The Cents of Military to Energy Alternatives

Think $5.00 a gallon is a high price for gasoline!?! Well we are paying a lot more than that through our health and the environment; and yes, YOU are paying that! It is not just an externality shuffled off onto someone else, but borne onto all America-living, tax-paying households with the additional opportunity costs of investments that could have supported education, health, infrastructure and so on, supporting instead the devaluation of our livelihoods.  The health costs of the U.S. energy policy, are felt across the country, in respiratory and asthmatic conditions, illness leading to missed work days, cardiovascular diseases, cancer, and premature death.  Tailpipe emissions are the largest contributor to health costs from oil as particulate matter contributes “nitrogen oxides, carbon monoxide, and sulfur dioxide” to the atmosphere, all with documented adversities to health.  Realize, that you can sit in a car running in your garage and die.  “Hotspots” where such concentrated exposures overlap with populations of people have grown as urbanization has expanded around many U.S. metropolitan areas.

The National Research Council estimated that oil-driven transportation is costing us approximately $56 billion per year with more than 90% of that estimate linked to the value of life years lost to premature death attributed to air pollution.  Then there are oil subsidies for $4 billion this year and an estimated $46.2 billion over the next decade for an industry that is more profitable than ever!  Such subsidies encourage pollution while discouraging alternatives.  Other costs associated with our oil consumption is through military spending to guard choke-points like the Strait of Hormuz, that over 50% of the world’s supplies must pass through, gobbling up 11-13% of our defense budget ($67.5 billion to $91 billion).  Of our approximately $44 billion monthly trade deficit 62% ($27 billion), of that was for this one commodity alone.  Add to that the multiplier effect of the dollars leaving our economy in the transfer of our wealth for overseas supplies.  For example, such a ripple effect, could generate $1.70 for every dollar spent on manufacturing in the U.S., for service around $1.20  or on infrastructure which could generate around $1.59 for every dollar spent here.

[BusinessInsider.com. “The Stunning Cost Of America's Dependence On Oil”]

Simply switching to electric vehicles isn’t the answer either, when that power is derived from coal.  A Harvard study analyzing the full impact of the life-cycle of coal, from mountaintop removal, processing and combustion, estimates that the American public pays at least $300 billion in health costs and deaths, causing more damage than the value of electricity actually produced, making it a net value-subtracting industry.  These health and economic costs spread onto the American people by polluting energy demonstrate that tax-dollars better spent could be used to power our needs from the sun, wind and water instead.

The above waste on oil and coal alone may not be enough to convert U.S. energy entirely to renewable production, but becomes quite feasible when combined with other inefficiencies that deteriorate our human and environmental resources.  The Department of Defense is ripe with such opportunities! An example is the useless production of C17 cargo planes.  Though there is agreement across the board that the C17 cargo planes are not needed, the program remains due to the strategic gaming of the system that uses the jobs it creates as leverage.  Strategic subcontracts in politically powerful networks and the vulnerability to crony capitalism created by the Department’s lack of transparency, has worked to keep the program in place year after year.

However, green job equivalents for all of the military positions currently on the numerous bases could shift production towards greening our energy.  For example, avionic and aircraft assemblers can become light-rail or electric auto assemblers, industrial mechanics can be wind power engineers and so on.  Simple alternative spending scenarios comparing $1 billion spent on the military, clean energy, health care, education, and for tax cuts to increase consumption, have found that redirecting from the military to the latter sectors, creates substantially more jobs overall.  Specifically, tax breaks would contribute 28% more jobs, clean energy would generate 48% more than in the military, health care 69% more, and education 151% more than what the same $1 billion would produce in military spending.  The 2013 budget proposal allots $525.4 billion in discretionary funding for defense.  This while the U.S. battle fleet is already larger than the next 13 navies combined, 11 of which are allies.  In 2010, the United States invested about $8 billion on green technology while China invests $9 billion… a month.  Under Portugal’s, new clean energy program, wind farms have helped the country move from 17% of its energy from renewable sources just five years ago, to 45% of it today.  Of all these costs to the American people, the most concerning is the human cost to our health and the environment which our future livelihoods depend on.  The vast collective power of U.S. taxpayers could and should be put to more healthy and efficient use.

Stuff White People Like: Other White People’s DNA

In a comment in the journal Nature today, Stanford researcher Carlos Bustamante and others argue that there has been a large bias in favor of people of European descent in genomic sequencing and the Genome-Wide Association Studies (GWAS) that follow.  The story was picked up by other news agencies, such as this article on Wired.

Bustamante points out two differences: the amount of sequencing done on Europeans is greater, and the number of GWAS are vastly more (a whopping 96% are done on groups of European ancestry).  But the astounding latter figure is perhaps less troubling than you might think.

This is because many GWAS can be done on the same data set, looking for genetic associations with  different diseases.  This means that a small bias in the sequencing done to create usable data can lead to a very large bias in the number of association studies performed.  The researchers doing the association studies are simply using the data that are available.  The real target should be to ensure that sequencing is done of more diverse groups, and the association studies would follow.

There is another reason why much of the sequencing effort has focused on Europeans (and East Asians): association studies are more powerful when the population being studied is more uniform.  Populations in East Asia and Europe have had relatively little mixture from outside populations compared to populations in the Middle East or India, and this reduced the chances that such admixture will create a false signal.  The tremendous amount of genetic diversity in Africa and its complicated history of human movements also make it more challenging than studies in Europe.

Bustamante is right to call for more studies of a more diverse sampling, particularly focused on sequencing.  Not only will this help those populations medically, but will have the added benefit of providing diverse data that can help us to understand recent human evolution as well.

CAPTCHAs got you tongue tied and unraveling books one word at a time

Have you ever tried to make an online purchase and just before putting in your payment information, a sudden curvy word, or probably two, appears?

They even do number fractions!

You are asked to decipher what the convoluted word is before you can proceed to make your purchase. You might be surprised to know that these bothersome distractions actually have a name – CAPTCHAs or Completely Automated Public Turing test to tell Computers and Humans Apart. (The Turing test is named after Alan Turing, a British computer scientist.) A NY Times article published in yesterday’s “Science Tuesday” discussed why these CAPTCHAs are so important, even if they seem more of a bother for us consumers. So why are they useful?

  1. It deters hacking. Robots, or more specifically computers, cannot read and interpret the curvy words like humans do, thus a hacker cannot access important information like credit card numbers.
  2. We are helping decode ancient books that were poorly scanned. Although there are recognition programs to decode characters on a page, they don’t account for human and electronic scanning errors. A program called reCAPTCHA is being used to pair a known wavy word (the control) with an unknown previously scanned word to determine the identity of the convoluted letters.

So why was this story so interesting to me? It was something pertinent and applicable to virtually everyone! When reading popular science articles, I often find myself drawn to interesting science stories with the WOW factor. This is a story that doesn’t necessarily have that same appeal, though I found the methodology to be innovative. It is interesting to know that there is some greater use for such a bothersome thing.

Nuclear Reaction

LA Herald Tribute

The crisis in Japan from the accidents induced by the Natural Disasters hitting the Fukushima reactors, has been stirring up reactions here at home. Reactions like Americans buying up the market of potassium iodide pills in fear of radiation reaching California to increasing challenges to nuclear project proposals, such as the recent hearing in Texas by the Nuclear Regulatory Commission.  As John M. Broder recently reported in the New York TimesU.S. Nuclear Industry Faces New Uncertainty” as these events also have government, organizations and even the most staunch nuclear energy supporters backing off from the Nuclear Renaissance, which up til now had been gaining momentum.  This Nuclear Revival comes decades after the Three Mile Island Disaster on U.S. soil in 1979, with Obama’s “$36 billion in Department of Energy loan guarantees for the construction of as many as 20 new nuclear plants”, just last year.  These pressing concerns inciting people to think again about the positions they advocate, make me think about all of the evidence available before the accident that has apparently been disregarded in a movement blissfully engaged around best case scenarios.

The Externalities of Nuclear Power“, by Karl Coplan from Pace University School of Law, analyses the true cost liability of nuclear power, dividing the externalities into terms of risk and waste.  The waste, includes isotopes with half lives of millions of years while the Nuclear Regulatory Commission (NRC) regulations for storage units is set at only twenty years. According to the study,”Several nuclear power plants across the country, including the Indian Point Energy Center just north of New York City, now experience leaks from these spent fuel pools, releasing dangerous tritium, cesium, and strontium isotopes into groundwater and the environment”.   The costs associated are yet to be measured, but ultimately it will be the public to foot the burden of Super Fund clean-ups inevitable considering the nature of the elements.  Along with waste disposal, Copland breaks down the three components of risk externality as: accidental, terrorism and proliferation risks. Accidental risk would include the probability of malfunctions, human error and natural disasters; terrorism is the risk of attacks as a target or theft involving nuclear material and proliferation as the entailing process of advancing nuclear based weapons technologies inadvertently with the use of it for energy.

Copland’s calculations of these external costs found “the value of this “risk subsidy” to the nuclear industry, estimated as high as 30 cents per kilowatt hour”, while in 2009, the average solar costs were 11.5 cents per Kwh (set to steadily decline into the future). To gauge these costs, he references a study by the Riverkeeper organization estimating damages from an accident at the Indian Point Energy Plant just north of New York City, to “exceed $2 trillion in property damage, in addition to 44,000 short-term fatalities and 518,000 latent long-term fatalities” as well as an (NRC) report with similar estimates. So who pays for the costs of these consequences? With liability for nuclear power plants limited to $300 million, and joint industry liability limited to $10billion as of this report (or an even more recent figure of $12.6 billion from KQED’s PBS News Hour on this very evening), much of that cost will not be covered, leaving the lion’s portion of the externalities to be borne by the public.

Imagine if the support, endorsement, money and effort behind the nuclear energy project proposals, was shifted to truly renewable energy; which don’t carry such catastrophic implications of risk and waste. It just seems the logical and responsible direction to take! Rather than subsidizing large monolithic facilities to build an infrastructure of consumerist dependency, why not roll out a mass plan to install solar, geothermal or wind, as it may be fitting per household and region. To instead, use that money to expand current grids to incorporate solar power, covering the difference from such subsidies by continuing the average household energy rates equivalent to what people are paying for their bills now, until the debt is paid and the system starts earning for them; in both efficiency and potential energy sold back to utilities. Not only is this safer and more cost-efficient in the long-run, it also provides independence to Americans, allowing them to support their own needs in the event of any accident, nuclear failure or attack that could cut off people by the masses in a nuclear energy scenario.  My own reaction to this disaster, is an urgent desire to see attention drawn to the true costs of Nuclear Energy; which has too often been dismissed as improbable risk.

Don’t Sit Down!

After my recent experience on a city bus in Berkeley, CA, where I saw a man squeezing gobs of pus out from under his finger nails and smearing it along the metal rail separating my seat from his, and after observing blood in my bathroom sink during an unplanned emergency room visit, my thoughts have been on germs. Thus, I was fascinated when finding this local news story about our regional commuter train system, BART (Bay Area Rapid Transit) – Biologists Find Drug-Resistant Bacteria On BART Seats. This short piece of news, commissioned by The Bay Citizen, briefly describes a study by a San Francisco State University biologist who sampled a random seat from a MUNI train (part of the San Fransisco Municipal Transportation Agency) and another seat from a BART train for bacteria. She found two harmless strains of bacteria on the MUNI seat, which are made of plastic and can be easily cleaned. However, she found at least nine strains of bacteria and two types of mold, including fecal and skin-borne bacteria on the fabric-covered BART seats (all riding for free). The biologist was not able to remove the bacteria from the seat even after she cleaned it with alcohol.

I understand if you are feeling queezy. BART did acknowledge that they need to update their cars, which were designed in the 1970′s, and intended for lower ridership. So given the situation, what do we do? While I am glad this article was published and now we know the dirty truth about some forms of public transportation, no advice was offered in the article about navigating germs in a high-density population. Perhaps it’s time to choose your method of protection when riding public transportation: rain suits over your clothes, protective creams over your body, showers after every ride? It’s easy to become paranoid, especially with the all of the antibacterial propaganda that has flooded the market that makes people feel they are not clean without using antibiotics to wash. But the more antibiotics we use, the more resistant bacteria we create.

It think it’s important to remember that our bodies are pretty good at protecting us, and we are even more protected with a little soap and water. Good old hand-washing is one of the best ways to protect yourself from germs, according to the CDC (Center for Disease Control). Interestingly, this simple act is often neglected as I have personally observed people leaving the bathroom stall and bolting to the door, skipping the sink, in numerous public bathrooms in the US and abroad. A similar thing frequently happens where food is sold. Two weeks ago I was sold a falafel sandwhich from a woman who first took my cash, then began to deep-fry the falafel, then ran back to the cash register to help other costumers while waiting for the falafel to cook. Finally, she grabbed the falafel, threw it on some pita-bread, and added the raw vegetable toppings — all with her bare hands! She handed me the food and smiled. I frowned. No gloves and no hand-washing throughout the entire procedure. We can do better, people. Don’t freak out about germs, and please stay off the antibiotics. Soap and water will do just fine. As for BART, I think their future is in plastics.

Our Tropical Backyard Laboratory

National Geographic has recently featured a series of stories that hit very close to home, in a very far away way. Their Special Report: Island Life Under the Microscope in Mo’orea documents the scientific endeavors currently being undertaken on the tiny French Polynesian island of Mo’orea, including the work being done at UC Berkeley’s Gump Research Station.

A large focus of the series of articles is the Biocode Project, an ambitious scientific attempt to bar code and catalogue the DNA of Mo’orea’s non-microbial biodiversity. It brings together locals and specialists who deal with all sorts of life to try and capture a model ecosystem, establishing a baseline for expected long-term environmental changes.

However, this well-funded project is intended to last five years and thus set to only collect what is found within those five years. On top of that, Mo’orea’s surroundings, chosen as a simplified representation of western Pacific island environments, have already been forced to respond to a range of influences, from invasive species to 1,200 years of human habitation. Despite all this, the undertaking of this ambitious project leaves me with an overall feeling of optimism, if anything as a benchmark for scientific prowess.

This special report sheds light on several of the economic, social, and environmental issues that proliferate Mo’orea’s past and present through use of stunning visuals, video, and articles. (And for a tropical island, what better way to tell a story than with a few vacation slides?) Aside from what I’ve already mentioned, I don’t have much to add to what NG’s feature already offers – I honestly just wanted to share this with you guys, given Berkeley and Integrative Biology’s close ties to the work being conducted there. Cheers!

It’s easy to be polite if you’re a hagfish

“Don’t chew with your mouth open”…no doubt a phrase heard by children at dinner tables across the world (albeit in different languages of course). Parents should lead by example, but now kids have very different role model for good table manners.

Manners aside, with a mouth this lovely, why not show it off?

Over breakfast this morning, which I munched with my mouth close I might add, I read an article about the Pacific hagfish, or the only known vertebrate that is able to take in meals without even opening its mouth! Hagfish are actively uptaking nutrients via outer tissue of the skin and gills…a drastically different strategy than any other vertebrates, which absorb nutrients using inner tissue in the gut.

Okay, so hagfish aren’t quite true vertebrates, instead they are part of a group called notochords. Notochords are highly related to vertebrates however, and their body forms are seemingly more “ancient” by comparison.

Needs a lesson from a notochord...

The  relationship between hagfish and more modern vertebrates means we can learn a lot about the evolution of feeding in vertebrates by studying these organisms. To me, this seems much more lucrative than a learning proper dining etiquette from a hagfish. That’s to say, there are very few “please” and “thank yous” as freshly served dead carrion is passed around the hagfish table, and don’t even hold your breath waiting for a hagfish to put its napkin on its lap.

Now I understand why my husband is jealous of the cat…

This week I read an article in Time Magazine about a study that described the relationships between cats and their owners. The study used videography to record interactions between cats and owners before and after feeding time. Their findings include that cats are adept at getting their owners to give them food and attention and that the owner’s personality is a major factor dictating how the cat and owner interact. The owners found the the cats were particularly good at manipulating female owners and likened the relationship to a mother and her pre-verbal infant.

I decided to that my cat, Obi-Wan, and I should try video-blogging our thoughts on this story. Obi is notorious for shooting my husband dirty looks while he possessively purrs in my lap. Upon watching the video, I think that I agree with the authors of the paper…it’s creepy watching that my cat manipulate me like that!

Here’s our video-blog:

The Times Magazine article ends with a hilarious BBC Comedy clip – even if the research doesn’t interest you, make sure that you check it out!!!
