Medical Xpress / How a rare disorder triggers sweet aversion and fat buildup in the liver

Scientists at City of Hope have unraveled how citrin deficiency (CD), a rare genetic disorder that prevents the liver from converting food into energy efficiently, can trigger fat buildup in the liver—even in lean individuals.

Phys.org / Scientists identify first non-coding gene that controls cell size

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis behind cell size has ...

Medical Xpress / Hidden 'switches' in DNA reveal new insights into Alzheimer's disease

A tiny percentage of our DNA—around 2%—contains 20,000-odd genes. The remaining 98%—long known as the non-coding genome, or so-called 'junk' DNA—includes many of the "switches" that control when and how strongly genes ...

Phys.org / Saturn's biggest moon might not have an ocean after all

Careful reanalysis of data from more than a decade ago indicates that Saturn's biggest moon, Titan, does not have a vast ocean beneath its icy surface, as suggested previously. Instead, a journey below the frozen exterior ...
