NewsResearchers undercover how macronucleophagy ensures survival in nitrogen-starved yeast
Scientists sought to shed light on how macronucleophagy ensures the survival of nitrogen-starved S. cerevisiae and revealed that uncontrolled micronucleophagy due to the lack of normal macronucleophagy causes cell death.

NewsPlant cells gain immune capabilities when it’s time to fight disease
New research reveals how plant cells switch roles to protect themselves against pathogens. When a threat is encountered, the cells enter a specialized immune state and temporarily become PRimary IMmunE Responder (PRIMER) cells.

NewsScientists advance nanobody technology to combat deadly Ebola virus
Researchers have developed the first nanobody-based inhibitors targeting the Ebola virus. Their small size allows them to access areas of the virus and human tissues that larger antibodies cannot.
