Cracking the case: New study sheds more light on the ‘Brazil nut effect’

Share This Post

Why are there always numerous Brazil nuts topping a can of mixed nuts? Apparently, aside from being bigger and less dense than other nuts, their orientation in the can also plays a part; once the Brazil nuts are jostled into a vertical position, smaller nuts push the larger nuts upward, and those that stay horizontal stay at the bottom. Amusingly, the seemingly futile “Brazil nut effect” can be used by scientists to ensure “an even distribution of active ingredients in medicinal tablets” Read full article here

Magneto Protein Could Help Magnets Control Brain Circuitry

This groundbreaking research by scientists at the University of Virginia has demonstrated a novel way to control the nervous systems of zebrafish and mice using magnets. This method, called magnetogenetics, involves inserting genetic constructs into neurons to make them sensitive to magnetic fields, providing a more precise and non-invasive way to control and manipulate neural circuits than traditional methods. This could one day revolutionize the treatment of brain disorders in humans. Read full article here
