As the adoption of electric vehicles continues to grow, so does the need for the safe and permanent storage of battery materials and industrial chemical waste. Certain waste streams require disposal in what are known as Category IV landfills, which impose particularly...
More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole spinning at extreme speeds. He proposed that a particle entering its ergosphere—a region of space dragged around by a rotating black hole—could...
Imagine trying to trap a miniature star inside a machine without letting it touch the walls or burn itself out. This is the central, high-stakes challenge of high-temperature plasma engineering. Go to Source
Shielding astronauts from the deadly radiation they face is a central challenge for any designer of a deep-space crewed mission. Even relatively low levels of exposure over long periods can lead to everything from central nervous system damage to cancer. But current...
By analyzing data from NASA’s Chandra X-ray Observatory, Dutch astronomers have investigated a young, oxygen-rich supernova remnant known as G292.0+1.8. Results of the new study, published June 29 on the arXiv preprint server, yield important insights into the...
