# Scientists: Unfortunately, Bacteria Scream When They Die

## Necrosignaling

Here's a pleasant thought for next time you spray down your kitchen counter — scientists say that bacteria "scream" as they die, giving off chemical alarms that warn their brethren of danger.

Specifically, [*Live Science* reports](<https://www.livescience.com/bacteria-death-screams.html>), swarming bacteria like *E. coli* appear to be able to detect the presence of danger such as antibiotics, and "necrosignal" to their compatriots as they die so that they can start mutating a resistance to it.

## Meme Culture

*Live Science* reports that the University of Texas at Austin researchers behind new research [published in the journal *Nature*](<https://www.nature.com/articles/s41467-020-17709-0#Abs1>) were intrigued by the fact that antibiotics often only seem to kill some of a bacteria swarm.

On further investigation, they found that when antibiotics hit a swarm of *E. coli*, the dying bacteria send out a chemical signal that prompts their neighbors in the swarm to start rapidly adapting to the threat, increasing their chances of survival.

## Dead Cells

It's an intriguingly microscopic example of pro-social behavior — an adaptation that doesn't help an individual survive, but does let it use its death to help others, therefore making the entire swarm more likely to survive and reproduce.

"Dead cells are helping the community survive," University of Texas at Austin professor of molecular biosciences told *Live Science*.

## Author
I'm responsible for editing, assigning, and scouting at Futurism, as well as occasionally writing for the site. That work involves keeping an eye on a wide range of narratives and issues, but over the past few years I've become increasingly interested in how AI is shaping the future of media, the web, and information itself. My day-to-day often involves collaborating on reporting and commentary projects bylined by my colleagues, but I try to find time to do my own reporting as well; stories I've broken for Futurism have been cited by publications including the New York Times, the Washington Post, the New Yorker, Wired, Ars Technica, New York Magazine, the Columbia Journalism Review, Bloomberg, and more. I grew up in Southern Vermont and attended Vanderbilt University. Prior to Futurism, I contributed to outlets including the Boston Globe, Vice, Wired, Slate, the Atlantic, the Outline, Ars Technica and more, and did stints in farming and food service. I currently live in Brooklyn, New York, and in my free time I enjoy pinball, word games, cycling, running, and music production.
