News from Saxony

The noble butterfly Acraea terpsicore is spreading from India, Bangladesh and Sri Lanka further and further into South and Southeast Asia - and also ends up in photos taken by vacationers on their cell phones. It is precisely these images that make it an object of research. © S. Chowdhury/iDiv

Butterflies on Facebook - and research benefits

Vacation photos of colorful butterflies are not just beautiful memories - they can advance real science. Researchers from Leipzig and Jena have shown how images from social networks can help us understand the decline in biodiversity. Their result: surprisingly good.

Above-average rise in inflation in Saxony

Prices have risen significantly since 2020 - more than in the federal government. An Ifo analysis shows which areas have driven inflation in Saxony and why employees are still paid more in real terms.

Racism in public authorities? New study provides comprehensive data for the first time

For some people, discrimination begins at the official counter. A major study by the University of Leipzig has investigated for the first time how racist discrimination arises and continues in German authorities. The researchers came to the conclusion that it is not just a question of individual attitudes, but also of routines and the scope for decision-making in institutions.

Diversity slows down foreign plants

Two billion people live in arid regions. Researchers from Leipzig have now investigated the conditions under which non-native plants spread around the world. Their findings: heavy grazing and nutrient-rich soils favor the invaders. A high diversity of species protects against this.

More speed for autonomous cars and smart factories

Modern cars and factories need networks in which data not only arrives quickly, but also with pinpoint accuracy. The Fraunhofer IPMS in Dresden has developed a chip component that is ten times faster than previous solutions and works with nanosecond precision. The technology makes self-driving cars safer and production plants more efficient.

Drones reveal hidden particulate matter over large cities

Ground measuring stations only show part of the air pollution. An international study with Leipzig's participation proves this: At an altitude of 100 meters, particulate matter pollution can be 60 percent higher. Drones with inexpensive sensors help to close this knowledge gap and improve predictions.
