NewsUnraveling cell death protein may inspire new biotechnology tool
Scientists have unraveled the step-by-step activation process of a protein with a deep evolutionary history in all domains of life, opening the door to harnessing its functions for use as a biotechnology tool. The protein belongs to the ‘superfamily’ of Argonaute proteins, which previous research has suggested ...

NewsScientists develop new solid-state storage method for biological materials
Scientists have developed a novel method for storing biological materials such as RNA and proteins in a solid-state, physically resembling a pill or a tablet, which dissolves in water for on-demand use.

NewsEavesdropping viruses wait for bacterial signals before switching to kill mode
Researchers have found that dozens of viruses respond to quorum sensing or other chemical signals from bacteria.

NewsMenstrual cups can help prevent infection and boost vaginal health
Teenage girls who were given menstrual cups were less likely to acquire certain kinds of vaginal infections and were more likely to have a healthy vaginal microbiome, a study has found.

NewsSoil microbes help plants cope with drought, but not how scientists thought
Researchers have found microbes help plants cope with drought, but not in response to plants’ cries for help - instead, the environment itself selects for drought-tolerant microbes.

NewsBiosurfactants may offer green solution for tackling oil spills
Researchers investigating whether biosurfactants could increase microbiological oil degradation in North Sea seawater say there is potential for a more effective and environmentally friendly oil spill response.

NewsProbiotic combo stops bacteria that cause toxic shock syndrome
A probiotic combination could reduce incidence of toxic shock syndrome, a rapid-onset, life-threatening disease associated with strains of Staphylococcus aureus.

NewsFly toolkit created for investigating COVID-19 infection mechanisms
A new ‘fly-to-bedside’ resource offers a shortcut for developing drug therapies needed for long COVID and future coronavirus outbreaks.

NewsWormlike animals are first amphibians shown to pass microbes to their offspring
Skin-feeding does more than provide nutrients for young caecilians - it also helps the mother pass microbes from her skin and gut down to her young, inoculating them to jump-start a healthy microbiome.

NewsMolecular biologists identify framework for understanding RNA editing in a disease-causing parasite
Researchers have determined the architecture of the molecular machines that harbour gRNA strands and allow those strands to engage mRNA in the single-celled, disease-causing parasite Trypanosoma brucei.

NewsResearchers use mass spectrometry to explore antimicrobial resistance
Researchers are using single-cell mass spectrometry to determine whether cells with persistent pathogens will also have less intracellular drug levels to potentially explain antimicrobial treatment failure.

NewsResearchers uncover novel bacterial communication system to combat AMR
Using a sophisticated mass spectrometry technology developed at SMART and MIT, researchers have discovered that the enzyme RlmN is a stress sensor for reactive oxygen species (ROS) – highly reactive molecules which can cause damage to bacteria. Source: SMART AMR (L to R) SMART researchers Dr Cui Liang, ...

NewsBioluminescent bacteria coordinate signalling to colonize squid’s light organ
Researchers reveal how bioluminescent bacteria coordinate their behaviour to colonize the Hawaiian bobtail squid through cellular signaling and cues from the environment.
-
NewsBacterial protein may contribute to reduced fertility and birth defects
Scientists have published new findings that emphasize the crucial role of the urinary and genital tract microbiota in adverse pregnancy outcomes and genomic instability that originate in the womb during foetal development.

NewsResearchers craft ‘origami DNA’ to control virus assembly
Researchers have used DNA ‘origami’ templates to control the way viruses are assembled. The global team behind the research, published in Nature Nanotechnology, developed a way to direct the assembly of virus capsids – the protein shell of viruses - at physiological conditions in a precise and programmable manner. ...
