NewsResearchers uncover control mechanisms of polysaccharide utilization in gut bacterium
Polysaccharide utilization loci (PULs) complexes enable bacteria to bind, break down, and import specific polysaccharides, contributing to successful gut colonization. A new study explores how PULs are regulated post-transcriptionally to adapt to environmental changes.

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.
-
NewsAgricultural scientists call for removal of more than 120 ‘phantom agents’ from pathogen regulatory lists
Wiping “phantom agents” from a list of suspected plant pathogens would improve agricultural efficiency and food security by updating regulations on international shipment of pathogen-free plant materials destined for countries where they are needed.

NewsStudy shows head trauma may activate latent viruses, leading to neurodegeneration
Researchers have uncovered mechanisms that may connect the dots between trauma and the emergence of disease, pointing to latent viruses lurking in most of our brains that may be activated by the jolt, leading to inflammation and accumulating damage.

NewsAs prevention strategy for sexually transmitted infections rolls out, experts highlight both promise and knowledge gaps
Real-world evidence demonstrates that the postexposure strategy of doxy PEP is reducing the rate of syphilis and chlamydia, but has had little to no effect on gonorrhea and needs close monitoring for signals of antibiotic resistance.
-
NewsNew study shows plummeting STIs with doxyPEP use
A new study has found that rates of chlamydia and syphilis plummet among people prescribed doxycycline for sexually transmitted infection prevention in routine clinical care.

NewsStudy traces Ebola’s route to the skin surface
Researchers have traced a cellular route the Ebola virus uses to traverse the inner and outer layers of skin and emerge onto the skin’s surface. The study identifies new cell types within the skin that are targeted by EBOV during infection.
