Colombia’s physical and socio-political landscape—a territory fragmented by mountain ranges and tropical forests, deficient infrastructure, lack of national integration, and the tradition of armed revolts against the central authorities—has provided fertile ground for guerrillas.

Starvation in the midst of plenty.

Solitons in the midst of chaos

A system of coupled nonlinear Schrödinger equations describes pulse propagation in weakly birefringent optical fibers. Soliton solutions of this system are found numerically through the shooting method. We employ Poincaré surface of section plots—a standard dynamical systems approach—to analyze the phase space behavior of these solutions and neighboring trajectories. Chaotic behavior around the...

The meddling microbes midst our medicines

It is not surprising that the complex metabolic machinery of the gut microbiome has accidental, or directed, ability to alter our medicines and influence their efficacy. What is not known is the extent to which this has contributed to drug failures or contraindications, or to the derailment of clinical trials. Some studies are unraveling the mechanisms by which the microbiota alter specific dru...
