13-01-29 In what is believed to be the first study of its kind, researchers used genomic techniques to document the presence of significant numbers of living microorganisms -- principally bacteria -- in the middle and upper troposphere（对流层） , that secti...

13-01-24 It isn't life on Mars, but researchers have found a rich diversity of microbial life and chemicals in the ephemeral（短暂的） habitat of a storm cloud, according to a study published January 23 in the open access journal PLOS ONE by Tina antl Temkiv...

12-12-20 Over the last half decade, it has become increasingly clear that the normal gastrointestinal（胃肠的） (GI) bacteria play a variety of very important roles in the biology of human and animals. Now Vic Norris of the University of Rouen, France, and c...

12-12-10 It's well known how bacteria exposed to antibiotics for long periods will find ways to resist the drugs -- by quickly pumping them out of their cells, for instance, or modifying the compounds so they're no longer toxic. Now new research has uncovere...

12-12-07 The ability to detect rotten food is so crucial for survival that even flies have a dedicated neural circuit to do just that, according to a study published on December 6th in the Cell Press journal Cell. The brain circuit allows flies to avoid feed...

12-11-16 A new study by researchers at Imperial College London has identified a way in which Salmonella bacteria, which cause gastroenteritis（肠胃炎） and typhoid（伤寒） fever, counteract the defence mechanisms of human cells. One way in which our cells fi...

12-10-21 A study has found that nearly one in 10 bank cards contains faecal matter. Cash is little better with one in seven bank notes containing high levels of bacteria similar to that found in a dirty toilet bowl. 一项研究发现，近十分之一的银行卡都携带粪便...

12-09-03 New research published in BioMed Central's open access journal BMC Plant Biology shows how targeting two bacterial genes into an ornamental plant（观赏植物） (Pelargonium), can produce long-lived and pollen-free plants. Pelargoniums ('Geraniums' and...

12-08-31 Bacteria in hyenas' scent glands may be the key controllers of communication. The results, featured in the current issue of Scientific Reports, show a clear relationship between the diversity of hyena clans and the distinct microbial communities tha...

12-08-31 Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science. According to the scientists, more...
