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 ...

You could probably find a few biologists who are diehard protein partisans, and others who love lipids, but if a genie granted them one wish for what they could see inside living cells, most would ...

It’s not every day that something from the 17 th century gets radically reinvented. But this month, a team from the Broad Institute at MIT and Harvard took aim at one of the most iconic pieces of lab ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

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 ...

Every living thing has DNA, the blueprint for life. These genetic blueprints separate us as species and, further, as individuals. The human genome — the complete set of DNA found in all humans — is ...

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 ...

What looks like a kaleidoscope of glowing ice cream sprinkles or a cross between a nebula and a 1980s dance party is actually something even more astonishing: an unfettered and detailed view of the ...

Each of us has enough DNA to reach from here to the sun and back, more than 300 times. How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Long, slender DNA ...

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 ...
