Defecation duration is surprisingly similar throughout the mammal world. The average mammal defecates for 12 seconds, even though volume varies greatly between species.

Science & Technology Weekly Digest

Welcome to this week’s Learning Breeze Weekly Newsletter. Here, we explore how modern scientific tools are transforming the way we understand matter, life, and even our planet.

The key to why the universe exists may lie in an 1800s knot idea science once dismissed

In 1867, Lord Kelvin imagined atoms as knots in the aether. The idea was soon disproven. Atoms turned out to be something else entirely. But his discarded vision may yet hold the key to why the universe exists.

Microwave technique allows energy-efficient chemical reactions

Some industrial processes used to create useful chemicals require heat, but heating methods are often inefficient, partly because they heat a greater volume of space than they really need to. Researchers, including those from the University of Tokyo, devised a way to limit heating to the specific areas required in such situations. Their technique uses microwaves, not unlike those used in home microwave ovens, to excite specific elements dispersed in the materials to be heated. Their system proved to be around 4.5 times more efficient than current methods.
