Owning Hacker As A Word

To a casual observer it might seem as though our community is in the news rather a lot at the moment. It’s all about hacks on our TV screens in the soap opera of Washington politics, who hacked this, whether those people over there helped that lot hack the other lot, or even whether that person’s emails could have been hacked on that server. Keeping up with it as an outsider can become a full-time job.

Of course, as we all know even if the mainstream journalists (or should I refer to them colloquially as “hacks”?) don’t, it’s not us …read more

One of the World’s Strongest Materials Looks Like a Chunk of Coral

It’s made of 3D printed graphene, the ultra-strong and lightweight carbon nanomaterial. And it could be great for building stuff in space. Continue reading One of the World’s Strongest Materials Looks Like a Chunk of Coral

Nylon Fibre Artificial Muscles — Powered by Lasers!

If only we had affordable artificial muscles, we might see rapid advances in prosthetic limbs, robots, exo-skeletons, implants, and more. With cost being one of the major barriers — in addition to replicating the marvel of our musculature that many of us take for granted — a workable solution seems a way off. A team of researchers at MIT present a potential answer to these problems by showing nylon fibres can be used as synthetic muscles.

Some polymer fibre materials have the curious property of increasing in  diameter while decreasing in length when heated. Taking advantage of this, the team …read more
