A team of researchers has discovered that tiny clusters of single-celled organisms that inhabit the world’s oceans and lakes, are capable of navigating their way to oxygen. Writing in e-Life scientists at the University of Cambridge describe how choanaflagellates, the closest relatives of animals, form small colonies that can sense a large range of concentrations of oxygen in the water. The research offers clues as to how these organisms evolved into multi-cellular ones.
Species of single-celled algae use whip-like appendages called flagella to coordinate their movements and achieve a remarkable diversity of swimming gaits.
Researchers have captured the first 3D video of a living algal embryo turning itself inside out, from a sphere to a mushroom shape and back again. The results could help unravel the mechanical processes at work during a similar process in animals, which has been called the “most important time in your life.”
Cutting-edge science, and its communication to the public, is often brought to life with sophisticated imagery. But how do you go about photographing a distant star formation or the inside of a locust’s brain? Cambridge researchers and technicians reveal all.
Using high-speed microscopic imaging, Professor Raymond Goldstein's group in the Department of Applied Mathematics and Theoretical Physics has demonstrated how the interactions of microbes such as sperm cells and algae with solid surfaces are considerably more complex than previously thought.
