Protecting genes, one molecule at a time

An international team of scientists have shown at an unprecedented level of detail how cells prioritise the repair of genes containing potentially dangerous damage. The research, published in the journal Nature and involving ...

Video shows the traffic inside a brain cell

Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell.

Discovery could reduce chemotherapy's side effects

A team of researchers at Duke University has determined the structure of a key molecule that can carry chemotherapy and anti-viral drugs into cells, which could help to create more effective drugs with fewer effects to healthy ...

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 ...

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 ...

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 ...

Is radon linked to health conditions other than lung cancer?

Radon, a naturally occurring radioactive gas produced when metals like uranium or radium break down in rocks and soil, is a known cause of lung cancer. Now, new research has found exposure to high levels of this indoor air ...
