Lymphatic vessels were first described by Hippocrates; centuries later, we’re still learning about them. Weizmann’s Dr. Karina Yaniv recently discovered that the lymphatic system does not develop as previously thought. Interestingly, says The Scientist, after all these years, three other studies on lymph vessel origin came out at the same time.
As the old song says, “oops, there goes another rubber tree plant.” People have always been in awe of ants’ ability to work together to get the seemingly impossible done – but how, exactly, do they do it? Now we know, thanks to a Weizmann team that created a physics-based model showing how groups of ants cooperate to carry large pieces of food to the nest.
