Viruses are sneakier than we thought
Viruses are molecular marauders, plundering cells for the resources they need to multiply. Of central importance for viruses is the ability to commandeer cellular gene expression machinery. Several human herpesviruses put ...

Scientists find shared genetic link between periodontitis and heart attack
The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years. Although a genetic link seemed likely, until now its existence was uncertain. Now, for the first ...

Researchers use multispectral images to reveal origin and evolution of Mercury
Up until last year globes of Mercury were blank on one side. The Mariner 10 spacecraft explored the small planet in three flybys (1974-1975), but since no more than half was ever seen it remained the least ...

Recycler protein helps prevent disease
Recycling is important not only on a global scale, but also at the cellular level, since key molecules tend to be available in limited numbers. This means a cell needs to have efficient recycling mechanisms. Researchers at ...
