The Path to ATP
Back in 2014, Eleanor Lutz created “How To Build A Human” which has been shared a lot recently – so I went back to her blog to see what is there and wow!
Here is a new (and helpful) infographic for HL Bio, “The Path to ATP”. Think a simpler version of Gerhad Michel’s famous Roche Biochemical Pathways.
In Our Time: Science (Nature of Science)
If you’re into storytelling and discussion, why not try BBC Radio 4’s “In Our Time: Science” podcast. Good for Nature of Science and TOK connections in IB Biology… and great if you have a commute to kill. Click here for all episodes in alphabetical order.

Space Twins & Epigenetics

The ever-wonderful Genetic Science Learning Center at the University of Utah sent this helpful email update to counter misconceptions around the Kelly Twins’ “Genetic Differences” as a result of Scott’s year on the International Space Station.
You may have seen the headlines about identical twin astronauts, Mark and Scott Kelly, now being “genetically different” after Scott spent a year in space while Mark remained on Earth. Yet much of the popular press has failed to explain that these differences are mostly epigenetic modifications leading to changes in gene expression. Or that several of the analyses were limited to circulating white blood cells and are thus mostly relevant to the immune system.
Here are some great resources they shared:
-
Epigenetics on Learn.Genetics
The Epigenetics module on Learn.Genetics and Teach.Genetics explores how signals from the environment regulate gene expression, including an explanation of how differences in identical twins might arise
- Scott Kelley’s telomeres were elongated in space and shortened on Earth. Learn all about telomeres from this primer.
- The study also compared the microbiomes of the Kelly twins—which, it turns out, were quite different even before Scott Kelley traveled to space. Explore the Human Microbiome module on Learn.Genetics and Teach.Genetics.

They have great resources for students at the Genetic Science Learning Center, and for educators at their new Teach.Genetics site. You can also follow them for Twitter updates here. Sign up for the Teach.Genetics mailing list from GSLC here.
Crash Course: Statistics
Crash Course are at it again, this time with a new statistics course. This introduction might be interesting as you think about your IA’s. How do we understand what are data are telling us… and how do we design tests that will give us data that we can actually use?
8 Mind-Blowing Optical Illusions
Here’s nine neat minutes from Sci Show on illusions – classic and modern – that will be of use to those studying Option A: Neurobiology & Behaviour.
Before the Flood: The Science is Clear, the Future is Not.
New from Leonardo DiCaprio and National Geographic, Before the Flood is a compelling and powerful climate change documentary. Where are we in the world right now with our understanding, challenges and potential solutions. What actions need to be taken right away?
The full movie is was available initially for free on YouTube, and their action website hosts more resources for use in class or discussions. Click here for other platforms where you can view, rent or buy the movie.
PaperPile: Managing Citations in GoogleDocs
I have been looking for something that can replace MS Word’s citation manager and work in a similar way to Zotero. Here’s a quick post on how to use the PaperPile add-on for managing references in GoogleDocs. Paperpile is free from the Chrome store, though I am using the upgraded version.
