An eight-year international research effort has produced the most comprehensive review of Honduras' mammals since 1998, verifying 227 native species across 146 genera and 42 families, along with three introduced rodent species. The study, published in the open-access journal ZooK

O ator Leonardo DiCaprio, o empresário Jeff Bezos e a mulher do magnata, a jornalista Lauren Sánchez, lançaram o Phoenix Species Project, iniciativa para salvar espécies em risco de extinção. O artista é amigo de Bezos, bilionário fundador da Amazon, e foi visto em seu casamento

The massive Toba eruption seems to have had little climate impact. O recorte ajuda a contextualizar a pauta dentro de Tech.

An international team of scientists has described seven new species of Madagascar's elusive diamond frogs (Rhombophryne), revealing that one of the island's most mysterious groups of amphibians is even more diverse than previously thought. The research is published in the journal

Deep in the forests of North Sumatra, Indonesia, lives the Tapanuli orangutan (Pongo tapanuliensis), the world's rarest great ape. Fewer than 800 individuals remain, confined to the Batang Toru ecosystem, a landscape that is also home to other rare species like Sumatran tigers, S

Imagine spotting a butterfly species in your garden that you have never seen before. You might take a photo and upload it to a citizen science app or tell a local nature group about your new encounter. It feels like a small moment of joy.

For the first time, researchers have discovered a new species of extinct amphibian from Ice Age Los Angeles at La Brea Tar Pits: a spadefoot toad they have named Spea labreae. Only one other extinct Pleistocene amphibian from North America has ever been found (a tree frog from Fl

Researchers sequenced the genomes of three medaka, or Japanese rice fish, a common model organism used in biological research, nearly 10 and 20 years ago. While sequencing the genomes was relatively straightforward, assembling them was anything but.

Smithsonian researchers have identified the genetic relationships among all Hawaiian honeycreeper species known to have existed—and subsequently faced major losses—since the arrival of Europeans to the islands.

Millions of sperm do not always compete alone—some species send them into action as coordinated teams. A sweeping evolutionary study found that this cooperation is widespread among arthropods and has repeatedly emerged and vanished over hundreds of millions of years. The discover

Scientists have uncovered a surprising way that “jumping genes” may move between species and speed up evolution. While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from a tiny predatory bacterium ins

Cristian Lucañas has discovered multiple species of cockroach in the Philippines, and believes there’s far more to the much-maligned insect than meets the eyeWhen Cristian Lucañas tells people about his job, their response is normally a mix of shock and confusion. “The majority w
