The origins of neural variability

Neuroscience

By Jorge Mejías

Neurons are known to display irregular behavior in many areas of the brain. When recording the evolution of the membrane potential of a given neuron in the prefrontal cortex (for instance, during in vivo electrophysiology), we can observe its erratic dynamics, with spikes occurring in a random and rather unpredictable fashion. This one and other […]

PhysicsQuantum physics

By Daniel Manzano

Quantum mechanics is one of the most fruitful and accepted physical theories. Nevertheless, its foundations and philosophical implications are still a vivid topic of debate. Because of that reason, during the conference “Quantum Physics and the Nature of Reality,” held in July 2011 and organized by Anton Zeilinger, a set of experts were polled. A […]

When a standard kilogram is not a kilogram Tens of micrograms worth of surface contamination have caused the international standard kilogram to gain weight, according to new research, causing concern that each country’s standard weight for a kilogram is now slightly different. The cylinder-shaped piece of metal is key for scientific experiments that require exact […]

By Marisa Alonso Núñez

Killing cancer cells is a key point to cure cancer. Many researchers are working on developing different therapies to do just that. The one I’m going to talk about today is a very promising one: Oncolytic Virotherapy. Just the name may scare you but it’s a very clever approach to treat some tumors lacking a […]
