Oxygen is necessary to life. Humans and animals use oxygen to convert fats and sugars into the energy that keeps all life processes running and maintains the body’s temperature. At the same time, oxygen can also be harmful when it is converted into toxic oxygen particles that cause serious damage to tissues and organs.
We can detect changes in the amount of oxygen with certain sensors. These oxygen meters are essential in adapting the body’s metabolism during the changeover from an oxygen-rich to an oxygen-deficient environment.
The absence of PHD1 might also explain the mysterious adaptations of hibernating animals, with important implications for the preservation of organs for transplant. Such tissues often have to contend with prolonged oxygen deficiency, which destroys their viability for transplantation. If these organs could be kept in a ‘hibernation’ condition, perhaps more lives could be saved...Funding
This research was conducted by Julian Aragonés and colleagues in the ‘Functional genomics of cardiovascular and neurovascular biology and disease’ research group, led by Peter Carmeliet, within VIB’s Department of Transgene Technology and Gene Therapy, Katholieke Universiteit Leuven, under the direction of Désiré Collen.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
