Identical twins reveal mechanisms behind aging
In a recent study led by Uppsala University, the researchers compared the DNA of identical (monozygotic) twins of different age. They could show that structural modifications of the DNA, where large or small DNA segments ...

Researchers demonstrate why DNA breaks down in cancer cells
Damage to normal DNA is a hallmark of cancer cells. Although it had previously been known that damage to normal cells is caused by stress to their DNA replication when cancerous cells invade, the molecular basis for this ...

Small molecules can starve cancer cells
All cells in our body have a system that can handle cellular waste and release building blocks for recycling. The underlying mechanism is called autophagy and literally means "self-eating". Many cancer cells have increased ...
