Researchers have quantified the astonishingly high speeds at which future solar cells would have to operate in order to stretch what are presently seen as natural limits on their energy conversion efficiency.
Varun Warrier grew up in southern India and is now a PhD student at St John's researching the genetics of autism. 
The unlikely coincidence of a local hospital record and a census led by a pioneering physician (and St John's alumnus) enabled College Fellow Simon Szreter to undertake the first study charting rates of venereal disease in 18th century England, revealing high infection levels in the city of Chester at this time.
Several St John's College students have recently been awarded prizes by the University or other academic institutions thanks to their excellent work and achievements.Yayaati Chachan, 4th year undergraduate in Natural Sciences, was awarded the Institute of Astronomy Prize.Tanmay Dixit, 3rd year undergraduate in Natural Sciences, won the Frank Smart Prize for Zoology.Clementine Makower, 3rd year undergraduate in Geography, was awarded both the William Vaughan Lewis Prize and the George Aldridge Prize.
Applications are invited for Research Fellowships at St John’s College. These positions are intended for outstanding researchers in the early stages of their careers. The Fellowships offer an opportunity to carry out independent research in a stimulating and supportive academic environment. Applications will be accepted from any graduate of a university within or outside the United Kingdom. For further details, please see https://sjcamrf.flexigrant.com/
Researchers led by College Fellow Tuomas Knowles have manufactured microscopic versions of the cocoons spun by silkworms, which could be used to store sensitive proteins and other molecules for a wide range of uses.Microscopic versions of the cocoons spun by silkworms have been manufactured by a team of researchers. The tiny capsules, which are invisible to the naked eye, can protect sensitive molecular materials, and could prove a significant technology in areas including food science, biotechnology and medicine.
Three Johnians were successful at the Royal Academy of Engineering Awards, presented by The Duke of Kent. The winner of the MacRobert Award, the top Royal Academy of Engineering Award for innovation, was Raspberry Pi. Dr Eben Upton CBE, a St John’s alumnus, is the CEO of the organisation, and Dr Robert Mullins, Fellow of St John’s and University Lecturer in Computer Science, is a co-founder of the Raspberry Pi Foundation.
In a study co-authored by St John's Fellow Simon Conway Morris, researchers show how major changes in the chemical composition of the world’s oceans enabled the first large organisms – possibly some of the earliest animals – to exist and thrive more than half a billion years ago. 
Julia Gottwald, PhD Psychiatry candidate, has won the Association of British Science Writers Best Student Science Journalist Award.Julia won the Best Student Science Journalist Award for her article entitled Does your brain have a sex? which was published by BlueSci, the Cambridge University Science Magazine, Easter 2016.Julia, a third year PhD student at the Department of Psychiatry and a member of St John’s, shows in her winning article that human male and female brains are more similar than we think.
College Research Associate Dr Akshay Rao has been awarded the Henry Moseley Medal and Prize for exceptional early career contributions to experimental physics.Dr Akshay Rao, a Research Associate at St John’s, has been awarded the Henry Moseley Medal and Prize for “groundbreaking studies into the electronic properties of organic semiconductors, particularly the roles of electron spin in the operation of solar cells.”
