Scientists and researchers from various countries are collaborating on projects during the X Antarctic Expedition aboard the Colombian research vessel 'ARC Simon Bolivar,' designed exclusively to develop scientific projects. These initiatives involve analyzing the current condition of the Antarctic sea, studying atmospheric pressure, and monitoring the species inhabiting this region of the planet. .

Gaming on Linux has never been better—but that doesn't mean your distros are free from security threats. Case in point is a severe vulnerability nicknamed 'Copy Fail,' which allows a local user to dig into the guts of the OS and give themselves root privileges merely by writing four bytes of controlled data into the page cache of any readable file.

The security research team at Theori disclosed the vulnerability last Wednesday, though CISA reports that threat actors have since been observed using the exploit in the wild. The security flaw has been given the designation CVE-2026-31431 and marked with a high severity score of 7.8 (via Bleeping Computer).
