Materials Today: Holes help to make sponges and English muffins useful (and in the case of the latter, delicious). Without holes, sponges wouldn’t be flexible enough to bend into small crevices, and muffins wouldn’t be able to sop up the perfect…
IEEE Spectrum: In the puzzle of climate change, Earth’s oceans are an immense and crucial piece. The oceans act as an enormous reservoir of both heat and carbon dioxide, the most abundant greenhouse gas. But gathering accurate and sufficient data about…
Forbes: For the first time ever, astronomers using NASA’s Hubble telescope has reported the observation of a free-floating black hole wholly independent of a stellar mass companion. Heretofore, black holes have only been identified as supermassive objects at the centers…
Physics: Pulses of extreme ultraviolet (EUV) light are used to study very fast processes and very small things. Generating these pulses has become routine with a technique called high-harmonic generation, which uses an “upconversion” material to transform low-frequency pulses to…
New York Times: Ed Lu wants to save Earth from killer asteroids. Or at least, if there is a big space rock streaking our way, Dr. Lu, a former NASA astronaut…
