Shell life species not competitors as they adjusted to Earth’s largest extinction

Research revealed that both brachiopods and bivalves shared similar trends in diversification dynamics during the Permian-Triassic mass extinction. The study found that bivalves eventually prevailed due to better adaptation to high ocean temperatures, while brachiopods retreated to deeper waters.

In cancer immunotherapy, more isn’t necessarily better

New research from Cold Spring Harbor Laboratory suggests that high tumor mutation burden does not guarantee an effective immune response in patients with mismatch repair deficiency. The study found that tumors with identical mutations across all cells responded to immunotherapy, while those with subclonal mutations did not.
