Top Scientific Breakthroughs of 2009 57
Wired has posted their favorite scientific breakthroughs of the past year. The feats include things like the confirmation of element 114, a cancer-detecting breathalyzer, the power of jellyfish and more. What other discoveries should have made the list and what might we look forward to in 2010? "Also this year, researchers at the University of Washington cured two adult monkeys of colorblindness by giving them injections of a gene that produces pigments necessary for color vision. After the treatment, the animals scored higher on a computerized color blindness test. In the coming years, gene therapy will be tested as a remedy for all sorts of inherited diseases, cancer, viral infections and even high cholesterol."

Re: (Score:3, Informative)
The US has had a long history of being overly conservative on automotive equipment. A classic example is the amount of time that passed before aerodynamically shaped headlights were allowed on cars in place of flat faced sealed beams. Ever wonder why the headlights on a car such as this Mustang SVO [wikipedia.org] or this Mercedes S-Class [wikipedia.org] don't blend into the rest of the front end? Silly laws are why.
The fact that these aerodynamic lights performed their function correctly was irrelevant... they were different in form,

Re:Non-reversing mirrors! (Score:4, Informative)
I don't know the original intention of the legislation, but I use the driver side mirror for its intended purpose -- to remove the blind spot when changing lanes or turning right. I position it so that if a car is passing me on the left, I can see it leave the view of the rear-view mirror and enter the driver side mirror, until I can see it with peripheral vision. I usually have the driver side mirror angled way out.
There isn't a reason (to me) to see more with that mirror; if I could see cars further to the left of me, it would only be confusing when trying to switch lanes quickly. (Is that car immediately left of me, or is it two lanes over?)

Side mirrors are used for reversing too (Score:1)
... as a driver who started driving utility vehicles shortly after getting his licence, I can attest to the fact that the side mirrors are invaluable for reversing a loaded ute (or car/truck for that matter) into tight spaces. Perhaps the intention is not to distort the field-of-view when they are used for this purpose?

With a mirror in TFA, you see more of the road surface as well, which means you see the lanes.
Also, curved mirrors aren't usually used for driver-side - as you point out, driver-side mirrors are generally good enough as it is. But on the other side, it can be handy to see more, especially to spot those pesky bicyclists who love to charge past cars on the right, and when parking.

Convex mirrors make objects appear further away.
The passenger side mirror is generally a convex, wide field of view mirror, inscribed with the famous warning "objects in mirror are closer than they appear."

That one appears to just be a convex mirror. You can easily get one. In fact, there's probably one on the passenger side of your car right now.

The answer to the question, why do mirrors reverse left/right and not up/down is simple: they do neither. A few seconds of ray tracing show that they reverse front to back.

Somewhat, but not the way many people seem to. The first time someone pointed out that "ambulance" was written backwards on the front of an ambulance, so that people could read it in the rear view mirror, I thought they were joshing me... even while I was looking at it.

Seriously if you want to get an idea of just how horrifyingly good google is at data mining and pattern recognition create a gmail account and observe how little spam you get. Then check the spam folder and search it for false positives.
The only spam I get nowadays is things I have deliberately signed up to but neglected to unsubscribe from because I'm too lazy.

Prebiotic Ribonucleotides (Score:5, Interesting)
With all due respect to the achievements heralded in the Wired article, the scientific paper that most blew me away in 2009 was Synthesis of activated pyrimidine ribonucleotides in prebiotically plausible conditions by Powner et.al. in the 14 May 2009 issue of Nature. The authors demonstrated an efficient synthesis of a phosphorylated ribonucleotide under mild conditions using only a small number of simple molecules likely to have been present in the "pre-biotic soup" of early Earth. The reaction is so facile that it would be surprising if it didn't occur given the presence of these molecules (cyanimide, cyanoacetylene, glycolaldehyde, glyceraldehyde, and inorganic phosphate). Because the products are activated ribonucleotides, they would have readily polymerized into something like RNA and quite probably the first self-replicating molecule.
To me this was one of the biggest "missing links" in the story of how life might have arisen from simple organic molecules, and that scenario now seems like a slam-dunk. The rest, as they say, is history...
