    CW: Soaps! (Could be more interesting than you think!)

    OK, so lately I've come to realize that even ingredients like glycerin can come from palm oil and/or coconuts. With surfactants on almost any cleaning product being derived from palm oil and/or coconuts (List of possible coconut derivatives: bloomingskin.com/christys-blog / List of possible palm oil derivatives: obvs-skincare.com/blogs/organi ) and the associated issues with them (Coconuts: investigations.peta.org/monkey , foodispower.org/our-food-choic / Palm oil: wwf.org.uk/updates/8-things-kn ), I've started looking for alternatives to cleaning products and goodness, it's been very difficult, but I found a solution I think!
    Olive oil soap! Yes, that is right. It's a soap…made from…wait for it…
    …olive oil! (OK and some water and maybe some other stuff added, too.)
    Commonly known as castile soap, it is actually totally fine for use as body, hair and even as a laundry detergent to wash by hand or in a washing machine with some slight modification ( thespruce.com/how-to-make-your )!!! So then you have a minimalist cleaning product that does the job just like the others but with severely less impact on the environment (Basically always.) and could even do a BETTER job in some cases…I should've been supporting this since the beginning, it seems…Do note that some still contain coconut or palm oil derivatives, so check the ingredients still (Of course!). Most times they seem to be vegan (As in no parts of non-human animals or something they produce is used and no testing for the olive oil soaps is taking place.), but again, you should check yourself.
    And if someone is doubting the efficacy of olive oil soap for cleaning, here are some sources: damascussoap.ca/blogs/skin-hai
    olividasoap.com/4-proven-benef
    theaustralianoliveoilsoap.com.
    pureplacid.com/blogs/journal/w
    With people boycotting palm oil so much, it seems like the best solution (Even if boycotting palm oil weren't the case and it were totally fine, the staggering difference in ingredients makes this the better choice for environmental reasons.). #Vegan #Veganism #Palm #Oil #PalmOil #Soap #Soaps #Clean #Cleaning #Cleanliness #Coconut #Coconuts #CoconutOil #Ethics #Ethical #Buy #Purchase #Boycott #Laundry #Detergent #LaundryDetergent #DeepDive #Olive #OliveOil #Castile #Bar #SoapBar #BarOfSoap #Bars #SoapBars #BarsOfSoap #Ingredient #Ingredients #Surfactant #Surfactants #PigtailedMacaque #PigtailedMacaques #Pigtailed #Macaque #Macaques #Child #Labour #ChildLabour #Work #Job #RightsViolation #RightsViolations #Abuse #Violence:vegan:

    Deep Breaths Renew Lung Surfactants + A Special Announcement

    Taking a deep breath may actually help you breathe easier, according to a new study. When we inhale, air fills our alveoli–tiny balloon-like compartments within our lungs. To make alveoli easier to open, they’re coated in a surfactant chemical produced by our lungs. Just as soap’s surfactant molecules squeezing between water molecules lowers the interface’s surface tension, our lung surfactants gather at the interface and lower the surface tension, making alveoli easier to inflate.

    But things are a little more complicated in our lungs than in our kitchen sink because of our constant cycle of breathing, which stretches and compresses our lungs’ surfaces and surfactant layers. Imagine a flat interface, lined with surfactant molecules; then stretch it. As the interface stretches, gaps open between the surfactant molecules and allowing molecules from the interior of the liquid to push their way to the newly stretched interface, changing the surface tension. If the interface gets compressed, some of the excess molecules will get pushed back into the liquid bulk.

    In looking at how lung surfactants respond to these cycles of compression and stretching, the researchers found that the lung liquid develops a microstructure during cycles of shallow breathing that makes the surface tension higher, thus making lungs harder to fill. In contrast, a deep breath like a sigh replenished the saturated lipids at the interface, lowering surface tension and making lungs more compliant. So a deep sigh actually can help you breathe easier. (Image credit: F. Møller; research credit: M.. Novaes-Silva et al.; via Gizmodo)

    P.S. — I’ve got a book (chapter)! Several years ago, I joined an amazing group of women to write two books (one for middle grades and one for older audiences) about our journeys as scientists. And they are out now! In fact, today we’re holding a “Book Bomb” where we aim for as many of us as possible to buy the book(s) on the same day. If you’d like to join (and get ahead on your gift shopping), here are (affiliate) links:
