View from the AAAS Conference in Chicago

A couple of weeks ago I attended the American Association for the Advancement of Science Conference in Chicago. It was my first conference of that size, and the first time I have gone as a journalist, and not a participant.

It is cold in Chicago in February, the lake was frozen for as far as you could see, with sheets that had broken off at some point rising out of the flat desert landscape on the water. It looked a bit like there had been a landslide or earthquake, with the plates sliding above each other.

It has been a harsh winter in general here, and Chicago had experienced some of the coldest temperatures in decades, I found this photo below on the Huffington Post site.

In the background we see the Chicago skyline, and the conference was held in one of the giant hotels that looks out over the lake. There are many hotels on the shorefront, and one thing that surprised me is that they are all linked together by a series of underground tunnels.

Tunnels is a bit of a misrepresentation really, they are underground streets, with shops and bars and sign posts, so that on a cold winter’s day guests do not have to step outside. The conference made use of several different hotels and restaurants, and some people told me that although attending different venues they had not in fact been outside, and had not put on a jacket since their arrival.

The system is known as the pedway, see an explanation here, it covers 40 square blocks. The photo below gives an idea of what parts of it look like. Apparently they are not uncommon in North American cities, in Montreal it is known as the underground city.

As I said above the conference was a giant affair as the program demonstrates. I wanted to see a session on responsible innovation and to take part in the launch of the Journal for Responsible Innovation (I am on the Editorial Board and the Bassetti Foundation sponsored the event) but at any one moment there were dozens of panels in session and associated events.

The journal launch clashed with a talk given by Alan Alda the American actor (most famous for his part in MASH). Alda now runs The Alan Alda Center for Communicating Science where he addresses issues and trains people in the art of science communication.

As I said I couldn’t attend but many of my colleagues told me that his talk was great.

I attended a session called Responsible Innovation in a Global Context early on Saturday morning. It was a great session and I learned a lot. Did you know for example that all research that is conducted involving water has to use an internationally accredited water? Yes it is purified water that then has certain amounts of certain minerals added. This means that scientists doing research in Brazil are using identical water to those conducting research in Italy, or Australia or anywhere else for that matter.

Great we might think, but using this type of water also makes some of the research useless. If bacteria lives in a river it interacts with its own type of water, plants life etc and reacts in particular ways. In the official water these reactions are not seen, so the research does not replicate a real life situation, so the results are different to the real experience.

But in order to get funding and to have their research accredited only one type of water is allowed. So money is spent on research that does not represent reality because “that is what the funding bodies want”. A ridiculous situation it would seem.

The influence of politics in research was also addressed from a Brazilian perspective, but one that can be applied throughout the world. When research and innovation is so tied to politics and touted as the saviour of the economic decline or development of a country it sometimes takes on a nationalist hue. This leads to questions about by whom, for whom and with which goals, that involves ethics and responsibility.

One of the most interesting developments though involves collaborations between the hard and social sciences. In several areas social scientists have been placed within science labs to act as a forum that allows scientists to talk about and understand the ethical dilemmas that they face while carrying out their work.

Much of the stuff I write about is related to the problem of scientific development and dual uses, unforeseen effects and changes they bring about in society, and having a social scientist, philosopher or ethicist in the lab seems to open up debate and even effect scientific outcomes. It might even seem to improve productivity is some ways!

As an aside I should add that attending a conference as a journalist has many advantages. As a participant you want people to listen to you, you have to pay to attend and publicize your event. But as a journalist everyone wants to talk to you so that you will write about them.

At every chance organizations try to engage you. There are free cooked breakfasts offered by national research councils, aperitifs form journals and unions, awards, free books and cd’s more alcohol, cakes and coffee, nights out with transport laid on, more food and more alcohol. Many of my colleagues were jealous, they had to pay for everything.

Thousands of people attended the conference and a lot of networking took place. I get the impression that this is really what these large conferences are all about. I am pleased to report that science bloggers (such as myself) are taken seriously and accepted as serious journalists, and there were many of us sitting alongside Reuters and the New York Times. All Kudos to the AAAS for that.

I stayed at the Palmer house hotel in Chicago, a splendid structure and once the largest hotel in the world. Worth a stay or even just a look if you are passing through. Other famous guests include Mark Twain, Oscar Wilde, Charles dickens and the scarecrow from the Wizard of Oz, so I won’t be asking for a plaque to be erected about my visit.

Get ready to rewrite the laws of physics!

At the end of last week the news broke that scientists at Cern believed they had managed to send subatomic particles faster than the speed of light! This was big science news, and potentially big technology news in the future, however I choose not to write about the discovery straight away, as I wanted to find out as much as I could before reporting back to you.

What happened?

So what basically happened last week was that scientists in Cern (Switzerland) who have been blasting neutrinos (subatomic particles) 732km all the way to Gran Sasso (Italy) for a good few years now, collated all their data, and found that it would actually appear that the neutrinos arrived at Gran Sasso when light was still 18m away Basically the neutrinos raced light 732km and won by 0.00000006 seconds –  or as you could also say, 60 nanoseconds.

Is this true?

Scientists at Cern would tell you that their research has been checked and double checked, therefore what they have found out is true as they can’t seem to find a flaw in the research. However at the same time, almost any good physicist, and no doubt scientist working on the project would tell you that it can’t be true and that a variable must have been overlooked, as the results are impossible!


To verify the findings, two similar projects one in Hida (Japan) and the other in Chicago (USA) are attempting to recreate the experiment, and should have reliable enough results, hopefully, by some time next year.

Why is this important that the neutrinos travelled faster than the speed of light?

Einstein said that it was impossible to travel faster than the speed of light. If you like, light was the universal speed limit, no faster could anything ever go than light, you could go as fast, but not faster. This would mean that to get to the sun, (not that you would want to) the quickest you could ever do it would be in 8 minutes and 12 seconds.

The Sun

It takes around 8 minutes and 12 seconds for the light from the sun to reach earth

If the results from this experiment are correct, with some extra thrust, it would be possible for the neutrinos to get there even faster than light could.

How have they ‘broken the speed limit’?

You may be wondering how the neutrinos managed to get to Gran Sasso faster than light, and as are many scientists! There are two main theories of how they did it at the moment.

The first theory is that the speed of the neutrinos was so great they were simply able to travel faster than light.

The second, much more interesting theory is that the neutrinos didn’t exceed the speed of light, but instead dimension jumped! This means that they probably didn’t travel faster than the speed of light, just used another dimension to get from Cern to Gran Sasso.

The Doctor's TARDIS

The Doctor’s TARDIS (from Doctor Who) travels in time and space, this is only possible if you can either go faster then the speed of light, or jump dimensions

Physicist Brian Cox has an excellent explanation of how this could potentially work. When talking about extra dimensions he has said that:

“…if they are right, then things can take short cuts through the extra dimensions. It’s just like saying there is a speed limit that stops you going, lets say you go from London to Sidney, so you fly around the earth from London to Sidney, but the other way to do it, is go through digging a big tunnel, straight through the earth and that’s a shortcut. So in some ways, extra dimensions can behave like that, so what could be happening is the neutrinos could be taking a shortcut thorough another dimension.”

If this were right, then Einstein’s theory of special relativity wouldn’t be violated, just only valid in three dimensions.

What next?

The data is now out there on the net, for all scientists to analyse. Also, there are many places that are going to try and replicate the stud, to prove or disprove the results.

Hopefully we will have some more news soon, as to whether we actually can get things to travel faster than the speed of light, and as to whether there are are more than three (four including time) dimensions!

Anyone else slightly excited by this? 😀
