A natural boost for MRI scans

New article!

EPFL scientists have found that pyruvic acid, a glucose metabolite, can be used for high-contrast MRI scans instead of that scary, free radical-ridden stuff they usually inject you with to get your protons jumping (aka hyperpolarising agents). Soon we’ll be MRI-ing recreationally. It’s the dream.

Bits & Pieces: They come to me

You might not know this, but I write. A lot. And like many writers, I often write experimentally. Try things out. So I have this folder on my computer labelled “Bits and pieces”. It contains short bouts of stuff I’ve written either for fun/expression, either to try out a new style, or even as a part of a future novel. They’re not complete. They’re not short stories. But instead of letting them collect digital cobwebs, I thought I’d polish the occasional piece and share it on the blog. So here’s one. Make of it what you like.

They come to me. From all over, I see them drawing near, like ants on a dead rat. From where I stand, I can see them coming for miles – little lines of humanity’s leftovers, small, sad, tepid ghosts dragging the chains of themselves behind them. It’s what’s left of us. It’s what we left for ourselves. And now, on that endless pursuit for meaning, this human detritus still gets on its feet and shuffles over to the mountain, the one landmark over a charred landscape.

They come over and stand at the foot of the mountain, looking up. They don’t know, they just feel for now. It’s rational bypass now, all gone, the logic, the analysis, the mind, the what-got-us-here, it’s just instinct of the basest kind, homing on some rock protrusion in a flat horizon, something different in the nothing that surrounds us.

They look up, watching me. And I look down, watching them. It’s not mercy, or grace. It’s not the pursuit of meaning, happiness or anything like that. It’s just a gaze. Eye contact. Species recognition. Acknowledgment between the damned.

In the grey sky, the light slowly collapses. Dusk. Night. No stars. No moon. Just the dark and the land spreading at my feet, twinkling now with a thousand little fires and tiny dark figures huddling quietly around them.

It’ll be cold tonight. It’s cold every night.

It’s all we have left.

Using heat to make magnets

New article!

Scientists at EPFL provide the first ever experimental evidence that a magnetic field can be generated by a temperature gradient. Why is that important? Because it might change the way we do electronics. And can also give a purpose to all those overheating laptops.

Read more here.

Burglary update: They’re not catching anyone. I’ve made my peace with my stolen laptop. I’m now shopping for a new one. It’s OK. Don’t have to eat food every day.

Many thanks for the moral support, everyone! Your comments here and on Facebook/Twitter prove that the Internet can be used for good. You guys rock.

I promise to get back to drawing ASAP.

Why do astronauts on the ISS feel weightless?

Hi everyone,

I have a new Science Q&A on the EPFL website today, which I have subtly marked on the screenshot below:

Sans titre-1So far, the majority of readers are picking wrong answers.

Give it a shot!

Short story: Fired

The three of them sit in a semicircle, the Director in the middle, HR to my left and my line manager to my right. Door behind me. Window across, dark with the March dusk and a miserable rain pattering on the double-glazed, soundproof, insulating, corporate glass.

Nature doesn’t usually mark the occasion. Babies are born during hurricanes. Lotteries are won in a blizzard. A guy jumps out of the twentieth floor of his apartment building on a sunny-blue summer day and sprays the warm sidewalk with his brains while seagulls fly above.

Nature doesn’t care.

Someone’s talking and my employee-conditioning kicks in and I pay attention. The Director’s pudgy face contorts in a semi-sad smile and his mouth kickstarts the stage play we are about to engage in by invoking the first line of his managerial script.

“How are you feeling?”

Of course, honesty isn’t expected. Bound by the pseudo-social contract of professional interaction, I also smile sheepishly and mutter something between “okay” and a verbal shrug.

Phase one is over and it’s time for his soliloquy. He speaks in the measured, paced, practised and soft tone of the veteran manager, but when I look up from the table and catch his eyes, all I see is autopilot.

He uses a lot of filler. Words like “performance”, “output”, “competence” and “leverage” fill the air between blow-softening neutrals like “expected”, “observed”, “discussed” and “decided”.

I nod to the music, but I can’t help keeping one eye on my watch. It takes him forty-seven seconds to go through the obligatory spiel, to put me at ease, to avoid conflict, to prevent negotiation, to minimise the chance that I’ll come back tomorrow with a case of home-made Molotov cocktails.

I feel tired. Forty-seven seconds, and then he finally gets to it.

“We all think that it would be better for you to not continue in this role.”

And just like that, the ritual – and my job – is over. Of course, there’s still some epilogue, but the main story has ended. Some live happily ever after. Some others, not so much.

They are expecting some reaction from me. For a moment, I entertain the idea of saying nothing and just staring impassively out the window. Lack of affect. Psychopathy. Scare them a bit. But then that “burn-no-bridges” instinct overcomes me, so I sigh a little and throw on fake stoicism. “Well, some things just don’t work out.”

They all nod, relieved. Whichever of them writes the report on this, they’ll tick the box that says I took it well.

The HR lady rattles off some information about contracts, final payments and paperwork. Then the Director looks at me with managerial puppy eyes and asks, “Is there anything you’d like to say?”

Like that’d make any difference. But I guess they give all the condemned a chance to final words, so I blather something that doesn’t exactly blame Management, but doesn’t exactly absolve them either.

They feel it. My line manager – ex line manager – looks uncomfortable.

Well. At least he’ll have a job tomorrow.

The rest goes fast. They get on with the scripted noise about how they wish me well and that I’ll probably have questions in the next couple of days and shouldn’t hesitate to email them.

Then they take my staff ID card. Of course, they deactivated it before the meeting even started.

The Director stands up and then the rest of us do. I breathe through my nose as my ex line manager storms out of the office without even saying goodbye.

The Director walks me out of the building and tries to pass it off as being friendly. It’s not. Company policy dictates that he has to escort me off the premises. Not a bad idea, actually.

Before I know it, I’m in a taxi on my way home. Five pm, on a rainy Tuesday. When I get home, I don’t turn on the lights. I lock the door behind me, walk into the lounge and sit quietly on the sofa, listening to the rain outside.

For the first time in my life, I’m fired.
