• ## Google Could Be Looking To Bring End-To-End Encryption To RCS Messages

SMS and MMS have been around for a while now, but it’s safe to say that they haven’t necessarily been updated to keep up with the times, and have since been replaced by the likes of messaging apps like WhatsApp, Telegram, Facebook Messenger, and so on. However, with RCS messages, that is set to change.

However, there is still at least one feature that other apps have that RCS doesn’t, and that is end-to-end encryption. The good news is that according to an APK teardown by 9to5Google, they have discovered evidence that Google could be looking to build end-to-end encryption into RCS messages in the future for its Google Messages app.

Based on the teardown, they have discovered as many as 12 strings that make reference to encryption, hinting that this is a feature that could be coming soon. For those who are unfamiliar, end-to-end encryption is a security

• ## A Grad Student Solved the Epic Conway Knot Problem—in a Week

To make a knotted object in four-dimensional space, you need a two-dimensional sphere, not a one-dimensional loop. Just as three dimensions provide enough room to build knotted loops but not enough room for them to unravel, four dimensions provide such an environment for knotted spheres, which mathematicians first constructed in the 1920s.

It’s hard to visualize a knotted sphere in 4D space, but it helps to first think about an ordinary sphere in 3D space. If you slice through it, you’ll see an unknotted loop. But when you slice through a knotted sphere in 4D space, you might see a knotted loop instead (or possibly an unknotted loop or a link of several loops, depending on where you slice). Any knot you can make by slicing a knotted sphere is said to be “slice.” Some knots are not slice—for instance, the three-crossing knot known as the trefoil.

Slice knots “provide

• ## Judge Rules That Looking At A Phone’s Lock Screen Could Require A Search Warrant

Law enforcement agencies are currently pretty miffed at companies like Apple and Google who have made it harder for them to access devices. This is because these companies have basically handed over the encryption keys to the user, meaning that only the user can unlock their devices and there’s really nothing that these companies can do.

Now it looks like things are about to get tougher for these law enforcement agencies because a Seattle-based District Judge has recently ruled that unless the police have a search warrant, even viewing the lock screen of a handset can be considered as a search. This means that without a warrant, it violates the person’s Fourth Amendment rights.

This stems from a case back in 2019 where a man by the name of Joseph Sam was arrested and indicted on charges related to robbery and assault. A year later when the FBI obtained the
