Compiler optimizations expose hidden UB risk in C/C++ type punning

A developer traced a hard-to-find bug to type punning via pointer casts, which behaves correctly at -O0 but breaks under -O2 optimization. The root cause is that pointer casts violate strict aliasing rules and constitute undefined behavior in C, even though they compile and run correctly on most platforms, and C++ treats type distinctions even more strictly than C.

Scientists identify over 20 distinct forms of cell death, including newly named 'alkaliptosis'

Researchers led by Daolin Tang discovered a novel form of cell death, dubbed alkaliptosis, triggered when a cell's internal pH becomes unusually high rather than through known mechanisms like necrosis or apoptosis. This finding is part of a broader wave of research since 1999 that has expanded the catalog of known cell-death pathways from two classical types to roughly 20 distinct processes, thanks to advances in gene editing, imaging and omics technologies.
