A team of chemical biologists at the University of Washington, working with colleagues at Oxford Nanopore Technologies, has developed a protein sequencing process that involves pulling proteins through nanopores in a lipid ...
Researchers have reconstructed the oldest human genomes ever found in South Africa from two people who lived around 10,000 years ago, allowing a better understanding of how the region was populated, an author of the study ...

Only about 10% of the world's roughly 4,000 snake species have venom strong enough to seriously hurt a human, but that's enough for snake bites to be an important public health concern. To help better understand how snakes ...

The human genome is the genome of Homo sapiens, which is stored on 23 chromosome pairs. Twenty-two of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs. The Human Genome Project (HGP) produced a reference sequence of the euchromatic human genome, which is used worldwide in biomedical sciences.
The haploid human genome contains an estimated 20,000–25,000 protein-coding genes, far fewer than had been expected before its sequencing. In fact, only about 1.5% of the genome codes for proteins, while the rest consists of RNA genes, regulatory sequences, introns and (controversially) "junk" DNA.
