You have probably seen leaf-cutter ants carrying bits of plants, maybe in a nature documentary, at a science museum or in the “Circle of Life” song at the beginning of the 1994 Disney animated film “The Lion King.” Those ants don’t eat the leaves — instead they bring them back to their nests to feed a [...]

 The geology of Brazil's volcanic Trindade Island has fascinated scientists for years, but the discovery of rocks made from plastic debris in this remote turtle refuge is sparking alarm. Melted plastic has become intertwined with rocks on the island, located 1,140 km (708 miles) from the southeastern state of Espirito Santo, which researchers say is evidence of humans' growing influence over the earth's geological cycles. "This is new and terrifying at the same time, [...]

No intestino de bebês recém-nascidos, uma bactéria conhecida como Bifidobacterium longum tem o papel fundamental de quebrar os carboidratos do leite e auxiliar na digestão da única fonte de alimento dos pequenos. Outra importante função da espécie é inibir a proliferação de microrganismos causadores de doenças, ajudando a equilibrar a microbiota intestinal. Mesmo depois que o bebê cresce e passa a ter [...]

There’s a ring around this dwarf planet which shouldn’t be there A small icy world far beyond Neptune possesses a ring like the ones around Saturn. Perplexingly, the ring is at a distance where simple gravitational calculations suggest there should be none. Read more at straitstimes.com.

New telescope data has revealed that a dwarf planet in the outer reaches of the solar system has a dense ring around it, leaving scientists and astronomers confused as to why. Scientists at the European Space Agency announced Wednesday that data and observations of the planet Quaoar which was collected between 2018 and 2021 —from ground-based telescopes, and the space-based telescope Cheops — led them to the discovery. The ESA disclosed that Quaoar crossed in front of a [...]

Nature research paper: A dense ring of the trans-Neptunian object Quaoar outside its Roche limit The authors report observations of a dense and inhomogeneous ring at a surprisingly large distance from the trans-Neptunian body Quaoar. Federal University of Rio de Janeiro - Observatory of Valongo, Rio de Janeiro, Brazil B.Scientists are now wondering why the dense material in Quaoar's ring has not come together to form a small moon, because the ring itself is"at a distance of [...]

The small distant world called Quaoar, named after a god of creation in Native American mythology, is producing some surprises for astronomers as it orbits beyond Pluto in the frigid outer reaches of our solar system. Researchers said on Wednesday they have detected a ring encircling Quaoar akin to the one around the planet Saturn. But the one around Quaoar defies the current understanding of where such rings can form – located much further away from it than current scientific [...]
