Identifying the full extent of the nuclear landscape, essentially how many isotopes exist, is vital for nuclear physics. There is a lot left to learn. Beyond the stable nuclei that we find on Earth, there are many unstable nuclei that are formed in stellar events such as supernovae, but which are short-lived. There is a limit to how many protons and neutrons a nucleus can hold – too many and the excess will literally ‘pop out’. These limits are known as the proton and neutron
A Star that seems Brighter when Eclipsed1: Variable StarThis paradoxical phenomenon was brought to my attention by a recent article in Physics World. Quite an informative article, but like some bard of old, with legendary tales of kings and heroes, I would like to tell the story in my own way.
You know what is really impressing me about Neil deGrasse Tyson’s Cosmos? That he doesn’t hesitate to draw connections between science and how we live our lives — there is an implicit understanding that science has become fundamental to how we see the universe. Last night’s episode was no exception. What started as an explanation…
ReferralPlus is a tool to match patients who disqualify for one study with others they might qualify for, using a geo-therapeutic matching algorithm with other studies, similar to how OpenTable matches people with the restaurants they are interested in by using demographic and time availability algorithms. It was created because 95% of patients who respond to a trial recruitment advertisement do not qualify and/or enroll in that study. Most of those patients never enroll in another
