NewsMicrobial landscape in the early operation phase of China space station
Metagenomics, comparative genomics, and microbial culture techniques were employed to conduct an in-depth analysis of the structure, function, dynamic changes, and adaptation mechanisms of microbial communities within the China Space Station.

NewsProbiotic bacterial strain is more effective for treating a common intestinal infection
Given growing resistance to conventional treatments in the protozoan Giardia intestinalis, researchers are exploring the potential of the probiotic strain Lactobacillus johnsonii CNCM I-4884, patented by INRAE, MNHN and EnvA in 2015.

NewsParasite avoidance study could shed new light on social distancing’s role in disease prevention
New research could shed light on just how important the simple but understudied strategy of social distancing for avoiding disease might be. The work will look at how organisms evolve to avoid parasites.

NewsBacteria-enhanced graphene oxide nanoparticles for triple-action tumor eradication
Researchers developed graphene oxide nanoparticles that combine chemotherapy, immune activation, and photothermal heating to effectively destroy tumors. The novel GO nanocomposite is enhanced with bacterial components.

NewsMushroom study IDs one of the potentially most bitter substances known to date
Researchers have isolated three new bitter compounds from the mushroom Amaropostia stiptica and investigated their effect on human bitter taste receptors.

NewsResearchers discover way to predict treatment success for parasitic skin disease
Researchers have discovered a way to predict whether a patient suffering from cutaneous leishmaniasis will respond to the most common treatment, potentially saving patients from months of expensive, ineffective and toxic medication.

NewsAntimicrobial resistance is a side effect of bacterial clockwork mechanism
Could a gene regulatory network in gut microbes have evolved its elaborate and tightly regulated molecular machinery only to pump out antibiotics indiscriminately? Researchers have shown that this is an auxiliary function.

NewsScientists blame climate change for spread of infectious diseases and unleashing of ice-locked microbes in Arctic
Climate change is creating new pathways for the spread of infectious diseases like brucellosis, tularemia, or E. coli in the Arctic, according to a broad international consortium of scientists.

NewsScientists reveal new bacterial toxin that damages the gut
Scientistshave discovered how a diarrhoea-causing strain of bacteria uses ’molecular scissors’ to cut open and destroy gut cells, leading to severe illness and sometimes death.

NewsNovel point-of-care technology delivers accurate HIV results in minutes
Scientists have developed new technology that could lead to the creation of a rapid point-of-care test for HIV infection competitive with traditional lab-based HIV testing in a fraction of the time and without the need for a stressful wait.
-
NewsResearchers use AI to improve diagnosis of drug-resistant infections
Scientists have developed a new AI-based method that more accurately detects genetic markers of antibiotic resistance in Mycobacterium tuberculosis and Staphylococcus aureus — potentially leading to faster and more effective treatments.

NewsDietary shift after migration increases cardiovascular risk by altering the gut microbiome
An Amsterdam UMC-led study has found that migrants, this case from West Africa to Europe, experience a ‘clear change’ in their microbiome composition as compared to their non-migrant peers in West Africa, which expose them to an increase of cardiovascular disease. These peer-reviewed findings are published in ...

NewsMolecular stool test could improve detection of tuberculosis in adults with HIV
A prospective multicentre study highlights the potential of the Xpert MTB/Ultra stool test for diagnosing tuberculosis in people living with HIV.

NewsHantavirus in Madagascar linked to black rats in agricultural areas
A new study reveals that the black rat is likely responsible for transmitting deadly hantaviruses in rural Madagascar, where forested landscapes have been converted to agriculture and settlements.

NewsMolecules that fight infection also act on the brain, inducing anxiety or sociability
New research on a cytokine called IL-17 adds to growing evidence that immune molecules can influence behavior during illness.
-
NewsThe new season of The Last of Us has a spore-ting chance at realism
The trailer for the hit HBO series appears to show the ’zombie fungus’ cordyceps infecting humans by releasing air-borne spores, instead of through tentacles — closer to scientific reality, according to experts.

NewsResearchers reveal why young plants may be more vulnerable to disease
A new study on baby plants shows that fighting disease at a young age often comes at a steep cost to growth and future evolutionary fitness—or their ability to reproduce.
-
NewsDiscovery of bacteria’s defence against viruses becomes piece of the puzzle against resistance
A new study shows that the emergence of resistance can be understood in the mechanism of how bacteria build up defences against being infected by viruses.
