Along with annoyingly adhering to your TV screen and tabletops, dust can be a deadly material, exploding with enormously destructive force in places like coal mines, sugar refineries and grain silos. The explosive properties of normal dust are pretty well known, but what about non-traditional dust?

Consider the autoclave, which scientists use to sterilize tools and which issues scalding steam to do so. Or consider the heat gun, which is used to dry glassware and to warm distillation devices. It can also ignite anything flammable that gets too close. Glass containers in a vacuum can implode, spraying shards everywhere. Centrifuge rotors can fail, causing explosions that throw shock waves throughout a lab filled with chemicals. Steel vessels built to contain liquids and gases at hundreds of pounds of pressure per square inch can rupture, hurling metal at lab workers.
Earlier this month, scientists shared a tale of a desperate man whose daring effort to cure himself may have led to a new, albeit odd, medical treatment: swallowing worm eggs. But worm man is far from the first to take desperate measures in the name of progress. There's a long line of heroes who have knowingly and willingly exposed themselves to discomfort, danger or even death for science's sake.
Our sister site, Sound & Vision, has a great feature up on the various ways your nefarious home theater is trying to kill you--plus all the ways to foil its plans. Find out how to protect yourself from electrical shock, deep vein thrombosis, carpal tunnel syndrome, and explosive and/or concussive TVs over at the S&V site.
The Panoramic Survey Telescope and Rapid Response System, or Pan-STARRS, is stationed on top of Mount Haleakala in Hawaii, turning its 1.4 gigapixel camera on the skies in search of potentially hazardous objects. Now, just three months after its PS1 telescope went online, it’s found one.
While the machine uprising may not be upon us just yet, a group of University of Washington researchers has conducted a study on the various threats to security and privacy that household robots currently on the market could introduce to our homes. While their findings found little to fear in the way of an I, Robot-esque revolt, it turns out common household robots can open a home to various security and privacy threats, mostly via web-enabled features that are supposed to make the robots more useful.
Experts go head to head on the issue of nanotech safety

There´s nothing tiny about the international controversy brewing over the safety of nanomaterials. In April, a German company recalled a tile sealant called Magic Nano after dozens of consumers suffered breathing problems while using it. Never mind that the product contained particles too large to actually count as nanomaterials (which must be smaller than a billionth of a meter)-the scare was on, and European confidence in products labeled â€nanoâ€ had already sunk.
