Chameleon Star Baffles Astronomers

Chameleon Star Baffles Astronomers

Pulsars — tiny spinning stars, heavier than the sun and smaller than a city — have puzzled scientists since they were discovered in 1967. Now, new observations by an international team, including University of Vermont astrophysicist Joanna Rankin, make these bizarre stars even more puzzling. The scientists identified a pulsar…

Noise Protection: Multifunctional and Aesthetical

Noise Protection: Multifunctional and Aesthetical

Noise abatement is growing in importance, thus, the demand for better acoustic building components raises. Scientists are developing new solutions: aesthetically good looking and flexibly applicable microperforated sound absorbers. Too much noise causes illness. This is as an undisputed fact nowadays, and yet we’re still constantly assailed by noise as…

Investigating the Bystander Effect Using Virtual Reality

Investigating the Bystander Effect Using Virtual Reality

The bystander effect is well-known in behavioural psychology and suggests that the more people who witnessing a violent emergency the less likely it is that someone will intervene. It was first identified in the 1960s, but conducting research on the phenomenon has been difficult. Most experiments rely upon staging fake…
