The nightmarishly complex wheat genome finally yields to scientists

Enlarge (credit: State Historical Society of North Dakota) Bread, like wine, is pivotal in Judeo-Christian rituals. Both products exemplify the use of human ingenuity to re-create what nature provides, and the fermentation they both require must have seemed nothing less than magical to ancient minds. When toasted, rubbed with garlic and tomato, doused with olive […]

Gene editing crunches an organism’s genome into single, giant DNA molecule

Enlarge / Individual chromosomes (right) have a complex organization when packed inside a cell’s nucleus (left). (credit: Thomas Ried/NIH) Complex organisms have complex genomes. While bacteria and archaea keep all of their genes on a single loop of DNA, humans scatter them across 23 large DNA molecules called chromosomes; chromosome counts range from a single […]

Pocket-sized DNA reader used to scan entire human genome sequence

Enlarge / Sequence on a stick. (credit: Oxford Nanopore) A few years back, a company called Oxford Nanopore announced it was developing a radically different way of sequencing DNA. Its approach involved taking single strands of the double helix and stuffing them through a protein pore. With a small bit of current flowing across the […]

A salamander with a genome 10 times the size of ours regrows lost limbs

Enlarge / It’s so cute! Let’s chop off its leg in the name of science. It’ll grow back. (credit: IMP Vienna) Some human tissues, like the liver and muscles, retain the ability to regrow after damage. But most of our bodies do not—if you lose a limb, the limb’s gone. But elsewhere in the animal […]

The 'Explosive' Bombardier Beetle Got Robbed by a Dingo for the Title of Most Interesting Genome

GIF GIF source: YouTube This week, the Pacific Biosciences SMRT Grant announced the lucky winner of the World’s Most Interesting Genome competition. The contest was voted on by the public and a dingo named Sandy won the day. But was that the right decision? No, Sandy is kind of like a doggo and it’s clear […]
