Human health is the Achilles heel of space travel. Researchers at ETH Zurich have now succeeded in printing complex muscle tissue in zero gravity. This will enable drugs for space missions to be tested in the future. Go to Source
An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling scientists. Go to Source
Casting a swirling shadow, a glowing candle flame sways eerily before flaring up once more. As ghostly as it looks, this flame dance is not the result of any force—paranormal or otherwise—but rather the lack of one: gravity. Go to Source
Ballistic electrons are among the most fascinating phenomena in modern quantum materials. Unlike ordinary electrons, they do not scatter off imperfections in the material and therefore travel from A to B with almost no resistance—like a capsule in a pneumatic tube....
For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay is a process in which an atomic nucleus “captures” an...
