A massive study of ancient DNA from nearly 16,000 people across more than 10,000 years in West Eurasia reveals that directional selection has driven the spread or decline of hundreds of gene variants since the end of the Ice Age and that selection has actually accelerated since people transitioned from hunting and gathering to farming.

(#5225) Existe una pintura que se autorepara con la luz del sol

You know how animals have all these instincts, like birds and butterflies know exactly where to fly and when,and bees know their job and how to talk through dance, and cats know how to kekekekekek at things they want to hunt (even if we don't know why).

Well... where are OUR instincts? what if (this is the hear me out) the reason why we developed the intellect necessary to build civilization is not because we had something other animals didn't, but the exact opposite? what if a lack of essential hereditary memory forced us to get smart enough to figure shit out on our own, or die?

(#5196) El avance de Tu Youyou contra la malaria antigua

La premio Nobel Tu Youyou descubrió la artemisinina, un medicamento contra la malaria, en 1971 tras estudiar un texto médico chino de 1600 años de antigüedad, "Recetas de emergencia guardadas en la manga", y se dio cuenta de que la hierba de ajenjo dulce debía extraerse a baja temperatura en lugar de hervirse.

Mediante este método de extracción en frío, su equipo aisló la artemisinina, un tratamiento que se estima que salvó a decenas de millones de personas de la malaria.

Para demostrar su seguridad, Tu incluso probó el fármaco en sí misma antes de los ensayos clínicos, una decisión audaz que finalmente contribuyó a su Premio Nobel de Fisiología o Medicina de 2015.
