Ancient seaweed that have been found growing in the deep sea are "living fossils", researchers have reported. The two types of seaweed, which grow more than 200m underwater, represent previously unrecognised ancient forms of algae, say the scientists. As such, the algae could belong to the earliest of all known green plants, diverging up to one billion years ago from the ancestor of all such plants.

More than 35,000 new species of flowering plants may be lying undiscovered in cupboards around the world, it is claimed. Botanists looked at how long it takes for new species collected in the field to be identified, and found it often took decades. They concluded that of the 70,000 flowering plants that experts believe are yet to be found, over half may already be in collections, awaiting identification.

Are You Being Controlled ... By Corn? What if humans are all just pawns in a clever strategy game masterminded by corn? In this video, author Michael Pollan asks you to see things from a plant's-eye view -- to consider the possibility that nature isn't opposed to culture, and that biochemistry rivals intellect as a survival tool. By merely shifting your perspective, perhaps you can help heal the Earth.

MicroRNAs from common plant crops such as rice and cabbage can be found in the blood and tissues of humans and other plant-eating mammals, according to a study published today in Cell Research. One microRNA in particular, MIR168a, which is highly enriched in rice, was found to inhibit a protein that helps removes low-density lipoprotein (LDL) from the blood, suggesting that microRNAs can influence gene expression across kingdoms.
