Key Highlights
•
Researchers have identified new drugs that block two key proteins, HIF-1 and HIF-2, which many cancers use to grow, spread, and hide from the immune system. These drugs not only shrank various tumors in animal studies but also made resistant cancers respond again to immunotherapy, offering a promising new dual-target approach to cancer treatment.

The proteins Bcl6 and Blimp1 have been pinpointed as the master regulators controlling the development of T follicular helper cells, a specialized type of immune cell critical for generating strong antibody responses. Understanding this “on/off switch” provides a fundamental insight into how our immune system fine-tunes its defenses, with implications for improving vaccines and treating autoimmune diseases.

A new global index ranks 117 marine mammal species—like whales, dolphins, and seals—by their vulnerability to large plastic pollution based on their risk of exposure, sensitivity, and ability to recover. This tool helps conservationists prioritize protection efforts for the most at-risk species, such as manatees and dugongs, by highlighting where plastic pollution poses the greatest threat.
