Crustaceans have evolved to have crab-like bodies enough times that scientists had to create a name for the weird phenomenon: carcinisation. Evolution has remade crabs no less than five times over the past 250 million years, but not all of them are even true crabs in the taxonomic sense. Although many true and false crabs have similar body shapes, like flattened carapaces, one noticeable difference is that false crabs don’t use all four pairs of their legs to walk; their last set is too small and sits at the rear.

‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
