Determining the relative abundance of two different molecular species or the absolute number of molecules in a single sample is challenging. We describe an absolute counting method that can use ...

Approach involves generating a Unique Molecular Identifier prior to amplification. Scientists at the Karolinska Institutet and University of Helsinki have devised a method for counting individual RNA ...

Researchers have developed a method for generating numbers guaranteed to be random, through the use of quantum mechanics. The experimental technique surpasses all previous methods for ensuring the ...

To simulate chance occurrences, a computer can’t literally toss a coin or roll a die. Instead, it relies on special numerical recipes for generating strings of shuffled digits that pass for random ...
