In addition to its popular role in flavoring ice cream, fudge and cake frosting, vanilla may have a future use as a medicine. Recent laboratory research has strengthened the possibility that a form of vanilla may become a drug to treat sickle cell disease.
After specially bred mice received a compound that turns into vanilla in the body, they survived five times longer than mice that did not receive the chemical. All the mice had been subjected to low oxygen pressure, a condition that causes their red blood cells to form the hazardous sickle shape. Results of the study, led by research hematologist Toshio Asakura, M.D., Ph.D., of The Childrens Hospital of Philadelphia, appeared in the June 2004 issue of the British Journal of Haematology.
It had been known for 30 years that vanillin, the compound that gives the vanilla bean its flavor, protects red blood cells with sickle cell disease from assuming the sickle shape that obstructs blood vessels. However, this effect previously occurred only in test tubes, because vanillin normally breaks down in the digestive tract before reaching the bloodstream.
Scientists at Medinox, a San Diego-based biotechnology company, developed a variant of vanillin called MX-1520, chemically modifying it to resist degradation by the digestive system. MX-1520 is a prodrug--a compound that becomes an active drug (in this case, vanillin) in the body.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
