Building blocks of language evolved 30-40 million years ago
The capacity for language is built upon our ability to understand combinations of words and the relationships between them, but the evolutionary history of this ability is little understood. Now, researchers from the University ...

Transcription factors may inadvertently lock in DNA mistakes
Transcription factor proteins are the light switches of the human genome. By binding to DNA, they help turn genes 'on' or 'off' and start the important process of copying DNA into an RNA template that acts as a blueprint ...

Gut bacteria is key to bee ID
For a honey bee, few things are more important than recognizing your nestmates. Being able to tell a nestmate from an invader could mean the difference between a honey-stocked hive and a long, lean winter.

Scientists home in on the mechanism that protects cells from premature aging
Molecules that accumulate at the tip of chromosomes are known to play a key role in preventing damage to our DNA. Now, researchers at EPFL have unraveled how these molecules home in on specific sections of chromosomes—a ...
