NewsInternational consortium with NASA reveals hidden impact of spaceflight on gut health
Scientists have uncovered how spaceflight profoundly alters the gut microbiome, revealing previously unknown effects on host physiology that could shape the future of long-duration space missions.

NewsMarine sponge microbe provides insights into the evolution of tuberculosis
The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to the pathogen responsible for tuberculosis (TB) could unlock and inform future TB research and treatment strategies.
-
NewsNew discovery of how bacteria navigate their environment could change how we treat infection
Scientists have found that bacteria can directly measure differences in chemical concentration across the length of their cell bodies, contrary to decades of established scientific belief.

NewsResearch group identifies novel probiotics in traditional Brazilian cheeses
Researchers have identified lactic acid bacteria (LAB) that have probiotic properties and are beneficial to human health in samples of traditional Brazilian cheeses.
-
NewsNew findings on TB could change how we treat inflammatory disorders
Researchers have found rare mutation that leaves its carriers much more likely to become ill with TB—but, curiously, not with other infectious diseases, potentially upending long-held assumptions about the immune system.
-
NewsCOVID-19 vaccination mandates boosted uptake among health care workers
A new study has found that state-level COVID-19 vaccination mandates successfully increased vaccine rates among health care workers, providing evidence that the policy can boost rates even in a highly vaccinated, highly educated population.

NewsImmune protection against tuberculosis reinfection driven by cells that dampen lung inflammation
The body’s first line of defense against tuberculosis (TB) involves immune cells that suppress lung inflammation instead of activating it, scientists report.

NewsSphingomyelins (TFSM) can visualise Chlamydia inclusions within infected human cells
Researchers have succeeded in developing a sphingomyelin derivative that can be used to visualise the distribution of sphingomyelin and the activity of sphingomyelinase in infection processes.

NewsPromising antibiotic candidates discovered in microbes deep in the Arctic Sea
A new study demonstrates that prospecting novel habitats like the Arctic Sea can yield novel antivirulence drugs that are less likely to select for resistance.

NewsClimate change increases foodborne illness risk from raw produce
New research shows that bacterial leaf spot of lettuce and high humidity promote Salmonella enterica growth in lettuce, and climate change is predicted to increase humid periods.

NewsBacteria able to overcome cost of vancomycin resistance in lab setting
Staphylococcus aureus has the potential to develop durable vancomycin resistance, according to a new study.
-
NewsInnovations in cancer treatment through targeted bacterial vaccines
Scientists outline efforts to create an antibacterial vaccine capable of eliciting robust immune responses to selectively eradicate Fusobacterium nucleatum while preserving other microbiota.
-
NewsBacterial cells transmit memories to offspring
Bacterial cells can “remember” brief, temporary changes to their bodies and immediate surroundings, a new study has found.
-
NewsScientists unveil first complete image of the PARIS system
A new study explores the PARIS immune system, which bacteria use to protect themselves against viral infections and which stands for Phage Anti-Restriction Induced System.
-
NewsGut bacteria composition influences rotavirus vaccine efficacy
Gut microbiota can influence rotavirus vaccine responsiveness and sometimes result in children remaining prone to rotavirus infection and severe disease despite having been vaccinated.
-
OpinionDoes getting help for gut health have to be a waiting game?
Gut health issues impact millions of people every day, but how useful are the current UK government measures in improving patient outcomes?

NewsResearchers develop probiotic to ameliorate ulcerative colitis
Researchers have developed a probiotic-based therapeutic that synergistically restores intestinal redox and microbiota homeostasis. It relieved inflammation and reduced colonic damage in mouse and non-human primate (NHP) models of colitis.
-
NewsA human-centered AI tool to improve sepsis management
A proposed artificial intelligence tool to support clinician decision-making about hospital patients at risk for sepsis has an unusual feature: accounting for its lack of certainty and suggesting what data it needs to improve its predictive performance.
-
NewsAI spots cancer and viral infections at nanoscale precision
Scientists have developed an artificial intelligence which can differentiate cancer cells from normal cells, as well as detect the very early stages of viral infection inside cells.

NewsWhat enables herpes simplex virus to become impervious to drugs?
Research pinpoints the key to the cold sore virus’s ability to evade treatment, offering broader clues on antiviral drug resistance.
