NewsExposure to Mycobacterium seems to remodel immune response against TB
A collaborative team has uncovered how prior exposure to bacteria changes the lung’s innate immune response - and what it might mean for vaccines.
-
NewsSARS-CoV-2 can infect dopamine neurons, causing senescence
A new study has reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence - when a cell loses the ability to grow and divide.

NewsHIV antibodies protect animals in proof-of-concept study
Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people.
-
NewsNew study to examine very rare adverse events linked to COVID-19 vaccines
A multimillion-dollar global initiative will study causes and risk factors, to ensure safer vaccines are ready for the next potential pandemic.
-
NewsAnti-HIV drugs may prevent complications from bacterial sepsis
A new study suggests that reverse transcriptase inhibitors — antiretroviral drugs also used to manage HIV infections — can be used to prevent inflammatory complications of bacterial sepsis.
-
NewsVaccine speeds up the production of antibodies against Covid
A new vaccine uses preexisting immunity to a separate virus (the influenza virus) to help kickstart the process of making antibodies against SARS-CoV-2.
-
NewsMicrobe-powered fuel cell runs forever
Researchers have developed a new fuel cell that harvests energy from microbes living in soil.
-
NewsNonpharmaceutical interventions saved lives during COVID’s first wave, study shows
Research reveals that masking, shelter-in-place and other measures reduced growth rates of deaths, case numbers and hospitalizations in early 2020.
-
NewsResearch reveals why staph vaccine candidates keep failing - and how to fix the problem
Research from UC San Diego explains the clinical failure of dozens of candidate vaccines for one of the most common human infections; it also suggests a way to fix the problem.

NewsCOVID-19 vaccine reduces long COVID in children
Researchers have found that vaccination of children provides moderate protection against long COVID. Vaccination also has a stronger effect in adolescents, who have a higher risk of developing long COVID than young children.

NewsA single-celled microbe is helping corals survive climate change
Researchers have discovered a single-celled microbe that can help corals survive ocean-warming events like bleaching.
-
NewsScientists deliver new insights into what helps Salmonella cause infections
Researchers have discovered how a system of proteins, called TamAB, helps Salmonella survive under the harsh conditions inside macrophages.
