Energizing Africa – ScienceDaily

Southern Africa’s economy is developing rapidly, fueling a growing demand for electricity. Meeting these needs efficiently requires balancing social, economic, geographic, technological and environmental considerations. Researchers from UC Santa Barbara led an international team that analyzed the region’s resources and power grid. Using this data, they developed an energy portfolio that would most effectively meet …

Scientists identify novel molecular biomarkers in cells that spread deadly form of breast cancer – ScienceDaily

Johns Hopkins Medicine scientists, who study a deadly type of breast cancer called triple negative, say they have identified key molecular differences between cancer cells that adhere to an original tumor and those that dare to grow distant tumors. Research using mouse models and human tissue could pave the way for the development of new …

Over half of known human pathogenic diseases can be made worse by greenhouse gas emissions – ScienceDaily

A comprehensive review of the scientific literature has found empirical evidence that more than 58% of human diseases caused by pathogens such as dengue, hepatitis, pneumonia, malaria, Zika and more have – at one point – been made worse by climatic hazards. This revealing and surprising finding is the subject of a research paper published …

Causal treatment appropriate from infancy – ScienceDaily

Cystic fibrosis remains an incurable genetic disease that impairs lung function and significantly reduces life expectancy. A new drug combination therapy that addresses the underlying defects of the disease offers a promising new treatment approach. The use of this therapy has so far been limited to adolescents and adults. A study jointly conducted by the …

Engineer robotics discover alternative physics – ScienceDaily

A first step in understanding physics is identifying relevant variables. Columbia Engineers has developed an AI program to address a long-standing problem: whether it is possible to identify state variables from only high-dimensional observational data. Using video recordings of a variety of physical dynamic systems, the algorithm discovered the intrinsic dimension of the observed dynamics …

Solar kerosene: A giant leap for mankind

Until the Industrial Revolution, carbon dioxide (CO2) cycle kept our climate in balance. Nature’s photosynthetic cycle has “inhaled” CO.2 and water to create the oxygen we breathe and the energy-rich carbohydrates we consume—thus our atmospheric conditions have been stable with CO2 Concentrations at 287 ppm. Unfortunately, fossil fuels have upset the balance and atmospheric CO2 …

Science News | Researchers are tracking the source of nitrogen pollution affecting the world’s second largest barrier reef

Washington [US], August 6 (ANI): Tropical coastal ecosystems are among the most biodiverse areas on earth. And they are also at the forefront of the impact of human activity. Because of this, it is becoming increasingly important, especially as population numbers increase, to manage the impact of runoff and sewage flowing into the sea. “Tropical …
