NewsSelf-decontaminating fabric burns out viruses but is safe for skin
A new material that packs deadly heat for viruses on its outer surface while staying cool on the reverse side could transform the way we make and use personal protective equipment (PPE).
-
NewsMalaria parasites resistant to treatment and detection emerge in Ethiopia
Genomic surveillance by scientists has revealed mutations in malaria-causing parasites that will complicate efforts to eradicate the disease in Africa.

NewsStudy reveals how leishmaniasis vaccines work at molecular level
Researchers have determined how these vaccine candidates for leishmaniasis prompt molecular-level changes in host cells that have specific roles in helping generate the immune response.
-
NewsMap the coronavirus spike protein for insight into vaccine development
A new study has found that the fusion peptide in the spike protein plays a more invasive role in fusing the virus to the cell than previously thought, which is significant in understanding how infection occurs.
