  2. Organic #molecules delivered from #extraterrestrial materials may have played a key role in supplying building blocks for #life on #Earth.

    Now scientists report all five canonical #nucleobases—purines (#adenine and #guanine) and pyrimidines (#cytosine, #thymine and #uracil)—in samples returned from the C-type #asteroid (162173) #Ryugu.

    Samples from Ryugu, #Bennu and #Orgueil, which have a similar mineralogy and elemental composition, show purine-to-pyrimidine ratios negatively correlating with #ammonia.

    These observations indicate that the nucleobases in these samples may have formed via a shared pathway depending on the physicochemical environment of the respective parent bodies.

    The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the #prebiotic chemical inventory of early Earth.

  4. IIAR: IIAR Releases Tool to Compare Refrigerants. “The International Institute of Ammonia Refrigeration said it has released a “Refrigerant Evaluator Tool” to help IIAR members and others assess their refrigerant choices and evaluate their options as the Environmental Protection Agency phases out high global warming potential refrigerants.”

  5. 1st bloom has emerged 🙌

    #Anthurium #andraeanum ( #AKA #FlamingoFlower or #LaceLeaf or #PaintersPalette ). The #flowers are called #inflorescences & have two parts: the #spathe & the #spadix . This type of inflorescence is a #hallmark of the #plant family #Araceae that Anthurium adraeanum belongs to.

    In #NASA ’s #CleanAir #Study - A. andraeanum was #scientifically #proven to #remove #toxins like #formaldehyde & #ammonia from the air 🥰
