A dawning field of research, artificial biology, is working toward creating a genuinely new organism. At Princeton, chemistry professor Michael Hecht and the researchers in his lab are designing and building proteins that can fold and mimic the chemical processes that sustain life. Their artificial proteins, encoded by synthetic genes, are approximately 100 amino acids long, using

Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices — news to make the ears of Star Trek’s Spock perk up. Using DNA as a key tool, the interdisciplinary team took gold nanoparticles of different sizes and

A new self-healing fungi concrete, co-developed by researchers at Binghamton University, State University of New York, could help repair cracks in aging concrete permanently, and help save America’s crumbling infrastructure. Congrui Jin, assistant professor of mechanical engineering at Binghamton University, has researched concrete and found that the problem stems from the smallest of cracks. “Without

In an advance that could push cheap, ubiquitous solar power closer to reality, University of Michigan researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors. “For years, people had treated the poor conductivity of

Researchers program biomaterials with ‘logic gates’ that release therapeutics in response to environmental triggers Drug treatments can save lives, but sometimes they also carry unintended costs. After all, the same therapeutics that target pathogens and tumors can also harm healthy cells. To reduce this collateral damage, scientists have long sought specificity in drug delivery systems:

Chemists at The Scripps Research Institute (TSRI) have developed a fascinating new theory for how life on Earth may have begun. Their experiments, described today in the journal Nature Communications, demonstrate that key chemical reactions that support life today could have been carried out with ingredients likely present on the planet four billion years ago.

Ketone (fluorenone) polymer can fix hydrogen via simple electrolytic hydrogenation in water at room temperature and release hydrogen when heated to 80 degrees C.

Stanford scientists have invented a device that produces clean-burning hydrogen from water 24 hours a day, seven days a week. Unlike conventional water splitters, the Stanford device uses a single low-cost catalyst to generate hydrogen bubbles on one electrode and oxygen bubbles on the other. Credit: L.A.
