A new study by researchers at the University of California, Berkeley, and the Harvard School of Public Health finds that promoting cleaner, more efficient technologies for producing charcoal in Africa can save millions of lives and have significant climate change and development benefits.
The African continent, as well as many developing nations in Asia and Latin America, is dependent on both wood and charcoal for cooking and heating homes. In 2000, nearly 470 million tons of wood were consumed in homes in sub-Saharan Africa in the form of firewood and charcoal. This is more wood per capita than is used in any other region in the world. However, more than 1.6 million people, primarily women and children, die prematurely each year worldwide (400,000 in sub-Saharan Africa) from respiratory diseases caused by the pollution from such fires, according to previous studies by the researchers.
The current study, published in the April 1 issue of the journal Science, concludes that by 2030, smoke from wood fires used for cooking will cause about 10 million premature deaths among women and children in Africa. By 2050, according to the report, smoke from cooking fires will release about 7 billion tons of carbon in the form of greenhouse gases to the environment. Thats about 6 percent of the total expected greenhouse gases from the continent.

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

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...
