Good science anticipates the shortcomings of human intuition; it expects that the concepts so useful for interpreting the world around us, at the familiar human scale, may well prove unsuitable ...
The hook acts as a dynamic joint, transmitting torque from inside the cell to rotate the outer tail, allowing bacteria to move. Disclaimer: AAAS and EurekAlert! are not responsible for the ...
However, some bacterial species have evolved alternative motility mechanisms that allow cells to move on solid surfaces without the aid of flagella; these motility systems are collectively termed ...
Bacteria with flagella, or spinning tails, can move up to a hundred times their body length in a second—a large fish can only move about ten times its body length in a second. The strongest ...
Bacteria are complex single-celled organisms consisting of a cell-wall and an elastic membrane ... The projections on bacteria are known as pili or flagella that help them attach to the host ...
Lab experiments, recently published in Science, show that cyanobacteria — a type of bacteria that produces energy from sunlight through photosynthesis — anticipate the change by bundling up in their ...
Bacteria are protected by the peptidoglycan cell wall, which helps them withstand internal turgor pressure and external damage, such as attacks from other bacteria and viruses. To grow and stay ...
