Unlike traditional microscopes, which use light, the new approach uses DNA 'bar codes' to label each molecule in the cell. From readings of the complex interactions of these labels with the molecules ...

Current genetic sequencing techniques can provide much information about the genetic makeup and activity in a sample, like a piece of tissue or a drop of blood. But they are unable to reveal where ...

Standard genetic sequencing approaches can tell you a lot about the genetic makeup and activity in a sample, like a piece of tissue or drop of blood. But they don’t tell you where specific genetic ...

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged. Cellular DNA is continuously exposed to both ...

Defense attorneys in the Scott Peterson trial have called mitochondrial DNA evidence questionable science, frustrating experts and putting under a microscope what has become a mainstream tool of ...

A proposal to retain DNA samples taken from people who have been arrested but not charged with a crime for up to five years has come under criticism from the Joint Committee on Human Rights. On the ...

DNA microscopy allows scientists to look inside a tissue sample and map active genes, color-coded and in 3D.Credit: Weinstein et al./Cell 2019 (3). Joshua Weinstein spent hours in graduate school ...

At-home DNA tests are becoming a popular holiday gift over the holidays. A recent survey by MIT found that 100 million Americans are on track to take one by the end of the next year. This trend offers ...
