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).

Physicists Just Discovered a New Form of Light
A new form of light, one where the angular momentum of each photon takes only half of the value of Planck’s constant, has just been uncovered.

It’s easy to take light for granted and assume that we know everything there is to know about it—after all, it’s everywhere. But as it turns out, we might have only scratched the surface.

Today, physicists announced that they have discovered a new form of light. It’s completely different from our existing rules regarding light and angular momentum, showing that light can take on new and unexpected forms, and these could fundamentally change our current understanding of electromagnetic radiation.

  • Me: *in a pub with an Irish friend of mine*
  • Irish Friend: Fancy another pint?
  • Me: Always!
  • Irish Friend: Ha ha, grand. You're gas.
  • Me: I'm what?
  • Waiter: *drops a glass*
  • Irish Friend: Oi, your man there is such a feckin' eejit.
  • Me:
  • Irish Friend:
  • Me:
  • Irish Friend:
  • Me:
  • Irish Friend:
  • Me: I have a question, and I cannot overemphasize how seriously I'm asking.
  • Irish Friend: What's that?
  • Me: Do you think we're speaking the same language right now?

So my college are currently doing this ‘Jailbreak’ thing where you have like 48 hours to get as far away from college as you can with no money and you’re supposed to get airlines and stuff to sponsor you and raise money for charities

and there are people in like Austria and stuff, which is cool

but there’s this one team

who went to Dublin airport


talked to him
