Scientists discover simple method to measure density of engineered nanoparticles in physiological fluids

Thousands of consumer products containing engineered nanoparticles — microscopic particles found in everyday items from cosmetics and clothing to building materials — enter the market every year. Concerns about possible environmental health and safety issues of these nano-enabled products continue to grow with scientists struggling to come up with fast, cheap, and easy-to-use cellular screening systems to determine possible hazards of vast libraries of engineered nanomaterials.

Smokers find difficult to savor bitter taste of caffeine, says study

Smokers and those who have quit cannot fully appreciate the full flavor of a cup of coffee, because many cannot taste the bitterness of their regular caffeine kick. This is the finding of a study led by Nelly Jacob of the Piti--Salp-tri-re Hospital APHP in France, published in Springer's journal Chemosensory Perception.

Researchers use retro approach to produce new drugs

This alternative approach to creating artificial organic molecules, called bioretrosynthesis, was first proposed four years ago by Brian Bachmann, associate professor of chemistry at Vanderbilt University. Now Bachmann and a team of collaborators report that they have succeeded in using the method to produce the HIV drug didanosine.
