Fires in West Africa The West Africa biomass burning season that began in November 2002 is still underway in late March 2003. This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Aqua satellite on March 24, 2003, shows scores of fires (in Red) heavily concentrated in Sierra Leone, with other fires scattered across Guinea (top) and Liberia (bottom right).

Scientists using NASA satellite data have found the most intense global pollution from fires occurred during droughts caused by El Niño. The most intense fires took place in 1997-1998 in association with the strongest El Niño event of the 20th century.
Bryan Duncan, Randall Martin, Amanda Staudt, Rosemarie Yevich and Jennifer Logan, from Harvard University, used data observed by NASA’s Total Ozone Mapping Spectrometer (TOMS) satellite to quantify the amount of smoke pollution from biomass burning over 20 years.
"It’s important to study biomass burning, because those fires produce as much pollution as use of fossil fuels. Most of the pollution from fires is produced in the tropics, while pollution from fossil fuel use occurs in North America, Europe and Asia," Logan said.

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is...
At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
