Scientists Discover Compound In Baby Diapers Can Enlarge Brain Cells

An anonymous reader writes with news of a breakthrough in brain imaging thanks to a compound found in diapers. "A team of researchers has discovered that a compound used in baby diapers to absorb the liquids can help enlarge the size of the brain cells for a better imaging. The scientists work at the Massachusetts Institute of Technology and were experimenting with new ways that could help them enlarge the brain cells for a better resolution photos. They discovered by accident that sodium polyacrylate, a compound in baby diapers can enlarge brain cells and can be used in their research. The scientists termed the new technique of enlarging the brain cells 'expansion microscopy.' This new technique will help the scientists increase the brain cells tissue samples and see it in a better image resolution."

    Being close contact with diapers, how this chemical might be effecting babies ?

    The chemical is basically a harmless salt not too different from sodium chloride (Unless you were to start eating quantities of it), and there is not a large amount of it in a diaper, so obviously the chemical is specifically used for its beneficial affects.

    Use of the chemical improves sanitary conditions and comfort for babies wearing diapers, since it reduces undesirable moisture and wetness in contact with their skin: this is a health and quality-of-life improvement and helps defend against promoting possible rashes or fungal infections of the skin by keeping the skin dryer.

    In reality, the baby will be more comfortable, so they will likely be requiring a change less often, which will spare plastic from the landfills.

    I think the only real alternatives would be to either use no diapers at all... monitor babies closely and make sure the diaper is changed immediately if they wet themselves in the slightest, or use porous cloth diapers.

    Very misleading for people to conclude from this headline that diapers somehow pose a risk of "brain swelling" for babies! I found a New York Times article about the process the researchers used. It requires a sequence of steps that begins with a tissue sample. The scientists "infuse" the tissue with the chemical **building blocks** of the polymer (not the polymer), making sure they evenly permeate the sample. The polymer forms inside the tissue (destructively chopping it up in the process at the chemical level), and then they add water causing the polymer to swell. The polymer itself does not ever cross the cell barrier, and it can't. That is why they inject the chemical building blocks. This is not something that can happen by touching or ingesting the polymer itself.

But I have heard or read from history similar reassurances saying about other things (cocaine in Coca Cola, lead in gasoline, trans fats, smoking, PCBs, MTBE, mercury, etc.) which we have now reconsidered as human health risks. Fracking was supposedly harmless; now it turns out it can cause earthquakes and pollute the groundwater...

      At the end of the excellent 1980s video series "The World of Chemisty" (in the last or second to last episode) Nobel-prize winner Roald Hoffman talks in passing about the wonders and great value of a new plastic called BPA (bisphenol A).
      http://www.learner.org/resourc...

      We now know that BPA can affect developing human brains:
      http://www.mayoclinic.org/heal...
      "Some research has shown that BPA can seep into food or beverages from containers that are made with BPA. Exposure to BPA is a concern because of possible health effects of BPA on the brain, behavior and prostate gland of fetuses, infants and children. "

      See also:
      http://science.slashdot.org/st...
      "The number of chemicals known to be toxic to children's developing brains has doubled over the last seven years, researchers said. Dr. Philip Landrigan at Mount Sinai School of Medicine in New York and Dr. Philippe Grandjean from Harvard School of Public Health in Boston, authors of the review published Friday in The Lancet Neurology journal say the news is so troubling they are calling for a worldwide overhaul of the regulatory process in order to protect children's brains. 'We know from clinical information on poisoned adult patients that these chemicals can enter the brain through the blood brain barrier and cause neurological symptoms,' said Grandjean. 'When this happens in children or during pregnancy, those chemicals are extremely toxic, because we now know that the developing brain is a uniquely vulnerable organ. Also, the effects are permanent.'"

      Unless people actually look for these materials in human brains directly, it is hard to be 100% sure there is no way they could get into the brain somehow. Although even if they get there, to be fair, then "the dose makes the poison" and what is the effect relative to the benefits? While Roald Hoffman was not more cautious about BPA, nonetheless, modern chemistry has produced all sorts of modern wonders, and it is hard to imagine modern life without it (including safe food storage against insects and bacteria).

      Even (life saving) antibiotics are now seen as having a down side that suggests they be used more precisely and also in the context of pro-biotics and/or fermented bacteria-rich foods etc. For example:

      I don't have a problem with a general attitude of being cautious with chemicals. I do as well. In addition to your list, there are also countless examples of feared things that were ultimately and definitively found NOT to be dangerous at all. One must use *both* prudent caution and reasonable cynicism in evaluating risks.

      What one cannot do is read a headline which is talking about a procedure used to prepare a microscope slide in a lab and jump to the conclusion that there is a danger to wearing diapers containing some material that happens to be formed in the process. Water is also used in the procedure. Should I be afraid of touching water?

      CRITICAL TO UNDERSTAND: The scientist did not apply the polymer to cells. They intentionally created the polymer INSIDE the cells.

      Silica gel (you know, the stuff in every pair of shoes that comes in a packet labeled do not eat) has a common property to the polymer described here: it absorbs water. Should I be worried that holding silica gel will make my brain swell? I hope you don't think so, because I don't have the inclination to dispel all the chemical fallacies that would be involved in that fear.

      Did you read the article I linked to? Let me reiterate the key components of the process the scientists describe that are not compatible with a misleading and fear-mongering headline:
      1) This discovery has nothing to do with research on health risks. It was a process developed in a context of intending to find a way to expand tissue samples in a laboratory for microscopic examination.
      2) The scientists apply polymer PRECURSORS to tissue samples. The POLYMER is not applied. (Already, completely different chemicals being talked about.) I would say in prudence: don't apply the polymer precursors to a wet area of your body like your mouth. ;-)
      3) As the polymer forms it chops up the cell. In a living cell, it is now dead at this point, not "swollen."
      4) The precursors are applied directly to the cells they want to examine. The precursors beginning forming polymer, which is not membrane permeable and therefore would not be able to migrate from your groin to your brain.
      5) THEN water is added so the polymer will absorb it and expand uniformly in all directions and "stretch out" the structures for microscopic examination.

      I hope you see why even applying the polymer precursors to the moist environment of your groin would not cause your brain to swell. Perhaps you could be concerned it might increase your risk of dry skin and diaper rash! Oh the horror.
