Site author Richard Steane The BioTopics website gives access to interactive resource material, developed to support the learning and teaching of Biology at a variety of levels. The Structure of bacterial cells Use the mouse to label these diagrams of a bacterial cell. Labels should include the following - but also read the notes which follow. single chromosome…
Photo by: icholakov Hundreds of thousands of bacterial species exist on Earth. They can be found in very diverse environments ranging from cold to hot and alkaline to acid. They live in soil, in water, and on rocks. They exist deep in the earth, high on mountains, and in deep-sea vents. They grow on and in other bacteria, worms, insects, plants, animals, and…
EMBL discovery could yield evolutionary insights and new model organism This electron microscopy image shows Gemmata obscuriglobus . This and other PVC bacteria, the EMBL scientists discovered, have membrane-coat proteins associated with the membranes of subcellular compartments like the one shown in green, in which vesicles can be seen as dark green regions…
The chaotic movements of bacteria could be tamed to create electricity, powering miniature future gadgets, such as medical devices or other nanoscale machines. A newly published paper from researchers at Oxford University explains how to turn a fluid soup of bacteria into a kind of miniature wind farm. The team dropped a minuscule array of 64 rotors into a microfluid…
Most healthy vaginas have yeast. But sometimes your yeast grows too much and leads to an infection. Yeast infections can be very irritating and uncomfortable. What causes yeast infections? A vaginal yeast infection, which is also sometimes called vulvovaginal candidiasis, happens when the healthy yeast that normally lives in your vagina grows out of control…
