Facebook finally adds option to delete old posts in batches

Got any embarrassing old posts collecting dust on your profile? Facebook wants to help you delete them.

Facebook finally adds option to delete old posts in batches

  • The feature is called Manage Activity, and it's currently available through mobile and Facebook Lite.
  • Manage Activity lets users sort old content by filters like date and posts involving specific people.
  • Some companies now use AI-powered background checking services that scrape social media profiles for problematic content.

Facebook is rolling out a new feature designed to help users delete old posts in bulk instead of one at a time.

The company announced Tuesday that its "Manage Activity" tool will allow users to delete posts en masse, or archive them so that they're accessible only to the user. Manage Activity will let users organize old content in batches, sorted by filers like specific date range and posts involving certain people.

Manage Activity is available today on mobile and Facebook Lite, and the company says it'll be functional for desktop users in the future.

"Whether you're entering the job market after college or moving on from an old relationship, we know things change in people's lives, and we want to make it easy for you to curate your presence on Facebook to more accurately reflect who you are today," Facebook wrote in a statement. "That's why we're launching Manage Activity to help you archive or trash old posts, all in one place."

Facebook

Why is Facebook releasing the feature now? A company spokesperson told Recode that users and privacy advocates have long requested better control over past posts. Users have had access to the "limit past posts" option, which blocks the public from accessing a user's posts past a certain date. But there has been no way to delete old content in batches.

Social media background checks


Now, the feature could bring users some peace of mind. After all, the platform currently has more than 2.6 billion monthly active users, and some of these users created accounts in their teens, around the time Facebook became widely available in 2006. As these veteran users get older, it seems likely that many would want to delete years-old posts, whether because content is embarrassing, outdated or professionally jeopardizing.

Some employers now use automated or third-party background checks that scrape candidates' social media accounts. These checks can search for content that's racist, sexually explicit, criminal or otherwise offensive.

But they're not always accurate. One AI-powered background service called Checkr has even faced lawsuits from people who claim the company's algorithms made mistakes that cost them job opportunities.

How to use Manage Activity

It's unclear when Manage Activity will become available on desktop. But to learn how to use it on mobile or Facebook Lite, check out this instructional video from Facebook.

This is what aliens would 'hear' if they flew by Earth

A Mercury-bound spacecraft's noisy flyby of our home planet.

Surprising Science
  • There is no sound in space, but if there was, this is what it might sound like passing by Earth.
  • A spacecraft bound for Mercury recorded data while swinging around our planet, and that data was converted into sound.
  • Yes, in space no one can hear you scream, but this is still some chill stuff.

First off, let's be clear what we mean by "hear" here. (Here, here!)

Sound, as we know it, requires air. What our ears capture is actually oscillating waves of fluctuating air pressure. Cilia, fibers in our ears, respond to these fluctuations by firing off corresponding clusters of tones at different pitches to our brains. This is what we perceive as sound.

All of which is to say, sound requires air, and space is notoriously void of that. So, in terms of human-perceivable sound, it's silent out there. Nonetheless, there can be cyclical events in space — such as oscillating values in streams of captured data — that can be mapped to pitches, and thus made audible.

BepiColombo

The European Space Agency's BepiColombo spacecraft took off from Kourou, French Guyana on October 20, 2019, on its way to Mercury. To reduce its speed for the proper trajectory to Mercury, BepiColombo executed a "gravity-assist flyby," slinging itself around the Earth before leaving home. Over the course of its 34-minute flyby, its two data recorders captured five data sets that Italy's National Institute for Astrophysics (INAF) enhanced and converted into sound waves.

Into and out of Earth's shadow

In April, BepiColombo began its closest approach to Earth, ranging from 256,393 kilometers (159,315 miles) to 129,488 kilometers (80,460 miles) away. The audio above starts as BepiColombo begins to sneak into the Earth's shadow facing away from the sun.

The data was captured by BepiColombo's Italian Spring Accelerometer (ISA) instrument. Says Carmelo Magnafico of the ISA team, "When the spacecraft enters the shadow and the force of the Sun disappears, we can hear a slight vibration. The solar panels, previously flexed by the Sun, then find a new balance. Upon exiting the shadow, we can hear the effect again."

In addition to making for some cool sounds, the phenomenon allowed the ISA team to confirm just how sensitive their instrument is. "This is an extraordinary situation," says Carmelo. "Since we started the cruise, we have only been in direct sunshine, so we did not have the possibility to check effectively whether our instrument is measuring the variations of the force of the sunlight."

When the craft arrives at Mercury, the ISA will be tasked with studying the planets gravity.

Magentosphere melody

The second clip is derived from data captured by BepiColombo's MPO-MAG magnetometer, AKA MERMAG, as the craft traveled through Earth's magnetosphere, the area surrounding the planet that's determined by the its magnetic field.

BepiColombo eventually entered the hellish mangentosheath, the region battered by cosmic plasma from the sun before the craft passed into the relatively peaceful magentopause that marks the transition between the magnetosphere and Earth's own magnetic field.

MERMAG will map Mercury's magnetosphere, as well as the magnetic state of the planet's interior. As a secondary objective, it will assess the interaction of the solar wind, Mercury's magnetic field, and the planet, analyzing the dynamics of the magnetosphere and its interaction with Mercury.

Recording session over, BepiColombo is now slipping through space silently with its arrival at Mercury planned for 2025.

Study helps explain why motivation to learn declines with age

Research suggests that aging affects a brain circuit critical for learning and decision-making.

As people age, they often lose their motivation to learn new things or engage in everyday activities. In a study of mice, MIT neuroscientists have now identified a brain circuit that is critical for maintaining this kind of motivation.

  • MRI brain scans may show white spots that scientists believe are linked to cognitive decline.
  • Experts have had no objective means of counting and measuring these lesions.
  • A new tool counts white spots and also cleverly measures their volumes.
