NewsStaphylococcus aureus thwarts vaccines by turning on a protein that halts immune response
Approximately 30 clinical trials to date have failed to result in an effective human vaccine for Staphylococcus aureus but researchers have now identified a key reason for these failures, indicating that it may be possible to modify the vaccines to work in humans.

NewsA dial for tuning the immune system: Discovery sheds light on why COVID makes some sicker than others
A new study identifies an “immune system tuning dial,” which originated as a bug in the genetic code tens of millions of years ago. When this signaling goes awry and leads the body to under or overreact, people are more likely to develop severe or Long COVID.

NewsGlobal research uncovers critical weakness in malaria parasite
Scientists exploring how immunity develops against Plasmodium falciparum found that broadly reactive antibodies from various individuals consistently bound to the same site on a key virulence protein of the malaria parasite.

NewsResearchers call for global discussion about possible risks from ‘mirror bacteria’
A group of researchers has published new findings on potential risks from the development of mirror bacteria — synthetic organisms in which all molecules have reversed chirality (i.e. are ‘mirrored’).

NewsResearchers uncover how bat-origin pathogenic viruses manipulate human cell death and inflammation
A new study offers insights into cell death regulation by viruses like SARS-CoV-2, and how bats and humans respond differently to tricks that such viruses use to manipulate the host’s defense.
