Fires can kindle biodiversity, sparking new approaches to conservation
Raging fires throughout the U.S. and Australia over the past year have put vulnerable species at risk. But not all blazes are devastating—in fact, fire can promote biodiversity. In grasslands, fires prevent trees and roots from taking hold. This allows grazing animals the space and vegetation they need to thrive. As the pattern of wildfires […]
Snippet: Giant hornets on the attack? Try a little water buffalo poop
Giant hornets, which were detected in North America for the first time last year, can devastate colonies of the most common type of honey bee. But in Asia, where the fearsome predators are native, honey bees mount a vigorous defense with intimidating behaviors and coordinated counterstrikes. Now, researchers have discovered that Asian bees employ another, […]
AlphaFold: The making of a scientific breakthrough
The inside story of the DeepMind team of scientists and engineers who created AlphaFold, an AI system that is recognised as a solution to «protein folding», a grand scientific challenge for more than 50 years.

La masa de edificios, máquinas y carreteras superará en 2020 a la de los árboles
Adeline Marcos Nos dirigimos hacia una ‘jungla de asfalto’, según un estudio publicado esta semana en la revista Nature. Edificios de hormigón y ladrillo, carreteras de asfalto, máquinas de acero y plástico y productos de todo tipo fabricados por el ser humano se están produciendo a un ritmo que supera ya el de la creación de […]
Un diciembre con gemínidas, eclipse solar y superconjunción de planetas
Agencia SINC A lo largo de la última década, las gemínidas siempre han despedido el año superando los 100 meteoros por hora y colocándose en el primer puesto del ranking anual de lluvias de estrellas, junto con las perseidas y las cuadrántidas. En 2020, su actividad se produce entre el 4 y el 17 de diciembre, aunque el […]
A Farewell to the Arecibo Observatory | SciShow News
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.
Insane in the Chromatophores
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: Aliens From Earth | Random Thursday
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?
The amazing brains and morphing skin of octopuses and other cephalopods | Roger Hanlon
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 […]
Why Do Things Keep Evolving Into Crabs?
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 […]

Los pulgares de los neandertales se adaptaron para sujetar herramientas con mango
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 […]
