New theory of deep-ocean sound waves may aid tsunami detection

Researchers have now identified a less dramatic though far more pervasive source of acoustic-gravity waves: surface ocean waves, such as those that can be seen from a beach or the deck of a boat. These waves, known as surface-gravity waves, do not trav...

Cell biology: Nuclear export of opioid growth factor receptor is CRM1 dependent

The opioid growth factor receptor (OGFr) interacts with a specific opioid growth factor ligand (OGF), chemically termed [Met5]-enkephalin, to maintain homeostasis in a wide variety of normal and abnormal cells and tissues. The mechanism underlying the ...

Diabetic management: Subcutaneous insulin therapy fails to protect against oxidative stress and inflammation

Today, the gold standard for insulin therapy is the subcutaneous injection of insulin (CSII), despite a non-physiological route of administration with suboptimal glycemic control showed in some patients. Inability of CSII therapy to prevent inflammatio...

A new way to discover DNA modifications

DNA is made from four nucleosides, each known by its own letter -- A, G, C, and T. However, since the structure of DNA was deciphered in 1953, scientists have discovered several other variants that are often added to the DNA sequences to replace one of...
