Graphene-spiked Silly Putty picks up human pulse
'G-putty' is so sensitive that it can track even the steps of a small spider.

A dash of graphene can transform the stretchy goo known as Silly Putty into a pressure sensor able to monitor a human pulse or even track the dainty steps of a small spider1.

The material, dubbed G-putty, could be developed into a device that continuously monitors blood pressure, its inventors hope. It also demonstrates a form of self-repair that may herald smarter graphene composites.

Since graphene was first isolated in 2004, researchers have added these atom-thin sheets of carbon to a panoply of different materials, hoping to create composites that benefit from its superlative strength and electrical conductivity. But there have been surprisingly few attempts to blend it with ‘viscoelastic’ materials such as Silly Putty, which behaves as both an elastic solid and a liquid. Leave a lump on top of a hole, for example, and it will slowly ooze through.

Conor Boland, a researcher working in Jonathan Coleman’s nanotechnology lab at Trinity College Dublin, wondered what would happen if he brought the two materials together. “I’d like to be able to say it was carefully planned, but it wasn’t,” laughs Coleman. “We’ve just got a tradition in my group of using household stuff in our science.” (In 2014, his team found that they could make graphene by blitzing graphite in a kitchen blender2).

I've found what really makes you crank up your stereotype level is living somewhere other than Ireland. When I go home I'm grand but in England I practically snort a leprechaun, throw shamrocks at everyone and leave this plane to become a potato and I've no idea why.

I think it’s a real determination to hold onto your identity when you’re somewhere unfamiliar. I definitely found that when I moved to the city my unspecified Munster accent got stronger the longer I stayed. 

Funny Irish Slang Entry #2

I’m far overdue for another one of these, so without any further delays, I give you more funny Irish slang:

  • Banjanxed: if something is banjanxed, it’s broken, generally beyond repair.
  • Craic: I hear this word used almost as much as “grand” and in a myriads of contexts. It’s the Irish word for “fun”, so you’ll often hear people say “It was good craic” or “the party was craic”. However, it can also be used as a greeting: “What’s the craic?” which really just means “What’s up?”
  • Post: It’s not mail, it’s post. This is packages and physical letters.
  • Mail: e-mails. Yeah, you can bet these two were confusing at first.
  • Fizzy drink: soda or pop. They also use the term Coke as a blanket term for all sodas.
  • Culchies: this is what city folk call the people from the country.
  • D4s: People from a preppy part of Dublin. They are apparently despised for the way they dress and their general snobby attitude.
  • Purse: Okay, now this one has gotten me in trouble before. Here, only men carry wallets. A woman’s wallet is her purse, and her purse is her handbag. I have gotten into actual arguments with people where they insist my wallet is my purse, and I insist it doesn’t freaking matter.
  • Queue/Q: the line you form when waiting. “There’s a queue for the loo.”
  • Till: cash register.
  • Cén fath: Irish. It means “why”. Don’t ask me why people bother to say this. It was an extremely Irish person who said this to me.
  • Cula Bula: Not Irish at all, make no mistake. This is just a phrase that means “Great!” The same guy I mentioned above said this to me.
  • “I’m going to head”: Irish people aren’t going to leave or dip or peace or any of the things we say. When they’re departing, they’re going to head.

That ought to be enough for now. Expect at least one more of these.
