Purification removes contaminants from DNA samples, ensuring the integrity of the genetic material and providing more ...

Ancient DNA studies provide critical insights into human evolution and extinct species, leveraging advanced techniques to ...

It's been decades since thousands of human bones and bone fragments were unearthed on a suspected Indiana serial killer’s property ...

Most of the bones were crushed and burned, reducing their potential to yield usable DNA. Latham, a professor of biology and anthropology, said bone fragments deemed in poor shape are being held ...

That discovery led to the invention of the polymerase chain reaction, or PCR (as in the PCR tests we took during the pandemic), which enables scientists to select specific DNA fragments and then ...

The genetic sequence around that location could then be changed by adding a new DNA fragment, for example. Once a cut is made, it is a multistep, imperfect process of cellular DNA repair.

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, ...

A team from the University of Florida developed a microfluidic device for DNA purification that could speed up analysis of laboratory samples and match or exceed the purity of existing methods.
