Space and more

Its been a busy month. I went to Istanbul on the 24th to give a talk on the media to a group of grid scientists. It was a challenge giving a talk to a roomful of people who were tapping away at their laptops. This, apparently, is what grid scientists do at their meetings. They multi-task by answering emails, browsing the web and listening to presentations. It will probably catch on, so watch out.

Then it was off to the International Astronautical Congress, a wonderful affair in Glasgow this year. From which I filed a piece about the latest developments in the privatisation of space travel.

Related to this I also sent in a green.view about the environmentally critical new bit of space hardware, the Orbiting Climate Observatory.

After this I headed up to visit a company called Oxford Nanopore, which is working on a new way of sequencing DNA. About which, more soon.

Spaced out

Just when things were getting a little dull on the space front, lots of things seem to be happening at once. Politicians have realised that there is a long gap between the retirement of the shuttle and the earliest point that the new system, Constellation, could be flying to the space station. There is talk of trying to close that money with more cash, and retiring the shuttle later than 2010. But this will be politically risky, because the chances of an accident with each shuttle mission are possibly as high as 1 in 75. In any case, at some point engineers have to stop working on the shuttle and start building the new system, there has to be a gap of sorts. Then, just as things couldn't look worse, Russian goes and invades Georgia, scuppering plans to buy Russian transport to the space station in the gap.

We also published a a piece that has been in preparation for a long time, on export controls in the US space industry. Not exactly headline grabbing stuff, but actually crucial if you work in this business.

Space 2.0

Last week I was in Mojave, hearing Virgin Galactic update the world on its progress in creating the world’s first commercial space line. Rolling out of the hanger was White Knight 2. This is a giant new composite aircraft that will loft a spaceship to high altitude. She looked stunning: shiny, colourful and ever-so slightly alien. The work of Burt Rutan’s team at the company Scaled Composites. A lot of work remains. Much testing and firing of engines, followed by flights that get incrementally higher.

As ever, the press unveiling was handled with just a little bit of PR pzazz by the Virgin team. Partway through the press conference, a giant curtain was zipped away to reveal White Knight 2 standing on a bit of airstrip that the press had been walking over just half an hour before. Behind her, perfectly lined up for the press photos, was one of Virgin America’s new planes. The Airbus was called “My other ride is a spaceship”.

There is less progress to report with the spaceship. She was in the Scaled hangar, covered by black dustsheets but clearly unfinished. Although she is 60% or 70% complete (depending on who you speak with) no work has been done on her for the last year. Work stopped after an explosion almost a year ago that killed three engineers and seriously injured three others.

A report on this is imminent, and word has it that work on the spaceship will resume after the report... and that the project will continue with its use of hybrid rockets.

Someone mentioned to me that the team will be modifying the engine to make sure that nitrogen oxidiser in the engine does not flow over composite material at all, only metal parts. I’ve no idea how this could have been involved in any explosion, but if any readers do--you can email me at natashaloder@economist.com

Pesky-cides

On the face of it, writing about European pesticides legislation doesn't appear to be the most fascinating exercise. But this is a subject that is getting everyone very hot under the collar. European legislators want to remove some of the most hazardous substances from use as pesticides--because of their potential to harm people and the environment through misuse. And when they are looking at harm to people, they don't just mean consumers but also the people who apply pesticides.

Such a hazard-based approach annoys lots of people who see this as politics interfering in what was previously a scientific approach. Previously this approach was entirely risk based. A substance can be very hazardous, but in actual day-to-day use pose little risk to anyone because of the way it is used. Conceivably, something that is less toxic, may be harming more people because of the way it is applied (say just before harvest).

In any case, it seems that there is little chance of much change to this legislation when it reaches Parliament for its 2nd reading this year.

A balance of risk. Pesticides keep food edible and cheap. On the other hand they are, by definition, poisonous. Europe’s legislators thus face a dilemma. Jul 3rd 2008

The cost of pesticide tests will go sky high. The market will be handed over to few biggest companies, those which either have some approved pesticides or can afford tests. Did anarchic greens want to create oligopoly of big corporations? Anyway, they did it.

More proof that we base sustainable population calculation on an unsustainable foundation. The common tone expressed is that there is no point in considering any other option. Can the Economist provide more than a window onto Purgatory or Hell?

I agree with Random Scientist. This "prove that this is safe" policy is the same that we have seen in chemicals (REACH) and medicine. In all cases the effect is the same: old and trusted substances are driven from the market because nobody invests to prove them safe and we are left with expensive substances that for many years will stay on patent. And the threshold for further innovation becomes nearly unsurmountable.

I don't understand why the old policy of periodically outlawing the most unsafe substances has become obsolete.

Mine, all mine

The article on June 19th on the endowment effect caused a range of reactions. Some readers thought it was brilliant, others thought it was brainless. The endowment effect is a quirk whereby once someone owns something, he places a higher value on it than he did when he acquired it. I looked at the possible evolutionary origins of this phenomenon in the article:

It’s mine, I tell you, Jun 19th 2008
Mankind’s inner chimpanzee refuses to let go. This matters to everything from economics to law

The reason that the endowment effect still upsets a few people is because it undermines this idea of rational economic man, which has been the core of a lot of economic theory for some years. But behavioural economics and evolution keep chipping away at this idea.

fostercj wrote on June 23 had a different idea for why people keep trying to insist we all act rationally: "That's the endowment effect at work. I'd rather hold on to the theory I've got than trade it even if the new theory is the one I'd have chosen if offered both to begin with. That definitely has some policy implications."

But awinkle on June 22 had a different view: "The endowment effect is NOT irrational. Purchasing items requires time and resources. That is where the added value comes from. If I trade my ashtray for yours, that is a fair trade. If you pay me sticker price for my ashtray, then I have to go out and buy a new one, that is a waste of time for me!table and I'm told to pick one."

Some picked up on the more philosophical aspects of stuff. Genghis Cunn wrote on June 23:
"The Buddha explained the process by which humans develop attachment and craving, a process which with a little training each of us can observe within ourselves."

Along with the article, I co-wrote a jokey leader (op-ed):

Hair raising tales

Going bald upsets a lot of people, mostly men. Everyone looses hair as they get older, but some men in particular loose most if not all of it in what is called male pattern baldness.

Male pattern baldness is the number one reason (when I looked a few years ago) that men are having cosmetic surgery in America. These days a hair transplant doesn't leave you a head like a cheaply woven Chinese doll. No more giant plugs of hair in little plantations, hair is transplanted in tiny, naturally occurring little groups. It is, naturally, very costly. But it works. Hair moved from the back of the head doesn't wilt and die like the stuff that lived on the top. The only problem is that for many men, they simply do not have enough hair at the back of their heads to replace what has been lost at the front and top.

But, you've guessed it, science comes leaping into the room to offer a solution. Intercytex, a Manchester-based company thinks it can create new hair, something described in this week's article in The Economist. Don't get too excited. For whatever reason, the UK authorities have decided that Intercytex's technology is a drug treatment and it must therefore go through trials from phases I to III (it is up to II at the moment). So it will take up to five years before anything appears on the market. But it does offer hope, at last, to the world's baldies.

Drugs bust

Few correspondents liked our leader line on drugs.

Reader William Rising, from Indonesia, wrote in to raise the issues that we didn't delve into, namely how will society adapt to the changes that cognition enhancing drugs and will it be fair for people to take them in competitive situations. These are important questions but difficult to answer without knowing the specifics of the drugs available and how good they really are. We don't worry about people taking coffee or Ritalin at the moment to improve their performance in exams. Maybe we should.

Dr Giorgio Cometto, from London, says that any argument that likens the use of caffeine to the abuse of drugs that are prescribed for a specific person, reflects "a shallowness of analysis that beggars description".

Trying not to be too shallow, I'd like to point out that millions of people use Viagra every day as a recreational drug and nobody really cares because it is largely harmless. The point of the leader was that before getting upset about new psychoactive drugs, we need to bear in mind that many of them may not be harmful and possibly even quite beneficial.

Jil Hellemann from Warwick says that the question really should be about whether the increasing medicalisation of everyday life is a good thing. "You should have questioned the desirability of a society which makes drug usage a predicate to living 'useful' lives and rendering us all disabled".

Similarly Tuure Pitkänen, from Finaland, says that instead of marveling at new medical breakthroughs I should have contemplated why life has become so intensive that one has to consume psychoactive substances to keep up.

Alagbe Taiwo from Nigeria wonders whether students will simply get more lazy as a result of all the drugs available to boost their brains.

And Lynda Cord, from Australia, dislikes the fact that our leader advocates the use of cognition enhancing drugs and wonders if the person who wrote it was working for the drugs industry.

I'm not, and it is highly unlikely that drugs companies will go to the trouble of getting approval for the sale of cognitive enhancers to the general population. Too much trouble. Far easier, instead, to sit back and watch as people decide for themselves that they would like to take these drugs "off label". Off label means using using medication for a condition that has not been approved by the FDA.

Modafinil was approved as an orphan drug (one for very rare diseases) for narcolepsy, yet today has sales in the hundreds of millions of dollars every year. There simply are not enough narcoleptics to support that kind of volume of sales. Everyone knows that off-label use is rife. Nobody is in much hurry to do anything about it.
