“Proton dripping” tests a fundamental force in nature

From PhysOrg.com:

Like gravity, the strong interaction is a fundamental force of nature. It is the essential “glue” that holds atomic nuclei—composed of protons and neutrons— together to form atoms, the building blocks of nearly all the visible matter in the universe. Despite its prevalence in nature, researchers are still searching for the precise laws that govern the strong force. However, the recent discovery of an extremely exotic, short-lived nucleus called fluorine-14 in laboratory experiments may indicate that scientists are gaining a better grasp of these rules.

Researchers create functioning synapse using carbon nanotubes

From PhysOrg.com:

Engineering researchers the University of Southern California have made a significant breakthrough in the use of nanotechnologies for the construction of a synthetic brain. They have built a carbon nanotube synapse circuit whose behavior in tests reproduces the function of a neuron, the building block of the brain.

Researchers make the leap to whole-cell simulations

From PhysOrg.com:

Researchers have built a computer model of the crowded interior of a bacterial cell that – in a test of its response to sugar in its environment – accurately simulates the behavior of living cells.
