Researchers from Duke University and the Howard Hughes Medical Institute discovered that an ingredient present in many natural proteins acts as a nanosprings of incredible elasticity. The material is called "ankyrin repeats and have the ability to stretch and re-contracting when subjected to loads with an elasticity similar to steel more than other organic materials.

These strings appear in proteins as diverse as plants or human beings, are formed by modules of 33 amino acids, and experiments were found by atomic force microscopy.

Amira Pharmaceuticals, Inc. announced it will present preclinical data on its program of LPA1 receptor antagonist on June 30, 2009 in the summer research conference of the Federation of American Societies for Experimental Biology (FASEB) held in Carefree, Arizona.

The LPA1 receptor is part of the phosphatidic acid path / lisofosfatidilcolina, which among other things is associated with the communication from cell to cell. In recent studies, it has been shown to play a role in fibrotic disease, particularly idiopathic pulmonary fibrosis (IPF).

The object of this research was to study quantitatively possibilities of a continuous process of production of perchloric acid from nitrogen peroxide and ammonium perchlorate. Perchloric acid has many properties which make it an important acid in industrial and analytical work and its use would be much greater if its cost of production could be lowered. It is a strong monobasic acid, stable in solutions (up to 60%), has a high boiling point. There are relatively few insoluble salts (potassium, rubidium, caesium, and thallium perchlorates are only highly soluble) and the difference in solubilities of potassium and sodium perchlorates give an easy method of separation of these two metals in analytical work.
