Cancer genetics: Angelina Jolie's decision

What about genetic screening? Angelina Jolie went public about her preventive mastectomy in an effort to focus publicity on surgery to prevent breast cancer. Can genetic sequencing help in cancer treatment? More »

Biobombs blast cancer!

Biobombs blast cancer!

We reported on viruses that infect cancer cells, force them to make more virus, and then die. Can viruses become “intelligent bio-agents” against cancer? More »

Bacteria: Social critters!?

Bacteria: Social critters!?

Bacteria: you’ve seen one, you’ve seen them all? Not. There’s a chemical war going on in that Petri dish, and a new study identifies specialist “super-killers” can kill off a broad range of competitors. Could “bacterial soldiers” help us fight resistance to antibiotics? More »

Seeing the cell

Seeing the cell
Imagine a transistor so tiny that it can slip inside a living cell to measure electrical potential. Now coat that transistor so the cell will pull it inside without damage. Then adapt the transistor to measure RNA and proteins. Nanofabrication tricks convert science fiction into science fact! More »

In detail: How learning changes brain

In detail: How learning changes brain
Changes in the junctions between nerve cells determine how well a bird will learn to sing. Regular change in these junctions helps the bird remember the song of its species, which it needs to learn to reproduce that song. Study could explain why older people have such trouble learning a new language. More »
