13 – Las frutas o los amigos

/ En este episodio, nuestro tema principal fue la evolución de un aspecto del cerebro humano: ¿en su historia tuvo más peso la dieta o la complejidad social que debía procesar? Platicamos sobre primates subidos a las ramas, sociedades de distintos tipos y frutos rojos sobre fondos verdes. También hablamos de un escalofriante estudio que sugiere que tres de los virus más temidos, Zika, dengue y el del Nilo, podrían hacer equipo dentro de nuestros cuerpos; y del descubrimiento de con qué parte del cuerpo las abejas perciben los campos magnéticos de la Tierra. ¡Ah! Y claro, no pudimos evitar que Pach mencionara a Elon Musk, porque #amor.

¡Acompáñennos!

Artificial Skin Allows Sensory of Magnetism

People use electricity on a daily basis on their phones to murder innocent fruit or abuse pigs, but it’s not really a conscious feeling. But now it can be through the development of a new sensory skin. Nature.comreleased a new study by Michael Melzer of the Leibniz Institute for Solid State and Materials Research in Dresden, Germany which claims to have developed electric skin, which grants…

Erik is not amused.

A recent study has revealed the disruptive effect of low-frequency electromagnetic radiation on birds.

Scientists observed the European robin to explore how migratory birds orient to the Earth's magnetic compass. Image Source: nationalgeographic.com In an experiment three years in the making, Henrik Mouritsen, a professor of neurosensory sciences at the University of Oldernburg in Germany, and his team noticed this effect when one of the team’s members suggested using Faraday Cages—grounded metal boxes which screen the local electromagnetic fields generated by electronics while keeping the Earth’s static magnetic field intact—to correct an experiment that, at first, drew only random, disoriented results.

This brings new light into the long debate on the effects of weak electromagnetic fields on the environment, particularly upon animals which rely on magnetoception, the ability to orient themselves with the Earth’s magnetic field in order to navigate across long distances without need of the sun and stars. The frequencies of the waves that had the disorienting effect on the birds were much lower than the safety limits for humans imposed by the World Health Organization. These frequencies are common in urban areas and their disruption may provide an explanation for the recent drop in migratory bird populations in highly urbanized countries.
