Why does DNA spontaneously mutate? Quantum physics might explain.
Quantum mechanics, which rules the world of the teensy-tiny, may help explain why genetic mutations spontaneously crop up in DNA as it makes copies of itself, a recent study suggests.

Quantum Bio·Inorganic Chemistry Society
The QBtopIC series is a new activity of the QBIC Society (www.qbicsoc.org). In these panel meetings, a discussion leader speaks with a number of invited experts on a topic that is of interest to the wider QBIC community and takes questions from the audience.
How to participate
Each meeting starts with a general introduction of the topic by the discussion leader, followed by short statements by the invited experts to highlight specific aspects. The remainder of the meeting is intended as a general discussion between the panel members with questions from the audience. In total the QBtopIC discussions should take 60-90 minutes.
You can put forward your questions or comments in the following ways:
– before the session as an e-mail to the discussion leader
– during the session through Twitter with the hashtag #QBtopIC #question
– during the session through the Zoom chat function
The QBIC Society plans to organise QBtopIC meetings on a monthly basis. If you have a topic in mind or an expert you would like to hear, please contact Vera Krewald via e-mail.

An atom shuffles its electrons at ultrahigh speed — and is caught in the act
Scientists capture the movement of electrons in a xenon atom, a phenomenon that lasts for a fraction of one-billionth of a second.
The new semi-empirical method GFN2-xTB by Grimme is a revolution on quantum chemistry calculations. It works for transition metals and representative elements as well. It can perform molecular dynamics, optimizations, vibrational analysis and works with or without periodic boundary conditions.
It is free and easy to install.

CALYPSO (Crystal structure AnaLYsis by Particle Swarm Optimization) is an efficient structure prediction method and its same-name computer software. The approach requires only chemical compositions for a given compound to predict stable or metastable structures at given external conditions (e.g., pressure), thus the CALYPSO package can be used to predict/determine the crystal structure and design the multi-functional materials (e.g., superhard).
