Phycology is the scientific study of algae. Also known as algology, phycology is a branch of life science and often is regarded as a subdiscipline of botany.

No organs, no problem: Weird animal hunts algae without nerves or muscles

[USA] It’s amazing what can be accomplished without a brain. Ask Trichoplax. This tiny multicellular animal — only a millimeter across — has nothing recognizable as muscle or nerve cells. In fact it has no organs at all. And yet it can hunt down, dissolve and consume algae with surprising sophistication, new research shows.

Sea slug found to track seaweed by sniffing its defensive chemicals

[USA] A team of researchers with the Georgia Institute of Technology has found that one species of sea slug (Elysia tuca) uses chemicals produced defensively by one type of seaweed (Halimeda incrassata) to track down the seaweed. Continue reading Sea slug found to track seaweed by sniffing its defensive chemicals

One gene may drive leap from single cell to multicellular life

[USA] The leap from single-celled life to multicellular creatures is easier than we ever thought. And it seems there’s more than one way it can happen.

The mutation of a single gene is enough to transform single-celled brewer’s yeast into a “snowflake” that evolves as a Continue reading One gene may drive leap from single cell to multicellular life
