Some new treatments are helping patients with spinal cord injuries. Now a small plastic device may be added to a variety of treatments.<br /><br />A tiny device built by scientists at MIT and the Singapore-MIT Alliance for Research and Technology might be used to improve therapy treatments for patients suffering from spinal cord injuries.<br /><br />In cell therapy, clinicians create <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3584308/"><span style="color: #990000;">induced pluripotent stem cells</span></a> by reprogramming some skin or blood cells taken from a patient. To treat a spinal cord injury, these pluripotent stem cells can become progenitor cells, which differentiate into spinal cord cells. These progenitors are then transplanted back into the patient.<br /><br />These new cells can regenerate part of the injured spinal cord. However, pluripotent stem cells that don’t fully change into progenitors can form tumors. These are the risky cells that need to be removed.<br /><br />This research team developed a microfluidic cell sorter that can remove about half of the cells that can potentially become tumors without causing any damage to the fully formed progenitor cells.<div><br /></div><div>Read more <a href="https://www.lifescience.net/news/5592/scientists-develop-a-low-cost-device-to-make-cell-/"><span style="color: #990000;">here</span></a>.</div><div><br /></div>Alice C.

<p class="MsoNormal">January 20, 2024<o:p></o:p></p>
<p class="MsoNormal">This essay is an extended and updated version of an article
I wrote for VirtueOnline in 2012, entitled "On the Bible and Science:
Preliminary Principles Associated with God's Revelatory Purposes."</p>
<p class="MsoNormal">It is a horrendously false idea that the Christian faith and
empirical science are enemies, that these fields can never come to agreement.
While God has directly inspired and authorized the scriptures according to His
divine purposes (Isaiah 55:8-11, 2 Timothy 3:14-17), we have to admit that He
is also on the side of science. He supports (and has actually established) the
real purpose of science among humans, that is, the search for truth. However,
we can be sure that God is not for that 'science' which is done without
integrity. He is not for research done for political purposes and which bends
both the methods of fact-finding and the interpretation of the results so that
that they support whatever the researcher wants to publicly promote. As an
individual who had my dissertation research published in a scientific journal,
I know how easy it is to falsify data. I could have easily done so and no one
would have known the difference.<o:p></o:p></p>
<p class="MsoNormal">Fortunately, both deliberate manipulation of data and
ignorant errors must eventually fall to the wayside, for all misinformation is
short term. The truth will show itself again and again, and ultimately it
cannot be covered up. This is why I believe that the evidence revealed from our
scientific study of nature and scriptural truth (special revelation more
directly from God) will eventually come together and be of one piece, a
wonderful tapestry without contradiction or interpretive conflict. But yes, we
still have a long way to go.<o:p></o:p></p><div class="left-news-content"><div class="news-content clearfix" style="float: left; margin-bottom: 20px;"><div class="hometext" style="float: left; line-height: 25px; width: 762px;"><div class="field field-name-body field-type-text-with-summary field-label-hidden" style="line-height: 25px;"><div class="field-items"><div class="field-item even"><br /></div><div class="field-item even">Read it all here: <a href="https://virtueonline.org/science-and-bible-relationship-revisited"><span style="color: #990000;">Science and the Bible: A Relationship Revisited | VirtueOnline </span></a></div><div class="field-item even"><br /></div></div></div></div></div></div>Alice C.

With FDA approval of zuranolone (Zurzuvae), women suffering postpartum depression can take an oral medication at home and experience <a href="https://www.yalemedicine.org/news/postpartum-depression-pill-zurzuvae-zuranolone#:~:text=The%20medication%2C%20zuranolone%20(brand%20name,be%20available%20in%20late%20fall.">improvement in as little as three days</a>. Zurzuvae is a medication belonging to the neuroactive steroid class. It acts on GABA receptors, providing rapid relief for postpartum depression.</div><div><br /></div><div>Zurzuvae may cause side effects such as dizziness, drowsiness, and nausea. It may also cause headaches or sleep disturbances.</div><div><br /><div><br /></div><div><b>Sickle Cell Disease</b></div><div><b><br /></b></div>On December 8, the U.S. Food and Drug Administration approved Casgevy, <a href="https://www.sciencenews.org/article/first-crispr-therapy-sickle-cell-fda">the world’s first CRISPR/Cas9 gene-editing therapy</a>. The treatment helps patients produce healthy hemoglobin. In people with the disease, hemoglobin is abnormal, causing red blood cells to become hard and crescent shaped, which can block blood flow.

This area of Sibumasu, a lower Palaeozoic marginal Gondwanan terrane, is shown to have been closely associated with Australia, North China (Sino-Korea) and other continental fragments from the supercontinent's northern equatorial sector, including South China at that time. Shared faunas also suggest a Kazakhstani and Laurentian association. Collections from eight sections yielded 10 newly discovered species and one new genus from ancient shoreface and inner shelf siliciclastic deposits. With the new taxa and revision of taxa known previously, we refine the age of the upper two formations of the Tarutao Group to the middle of Cambrian Stage 10, and lower–middle Tremadocian. Two biozones are erected for Sibumasu: the Eosaukia buravasi Zone, encompassing all Cambrian sections from Ko Tarutao, and the Asaphellus charoenmiti Zone, encompassing the Tremadocian fauna discussed herein. The new genus is Tarutaoia and new species are Tsinania sirindhornae, Pseudokoldinioidia maneekuti, Pagodia? uhleini, Asaphellus charoenmiti, Tarutaoia techawani, Jiia talowaois, Caznaia imsamuti, Anderssonella undulata, Lophosaukia nuchanongi and Corbinia perforata. Other taxa reported for the first time from Tarutao are Mansuyia? sp., Parakoldinioidia callosa Qian, Pseudagnostus sp., Homagnostus sp., Haniwa mucronata Shergold, Haniwa sosanensis? Kobayashi, Lichengia simplex Shergold, Pacootasaukia sp., Wuhuia? sp., Plethopeltella sp., Apatokephalus sp., Akoldinioidia sp. 1 and Koldinioidia sp.</div></div></div></div><div><br /></div><div><br /></div></div>Alice C.

Its discovery is believed to shed light on a point in evolutionary history when the very first fish ventured out onto land. It is sometimes referred to as a "<a href="https://en.wikipedia.org/wiki/Tiktaalik"><span style="color: #990000;">fishapod</span></a>".</p><p>Tiktaalik roseae is a genus of extinct lobe-finned fish from the late <a href="https://en.wikipedia.org/wiki/Devonian"><span style="color: #990000;">Devonian period</span></a>, when the earliest forests appeared along with land animals such as <a href="https://en.wikipedia.org/wiki/Arthropod"><span style="color: #990000;">arthropods</span></a> (<a href="https://en.wikipedia.org/wiki/Myriapod"><span style="color: #990000;">myriapods</span></a>, <a href="https://en.wikipedia.org/wiki/Arachnid"><span style="color: #990000;">arachnids</span></a> and <a href="https://en.wikipedia.org/wiki/Hexapoda"><span style="color: #990000;">hexapods</span></a>). Tiktaalik had some features like those of four-legged animals. It is an example of an ancient sarcopterygian fish which adapted to a swampy oxygen-poor water habitat. The creature is regarded by evolutionists as a transition from fish to tetrapod.</p>What I find exciting about this discovery is the critical method and logistics of the exploration over four summers in the Alaskan Arctic. Tiktaalik was discovered through a well-conceived methodically launched project to find a predicted specimen and demonstrates the predictive capacity of paleontology. <div><br /></div><div>The discovery by Daeschler, Shubin, and Jenkins was published in the April 6, 2006, issue of Nature and quickly recognized as a transitional form. <a href="https://en.wikipedia.org/wiki/Jennifer_A._Clack"><span style="color: #990000;">Jennifer A. Clack</span></a>, a Cambridge University expert on tetrapod evolution, said of Tiktaalik, "It's one of those things you can point to and say, 'I told you this would exist,' and there it is."<figure class="mw-default-size mw-halign-right" style="background-color: #f8f9fa; border-bottom-color: initial; border-bottom-style: initial; border-collapse: collapse; border-image: initial; border-left-color: rgb(200, 204, 209); border-left-style: solid; border-right-color: rgb(200, 204, 209); border-right-style: solid; border-top-color: rgb(200, 204, 209); border-top-style: solid; border-width: 1px 1px 0px; clear: right; color: #202122; display: table; float: right; font-family: sans-serif; font-size: 14px; line-height: 0; margin: 0.5em 0px 1.3em 1.4em; min-width: 100px; text-align: center;" typeof="mw:File/Thumb"><a class="mw-file-description" href="https://en.wikipedia.org/wiki/File:Neil_Shubin.jpg" style="background: none; border: 0px; color: #3366cc; display: block; overflow-wrap: break-word; position: relative; text-decoration-line: none;"><img class="mw-file-element" data-file-height="1764" data-file-width="2214" decoding="async" height="175" src="https://upload.wikimedia.org/wikipedia/commons/thumb/2/20/Neil_Shubin.jpg/220px-Neil_Shubin.jpg" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/2/20/Neil_Shubin.jpg/330px-Neil_Shubin.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/2/20/Neil_Shubin.jpg/440px-Neil_Shubin.jpg 2x" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 1px solid rgb(200, 204, 209); margin: 3px; vertical-align: middle;" width="220" /></a><figcaption style="border-bottom-color: rgb(200, 204, 209); border-bottom-style: solid; border-image: initial; border-left-color: rgb(200, 204, 209); border-left-style: solid; border-right-color: rgb(200, 204, 209); border-right-style: solid; border-top-color: initial; border-top-style: initial; border-width: 0px 1px 1px; caption-side: bottom; display: table-caption; font-size: 12.376px; line-height: 1.4em; padding: 0px 6px 6px; text-align: left; word-break: break-word;">Neil Shubin, one of the paleontologists who discovered <i>tiktaalik</i>, holding a cast of its skull.</figcaption></figure><div><br /></div>"After five years of digging on Ellesmere Island, in the far north of Nunavut, they hit pay dirt: a collection of several fish so beautifully preserved that their skeletons were still intact. As Shubin's team studied the species they saw to their excitement that it was exactly the missing intermediate they were looking for. 'We found something that really split the difference right down the middle," Daeschler said.<div><br /></div><div>Ahlberg and Clack’s review explains Tiktaalik's importance:<br /><br /><i>The Nunavut field project had the express aim of finding an intermediate between Panderichthys and tetrapods, by searching in sediments from the most probable environment (rivers) and time (early Late Devonian). Second, Tiktaalik adds enormously to our understanding of the fish-tetrapod transition because of its position on the tree and the combination of characters it displays.</i><br /><br /><div>Martin Brazeau, gloats:</div><div><br /></div><div><i>"Creationists haven't said a lot about Tiktaalik, and it's no surprise. However, a few responses have trickled out and they more or less run in the same vein. I thought this was <a href="http://www.uncommondescent.com/index.php/archives/1004">a rather telling remark</a> on Tiktaalik posted over on Dembski's blog. We're treated to an excerpt of the <a href="http://www.pandasthumb.org/archives/2006/04/post_10.html">pre-transformation version of the DI's original response</a> that goes:<br /><br />I especially like Crowther’s last sentence which I present in its original form (bold type included): “There’s a problem with the Darwinist position that runs even deeper than this, however: If Darwinian evolution is an undisputed fact, as its chief defenders routinely claim, why is this fossil find being billed as such an crucial piece of evidence?”<br /><br />Icing on the cake! I love it!!!<br /><br />What I love even more is all this rhetoric and absolutely no reference to the actual fossil material. So, I'll take that as meaning that these guys have nothing to say about its transitional status. The real icing on the cake is all this puff and no real substance.<br /><br />Unfortunately, the media's response to the discovery is not quite the same as the palaeontological community's interpretation of it. Therefore, by responding to these articles, creationists and their ilk are just blowing smoke. The importance of Tiktaalik has nothing to do with proving the fish-tetrapod transition. That's pretty much taken care of by a wealth of data from the past 100 years."<br /></i><br />One wonders why Brazeau even cares what creationists think. Does he harbor a certain fear that maybe the scheme he presents could point to a Creator?</div><div><br /></div><div><br /></div></div></div>Alice C.

In one approach, Genesis is treated as a literal and accurate description of human origins and early human history. In this literalist view, Adam and Eve were not only real people, but they were also the first people on Earth. In the other approach, Genesis is read as a series of folk stories and myths that reveal important truths about humanity when interpreted allegorically. In this view, Adam and Even are characters in the creation story rather than real people who existed in history. The important point in this mode of interpretation is not that Adam and Eve were real historical characters but that that the story reveals important truths about human pride, disobedience, estrangement from God, and the hope of reconciliation.<br /><br />In The First Lords of the Earth, Alice Linsley offers a fresh perspective through the lens of Biblical anthropology. Drawing from over forty years of research into Genesis along with scientific studies of ancient cultures, symbols, beliefs, and linguistic analysis, Linsley makes the case that the important figures of Genesis were not only real people but were members of the early Hebrew caste of ruler-priests who moved from Africa into the Fertile Crescent and Ancient Near East. As just one example, she makes the case that the Adam and Eve of Genesis were not the first humans, but neither were they mythical archetypes. Instead, Adam was a real ruler who lived in a vast area around the Nile River and whose sons Cain and Seth married the daughters of Enoch, who lived at the same time. The book’s exploration of early Hebrew kinship, marriage, and ascendancy patterns places these and later Biblical characters in an evidence-based historical context and provides rich anthropological context for the Scriptural accounts of the lives of later figures such as Abraham, Noah, and Joseph. The title of the book derives from the anthropological evidence that these and other early figures in Scripture were powerful ruler-priests with extensive domains in the lands described in the Bible.<br /><br />The book offers a detailed look at a number of factors of early Hebrew culture, but one of the most interesting was the evidence that belief in God Father and God Son, along with a Messianic hope, was an important theme in Hebrew thought going back 6000 years that foreshadowed the beliefs of Christianity. Linsley makes a powerful case that the foundations of Christianity were present in early Horite and Sethite Hebrew beliefs that were present long before Abraham’s time.<br /><br />The First Lords of the Earth is an excellent resource for a wide range of readers, including those interested in early Hebrew history for its own sake and for those who want to deepen their understanding of Scripture.<br /><br /><br />END<br /><br /><br />Related Reading: <a href="https://college-ethics.blogspot.com/2023/08/first-lords-and-their-authority.html"><span style="color: #990000;">The First Lords and Their Authority</span></a>; <a href="https://justgreatthought.blogspot.com/2023/07/the-first-lords-and-messianic.html"><span style="color: #990000;">The First Lords and Messianic Expectation</span></a>; <a href="https://jandyongenesis.blogspot.com/2022/11/the-adam-and-eve-of-history.html"><span style="color: #990000;">The Adam and Eve of History</span></a><br /><br /><br /></div>Alice C.

This gives the body a head start in the fight against disease in the event of a later exposure. Vaccines based on killed or weakened viruses have long been available, exemplified by the vaccines against polio, measles, and yellow fever. In 1951, Max Theiler was awarded the Nobel Prize in Physiology or Medicine for developing the yellow fever vaccine.</div><div><br /></div><div>Yellow fever was fairly common and claimed many lives in the tropics. The disease is caused by a virus and is transmitted to people by insects and also from one person to another. Max Theiler succeeded in transmitting the virus to mice, which paved the way for more in-depth research. When the virus was transmitted between mice, a weakened form of the virus was obtained that could make apes immune. In 1937 Theiler succeeded in obtaining an even weaker variant of the virus.

This is an opportunity to be at the forefront of something that could potentially shake up the job market in the years to come.<br /><br />If you are looking for encouragement and advice, here are some tips that should help anyone who teaches a STEM-related course.<div><br /><br />1. <b>Integrate All Four STEM Subjects</b><div><b><br /></b>As stated earlier, STEM combines four subjects: Science, Technology, Engineering, and Mathematics. As a STEM teacher, you should familiarize yourself with all these subjects and be ready to integrate them into your teaching methods. As a result, the students will get real-world, meaningful learning. </div><div><br />As a STEM educator, you help your students apply what they learn to real-life situations. You can do that by setting up practical lessons where their knowledge is tested, and they have to use what they have learned to solve real-life problems.<br /><br />This should help them develop thinking, investigative, reasoning, and creative skills that should come in handy in this modern and technology-oriented world.<div><br /><br />2. <b>Have a Good STEM Curriculum</b><br /><br />It can be relatively hard to find a STEM curriculum that has been set out by the relevant educational authorities, particularly because it doesn’t exist. However, several sites have put up agood and reliable STEM lesson guides.<br /><br />One of the most popular and highly recommended ones is <a href="http://teachers.egfi-k12.org/">eFGI for Teachers</a>. Here, you will find a variety of tools to boost your students’ math and science skills, as well as ideas on how to enliven the classroom with engineering projects.<br /><br />They have lesson plans, class activities, outreach programs, and also web resources, among a host of other things that could guide you to make your STEM lessons as interactive and educative as possible.<br /><br />Another site that offers good and reliable lesson guides is <a href="https://www.teachengineering.org/">TeachEngineering</a>. However, you must be cautious in the STEM teaching guides you use because not every guide that claims to be a STEM guide is actually a STEM guide.<br /><br />Here are a few things you can use to determine if the guide is suited for STEM lessons.<br /><br />A good STEM lesson is guided by the seven-step engineering design process in solving problems:</div><div><br />Focuses on real-world problems.<div><br />Provides for multiple right answers and reiterates the importance of failure as a part of learning.</div><div><br />Involves students in productive teamwork.</div><div><br /></div><div>Teaches students to access reliability of information.</div><div><br /></div><div>Helps students to develop critical thinking and ability to analyze data.</div><div><br />Applies rigorous math and science content.</div><div><br />Immerses students in hands-on inquiry and open-ended exploration.</div><div><br />Supports a teaching process that is mainly student-centered and inquiry-based.</div><div><br />Requires students to tap into their design skills and create a prototype of the solutions.<br /><br />Using this checklist, you can now know which online teaching curriculum is good enough for you to use and can include in your STEM teacher preparation.</div><div><br /></div><div><br />Read more here: <span style="color: #990000;"><a href="https://www.msn.com/en-us/money/careersandeducation/seven-stem-teacher-tips-if-you-re-suddenly-teaching-stem/ar-AA1gIxcd">Seven STEM Teacher Tips If You’re Suddenly Teaching STEM</a><a href="https://www.msn.com/en-us/money/careersandeducation/seven-stem-teacher-tips-if-you-re-suddenly-teaching-stem/ar-AA1gIxcd"> (msn.com)</a></span>; <a href="https://asa-cwis.blogspot.com/2016/12/resources-for-stem-teachers.html">Resources for STEM Teachers</a><div><br /></div></div></div></div></div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><br /></div><br />Alice C.

Options include Kindle, paperback, and hard cover, and all are priced to accommodate the book lover on a tight budget.<br /><br />This book identifies the social structure and religious beliefs of the early Hebrew ruler-priest caste (6000-4000 years ago), their dispersion out of Africa, their territorial expansion, trade routes, and influence on the populations of the Fertile Crescent and Ancient Near East. It includes diagrams showing the kinship pattern of the biblical Hebrew.<div><br /></div><div>It exposes a widely held misconception that the early Hebrew had a patriarchal social structure. For that to be true, descent, inheritance, residence, authority, and the right to rule would be vested exclusively with males. This book shows that none of these features of the Hebrew social structure suggest a strict patriarchy. </div><div><br /></div><div>The rulers listed in Genesis were Hebrew and the social structure of the Hebrew ruler-priest caste was unusual for that time in that it exhibited considerable gender balance. The binary feature of their social structure and its balance of male-female authority is addressed in great detail in my book. These are evident also in the male-female narrative couplets found in the Bible.</div><div><br />There are many examples: the distinct duties/responsibilities of the mother's house versus the father's house; male prophets-female prophets; male rulers-female rulers; inheritance by male heirs-inheritance by female heirs, patrilocal residence-matrilocal residence; Hebrew patronymics-Hebrew matronymics; and in the Hebrew double unilineal descent pattern, both the patrilineage and the matrilineage are recognized and honored, but in different ways. </div><div><br /></div><div>The blood symbolism of the Passover associated with Moses has a parallel in the blood symbolism of the scarlet cord associated with Rahab. The abusive behavior of drunken Noah toward his sons has a parallel in the abusive behavior of drunken Lot toward his daughters.<br /><br />There is binary balance in the New Testament narratives also. Jesus restored the widow of Nain's deceased son to his mother (Luke 7:11-17). Jesus restored Jairus' deceased daughter to her father (Mark 5:21-43). <br /><br />When Jesus was presented in the temple His identity as Messiah was attested by the priest Simeon and the prophetess Anna.<br /><br />To understand the gender distinctions and binary balance of the early Hebrew, we must dismiss the false narrative that their social structure was patriarchal.</div><div><br /></div><div>Readers say this book brings the figures of the Old Testament to life. <br /><br />The research took 40 years, but I was able to make a rather complex subject easy to understand. I hope you will buy the book and discover answers to some perennial questions, such as:<br /><br /><ul><li>Who were the Horite Hebrew and the Sethite Hebrew?</li><li>Where is the oldest known site of Horite Hebrew worship?</li><li>Why did so many Hebrew men have two wives?</li><li>What was the difference in status between wives and concubines?</li><li>What types of authority did the biblical Hebrew recognize?</li><li>What were some symbols of authority among the early Hebrew?</li><li>How did their acute observation of the patterns in Nature inform their reasoning?</li><li>If Judaism is NOT the Faith of the early Hebrew, what did they believe?</li><br /></ul>It is ancient history, anthropology, and biblical studies wrapped into one fascinating read.

She says that donkeys made a <a href="https://academic.oup.com/book/41702?login=false">huge difference in humanity's ability to transport goods over long distances</a> by land due to the animals' endurance and ability to carry heavy burdens.<br /><br />"While rivers such as the Euphrates and Tigris in Mesopotamia and the Nile in Egypt could be used for transport of heavy and/or bulk goods, donkeys meant a massive increase and intensification of contacts over land," she says.</div><div><br /></div><div>Recht says this coincided with the increasing use of bronze during in the third millennium BC.

It holds 99.8% of the solar system's mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.<br /><br />The surface of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius) hot, while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions. One would need to explode 100 billion tons of dynamite every second to match the energy produced by the sun, according to <a href="https://www.nasa.gov/audience/forstudents/5-8/features/F_Violent_Sun.html">NASA</a>.<br /><br />The sun is one of more than 100 billion <a href="https://www.space.com/25959-how-many-stars-are-in-the-milky-way.html">stars in the Milky Way</a>. It orbits some 25,000 light-years from the galactic core, completing a revolution once every 250 million years or so. The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium. An older generation of stars is called Population II, and an earlier generation of Population III may have existed, although no members of this generation are known yet.<div><br /></div><div>Read more <a href="https://www.space.com/58-the-sun-formation-facts-and-characteristics.html"><span style="color: #990000;">here</span></a>.</div><div><br /></div><div><br /></div>Alice C.

This is in contrast to other marine mammals, whose average body size tends to decrease as their numbers increase. Researchers report that sexual selection was a strong driving force for males to grow bigger and to strengthen muscles in their neck and jaw that help them fight for mates. Both male and female sea lions evaded food shortages by diversifying their diets and, in some cases, foraging further from the shore.<div><br /></div><div>To explore how California sea lion ecology has changed as their population has grown, the researchers analyzed museum specimens of adult male and female California sea lions collected in central and northern California between 1962 and 2008. To estimate changes in body size, they compared the overall size of more than 300 sea lion skulls collected over the years. They also measured other skull features, such as the size of muscle attachment points, which allowed them to assess changes in sea lion neck flexibility and biting force.<br /><br /><div>Read more <a href="https://www.sciencedaily.com/releases/2023/04/230427114539.htm">here</a>.</div><div><br /></div><div><br /></div></div>Alice C.

We don’t want to lose the respect of our colleagues or jeopardize our careers because we identify as Christian, especially when we desire to be public and vocal about sharing God’s majesty in our work with others.” Sadly even in the Church, Loryn shared that Christian women in science face the challenge of, “feeling ashamed or not feeling safe to discuss their research for fear of ridicule or judgment, and feeling alone.” There is still work to be done, but thankfully there isn’t a shortage of Christian women role-models in STEM for the next generation of women and girls to look up to and see themselves represented.<br /><p><br /></p><p>Read more here: <a href="https://biologos.org/post/10-christian-women-to-know-stem-edition"><span style="color: #990000;">10 Christian Women to Know: STEM Edition - Post - BioLogos</span></a>; <a href="https://asa-cwis.blogspot.com/2016/10/sister-mary-celine-fasenmyer.html"><span style="color: #990000;">Sister Mary Celine Fasenmyer</span></a>; <a href="https://www.agnesscott.edu/lriddle/women/gervase.htm"><span style="color: #990000;">Sister Mary Gervase</span></a>; <a href="https://asa-cwis.blogspot.com/search/label/Agnes%20Giberne"><span style="color: #990000;">Agnes Giberne: A Lover of Science</span></a>; <a href="https://network.asa3.org/blogpost/999882/169929/Christian-Women-in-Science-Technology-and-Engineering"><span style="color: #990000;">Christian Women in Science, Technology and Engineering</span></a></p><p><br /></p></div>Alice C.

She once headed the department of earth and atmospheric sciences at the Georgia Institute of Technology, until she gave up on the academy so that she could express herself independently. She once <a href="https://www.city-journal.org/global-warming"><span style="color: #990000;">told a journalist</span></a>, “Independence of mind and climatology have become incompatible.”<div><br /></div><div>She added, "Climatology has become a political party with totalitarian tendencies,” she charges. “If you don’t support the UN consensus on human-caused global warming, if you express the slightest skepticism, you are a ‘climate-change denier,’ a stooge of Donald Trump, a quasi-fascist who must be banned from the scientific community.”<br /><br />The climate models used by scientists working for the United Nations cannot explain why the climate suddenly cooled between 1950 and 1970, giving rise to widespread warnings about the onset of a new ice age.<br /><br />Curry notes that between 1910 and 1940, the planet warmed during a climatic episode that resembles our own, down to the degree. The warming cannot be blamed on CO2 emissions because the carbon-dioxide emissions from burning fossil fuels were relatively small in those years. Curry says, “almost half of the warming observed in the twentieth century came about in the first half of the century, before carbon-dioxide emissions became large.”<br /><br />Speaking of climate changes, she points to natural factors, of which there are many. These factors reveal far greater complexity than is generally acknowledged by global warming alarmists.<div><br /></div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjv8lpz5emT28kA4Fe53427AUe1Ooo7etHGPBfQEbiMVFc_hzFtn1UbKDXpdUhlVm48Bx6MLrqDPeCsnwgcg-X6xLO5iwA0LmPh2qyTBK_yd0Is8CRVjZrJV6TPPh7gY1nxMONfVYcVTvYwrBcFNrefyin3K0e9HbKyjcfJohzANh-mpMdxXfDIdMzm/s320/620px-Climate_influencing_factors.gif" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="217" data-original-width="320" height="264" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjv8lpz5emT28kA4Fe53427AUe1Ooo7etHGPBfQEbiMVFc_hzFtn1UbKDXpdUhlVm48Bx6MLrqDPeCsnwgcg-X6xLO5iwA0LmPh2qyTBK_yd0Is8CRVjZrJV6TPPh7gY1nxMONfVYcVTvYwrBcFNrefyin3K0e9HbKyjcfJohzANh-mpMdxXfDIdMzm/w380-h264/620px-Climate_influencing_factors.gif" width="380" /></a></div><div><br /></div><div><br /></div><div>The following organizations are in agreement that climate changes: the U.S. National Academy of Sciences, the National Academies of more than 30 other countries, the American Association for the advancement of science (AAAS), the American Meteorological Society (AMS), The American Institute of Physics (AIP), The Geological Society of America (GSA), The American Physical Society (APS), and the American Geophysical Union (AGU).<br /><br />However, among the scientists in these organizations there is a range of positions as to which factors contribute most to warming. All tend to agree that solar radiance and Earth-Sun geometry are very significant. Yet we hear about this less than we hear about the danger of CO2 emissions from fossil fuel energy sources.</div><br />Earth's climate varies from region to region and from age to age. Therefore, it is misleading to speak of "climate change". Instead, we should speak of "climate changes" over vast periods of time. The <a href="https://www.britannica.com/science/Pleistocene-Epoch"><span style="color: #990000;">Pleistocene</span></a> glacial epoch (2,600,000-11,700 years ago) saw substantial variations in the extent of glaciers and ice sheets. These variations were driven by changes in the distribution of solar radiation across Earth’s surface. The insolation pattern is strongly affected by the geometry of Earth’s orbit around the Sun and by the orientation, or tilt, of Earth’s axis relative to the direct rays of the Sun.<div><br /></div>Worldwide, the most recent glacial period, or ice age, culminated about 21,000 years ago in what is called the <a href="https://www.britannica.com/science/Last-Glacial-Maximum"><span style="color: #990000;">Last Glacial Maximum</span></a> (LGM). During this time, continental ice sheets extended well into the middle latitude regions of Europe and North America, reaching as far south as present-day London and New York City. Global annual mean temperature appears to have been about 4–5 °C (7–9 °F) colder than in the mid-20th century.<div><br /></div><div>The <a href="http://jandyongenesis.blogspot.com/2016/07/when-sahara-was-wet.html"><span style="color: #990000;">Sahara was once wet</span></a>, and with on-going reforestation projects and changes in monsoons, it will likely be wet again.</div><div><br /></div><div>The Botswanan basin in southern Africa was once a sea, filled by water from the Angolan Highlands. Thousands of <a href="http://www.physorg.com/news171790409.html"><span style="color: #990000;">stoneage tools have been found there</span>.</a> </div><div><br /></div><div>At its peak, Mega Lake Chad covered more than 400,000 square kilometers (150,000 square miles), making it the largest lake on Earth today.</div><br />Researchers identified two distinct <a href="https://asa-cwis.blogspot.com/2017/11/forests-in-transantarctic-mountains.html"><span style="color: #990000;">environments at the South Pole</span></a> at the close of the Permian Period. There was a warm rainforest with tree-ferns, palm trees, and baobab trees at the lower elevations, and a cooler mountainous region dominated by beech trees and conifers.</div><div><br /></div>NASA bases climate change on a 136-year record. <a href="https://climate.nasa.gov/vital-signs/global-temperature/"><span style="color: #990000;">According to NASA,</span></a> 16 of the 17 warmest years in the 136-year record all have occurred since 2001, with the exception of 1998. What happened to make 1998 different? This marked the completion of Earth's axial precession, a cycle of about 25,800 years (Earth's Great Year). Obviously, we have no climate records going back that far.<br /><br />In the cycle of Earth’s Great Year, the line off the North Pole axis (extending toward Polaris) scribes a complete circle in the heavens about every 25,800 years. A complete cycle takes between 25,000 and 28,000 years, depending on the amount of Earth's wobble. One cycle is Earth’s Great Year. Climate and atmospheric changes appear to become more acute toward the end and beginning of a new year.<div><br /><div>Judith Curry is not alone in her consideration of natural causes. In June 2013, Dr. <a href="http://www.drroyspencer.com/2013/06/still-epic-fail-73-climate-models-vs-measurements-running-5-year-means/"><span style="color: #990000;">Roy W. Spencer</span> </a>wrote, "Hundreds of millions of dollars that have gone into the expensive climate modelling enterprise has all but destroyed governmental funding of research into natural sources of climate change. For years the modelers have maintained that there is no such thing as natural climate change…yet they now, ironically, have to invoke natural climate forces to explain why surface warming has essentially stopped in the last 15 years!"</div><div><br /></div><div><div><br /></div>Related reading: <a href="https://asa-cwis.blogspot.com/2018/02/climate-science-learn-to-read-charts.html"><span style="color: #990000;">Climate Science: Learn to Read the Charts</span></a>; <a href="https://jandyongenesis.blogspot.com/2011/03/climate-cycles-indicate-dynamic-earth.html"><span style="color: #990000;">Climate Cycles Indicate a Dynamic Earth</span></a>; <a href="https://www.city-journal.org/global-warming"><span style="color: #990000;">Climate Science's Myth-Buster</span></a></div></div><div><br /></div><div><br /></div>Alice C.

It is mixed with water to form mortar or mixed with sand, gravel, and water to make concrete. Concrete is a mixture of broken stone or gravel, sand, and cement. In ancient times concrete often contained crushed seas shells.<br /><br />Cement-matrix composites include concrete (containing coarse and fine aggregates), mortar (containing fine aggregate, but no coarse aggregate), and cement paste (containing no aggregate, whether coarse or fine).<br /><br />The ancient Romans built <a href="http://time.com/4846153/ancient-rome-concrete-cement-seawater/"><span style="color: #990000;">extremely durable sea walls</span></a> using a concrete made from lime and volcanic ash to bind with rocks. Rather than eroding in the presence of sea water, the material gained strength from the exposure.

The bacteria, either Bacillus pseudofirmus or Sporosarcina pasteurii, are found in highly alkaline lakes near volcanoes, and are able to survive for up to 200 years without oxygen or food.
