Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, new research finds.

Sand, rice and coffee are all examples of granular materials.

Medications excreted in the urine or dumped into the toilet can end up in the water supply, just like lotions or cosmetics that wash off the body and go down the sink or shower drain. 

The science of what makes good chocolate has been revealed by researchers studying a 140-year-old mixing technique.

Since the Agricultural Revolution about 12,000 years ago, humans have been selectively breeding plants with desirable traits such as high grain yield and disease resistance.

Over the past several years, Stanford transformed its energy infrastructure by electrifying its heating system, replacing its gas-fired power plant with grid power, creating a unique system to recover heat, building massive tanks to store hot and cold water, and building a solar power plant.

A study from The University of Texas at Austin is the first published in a scientific journal to take an in-depth look at the challenging geologic conditions faced by the crew of the Deepwater Horizon drilling rig and the role those conditions played in the 2010 disaster.

Logic and memory devices, such as the hard drives in computers, now use nanomagnetic mechanisms to store and manipulate information. 

Advancements in zero-emission fuel cells could make the technology cheap enough to replace traditional gasoline engines in vehicles, according to researchers at the University of Waterloo.
