‘Good’ Bacteria Tries to Control Plant Immune Systems

A power struggle goes on underground between a plant and “good” bacteria as they vie over who will control the plant’s immune system.

Meet the cucumber plant, nature’s engineering equivalent of non-Newtonian fluid.

Their vine tendrils have to be pretty strong to hold and pull the plant up toward sunlight. To help them out, the vines have a design that when low amounts of stress are applied to them, they uncoil like a normal spring. The more stress you put on the spring however, the tighter it coils.

Harvard researchers mimicked the plant’s form and makeup to make an applicable design.

Another great example of how much we still have to learn from even the most common of inspirations! As well as some insight into the process of experimentation needed to develop even a relatively simple new technology.

That’s a mightily surprised corn stem! And a little on the creepy clown side.


There are around 30 wild species in the Gerbera genus, which most would recognize as daisies commonly sold as cut flowers. They come in a large variety of colors, and these are largely hybrids bred for looks, Gerbera hybridus. They are members of the Asteraceae family (which is a huge family, if you haven’t yet noticed).
As you can see in this picture, the pollen comes from the central disc of the flower. This is actually a disc of many tiny flowers, called disc florets. The outer “petals” are ray florets.

Just a happy little cross-section of a marram grass leaf!
