Lessons from Lizards

Lizards can lose their tails. The idea is that reptile-guzzling predators are distracted by the abandoned appendage while the lizard scarpers to safety. And then the lizard’s tail grows back. This ability to regenerate body parts has long interested scientists, who hope to mimic it in humans. As the most closely related animals to humans (who sometimes regrow lost fingertips) that can regenerate entire body parts we and lizards share the same toolbox of genes for the job. Researchers have now carried out the first genome analysis of tail regeneration in the green anole (pictured), which revealed that during tail regrowth lizards turn on 326 genes, including those involved in embryonic development, response to hormone signals and wound healing. By following the lizard’s genetic recipe for regeneration, then harnessing those genes in humans, it may be possible to regrow new cartilage, muscle or spinal cord in the future.

I don’t even know what to say.

Well, the girl you like likes you back, so I’d be pretty excited if I were you.

That’s what I mean. This is amazing! But what do I do now? I’ve been ignoring her for weeks now.

If I were in your position I know exactly what you’d tell me to do.

And what’s that?

Talk to her! Apologize! Let her know how you feel. You can’t keep avoiding her forever.

Hahaha, that is what I’d say, isn’t it? You’re right. I need to talk to her.

Hey, Marilyn’s going to go get a new tattoo in a few days. Why don’t you go with her and take her somewhere special afterwards so you can talk? 

That would be perfect. Thank you, Lacey. If you hadn’t talked to me about this I don’t know what I would have done.

Ha, I don’t even want to think about what would have happened. And don’t worry about. Oh, and while I’ve got you sitting here, I have some news.

Researchers find continuous lineage of North American Arctic settlers over 4000 years across diverse cultures

Archaeologists mapping ancient cultures in the North American Arctic—a region spanning present-day Greenland—have long puzzled over how different cultures relate to one another. Now, an unprecedented large-scale genomics study has traced many such cultures to the Paleo-Eskimos, a people who early inhabited the harsh environment continuously for 4000 years, only to vanish mysteriously about 700 years ago. The discovery could change how scientists understand migration patterns in the North American Arctic.
