It's been a hectic week for me, so I haven't had much time to search for interesting science tidbits. I'm sure some of you have heard that there may be salt water on Mars, or the building blocks of DNA have been found in meteorites. But did you know that the human brain is sensitive to light in the ears? Or that it may be possible for information to escape from a black hole? Extrasolar planets are becoming more common, but not when they're extremely dark yet glowing hot. Back on Earth, scientists are making quantum crystals and using genetically-engineered spider silk for gene therapy. I would be happy to settle for some massage therapy. ;)
Have a good weekend, and please let me know if you like this way of embedding the article links or if you prefer a straight list the way I normally do.
