Defrosted Moss Sprouts Anew After 1,500 years in Antarctic Permafrost


Last year I blogged about the surprising discovery that mosses released after 400 years of frozen glacial ensquashment had managed to survive and sprout new growth, a finding that radically altered our ideas about regrowth during the retreat of ice ages. Now, a new study in Current Biology pushes that back at least a millennium [...]

How the Mosses That Got Run Over By a Glacier Survived Their Ordeal


A few months ago, scientists revealed that some plucky mosses in Canada managed to do something long thought impossible: survive a 400-year close encounter with the business end of a glacier, and live to sprout another day. The conventional wisdom on glaciers was that they were Earth-scraping, life-razing forces of geology. Nothing could survive their [...]

Mosses Make Two Different Plants From the Same Genome, and a Single Gene Can Make the Difference

One of the most astonishing secrets in biology is this: every plant you see makes two different plants from the same genome. And, scientists recently reported, a single gene from an ancient, powerful lineage can make the difference. How can such a truth be so little known? In most land plants, including conifers and flowering [...]
