The ability to detect and react to the smell of a potential threat is a precondition of our and other mammals' survival. Using a novel technique, researchers have been able to study what happens in the brain when the central nervous system judges a smell to represent danger. The study indicates that negative smells associated with unpleasantness or unease are processed earlier than positive smells and trigger a physical avoidance response.

Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative. Stem cell researchers have now found a previously overlooked part of our DNA, so-called non-coded DNA, that appears to contribute to a difference which, despite all our similarities, may explain why our brains work differently.

A lunar probe launched by the Chinese space agency recently brought back the first fresh samples of rock and debris from the moon in more than 40 years. Now an international team of scientists has determined the age of these moon rocks at close to 1.97 billion years old.

The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent articles use data from meteorites derived from Vesta to resolve the 'missing mantle problem' and push back our knowledge of the solar system to just a couple of million years after it began to form.

While researchers have discovered numerous cell types in the brain, this atlas of all cell types in one area -- the primary motor cortex -- is the first comprehensive list and a starting point for tracing cellular networks to understand how they control our body and mind and how they are disrupted in mental and physical disorders.
