How does light sound?

Physicist Robert Nuster uses light to develop a process that makes razor-sharp images in 3D possible.

Detecting diseases at an early stage or to assessing the condition of donor organs without surgery requires precise images to be made of what is inside the body. In the future, a new process will deliver these images in razor-sharp 3D quality – using light. This light penetrates the tissue, becomes partially absorbed and converted into ultrasonic waves. Sensors then measure the propagation of these waves. A 1:1 image of what goes on inside our body is created based on the acoustic signals. The physicist Robert Nuster has further developed the method of “photoacoustic imaging” and has already used it to generate 3D images of blood vessels.

How does light sound?
Turning light into audible signals and 3D images sounds like science fiction. Photoacoustic imaging, however, has already become a reality. This method combines the possibilities of optical recording with those of ultrasound. The result is images that precisely reflect the condition of an organ, thanks to their high resolution and strong contrast. In the future, this method should help to make organs classified as non-transplantable due to minimal blemishes fit for use.

Complying with the norm: Why Do Standards Shape Our Lives, Elisabeth Staudegger?

Standards determine whether a sheet of paper fits in a printer or whether a charging plug can power multiple devices. These standards shape our everyday lives. But who actually sets these standards? Where are the weaknesses, and how could science help to improve them? Elisabeth Staudegger, Head of the ‘Law and IT’ Department at the Institute for Legal Foundations at the University of Graz, host the Academic Standards Day on 16 June. Here she relays how sciences can contribute to the topic of standardisation and reveals her personal favourite standard.

Survival strategies: How plants respond to drought

According to Geosphere Austria, this spring was the driest in Austria since records began around 170 years ago. The low rainfall put particular pressure on the agricultural sector. And climate change is set to make the situation even worse in the coming decades. We asked Johannes Liesche, a professor at the Department of Biology at the University of Graz, how plants react to water shortages and how they survive periods of drought.
