First detailed microscopy evidence of bacteria at the lower size limit of life

Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn’t been a comprehensive electron microscopy and DNA-based description of the microbes until now. The cells have an average volume of 0.009 cubic microns (one micron is one millionth of a meter). About 150 of these bacteria could fit inside an Escherichia coli cell and more than 150,000 cells could fit onto the tip of a human hair. —> Read More Here

Research of plain wren duets could help further understand fundamentals of conversation

Known for their beautiful singing duets, plain wrens of Costa Rica perform precise phrase-by-phrase modifications to the duration between two consecutive phrases, achieving careful coordination as their songs unfold. A new study shows that these songbirds achieve precise coordination by adjusting the period between two consecutive phrases (inter-phrase intervals), depending on whether their song is answered, the phrase type used in the duet and the position of the inter-phrase interval within the duet. —> Read More Here
