Thanks to a massive effort by 30,716 volunteers, scientists have pinpointed what appear to be seven precious specks of dust from outside the solar system, each bearing unique stories of exploded stars, cold interstellar clouds and other past cosmic lives.

The Herculean effort began eight years ago after NASA’s Stardust robotic probe flew by Earth to deposit a capsule containing samples from a comet and dust grains from what scientists hoped would be interstellar space. The spacecraft was outfitted with panels containing a smoke-like substance called aerogel that could trap and preserve fast-moving particles. Read more…

Collect Drilling Dust with an Envelope

Collect Drilling Dust with an Envelope

All you want to do is drill a little hole in your wall to hang a heavy picture or maybe a shelf. But no, you pull your drill out, drywall dust falls all over the floor, and now you’ve got to go find a broom or a vacuum. Why not save a little effort and catch that dust before it hits the floor?

Instrucables user Daghansa shows us how we can build a dust collector with just an envelope and a bit of tape. Sure, it’s a simple trick and dust is pretty easy to clean up anyway, but there are times this tip could be truly handy. If you’re hanging something over the bed, you may not want to get dust all over the headboard and pillows. And if you’re hanging something over a heavy piece of furniture, why not catch that dust before it falls down behind the furniture and becomes a real hassle to clean up? Oh, and if you don’t have an envelope handy, you could always try a sticky note.
