Hello and welcome to Backchat, Nature's monthly peak behind the curtains of the newsroom. If the Nature

podcast is a seminar from a visiting professor, then Backchat is a journal club led by sarcastic

undergraduates. We're here to discuss the science we've been mulling over for the past month or so.

I'm Kerry Smith and I'm delighted to have with me three of Nature's best, as always. I have

Davidey Castilevecci in the studio.

Hi, Carrie. Yes, I am physical sciences and occasionally mathematics writer.

We also have Lizzie Gibney in the studio. Hello, I also write about physics and I'm also based

here in London. And Alexandra Witsy joining us on the line from Boulder, Colorado. Yes, good morning,

Carrie. I cover Earth and planetary sciences and also sometimes some astronomy for nature.

Great news. All right. Well, coming up in this show, the revelation that renowned astronomer Jeff Marcy sexually harassed several students over a period of many years. How has astronomy as a community responded and what are the implications even further afield? Plus reporting on mathematics and mathematicians. Davidae had that pleasure

this month and will be reporting back to us on what it's like to cover the abstract concepts

and colourful personalities of that field. And finally some light relief in the form of fashion science, from the dress

that displays the wearer's Twitter feed, mine would be so interesting, to nanoparticles

that promise superior stain repellent, for instance, some fashion designers are scienceing the

hell out of their clothing ranges. Well, first, to astronomer Jeff Marcy and the fallout

from the sexual harassment case. On the 9th of October, it was revealed astronomer Jeff Marcy and the fallout from the sexual harassment case.

On the 9th of October, it was revealed by BuzzFeed that the University of California, Berkeley, Jeff Marcy's institution, had investigated him and found that he had sexually harassed several students in many separate incidents.

And days afterwards, he resigned.

Alex Switzie, you reported on this for nature. What actions

first of all did the university take? Well, it's been a very interesting story because it's pretty
