Researchers have found that people may have a tendency to form friendships with individuals who have a similar body odor. The researchers were even able to predict the quality of social interactions between complete strangers by first 'smelling' them with a device known as an electronic nose, or eNose. These findings suggest that the sense of smell may play a larger role in human social interactions than previously thought.

Using light-capturing proteins in living microbes, scientists helped reconstruct what life was like for some of Earth's earliest organisms. These efforts could help us one day recognize signs of life on other planets.

Researchers have developed a virtual robotic limb system which can be operated by users' feet in a virtual environment as extra, or supernumerary, limbs. After training, users reported feeling like the virtual robotic arms had become part of their own body. This study focused on the perceptual changes of the participants, understanding of which can contribute to designing real physical robotic supernumerary limb systems that people can use naturally and freely just like our own bodies.

A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study.
