Wie wirkt's?

Forscherin zu chinesischer Arzneipflanze mit Konfuzius-Preis ausgezeichnet

Sie sind ein echter Hingucker: die pinken Blüten der Seidenakazie. Der Baum erfreut sich in heimischen Parks und Gärten immer größerer Beliebtheit. In seiner ursprünglichen Heimat China wird er als Arzneipflanze genutzt. Wirken diese Inhaltsstoffe auch gegen Entzündungen? Das hat Pia Raab in ihrer Doktorarbeit an der Universität Graz genauer unter die Lupe genommen. Dafür hat die pharmazeutische Wissenschaftlerin kürzlich den Konfuzius-Preis erhalten.

Die Traditionelle Chinesische Medizin verwendet sowohl die Blüten als auch die Rinde des asiatischen Gewächses. „Vorwiegend gegen Schlafstörungen und Müdigkeit“, weiß die Forscherin. „Das Extrakt aus der Rinde wird zur Linderung von Schwellungen und Prellungen äußerlich genutzt.“ Daher hat sie sich mit der entzündungshemmenden Wirkung von Albizia julibrissin, so der botanische Name des Laubbaumes, beschäftigt. „Denn wir sind auf der Suche nach pflanzlichen Alternativen für Schmerzmittel, die weniger Nebenwirkungen haben als herkömmliche.

Raab hat sich dazu zum ersten Mal angesehen, ob jene Flechten, die auf der Seidenakazie wachsen, die aus der Rinde gewonnene Substanz beeinflussen. Ein einzelner Wirkstoff konnte zwar bislang noch nicht gewonnen werden. Die Absolventin hat jedoch mit ihrer Dissertation die Grundlage für weitere Untersuchungen gelegt, die in der Forschungsgruppe von Rudolf Bauer am Institut für Pharmazeutische Wissenschaften fortgesetzt werden – in Kooperation mit chinesischen Wissenschaftler:innen. „Denn die großen Herausforderungen unserer Welt lassen sich nur in Zusammenarbeit lösen“, bekräftigt Raab, die selbst vor Ort in China geforscht hat.
Dieses verbindende Motiv ist ein wesentlicher Aspekt des Konfuzius-Preises – dotiert mit 1000 Euro –, mit dem Pia Raab vor wenigen Tagen geehrt wurde. Überreicht wurde die Auszeichnung von Wan Jie Chen, Leiter des Konfuzius-Instituts.

A fresh start, a calling, holidays: what draws people from other career paths to teaching

They used to develop software; now they teach maths in the classroom. Career changers are expected to help address the shortage of qualified teachers in Austria’s schools.

Talent Talks bridge the gap in career guidance

The Styrian Chamber of Commerce (WKO Steiermark), the Styrian Chamber of Labour (AK Steiermark) and the AMS are joining forces when it comes to training young people and, through the “Talent Talks”, are creating a seamless pathway to career guidance. This takes preparation and follow-up support – just in time for the start of the term and the scheme’s tenth anniversary – to a whole new level. A new survey conducted by the Talent Centre among 2,687 former participants to mark the anniversary shows just how important this development is. Of the young people who received follow-up support from the Talent Report, 74.6 per cent stated that they had a good understanding of their own strengths and talents following the Talent Check. Without follow-up support, the figure was 66.5 per cent – a significant difference of 8.1 percentage points.

Austria’s emissions rose in 2025: University of Graz researchers analyse the causes

The Environment Agency Austria has today published the figures for the country’s greenhouse gas emissions in 2025. While emissions fell sharply year on year from 2022 to 2024, they rose again by just under 0.7 per cent in 2025. Researchers at the University of Graz have analysed how much of this increase was due to structural changes in the economy and how much was attributable to external factors over which there is little control. “In 2025, the colder winter compared with 2024 increased emissions by 0.81 per cent, while the weak economy reduced them by 0.38 per cent. If we factor out these influences, we find an underlying increase of 0.26 per cent compared with the previous year,” reports economist Karl Steininger. “This clearly means that Austria is not on track to meet its climate targets, which require a substantial reduction in emissions by 2030.”
