TOM'S NERD NEWS:

It's time for "Tom's Nerd News," covering the news for your brain you may have missed the last few days.  Here's a quick rundown of this week in science . . .1.  SpaceX is going to fly four tourists into space and put them in an orbit around Earth that's even higher than the International Space Station.  They'll spend about five days up there.  It's not clear how soon it'll happen, or how much it'll cost.2.  In other space news:  Astronomers detected the first breathable oxygen OUTSIDE the Milky Way using a radio telescope.  They found it in a galaxy about half-a-billion light years away from us.3.  Researchers in Maine think LOBSTER BLOOD could be used to fight viruses, or even cancer.  Apparently there's a protein in it that helps boost your immune system, but they still need to do a lot of testing.4.  The next generation of solar panels could be a flexible "skin" that attaches to cars, homes, and wearable technology.  And it just had a huge leap forward after scientists in Australia broke a record for how quickly it converts sunlight into electricity.5.  And finally, doctors were worried this year's flu vaccine wouldn't work well, because it's a rare "double-barrel" flu season.  That's where two different strains are circulating.  But a new report from the CDC says it's worked surprisingly well, especially in kids.
