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.

NewsMarine heatwaves have hidden impacts on ocean food webs and carbon cycling
A new study analyzing data from robotic floats and plankton records reveals how marine heatwaves reshape ocean food webs and slow transport of carbon to the deep sea.

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.

NewsThe essential role of the urban tree microbiome: A key to city health
Researchers studied the difference in microbial communities of street trees and non-urban forest trees. By analyzing fungal and bacterial diversity, tree size, and soil properties, their research shows the impacts of urban environmental stressors upon city tree microbiomes.

NewsLong Ebola: Sudan virus can persist in survivors for months, study shows
More than half of survivors of the Sudan Ebola virus still suffer serious health problems two years post-infection and the virus can persist in semen and breast milk for months after recovery, according to the first study examining the virus’s long-term effects.
