Complex building blocks of life form spontaneously in space, research reveals

Challenging long-held assumptions, Aarhus University researchers have demonstrated that the protein building blocks essential for life as we know it can form readily in space. This discovery, appearing in Nature Astronomy, significantly raises the statistical probability of finding extraterrestrial life.

Experiments bring Enceladus' subsurface ocean into the lab

Through new experiments, researchers in Japan and Germany have recreated the chemical conditions found in the subsurface ocean of Saturn's moon, Enceladus. Published in Icarus, the results show that these conditions can readily produce many of the organic compounds observed by the Cassini mission, strengthening evidence that the distant world could harbor the molecular building blocks of life.

Golden Gate method enables fully-synthetic engineering of therapeutically relevant bacteriophages

Bacteriophages have been used therapeutically to treat infectious bacterial diseases for over a century. As antibiotic-resistant infections increasingly threaten public health, interest in bacteriophages as therapeutics has seen a resurgence. However, the field remains largely limited to naturally occurring strains, as laborious strain engineering techniques have limited the pace of discovery and the creation of tailored therapeutic strains.

An unusually 'sticky' RNA class that keep cells organized: Researchers discover smOOPs

Inside cells, RNAs and proteins form tiny, liquid-like droplets called biomolecular condensates. These droplets are essential for organizing cellular life, yet why some RNAs cluster more readily than others has remained unclear. Disruptions in condensate formation are linked to developmental defects, cancer, and neurodegenerative diseases.

How light suppresses virulence in an antibiotic-resistant pathogen

Light is a universal stimulus that influences all living things. Cycles of light and dark help set the biological clocks for organisms ranging from single-celled bacteria to human beings. Some bacteria use photosynthesis to convert sunlight into energy just like plants, but other bacteria sense light for less well-known functions.

Immunogenicity of DNA, mRNA and Subunit Vaccines Against Beak and Feather Disease Virus

Background/Objectives: Beak and feather disease virus (BFDV) is the causative agent of psittacine beak and feather disease (PBFD), affecting psittacine birds. There is currently no commercial vaccine or treatment for this disease. This study developed a novel BFDV coat protein mRNA vaccine encapsidated by TMV coat protein to form pseudovirions (PsVs) and tested its immunogenicity alongside BFDV coat protein (CP) subunit and DNA vaccine candidates. Methods: mRNA and BFDV CP subunit vaccine candidates were produced in Nicotiana benthamiana and subsequently purified using PEG precipitation and gradient ultracentrifugation, respectively. The DNA vaccine candidate was produced in E. coli cells harbouring a plasmid with a BFDV1.1mer pseudogenome. Immunogenicity of the vaccine candidates was evaluated in African grey parrot chicks. Results: Successful purification of TMV PsVs harbouring the mRNA vaccine, and of the BFDV-CP subunit vaccine, was confirmed by SDS-PAGE and western blot analysis. TEM analyses confirmed formation of TMV PsVs, while RT-PCR and RT-qPCR cDNA amplification confirmed encapsidation of the mRNA vaccine candidate within TMV particles. Restriction digests verified presence of the BFDV1.1mer genome in the plasmid. Four groups of 5 ten-week-old African grey parrot (Psittacus erithacus) chicks were vaccinated and received two boost vaccinations 2 weeks apart. Blood samples were collected from all four groups on day 14, 28 and 42, and sera were analysed using indirect ELISA, which showed that all vaccine candidates successfully elicited specific anti-BFDV-CP immune responses. The subunit vaccine candidate showed the strongest immune response, indicated by higher binding titres (>6400), followed by the mRNA and DNA vaccine candidates. Conclusions: The candidate vaccines present an important milestone in the search for a protective vaccine against PBFD, and their inexpensive manufacture could considerably aid commercial vaccine development.
