fell away and a think membrane - without color - was visible. I put several pieces of it on slides and tried some dyes/food coloring to get the green, yellow, orange, and purple images.

Rainy Day Mending

Most of my mending is for clothes but yesterday I polished off two non-clothes mending jobs that had accumulated. The jobs were particularly satisfying because they took very little time and prolonged the useful life of the items.  

The last time we laundered a comforter used in the guest room - a side seam had come open and the stuffing was hanging out. Having recently discovered that this particular comforter was just the right size and thickness to make the sofabed comfortable for an adult, I decided it was worth mending.

I sat in a rocking chair beside a window looking out on the gray, rainy day…with the mound of comforter positioned so that I could pin the seam closed and stitch it up. When I got started, I realized that the fabric of the 15 year old comforter was not in the best shape…..but the mending will probably get it through a few more washings. Mending was faster than buying a new comforter (and cost less too).

Another mending job for the day was to re-stitch the hotpad I had put around a handle of the laundry basket after the grip had broken. The original work had been done about 10 years ago and the knot of the hand sewn edge had unwound. The pad had extended the life of the basket since otherwise the sharp edge of the plastic made it very uncomfortable to carry. Now - the laundry basket handle padding is good for many more years after the re-stitching today.
