Arsenic is a very toxic and carcinogenic element which occurs naturally in rock. Arsenic contaminates water, soil and crops in a large number of countries. In some developing countries, high levels of arsenic in springs used for drinking water and irrigation have lead to alarmingly high amounts of toxin both in water and cultivated crops.
For example, in Bangladesh, parts of India and in some regions of Nepal, where rice is a staple food and people therefore risk consuming large amounts of the toxin via the food chain, arsenic is a very serious problem. According to calculations by UNESCO, more than 20 million people may be exposed to chronic arsenic exposure in these areas alone. But arsenic is a global problem where both developing and industrialised countries are affected.Found the protein which governs arsenic absorption
Attempts to develop rice varieties which absorb less arsenic are underway already, but this discovery of the particular proteins involved may lead to these developments accelerating.
"But even though we are happy to have identified the proteins, our goal is still a long way off," says Markus Tamas.Contact:

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
