NewsIncrease in cell volume and nuclear number of the Koji fungus enhances enzyme production capacity
This study revealed cellular traits of the koji fungus Aspergillus oryzae linked to enzyme production through cell biological analysis. The authors found that, over time in culture, hyphae thicken, resulting in a tenfold increase in cell volume. Simultaneously, the number of nuclei per hyphal cell also rises tenfold, exceeding 200.

NewsAntibody discovered that blocks almost all known HIV variants in neutralization assays
An international research team has discovered an antibody that could advance the fight against HIV. The newly identified antibody 04_A06 proved to be particularly effective in laboratory tests. It was able to neutralize 98.5 percent of more than 300 different HIV strains, making it one of the broadest antibodies against HIV identified.

NewsResearch reveals fetuses exposed to Zika virus have long-term immune challenges
Researchers discovered that when a pregnant mother is infected with Zika virus, the resulting inflammatory response in the placenta permanently changes how the offspring’s immune system develops - even if the infection is mild or asymptomatic in the mother.
