15-05-22 It's no wonder that giant pandas are always chewing and eating, say Chinese researchers: their gut bacteria are not the type for efficiently digesting bamboo. The bamboo-eating giant panda actually harbors a carnivore-like gut microbiota predominate...

15-05-15 Researchers studying a dangerous type of bacteria have discovered that the bacteria have the ability to block both their own growth and the growth of their antibiotic-resistant mutants. The discovery might lead to better ways to fight a class of bac...

15-04-14 It may come as a bit of a surprise to learn that bacteria have an immune system -- in their case to fight off invasive viruses called phages. And like any immune system -- from single-celled to human -- the first challenge of the bacterial immune sy...

15-04-13 Although serotonin is well known as a brain neurotransmitter, it is estimated that 90 percent of the body's serotonin is made in the digestive tract. In fact, altered levels of this peripheral serotonin have been linked to diseases such as irritable...

15-03-30 New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to work published in journal Science on 27 March, the bacteria can load electrons onto and discharge electrons from microscopic particle...

15-03-17 The warm soft folds of the intestines are teeming with thousands of species of bacteria. Collectively known as the gut microbiome, these microbes help break down food, synthesize vitamins, regulate weight and resist infection. If they're so key to h...

15-03-13 Bacteria that live on iron were found for the first time at three well-known vent sites along the Mid-Atlantic Ridge, one of the longest undersea mountain ranges in the world. Scientists report that these bacteria likely play an important role in de...

14-12-30 Using mathematical modeling, researchers at New York and Vanderbilt universities have shown that commensal bacteria that cause problems later in life most likely played a key role in stabilizing early human populations. The finding, published in mBi...

14-12-17 Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system -- the first line of defense against disease-causing microbes. In a new study, Yixin Shi, Ph.D., and Wei Kong, Ph.D., re...

14-11-21 近日一项研究发现，一次10秒的深情拥吻不仅传递了爱意，而且还传递了至少8000万的口腔细菌。研究人员表示，法式热吻就是短时间传递大量口腔细菌的绝佳案例。 A single 10-second kiss can transfer as many as 80 million bacteria, according to Dutch scientists. Th...
