The burden of malnutrition in Africa continues to rise and it is costing the continent billions of dollars in lost productivity as a direct consequence of the effects of lack of essential nutrients, vitamins and minerals in particular.
It is estimated that about 40% of people in Sub-Sahara Africa are affected by vitamin A deficiency. Vitamin A deficiency raises the risk of severe illness and death in children by as much as 23-40%, and is a major cause of blindness in many countries. Iron deficiency on the other hand affects more than 70% of the populations in Africa. Iron deficiency carries a higher risk of child birth complications and maternal deaths; it decreases normal mental development by as much as 40-60% and lowers school performance. But more importantly perhaps, anaemia due to iron deficiency diminishes work capacity and productivity by up to 15%.
A two day high level consultation convened by the New Partnership for Africa’s Development (NEPAD), and the Development Bank of Southern Africa (DBSA) in conjunction with the Global Alliance for Improved Nutrition (GAIN) sought to seek solutions to advance the food fortification agenda on the continent.

So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
