High wind delayed Northrop Grumman's supply run to the International Space Station on Friday.
Scientists have discovered thousands of exoplanets, including dozens of terrestrial—or rocky—worlds in the habitable zones around their parent stars. A promising approach to search for signs of life on these worlds is to probe exoplanet atmospheres for "biosignatures"—quirks in chemical composition that are telltale signs of life. For example, thanks to photosynthesis, our atmosphere is...
Every cell in our body has a computer-like control system that sends biological signals through thousands of circuits to monitor the cell's needs and regulate its responses.
The Breakthrough Listen Initiative today released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations.
Emerging technologies and new strategies are opening a revitalized era in the Search for Extraterrestrial Intelligence (SETI). New discovery capabilities, along with the rapidly-expanding number of known planets orbiting stars other than the Sun, are spurring innovative approaches by both government and private organizations, according to a panel of experts speaking at a meeting of the American...
The molecular blueprint of life is stored in DNA within the genome. The digital revolution in biology, driven by DNA sequencing, enables scientists to read the genomes of the many microbes and multicellular organisms that populate our world. Today, DNA sequences of over 200,000 microbial genomes are deposited in digital genome databases and have exponentially increased the understanding of how DNA...
