(Phys.org)—A pair of researches with the University of Texas has used a new method to infer historical human population size fluctuations based on Single Nucleotide Polymorphism (SNP) data. In their paper published in the ...
Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. ...

(Phys.org)—The traditional genome sequencing process requires thousands of cells (or more) to provide sufficient DNA, and this means that variations that are only present in a small number of cells―such as early cancer ...
(Phys.org)—In a soundproofed, vibration-stabilized, temperature-controlled room, Stanford biophysicist Steven Block was watching a very small origami project.
