Across the global ocean, billions of small animals undergo a daily commute of hundreds of feet between their daytime habitat in the ocean depths and their nighttime feeding grounds just below the surface of the water. This may not sound impressive compared to the thousands of miles covered during the migrations of whales or birds, but when considered collectively, the migration of these tiny animals blows all other animal migrations out of the water.
An overview of how your cells build molecular clocks to maintain the daily cycles of your life.
At first glance, the animal kingdom has no shortage of tails. From crocodiles to platypuses, squirrels to pigs and fish to boa constrictors, the shapes, sizes and textures are diverse. But whether flat, flexible, paddle-like, scaly, bare, mighty, curly or fluffy, all tails have one thing in common: they are roughly circular in cross-section. Of all the tails in all the world, there’s just one that differs. And it belongs to the seahorse.
Forty years ago, at the birth of gene-editing technology, 140 brilliant scientists from all over the world met at Asilomar to discuss its usage. Now that they could join pieces of DNA in artificial ways, what should they do with it? What are the experiments they need to answer relevant questions? And more importantly, are those experiments safe and responsible? After 3 long days of intense discussion, scientists showed the public that they could self-regulate and set a precedent for scientific regulation.
