The ventilation system in the Thialf ice stadium creates an airflow that affects the skaters. This is the conclusion of TU Delft aerodynamics researcher Alexander Spoelstra. He was commissioned by Thialf to closely map out the airflow, after skaters asked questions about the stadium's ventilation system. Spoelstra used a research set-up made up of lasers, helium bubbles and high-speed cameras. The technical report of the investigation was published online on 26 March.

In preparation for cell division, cells need to copy (‘replicate’) the DNA that they contain. A team of researchers from TU Delft, collaborating with investigators from the Francis Crick Institute in London, has now shown that the protein building blocks involved in the initial steps of DNA replication are mobile but reduce their speed at specific DNA sequences on the genome. Their findings, which will be published on 26 March in the open-access journal Nature Communications, were facilitated using an integrated approach involving biophysics and biochemistry that will propel new discoveries in the field.

The heart of any computer, its central processing unit, is built using semiconductor technology, which is capable of putting billions of transistors onto a single chip. Now, researchers from the group of Menno Veldhorst at QuTech, a collaboration between TU Delft and TNO, have shown that this technology can be used to build a two-dimensional array of qubits to function as a quantum processor. Their work, a crucial milestone for scalable quantum technology, was published today in Nature.

TU Delft researchers and 20 partners will develop reliable and safe wireless broadband connections using light instead of radio waves. They anticipate that this technology will allow us to securely send and process digital data at high speeds, with low latency. For this research project, the team has been awarded €4.1 million from the Dutch Research Council’s (NWO) Perspectief programme. TU Delft is also participating in the other five consortia that received Perspectief funding.

The authors of the 2018 article Quantized Majorana conductance have retracted this article. The authors were alerted to problems by two scientists in the same research area and then went on to re-examine their earlier measurements. In doing so, they found that the main conclusion had not been adequately substantiated.

Onderzoekers van de TU Delft hebben een test ontwikkeld waarmee ze specifieke stukjes genetisch materiaal kunnen opsporen, waarna de uitslag met het blote oog af te lezen is. Met de test kunnen onder meer virussen, zoals het coronavirus, en antibioticaresistente bacteriën snel en goedkoop worden gedetecteerd. De resultaten zijn gepubliceerd in Biophysical Journal.

Scientists of Wageningen University & Research, TU Delft and Erasmus MC have developed an online tool that helps determine how indoor spaces can be designed and used corona proof. With the OpenSmartTogether tool, restaurant owners can limit the risks of the spreading of the coronavirus in their restaurant. The researchers are inviting restaurant owners to participate in an online pilot.

Today, TU Delft launches Tech for Health | Better healthcare thanks to Delft technology. The university is shining a spotlight on its research innovations that contribute to the improvement of healthcare, especially in countries like The Netherlands.

Just like last year, the World University Rankings by Subjects 2021, published on 3 March, places TU Delft in a respectable 15th position in the broad category Engineering & Technology. Ten disciplines, including Architecture, Civil & Structural Engineering, Mechanical, Aeronautical & Manufacturing Engineering and Environmental Sciences, are ranked in the global top 20.

What does the Dutch population think about Dutch climate policy? Researchers from TU Delft and Utrecht University invite thousands of Dutch people to contribute their ideas.
