「我們一生的年日是七十歲,若是強壯可到八十,但其中所矜誇的,不過是勞苦愁煩,轉眼成空,我們便如飛而去。」(詩篇九十:十)	
	有了創造主,關於人生的問題不再向『人』尋問,而是改向『上帝』!首先,人在上帝眼中處於什麼位置呢?根據《聖經—創世記》,上帝用了五天時間以言語創造了萬物,包括一切的活物。然後,上帝用了一天,按祂自己的形象,以地上的泥土用祂的手,造了人的模式,並在他的鼻孔吹入一口氣,有靈的活人便是如此造出來。這個人具備了上帝賜與的智慧與能力,所以人能管理整個世界。
	世界樣龐大,自然需要大量不同的人,才能完成整個管理工作。事實上,所有人都是平等。
	那麼人為什麼活著呢?可以分為兩大類理由:	
	●人當盡人在世上的責任,每一個人生存在世上一定負有不同的工作;此外,在人生的歷程中亦不斷承擔不同的身份。 	
	● 作為神的兒女,在神的國度裡亦當盡人子的責任。那麼人如何方能達到上帝的要求呢?每一個人的能力與意願上帝都好清楚,所以祂的要求很簡單:就是敬畏神,謹守祂的誡命,這是人所當盡的本分。


盡本分 	
	「生老病死」是人的必然,無可逃避。研究『死』的人不少,追尋死後何處去的人更多。雖然我曾經看過這一類專書,或者他們的見解太深奧,超越了我有限的思維。
	上文曾提到我有閱讀有關人體結構的參考書,記得其中有一篇是談到血液裡的血小板,我節錄了一些資料:當一個人受傷開始流血時,血小板會聚集起來「塞住」破洞,然後「自體瓦解」釋出化學物質啟動凝血作用。很明顯血小板一定有個訊息接收器,所以當人體某地方破損時,而人體總中樞發出指令之後,血小板便去「塞住」那破洞。與此同時又會釋出化學物質去凝固血液,所以血不會不停地再流。另一問題,就是血小板的壽命平均是五至十一天,隨時由骨髓補充。
	當日,看完了該書《人,美妙的傑作》關於血小板的介紹,我不得不停下來想一個問題:「當我受傷時,我有向血小板下達任何指令嗎?」當然很清楚我沒有這樣做,因為還只是那一刻我才認識血小板多一點點而已。	
魂 	
	究竟除了我之外,誰下指令呢?而我更加相信我那異常複雜的身體,可能每天都有些變化,而管控血小板那個總中樞,一定同樣地肩負著發出指令的任務,讓身體作出正常運作。我發現了原來除我以外,還有另外一個我,而這個『另外的一個我』比諸『我』更加瞭解『我』。 	
	在神學書裡面,神學家指人是有「靈魂」的,其中「靈」是與造物主連系,而「魂」是管控人體的運作。靈魂之說,我自認識血小板之後便深信不移。原來,人的肉體必然會毀滅,但靈魂不屬肉體,所以依然存在。 	
天國居所 	
	人死後何去呢?耶穌在經上說:「在我父的家裡,有許多住處。若是沒有,我就早已告訴你們了。我去原是為你們預備地方去。」(約翰福音十四:二)	
有歷練人生的人,相信對下列描繪會有強烈感受:	
	●人生有如白駒過隙,轉迅即逝。 	
	● 經上說:「我們一生的年日是七十歲,若是強壯可到八十,但其中所矜誇的,不過是勞苦愁煩,轉眼成空,我們便如飛而去。」(詩篇九十:十)環顧世界各地,不是戰爭,便是隨時一觸即發的戰爭,又或是政治的鬥爭,凡此種種,用『勞苦愁煩』來形容,可謂非常貼切,而人的生命轉瞬即逝,亦確實如此!如此日子確是帶來異常灰暗的人生。
	不過,相信你曾經到過各地旅遊,無論你所去何處,住什麼酒店,你祗是一個旅居他地的旅客,最後還是要回到你的老家。原來,我們今天所在的世界,只是旅居之地。聖經常常提醒我們,我們不過是一個『過客』。你的老家就是上文耶穌為你預備的地方。
	『信』,是人渴望擁有,但不容易得到的東西,聖經對『信』是這樣說:信就是「對所盼望的事的把握,是還沒有看見的事的明證。」(希伯來書十一:一)	
 	朋友:當你相信上帝是創造人和萬物的創造主時,那麼你便應相信上帝所給予我們的一切。 	(全文完)
神與我同在	
     陳翠華姊妹感恩見証分享	
你要以你的訓言引導我,以後必接我到榮耀裡。除你以外,在天上我有誰呢?除你以外,在地上我也沒有所愛慕的。我的肉體和我的心腸衰殘,但神是我心裡的力量,又是我的福分,直到永遠。(詩篇七十三:二十四至二十六)	
	
	二○二○年十月十八日星期日,吃過午飯後,我的先生如常一樣出去散步,然後午睡,起床後吃了酸牛奶,一切很正常。下午三點半左右,先生突然覺得有點冷,於是就穿上毛衣,但還是覺得很冷,就再穿上一件薄羽絨服。	
	過了一會兒,他開始全身發抖。我深知大事不妙,一定是發高熱了。果然一探熱是華氏三十七度六,於是馬上吃「TYLENOL」退燒藥,並上床休息。但蓋了被子還一直發抖。到了晚上七點多,再探熱是華氏三十八度六,怎麼辦好呢?星期天家庭醫生不開診,去醫院覺得不安全(因為前段時間公寓裡有老人去醫院後,反而感染了新冠病毒而去世)。怎麼辦呢?	
	記起聖經中上帝的話語:「你不要害怕,因為我與你同在;不要驚惶,因為我是你的上帝。我必堅固你,我必幫助你;我必用我公義的右手扶持你。」(以賽亞書四十一:十)神的話給了我力量,改變了我過去對疫病害怕、惶恐的心理,就馬上打電話通知孫女,她和男朋友立刻去藥房買了一種效力較強些的退燒藥送來。先生吃了一次強力退燒藥後,在午夜時,高熱開始退了一些,再吃了一次「TYLENOL」退燒藥後,天亮時就退熱了。	
	第二天起床後,發現先生的尿液顏色很深而量又少,我猜想可能是他的泌尿系統有問題。早上九點後,便打電話到家庭醫生診所,醫生聽到先生發過高熱,不論退熱已否,一定要去做病毒檢測。
	於是女兒和孫女很快就找到了一個檢測點,我們便飛車前去。來到檢測點,只見到工作人員,沒有見到一個要檢測的人,我們覺得很安全,害怕感染到病毒的恐懼,頓時消失了,很快就做完了檢測。回到家後,我便立刻聯繫了先生的泌尿科醫生,並約好了星期二上午九點見醫生,一切都很順利。	
	在星期一那一天,雖然沒有見到醫生,由於大量喝水,尿液增多了,顏色也淡了很多。星期二早上,得知病毒檢測的結果是陰性。見過泌尿科醫生,吃了消炎藥,情況好了很多。
	我很高興在這裡分享,因為我真是感受到神的恩典!先生從發高熱到退熱,尿液從少到增多,從尿液從濁到清,檢測到診病,一切都很順利。這就是神的恩賜!一切榮耀歸於神!

	        二○二二年七月九日

    Why axolotls seem to be everywhere — except in the one lake they call home
    kraken ссылка
    Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls.

    The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.”

    Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like.

    They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature.

    A scientific mystery
    Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used.
    Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.)

    Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water.

    Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.

    “They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”

    Axolotl problems
    As Mexico City grew and became more industrialized, the need for water brought pumps and pipes to the lake, and eventually, “it was like a bad, smelly pond with rotten water,” Zambrano said. “All of our aquatic animals suffer with bad water quality, but amphibians suffer more because they have to breathe with the skin.”
    лаки джет игра
    To add to the axolotls’ problems, invasive fish species such as carp and tilapia were introduced to the lake, where they feed on axolotl eggs. And a 1985 earthquake in Mexico City displaced thousands of people, who found new homes in the area around the lake, further contributing to the destruction of the axolotls’ habitat.

    These combined threats have devastated axolotl populations. According to the International Union for Conservation of Nature, there are fewer than 100 adult axolotls left in the wild. The species is considered critically endangered.

    While the wild axolotls of Lake Xochimilco have dwindled to near-extinction, countless axolotls have been bred for scientific laboratories and the pet trade. “The axolotl essentially helped establish the field of experimental zoology,” Voss said.

    In 1864, a French army officer brought live axolotls back to Europe, where scientists were surprised to learn that the seemingly juvenile aquatic salamanders were capable of reproduction. Since then, scientists around the world have studied axolotls and their DNA to learn about the salamanders’ unusual metamorphosis (or lack thereof) as well as their ability to regrow injured body parts.
    In addition to their role in labs, axolotls have become popular in the exotic pet trade (though they are illegal to own in California, Maine, New Jersey and Washington, DC). However, the axolotls you might find at a pet shop are different from their wild relatives in Lake Xochimilco. Most wild axolotls are a dark grayish brown. The famous pink axolotls, as well as other color variants such as white, blue, yellow and black, are genetic anomalies that are rare in the wild but selectively bred for in the pet trade.

    What’s more, “most of the animals in the pet trade have a very small genetic variance,” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. (Plus, the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.)

    Broken spheres
    Dyson died in 2020 before any of his spheres could be found — although they are just one of a dozen ideas that bear his name.

    “As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.”

    George Dyson also attested to his father’s fascination and comprehensive reach across disciplines.

    “Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’”

    The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study.

    “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.”

    “We got 53 candidates for anomalies that cannot be well explained, but can’t say that all of them are Dyson sphere candidates, because that’s not what we are specifically looking for,” said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo’s model to see how many tie into it.

    “You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere,” she added. “To do so you need to also rule out that it’s not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it’s a win-win.”

    Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA’s James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.
    If Dyson spheres really exist, what could they be used for? “If you picture ourselves having as much energy as the sun is providing every second, we could do unheard of things,” Suazo said. “We could do interstellar travel, maybe we could even move the entire solar system to our preferred location, if we wanted.”

    But don’t hold your breath, because the technology and the raw materials required to build the hypothetical structures are far beyond humanity’s grasp.

    “They are so big that everything we have on Earth would not be enough to build them,” Suazo added. “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”

    That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare.

    ‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence
    Кракен даркнет
    What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces.

    “One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star,” wrote Dyson in a 1960 paper in which he first explained the concept
    https://kra30c.cc
    kra31 cc
    If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker,” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey.
    Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.”

    In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered.

    “Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look,” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek,’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.”
