The fossilized trail of an aquatic creature suggests that animals walked using legs at least 30 million years earlier than had been thought. The tracks — two parallel rows of small dots, each about 2 millimeters in diameter — date back some 570 million years, to the Ediacaran period.

Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially making it resistant to being killed by some [...]

Aphids (plant lice) and ants carry minibacteria that produce essential amino acids and vitamins. These minibacteria have very limited genetic material and many broken genes. Now, researchers have found that repeated errors in the conversion of DNA to protein save the function of the damaged genes.
