New research reveals that only the oldest and fastest-sinking oceanic plates can transport water deep into Earth’s mantle, due to the unique heat-transferring properties of the mineral olivine.

Because of the way the mineral olivine conducts heat through radiation, only oceanic tectonic plates that are more than 60 million years old and moving downward at speeds greater than 10 centimeters per year are able to stay cool enough to carry water deep into the Earth’s mantle.

This conclusion comes from a team of researchers at the University of Potsdam and the Helmholtz Centre for Geosciences (GFZ) Potsdam, along with international partners. They reached this finding after measuring how transparent olivine is to infrared light under the extreme pressure and temperature conditions found within the Earth’s mantle. Their study was published in Nature Communications.

CISA added Citrix NetScaler’s CVE-2025–5777 to its KEV catalog as active exploits emerge worldwide. Immediate patching advised.

A critical vulnerability in mcp-remote (CVE-2025–6514) allows remote code execution, affecting 437,000+ users.

Van Leeuwen also cited the example of a group of chimpanzees at a zoo in the Netherlands in which one female started walking as if she were carrying a baby even though she wasn’t.

Soon, all of the females had adopted this walking style, he said. In addition, when two new females were brought into the group, the one that adopted the style swiftly was integrated quickly, whereas the one that refused to walk in the group style took longer to be accepted.

For Van Leeuwen, these behaviors are about fitting in and smoothing social relationships, just as with humans.

Microsoft’s July 2025 Patch Tuesday update resolves 130 vulnerabilities, including critical RCE and SQL Server flaws.

Microsoft is rolling out a new backup system in September for its Authenticator app on iOS, removing the requirement to use a Microsoft personal account to back up TOTP secrets and account names.

Previously, the Microsoft Authenticator app required iOS users to sign in with a personal Microsoft Account to enable backups, regardless of whether they were using the app for personal or enterprise credentials.

This created problems in enterprise environments where organizations often like to keep personal and corporate data separated.
