The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated as Dyson spheres. Go to...
Venus appears pale yellow in visible light, but ultraviolet images reveal dramatic dark and bright patterns moving with the planet’s upper sulfuric acid clouds. Scientists have known about these markings for roughly a century, yet the chemical identity of the...
As space missions become longer and ambitions for deep-space travel grow, scientists are working to understand how life beyond Earth may affect every system in the human body. Two years after her initial study took flight, Begum Mathyk, MD, and collaborators are...
When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning surfaces. Go to Source
Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in condensed matter systems such as gases and...
