Hace 11 horas · The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. The similarities among all known present-day species indicate that they have diverged through the process of ...

Poco menos después de un mes de ser lanzado, el satélite EarthCARE de la Agencia Espacial Europea (ESA) ha enviado la primera imagen de uno de sus instrumentos: una imagen que, por primera vez desde el espacio, desvela la estructura interna y la dinámica de las nubes.. Esta extraordinaria primera imagen, captada por el radar perfilador de nubes a bordo del satélite ...
Hace 11 horas · However, EO is also vital to protecting our planet, providing data on Earth’s natural ecosystems that helps us track aspects such as the impact of greenhouse gases and progress in reducing GHG emissions. Earth observation provides a wide variety of data that can inform initiatives to fight GHGs and climate change. Image: World Economic Forum.
Hace 11 horas · We hypothesize that the first ancestral “protocell” molecular structures, i.e., the first RNAs and peptides that gradually transformed into real cells once the Earth had cooled sufficiently for organic molecules to appear, have left traces in the RNAs and the genes in present cells. We propose a circular RNA that could have been one of these ancestral structures whose vestigial pentameric ...
Hace 11 horas · La ambiciosa iniciativa Destination Earth (DestinE) de la Unión Europea, enmarcada en el Pacto Verde Europeo, tiene como objetivo responder a la necesidad urgente de mejorar nuestra capacidad para reaccionar mejor y adaptarnos a los retos medioambientales que plantean el cambio climático y los fenómenos extremos mediante el desarrollo de una réplica digital de gran precisión de nuestro ...

Hace 11 horas · Unravelling this mystery is vital for future research in brain evolution,” Baker explained. New research challenges the age-old belief that bigger bodies mean bigger brains. Scientists from the University of Reading reveal that brain size has a physical limit, with human brains evolving 23 times faster than other mammals.
