If a living thing is like the rain, what are the raindrops it is made of?</p> <p>This question has led thinkers over the centuries to posit the existence of exotic-sounding concepts. Entelechy, monads, infusoria. If you are writing a fantasy novel and need words to describe its magical elements, taking a look at the hypotheses on the substance of life will prove inspiring.</p> Sat, 12 Mar 2022 09:00:00 +0000 Jonathan Jarry M.Sc. 9049 at /oss /oss/article/technology/under-microscope-graphite <p>Pencils do not contain any lead, and they never did! The mistake in terminology can be traced back to the ancient Romans who drew lines on papyrus using pieces of actual lead, all the while not realizing it was incredibly toxic. Considering its toxicity, it’s really good that pencils never did contain lead. Could you imagine how much a child could ingest while chewing on their pencil?<br /></p> Mon, 08 Apr 2019 16:15:44 +0000 Ada McVean B.Sc. 7700 at /oss /oss/article/health/under-microscope-blood <p><img height="2693" width="2694" style="width: 600px; height: 600px;" class="file-original " src="/oss/files/oss/img_1617.jpg" alt="" /></p> Mon, 25 Mar 2019 19:31:36 +0000 Ada McVean B.Sc. 7665 at /oss /oss/article/general-science/under-microscope-leopard-gecko-skin <p><img height="2048" width="2048" style="width: 600px; height: 600px;" class="file-original " src="/oss/files/oss/53881502_2151870248185752_8549331448652365824_o.jpg" alt="" /></p> <p>Leopard geckos (Eublepharis macularius) are a popular pet in many countries. They’re fairly easy to take care of, small, rarely bite, (and when they do it’s pretty painless) and can live up to 25 years! </p> Wed, 20 Mar 2019 14:34:45 +0000 Ada McVean B.Sc. 7656 at /oss /oss/article/environment/under-microscope-pollen <p>Grains of pollen actually produce the male gametes (sperm cells) of flowering plants. They become dehydrated to better allow themselves to be carried on by wind, water and animals to other plants where they land in the gynoecium, the innermost part of a flower that contains the ovaries. After rehydrating itself, a pollen grain forms a pollen tube, through which it transfers sperm cells into the ovaries of the flower, completing the pollination process.</p> Mon, 11 Mar 2019 15:17:19 +0000 Ada McVean B.Sc. 7642 at /oss /oss/article/environment/under-microscope-bees-knees <p><img height="1536" width="2048" style="width: 600px; height: 450px;" class="file-original " src="/oss/files/oss/img00008.jpg" alt="" /></p> <p><img height="1536" width="2048" style="width: 600px; height: 450px;" class="file-original " src="/oss/files/oss/img00009.jpg" alt="" /></p> <p><img height="1536" width="2048" style="width: 600px; height: 450px;" class="file-original " src="/oss/files/oss/img00010.jpg" alt="" /></p> Wed, 06 Mar 2019 19:01:24 +0000 Adam Oliver Brown PhD and Ada McVean B.Sc. 7635 at /oss /oss/article/did-you-know-nutrition/under-microscope-sea-salt-vs-table-salt <p><img height="1536" width="2048" style="width: 600px; height: 450px;" class="file-original " src="/oss/files/oss/seasaltedited.jpg" alt="" /></p> <p> <img height="1536" width="2048" style="width: 600px; height: 450px;" class="file-original " src="/oss/files/oss/seasaltedited2.jpg" alt="" /></p> <p><img height="1536" width="2048" style="width: 600px; height: 450px;" class="file-original " src="/oss/files/oss/tablesaltedited.jpg" alt="" /> </p> Wed, 06 Mar 2019 18:54:24 +0000 Ada McVean B.Sc. 7634 at /oss /oss/article/did-you-know-environment/under-microscope-paramecium <p><img height="1536" width="1536" style="width: 600px; height: 600px;" class="file-original " src="/oss/files/oss/paramecium_1_edited.png" alt="" /></p> <p><img height="1536" width="1536" style="width: 600px; height: 600px;" class="file-original " src="/oss/files/oss/paramecium_2_edited.png" alt="" /></p> Wed, 06 Mar 2019 18:44:42 +0000 Ada McVean B.Sc. 7633 at /oss
