Cientistas descobriram uma vasta estrutura geológica sob o gelo da Antártica Oriental, composta por bacias interconectadas, o que muda a compreensão sobre a história tectônica da região. A pesquisa foi liderada pelo Dr. Egidio Armadillo e publicada na revista Nature Geoscience.
Pesquisadores da Universidade de Columbia identificaram o mecanismo do resfriamento da estratosfera, que ocorre há décadas devido às mudanças climáticas causadas pelo ser humano. O estudo, publicado na revista Nature Geoscience, destaca a interação do dióxido de carbono com diferentes comprimento...

Un estudio recrea el interior de la Tierra y estima que el núcleo podría contener 0,07–0,36% de hidrógeno (hasta 45 océanos), clave para explicar su escasez en la superficie. https://aidoo.news/noticia/Wly1Zx
"Marine scientists drilling into abyssal ocean floor sediments discovered thriving colonies of this new #methanogen species at depths previously thought to be biologically inactive. These extreme environments, characterized by crushing pressure and complete darkness, harbor #microbial communities that have evolved unique metabolic pathways. According to research published in #NatureGeoscience, these #DeepSea methanogens can survive in conditions that would kill most known life forms.
"The discovery challenges everything scientists thought they knew about where life can exist in Earth’s oceans. These microbes don’t just survive in the deep ocean trenches, they’re actually flourishing and producing methane at industrial scales. Their metabolic processes operate entirely differently from surface-dwelling organisms, using chemical energy sources that most life forms can’t even process."

European climate extremes during the past 600 years were in large part driven by changes in the position and strength of the jet stream over the Atlantic, according to an analysis of terrestrial hydroclimate records.

📢 Scientists have found a mysterious source of oxygen at the bottom of the Pacific Ocean, far from any sunlight needed for photosynthesis. This phenomenon, discovered in a region rich with polymetallic nodules, suggests an unknown energy source might be splitting water molecules to produce oxygen. https://www.nature.com/articles/d41586-024-02393-7
