NewsBody lice may be bigger plague spreaders than previously thought
A new laboratory study suggests that human body lice are more efficient at transmitting Yersinia pestis, the bacterium that causes plague, than previously thought, supporting the possibility that they may have contributed to past pandemics.

NewsMatcha mouthwash inhibits bacteria that causes periodontitis
Matcha, a finely ground green tea powder, may help inhibit the growth of Porphyromonas gingivalis, one of the chief bacterial culprits behind periodontitis.

NewsStudy sheds light on bacteria associated with pre-term birth
Researchers have found that multiple species of Gardnerella, bacteria sometimes associated with bacterial vaginosis (BV) and pre-term birth, can coexist in the same vaginal microbiome.

NewsForget the freezer - air-dried soils will still give up their microbial secrets
Scientists have found that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.

NewsResearchers uncover two new mechanisms behind antibiotic resistance
Two newly discovered mechanisms in bacteria have been identified that can contribute to the development of antibiotic resistance. Source: Uppsala University Helen Wang, Senior Lecturer and Docent at the Department of Medical Biochemistry and Microbiology, Uppsala University Changing the number of copies of resistance genes in bacteria ...

NewsScientists unravel the genetic interplay in impatiens downy mildew
A research team has analyzed the transcriptional response of Impatiens walleriana to Plasmopara obducens infection, revealing between 3,000 and 4,500 differentially expressed transcripts at various stages of the disease.

NewsLong-term protection from SARS-CoV-2 variants in mice by a Phase II clinically evaluated original mRNA vaccine booster
A new study discusses the development of an mRNA vaccine (LVRNA009) that encoded the S protein of the Wuhan-Hu-1 strain and evaluated the long-term protection potential against SARS-CoV-2 variants.

NewsGut bacteria boost immune response to fight tumors
Roughly one in five cancer patients benefits from immunotherapy – a treatment that harnesses the immune system to fight cancer. Such an approach to beating cancer has seen significant success in lung cancer and melanoma, among others. Optimistic about its potential, researchers are exploring strategies to improve ...

NewsFrom fungi to fashion: mushroom eco-leather is moving towards the mainstream
As fashion designers look for alternatives to leather, growing mycelium – or fungi-based – ‘leather’ substitutes using a new paste media has opened up the possibility of growing this bio-fabricated material faster, and of cultivating it more easily.

NewsMystery CRISPR unlocked: A new ally against antibiotic resistance?
CRISPR-Cas systems are bacterial adaptive immune systems that target and cut the nucleic acids (DNA/RNA) of invading genetic parasites like bacteriophages (phages); viruses that infect - and eventually kill - bacterial cells. They consist of two main components; the CRISPR array, which stores immune memory of past ...

NewsHuman activity over natural inputs determines the bacterial community in an ice core from the Muztag ata glacier
Scientists nvestigated the bacterial community from a 74 m ice core of Muztag ata glacier on the Tibetan Plateau to link biological indicators with past climate and anthropogenic activities.

NewsScientists harness plant viruses to deliver genome editing reagents in diverse plant species
The use of viral vectors to deliver genome editing components offers potential solutions to many current technical bottlenecks involved in genome editing in plants.

NewsScientists make strides in microbiome-based cancer therapies by iron deprivation at the tumor microenvironment
Researchers have made a significant breakthrough in the fight against cancer, exploring a dietary-derived bacterial strain, IMB001, that induces ’nutritional immunity’ to boost anti-tumor responses.

NewsBreakthrough research identifies mechanism behind drug resistance in malaria parasite
A new study has found that a cellular process called transfer Ribonucleic acid (tRNA) modification influences the malaria parasite’s ability to develop resistance to Artemisinin-based combination therapies.

NewsAI reveals critical gaps in global Antimicrobial Resistance research
Researchers developed global maps showcasing regional, methodological, and sectoral AMR research activities, confirming a lack of interdisciplinary collaboration, particularly in low-income countries, where the burden of increasing AMR is most acute.

NewsResearchers may have come up with second chance for antibiotic agent
A new study focuses on the protein peptide deformylase (PDF), which is involved in protein maturation processes in bacterial cells. While the original drug candidate had to be discarded, modification of the molecule could offer a second chance.

NewsAdvances in priming B cell immunity against HIV pave the way to future HIV vaccines, new studies show
Scientists have made several advances in the design of a class of HIV vaccines that could offer broad protection against the virus, according to four new research papers published this week.

NewsRegenerating worms have genetic control over their algal partners
Researchers have found that when Convolutriloba longifissura, a species of acoel that hosts the symbiotic algae Tetraselmis, regenerates, a genetic factor that takes part in the acoel regeneration also controls how the algae inside of them reacts.
