Keynote Speaker discusses the science of discovery. Dr. Garret FitzGerald, a.k.a. “Big G” as faculty and students sometimes call him according to a 2001 Penn Medicine article, is a humble man with a proclivity for speaking about his research in equal medical and metaphoric terms. He fell into medicine through “a series of accidents” he thinks, though his earnest quest for knowledge is anything but. Born and bred in Graystones, Co. Wicklow, he went to high school at a time when specialization in either the arts or the sciences wasn’t required as it is now. His grandfather had been a professor of Greek, he says, “So I did Greek and Latin and French and German and English and Irish,” but also rounded out his linguistics with and math and physics. It’s clear his secondary school studies have stayed with him. ....
Credit: TU Wien T-cells are an important component of our immune system: with the receptors they carry on their surface, they can recognise highly specific antigens. Upon detection of an intruder, an immune response is triggered. It is still unclear exactly what happens when antigens are recognised: How many antigens are necessary to elicit an immune response, and does the response depend on their spatial arrangement? These effects take place in the nanometer range - on the size scale of molecules, far below what can be seen with ordinary microscopes. To study all this, tiny tools are needed. Therefore, an unusual method was used at TU Wien: DNA molecules were folded in an ingenious way, similar to the paper folding art origami. In this way, not just a double helix is created, but a rectangular molecular raft that floats across a cell membrane and serves as a tool for novel measurements. The results have now been published in the scientific journal ....
ZEISS Innovation Hub @ KIT Celebrates One-Year Anniversary The ZEISS Innovation Hub @ KIT was officially opened in a virtual event, one year after it became operational On 12,000 square meters the new building offers space for current and future startups and spin-offs by both partners. (Photo: ZEISS) The ZEISS Innovation Hub @ KIT is a milestone in the longstanding partnership between ZEISS and the Karlsruhe Institute of Technology (KIT). In the new building on KIT’s North Campus ZEISS enables high-tech and digital startups to move into the Hub, and is driving its own innovation and new business activities. The Hub has seen a number of successful collaborations and projects since it opened in early 2020. ....
E-Mail Metals such as gold or platinum are often used as catalysts. In the catalytic converters of vehicles, for example, platinum nanoparticles convert poisonous carbon monoxide into non-toxic CO2. Because platinum and other catalytically active metals are expensive and rare, the nanoparticles involved have been made smaller and smaller over time. Single-atom catalysts are the logical end point of this downsizing: The metal is no longer present as particles, but as individual atoms that are anchored on the surface of a cheaper support material. Individual atoms can no longer be described using the rules developed from larger pieces of metal, so the rules used to predict which metals will be good catalysts must be revamped - this has now been achieved at TU Wien. As it turns out, single atom catalysts based on much cheaper materials might be even more effective. These results have now been published in the journal ....
