Building a better bulletproof vest

The first bulletproof vest, made by the Polish inventor Jan Szczepanik. Bullets don’t just bounce off Superman, they don’t even slow him down. Real-life police and soldiers can’t say the same, even when they’re wearing a bulletproof jacket of Kevlar or something similar. Although bullets don’t penetrate–the bulletproof material spreads their force–the force is still tranmsitted to the tissue underneath the bulletproof shell, causing severe bruising or even organ damage.

Now engineers from the Centre for Advanced Materials Technology at the University of Sydney have found a way to use carbon nanotubes to not only stop bullets penetrating material but actually rebound their force, so bullets can be repelled with "minimum or no damage to the wearer of a bullet proof vest.” (Via Science Blog.)

If they can just nail the X-ray vision, super-strength and flying stuff, they can break out the red-and-blue tights. (Image from Wikimedia Commons.)

Gun-barrel camera

gun barrel camera As a UK citizen, I’m getting used resigned to cameras appearing everywhere. But I can’t quite make my mind up about these gun barrel-mounted cameras that are being pilot-tested by police in Orange County, Illinois. I guess the idea is to make cast-iron evidence available from confrontations between police and suspects – it’s probably fair to say that in a situation where there’s a drawn gun in play, the heat of the moment may make eye-witness accounts less than reliable.

But the obvious potential for a new level of police-focused reality television can’t be ignored … and rather than making an officer think twice about drawing his gun, maybe he or she will feel they’re better protected by the evidence collected by having it in their hand with the camera running? Who can tell. One thing’s for sure, there’d be a lot less fog surrounding the de Menezes case if UK anti-terror cops had these things fitted to their weapons.

New lasers show cells in real time

danger99.gifTraditional microscope technology has been limited in resolution by a physical property of light called the diffraction limit. The diffraction limit states that light can only be focused into a beam as wide as half its wavelength. Researchers at Harvard University have overcome this limit by using nanoscale antennae to focus light down to beam as little as 100 nanometers in size.

The technique shows the most promise for biological imaging at the cellular level. Microscopes using the new lasers should be able to detect, for example, changes in individual proteins on the surfaces of cells.

Long-term energy solutions: Is nuclear our best option?

While we’re definitely big optimists here at Futurismic on alternative energies, there are downsides to most of what we consider clean energy.  Biofuels in their current incarnation pits the hunger of the poor against the hunger of our poor.  Solar is at the mercy of cloudy weather and efficiency concerns, while similar problems face wind power.  And coming from the Midwest United States, tidal power generators aren’t going to do me a lick of good.

The far-thinking people at the Long-Now Foundation had two very fascinating speakers back in September whose theory is that nuclear is the way to go.  They’re not your usual nuclear shills, either.  Gwyneth Cravens wan an anti-nuclear activist who marched against the bomb and against the Shoreham Nuclear Power Plant on Long Island.  The other is an sustainable organic-farming, bee-keeping, nuclear expert at Sandia Labs called Dr. Richard Anderson.

Their point is that alternative energies are largely tied to the whims of nature, something not good enough to supply the baseload power for our energy needs.  They do bring up some scary thoughts on our current use of fossil fuels, and make comparisons to what we would consume using nuclear.  One fun tidbit is that all the nuclear waste that would be generated to provide power for the average American over the course of their life would fit inside a Coke can.  Give it a listen if you can, but at least read the blog summary.

Personally, I think nuclear’s the way to go, at least for the moment, although I definitely think wind and solar can and should be used to provide supplemental power.  Maybe someday we can move to completely clean energy, but that day hasn’t come yet.

ZOMFG kkkonspiracy!!1

Wired has a run-down of the ten most popular conspiracy theories, which will either raise a wry chuckle out of you or fire you up into a paranoid rant-fest, depending on your personal belief systems.

I’m kind of fascinated by conspiracy theories, and when I was younger used to subscribe to quite a few (mostly the UFO-related ones, I’m ashamed to admit – a classic case of wishful thinking). Curiously, the book that completely cured the problem for me was Robert Anton Wilson and Robert Shea’s conspiracy classic, The Illuminatus! Trilogy.

It’s apparently the innate pattern-recognition functions of the human mind that create conspiracy theories wherever we find a vacuum of fact surrounded by unexplained events … how long do we have to wait until Occam’s Razor becomes hardwired, I wonder?
