Unraveling the G4 knot: How cells untie DNA to protect the genome

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play important roles in turning ...

Is your gut microbiome a calorie 'super harvester'?

In the jungle of microbes living in your gut, there's one oddball that makes methane. This little-known methane-maker might play a role in how many calories you absorb from your food, according to a new study from Arizona ...
