Climate forecasting systems help predict malaria risk in Africa
The Earth Institute at Columbia University—Malaria is one of the world’s biggest killers, taking the lives of more than 1 million people every year, as well as infecting a staggering 500 million worldwide. Although endemic in several regions of the world, malaria is most acute in Africa, home to an estimated 90 percent of all cases. Early warning systems can assist health programs and services in preventing and controlling the disease in epidemic-prone areas. A recent study shows that climate predictions can help provide health professionals and program managers with warnings of epidemics many months in advance. The study appears in the February 2 issue of Nature.
Climate variability has an important effect on malaria in epidemic-prone areas in Africa, where temperatures and rainfall drive both mosquito and parasite dynamics. In semi-arid Botswana, the National Malaria Control Programme has developed an early-warning system based on population vulnerability, rainfall, and health surveillance to predict and detect unusual changes in the seasonal pattern of disease. The risk of an epidemic in Botswana increases dramatically shortly after a season of good rainfall. Systems developed by the DEMETER project (http://www.ecmwf.int/research/demeter/) make forecasts of seasonal rainfall for much of southern Africa more reliable. An important influence on rainfall in this region is the El Niño/Southern Oscillation (ENSO) which impacts the occurrence of epidemic and non-epidemic years.

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...
