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.
-
NewsFighting fungal foes: Walnut’s genetic armor against anthracnose revealed
A pivotal study has pinpointed a gene module crucial for enhancing walnut trees’ resistance to anthracnose, a widespread fungal disease threatening the walnut industry.
-
NewsChloroplast manipulation: A new strategy in pathogen warfare uncovered
A cutting-edge study shows how a pathogen’s effector protein circumvents plant defenses, targeting the chloroplast protein StFC-II, increasing its levels in chloroplasts and reducing the plant’s ability to generate reactive oxygen species (ROS).
-
NewsBacterial cells transmit memories to offspring
Bacterial cells can “remember” brief, temporary changes to their bodies and immediate surroundings, a new study has found.
-
NewsLocked in a glacier, viruses adapted to survive extreme weather
Ancient viruses preserved in glacial ice hold valuable information about changes in Earth’s climate, a new study suggests.
-
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.
-
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.
-
NewsNew technology ‘lights up’ bacteria in wounds for better infection prevention
Autofluorescence (AF) imaging uses violet light to illuminate molecules in the cell walls of any bacteria. Different types of bacteria turn different colors, allowing physicians to immediately determine how much and which types of bacteria are in the wound.
-
News3D shapes of viral proteins point to previously unknown roles
Scientists uncover an ancient immune-evading strategy shared by animal viruses and viruses that infect bacteria; findings may help in the development of new antiviral therapies.
-
NewsWhat microscopic fossilized shells tell us about ancient climate change
New research pairs sea surface temperatures with levels of atmospheric CO2 during the end of the Paleocene, showing the two were closely linked.
-
NewsStudy reveals isolation, endogamy and pathogens in early medieval Spanish community
An archaeogenetic study sheds new light on the isolated medieval community Las Gobas in northern Spain. The researchers have identified the variola virus which can offer a new explanation on how smallpox entered Iberia.
