A NASA scientist has discovered a new species of organism that thrives in a salty, alkaline environment without oxygen. The Spirochaeta americana microorganism can survive in conditions inhospitable to humans and is of great interest to astrobiologists studying the possibility of life on Mars.
Researchers have found that a species of micro-organism, Sulfolobus, has genetic differences between samples from the US, Eastern Russia, and Iceland. This challenges the long-held view that micro-organisms do not differ by geographic location.
A new study suggests that horizontal gene transfer occurs in flowering plants for thousands of ordinary genes, contradicting the traditional view that eukaryotes acquire genes only through vertical transmission. The research found anomalous genetic material in mitochondrial DNA chromosomes across different species.
Bacteria are a crucial component of Earth's biodiversity. Increasing primary productivity in experimental ponds results in changes to the number and types of bacteria present, with differences observed across various taxonomic groups.
A study by Tufts University biologists found that female fireflies are attracted to males with longer flashes, indicating they can be better fathers. The length of a male's flash is related to the quality and quantity of his 'nuptial gift', which provides essential nutrition for his offspring.
A recent study by Max Planck Institute researchers found that in mutualistic interactions between species, the faster-evolving species may actually lose out. The slow-moving species can gain an advantage when both are generous and coordinate their strategies, whereas quickly evolving species tend to adapt to slow evolvers' needs.
Researchers propose that Oxygen-making microbes came later, around 100 million years after the emergence of Sulfur-loving bacteria. This revised evolutionary history may explain the lack of cyanobacteria fossils in ancient iron formations and resolve biochemical contradictions.
Scientists have found tiny bugs living inside mealybugs, which could aid in pest control efforts. The discovery also reveals a complex relationship between the insects and their bacteria, potentially leading to new methods of species identification.
Researchers at the University of Illinois at Urbana-Champaign have identified the main bacteria associated with black band disease, a widespread coral disease characterized by a ring-shaped bacterial mat. The study found that cyanobacteria are a key factor in the development of the disease.
The UMass microbiology team found that Geobacter metallireducens has a built-in sensor to locate metals and can grow flagella to swim towards them. The bacteria use these strategies to survive in natural environments, and their genome revealed genes for flagella growth, allowing them to transform metal into an insoluble form.
Researchers found bacterial proteins cause autoimmune disorders in APS patients by mimicking endogenous host proteins. High-affinity antibodies against these proteins were pathogenic and induced symptoms similar to APS. The study raises concerns about vaccine risks, particularly the tetanus toxoid protein.
Researchers at Princeton University have identified a key signaling molecule, AI2, that allows certain bacteria to perform functions only when part of a sufficiently dense population. The molecule contains boron and has significant implications for the development of new antibiotics.
Cystic fibrosis (CF) patients are more susceptible to Pseudomonas aeruginosa infections due to hypoxic mucus. Hypoxia disrupts the natural antimicrobial properties of mucus, creating an ideal environment for bacterial growth.
A potent bacterial toxin called streptolysin S (SLS) plays a crucial role in producing necrotizing fasciitis, a severe infection also known as 'flesh-eating disease'. Researchers discovered that SLS is essential for both group A Streptococcus and group G Streptococcus bacteria to cause the infection.
Scientists discovered a bacteria, Clostridium novyi, that thrives in oxygen-poor environments and destroys tumor cells. In mouse models, the bacteria was combined with chemotherapy to achieve dramatic results, completely destroying over half of the treated tumors within 24 hours.
A bacterial peptide has been identified as a key regulator of host responses to infection. This discovery opens up new avenues for the development of therapies targeting this process.
Researchers found that light reacts with iron-bound siderophores, making iron more available to marine bacteria. This process has significant implications for the ocean's iron cycle and carbon sequestration.
Researchers found that bacteria in desert soil migrate towards water, not just light, and return to subsurface after drying out. This discovery has significant implications for understanding underground microbial ecology and potentially locating life on Mars.
Researchers found that newly restored wetlands often struggle with invasive weeds, which can outcompete native species for resources. The cost of wetland restoration is also a significant barrier, with some projects costing up to $200,000 per hectare.
A team of researchers has discovered a diverse range of actinomycetes in marine environments, including coral reef sponges and sediments. These bacteria have the potential to produce novel antibiotics and are being explored as a source of future medicines.
A team of biologists led by Carl E. Bauer have determined that non-oxygen-producing bacterial species such as purple and green bacteria are the most ancient photosynthetic bacteria. This finding reverses conventional thinking on the evolution of photosynthetic bacteria, suggesting a complex evolutionary history.
Researchers at the University of Washington found a strong correlation between the diversity of plants, algae, and bacteria in an ecosystem. The study suggests that altering biodiversity can have far-reaching effects on the entire food chain.
Researchers found that digital exams nearly doubled vaginal bacteria entering the cervix and uterus in 80% of patients. Potentially harmful bacteria like Group B Streptococcus and E. coli were isolated from cultures, posing a risk to newborns.
The vaccine targets Escherichia coli, the bacterium causing 85% of UTIs. Recipients develop antibodies that prevent bacteria from colonizing bladder walls. Clinical trials in women are planned for the end of this year to test the vaccine's effectiveness.
Using advanced molecular methods, researchers at Harvard Medical School are identifying mysterious bacterial species that may be the cause of dental root caries and periodontitis. The team is also working on an integrated system for bacterial identification that can be used in various applications.
A study published by University of Georgia researchers reveals a vast array of novel bacteria in Carolina bays, many of which remain unclassified. The discovery highlights the importance of the microbial world in shaping biodiversity.
