SpaceX seeks U.S. approval for internet-via-satellite network

By Irene Klotz HOUSTON (Reuters) - Private rocket launch service SpaceX is requesting government approval to operate a massive satellite network that would provide high-speed, global internet coverage, according to newly filed documents with the U.S. Federal Communications Commission. The California-based company, owned and operated by technology entrepreneur Elon Musk, has proposed an orbiting digital communications array that would eventually consist of 4,425 satellites, the documents filed on Tuesday show. The project, which Musk previously said would cost at least $10 billion, was first announced in January 2015.

Underground ocean found on Pluto, likely slushy with ice

By Irene Klotz HOUSTON (Reuters) - Scientists have found evidence that tiny, distant Pluto harbors a hidden ocean beneath the frozen surface of its heart-shaped central plain containing as much water as all of Earth's seas. The finding, reported on Wednesday in two research papers published in the journal Nature, adds Pluto to a growing list of worlds in the solar system beyond Earth believed to have underground oceans, some of which potentially could be habitats for life. Pluto's ocean, which is likely slushy with ice, lies 93 to 124 miles (150 to 200 km) beneath the dwarf planet's icy surface and is about 62 miles (100 km) deep, planetary scientist Francis Nimmo of the University of California, Santa Cruz said in an interview.

Online game about lost sea hero helps scientists studying dementia

By Kate Kelland LONDON (Reuters) - An online game following the journey of an elderly former sea explorer who has lost his memories has helped scientists lead a vast international dementia study and given important preliminary results about human orientation skills. The game, called Sea Quest Hero and developed by Deutsche Telekom and Alzheimer’s Research UK, was launched in May and has already generated enough data to help create a global benchmark for the human brain's navigational processes and how they vary between men and women, and between the young and old. It has been played more than 2.4 million times worldwide, giving more than 9,400 years' worth of equivalent lab-based research, the scientists said on Wednesday - and is showing the potential to be able to help diagnose dementia earlier.
