Green HPC: Sustainability in the Data Centers of Tomorrow

Recooler with optional “adiabatic” pre-cooling. The visible filter mats are moistened with water if required.
Digital technologies have become an integral part of science and industry – but data centers are among the biggest energy consumers in the IT sector. High-performance computers in particular are essential for complex calculations in research, but at the same time cause high electricity costs and CO2 emissions. To meet these challenges, RWTH Aachen University is focusing on innovative solutions for energy efficiency and sustainable resource utilisation.
Neural Networks – The Basis of Modern AI

Neural networks are models inspired by the functioning of the human brain. They consist of artificial neurons that process information and communicate with each other. These networks enable machines to learn from data and recognise patterns without any explicit programming for each task. Examples include virtual assistants such as Alexa and Siri, translation tools such as Google Translate and creative AI systems such as ChatGPT. In this article, we will look at how neural networks work, what advantages and disadvantages they have and how RWTH Aachen University uses them.

The time has come! Since April 1, 2025, user certificates (S/MIME) can again be requested in the RA-Portal. After our previous certificate provider, Sectigo, terminated its contract on January 10, 2025, we now have a new provider. The German Research Network (DFN) and GÉANT have contracted a new provider for public-key certificates. The choice fell on the Greek trusted provider HARICA (Hellenic Academic & Research Institutions Certification Authority). HARICA is a certification authority of the Greek university network GUnet, is specially optimized for research institutions and meets the highest security standards.

Backing up important professional or private files, such as texts, images and other documents, is essential. Data loss can have catastrophic consequences, whether caused by technical mishaps, accidental deletion or even hardware theft. Data loss can also be caused by viruses or hacker attacks. Viruses can, for example, encrypt the hard drive and then demand a ransom. Here are some proven strategies and tools to ensure that your data always remains safe and accessible. You can also take a look at the category IT-Security on our website to find out more tips.
IT Security When Traveling

Those who frequently use public transportation are often reminded to take care of their personal belongings. The material damage caused by theft or loss is obvious. The dangers of data theft are perhaps less apparent but have equally serious consequences. These consequences include identity theft, unauthorized access to financial data and potential damage to your personal and professional reputation.
With the right IT security tips, you can reliably protect your data on the move and travel with peace of mind. In this blog post, you can find out how to protect your data effectively – whilst enjoying every trip in peace.
