When a fertilized mammalian egg divides, it yields two seemingly identical daughter cells. Some of their descendants generate the diverse organ systems of the embryo, while others form extra-embryonic tissues that sustain the developmental process. In 2025, researchers used a cutting-edge technique known as single-cell proteomics (SCP) to show that even in the two first-generation

Winter near the Antarctic Circle brings months of frozen darkness, when sea ice chokes ocean waters and many of its denizens hunker down to ride out the harsh conditions. But as winter began to release its icy grip, an uncommonly clear satellite image revealed that part of this remote realm was still very much awake,
