Scientists have discovered a mutation in the Omicron BA.5 subvariant, allowing it to efficiently infect lung cells. This development could lead to more severe disease outcomes, especially in high-risk groups. The study emphasizes the importance of ongoing monitoring of Omicron subvariants’ evolution.Future SARS-CoV-2 variants may also regain the ability to infect the lower respiratory tract.Omicron-derived virus variants currently account for the majority of SARS-CoV-2 infections globally. Compared to its predecessors,…

New strategies to save boats from the orca uprising are in the works.

Dubbed ‘Migraine,’ it shows why it’s vital to update your Mac as soon as possible. Migraine is so damaging because it can bypass Apple’s System Integrity Protection, or SIP for short. SIP is enabled by default on modern Macs and works by sandboxing sensitive parts of the computer from outside meddling. Only processes that are signed by Apple (or those with special privileges, like Apple…

While the variety of methods, targets, and motivations suggest the attacks are isolated events, they’ve further exposed the vulnerabilities of government targets. The attacks form part of a…

Each colored ribbon represents a DNA barcode. As the tumor evolves, some cancer cells come to dominate the tumor, shown by the orange and red ribbons. This shows these cancer cells have a pre-existing ability to escape the immune system and can carry on growing, even after treatment.
