Twitter may have lost over a million users since Elon Musk took over
The news: In the days since Elon Musk confirmed his purchase of Twitter on Oct. 27, tweeting “the bird is free,” many Twitter users have threatened to walk away. But while people often don’t follow through on threats to quit Twitter, new data suggests that a significant number of users are actually leaving the platform.
How they did it: The firm Bot Sentinel, which tracks behavior on Twitter, believes about 877,000 accounts were deactivated and another 497,000 were suspended between October 27 and November 1. This is more than double the usual figure.
Why it matters: Anecdotal evidence from social media suggests that people upset about Elon Musk’s purchase of Twitter are following through and choosing to deactivate their accounts in protest. If they continue to do this en masse, this could be a major problem for the platform and its new owner. Read the whole story.
Data from drivers’ smartphones could help detect when bridges need urgent repairs
Smartphones could be used to monitor the safety of bridges much more quickly and cheaply than is currently possible, providing engineers with data they can use to fix structures before they become dangerously unstable.
Typically, the state of repair of bridges is monitored by visual inspection for cracks and failures, or by sensors that collect their vibration and movement data. But a new method developed by researchers at West Point Military Academy and other universities avoids the need to collect accelerometer data from smartphones in cars as they drive over bridges.

Here’s how personalized brain stimulation could treat depression
Sending a jolt of electricity through a person’s brain can do remarkable things. Just watch the videos of people with Parkinson’s disease who have electrodes implanted in their brains. They can go from struggling to walk to walking confidently across a room, literally with the flip of a switch.
We could use a similar approach to boost our mood, something that could be life-changing for people with disorders like depression. And we’re not just talking about general brain zaps, the goal is to create custom devices that track your brain activity and optimize it. Read the whole story.

This week, MIT Technology Review held our annual EmTech conference, our flagship event covering emerging technology and global trends.
Check out our live blogs covering two days of fascinating discussions with global change-makers, innovators and industry veterans as we try to sort out what’s likely, plausible and possible with tomorrow’s breakthrough technologies.
The first day focused on some of the exciting technologies that promise to change our lives, such as clean energy and CRISPR, while the second day showed what the future holds for the Internet, augmented reality, technology body and the AI.
I’ve combed the internet to find you the funniest/important/scary and fascinating stories about technology.

The great story
I asked my students to hand in their cell phones and write about living without them
A few years ago, Ron Srigley, a writer who teaches at Humber College and Laurentian University, conducted an experiment in a philosophy class he was teaching. His students had failed a test rather poorly, and he had a hunch that his widespread use of cell phones and laptops in class was partly responsible.
He offered them extra credit if they gave him their phones for nine days and wrote about living without them. Twelve students—about a third of the class—accepted the offer. What they wrote was remarkable, and remarkably coherent. Read the whole story.
