On December 1, 2020, Arecibo’s long-story came crashing down to an end. While it’s sad to see this monumental observatory go, it’s worth looking back over the many discoveries it’s made over the last 60 years.
During experiments on the axons of the Woods Hole squid (loligo pealei), we tested our cockroach leg stimulus protocol (an iPod) on the squid’s chromatophores. The results were both interesting and beautiful. More details can be found here: http://blog.backyardbrains.com/2012/0… and an explanation of how it works can be found on our TED talk: http://on.ted.com/Gage
Cephalopods like octopus, squid, and cuttlefish seem to be as alien as any alien creature from a sci-fi movie, and it’s fun to speculate that they could be aliens from another planet. But could they be aliens from right here on Earth?
Octopus, squid and cuttlefish — collectively known as cephalopods — have strange, massive, distributed brains. What do they do with all that neural power? Dive into the ocean with marine biologist Roger Hanlon, who shares astonishing footage of the camouflaging abilities of cephalopods, which can change their skin color and texture in a flash. Learn […]
For some reason, animals keep evolving into things that look like crabs, independently, over and over again. What is it about the crab’s form that makes it so evolutionarily successful that non-crabs are apparently jealous of it? Thanks to Franz Anthony for all of the ancient crab (and «crab») illustrations featured throughout this episode! http://franzanth.com/ And […]

Eva Rodríguez Un equipo internacional de científicos ha estudiado las diferencias entre los neandertales y los humanos modernos a la hora de utilizar las articulaciones de las manos para agarrar objetos. A través del análisis 3D, mapearon las articulaciones entre los huesos responsables del movimiento del pulgar –articulación trapeciometacarpiana– de cinco individuos neandertales y las […]
Dig into the science of coronaviruses and find out how they cause diseases such as SARS, MERS, and COVID-19.
At the beginning of this pandemic like everyone I was hearing lots about viruses, but realised I didn’t know that much about what they are. So I did a load of research and have summarised what I learned in these nine images. This video explains the key aspects of viruses: how big they are, how […]
Agencia SINC Dentro de la familia de los glóbulos blancos, los linfocitos T citotóxicos (CTL, por sus siglas en inglés) desempeñan un papel clave en la eliminación de células cancerígenas y aquellas que han sido infectadas por microorganismo patógenos. Para encontrar sus objetivos tienen que penetrar a través del complejo microambiente que rodea las células: la matriz extracelular […]
I’ve been fascinated with quantum physics and quantum mechanics for a very long time and I wanted to share the subject with you so I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you […]
Una explicación sencilla de la teoría matemática de Wolfram y sus posibles aplicaciones físicas.
In and out, in and out. Staying alive is about doing things. This very second, your cells are combusting glucose molecules with oxygen to make energy available, which keeps you alive for another precious moment. To get the oxygen to your cells you are breathing. Breathing is an answer to a very hard problem: How […]
Agencia SINC Después de la primera entrega de 2016 y la segunda de 2018, llega el Tercer Lanzamiento Temprano de Datos (Early third Data Release o EDR3) de la misión Gaia de la Agencia Espacial Europea (ESA), hecho público este jueves. La comunidad astronómica mundial lo esperaba con mucho interés. Esta tercera entrega de Gaia, la gran misión europea de […]
