The Tausch’s goatgrass (Aegilops tauschii), also known as the rough-spike hard grass, is a self-pollinating goatgrass species in the Triticeae …

All robotic missions on Mars have been limited to the actual surface — rovers like Curiosity are reliable, but their range is limited. While Curiosity has driven more than 10 miles on the Martian surface, it took more than five years. A flying drone aircraft could cover much more distance, …

Our knowledge of exoplanets has expanded exponentially over the last 20 years, thanks to sophisticated search techniques and telescopes like Kepler. One of the problems with our data, however, has been that it’s much easier to find large gas giants or huge rocky worlds than it is to find Earth-like …

According to Heisenberg’s uncertainty principle, it’s impossible to know both the position and the speed of an electron at any one time. However, a team of physicists in Sweden has now shown that it can be done — through superposition (interference) of two short pulses of light with different wavelengths. …
