Twitter says it has launched new, more secure messages – but even chief executive Elon Musk has warned users not to “trust it”. The social network has long been working on encrypted messages, which ensure that messages cannot be intercepted while they are being delivered. That is already possible on most other major messaging platforms, such as WhatsApp and iMessage. Now Twitter has released what it says is the first step towards integrating that security technology into its own product. But it says that it is not fully safe, and that users should not rely on it to keep messages secure. “Early version of encrypted direct messages just launched,” Mr Musk wrote on Twitter. “Try it, but don’t trust it yet.” On its support pages, Twitter’s aim is that “if someone puts a gun to our heads, we still can’t access your messages”. But it says it is “not quite there yet” and still “working on it”. That suggests that the messages are not end-to-end encrypted. While messages are secured from some attackers, anyone at Twitter or with access to its servers may still be able to access them. What’s more, Twitter’s implementation comes with a host of other limitations. It is only available when both of the users are verified and pay for Twitter’s $8 a month service, and users must turn it on rather than it being enabled by default. The messages also cannot be sent to groups, include pictures or other attachments, cannot be joined by new devices, are only supported on a limited number of devices per account and do not have proper protection against certain cyber attacks. When those various conditions are satisfied, users will be informed they are having an encrypted conversation by a message that appears within the chat. The other user’s profile picture will also show a lock icon over it. Twitter said that it would be updating the feature to remove some of those limitations, and would provide more information about the technology underpinning it in releases later this year.

To the uninitiated, there isn’t much to water. Sure, the world’s oceans are filled with monsters, marvels and mysteries but, otherwise, they’re just vast, singular expanses of liquid. Right? Wrong. Far from being uniform everywhere, ocean water is a patchwork of interlinked layers and masses which mix and split apart thanks to currents, eddies, and changes in temperature or salinity. Indeed, beneath the surfaces of our great seas, there are waterfalls, rivers and even gigantic blobs, stretching thousands of miles, that somehow manage to evade detection. Now, scientists have discovered one of these massive blobs in the middle of the Atlantic Ocean; extending from the tip of Brazil to the Gulf of Guinea. Until the discovery of this water mass – which has been named the Atlantic Equatorial Water – experts had seen waters mixing along the equator in the Pacific and Indian oceans, but never in the Atlantic. "It seemed controversial that the equatorial water mass is present in the Pacific and Indian oceans but missing in the Atlantic Ocean because the equatorial circulation and mixing in all three oceans have common features," Viktor Zhurbas, a physicist and oceanologist at The Shirshov Institute of Oceanology in Moscow, told Live Science. "The identified new water mass has allowed us to complete (or at least more accurately describe) the phenomenological pattern of basic water masses of the World Ocean." As the name suggests, the Atlantic Equatorial Water is formed by the mixing of separate bodies of water by currents along the equator. To distinguish such masses from the water surrounding them, oceanographers analyse the relationship between temperature and salinity across the ocean — which determines the density of the seawater. Back in 1942, this charting of temperature-salinity led to the discovery of equatorial waters in the Pacific and Indian oceans, as Live Science notes. Because they are created by the mixing of waters to the north and south, the Indian and Pacific Equatorial waters share similar temperatures and salinities curving along lines of constant density, which make them easy to distinguish from the surrounding water. And yet, for years, no such relationship could be spotted in the Atlantic. However, thanks to data collected by the Argo programme – an international collection of robotic, self-submerging floats which have been installed across Earth’s oceans – the researchers spotted an unnoticed temperature-salinity curve located parallel to the North Atlantic and South Atlantic Central waters. This was that elusive Atlantic Equatorial Water. "It was easy to confuse the Atlantic Equatorial Water with the South Atlantic Central Water, and in order to distinguish them it was necessary to have a fairly dense network of vertical temperature and salinity profiles covering the entire Atlantic Ocean," Zhurbas explained in his email to Live Science. The discovery is significant because it offers experts a better understanding of how oceans mix, which is vital to how they transport heat, oxygen and nutrients around the world.
