Some group with no modern descendants contributed a lot to our genomes. O recorte ajuda a contextualizar a pauta dentro de Tech.

Researchers from Trinity College Dublin have recovered and analyzed the first ancient smallpox virus genomes ever identified in the Americas, providing the strongest direct evidence to date that the disease was introduced through European colonization.

For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations and ancient DNA. Building on these approaches, researchers are increasingly using large population biobanks to i

Viruses lack the molecular machinery required for protein synthesis. Instead, they hijack the host's protein-making machinery, specifically ribosomes and translational factors. This process is essential for viral multiplication and infection. Viruses have RNA genomes or mRNAs con

Research identifies 808,585 viral genomes belonging to what scientists estimate to be 362,802 different virusesGet our breaking news email, free app or daily news podcastMore than a decade after the human microbiome was comprehensively mapped, scientists have now identified the v

A major DNA study has rewritten the koala's evolutionary story, revealing that the species suffered a dramatic population collapse about 100,000 years ago, long before humans arrived in Australia. By calculating the koala's mutation rate for the first time and analyzing hundreds

A hidden population of South African leopards has revealed a remarkable evolutionary story. Researchers analyzing entire leopard genomes discovered that the Cape Floristic Region’s leopards are not only much smaller than most African leopards, but also genetically distinct after

For more than three decades, researchers studying genomes have relied on foundational resources such as Repbase and, more recently, Dfam to identify and classify transposable elements—the mobile DNA sequences that shape genome structure, evolution and function. Now, Dfam and Repb

Researchers have spent decades—and billions of dollars—sequencing animal and crop genomes, but fungi have historically been the forgotten middle child of genomics, only noticed when they're ruining bread or colonizing toes.

In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first place.
