Slow-release 'jelly' delivers peptide drugs better

Duke University biomedical engineers have developed a new delivery system that overcomes the shortcomings of a promising class of peptide drugs – very small proteins – for treating diseases such as diabetes and cancer.

Axons' unexpected cytoskeleton structure

(Phys.org)—The plasma membranes that give cells their shapes are typically upheld by linear meshworks of the protein actin. In contrast, Howard Hughes Medical Institute scientists have now discovered that periodic ring-shaped ...

Scientists shed light on the 'dark matter' of DNA

In each cell, thousands of regulatory regions control which genes are active at any time. Scientists at the Research Institute of Molecular Pathology (IMP) in Vienna have developed a method that reliably detects these regions ...

Pocket test measures 50 things in a drop of blood

(Phys.org)—A new device about the size of a business card could allow health care providers to test for insulin and other blood proteins, cholesterol, and even signs of viral or bacterial infection all at the same time—with ...

Six degrees of inclination

(Phys.org)—Stay in a tilted bed for weeks with your head at the lower end and your body starts to change as if it were ageing prematurely or living in space. Twelve volunteers in ESA's bedrest study are enduring the testing ...

First successful total synthesis of Erythropoietin

(Phys.org)—"Blood is quite a peculiar kind of juice"—that is what Mephisto knew, according to Goethe's "Faust". But if blood really is very special, then erythropoietin (EPO) must be a very special molecule, as it triggers ...
