A simple rule drives the evolution of useless complexity

A new study at the University of Chicago has shown that elaborate protein structures accumulate over deep time even when they serve no purpose, because a universal biochemical property and the genetic code force natural selection ...

Extinct giant ape directly linked to the living orangutan

By using ancient protein sequencing, researchers have retrieved genetic information from a 1.9 million year old extinct, giant primate that used to live in a subtropical area in southern China. The genetic information allows ...

Archaea hold clues to ancient ocean temperatures

Solving a decades-old mystery, Stanford researchers have discovered proteins that enable hardy microbes called archaea to toughen up their membranes when waters are overly warm. Finding these proteins could help scientists ...

Scientists reveal how RNA gets spliced correctly

To carry out all of life's functions, proteins must be produced from instructions carried by genes within DNA and delivered to the cell's protein-making machinery by messenger RNA.

Diphthamide is an Achilles heel shared by both plants and animals

The biomolecule diphthamide is essential for the proper formation of proteins in cells. When humans are infected with diphtheria, diphthamide is altered by the diphtheria toxin so that life-threatening complications can arise ...
