A team from Harvard University, Marine Biological Laboratory, and collaborators show how the rod-shaped bacteria Bacillus subtilis maintains its precise diameter while growing end to end.
The caterpillars of Lymantria dispar or Gypsy Moth are voracious eaters capable of defoliating entire forests. Sometimes they can even make harm for coniferous forests. Gypsy Moths are widely spread in Europe, Asia and Northern America.
Scientists from the University of Adelaide's Research Centre for Infectious Diseases have developed a single vaccination approach to simultaneously combat influenza and pneumococcal infections, the world's most deadly respiratory diseases.
In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks. Addressing the problem in Frontiers in Earth Science, Swedish scientists have begun compiling evidence of fossilized microbes in underexplored igneous rock environments on Earth, to help guide where to search for a Martian fossil record - and what to look for.
Recent research led by Assistant Professor Fumio Motegi, Principal Investigator at the Mechanobiology Institute at the National University of Singapore, has identified the master switch that triggers the symmetry breaking process in the zygotes of the nematode worm, Caenorhabditis elegans.
Salmonella, genetically modified foods and microplastics in food head the awareness scale of health and consumer topics in Germany. Despite this, more than three quarters of Germans regard food as safe. This is the result of the latest Consumer Monitor -- a representative population survey carried out by the German Federal Institute for Risk Assessment (BfR). Most people are concerned about antimicrobial resistance, microplastics and residues of plant protection products in food.
An open-source RNA analysis platform has been successfully used on plant cells for the first time -- a breakthrough that could herald a new era of fundamental research and bolster efforts to engineer more efficient food and biofuel crops. The technology, called Drop-seq is a method for measuring the RNA present in individual cells, allowing scientists to see what genes are being expressed and how this relates to the specific functions of different cell types.
Researchers at The University of Chicago have demonstrated that the type of bacteria living in the gut can influence the development of Alzheimer's disease symptoms in mice. The study, which will be published May 16, 2019 in the Journal of Experimental Medicine, shows that, by altering the gut microbiome, long-term antibiotic treatment reduces inflammation and slows the growth of amyloid plaques in the brains of male mice, though the same treatment has no effect on female animals.
In a new hypothesis, a CRC 1182 research team suggests that inflammatory diseases are caused by an over-supply of food, and the associated disturbance of the intestine's natural bacterial colonisation.
A recent study by researchers at University of California San Diego School of Medicine, San Diego State University and the Max Planck Institute for Developmental Biology found that the age and sex of an individual strongly influences the bacterial diversity of the gut microbiome.
