A better way to make unnatural amino acids

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

17-03-2014

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 ...

Pond-dwelling powerhouse's genome points to its biofuel potential

21-02-2014

Duckweed is a tiny floating plant that's been known to drive people daffy. It's one of the smallest and fastest-growing flowering plants that often becomes a hard-to-control weed in ponds and small lakes. But it's also been exploited to clean contaminated water and as a source to produce ...

Swiss cheese crystal, or high-tech sponge?

29-01-2014

The sponges of the future will do more than clean house. Picture this, for example: Doctors use a tiny sponge to soak up a drug and deliver it directly to a tumor. Chemists at a manufacturing plant use another to trap and store unwanted gases. These technologies are what University at Buffalo ...

Crystal mysteries spiral deeper

11-10-2013

New York University chemists have discovered crystal growth complexities, which at first glance appeared to confound 50 years of theory and deepened the mystery of how organic crystals form. But, appearances can be deceiving. Their findings, which appear in Proceedings of the National Academy of ...

Tiny bottles and melting corks

Temperature regulates a new delivery system for drugs and fragrances

23-09-2013

Microscopic, bottle-like structures with corks that melt at precisely-controlled temperatures could potentially release drugs inside the body or fragrances onto the skin, according to a recently published study. Typical drug delivery systems act more like sponges than bottles. For example, drugs ...

Researchers create 'soft robotic' devices using water-based gels

05-08-2013

Researchers from North Carolina State University have developed a new technique for creating devices out of a water-based hydrogel material that can be patterned, folded and used to manipulate objects. The technique holds promise for use in "soft robotics" and biomedical applications. "This work ...
