El sexo no es binario

Niñas y niños, hombres y mujeres, hembras y machos… muchos piensan que el sexo es un rasgo binario con dos categorías aisladas, pero la realidad es bastante más compleja.

APOE expression and secretion are modulated by mitochondrial dysfunction

This study presents compelling evidence that ApoE is upregulated in various models of mitochondrial respiratory chain dysfunction. The work is of fundamental interest for those studying neurodegeneration and the role of ApoE in Alzheimer's disease; future work will be needed to reveal the molecular basis of this dramatic phenotype.

Neural bases of freedom and responsibility

This review presents a broad perspective of the Neuroscience of our days with special attention to how the brain generates our behaviors, emotions, and mental states. It describes in detail how unconscious and conscious processing of sensorimotor and mental information takes place in our brains. Finally, the brain process for decision-making, and its relationship with individual free will and responsibility, are also described.

Ciencia, un bien público privatizado por grandes editoriales comerciales

La comunicación de resultados científicos es un negocio muy lucrativo y bastante desconocido para la ciudadanía. Un gigantesco oligopolio de editoriales comerciales nos vende, a precios millonarios, el acceso a los resultados de la investigación financiada con el dinero de todos. Sin embargo, este hecho apenas llama la atención del público.

It matters who does science

A monolithic group of scientists will bring many of the same preconceived notions to their work. But a group of many backgrounds will bring different points of view that decrease the chance that one prevailing set of views will bias the outcome. This means that scientific consensus can be reached faster and with greater reliability. It also means that the applications and implications will be more just for all.

Running throughout Middle-Age Keeps Old Adult-Born Neurons Wired

Long-term running maintains the wiring of “old” new neurons, born during early adulthood, within a network that is important for memory function during aging in mice.

Running Rewires the Aging Brain: Exercise Protects Memory Function

Physical activity, particularly running, has been found to rewire aging brains, helping to preserve memory functions.
Long-term running keeps older neurons wired, potentially preventing age-related memory loss and neurodegeneration.

Un hombre con parálisis vuelve a caminar gracias a una interfaz activada por sus pensamientos

El holandés Gert-Jan Oskam, que sufrió hace más de una década una lesión medular a causa de un accidente, ha recuperado el control natural de sus piernas paralizadas con la ayuda de un ‘puente digital’. Este sistema restablece la comunicación entre el cerebro y la médula espinal y transforma el pensamiento en acción con inteligencia artificial.

Walking naturally after spinal cord injury using a brain–spine interface

A spinal cord injury interrupts the communication between the brain and the region of the spinal cord that produces walking, leading to paralysis. Here, we restored this communication with a digital bridge between the brain and spinal cord that enabled an individual with chronic tetraplegia to stand and walk naturally in community settings.

Wireless Brain-Spine Interface: A Leap Towards Reversing Paralysis

Researchers have designed a wireless brain-spine interface enabling a paralyzed man to walk naturally again. The ‘digital bridge’ comprises two electronic implants — one on the brain and another on the spinal cord — that decode brain signals and stimulate the spinal cord to activate leg muscles.
Remarkably, the patient experienced significant recovery in sensory perceptions and motor skills.
