Seeing concentrations of toxins with the naked eye

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a fast and cost-effective method to test liquids for a ubiquitous family of chemical compounds known as amphiphiles, ...

Team develops method for neural net computing in water

Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the manipulation of ions in liquid ...

A better understanding of crop yields under climate change

You don't need a Ph.D. in agriculture to know that water is critical to crop production. But for years, people like Jonathan Proctor, who has a Ph.D. in Agriculture and Resource Economics from the University of California ...

Programming pH: New technique could accelerate DNA synthesis

pH—the concentration of protons in a watery solution—indicates how acidic the solution is. It regulates a broad range of natural and engineered chemical processes, including the synthesis of designed DNA sequences for ...

Diamond mirrors for high-powered lasers

Just about every car, train and plane that's been built since 1970 has been manufactured using high-power lasers that shoot a continuous beam of light. These lasers are strong enough to cut steel, precise enough to perform ...

Tear-free brushing? All you need is math

As anyone who has ever had to brush long hair knows, knots are a nightmare. But with enough experience, most learn the tricks of detangling with the least amount of pain—start at the bottom, work your way up to the scalp ...
