But genetic analyses over the past two decades have revealed traces of several human ghost lineages in the ancestry of people today and in the ancient DNA recovered from fossils. These human ghost ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

Researchers at The Institute of Cancer Research, London, have uncovered how the DNA repair enzyme XPF-ERCC1 is recruited to sites of damage and activated inside cells, resolving a long-standing ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change.

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

Researchers suggest that they have recovered sequences from ancient works and from letters that may belong to the Renaissance genius. Historical artifacts can accumulate DNA from the environment and ...

Our hunter-gatherer ancestors have given us many things. They passed down mastery of fire for cooking and early survival technologies, such as stone tools. They may also have given us the secret to a ...

WILL TAKE THE STAND TOMORROW. OUR SARAH JOINS US LIVE OUTSIDE THE COURTHOUSE IN DEDHAM. SARAH. ERIKA AND BEN. TODAY WE HEARD KEY EVIDENCE ABOUT DNA ON EVIDENCE LIKE THE HATCHET AND HACKSAW. WE ALSO ...

My lords and masters and I are participating in Darwin's Ark feline program, and to be frank, if they use similar surveys I'm not surprised at the lack of definite results. I found - and have ...

Popular genetics tests can’t tell you much about your dog’s personality, according to a recent study. A team of geneticists recently found no connection between simple genetic variants and behavioral ...
