The Hound of the Baskersvilles

The Hound of the Baskervilles is possibly the most popular of all of the Sherlock Holmes stories, written by Sir Arthur Conan Doyle and filmed at least 24 times since 1914. It was inspired by the regional mythology of the British Isles concerning hell-hounds and set largely on an area of moorland close to where Doyle was a general practitioner while writing the novel. Doyle wrote in the crime, detective, and mystery genres but had an interest in writing in what other genre as well?

Hot “Ice” May Cover Recently Discovered Planet

An odd planet the size of Neptune, made mostly of hot, solid water, has been discovered orbiting a nearby star and offers evidence that other planets may be covered with oceans. Called GJ 436b, the planet orbits quickly around a cool, red star some 30 light-years away. The planet is hot because it is near its star and under high pressure because of its mass. The planet is also likely blanketed by hydrogen-- conditions hardly conducive to life. But if there is water, there could be water on other planets in other solar systems and thus life as we know it.
