I had a chance to play with these things a few days ago, and they're additively fun. In the video on the site you can see someone making all sorts of impressive geometric shapes with them with ease, but you don't have to be so precise. You can mold these things into perfect cubes, sure, but you can also make big clumps and work on making a beautiful sculpture with them. Or you can pull them all apart and toss them on a table and watch them all snap together as they roll around.

For $25, it's a little steep, but if you're looking for something to play with while you sit at your desk or watch TV, you could do a lot worse. [BuckyBalls]

The study used a computer simulation only, not actual physical science. And we don't know whether or not these carbon spheres would necessarily damage the cells they inhabit.

But that's exactly the point, right? While the complete biochemical theories behind these processes is admittedly a bit beyond us, it really seems like while one group is high-fiving that we can deliver drugs directly into cells, another group says, "Shit, this stuff penetrates our cells!"

With such materials already available commercially, it really feels like we haven't done our homework on whether or not our fancy new toys will actually be poisoning our bodies in an irreversible way. Maybe we should take a few steps back before readily adopting even promising materials that we apparently know so little about. [DailyTech]
