The science of champagne fizz

How many bubbles are in your bubbly?

04-04-2014

The importance of fizz, more technically known as effervescence, in sparkling wines and champagnes is not to be underestimated — it contributes to the complete sensory experience of a glass, or flute, of fine bubbly. A scientist has now closely examined the factors that affect these bubbles, and ...

Ancient whodunit may be solved: The microbes did it!

Methane-producing microbes may be responsible for the largest mass extinction in Earth's history

02-04-2014

Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out — by far the largest of this planet's five known mass extinctions. But pinpointing the culprit has been ...
