Hacking the programs of cancer stem cells

Scientists have discovered a molecule that interrupts biochemical signals essential for the survival of tumor cells called Wnt-addicted cancer stem cells. The discovery is the product of an approach known as 'rational drug design', targeting specific molecules based on a thorough understanding of the biology of a disease and the biochemical signals that support it.

Memory capacity of brain is 10 times more than previously thought

Scientists have achieved critical insight into the size of neural connections, putting the memory capacity of the brain far higher than common estimates. The new work also answers a longstanding question as to how the brain is so energy efficient and could help engineers build computers that are incredibly powerful but also conserve energy.

Biophysicists discover the key feature of an accurate tool for optogenetics

Biophysicists have developed a hypothesis to explain the function of a light-driven protein which pumps sodium ions across a cell membrane, and they have revealed the key structural feature of these pumps. The scientists see these sodium pumps as being highly promising tools in using light signals to control nerve cells - which is exactly what is involved in the new scientific field of optogenetics.
