A better way to make unnatural amino acids

The findings have potential applications in cancer, infectious disease, Alzheimer's drugs

17-Mar-2014

Chemists at The Scripps Research Institute (TSRI) have devised a greatly improved technique for making amino acids not found in nature. These "unnatural" amino acids traditionally have been very difficult to synthesize, but are sought after by the pharmaceutical industry for their potential ...

A new wrinkle in the control of waves

Flexible materials could provide new ways to control sound and light

27-Jan-2014

Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to ...

Turkeys inspire smartphone-capable early warning system for toxins

23-Jan-2014

Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors ...

Personal care products are possible sources of potentially harmful parabens for babies

17-Jan-2014

Through lotions, shampoos and other personal care products (PCPs), infants and toddlers are likely becoming exposed to potentially harmful substances, called parabens, at an even higher level than adult women in the U.S., researchers have reported. They published their findings on parabens, which ...
