BREAKING: The world's most sensitive dark matter detector has announced it has spotted something it can't easily explain: a single event that's tantalizingly consistent with a type of theorized dark matter particle. Very early days yet, but pretty wild. 🧪 www.science.org/content/arti...
World’s biggest dark matter detector spots a single weird particle
It’s far too early to declare a discovery, physicists with the LZ detector say

🚨ALERT🚨 In our new paper, published in Microbiome, we show how host-mediated selection can produce microbiomes that enhance plant fitness under salt stress by up to ~198%. We explore the mechanisms behind these benefits and how our protocol shaped microbial community structure.

A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.
