The culprit is what has now been named Klebsiella aerogenes, the McMaster-Queen (MQ) strain, identified in up to 25 per cent of gut microbiota samples from patients with IBS. Researchers examined stool microbiota samples from both Canadian and American patient cohorts.

A new study suggests that the link between bats and coronaviruses is likely due to a long-shared history, and that their genetic information can help us prevent and manage future pandemics.

Researchers have developed a technique to control pH at the local level, creating a dense array of microsites where the amount of protons is 100 to 1000 times higher than the average in the rest of the solution.

A newly identified 16th century horse specimen is among the oldest domestic horses from the Americas known to date, and its DNA helps clarify the history of horses in the Western Hemisphere, according to a new study.

Beaver fur was a symbol of wealth and an important trade item in 10th Century Denmark, according to a new study.

The damaging effects of daily, lifelong exposure to the blue light emanating from phones, computers and household fixtures worsen as a person ages, new research suggests. The study involved Drosophila melanogaster, the common fruit fly, an important model organism because of the cellular and developmental mechanisms it shares with other animals and humans.

From immunity to metabolism to mental health, it seems like the gut microbiome has been linked to every aspect of human health and disease. But with hundreds of bacterial species populating our gastrointestinal tract, it's a daunting task to pinpoint which molecules made by which bacteria affect which biological processes -- and how they do so.

Prehistoric people in Europe were consuming milk thousands of years before humans evolved the genetic trait allowing us to digest the milk sugar lactose as adults, finds a new study.

An international team of researchers has developed a method for altering one class of antibiotics, using microscopic organisms that produce these compounds naturally.

Researchers from Leipzig published a gigantic digital map displaying the full diversity of life through thousands of photos. The so-called LifeGate encompasses all 2.6 million known species of this planet and shows their relationship to each other.
