Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 1 Volcano Date Was 3,000% Wrong 火山日期为3000%错误 Volcanoes at the south end of California’s Salton Sea erupted as recently as the time of Christ, not 30,000 years ago, and may be active today. 3/18/2016 2 Volcano Date Was 3,000% Wrong 火山日期为3000%错误 Live Science reported the correction about Salton Buttes. It makes the five domes a possible threat for a new eruption. The buttes last erupted between 940 and 0 B.C., not 30,000 years ago, as previously thought, a new study detailed online Oct. 15 in the journal Geology reports. The new age — which makes these some of California’s youngest volcanoes — pushes the volcanic quintuplets into active status. The California Volcano Observatory, launched in February by the U.S. Geological Survey (USGS), already lists the area as a high threat for 3/18/2016 3 future blasts. Volcano Date Was 3,000% Wrong 火山日期为3000%错误 Last August, an earthquake swarm alerted the USGS of activity in the area. This was followed by a foul smell of rotten eggs over a wide area that could have come from an outgassing event in the volcanic field, not from a fish die-off as first suggested. This means the volcanoes are active today, not 30,000 years ago. A new helium-zircon dating technique was used to arrive at the new date. Scientists should have known, though, that the cones were young. If they had been underneath prehistoric Lake Cahuilla (a precursor to Salton Sea), they would have been covered with sediments. Native Americans worked the obsidian between 510 and 640 BC, the article said, but not before–probably because it wasn’t available before the recent eruptions. 3/18/2016 4 Volcano Date Was 3,000% Wrong 火山日期为3000%错误 What would happen if Salton Buttes erupted again? “The amounts of magma involved are relatively small and the impacts of an explosive eruption, meaning an ash cloud, would most likely be very local,” said UCLA geochronologist Axel Schmitt. His paper in Geology states, “The (U-Th)/He eruption age is younger and significantly more precise than previous ages for these volcanoes, and is the first indication that the eruption of obsidian flows coincided with human presence in the region.” 3/18/2016 5 Volcano Date Was 3,000% Wrong 火山日期为3000%错误 Long ages are a playground for speculation. It’s like giving a packrat vast numbers of closets for storing his junk. Rather than constrain scientific thinking, it produces irresponsible storytelling and puts the burden on others to explain why the tens of thousands of years, or millions, or billions, is unreasonable. When you see the catch-phrase “as previously thought,” always ask, “Who thought that?” If it wasn’t you, don’t let them lump you in with the storytellers. 3/18/2016 6 Gloria Deo 愿荣耀归上帝 3/18/2016 7 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 8 Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Biological solutions to physical challenges are inspiring new technologies. A fuel and its money are soon partners: A “scientific breakthrough” reported on PhysOrg is promising the possibility to store sunlight in chemical energy, the way plants do it with photosynthesis. “Nature inspires research to convert solar into liquid fuel” is the headline. 3/18/2016 9 Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Fish skin diodes: In a short piece in the category “Biomaterials,” Nature News explained why silvery fish have such bright skin, then turned the findings into an app. Three species of fish seem to have “found a way around a law of physics” that dictates that reflections from scales should be polarized. “The skin contains a mixture of two types of guanine crystal with different optical properties — when the two are present in a specific ratio, this mixture prevents polarization and maintains high reflectivity,” the article said, adding, “the principles at work in these fish could have applications in optical devices such as lightemitting diodes” (LED’s). 3/18/2016 10 Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Smart as a bird: Birds are exceptionally good at avoiding obstacles as they fly. Imagine building a robot that can do that. Cornell researchers are trying; they have a prototype flying robot that is claimed to be “smart as a bird,” according to PhysOrg. Although flying robots are common, the engineers were tackling “the hard part: how to keep the vehicle from slamming into walls and tree branches.” It’s scoring pretty good in the hits and misses game but having some trouble in wind. As they improve their bird mimicking, they might come up with a device with “tremendous 3/18/2016 11 value in search-and-rescue operations.” Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Wood you believe: “Using the legendary properties of heartwood from the black locust tree as their inspiration, scientists have discovered a way to improve the performance of softwoods widely used in construction.” Thus begins an article on PhysOrg titled, “Inspiration from Mother Nature leads to improved wood.” It’s not that wood is faulty for trees, but in construction, builders would like to prevent moisture absorption and warping. The article says, “wood’s position as a mainstay building material over the centuries results from a combination of desirable factors, including surprising strength for a material so light in weight.” Since the black locust waterproofs its sapwood with flavonoids, turning it into rot-resisting heartwood, “The scientists used this process as an inspiration for trying an improved softwood” like spruce to make it more stable. 3/18/2016 12 Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Protein origami: It would be nice to make selfassembling materials the way cells do with automatically-folding proteins. “Proteins are able to self-assemble into a wide range of highly ordered structures that feature a diverse array of properties,” another article on PhysOrg begins. “Through biomimicry — technological innovation inspired by nature – humans hope to emulate proteins and produce our own version of self-assembling molecules.” That’s why the U.S. Department of Energy is studying the “folding funnel,” an energy diagram that captures how a protein falls through a guided pathway into its target shape, 3/18/2016 13 achieving the goal with minimal free energy. Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Firefly lanterns: LED’s are quickly becoming established as the light bulbs of the future because of their high efficiency. Korean scientists publishing in the Proceedings of the National Academy of Sciences have created a “Biologically inspired LED lens from cuticular nanostructures of firefly lantern.” Why look at fireflies instead of engineering textbooks? Fireflies have “recently inspired many imaging and display applications,” they said, because their “Cuticular nanostructures found in insects effectively manage light for light polarization, structural color, or optical index matching within an ultrathin natural scale.” The fireflies’ “highly efficient” lanterns send “strong optical signals” desirable in human applications. The short abstract of this paper mentioned 3/18/2016 14 biological inspiration no fewer than six times. Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 Robots to reach out and touch: Word of the day: haptics. Haptics is the psychology of touch. Touch involves more than physical contact; it requires sensation and signaling. Can robots do that? PhysOrg reported that a Swedish design engineer is trying to outfit robots with “Simple Haptics,” a sense of touch. “Camille Moussette explores how interaction designers can leverage and embrace the sense of touch to develop interfaces and experiences that go beyond traditional visual and formbased aesthetics.” This implies that even your finger has designs that engineers wish to imitate. Moussette wants to “develop haptics from a design perspective… leading to a new field of activities labeled haptic interaction design.” The word design appears 17 times in the short article. 3/18/2016 15 Inventions Inspired by Mother Nature’s Designs 来自大自然的发明灵感设计 These examples show that scientists believe in intelligent design in spite of their evolutionary inclinations. They even go beyond the self-imposed constraints of the Intelligent Design Movement by identifying the designer by name: “Mother Nature.” 3/18/2016 16 Gloria Deo 愿荣耀归上帝 3/18/2016 17 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 18 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 Sampling bacteria inhabiting our belly buttons sounds like fun, but do the results tell an evolutionary story? Some science questions might arouse curiosity even if not practically useful. One of them is “belly button ecology.” PhysOrg posed the question alongside a cave-like navel: “Ever wonder what’s living in there?” Some scientists in Florida decided to engage citizens in a survey of their navels. Their sample is instructive of where the researchers were coming from: 3/18/2016 19 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 Over the past six months, we have sampled over five hundred volunteers for belly button bacteria. We focus on the first two subsamples (60 individuals in total): a sample from the Science Online meeting of science communicators (January 13–15, 2011, Raleigh, NC, USA), and a sample from the Darwin Day at the Museum of Natural Sciences in Raleigh, NC(February 12, 2011). [Materials and Methods, Hulcr J, Latimer AM, Henley JB, Rountree NR, Fierer N, et al. (2012) A Jungle in There: Bacteria in Belly Buttons are Highly Diverse, but Predictable. PLoS ONE 7(11): e47712. doi:10.1371/journal.pone.004771.] 3/18/2016 20 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 What did they find? Lots of bacteria. Archaea were rare, but each navel contained about 67 species on average. Certain species tended to be more common, forming related clusters called “oligarchs,” but no species was universally found in all individuals. 3/18/2016 21 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 A simple experiment like this shows that drawing conclusions is difficult. Even the simplest observations did not lead to confident conclusions: “Such oligarchs were represented by multiple reads in most sampled human individuals, yet not a single one of the oligarchs is present in all samples.” What does that mean? The researchers didn’t control for simple things like lifestyle habits (swimmers vs mud racers), hygiene, sex, age, and other factors, like using other mammals as outgroups. They just swabbed a few dozen human belly buttons and looked in petri dishes for what turned up. In addition, they defined a “phylotype” arbitrarily, choosing RNA differences of 3% as diagnostic of species. 3/18/2016 22 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 What if they had used 2%, or 4%, or 10%? In addition, they chose to ignore rare species, which might have something to say about the conclusions. It appears not much more can be said than, “Here are the bacteria that were found in certain individuals’ belly buttons from certain locations at a certain time.” How would they know whether science teachers and attendees at a Darwin Day event have different navel ecologies than normal people? 3/18/2016 23 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 The authors appeared eager to attach some evolutionary significance to their results. One of the team said, “The common, abundant species are from a relatively small number of evolutionary lines, indicating that they have evolved traits that make them at home on human skin.” That, however, is a statement of ideology, not a conclusion drawn from the data. It doesn’t really add anything new to evolutionary theory. Everyone, even creationists, already knows that similar organisms, like orchids, tend to inhabit similar environments. 3/18/2016 24 Evolutionists Indulge in Navel-Gazing 进化论者沉浸在注视脐 If we can’t understand evolution by studying data right under our chins, what can evolutionists possibly infer from observations harder to come by? It’s nice to ask unique questions, and worthwhile to involve “citizen scientists” in research, but this study only serves to reinforce a Law of Evolution and its converse: the more abundant the data, the less storytelling. 3/18/2016 25 Gloria Deo 愿荣耀归上帝 3/18/2016 26 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 27 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Researchers discovered bacteria at the ocean floor that conduct electrons at distances more than a centimeter through elaborate cables. Publishing in Nature, Danish researchers with American colleagues determined that the seafloor is full of “live wires” that may play an essential role in ocean ecology, if not the ecology of the whole biosphere. These wires are formed by colonies of “novel members of the deltaproteobacterial family Desulfobulbaceae” that effectively form electrical cables, complete with insulation. 3/18/2016 28 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 A few years ago, these researchers had detected electric currents in the ocean floor. How they were mediated, though, was unknown till now. In the Introduction to their paper, they explained why the current is necessary: Marine sediments become anoxic because oxygen is consumed by microbial processes at the surface. Without available oxygen the microorganisms living below the surface are supposed to depend on energetically less favourable, anaerobic processes. Recently, however, electric currents have been found to directly connect oxygen reduction at the surface with sulphide oxidation in the subsurface, even when oxygen and sulphide are separated by more than 1 cm. Half of the sediment oxygen consumption can be driven by electrons transported from below. 3/18/2016 29 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 The spatial separation of oxidation and reduction processes invokes steep pH gradients leading to distinct dissolutions and precipitations of minerals. Microbial activity apparently drives the electrochemical halfreactions and the establishment of electron-conducting structures through the sediment. 3/18/2016 30 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Science Daily reported on this discovery on Oct. 24, saying that a mystery of electrical conductivity in the seafloor has been solved by the discovery of these bacteria. “They make up a kind of live electric cable that no one had ever imagined existed,” the article said. It quoted one of the researchers’ reactions: “On the one hand, it is still very unreal and fantastic. On the other hand, it is also very tangible,” said Professor at Aarhus University, Lars Peter Nielsen. 3/18/2016 31 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Another interesting summary can be found (appropriately) on Wired.com. The article includes six illustrations and photographs of the “marvelous microbes.” Even though they are 1/100 the diameter of the human hair, they have an elaborate structure with 15 to 17 channels down their exteriors that match up from cell to cell, forming a continuous protective sheath, like insulation. Their smallness should not diminish what they accomplish:“Were bacteria the size of humans, the signals would be making a journey 12 miles long.” The fragile cables break easily, but because they are alive, they can grow and regenerate themselves, unlike man-made cables. 32 3/18/2016 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 A single teaspoon of mud from the seafloor contains at least a half mile of these living cables. Moreover, the researchers found these in sediments from widely distributed samples, suggesting that much of the planet conducts electricity from the anoxic layer to the oxic layer. The electrical charge circuit is completed by ions in seawater, producing water in the process. This has led the researchers to speculate on their role in planetary ecology. In their concluding discussion, they asked follow-up questions and paid a compliment to evolution for creating electrical engineers: 3/18/2016 33 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Bacterial micro-cables represent a hitherto unknown lifestyle, which immediately raises many intriguing questions for further research: How are energy conservation and growth allocated among the cells? What is their genetic and metabolic diversity? How are filament division and dispersal controlled? What is the molecular and electronic basis of the electron transport? How widespread are they in nature? Transmission improvement and control of electric currents have been major drivers for electronic innovation. It appears that biological evolution has worked successfully in the same direction. 3/18/2016 34 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Wired.com’s article said, “It’s possible that, at the microbial level, the deep seafloor is humming with current.” The final caption recognized the planetary implications of the living power grid: With so much electricity being transferred, are other organisms tapping the lines? Might the Desulfobulbaceae be a power source for entire asyet-unappreciated deep-sea microbial ecologies, which in turn shape some of the planet’s fundamental biogeochemical processes? That’s “an interesting possibility,” said Nielsen, but it’s still speculation. 3/18/2016 35 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Less speculatively, the Desulfobulbaceae are definitely breaking down iron sulfides and carbonates in deeper sediment, while generating iron oxide and magnesium calcite at the surface, Nielsen said. The latter are important compounds for life in the oceans above, and ultimately on land. If the new Desulfobulbaceae are as widespread and populous as they seem, they could be an important component of life’s deep-time cycles. 3/18/2016 36 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 In the Editor’s Summary at Nature.com, the editors added a biomimetic angle to the story: A major challenge for multicellular organisms is that of supplying every cell with food and oxygen. Nils RisgaardPetersen and colleagues report a surprising solution to the problem, arrived at by multicelluar filamentous Desulfobulbaceae bacteria several centimetres long, living in the upper layers of marine sediments sampled in Aarhus Bay, Denmark. These organisms seem to function as living electric cables, transporting electrons from sulphides generated in organic matter in deeper anoxic sediments to the oxygen available in the surface layers. These living microcables raise a host of topics for future research, and could also find technological applications. 3/18/2016 37 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 The original paper by researchers at Aarhus University in Denmark was published by Nature on Nov. 8, though posted online on Oct. 24. Finding bacteria that form insulated electrical cables that may play a fundamental role in the ecology of the planet goes to show how much remains to be discovered about the “primitive” microbes surrounding us. Source: Pffefer, Larson et al., “Filamentous bacteria transport electrons over centimetre distances,” Nature 491, 08 November 2012, pp. 218–221, doi:10.1038/nature11586. 3/18/2016 38 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 It will be interesting to see if similar electrical cabling occurs in other contexts, such as in the soil networks known to connect plants with each other. This intriguing discovery is another example of the empirical trend against evolution: the closer scientists look at the microbial world, the more complex and interconnected it is found to be, and the less plausible the evolutionary just-so stories become. These bacteria appear to exist not only for their own sakes, but also to enable nutrient cycles that affect the whole biosphere. How would the first organisms survive without them? How did they form such elaborate structures? 3/18/2016 39 “Very Unreal and Fantastic”: Electric Cables Created by Bacteria 创建由细菌“非常虚幻和意想不到的”电力电缆 Evolutionists can’t just wave their hands and say they “evolved to” conduct electricity more effectively by transmitting electrons through their interiors, and then “evolved to” add insulating sheaths for “transmission improvement.” No teleology allowed for Darwinists. Their critics can rejoice at here another fine example of sophisticated design, not only in the bacteria themselves, but also in their functional role for their ecology, and possibly the biogeochemical balance of the entire world. 3/18/2016 40 Gloria Deo 愿荣耀归上帝 3/18/2016 41 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 42 Jellyfish for Your Health 水母为了您的健康 Jellyfish have inspired a cancer cell search tool – just one of new products and services inspired by nature. Tentacle probe: “Inspired by marine creatures that present long tentacles containing multiple adhesive domains to effectively capture flowing food particulates,” medical researchers built a new probe for blood that catches more circulating tumor cells (CTCs) than possible before, a new paper in PNAS reported. The tentacles allow a 3-D network arrangement of DNA strands that match rare cancer cells in small samples of blood. Science Daily describes what they did: 3/18/2016 43 Jellyfish for Your Health 水母为了您的健康 A new device from researchers at MIT and Brigham and Women’s Hospital overcomes those obstacles. Inspired by the tentacles of a jellyfish, the team coated a microfluidic channel with long strands of DNA that grab specific proteins found on the surfaces of leukemia cells as they flow by. Using this strategy, the researchers achieved flow rates 10 times higher than existing devices — fast enough to make the systems practical for clinical use. Science Daily posted a second article on this new bioinspired technology that can help “catch and release” marker cells before they metastasize, all by mimicking 3/18/2016 the tentacle method of jellyfish and sea cucumbers. 44 Jellyfish for Your Health 水母为了您的健康 Mr. Clean butterfly: Did you ever think about how hard it would be for a butterfly to fly with dirty wings? Fortunately, they come equipped with self-cleaning surfaces that resist water and dust. Researchers at Ohio State University have created a surface with similar properties that does a much better job at staying clean, Science Daily reported. We’ve heard about shark skin and lotus leaves with this property, but now butterflies – already a source of bio-inspiration for their bright colors – join the cleaning crew. Their research paper is entitled, “Bioinspired rice leaf and butterfly wing surface structures combining shark skin and lotus effects.” Put that texture inside pipes and you could “enhance fluid flow and prevent surfaces from getting dirty — characteristics that could be mimicked in high-tech surfaces for aircraft and watercraft, pipelines, and medical equipment.” 3/18/2016 45 Jellyfish for Your Health 水母为了您的健康 Automatic assembly: Proteins fold into intricate shapes by nature of their amino acid sequences. Scientists would like to build nanomachines that do that trick. In Nature last week (Nov 8), a team came a little closer to that goal by designing sequences that could fold into very simple shapes that constitute building blocks of higher protein structures, namely, alpha coils and beta sheets. So far the results only demonstrate proof of concept for the idea; natural proteins are much more complex. According to the Editor’s Summary of a Nature News & Views article on this effort, “The design principles and methodology described here should allow the design of a wide range of robust and stable protein building blocks for the next generation of engineered functional proteins.” Birte Hocker wrote, “With lengths of 80–100 amino acids, the authors’ protein structures are comparable in size to small protein domains that act as building blocks of larger, more complex proteins. The design of custom protein scaffolds that perform new functions is now conceivable, as is the assembly of 46 3/18/2016 bigger designed domains and quaternary complexes.” Jellyfish for Your Health 水母为了您的健康 Nano-machines: Speaking of proteins, many of them fold into molecular machines that capture random thermal energy and turn it into useful work. Scientists in Berlin succeeded in making a very simple lever-like device that turns randomly moving hydrogen molecules into specified work, New Scientist said. “Jose Ignacio Pascual at the Free University of Berlin in Germany and colleagues took inspiration from the natural world, where random motion powers structures such as proteins that move cargo around inside cells.” 3/18/2016 47 Jellyfish for Your Health 水母为了您的健康 Weird brain: In a case of biomimetics in reverse, one organism appears to mimic human intellectual abilities. That organism is Physarum polycephalum, a slime mold. Nature News published an article about how this colonial microbe shows an uncanny ability to “solve mazes, mimic the layout of man-made transportation networks and choose the healthiest food from a diverse menu—and all this without a brain or nervous system.” This organism is raising questions about what constitutes intelligence. The article includes a video clip of the organism solving a maze and creating a memory of the most direct path. 3/18/2016 48 Jellyfish for Your Health 水母为了您的健康 Our Creator must laugh when proud man struggles to catch up with the technologies He built into the simplest living things. Christian parents should think seriously about a biomimetics career for their science-precocious kids. It’s 100% Darwin-free and can help mankind. Start them on a science project to take a bug, spider or leaf from around the house and try to build something that imitates some desirable feature of its life. If they hesitate, tell them they can be Spiderman. 3/18/2016 49 Gloria Deo 愿荣耀归上帝 3/18/2016 50 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 51 Even for Quantum Particles, Time Flows One Way 即使是量子粒子,时间流动单程 Claims of time symmetry at the quantum level have been discounted by a high-reliability experiment by the Department of Energy. A press release from the SLAC National Accelerator Laboratory announced: Time marches relentlessly forward for you and me; watch a movie in reverse, and you’ll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time 3/18/2016 52 reversal symmetry. Even for Quantum Particles, Time Flows One Way 即使是量子粒子,时间流动单程 Now the BaBar experiment at the Department of Energy’s (DOE) SLAC National Accelerator Laboratory has made the first direct observation of a long-theorized exception to this rule. Digging through nearly 10 years of data from billions of particle collisions, researchers found that certain particle types change into one another much more often in one way than they do in the other, a violation of time reversal symmetry and confirmation that some subatomic processes have a preferred direction of time. 3/18/2016 53 Even for Quantum Particles, Time Flows One Way 即使是量子粒子,时间流动单程 Reported this week in the journal Physical Review Letters, the results are impressively robust, with a 1 in 10 tredecillion (1043) or 14-sigma level of certainty – far more than needed to declare a discovery. 3/18/2016 54 Even for Quantum Particles, Time Flows One Way 即使是量子粒子,时间流动单程 The BaBar experiment was an ideal test of the CPT (charge-parity-time) Theorem that states, “the three symmetries must remain in balance for any given particle system. If one of the symmetries is out of whack, at least one of the others must be, too.” Since 10 years of BaBar data already had evidence of CP asymmetry in hand, physicists thought it “was a good place to look for violation of time reversal symmetry that would serve to balance CPT as a whole.” Other hints of time reversal were harder to test. This one shows that the rate of time reversal for quantum events is outmatched: “the changes are happening at a different rate as time moves forward than when it is reversed,” a diagram caption states. 3/18/2016 55 Even for Quantum Particles, Time Flows One Way 即使是量子粒子,时间流动单程 One researcher said, “It was exciting to design an experimental analysis that enabled us to observe, directly and unambiguously, the asymmetrical nature of time.” BaBar also had another goal: “BaBar, which collected data at SLAC from 1999 to 2008, was designed to tease out subtle differences in the behavior of matter and antimatter that might help account for the preponderance of matter in the universe.” The “antimatter problem” still is a puzzle for modern cosmology. See also Science Daily’s coverage. 3/18/2016 56 Even for Quantum Particles, Time Flows One Way 即使是量子粒子,时间流动单程 It appears that time asymmetry, a consequence of the Second Law of Thermodynamics, is more firmly established by this experiment (confirmation to a one part in a tredecillion is pretty rare!), but we will leave it to the specialists to explain the implications. What impact will this have on cosmology? 3/18/2016 57 Gloria Deo 愿荣耀归上帝 3/18/2016 58 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

What makes it snap shut in a tenth of a second? Can we imitate its motion without muscles, wires or batteries? A press release from the American Physical Society’s Division of Fluid Dynamics sets up the questions: 3/18/2016 60 Venus Flytrap Still Mystifies, Inspires 维纳斯捕蝇草依然迷惑与启示 Plants lack muscles, yet in only a tenth of a second, the meat-eating Venus fly trap hydrodynamically snaps its leaves shut to trap an insect meal. This astonishingly rapid display of botanical movement has long fascinated biologists. Commercially, understanding the mechanism of the Venus fly trap’s leaf snapping may one day help improve products such as release-oncommand coatings and adhesives, electronic circuits, optical lenses, and drug 3/18/2016 61 delivery. Venus Flytrap Still Mystifies, Inspires 维纳斯捕蝇草依然迷惑与启示 Both Science Daily and Live Science reported on research by a French team that seeks to understand how botanical tissues can respond so quickly. One theory has been ruled out – that water travels from the inside cells to outside cells. By measuring the fluid pressure of the cells (a tricky experiment), Mathieu Colombani’s team found that movement of water is too slow to account for the traps’ fast action. They were scheduled to present their findings at an APU meeting in San Diego on 3/18/2016 62 Nov. 18. Venus Flytrap Still Mystifies, Inspires 维纳斯捕蝇草依然迷惑与启示 Live Science quoted Charles Darwin calling the Venus flytrap “one of the most wonderful plants in the world.” It grows in coastal bogs in North Carolina where soil nutrients are scarce – thus insects provide some of its nitrogen. Still, “despite the plant’s notoriety, its closing mechanism remains a mystery 250 years after its discovery.” Colombani’s team is the first to examine the mechanism at the cellular level. “The researchers are currently testing another popular explanation that says the elasticity of the plant’s cell walls changes, causing the leaves to destabilize and snap together,” Live Science said. “Colombani says that whatever the mechanisms behind the remarkable plant’s bite are, they could have potential applications in medicine or other 3/18/2016 63 fields.” Venus Flytrap Still Mystifies, Inspires 维纳斯捕蝇草依然迷惑与启示 Teachable Moment: Parents, kids are fascinated by the Venus flytrap. You can often buy the little plants in local nurseries. Build a little Venus flytrap terrarium at home for the family, and teach the kids how to feed and care for the plants like they would a pet. Much as they want to snap the traps over and over, they will quickly learn that the delicate plants need care and gentle handling. Tell them that here is something easily observed and tested right under a scientist’s nose, yet science cannot explain it after 250 years of trying. 3/18/2016 64 Venus Flytrap Still Mystifies, Inspires 维纳斯捕蝇草依然迷惑与启示 Focus on the beautiful design of these traps, how elegant and effective they are. Add that an explanation might lead to cool toys and products that operate without batteries. Kids need to know that there are still fascinating questions in science they might be able to solve, and that solving this puzzle might make the world a better place. Show them, though, that science needs to explain via experimental proof, not speculation. As it was for Faraday, Joule and other great creationary scientists who started young when they became intrigued by the wonders of nature, science is for 3/18/2016 65 everyone.

We’d sleep better and be better able to face our problems.” The article goes on to explain that gratitude implies another virtue: humility. Psychologists quoted in the article also said that materialism (the shopping-mall kind) has a negative relationship with gratitude. Robert Emmons, a UC Davis psychologist, 3/18/2016 69 is worried about the decrease in gratitude in society: Gratitude Is Good for Health 感恩是对健康有益 But despite the benefits, Emmons says, gratitude is in trouble. “Outside of happiness, gratitude’s benefits are rarely discussed these days. Indeed, in contemporary American society, we’ve come to overlook, dismiss or even disparage the significance of gratitude as a virtue,” he says. “We have become entitled, resentful, ungrateful and forgetful.” 3/18/2016 70 Gratitude Is Good for Health 感恩是对健康有益 Gratitude is difficult to cultivate, but needs to be, the article explained, describing ways to cultivate it, such as journaling. It’s so important that one filmmaker quoted in the article said it could “save the planet.” Usually, Thanksgiving is considered a time to be thankful to God for His provision. This article, though, seemed to distance itself from God in favor of “science,” making psychologists the new preachers – 3/18/2016 71 Gratitude Is Good for Health 感恩是对健康有益 Long embraced by religion as a “manifestation of virtue,” it’s one of the few things that “can measurably change people’s lives,” says Robert Emmons, a University of California-Davis professor who has been studying it since 1998 and is the author of the book “Thanks! How the New Science of Gratitude Can Make You Happier.” 3/18/2016 72 Gratitude Is Good for Health 感恩是对健康有益 None of the psychologists explained how gratitude (or any other “virtue”) evolved. For that matter, they didn’t explain how or why the human products of evolution could or should be grateful except perhaps in a utilitarian sense. 3/18/2016 73 Gratitude Is Good for Health 感恩是对健康有益 The article was also unclear about whom to thank. Gratitude requires an object—someone to whom to address thanks. Instead of illustrating the point with pilgrims or modern Bible believers thanking God, the psychologists featured a yoga practitioner who improved her health with gratitude exercises, and a non-traditional nun who said, “Gratitude gives an opening to the universe to give more good things. Gratitude is opening to receive more good things from the universe.” But can one really thank the universe? And is acting grateful for the purpose of getting more goodies really being grateful? Other than that, the article suggested learning to be in awe of nature, and “saying thanks” as a habit, without mentioning the object of the thanks. 3/18/2016 74 Gratitude Is Good for Health 感恩是对健康有益 Psychologists have it so wrong. If you’re trying to cultivate gratitude to get something out of it (like good mental health or a feeling of wellbeing), you’re not being grateful. And if you’re trying to be humble to be thought well of, you’re not really humble. You can’t just make grateful motions and vocalize humble words. These things require deep introspection about one’s motives. No faking; no duplicity allowed. Even when you think you’ve finally achieved humility or gratitude, you prove you haven’t. 3/18/2016 75 Gratitude Is Good for Health 感恩是对健康有益 Gratitude also requires an object, otherwise it’s just a selfish feeling. We can be grateful to people, such as parents, teachers and others who have been kind to us, but ultimately all gratitude needs to point to our Creator. One cannot thank the universe. One certainly cannot thank a cold, pointless process of natural selection. True gratitude is a form of praise – an act of worship. An old hymn got it right: 3/18/2016 76 Gratitude Is Good for Health 感恩是对健康有益 For the beauty of the earth, For the glory of the skies, For the love which from our birth Over and around us lies. Lord of all, to Thee we raise, This our hymn of grateful praise. 3/18/2016 77 Gloria Deo 愿荣耀归上帝 3/18/2016 78 Sermons From Science -- Dec 2012 科学布道-- 2012年12月 Sermons from Science is now published in both YouTube under the name “Pastor Chui” and also in PowerPoint slides in the website http://ChristCenterGospel.org.

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 79 Proteins Conduct Electricity 蛋白质的导电性 A remarkable finding at the single-molecule level shows a protein can conduct a large amount of electricity. A press release from the University of Cardiff describes how researchers isolated a single protein molecule and measured the passage of a current when placed between electrodes. This could represent a fundamental property of proteins that might explain their function. Two collaborators at the university said, “The highly conducting nature of this protein was a surprise and the result raises questions about the fundamental nature of electron transfer in proteins.” Could it be that 3/18/2016 80 proteins operate as transistors? Proteins Conduct Electricity 蛋白质的导电性 The team showed that the protein could carry large currents, equivalent to a human hair carrying one amp. The team also discovered that current flow could be regulated in much the same way as transistors, the tiny devices driving computers and smartphones, work but on a smaller scale: the proteins are only a quarter of the size of current silicon based transistors. The finding represents a leap forward in measurement at the nano scale. “Prior to this work, measurement of millions, if not billions of proteins was only possible, so losing crucial details of how an individual molecule functions.” The team used scanning tunneling microscopy (STM) to read the electronics of a single molecule of cytochrome b562, a protein just 5 nanometers (billions of a 3/18/2016 81 meter) long. Proteins Conduct Electricity 蛋白质的导电性 While the focus of the press release was on human engineering of this conductance for nanotechnology, the discovery may elucidate how the cell’s protein machines work. PhysOrg’s headline was, “Electronics of nature’s nano machines.” Its summary reads, “A team from the Cardiff University’s Schools of Biosciences and Physics and Astronomy have made a breakthrough in our understanding of proteins — the workhorse molecules of the cell and nature’s very own nano machines.” Details of the research have been published as a series of papers in the journals Nano Letters, ACS Nano, Small and Nanoscale, the press release 3/18/2016 82 indicated. Proteins Conduct Electricity 蛋白质的导电性 While it’s premature to compare proteins to human electrical tools, it is known that electron or proton transfer is essential to some of them, such as photosynthesis, ATPsynthase and other machines in the respiratory chain. What about the motor proteins dynein, kinesin, and myosin? What about the flagellar motor, mitochondrial machines and DNA transcription and translation machines? How is ATP energy transduced into proteins’ mechanical actions? This is a discovery to watch. If your own cells can be someday described as electronic machines, wouldn’t that be 3/18/2016 83 cool?

Pastor Chui http://ChristCenterGospel.org ckchui1@yahoo.com 3/18/2016 85 Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Adult stem cells continue to show promise as more about these pluripotent cells comes to light. Heart repair: Medical Xpress reported that organ-derived stem cell injections appear to have promise for tissue repair from myocardial infarction. The cells come from skeletal muscle or adipose tissue. A week after injection in subjects, “led to a substantial decrease in infarct size and a significant improvement in left ventricle function when compared with 3/18/2016 86 injections of cell culture medium alone.” Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Automatic wound repair: New Scientist reported that human skin appears to maintain a pool of adult stem cells used in repairing wounds. The cells exist in eccrine glands, “a type of sweat gland not found in animals,” the article said, adding, “Humans have three times more eccrine glands than hair follicles, making them the major contributor to new skin cells.” A researcher from Howard Hughes Medical Institute remarked that the finding was “unexpected and against current 3/18/2016 87 dogma.” Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Personalized medicine: According to Medical Xpress, researchers at Johns Hopkins and Memorial Sloan-Kettering are investigating the use of induced pluripotent stem cells for personalized medicine for those with genetic diseases. “This approach could move much of the trial-and-error process of beginning a new treatment from the patient to the petri dish, and help people to get better faster.” 3/18/2016 88 Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Rebuilding skeletal muscle: Another article on Medical Xpress discussed the potential for rebuilding muscle for those with degenerative diseases: “The therapy brings together two existing techniques for muscle repair – cell transplantation and tissue engineering – specifically, mesoangioblast stem cells delivered via a hydrogel cell-carrier matrix.” 3/18/2016 89 Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Stem cell transposable elements as un-junk: PhysOrg reported that linc-RNAs, a type of non-coding RNA thought to be genetic junk from viral invasions, appear to be landing spots for endogenous retroviruses (ERVs). David Kelley said that during his PhD work, “these repetitive hopping genes were a major nuisance, which got me thinking about what they were doing in the genome.” He and John Rinn found that they appear to promote gene transcription. “Perhaps more intriguingly, lincRNAs containing an ERV family known as HERVH correlated with expression in stem cells relative to dozens of other tested tissues and cells.” Rinn got emotional about this: “This strongly suggests that ERV transposition in the genome may have given rise to stem cell-specific lincRNAs. The observation that HERVHs landed at the start of dozens of lincRNAs was almost chilling; that this appears to impart a stem cell-specific expression pattern was simply stunning!” From there the article went on to 3/18/2016 90 speculate about how this evolved. Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 New kind of stem cell that may make regenerative medicine possible was reported by Medical Xpress. Adult epithelial cells can be coaxed into induced pluripotent stem cells with desirable attributes; “These seem to be exactly the kind of cells that we need to make regenerative medicine a reality.” For example, these cells could be used to create personalized medicine for cancer patients. The cells appear to take on the characteristics of the organ they are transplanted into. 3/18/2016 91 Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Fountain of youth: A way to refresh aging stem cells to look young again was found by researchers at the University of Toronto, Science Daily said. It involves inserting growth factors into the stem cells that turn aging factors off. “The discovery, which transforms aged stem cells into cells that function like much younger ones, may one day enable scientists to grow cardiac patches for damaged or diseased hearts from a patient’s own stem cells — no matter what age the patient — while avoiding the threat of rejection.” 3/18/2016 92 Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 With so much success continuing for adult stem cells, it seems superfluous to work with ethically-charged embryonic stem cells. Work continues on them as well, though – some of it raising fears of abuse. Nature News, for instance, reported that “Researchers have coaxed cultured embryonic stem cells to develop into eggs that then give rise to normal offspring” in mice. The article admitted ethical concerns. The experiments might lead to treatments for infertility; “However, the prospect of transplanting such oocytes into women raises major safety and ethical concerns that will need to be discussed carefully if the findings are repeated in humans.” But who will discuss the concerns? Who will decide what “carefully” enough means? And will it stop mad scientists more concerned 3/18/2016 93 about money than ethics? Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 The Family Research Council, which maintains StemCellResearchFacts.org website, recently congratulated Dr. David Prentice, “one of the world’s leading experts on adult stem cells,” for getting a scholarly article published in Tissue and Cell Engineering, titled, Remembering Pioneers in Patient Treatments. The article “talks about the groundbreaking new science that won Dr. Shinya Yamanaka this year’s Nobel Prize,” according to the FRC newsletter. 3/18/2016 94 Adult Stem Cell Breakthroughs Continue 成人干细胞的继续突破 Adult stem cells: proven track record, no ethical qualms. Embryonic stem cells: no track record, large ethical qualms. Enough said? We cannot trust the scientists themselves to regulate safety and ethics. These are issues for the public to insist on. Beware when scientists perform “public engagement” to determine what people approve; read this case of rigged public engagement on Evolution News & Views. 3/18/2016 95 Gloria Deo 愿荣耀归上帝 3/18/2016 96
