Rowhammer attacks make use of hardware vulnerabilities in order to access computer systems. TU Graz researchers have discovered a new type of attack - and raise questions about protective mechanisms. "When a system is regarded as absolutely safe, our curiosity is awakened," explains Daniel Gruss from the Institute of Applied Information Processing and Communication Technology working group, the researcher is occupied with the security of IT systems and in particular rowhammer attacks.

Under the leadership of the Environmental Sciences Research Network of the University of Vienna, the key national actors in long-term ecological research (LTER) join forces to establish a new infrastructure for the collection of environmental data. Funded by the Austrian Research Promotion Agency (FFG), the project aims to collect data on the effects of extreme climatic events on the carbon, water and nitrogen cycle in ecosystems by establishing six cutting-edge measurement sites.

Sharp metal needles can be used to emit electrons. A quantum effect opens up new possibilities of controlling electron emission with extremely high accuracy. In an electron microscope, electrons are emitted by pointy metal tips, that way the can be steered and controlled with high precision. Recently, such metal tips have also been used as high precision electron sources for generating x-rays.
