A Washington University team showed how a phototrophic microbe called Rhodopseudomonas palustris takes up electrons from conductive substances like metal oxides or rust to reduce carbon dioxide.
Current treatments for tuberculosis (TB) are very effective in controlling TB infection caused by Mycobacterium tuberculosis (Mtb). They don't, however, always prevent reinfection. Why this happens is one of the long-standing questions in TB research. A team of scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University may have found the answer... in the gut.
In a surprising finding, researchers at the University of Michigan Rogel Cancer Center showed the protein NLRP6 aggravated the difficult symptoms of gastrointestinal graft-vs.-host disease. Knocking out this protein in mice led to significantly better survival and less severe GVHD.
Leaf-feeding caterpillars greatly enrich their intestinal flora by eating soil. It's even possible to trace the legacy effects of plants that previously grew in that soil through bacteria and fungi in the caterpillars. Researchers of the Netherlands Institute of Ecology (NIOO-KNAW) have just published these findings in the journal Nature Communications. They are of interest not just to scientists, but also to plant growers and farmers.
A new study by UAlberta biologists shows the first evidence of apoptosis, or programmed cell death in algae. The outcomes have broad-reaching implications, from the development of targeted antibiotics to the production of biofuels in industry.
Spontaneous preterm birth (sPTB), defined as birth before 37 weeks of gestation, and the related complications, are the largest contributors to infant death in the United States and worldwide, according to the World Health Organization. Researchers at the University of Maryland School of Medicine (UMSOM) have discovered that bacteria and innate immune factors in a woman's birth canal and cervix may increase the risk of spontaneous preterm birth or provide protection against such births.
A researcher in the Vera Bradley Foundation Center for Breast Cancer Research at the Indiana University School of Medicine, working in collaboration with researchers from the University of Maryland, recently reported several important findings related to triple negative breast cancer and its future treatment in the journal Nature Nanotechnology.
In a front-cover paper published in Cerebral Cortex, EPFL's Blue Brain Project, a Swiss Brain Research Initiative, explains how the shapes of neurons can be classified using mathematical methods from the field of algebraic topology. Neuroscientists can now start building a formal catalogue for all the types of cells in the brain. Onto this catalogue of cells, they can systematically map the function and role in disease of each type of neuron in the brain.
Superbugs, also known as Gram-negative bacteria, are causing a global health crisis. To combat antibiotic-resistant infections, researchers are pursuing clever new ways to thwart the bacteria's tough defense system. Now, they have uncovered some of the previously unknown machinery that builds the bacterial outer membrane, information that could lead to new treatments for untreatable infections.
The creation of new library of mutants of the single-celled photosynthetic green alga, Chlamydomonas reinhardtii enabled a Carnegie- and Princeton University-led team of plant scientists to identify more than 300 genes that are potentially required for photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert energy from sunlight into carbohydrates -- filling our planet's atmosphere with oxygen as a byproduct.
