¿Recuerdas cuando sólo sabías que esto era una célula, y pensabas que eso era todo lo que tenía? 

Era casi tierna cuando tenía sólo unos organelos con funciones que se resumían en unas pocas líneas, y la mitocondria era lo más complejo y abundante que podía existir porque la materia que te pasaban de ella ocupaba dos páginas del cuaderno…

Y qué importaba cómo se relaciona? Para eso tenía unas lindas proteínas en la membrana que comunicaban y hacían magia…

…

Todo ese simple concepto queda atrás cuando tienes biología celular…

Simple concepto escolar de célula, ¡te extraño!

Noche de estudio de Biología Celular, ¡voy por ti!

A tardigrade (waterbear) hatching. 

Tardigrades reproduce sexually and females lay eggs. She’ll actually shed her skin first and then lay her eggs inside of it. The babies then hatch from their eggs and then have to crawl out of the skin husk. Fun fact: tardigrades are born with the same number of cells as their adult counterparts - their cells just get bigger as they age. 

Bacteria and fungi in petri dishes

Confused about what is meant by 5’ to 3’ and 3’ to 5’ in DNA? We have a GIF for that!

From the observed rate of expansion, astronomers can estimate the age of the universe. For every year, light travels one light-year across space. So the farthest parts of the universe that we can see are as distant in light-years as the universe is old in years. Light from more distant regions has not had time to reach us. This distance marks the limits of the observable universe–our “cosmic horizon.” Image: NASA Hubble Space Telescope
