Wow, Conventional Milk makes Twins!

Byoliveridley

44m.jpgHoly tentacular twins, Batman! This is crazy news, the first study linking the incidence of twins with environmental factors. The culprit is growth hormone fed to cows to increase milk production. According to this Wikipedia article, a third of all dairy cattle use Monsanto’s rBGH (or rBST) brand Posilac®, so obviously, use is widespread.

FEED – July 2006 (from the Union of Concerned Scientists)

1. Engineered hormone in milk may be linked to twinning. A recent study found that women who consumed dairy products were five times more likely to give birth to twins than vegan women. The study suggested that the use of engineered bovine growth hormone/bovine somatotropin (BGH/BST) to boost milk production in dairy cows may be related to the higher level of twinning. BGH is known to increase twinning in dairy cows. In addition, the rate of human twinning is twice as high in the United States, where BGH is used, as in Britain, where BGH is banned. BGH affects twinning rate by increasing insulin-like growth factor (IGF), a protein produced in the milk of both animals and humans, that promotes ovulation and may help early-stage embryos survive. A separate study found that levels of IGF were 13 percent lower in vegan women than in women who consumed dairy products. Read a press release about the study, which was published in The Journal of Reproductive Medicine.

If true, no woman should ever drink “conventional” milk (non-organic, non rGBH free, etc). Twins are fun, I love my twin nieces very much, but they are much more difficult to carry and deliver, and there are more complications.

Scary, but I suspect this is the tip of the iceberg as far as environmental effects on childbirth are concerned.

  • Asia's brown clouds warm planet

    BBC NEWS | Science/Nature | Asias brown clouds warm planet

    Clouds of pollution over the Indian Ocean appear to cause as much warming as greenhouse gases released by human activity, a study has suggested. US researchers used unmanned aircraft to measure the effects of the “brown clouds” on the surrounding area. Writing in Nature, they said the tiny particles increased the solar heating of the lower atmosphere by about 50%.

    The warming could be enough to explain the retreat of glaciers in the Himalayas, the scientists proposed. The clouds contain a mixture of light absorbing aerosols and light scattering aerosols, which cause the atmosphere to warm and the surface of the Earth to cool.

    Wow, I’ll have to read the paper later today to confirm, but when I was doing aerosol work in India back in the mid ’90s, the Indian Ocean cloud was unknown. 1995 through 1998, there was an experiment called INDOEX (my thesis advisor in Bombay participated in the later phases) which first observed this brown cloud. At that time, it was assumed that the light scattering (hence “cooling”) effects of this aerosol would dominate the absorbing (or “heating”) effects, and initial model estimates seemed to agree.

    Turns out that it has a significant warming effect because the soot particles (dark, therefore heat absorbing) predominate. And, you had to measure it.

    For their study, the team of researchers used three unmanned aircraft, fitted with miniaturised instruments that were able to measure aerosol concentrations, soot amounts and the flow of energy from the Sun.

    The crafts flew over the polluted region of the Indian Ocean at varying heights between 500m (1,640ft) and 3,000m (9,840ft).

    “During 18 flight missions, the three unmanned aerial vehicles were flown with a separation of tens of metres or less and less than 10 seconds (apart), which made it possible to measure the atmospheric solar heating rates directly,” they wrote.

    If true, we can reduce the size of this “cloud” by reducing biomass combustion, installing particle controls on power plants, cleaning up other combustion sources, etc, and reduce global warming effects without worrying that this cloud was somehow mitigating temperature rise as previously thought. So, a win-win!

  • Turning CO2 into plastic?

    Byoliveridley

    Interesting stuff…

    Sifting the Garbage for a Green Polymer – New York Times

    It was here that Dr. Coates discovered the catalyst needed to turn CO2 into a polymer.

    With Scott Allen, a former graduate student, Dr. Coates has started a company called Novomer, which has partnered with several companies, including Kodak, on joint projects. Novomer has received money from the Department of Energy, New York State and the National Science Foundation. Dr. Coates imagines CO2 being diverted from factory emissions into an adjacent facility and turned into plastic.

    Anthropogenic CO2 emissions = 7 Giga ton per year. So it will take a lot of plastics to take care of that. The promise of biopolymers is that they reduce the need for fossil fuels, and are biodegradable.

    Seems to be another case where some funding and regulatory nudging away from the petroleum plastics would really help.

  • Rising Temperatures Affect Indian Crop Yields

    Byoliveridley

    feb-temp.jpgThis story in the Indian Express talks about unusually warm February weather affecting wheat yields in Punjab and Haryana (India’s breadbasket, BTW). This will become more and more common as average temperatures rise from Global Warming. From Lester Brown’s most informative book Plan B 2.0:

    Two scientists in India, K.S. Kavi Kumar and Jyoti Parikh, assessed the effect of higher temperatures on wheat and rice yields. Basing their model on data from 10 sites, they concluded that in north India a 1-degree Celsius rise in mean temperature did not meaningfully reduce wheat yields, but a 2-degree rise lowered yields at almost all the sites. When they looked at temperature change alone, a 2-degree Celsius rise led to a decline in irrigated wheat yields ranging from 37 percent to 58 percent. When they combined the negative effects of higher temperature with the positive effects of CO2 fertilization, the decline in yields among the various sites ranged from 8 percent to 38 percent. For a country projected to add 500 million people by mid-century, this is a troubling prospect

    We might as well accept that this is going to happen and plan
    accordingly. I guess changing the variety would help, so would shifting the growing season a little (I am no crop scientist, so I need to read about this).

    Fishing Major threat to Turtles

    Byoliveridley

    Well, not the least bit surprising, sea turtles have always been very difficult to track, and we’re finally getting verification that, gasp, turtles’ lives cannot be described in simple juvenile = open sea, adult = coast behavior.

    BBC NEWS | Science/Nature | Fishing ‘major threat’ to turtles

    Until now scientists have believed that young turtles live in the open ocean, but change to a coastal habitat when they reach a certain size.

    But researchers working in Cape Verde found that most adults nesting there retain their open water behaviour, with the attendant risk posed by longline boats.

    “The bottom line is that we thought juveniles experienced this risk out in the open ocean with longline fisheries,” said Brendan Godley from the University of Exeter.

    “We thought that if you got them past that, then unless they’re being taken by inshore fisheries, you’re OK,” he told the BBC News website.

    “But now you’ve got adults exposed to longline fisheries, which is very worrying.”

  • Canada – No new coal plants?

    Byoliveridley

    For a minute I thought the pain from playing volleyball last night, plus opening my computer up sleepily at 5:45 in the morning before catching an early bus to work had me hallucinating, but yes, the Canadian federal government actually wants to impose a moratorium on the construction of new coal fired power plants unless they include sequestration (which to me means no new power plants).

    The federal government is planning sweeping new climate-change regulations for Canada's electricity sector that will phase out traditional coal-fired power

    Any new coal plants will have to include highly expensive – and unproven – technology to capture greenhouse gas emissions and inject it underground for permanent storage, Environment Minister Jim Prentice said in an interview yesterday.

    Ottawa also plans to impose absolute emission caps on utilities' existing coal-fired power plants and establish a market-based system to allow them to buy credits to meet those targets, Mr. Prentice said.

    via reportonbusiness.com: Ottawa takes aim at coal power.

    I have a certain distrust for this government, so details are crucial. The right things are being said:

    1. All new plants will need sequestration
    2. A cap and trade to deal with existing coal fired power plants
    3. Phase out of facilities after “fully amortized life” – Not clear on exactly what that means
    4. 90% Emissions free power sector by 2025

    As the article points out, Canada relies on coal much less than a lot of other countries, only 18% of current emissions are from coal, as opposed to the US, where about 40% is from coal.

    So, time to celebrate? Not exactly. Canada’s latest release of 2007 data indicates horrendous performance.

    Canada 2007 GHG Inventory

    Overall, total increase was 6 Megatonnes from 2004 to 2007. But the increases from the Tar Sands were nearly 16 Mt, meaning most of Canada’s other sectors saw decreases, thanks to a number of mild winters and greater efficiency.

    Clearly, this performance is going to continue until the Tar Sands are included in any CO2 reduction strategies, whatever we do, or don’t do with the coal will have a little bit of impact, but will definitely not help Canada achieve any of its short or long term goals.

    So, one cheer for this announcement. I suspect that the administration needs something to take to meetings, and is hoping that a coal moratorium will distract people from the biggest culprits, the Tar Sands and our insanely high per capita GHG footprint. A “no new coal” moratorium would be a huge deal in the States, and off the charts in China or India as far as reducing emissions go. But Canada, not bad, but definitely not good enough!

    The Tar Sands will only be stopped when the US steps up to the plate and gets its Cap and Trade going.

  • Bill to test private drinking water wells under fire

    Byoliveridley

    Ensuring that private wells in  North Carolina are  held to the same standards as municipal water sources seems to be a no-brainer. Why would any one NOT want to know if their primary water source has arsenic, or old lace in it! Apparently, the need to buy a house in one day rather than wait the week or two that most environmental labs in the state would take to run the various drinking water tests takes precedence, seems like a little spin to me.

    The real issue here is the competing needs of the buyer and the seller, the buyer needs to know and the seller does not necessarily want the buyer to know. If this is a private transaction, no big deal, people can ask, but when you’re up against the cookie cutter developers (politically connected, of course) and the home builders association, the power asymmetry pretty much ensures that in the absence of regulation, bad things will happen.

    newsobserver.com | Testing of new wells under fire

    The state’s real estate and home building industries are opposed to mandatory tests of new drinking water wells, especially if a test backlog could delay the sale of a house.

    Companion bills, introduced late last month in the state House and
    Senate at the request of Gov. Mike Easley, would require North Carolina counties to enforce state well construction standards. Water-quality tests will be required of new wells that provide water to houses or small businesses that serve transient populations, such as service stations.

    The News & Observer reported in March that more than 2 million North Carolinians drink water from private wells and that they are at risk from contaminants that they cannot see, smell, or taste. Some are man-made, from a nearby farm or business, and some are natural, such as arsenic or radiological contaminants.

    There are no state testing requirements for private wells. At least three attempts over the past 15 years to require minimal testing have been defeated.

    Rick Zechini, who represents the N.C. Association of Realtors, and R. Paul Wilms, who represents the N.C. Home Builders Association, say the bill should be defeated if it isn’t changed.
    “Until we get assurance that there is [testing] capacity, that the tests won’t take weeks and months, and that the cost is not prohibitive, we’re not in a position to support the legislation,” Zechini said.

  1. Cool, one more thing that I can safely do that a woman. Or wait….does it make a difference if a man drinks the milk and then … you know… does the happy? Dang!

    I’m lactose intolerant anyway, like over 90% of South Indians. I’m glad to just not throw up. I like my coffee without cream, thank you.

  2. Nope, it\’s all on the woman\’s side! Of course, this is not why milk plays such a prominent role in Tamil movies (\”first night\”, anyone!), most Indian milk is hormone free, hormones being a little too expensive.
