Fraser Cain824,747Super Science Circle for October, 2013I know it's been a while, so it's time for a new Super Science Circle - the October 2013 edition.In case you weren't aware, the Super Science Circle is a list of more than 400 people who are actively engaged on Google+ and regularly post about science and education. We've got journalists, scientists, even a few astronauts. The Super Science Circle should be your best response to anyone who tells you that Google+ is just a ghost town. If you love science, this circle will deliver the goods.If you know anyone who actively posts about science, please let me know and I'll add them to the list.2013-10-04 20:14:53415304682

Fraser Cain798,034Super Science Circle, July 2013 EditionNeed more science in your streams? Want to convince a friend that Google+ is a thriving place of science and rational thinking? Then import my Super Science Circle and be amazed at the awesomeness.PLEASE RESHARE THIS CIRCLE... FOR SCIENCE!Every single person in this circle is active on Google+ and regularly contributes high quality posts about science. You've got my personal guarantee.As always, I recommend you import this group into a temporary circle and look for people who match your interests. Then pull them over into more permanent locations in your circles. Or just wait for me to give you an update next month.If you want to be included in this circle, just make a post in the comments and I'll check out your profile.I'm looking for people who:1. Are active on Google+ (but not too active)2. Regularly post about science3. Provide context and additional information, and not just bare links or annoying memes.2013-07-16 18:35:56415255987

Markos Giannopoulos3,766197 interesting People // If you're into technology, the Web, photography and science, here's a circle to consider. Methodology: out of 3200 people that I follow, using +Circloscope I ordered them according to relevance score (calculated by Google depending on whose posts I engage the most) and filtered for a value over 30, then filtered for whether they are active (when was their last post) and finally filtered by whether they were in my "must read" circles. Voila! I hope you find it interesting :) #circleshare   #sharedcircles   #sharedpubliccircles  #circlesharing  2013-05-26 09:51:2119713412
Fraser Cain779,548Super Science Circle - May 2013 EditionNeed more science in your Google+? Well, here's all the science you can handle! Enjoy my latest, heavily curated edition of the Super Science Circle.Please share this circle... for Science!For the uninitiated, I maintain a circle of 450+ people who are active on Google+ and regularly post on Google+. In this circle you'll find scientists, journalists, astronauts, educators, and science enthusiasts. By importing this circle into your own circles, you'll immediately gain a vibrant and fascinating feed of amazing science stories.I recognize that it might be too much science, so I suggest you create a brand new temporary circle and evaluate the people in the circle. Only transfer the keepers to your permanent circles. Then, when I update the circle next month, rinse and repeat.Are you active on G+ and regularly post about science? +mention me and I'll check out your profile.Remember, please share this post2013-05-22 19:26:51456348088
Fraser Cain770,050Super Science Circle - April 2013 EditionIt's time for another sharing of my Super Science Circle. This is a collection of 400+ active people on Google+ who often post about science. If anyone tells you G+ is a ghost town (not that anyone does any more), get them to import this circle. PLEASE SHARE THIS CIRCLE... FOR SCIENCE!I have personally reviewed each and every person on this list, to make sure that they:1. Are active and engaged on Google+2. Regularly post science-related stories on Google+In this list you'll find scientists, journalists, researchers, professors, astronauts and general science enthusiasts. Not everyone in this list is going to be to your personal liking. So what you'll want to do is import the list into a temporary circle. Then move people over one by one into more permanent locations in your circles.I'm always looking for more people to add to the list, so if you know people who meet my criteria, feel free to nominate them.Again, please share the circle.

Fraser Cain759,117The Return of the Super Science CircleOkay, I'll admit, I made a mistake in retiring the Super Science Circle. I wasn't wrong; Communities are still the future and the best way to make friends here on Google+. But I realized that the Super Science Circle is simple and efficient way to get new people to see that Google+ isn't a ghost town.PLEASE SHARE THIS POST... FOR SCIENCE!When I was attending +ScienceOnline 2013, I must have helped dozens of people join Google+, and the first thing I had them do was import this circle. It's an invaluable tool for getting new people up to speed.So, I just did a complete refresh on the circle. I examined every single member and judged them according to my two-part criteria:1. Active in the last 30 days or so.2. Regularly post on scientific topics.If you know anyone who might make a good candidate for this circle, please let me know.As always, import this circle into a new, temporary circle, and then you can refresh it when I share a new version.DON'T FORGET TO SHARE THIS POST2013-03-19 22:39:3139967159161

Fraser Cain694,882The Final Super Science CircleWell, this is it, this is going to be the last posting of the Super Science Circle. Why? Communities, that's why. In case you didn't know, I've been maintaining my Super Science Circle from the very beginning of Google+. As soon as the feature to share circles was enabled, I was happy to share those circles around into Google. I did this because it was very difficult for people with related interests (science) to be able to find each other. I wanted new G+ users to realize this place isn't a ghost town; there are vibrant groups of people actively discussing scientific topics.But it was a hack. Each month took me almost an entire day to curate down the list of people, remove the inactive, and incorporate newly active people who often posted about science. And it was always imperfect. Some people got a massive boost in followers and engagement, while other, equally deserving people were left out.It was inelegant, inefficient and arbitrary.But now you can do this all on your own. You can go into any Community that matches your interest and instantly discover thousands of people who share your enthusiasm for a topic - just joining a Community will bring a trickle of posts about topics that interest you back into your stream. Keep your participation in the Community, or circle the most interesting people and harvest them back into your own stream.In the coming months, I'll be suggesting Communities you should join, instead of people you should circle. Thanks to everyone for using the shared circles and helping science get such a firm foothold here on Google+. Thanks to all the past and present members of the Super Science Circle for sharing such wonderful stuff.Science!2013-01-17 02:59:31420544084
Shells Bells5,180Best of 2012 CircleThis circle is some of the G+ awesomeness that has enriched my life this year - and I am grateful.  A while back +Sean Cowen asked what G+ has meant to us.  After watching Brene Brown's TEDTalks (http://www.ted.com/speakers/brene_brown.html) I realize that for me, G+ has been a lesson in vulnerability and courage. I have been humbled by the courage of every one of you.  I love that women post no make-up pictures and that you all speak your minds (your clever, creative, crazy & beautiful minds...). I have been blown away by the public sharing regarding topics as deep as abuse and depression - talk about vulnerability and putting yourself out there - absolutely amazing.  By doing so, you have helped others in ways you may never know.  <3Inspiration's what you are to me, inspiration, look... see.  Led Zeppelin - Thank YouYou have inspired me. (warning TL:DR personal stuff below) Oh, & I did include some new peeps.  If they're freaks, blame +Ben Zaitz.This month, I gathered some courage and let three people see me in, what was to me, a position of vulnerability.The first was a very dear friend from Elementary School.  For the past few years, I avoided HIRLing because I was ashamed of my weight and I guess I didn't want to disappoint him.  The same reason recently kept me from seeing a dear High School friend.  I saw them and each did not care that I was not perfect, they love me for me.  Mann, it was great to see their faces again, talk in person and have some non-virtual hugs.  <3I attribute this change in thinking to your responses to a July post: https://plus.google.com/115807723984369772514/posts/Ui2TQBPuELKAmong the other awesome words from you peeps, +Alvin Stearns wrote, "Never again compare yourself to others so that you make unfair and useless judgments about yourself or others.  That includes comparing yourself to you in the past."  The third was that, with your encouragement on a private post, I actually asked a guy out.  I would have never even considered doing that a year ago.  (He has a gf, so no deal, but it's all good cause he was cool.)I know these are little things, but I thank you all from the bottom of my heart.  And thank you to +matthew rappaport, Bobbi Jo Woods and +Tiffany Henry for coordinating the first NYCHIRL. Due to my kiddies, I couldn't see +Daria Musk and +Ryan Van Sickle2012-12-31 06:09:4450026231

Peter Smalley10,068#sharedpubliccircles   #science  It's been a while since I shared a circle. Let's fix that, shall we? Here is my Circle of Science. Here you will find people who are practicing scientists, science writers, and science enthusiasts - and sometimes all three at once. There are biologists, chemists, physicists, microbiologists, food safety scientists, mathematicians, neurologists, astronomers and many other disciplines represented here. But regardless of their specialties they are intelligent, interested, and interesting.I won't call this a curated circle per se, but I can personally speak to quality of many of these individuals. Many of them are true gems.FOR SCIENCE!2012-11-26 17:29:545015211
Paul Christen41To the person that originally shared this circle with me (I forgot who...)Thank you.I am getting really tired of the glorification of stupid and the vilification of intelligence. I am afraid that its a systemic problem and frankly, I see no end in sight. Its similar to American politics in many ways."Well sure, professional athletes shouldn't rape women, but the dood can throw a football!" "Well, yeah, he ran a dog fighting ring, but let him play football and be a role model to  children anyway."We had a President, that was re-elected, that on any scale was a buffoon at best.The list goes on, and lets not forget the other side  of the  proverbial  coin, how often have we heard politicians talk about the "elite smart people"?Watch an episode or two of "Big Bang Theory". REALLY funny show, I refuse to watch it. I saw two episodes and both portrayed intelligence as negative.I heard an adult say (and I shit you not) "Kids don't need to learn what the mathematical median is, its useless knowledge, average is good enough." I tried to explain how it differs from average and how knowing the average and the median can help get a better view of the data (no point in going too deep) and got "nope, not needed".Whatever, I'm ranting and off the rails here.Do what you need to do to keep YOUR intelligence up and those around you, for the love  of Xenu, fight the good fight. Following this  circle  might help.2012-11-07 13:15:584135110

STEM Women on G+2,184STEM Women on G+ Shared Circle (Release 3)This is the first crowd-sourced, collaboratively curated circle of Women who work in STEM (Science, Technology, Engineering and Math) fields that are also active on G+.We had some simple criteria for inclusion in this circle; every woman in this circle has a job that relates directly to STEM or is an advanced student of STEM. They are all active users of G+ and post Publicly about their STEM discipline regularly (i.e. at least once a week).• Import these people into a brand new circle, and then move people over into your permanent circles if you like what they post.• Reshare this post, to get the STEM goodness out to as many as people as possible :)• If we have missed someone that should be included in this circle in time for our next update, please nominate them at http://goo.gl/rvKEf. We will be actively curating this circle once a month or so, removing inactive users, adding new active users, so consider this a work in progress :)• Please also make sure that the nominee has added the STEM Women on G+ Brand Page to their circles (we cannot include the nominee in this shared circle unless she does that).--------------------------------------------------------------------------------------This circle is curated by +Buddhini Samarasinghe, +Rajini Rao, +Christine Paluch, +Liz ℚuilty and +Liz Krane. A HUGE thank you to everyone who supported this crowd-sourced effort by sharing the original post and by nominating people for it - this wouldn't have been possible without you! #STEM #stemeducation #science #technology #engineering #maths #sharedcircleday #SharedCircles  2012-08-17 05:03:27167110233

My Personal Dialect Map: http://nyti.ms/1zO9pNm

I talk like I'm in the San Joaquin Valley (which is neither where I live nor where I was raised).
I've changed answers over time, e.g. I called soft drinks "coke" as a kid, but "soda" now.
The small freshwater lobster-thing one pins me right where I grew up, which makes sense given that's where Mom taught me to look for them under rocks.
I once got in an argument with my SIL's 's ex-MIL over mary/marry/merry.
I have still never seen a map showing a pattern for long vs short A in "apricot," but would love to. (Which do you use and where are you from?)

My kid just watched Annedroids, and is currently on the floor trying to use a combination of dishes, duplo and playmobil figures, and a battered toy towtruck to create an "android cherry picker truck."

He's rocking back and forth, one knee bouncing, clearly needs to pee desperately. "Take a break and go pee."
"I don't need to pee."

"Put it on pause and go pee."
"/sigh/ This isn't a video, I'm actually inventing."

"I'll bet Anne and other real inventors go pee as soon as they realize they need to."

Then I realized: Who am I fooling? Of course they don't. They sit at their projects and wiggle until their eyes turn yellow.

What Can We Learn from the Italian Earthquake Trial?

"When a court convicted earthquake scientists of manslaughter, seismologists everywhere feared the worst for their own efforts at informing the public. After the convictions were overturned on appeal this week, experts, journalists and the general public can consider the wider lessons learned."

My kid had a bad cold, then 12 hours later his other mama came down with a cold, then 12 hours later I came down with a cold. It seems to be a 36ish-hour cold, or was for the other two. My recovery is decidedly lagging. But the other parents work for a salary and I get to stay home with the kid (my choice and joy) and don't get PTO, so today we're watching a lot of videos and I'm on half-speed.

What a tidy mowing job.

Egmont National Park, New Zealand | Korea's Kompsat-2 Satellite
Egmont National Park on New Zealand’s North Island is pictured in this satellite image. National parks protect forested areas from human activities that cause land degradation and deforestation. The boundary between protected and non-protected areas is often very clear in satellite images—as we see here between the green, densely forested area and surrounding agricultural landscape.

The land here was first formally protected in 1881, within a 9.6 km radius of the mountain summit. With high rainfall and a mild coastal climate, the park is home to a lush rainforest, with some plants unique to the park. Halfway up the mountain slopes, the forest is sometimes called the ‘Goblin Forest’ for its gnarled trees and thick moss.

The mountain at the center of the national park has two names: Mount Egmont and Mount Taranaki. Taranaki is the original name given by the indigenous Māori people, while the name Egmont was given by British explorer James Cook after John Perceval, 2nd Earl of Egmont in 1770. Many places in New Zealand have official dual names or, as in this case, alternate names in the original Māori and English (following colonisation by the British).

The mountain is considered an active volcano, although it has been dormant for over 150 years.

According to Māori mythology, Taranaki used to reside over 100 km farther east near other large volcanoes when a fight broke out over the female Mount Pihanga. Taranaki lost and fled west, carving the gorges of the Whanganui River along the way before stopping. When the mountain peak is covered by clouds and mist, it is believed that Taranaki is weeping for Pihanga.

This image, also featured on the Earth from Space video program, was acquired on March 6, 2013 by Korea’s Kompsat-2 satellite.

Your cells contain mitochondria, little factories that help convert food into useful chemical energy, using oxygen.   These guys were once bacteria in their own right!   About 1.5 billion years ago they joined forces with cells that couldn't handle oxygen.  Now you need them and they need you.

But they still have their own DNA, separate from the rest of the DNA in your cells.  Mitochondria are passed down only from mother to child, via the egg cell.  So, your mitochondrial DNA gives information about you, your mother, your grandmother, and so on.

Why does mitochondrial DNA come only from the mother?  For starters, an egg cell contains 100,000 to 1,000,000 molecules of mitochondrial DNA, while a sperm has only 100 to 1000.   On top of that, most mitochondria in a sperm cell stay in the tail, and sometimes the tail is lost during fertilization.  But on top of that, in mammals it seems the egg actively destroys any mitochondria that happen to get in from the sperm.

Puzzle 1: Why?

But in biology everything is complicated.  Biologists argue about how likely it is for people to inherit mitochondrial DNA from their father.   In a test of 172 sheep, three were found to inherit mitochondrial DNA from their father!   But in humans, there is so far just one recorded case of it happening.

Your mitochondrial DNA has just 37 genes.  It's made of about 16,600 base pairs: molecules called A, T, C and G, just like your ordinary DNA.  The information gets copied to RNA when the genes are used to make proteins, and the T gets copied to U, while the rest stay the same.

This chart shows the mitochondrion's genetic code.  More precisely: each codon, or triple of base pairs U, G, A, and C, is translated into an amino acid. Amino acids, the building blocks of proteins, have fun names like phenylalanine, leucine, isoleucine and so on - but in this chart they're abbreviated to Phe, Leu, Ile, etc.

The mitochondrial genetic code is a bit different than the genetic code used elsewhere in your cells!  The differences are marked in red:

• AUA codes for Met instead of Ile as it does elsewhere. 

• UGA codes for Trp rather than being a stop codon (meaning, a codon that says the protein is done).

• AGA and AGG are stop codons instead of coding for Arg.

The same code is used for mitochondria in all vertebrates, as far as I know.   Some invertebrates have slightly different mitochondrial genetic codes.

Puzzle 2: Why is the mitochondrial genetic code different in the above ways? 

This is an extremely hard puzzle, and I doubt anyone knows the answer for sure, since it could simply be due to random events that happened billions of years ago.  But I bet people have thought about it, and I'd love to know any good ideas they've had.

Here's a clue: when the mitochondrial genetic code differs from the 'usual' one, it tends to be simpler!   All the mitochondrial genetic code consists of blocks of 2 or 4 codons that do the same thing.  Most of the usual code is this way - but AUA and UGA break that rule.

California also has an overwintering population. The eucalypts on a historical farm three miles away have monarchs in December, though perhaps fewer recently thanks to this fierce drought.

If you want to plant milkweed -- and please do -- it's a good idea to find the species most native to where you live, though anything is better than nothing, and plant it where ever it will grow. I've been tempted to make seed bombs to toss along the edges of sound walls, vacant lots, etc, as long as it's not a place likely to be sprayed with chemicals or mowed.

Comet A1 Siding Spring vs Mars: Views in Space and Time

Oh, to be a stranded astronaut on the surface of the planet Mars this week.  There’s a great scene from Andy Weir’s recent novel The Martian where chief protagonist Mark Watney uses the swift moving moons of Phobos and Deimos to roughly gauge his direction while travelling across the expansive Martian desert.

This week, the skies over Mars will also be graced by an unforgettable and spectacular sight: the extremely close passage of Comet C/2013 A1 Siding Spring.
