The crash of meteors on early Earth likely generated hydrogen cyanide, which could have kick-started the production of biomolecules needed to make the first cells.

Researchers may have solved origin-of-life conundrum - The crash of meteors on early Earth likely generated hydrogen cyanide, which could have kick-started the production of biomolecules needed to make the first cells.

A team of paleontologists has discovered the oldest animal with a skeleton. Called Coronacollina acula, the organism is between 560 million and 550 million years old, which places it in the Ediacaran period, before the explosion of life and diversification of organisms took place on Earth in the Cambrian.

Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.
