Once upon a time, Earth was barren.

A 2.4-billion-year old microfossil found in the Pilbara's Hamersley Ranges could be a missing link in the evolution from simple to complex life, according to researchers.

Researchers found differences in the gut microbes of autistic people, raising hopes for faster diagnosis

Peering into the jungle of microbes that live within us, researchers have stumbled across what seem to be an entire new class of virus-like objects.

The unbearable itch that accompanies the chronic inflammatory skin condition eczema has a new culprit.

Researchers are desperately seeking viable alternatives to antibiotics. So what is phage therapy? And how could it help?

With the help of the microbes that once played an essential role in keeping you alive, the building blocks of your body go on to become a part of other living things.

When Italian explorer Christopher Columbus and his Spanish troops returned to Europe from the Americas in the late 15th century, they notoriously brought back the deadly pathogen responsible for syphilis.

There are myths about the whole world inside your gut, made up of mostly harmless and often helpful microbes that reside in the gastrointestinal tract.

Bacteriophages have been a mainstay in medical centers abroad for some time now. Georgia’s Eliava Institute has been active since the 1930s. Yet countries including the U.S. and U.K. grant access almost exclusively under compassionate use. That means bacteriophages have been languishing for decades as a last-ditch option.

Modified viruses have proven a handy way to get CRISPR/Cas9 gene editing materials into the nucleus of cells – but they're expensive, difficult to scale and potentially toxic. Now, researchers have found a non-viral approach that does the job better.

Scientists at the University of Helsinki on Friday said they had demonstrated that certain strains of Desulfovibrio bacteria are probable causes (siirryt toiseen palveluun) of Parkinson's disease in most cases. This finding enables screening carriers of Desulfovibrio strains and subsequently removing the bacteria from the gut. This may make it possible to prevent Parkinson's disease.

In the deep waters of Earth's oceans, scientists have discovered a new species of bacteria flourishing in the plumes from submarine hot springs. Such hot springs likely also exist on oceanic worlds like Jupiter's moon Europa and the Saturn satellite Enceladus, so these observations sharpen our understanding of the forms alien life might take on those moons, astronomers say.

Pathogens such as E coli, norovirus and salmonella can be blown miles into coastal communities after a rainstorm

Parkinson's disease may start in the gut and spread to the brain, a new study from the University of Surrey suggests.

Many microscopy techniques have won Nobel Prizes over the years. Advancements like cryo-ET that allow scientists to see the individual atoms of cells can reveal their biological functions.

To preserve humankind’s diverse bacteria, scientists are harvesting, freezing, and storing poop from around the world.

A new study has analyzed the microbiome of a species of coral before, during and after a period of “dormancy” during cold temperatures. The research found that Astrangia poculata's microbiome "reshuffles" during a period of quiescence.

A team of researchers affiliated with multiple institutions in China, working with a colleague in the U.S., has isolated a type of bacteria in the guts of mice that break down nicotine. In their paper published in the journal Nature, the group describes how they isolated the bacteria and why their finding could reduce incidences of fatty liver disease in humans.

A vaccine tablet that dissolves under the tongue protects against urinary tract infections (UTIs) in mice and rabbits. If it is shown to work in people, it could reduce the need to treat these infections with antibiotics.
