BIOMEDICINE: Malignant Loss of Balance

Baroclinic Instability and Loss of Balance

Under the influences of stable density stratification and Earth’s rotation, large-scale flows in the ocean and atmosphere have a mainly balanced dynamics— sometimes called the slow manifold—in the sense that there are diagnostic hydrostatic and gradient-wind momentum balances that constrain the fluid acceleration. The nonlinear Balance Equations are a widely successful, approximate model for th...

Parton energy loss with detailed balance.

Stimulated gluon emission and thermal absorption, in addition to induced radiation, are considered for an energetic parton propagating inside a quark-gluon plasma. In the presence of thermal gluons, stimulated emission reduces, while absorption increases, the parton's energy. The net effect is a reduction of the parton energy loss. Though decreasing asymptotically as T/E with the parton energy,...

Autoimmune diseases, such as rheumatoid arthritis and multiple sclerosis, are complex disorders characterized by an inflammatory response against the body's own tissues. Recent findings reveal new insights into how these diseases are initiated and progress and the factors that contribute to their clinical symptoms. Such work also pinpoints potential new therapeutic targets including the integra...

This issue’s Biomedicine Select highlights new insights into the role of mitochondria in disease. Several new studies implicate abnormal mitochondria in the destruction of neurons of the substantia nigra, the cause of Parkinson’s disease (PD). Meanwhile, an elegant computational approach has enabled identification of candidate genes for several mitochondrial diseases including the mitochondrial...
