Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment.



Psychosocial issues and AIDS

Psychosocial influences such as stress have been neglected in biomedical and treatment studies involving people infected with HIV, yet they are now known to have significant health impacts.



Walking for health

A new study shows that a variety of interventions designed to promote walking can effectively motivate individuals to initiate walking behaviours.



Harnessing the power of light

Princeton engineers have invented an affordable technique that uses lasers and plastic beads to create the ultra-small features that are needed for new generations of microchips.



Stress early, allergies later

Stress events during childhood are increasingly suspected of playing a role in the later development of asthma, allergic skin disorders, or allergic sensitisations.
