Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria in root nodules. But a recent discovery upends that rule.
AI has come to the hiring process — and it’s made those mandatory personality tests all the weirder.
As 404 Media reports, companies as disparate as McDonald’s, Olive Garden, and FedEx are now requiring that job applicants take personality evaluations, which are then sorted by an AI system whose operations are cloudy at best.
The aforementioned companies are all contracted with Paradox.ai, a “conversational recruiting software” company whose strange personality assessments include images of blue-skinned humanoid aliens that applicants are, apparently, supposed to identify with.

Professor Peter Atkins is a fellow of Lincoln College in the University of Oxford and the author of about seventy books for students and a general audience. His texts are market leaders around the globe. A frequent lecturer in the United States and throughout the world, he has held visiting professorships in France, Israel, Japan, China, and New Zealand. He was the founding chairman of the Committee on Chemistry Education of the International Union of Pure and Applied Chemistry and was a member of IUPAC’s Physical and Biophysical Chemistry Division. Peter was the 2016 recipient of the American Chemical Society’s Grady-Stack Award for science journalism.
Jim Baggott is a freelance science writer. He was a lecturer in chemistry at the University of Reading but left to work with Shell International Petroleum Company and then as an independent business consultant and trainer. His many books include Mass: The quest to understand matter from Greek atoms to quantum fields; Higgs: The Invention and Discovery of the ‘God Particle’; and The Quantum Story: A History in 40 Moments.

The laws of nature or physics are assumed to be everywhere the same, on the far side of the universe as sure as on the far side of your house. Otherwise science itself could not succeed. But are these laws equally constant across time? Might the deep laws of physics change over eons of time? The implications would be profound.

If the deep laws of the universe had been ever so slightly different human beings wouldn’t, and couldn’t, exist. All explanations of this exquisite fine-tuning, obvious and not-so-obvious, have problems or complexities. Natural or supernatural, that is the question.

Quantum computers, systems that process and store information leveraging quantum mechanical phenomena, could eventually outperform classical computers on numerous tasks. Among other things, these computers could allow researchers to tackle complex optimization problems, speed up drug discovery and better protect users against cyber-security threats.
