Biology ^[NEW]

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, physiological mechanisms and evolution. Certain unifying concepts consolidate it into a single and coherent field that recognizes genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction.

CoronavirusPandemic ^[NEW]

The legislation, which Democrats hope to push through the Senate by the weekend, remains among the largest federal relief packages in modern American history. It would deliver hundreds of billions of dollars for vaccine distribution, hospitals, state and local governments and families struggling to recover from the economic toll of the coronavirus pandemic.

Vaccines ^[NEW]

Vaccines work by training and preparing the body’s natural defences – the immune system – to recognize and fight off viruses and bacteria. If the body is exposed to those disease- causing pathogens later, it will be ready to destroy them quickly – which prevents illness. When a person gets vaccinated against a disease, their risk of infection is also reduced.
