UI study leads to better understanding of signaling capacity between neurons

The fundamental process of information transfer from neuron to neuron occurs through a relay of electrical and chemical signaling at the synapse, the junction between neurons. Electrical signals, called action potentials, cause voltage-gated calcium channels on the presynaptic neuron to open.

Deadly combination: Drug cocktail induces cancer cell death by switching off energy supply

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth - this was discovered by researchers from the University of Basel's Biozentrum two years ago. In a follow-up study, recently published in Cell Reports, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

Study provides new way to treat multiple sclerosis

Nerve cells stripped of their insulation can no longer carry vital information, leading to the numbness, weakness and vision problems often associated with multiple sclerosis. A new study shows an overlooked source may be able to replace that lost insulation and provide a new way to treat diseases like MS.
