Hacking Democracy

HBO recently aired a documentary entitled Hacking Democracy which looks at the secrecy surrounding electronic voting machines in use within the US, particularly those manufactured by Diebold; how do the machines work, how are votes counted, how are they audited and why is the whole process so secret?

It follows a group of concerned citizens as they try to break through the veils of secrecy and figure out exactly what is going on with these machines, and uncovers some ugly incidents: Gore being counted a total of -16,000 votes (yes, minus votes) in 2000, differences between official ‘on-the-night’ audit trails from Ohio 2004 and those published later, and those official trails ending up in the garbage; the official record of the public’s vote being deliberately thrown out?? It closes with a demonstration of how easy it is to fix an election by pre-loading votes onto the memory card before the election starts. The voting machine doesn’t pick up any tampering and duly certifies a rigged election.

Although it’s 1h20m long, this doco is well worth a look as a testament to what basically the death of democracy in the very nation which proclaims itself the greatest democracy on the planet.

Cool Science

Every now and then a science article will throw up something that I think is brilliant. An article in today’s Seed, entitled The Wiring of Desire, contained one such nugget.

After discussing how temperature affects sexual selection in developing gecko embryos, and how it also affects later behaviour, the author goes on to mention similar effects on other species:

It turns out that an embryo’s environment has similarly powerful effects in other species. Mice, for example, give birth to more than one pup at once — and the behavior of adult mice is affected by whom they were next to in the womb. A female who was between two sisters is more docile as an adult, and males tend to find her more attractive than other females. She is also more likely to be attacked if she rejects a male’s advances. A female who was sandwiched between two brothers will be more aggressive—and less attractive to males.

I just like it because it illustrates the fluid nature of everything in nature. It’s not simply a case of different, precisely controlled, doses of testosterone for male and female, but a general increase of testosterone in the area around embryonic males which then also raises levels in any surrounding females.

Co-operation In Slime Molds

The Loom as an interesting post discussing co-operation and cheating amongst slome molds:

After several hours, the Dictyostelium slug goes through another change. The back end catches up with the tip, and the slug turns into a blob. About 20 percent of the cells move to the top of the blob and produce a slender stalk. In order to keep the stalk from flopping over, these cells must produce rigid bundles of cellulose. Unfortunately, this cellulose also tears apart the amoebae that make it. The remaining amoebae in the blob then take advantage of the suicide of their slugmates. They slide up to the top and form a globe. Each amoeba in the globe covers itself in a cellulose coat and becomes a dormant spore. In this form the colony will wait until something – a drop of rainwater, a passing worm, the foot of a bird – picks up the spores and takes them to a bacteria-rich place where they can emerge from their shells and start their lives over.

If a particular mold can avoid becoming part of the stalk it could gain an evolutionary advantage, but as you would expect there are checks and balances in place to detect cheating. The rest of the article looks at the latest research on the topic and is worth a read.

Terrorism Paper

The Caot Institute has a paper titled A False Sense of Insecurity (97KB PDF) which looks at the real risks associated with terrorism and compares them to risks encountered in everyday life.

Until 2001, far fewer Americans were killed in any grouping of years by all forms of international terrorism than were killed by lightning, and almost none of those terrorist deaths occurred within the United States itself. Even with the September 11 attacks included in the count, the number of Americans killed by international terrorism since the late 1960s (which is when the State Department began counting) is about the same as the number of Americans killed over the same period by lightning, accident-causing deer, or severe allergic reaction to peanuts.

Kind of puts it all in perspective really. And for this the US has spent almost a trillion dollars on wars in Iraq & Afghanistan? Sounds like a complete waste of money to me… unless, could it really all be about oil?? ;-)

The article also makes the point that we are letting the terrorists by becoming unnecessarily worried and that our governments, particularly the US Government, are deliberately inflaming public opinion:

What is needed, as one statistician suggests, is some sort of convincing, coherent, informed, and nuanced answer to a central question: “How worried should I be?” Instead, the message the nation has received so far is, as a Homeland Security official put (or caricatured) it, “Be scared; be very, very scared — but go on with your lives.”

Or, as John Howard likes to say, “Be alert, not alarmed”. However, while this approach would be admirable, and certainly preferable to the current one, it would probably fail as the general public has an inability to understand relative risk. The article notes that an American’s odds of dying on an airline flight is around 1 in 13 million. You would get the same odds in a car, on the safest roads, after only driving 11 miles! Worth a read.

Geopolitics

Juan Cole, and one of his readers, have come up with a theory of what is really going on in the Middle East, and it all centres on Iran’s oil & gas reserves.

In a worst case scenario, Washington would like to retain the option of military action against Iran, so as to gain access to its resources and deny them to rivals. If Iran gets a nuclear weapon, however, that option will be foreclosed. Iran may not be trying for a weapon, and if it is, it could not get one before about 2016. But if it had a nuclear weapon, it would be off limits to US attack, and its anti-American regime could not only lock up Iranian gas and oil for the rest of the century by making sweetheart deals with China. It also might begin to exercise a sway over the small energy-producing countries of the Middle East. (The oil interest would explain the mystery of why Washington just does not care that Pakistan has the Bomb; Pakistan has nothing Washington wants and so there was no need to preserve the military option in its regard.)

Even an Iranian nuke, of course, would not be an immediate threat to the US, in the absence of ICBMs. But the major US ally in the Middle East, Israel, would be vulnerable to a retaliatory Iranian strike if the US took military action against Iran in order to overthrow the regime and gain the proprietary deals for themselves.

In the short term, Iran was protected by another ace in the hole. It had a client in the Levant, Lebanon’s Hizbullah, and had given it a few silkworm rockets, which could theoretically hit Israeli nuclear and chemical facilities. Hizbullah increasingly organizes the Lebanese Shiites, and the Lebanese Shiites will in the next ten to twenty years emerge as a majority in Lebanon, giving Iran a commercial hub on the Mediterranean.

China and India could get Iran, and Iran could get Lebanon, and as non-OPEC energy production decreases, the US and Israel could find themselves out in the cold on the energy front.

Never trust another US election

From The Open Voting Foundation:

“Diebold has made the testing and certification process practically irrelevant,” according to Dechert. “If you have access to these machines and you want to rig an election, anything is possible with the Diebold TS — and it could be done without leaving a trace. All you need is a screwdriver.” This model does not produce a voter verified paper trail so there is no way to check if the voter’s choices are accurately reflected in the tabulation.

Brilliant!

This is brilliant:

To see him speed down hallways and make sharp turns around corners is to observe a typical teen – except, that is, for the clicking. Completely blind since the age of 3, after retinal cancer claimed both his eyes (he now wears two prostheses), Ben has learned to perceive and locate objects by making a steady stream of sounds with his tongue, then listening for the echoes as they bounce off the surfaces around him. About as loud as the snapping of fingers, Ben’s clicks tell him what’s ahead: the echoes they produce can be soft (indicating metals), dense (wood) or sharp (glass). Judging by how loud or faint they are, Ben has learned to gauge distances.

The technique is called echolocation, and many species, most notably bats and dolphins, use it to get around. But a 14-year-old boy from Sacramento? While many blind people listen for echoes to some degree, Ben’s ability to navigate in his sightless world is, say experts, extraordinary. “His skills are rare,” says Dan Kish, a blind psychologist and leading teacher of echomobility among the blind. “Ben pushes the limits of human perception.”

Global Warming

RealClimate has an article up discussing potential tipping points in our climate which, among other things, elaborates further on Jim Hansen’s ‘ten years left’ comment:

The ‘10 year’ horizon is the point by which serious efforts will need to have started to move the trajectory of concentrations away from business-as-usual towards the alternative scenario if the ultimate warming is to stay below ‘dangerous levels’. Is it realistic timescale? That is very difficult to judge. Wrapped up in the ‘10 year’ horizon are considerations of continued emission growth, climate sensitivity, assumptions about future volcanic eruptions and solar activity etc. What is clear is that uncontrolled emissions will very soon put us in range of temperatures that have been unseen since the Eemian/Stage 5e period (about 120,000 years ago) when temperatures may have been a degree or so warmer than now but where sea level was 4 to 6m higher…

Scientific American has a blog post which tackles one of the common global warmign skeptic srguments, namely that the present warming could be a natural uptick. It examines all the different sources of evidence for global warming and explains why the current warming is almost certainly man-made and not a natural uptick. Well worth a read, simply to give you an idea of the depth of evidence. It’s also part of a series of articles dealing with common themes of global warming skepticism, so it’s worth reading the other articles in the series too.

Interesting

The Bush administration tried to prevent Jim Hansen, Director of NASA’s Goddard Institute for Space Studies, talking to the press about climate change but the plan backfired. Here he gives his expert opinion on the global warming debate in the New York Review of Books, including this alarming warning:

As explained above, we have at most ten years — not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions. Our previous decade of inaction has made the task more difficult, since emissions in the developing world are accelerating. To achieve the alternative scenario will require prompt gains in energy efficiencies so that the supply of conventional fossil fuels can be sustained until advanced technologies can be developed. If instead we follow an energy-intensive path of squeezing liquid fuels from tar sands, shale oil, and heavy oil, and do so without capturing and sequestering CO2 emissions, climate disasters will become unavoidable.

An article in Scientific American details the latest research on how supervolcanoes form and erupt, and how their eruptions can have long term effects on the atmosphere.

The oxygen 17 excess and other chemical patterns that we found in sulfate from the Yellowstone and Long Valley ash samples thus implied that significant amounts of stratospheric ozone were used up in reactions with gas from the supereruptions in those regions. Other researchers studying the acid layers in Antarctica have demonstrated that those events, too, probably eroded stratospheric ozone. It begins to look as if supervolcano emissions eat holes in the ozone layer for an even longer period than they take to cool the climate.

This loss of protective ozone would be expected to result in an increased amount of dangerous ultraviolet radiation reaching the earth’s surface and thus in a rise in genetic damage caused by rays. The magnitude and length of the potential ozone destruction are still being debated. Space observations have revealed a 3 to 8 percent depletion of the ozone layer following the 1991 eruption of Mount Pinatubo in the Philippines. But what would happen after an event 100 times larger? Simple arithmetic does not solve the problem, because the details of atmospheric oxidation reactions are extremely complex and not fully understood.

A surgeon answers the question ’What’s it like to cut in to somebody?‘:

Nowadays, routine surgery, such as breast biopsies or other elective surgery, it doesn’t even raise my pulse anymore. But I never forget that, society has granted me and relatively few others the privilege to cut into living human bodies legally in order to try to cure them of disease. I like to think that I’ve earned that right through my skill, but it could just as easily have gone the other way.
