DNA é a molécula que armazena toda a informação genética dos seres vivos, sendo responsáveis por determinar como os ...

Researchers in Japan say they have identified all five nucleobases that make up DNA and RNA in samples brought back from the asteroid Ryugu by the Japanese space probe Hayabusa2. Scientists from the ...

A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, guanine, cytosine, thymine, and uracil. When you purchase through links on our ...

A new study adds to a growing body of evidence that suggests asteroid impacts played a critical role in the emergence of life on our planet. Reading time 3 minutes Early Earth was a brutally hot, ...

There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...

According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...

Scientists at Rutgers University–Newark have developed a first-of-its-kind RNA-based nanotechnology that assembles itself inside living human cells and can be programmed to stop propagation of harmful ...

QIMR Berghofer scientists have discovered a cancer-fighting RNA molecule that could hold the key to a new way of treating the most common form of breast cancer. The team are developing their findings ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests could have quickly formed in the presence of compounds called borates. When ...

Researchers have sequenced the oldest RNA ever recovered, taken from a woolly mammoth frozen for nearly 40,000 years. The RNA reveals which genes were active in its tissues, offering a rare glimpse ...
