Current Biology is a biweekly peer-reviewed scientific journal that covers all areas of biology, especially molecular biology, cell biology, genetics, neurobiology, ecology, and evolutionary biology. The journal includes research articles, various types of review articles , as well as an editorial magazine section.
Halophiles (organisms that thrive in highly salty environments) and hyperthermophiles (organisms that thrive in extremely hot environments) are examples of Archaea. [1] Archaea are relatively small. They range from 0.1 μm to 15 μm diameter and up to 200 μm long, about the size of bacteria and the mitochondria found in eukaryotic cells.
The Biology program featured the recurring segment "Biolo-graphy", during which Hank relayed a short biography of someone who was associated with the topic of the episode. Additionally, at the conclusion of each episode, Hank provided YouTube annotations with links to every subtopic he explained within the video.

For example, the release of molecular oxygen by cyanobacteria as a by-product of photosynthesis induced global changes in the Earth's environment. Because oxygen was toxic to most life on Earth at the time, this posed novel evolutionary challenges, and ultimately resulted in the formation of Earth's major animal and plant species.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
Botany, also called plant science or phytology, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. [1] A botanist, plant scientist or phytologist is a scientist who specialises in this field.
For example, wheat has a very large, complex genome which is difficult to study. In 1994 research from the John Innes Centre in England and the National Institute of Agrobiological Research in Japan demonstrated that the much smaller rice genome had a similar structure and gene order to that of wheat.
