Due persone di 52 anni possono avere corpi che biologicamente differiscono di dieci anni. Gli orologi epigenetici — strumenti che analizzano i marcatori chimici sul DNA — riescono già a misurarlo, e a predire il rischio di malattie cardiovascolari, declino cognitivo e aspettativa di vita. Non è fantascienza: è già disponibile. Il problema è sapere come interpretare i risultati.

AI search grounded in Facebook posts? What could go wrong?

More AI search in more places.

AI is pretty reliable at putting things on your calendar these days, but it hasn't quite cracked answering the related and all-important question of "What should I do this weekend?" Meta's new AI Mode in search could be a useful tool - if it ever learns to stop getting stuff wrong.

AI Mode is a new option when you hit the search bar in the Facebook app. It's designed to tackle complex queries - much like AI Mode in Google Search. But Meta's version draws on public posts across Meta apps - including Facebook Groups and Instagram Reels - to inform its results. That could be useful, considering the neighborhood groups and local organizations a …

Threads hits 500M users as Meta rolls out new features

17 June 2026 at 10:24

Meta Platforms’ Threads app has reached 500 million monthly active users, marking a significant milestone for the platform as it moves to deepen engagement through a suite of new community tools and personalised feed controls.

The social media giant stated the growth has been driven largely by communities, which are groups of users sharing interests spanning books, basketball, parenting, and music.

To mark the milestone, Meta is graduating its communities feature out of beta and launching a series of updates aimed at making those groups more visible and easier to navigate.

The communities hub is being added to the main menu to the left of the feed, making it easier for users to find and switch between groups.

Communities will also get their own distinct icons to make them more recognisable across the platform, alongside a progress indicator showing users how close a topic is to achieving full community status and what they can do to help it get there.

Champion recognition is being expanded to more users across communities, with local communities launching in Japan, Korea and Taiwan with native-language tags.

Meta stated Live Chats will expand to more communities in the coming weeks, with co-hosting and the ability to quote moments directly to a user’s feed.

Your Algo
Alongside the community updates, Meta is introducing Your Algo, a new personal feed setting which builds on the Dear Algo feature launched in February.

While Dear Algo allowed users to tell the Threads algorithm what they wanted to see more or less of, Your Algo adds a private layer of control, letting users filter specific topics from their feed and set how long a request lasts across one, three or seven days. Both tools will be manageable from a single hub.

Your Algo rolled out in the US, Canada, UK, Australia, and New Zealand.

Meta stated the updates are the beginning of continued investment in the platform based on user feedback.

It launched Threads in July 2023 in a bid to compete against Elon Musk-owned X.

Un fisico georgiano ha calcolato che granelli di polvere sparati dall'atmosfera terrestre da impatti con micrometeoriti potrebbero aver trasportato batteri fino a Europa, la luna ghiacciata di Giove. Le probabilità di sopravvivenza sono bassissime, ma su scale di milioni di anni i numeri diventano enormi. Se un giorno trovassimo vita nell'oceano di Europa, potrebbe non essere aliena — potrebbe venire da qui.

Threads has surpassed 500 million monthly active users, Meta announced on Tuesday, hitting the milestone just shy of the platform's third birthday. Threads got off to a hot start in 2023, reaching 100 million users even faster than ChatGPT, and CEO Mark Zuckerberg has said that he thinks Threads could hit 1 billion users.

Meta says that daily active users on Threads continue to "increase strongly across the globe," with "all" of it driven by communities, which allow users to see and make posts about different topics. The company is bringing them out of beta and adding features like a communities hub in the Threads menu and giving communitie …

Your public Facebook posts could help inform AI-generated results in Meta's new AI Mode. When you search on Facebook, the "AI Mode" option will appear alongside the usual search modes like "People" and "Marketplace." It's one of several new AI features Meta is rolling out starting today, including photo presets that swap sports jerseys onto fans and suggestions for collage templates.

Instagram is going to let you tweak what its algorithm shows you on your main feed. With the Your Algorithm feature, "you can now see the topics we think you're interested in, and change them, across all the major parts of Instagram," according to Instagram boss Adam Mosseri. Right now, the feature will only surface topics, but Instagram is working on "supporting requests for people, different moods or vibes, content types, and more."

The company has been slowly giving users more agency over some algorithms on Instagram, having already launched the Your Algorithm feature for your Reels feed and the Explore page. With Wednesday's announcemen …
