The study resolves a biological blind spot that persisted since 5-oxoETE was first identified by McGill University researchers in 1992. By utilizing zebrafish and building on work by King Lam Hui, PhD, scientists Philipp Niethammer, PhD, and Yanan Ma, PhD, successfully isolated the human gene controlling the molecule's regulatory enzyme. Unlocking this dual-function molecule provides researchers with the genetic tools needed to study its behavior in complex human illnesses. Consequently, this breakthrough could pave the way for novel therapies targeting asthma, cancer, and inflammatory bowel disease.

Scientists have solved a biological mystery that remained unanswered for more than three decades, uncovering an unexpected way the immune system protects the body from its own inflammatory response. The breakthrough reveals that a chemical signal responsible for attracting immune cells to fight infections also helps prevent those same defenses from damaging healthy tissue.
The discovery came from researchers at Memorial Sloan Kettering Cancer Center (MSK), who took an unusual approach to studying inflammation. Rather than relying on mice, a standard choice for biomedical research, they turned to zebrafish. That decision helped them identify a long-mysterious enzyme and uncover a protective mechanism that had previously escaped scientists.

Scientists studying the endangered ʻakiapōlāʻau honeycreeper have uncovered the anatomical adaptations that allow it to occupy an ecological niche typically filled by woodpeckers. By examining museum skeletons, researchers discovered specialized leg structures and a uniquely flexible bill that make this demanding foraging possible. These sophisticated physical demands also explain why young birds require an extended period of parental care to master hunting.
Engineering teams from KAIST and Georgia Tech have engineered a low-cost membrane from porous polyacrylonitrile that separates crude oil at room temperature. The innovation transforms conventional fouling into an operational benefit by letting heavy hydrocarbons naturally narrow membrane pores. This breakthrough provides an alternative to traditional, heat-heavy distillation, significantly lowering industrial energy requirements and associated carbon output.
Researchers analyzing ancient enamel proteins from East Asian fossils have uncovered evidence of interbreeding between *Homo erectus* and Denisovans. This genetic exchange ultimately passed ancient material down to modern humans across Southeast Asia and Oceania, directly refuting the longstanding belief that *Homo erectus* vanished without leaving any descendants.
