FROM a rocky outcrop overlooking a limestone quarry in the desolate valley below, a fighter from Hizbullah surveys what just days before had been territory controlled by militants linked to al-Qaeda. “There were snipers behind every rock,” recalls the young man with a wispy moustache. The operation to drive the jihadists from their mountain lair on Lebanon’s north-east border with Syria began on July 21st. It took only a week for Hizbullah to defeat its militant rivals, adding yet another victory to its growing list of military achievements since war broke out in Syria six years ago.
Along with Russian air power and Iranian military aid, Hizbullah’s ground units have kept the regime of Bashar al-Assad, Syria’s blood-soaked president, in power. The cost has been high. About 2,000 of the
IN KIBERA, a slum in the south of Nairobi, Kenya’s capital, the tyres were burning by mid-afternoon. Across the country five people had been killed in protests and other violence. Several of them were shot by the police. A day after Kenyans voted for president, this was a hint of the menace that often lurks beneath the country’s elections. “It seems clear that somebody hacked this election,” said Kennedy Mhando, a 34-year-old clothes seller. “We want the actual results...If they are credible, we will accept them.” If not, “we will get the directives from our leaders.”
On August 8th some 15m Kenyans voted in an election to fill 1,882 positions. A few hours after polls had closed, provisional results released by the election commission showed that Uhuru Kenyatta, the incumbent president,
Experiments increasingly rely on high-performance computing software that plays a crucial role in producing and interpreting data. Differences in software environments can cause problems when those experiments need to be reproduced – so scientists at the MDC in Berlin are helping find a solution.Reproducing experiments and results is a cornerstone of science, but researchers acknowledge that actually achieving this feat can be tricky.

Fusion proteins consisting of antigens and the bacterial adjuvant flagellin are promising vaccine candidates. They have the potential to induce immune responses in a targeted and reliable manner, thus conveying protection against infectious diseases. In addition, they can favourably influence misdirected immune reactions, for example as part of a treatment against allergies. Researchers from the Paul-Ehrlich-Institut have now clarified the mode of action of such a candidate for the treatment of birch pollen allergies. In its edition of 05 September 2017, the Journal of Allergy and Clinical Immunology reports on the results of this research.To induce sufficiently strong immune responses during vaccination, either the antigen itself against which the immune response is directed at (for examp...
Ecosystems with high biodiversity are more productive and stable towards annual fluctuations in environmental conditions than those with a low diversity of species. They also adapt better to climate-driven environmental changes. These are the key findings environmental scientists at the University of Zurich made in a study of about 450 landscapes harbouring 2,200 plants and animal species.The dramatic, worldwide loss of biodiversity is one of today's greatest environmental problems. The loss of species diversity affects important ecosystems on...Powered by WPeMatico
Finger millet has two important properties: The grain is rich in important minerals and resistant towards drought and heat. Thanks to a novel combination of state-of-the-art technologies, researchers at the University of Zurich were able to decode the large and extremely complex genome of finger millet in high quality for the first time. This represents a fundamental basis for improving food security in countries like India and parts of Africa.For many poor farmers in India and Africa, finger millet is a major staple food. The crop species is not only a rich source of minerals like calcium, iron,...Powered by WPeMatico
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP will be introducing a new generation of organic photodiodes on silicon substrates (OPD-on-silicon) during the SEMI European Imaging & Sensors Summit 2017, September 20-22 in Grenoble, France, at MINATEC, Booth 42.Optical sensors are pervasive. Domestic life as well as the industrial environment are hard to imagine without them. For example, digital cameras using CMOS...Powered by WPeMatico
With a new technique to craft a spectrum of glowing dyes, chemists are no longer chasing rainbows.Swapping out specific chemical building blocks in fluorescent molecules called rhodamines can generate nearly any color scientists desire - ROYGBIV and beyond,...Powered by WPeMatico
G protein-coupled receptors are the key target of a large number of drugs. Würzburg scientists have now been able to show more precisely how these receptors act in the cell interior.The human genome encodes hundreds of G protein-coupled receptors (GPCRs). These form the largest group of receptors through which hormones and...Powered by WPeMatico
