Big Bang

Big Bang. Conceptual computer artwork representing the origin of the universe. The term Big Bang describes the initial expansion of all the matter in the universe from an infinitely compact state 12-15 billion years ago. The initial conditions are not known, but less than a second after the beginning, temperatures were trillions of degrees Celsius and the primordial universe was much smaller than an atom. It has been expanding and cooling ever since. Matter formed and coalesced into the galaxies which are observed to be moving away from each other as they are carried by the expanding universe. Background radiation in the universe is considered a remnant of the Big Bang

False-col SEM of yeast cells

Yeast. Coloured scanning electron micrograph (SEM) of yeast cells, Saccharomyces cerevisiae, commonly known as Baker's or Brewer's yeast, growing on potato dextrose agar. Yeast is able to ferment sugar, producing alcohol & carbon dioxide in the process. It has long been used in the brewing of beer, the production of wine and in baking of leavened bread (carbon dioxide causes the dough to rise). Medically, dried yeast is used as a source of vitamin B1, riboflavin & nicotinic acid. Yeast divide rapidly by budding off new cells (visible here). They may also reproduce sexually. Magnification: X 430 at 35mm size. Coloured orange. Original is BW print B250/171
