Toward testing the quantum behavior of gravity: A photonic quantum simulation

In a development at the intersection of quantum mechanics and general relativity, researchers have made significant strides toward unraveling the mysteries of quantum gravity. This work sheds new light on future experiments that hold promise for resolving one of the most fundamental enigmas in modern physics: the reconciliation of Einstein’s theory of gravity with the principles of quantum mechanics.

TB studies illustrate the importance of properly assessing the risks of pathogen research

It is true that the next pandemic is a matter of “when,” not “if.” The statistical certainty of a future pandemic has led to increasing research into potential pandemic pathogens so that we may create lifesaving countermeasures. Such research, unfortunately, also carries a risk of bringing about exactly what it seeks to prevent. Human error or even deliberate action is as likely to be the cause of the next pandemic as natural origin. Such concerns have intensified after the COVID-19 pandemic, which a significant percentage of the US population, at least, believes began with a research accident, one of the two main pandemic origin theories, with the other being the jump of a virus from animals to people. The question then for governments and the research community is how to build confidence in the valuable work that scientists do through appropriate regulation.

While research with favorable risk-benefit profiles must be facilitated, high-risk research of either limited benefits or benefits for only a limited few must be seen through a different regulatory lens.
