Can bacteria survive in space?

Can bacteria survive in space? Earth microbes could be contaminating different planets. Notwithstanding extraordinary purification endeavors, microorganisms from Earth still figures out how to discover its way into space on board shuttle. Scientists are working to better understand  how and why a few spores elude decontamination. The research was based on spore-forming microscopic organisms, which can survive harsh environments   on earth. These microscopic organisms could hitch a ride on shuttles and contaminate other planets, making the chase for alien   life forms difficult. Microscopic organisms taken from the scrumptiously named fishing village of Beer on Britain's south coast have demonstrated themselves some of the hardiest creatures on Earth - or in space so far as that is concerned. Microorganisms found in rocks taken from the cliffs at Beer have survived an exhausting 18 months introduction to space conditions on the outside of the ISS and returned home al

Microbiology of the rapidly changing polar environments

Microbiology of the rapidly changing polar environments Marine and freshwater polar environments are characterized by intense physical forces and strong seasonal variations. The persistent cold and sometimes inhospitable conditions create unique ecosystems and habitats for microbial life. Polar microbial communities are diverse productive assemblages, which drive biogeochemical cycles and support higher food-webs across the Arctic and over much of the Antarctic. Recent studies on the biogeography of microbial species have revealed phylogenetically diverse polar ecotypes, suggesting adaptation to seasonal darkness, sea-ice coverage and high summer irradiance. Because of the diversity of habitats related to oceanic circulation and the formation and melting of sea ice, high latitude oceans are ideal environments to investigate composition and functionality of marine microbes. In addition, polar regions are responding more dramatically to climate change compared to temperate environ

Microbes on the skin promote Tissue healing and Immunity

Useful microscopic organisms on the skin of lab mice work with the animals' immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research. Researchers say untangling similar mechanisms in humans may improve approaches to managing skin wounds and treating other damaged tissues.. Like humans and different warm blooded animals, mice are inhabited by large, diverse microbial populations collectively called the microbiome . While the microbiome is believed to have numerous useful functions over a few organ frameworks, little is thought about how the insusceptible framework reacts to these harmless microscopic organisms. To research, NIAID researchers drove by Yasmine Belkaid, Ph.D., head of the Mucosal Immunology Section of NIAID's Laboratory of Parasitic Diseases, observed the reaction of mouse immune cells to Staphylococcus epidermidis, a bacterium frequently found on human skin that does not regularly cause malady.

Bioluminescent Bacteria in a Wifi Pill Track Gut Health in Pigs

Bioengineers have thought of a pill containing bioengineered bacteria and hardware that can read and  wirelessly transmit data as a methods for checking gut health. The model of this ingestible-smaller scale bio-electronic (IMBED) case was utilized to spot intestinal bleeding in pigs . "We could advance these living frameworks to possibly detect any biological marker," Mark Mimee, a graduate understudy at MIT and lead creator of the examination, reveals to STAT News. The essential thought of Mimee's pill is that microorganisms shine within the sight of a specific atom, and a contiguous electronic circuit recognizes the light signal and wirelessly transmits it to a cell phone. For this evidence of-idea show, Mimee and his partners designed E. coli to bioluminescence when they experience the compound heme, a marker of bleeding, in the guts of pigs. Bundled inside a capsule 1.5 inches long, the microorganisms and hardware cautioned the specialists to seeping
