Method Spots Counterfeit Drugs Five Times Faster

June 10, 2014 7:00 am | by Univ. of Montreal | News | Comments

Researchers have developed an improved chemical analysis method that is more efficient and faster in detecting counterfeit medications, which have skyrocketed in recent years. The method identifies and quantifies the various compounds present in a pharmaceutical product, in a fifth of the time it takes governmental services to do the same job.

Water Sheds Light on Surface of Nanocrystals

June 10, 2014 7:00 am | by Lawrence Berkeley National Laboratory | News | Comments

Reseachers found unexpected traces of water in semiconducting nanocrystals. The water, as a source of small ions for the surface of colloidal lead sulfide nanoparticles, allowed the team to explain just how the surface of these important particles are passivated, meaning how they achieve an overall balance of positive and negative ions.

Method Aids Study of Influential Cysteine Thiols

June 10, 2014 7:00 am | by Pacific Northwest National Laboratory | News | Comments

In all organisms, reduction-oxidation — or "redox" — regulation is essential for many biological processes. Key to understanding these processes is being able to determine how the post-translational modifications (PTMs) of proteins, which occur in this case on their cysteine residues, contribute to creating "redox switches" capable of regulating protein functions.

Researchers Uncover Skin Pigment's Light-absorbing Secrets

June 10, 2014 7:00 am | by MIT, David Chandler | News | Comments

Melanin— and specifically, the form called eumelanin— is the primary pigment that gives humans the coloring of their skin, hair and eyes. It protects the body from the hazards of ultraviolet and other radiation that can damage cells and lead to skin cancer, but the exact reason why the compound is so effective at blocking such a broad spectrum of sunlight has remained, until now, something of a mystery.
