A steady supply of its favorite food helps a deadly bacterium thrive in the lungs of people with cystic fibrosis, according to a new study by Columbia researchers.
A new Northwestern University study discovered that spaceflight -- both aboard a space shuttle or the International Space Station (ISS) -- has a consistent effect on the gut microbiome.
A globally important ocean algae is mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new paper. A massive dataset has revealed patterns in the regions where Atlantic coccolithophores live, illuminating the inner workings of the ocean carbon cycle and raising new questions.
The lab of Cheryl Kerfeld at Michigan State University has created a synthetic nano-sized factory, based on natural ones found in bacteria. This research could someday lead to new medical, industrial or bioenergy applications.
More than one-fifth of all human cancers harbor mutations in one of the members of the BAF chromatin remodeling complex. Deep biochemical and epigenomic characterization of a cell line panel comprehensively representing all these mutations enabled researchers at the CeMM Research Center for Molecule Medicine of the Austrian Academy of Sciences to identify new approaches to target BAF mutant cancers. The study describing these findings has now been published in the journal Nature Genetics.
A new DNA test to detect chlamydia infection in koalas which gives on-the-spot results within 30 minutes has been developed in a collaboration between researchers in Brisbane, Australia.
The U.S. Preventive Services Task Force offers new guidelines on BRCA1/2 genetic testing. Susan Domchek, MD, writes in JAMA that there is more the medical community should be doing to connect at-risk patients with the most thorough and helpful genetic information.
Poo transplants are helping expand koala microbiomes, allowing the marsupials to eat a wider range of eucalypts and possibly survive habitat loss. A study featuring University of Queensland researchers has analysed and altered microbes in koalas' guts, finding that a faecal transplant may influence what species of eucalypt koalas can feed on.
The tiny organisms cling to oil droplets and perform a great feat: As a single organism, they may produce methane from oil by a process called alkane disproportionation. Previously this was only known from symbioses between bacteria and archaea. Scientists from the Max Planck Institute for Marine Microbiology have now found cells of this microbe called Methanoliparia in oil reservoirs worldwide.
Most types of Escherichia coli are harmless, but the ones that aren't can cause severe life-threatening diarrhea. These problematic bacteria launch infections by inducing intestinal cells to form tiny structures, called pedestals, that anchor the pathogens in place and help the colonies grow.
