More alcohol
Ten percent more alcohol from fermentation. That is what biotechnology researchers from Professor Jack Pronk’s group (Applied Sciences) achieved in collaboration with Brazilian colleagues from the University of Sao Paulo and the Federal University of Santa Catarina.

Brazil has the world’s largest bioethanol production based on sugarcane. The yeast was genetically modified to take up sucrose and break it down in the cell (it normally does this outside of the cell), and subsequently put under evolutionary pressure.

Wrist watch

After a fall, bones in the wrist may change position, owing to torn ligaments for example. The displaced bones may cause pain and result in absenteeism long afterwards. Conventional imaging techniques however show no abnormalities. Dr Martijn van de Giessen (AS) developed a way to make the displaced bones visible by comparing the X-rays of a standardised set of movements with poses of healthy wrists. His computer model is able to distinguish between normal (green) and abnormal (red) bone gaps.


Rector Karel Luyben and Rijkswaterstaat ICT director Kees van der Kaa signed a research contract yesterday. Rijkswaterstaat will provide 800,000 euros in funding to geodetic and data research projects at the TU over the next four years. Research topics will include the capsizing of the Netherlands (east up, west down), data management policy (is Rijkswaterstaat’s data public or not), embedding laser scanning technology and setting up a 3D basemap of the Netherlands. OTB research institute is the primary scientific partner.
