Cette découverte vient d’être faite dans les eaux du Pacifique. </strong> </p> <p> C’est aux environs des îles Salomon, dans une zone surnommée “Three Sisters” (ou Trois Soeurs en français) qu’un groupe de scientifiques du National Geographic est tombé sur le plus corail du monde, trois fois supérieure au précédent détenteur du record, indique le média <em> Demotivateur </em> . L'écologiste marin, Enric Sala, confie : </p> <p> <em> “Alors que nous pensions qu’il n’y avait plus rien à découvrir sur la planète terre, nous avons trouvé un corail massif composé de près d’un milliard de petits polypes, débordant de vie et de couleurs”. </em> </p> <p> L’équipe du National Geographic souligne que la structure autonome s’est développée durant près de 300 ans, partant d’un “réseau complexe” de minuscules polypes coralliens. Et de poursuivre : “elle se distingue d’un récif corallien, constitué de nombreuses colonies distinctes”. </p> <p> <strong> Comme une glace qui s’étend sur le fond marin </strong> </p> <p> Il s’agit-là du plus grand corail du monde, aux dimensions hors norme (supérieures à celles d’une baleine bleue). Dépassant le corail baptisé “Big Momma”, cette structure récemment découverte fait 34 mètres de large sur 32 de long. Molly Timmers, scientifique principale de l’expédition, précise : <em> “alors que Big Momma ressemblait à une énorme boule de glace posée sur le récif, ce corail nouvellement découvert est comme si la glace avait commencé à fondre, s’étalant indéfiniment sur le fond marin”. </em> </p> <p> Une nouvelle colonie que, selon les dires de la scientifique, serait observable desde l'espace. Le spécialiste des coraux, Eric Brown, a en outre précisé : <em> Étant donné que les récifs peu profonds à proximité ont subi des dommages en raison de la montée des températures océaniques, cet important écosystème coralien bien préservé dans des eaux un peu plus profondes représente un espoir. </em> </p> <p> (ASD - Source : Le Démotivateur - Illustration : Unsplash) </p> <div> <span data-embed-id="b26679ab2a7b487ca42cf7c0c255cf7a" data-embed-type="social-auto"> </span> </div> <p> <strong> <i> Assurez-vous de lire tous nos articles sur MSN en vous abonneant à nos contenus.

Geologists Probe Mysterious Sinkhole That Swallowed Vehicle in Hetauda - International Edition (English)

<img data-document-id="cms/api/amp/image/AA1Eex54" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1Eex54.jpg"/> <p> On Wednesday, a group of four geologists reached Hetauda with the aim of starting a field investigation in the region where a vehicle sank into the earth due to a road collapse five days prior. </p> <p> The event took place in Gairigaun, part of ward 16 within Hetauda Sub-metropolitan City, where the street collapsed on Friday, forming a muddy pit similar to a sinkhole. The car carrying fish has not been found since. </p> <p> The research project began following the request made by officials in a suburban city. It is being spearheaded by geologist Narayan Adhikari and comprises members including Krishna Pandey, Mani Khanal, and Amar Bahadur Thapa, who serves as a laboratory technician affiliated with the Department of Mines and Geology. To obtain specific insights into what occurred, the specialists interviewed driver Hareram Rai. Additionally, they sought initial geological data regarding the region from longtime resident Bhairav Rai. </p> <p> Owing to security issues, officials have prohibited any movement within a radius of 100 meters around the sinkhole. A geologist commented, “In this region, there used to be a lake, and the underlying soil consists of dark clay.” He further explained, “The collapse might have been triggered by either tectonic movements or well-drilling activities; however, we'll gain clearer insights following our investigation.” </p> <p> Mayor Mina Kumari Lama of Hetauda, along with Deputy Mayor Rajesh Baniya and council members representing different wards, attended the site visit. </p> <p> Witnesses stated that the car was stationary when the roadway unexpectedly collapsed, causing it to disappear rapidly. Although the driver and assistant managed to flee safely, the vehicle remains missing. Efforts to pump out water from the site have been unsuccessful in recovering the car so far. </p> <p> Following the incident, the Municipal Disaster Management Committee convened a meeting on Sunday, attended by Chief District Officer Scheme Shrestha. They resolved to delay restoration activities until geologists had evaluated the location. </p> <p> People residing near the area where the ground collapsed, such as the owner of an adjacent cement house, have shown concern over potential additional sinking. The location of the incident is near both a pond and a well-drilled hole for water extraction. Geologists believe that the overuse of underground water might be linked to this occurrence. </p>

「救世主」が「害獣」に。奄美大島のマングース根絶から考える、人間の責任

<p> <img data-document-id="cms/api/amp/image/AA1BvAic" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BvAic.jpg"/> </p> <p> 世界自然遺産に登録されている鹿児島県・奄美大島の生態系に、危機的な被害をもたらした外来種マングース。毒蛇ハブ対策の「救世主」として、半世紀近く前に野に放たれたが、希少な在来の動物を捕食したり、作物を食い荒らしたりすることが問題となり、一転して「害獣」として駆除の対象に。捕獲専門集団「マングースバスターズ」や関係者の、約３０年にわたる取り組みの結果、環境省は２０２４年９月、根絶を宣言した。 </p> <p> 東京２３区や琵琶湖より広いほどの面積の島で、長期間定着した後の根絶は例がなく、世界各地の外来種対策の参考事例になるとみられる。一方、天敵がいなくなったことで、個体数が回復した国の特別天然記念物アマミノクロウサギによる農業被害が拡大。希少種の保全管理のあり方が新たな課題となっている。 </p> <p> 人間の都合で連れてこられた末、生態系保護の名の下“絶滅”に追いやられたマングース。捕獲数は約３万２６００匹に上る。「世界的に類がない」（環境省）根絶達成に至る経緯をたどると、外来種問題と人間の身勝手さの、表裏一体の構図が見えてくる。（共同通信＝高槻義隆、渡具知萌絵） </p> <p> ※筆者が音声でも解説しています。「共同通信Podcast」でお聴きください。 </p> <p> <strong> ▽実は昼行性のマングース、夜行性のハブの天敵にはならず </strong> </p> <p> マングースはイタチに似た細長い体と短い四肢、長い尾が特徴の哺乳類だ。もともと日本にはおらず、ハブやそのエサとなるネズミの駆除を目的に１９１０年、現在のバングラデシュからフイリマングースという種類が沖縄本島に持ち込まれた。 </p> <p> 奄美大島には１９７０年代後半、沖縄本島から数十匹が連れてこられた。１９８３年１月１９日付の奄美地元紙・南海日日新聞によると、旧名瀬市（現奄美市名瀬）の北方の赤崎に「（昭和）５３年から５５年までの３年間に計３０匹のマングースを放し繁殖状況を見守ってきた」。記事では男性の実名入りで「ハブ対策と繁殖実験を兼ねて放した」と報じられている。 </p> <p> だが、人知の浅はかさが露呈する。マングースは昼間に行動する昼行性だ。一方、ハブは夜行性。そもそも両者が遭遇することはまれで、マングースはハブの天敵になどならなかったのだ。 </p> <p> すれ違い生活のハブの代わりにマングースのエサとなったのが、アマミノクロウサギやケナガネズミ、アマミイシカワガエルなどの希少な在来種だった。マングース導入は完全に裏目に出て、奄美の生態系は急激にバランスを崩し始めた。 </p> <p> <strong> ▽サツマイモ、ひな、ウサギ、被害拡大で脅かされる固有種 </strong> </p> <p> <img data-document-id="cms/api/amp/image/AA1BvCMC" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BvCMC.jpg"/> </p> <p> 放獣からまもなく、マングースによる被害が確認されるようになった。赤崎のある島北西部で、サツマイモやジャガイモ、スイカなど根菜類や地上で実を付ける作物はことごとく食い荒らされ、鶏舎からはひながさらわれた。 </p> <p> 農家は自衛策として箱わなを仕掛けて捕獲したが、すぐに手に負えなくなった。栽培する作物を根菜類から、マングースが食べない葉物に切り替えもしたが、侵入を防ぐための網やビニールハウスを破る乱行ぶりに、お手上げ状態だった。 </p> <p> 奄美におけるマングースの生息状況を、最初に調査したのは地元の奄美哺乳類研究会。１９９１年発行のリポートによると、奄美固有の野鳥で、国の天然記念物ルリカケスのひなを襲った目撃例があるとして「在来種個体群に対し、マングースが少なからず影響を与えている可能性がある」と指摘。国や県による駆除などの対応を求めた。 </p> <p> この頃、固有種の宝庫として知られる奄美市名瀬の金作原では被害が顕著になってきた。研究会メンバーで、環境省奄美群島国立公園管理事務所の阿部慎太郎さん（６１）は「マングースの分布が広がるにつれ、たくさんいたアマミノクロウサギなどが見られなくなった。これはまずいと思った」と振り返った。 </p> <p> <strong> ▽追いつかない捕獲 </strong> </p> <p> <img data-document-id="cms/api/amp/image/AA1BvF7j" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BvF7j.jpg"/> </p> <p> 赤崎地区がある旧名瀬市は１９９３年１０月、マングース捕獲者を募集し、駆除に乗り出した。島内の他町村も同調し、島を挙げた態勢となったが、課題は山積していた。マングースは当時の鳥獣保護法により保護動物扱いで、捕獲者を増やしても全体の捕獲数の上限があり、集めたマンパワーを生かし切れなかった。 </p> <p> また、１匹数千円での買い上げ方式のため、捕獲しやすい農作地帯でわなを仕掛ける人がほとんどで、個体密度が低い山の中に入ってまで捕る人はまれだった。捕獲開始当時の生息数は１万匹以上と推定されたが、繁殖数に捕獲数が追いつかない状態で、抑制どころか島全体へのまん延が懸念される状況となっていった。 </p> <p> <strong> ▽捕獲に注力できるように、バスターズ結成 </strong> </p> <p> <img data-document-id="cms/api/amp/image/AA1BvCMH" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BvCMH.jpg"/> </p> <p> 駆除開始から３年後の１９９６年、環境庁（当時）は奄美大島の生態系保全に向け、マングースの駆除や個体数制御に関するモデル設計に着手。２０００年度から本格的な防除事業が始まった。 </p> <p> 山中の駆除に向けた大きな一手が講じられたのは、外来生物法が施行された２００５年のことだった。捕獲者の待遇を、捕獲した個体を定額で買い取る報奨金制度から、一般財団法人の嘱託職員として月給を支払う雇用制度へと切り替えたのだ。捕獲数が少なくても、手取りは保障されるため、山中の活動に注力できる。マングースを駆除し、環境を元に戻すことを目標に結成されたのがバスターズだ。 </p> <p> ２００５年度から、環境省の防除事業を受託する一般社団法人自然環境研究センターが全国から募集し、１２人でスタート。２０１２年には最多の５４人が雇用された。 </p> <p> ２００７年からは、わなを避けるマングースを捕る探索犬を導入。バスターズの後藤義仁さん（４９）は「道なき道に高密度にわなをかけて見回ったり、探索犬とともに森や崖などを歩き回ったりした。ハブやハチと遭遇して被害に遭ったり、崖から転落しそうになったりした人もいる」と語る。 </p> <p> <strong> ▽わなに別の動物が…「混獲」問題を解決 </strong> </p> <p> <img data-document-id="cms/api/amp/image/AA1BvnNU" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BvnNU.jpg"/> </p> <p> マングースの捕獲が進み始めたことに伴い、個体数が回復してきた在来種がわなにかかってしまう「混獲」が増え始めた。問題となったのは捕殺用の筒わなだ。 </p> <p> エサを探すために、狭い所に頭を突っ込むマングースの習性を突いたもので、エサのにおいにつられて筒に頭を入れると、中のバネで首が挟まる。天然記念物のルリカケスをはじめアマミトゲネズミやケナガネズミなどが頻繁にかかってしまうようになった。 </p> <p> バスターズはわなの改良に着手。内部の仕掛けや筒の長さなどに試行錯誤を重ね、２００８年、在来種がかかりにくいわなが完成した。後藤さんは「希少種が捕獲されるのは本末転倒。みんなで考えた混獲対策のアイデアを技術のメンバーが形にしてくれた」と話す。 </p> <p> 駆除が進み、個体数が減少するに従って、２００２年から２００６年まで２千匹台だった捕獲数は２００７年から千匹以下に。２０１４年には百匹以下、２０１８年の１匹を最後に「捕獲ゼロ」が続き、根絶宣言に至った。 </p> <p> <strong> ▽「マングースを持ってこなかったら、マングースを殺さなくて良かった」 </strong> </p> <p> <img data-document-id="cms/api/amp/image/AA1BvAiv" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BvAiv.jpg"/> </p> <p> 自治体による駆除を含め、根絶までのマングース捕獲数は約３万２６００匹。環境省の対策事業費は計３５億７千万円に上る。マングース防除事業は沖縄本島で続いている一方、奄美大島では新たな外来種の侵入警戒に移っている。 </p> <p> 奄美群島国立公園管理事務所の阿部さんは「人がマングースを持ってこなかったら、たくさんのマングースや在来種を殺さなくてよかった。人が起こしたことの尻ぬぐいをバスターズがしてくれた。外来生物が起こした問題とその代償をきちんと考え、島の野生生物のあるべき姿を維持するためにこれからどうしたらいいか考えてほしい」と訴える。 </p> <p> 沖縄大の山田文雄客員教授（７２）によると、マングースは１９世紀にハワイやカリブ海の島々、アフリカの島などでネズミや毒ヘビ対策で導入され、奄美や沖縄同様、希少種の絶滅や生態系危機を引き起こした。「マングース根絶は難しく、奄美大島の事例は海外でも驚きと称賛をもって迎えられている」という。 </p> <p> 一方、アマミノクロウサギをはじめとする希少種の回復に伴い、交通事故や農業被害、居住地への侵入などの問題が新たに発生している。山田客員教授は「希少種が増えることで良いことも悪いことも起きる。行政も住民も、共存するために適切な保全管理策を取ってほしい」と願った。 </p>

Scientists Might Unveil a Game-Changing Alien Life Signature—but Big Hurdles Remain

<p> <img data-document-id="cms/api/amp/image/AA1BfzmI" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1BfzmI.jpg"/> </p> <p> The search for alien life is one of the most captivating scientific quests of our time. With the discovery of thousands of exoplanets, astronomers are now focused on identifying clear biosignatures—chemical indicators in planetary atmospheres that could reveal the presence of life. </p> <p> A recent study by researchers at the University of California, Riverside (UCR) , suggests that methyl halides could be one such biosignature. These gases, composed of one carbon and three hydrogen atoms bonded to a halogen, are naturally produced by bacteria, algae, fungi, and some plants on Earth, but they are not known to form through abiotic (non-biological) processes. </p> <p> This makes them a highly promising target in the search for life. However, there’s a significant obstacle: our current telescopes, including the James Webb Space Telescope (JWST), are not yet powerful enough to detect them in Earth-sized exoplanets. Researchers believe, however, that a different class of planets—Hycean worlds—could provide a solution. </p> <h2> What Are Methyl Halides and Why Do They Matter? </h2> <p> In the hunt for alien life , scientists rely on finding molecules that are primarily produced by biological organisms. Traditionally, gases such as oxygen, methane, and water vapor have been considered promising biosignatures, but they are not definitive proof of life since they can also be created through geological and atmospheric processes. </p> <p> <strong> Methyl halides, however, are different. </strong> These gases are released into Earth’s atmosphere by biological activity but are not known to be created through purely chemical or geological processes. This makes them particularly valuable as potential biosignatures. If methyl halides were detected in the atmosphere of an exoplanet, it could strongly suggest the presence of life. </p> <p> “Unlike an Earth-like planet, where atmospheric noise and telescope limitations make it difficult to detect biosignatures, Hycean planets offer a much clearer signal,” explains <strong> Eddie Schwieterman </strong> , an astrobiologist at UCR. </p> <p> The study suggests that <strong> Hycean planets </strong> , which are water-rich worlds orbiting <strong> red dwarf stars </strong> , may provide the ideal conditions for these gases to accumulate in detectable amounts. </p> <h2> Why Can’t We Detect These Biosignatures Yet? </h2> <p> The <strong> James Webb Space Telescope (JWST) </strong> has revolutionized exoplanet research by providing detailed observations of atmospheres, but even JWST has limits. </p> <p> ・Size Matters: Earth-sized exoplanets are too small and dim for JWST to observe directly. It can detect atmospheric signatures from larger gas giants, but analyzing smaller rocky planets remains a significant challenge. </p> <p> ・Signal Strength: Even if methyl halides exist in an exoplanet’s atmosphere, the concentration may be too low for JWST to detect using current techniques. </p> <p> ・Interference from Host Stars: Many promising exoplanets orbit red dwarf stars, which produce intense radiation and atmospheric noise that could obscure potential biosignatures. </p> <p> Because of these challenges, Schwieterman and his colleagues suggest that <strong> Hycean planets </strong> —which have thick hydrogen atmospheres and orbit dimmer red dwarf stars—could provide a better opportunity for detection. </p> <h2> Hycean Planets: A New Hope for Detecting Alien Life </h2> <p> Hycean planets are a relatively new category of exoplanets that astronomers believe could be more <strong> hospitable to microbial life </strong> than Earth-like planets. They are: </p> <p> ・Larger than Earth, but not as massive as gas giants </p> <p> ・Covered in global oceans, potentially resembling Earth’s early conditions </p> <p> ・Likely to retain biosignature gases, including methyl halides, in their thick atmospheres </p> <p> Because <strong> Hycean planets </strong> have thick atmospheres rich in hydrogen, they can allow methyl halides to accumulate in larger amounts than Earth-like planets, making them easier to detect with JWST and future space telescopes. </p> <p> If life exists on Hycean worlds, methyl halides could be one of the first biosignatures we detect beyond Earth. </p> <p> <strong> Enjoyed this article? </strong> Subscribe to our free newsletter for engaging stories, exclusive content, and the latest news. </p> <p> For more news like this, visit . </p>

Scientists Verify the Mind-Bending Reality of Time Mirrors

<img data-document-id="cms/api/amp/image/AA1A5hj3" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1A5hj3.jpg"/> <ul> <li> For over five decades, researchers hypothesized that an electromagnetic wave might experience time reversal—a phenomenon not limited to spatial reflection alone. </li> <li> Researchers haven't been able to verify the occurrence of time reflection because of the immense amount of energy needed to form a temporal boundary. </li> <li> For the first time, scientists in New York City managed to observe time reflections using a specially designed metamaterial. </li> </ul> <p> The concept of spatial reflections via light or sound is quite straightforward. When electromagnetic radiation such as light waves encounter a mirror or when sound waves strike a wall, they alter their direction. Consequently, this enables our eyes to perceive a reflected image or our ears to hear an echoed version of the initial input. Nonetheless, for over half a century, scientists have theorized That there exists another form of reflection in quantum mechanics called time reflection. </p> <p> This word could evoke visions of a nuclear-powered DeLorean Or perhaps you're thinking of a specific police box (which is larger internally than externally), but that concept isn’t exactly what scientists refer to as "time reflections." Rather, these phenomena happen when the whole medium through which an electromagnetic wave propagates abruptly alters direction. As a result, part of this wave flips backward, causing its frequency to shift into a different one. </p> <p> Since these temporal reflections necessitate a consistent change throughout an entire electromagnetic field, experts presumed that generating enough energy to witness them directly would be impractical. However, researchers affiliated with the CUNY Graduate Center’s Advanced Science Research Center (CUNY ASRC) located in New York City have explored this phenomenon. successfully observed Time reflections achieved by transmitting broad spectrum signals through a metallic strip embedded with electronic switches linked to storage capacitors. </p> <p> This enabled the scientists to activate the switches as needed, which doubled the resistance along the strip. This abrupt alteration led to the signals transmitting a successfully reversed-time version. The findings were documented in the journal. <em> Nature Physics </em> . </p> <p> It’s extremely challenging to alter the characteristics of a medium rapidly, evenly, and with sufficient temporal resolution for reflecting electromagnetic waves since these waves oscillate very quickly," stated Gengyu Xu, a co-author and post-doctoral researcher at CUNY ASRC, in a press release. "We conceived an approach where we wouldn’t modify the inherent qualities of the main material; rather, our plan involves constructing a metamaterial featuring supplementary components that can swiftly be introduced or removed via rapid switching mechanisms. </p> <p> This time reflection operates differently compared to spatial reflections. Since this time echo bounces back the latter portion of the signal initially, the researchers indicate that if one were to look into it, <em> time </em> If you looked into it, the mirror would reflect your back rather than your face. In sound terms, this would be similar to hearing a cassette being played backwards—meaning at a faster speed and higher pitch. </p> <p> If we were able to see changes in frequency with our eyes, it would appear as though hues of light abruptly transform from one color to another, for instance, shifting from red to green. The peculiar and non-intuitive behavior of time reflection contributes significantly to the challenges faced when exploring this idea. </p> <p> “It has been truly thrilling to witness this, considering how far back in time this unexpected effect was first theorized, and the stark differences between time-reversed waves and those reflected in space,” stated corresponding author Andrea Alù, a physics professor and director of CUNY ASRC’s Photonics Initiative, in an official release. </p> <p> The big question: <em> W </em> <em> hy </em> Have researchers endeavored to replicate this hypothetical time reversal phenomenon in a lab setting? Better manipulation of electromagnetic waves could significantly enhance wireless communication systems and potentially pave the way for innovations in low-power, waveform-driven computing technologies. </p> <p> To put it differently, it essentially aids in understanding all aspects of electromagnetic waves—not just one way but both directions. </p> <h2 class="body-h2"> The 2023 Popular Mechanics Automotive Excellence Awards: Electric Vehicles </h2> <img data-document-id="cms/api/amp/slideshow/AA149qTW" data-reference="slideshow"/>

El hallazgo de un antiguo glaciar revela pistas sobre cómo evolucionó la vida compleja en la Tierra, según los científicos

<p> Hace más de 500 millones de años, en una Tierra gélida y cubierta de hielo, los glaciares agitaron los ingredientes de la vida compleja al arrasar los minerales terrestres y depositarlos después en el océano, según un nuevo estudio. </p> <p> Centímetro a centímetro, a medida que los enormes glaciares se arrastraban sobre la tierra helada hacia un mar cubierto de hielo, escarbaban el suelo bajo ellos, excavando y raspando rocas de la corteza terrestre. Cuando los glaciares acabaron derritiéndose, liberaron en el océano un torrente de sustancias químicas terrestres, según informaron recientemente los investigadores. Los minerales arrastrados a tierra por esta “escoba glaciar” alteraron la química marina e infundieron a los océanos nutrientes que, según dicen, pueden haber determinado la evolución de la vida compleja. </p> <p> Este antiguo periodo de heladas profundas, conocido como la era Neoproterozoica , o “Tierra bola de nieve”, duró desde hace unos 1.000 millones a 543 millones de años. </p> <p> Durante ese tiempo, las masas de tierra se consolidaron en un supercontinente llamado Rodinia y luego volvieron a separarse. Las primeras formas de vida de la Tierra, como los microbios, las cianobacterias, las esponjas y los organismos que habitaban los fondos marinos, poblaron los océanos. Tras el final del Neoproterozoico llegó el auge de la vida más compleja, con la primera aparición de criaturas marinas que lucían armaduras, caparazones y púas. </p> <p> Los científicos han atribuido este auge evolutivo al aumento de los niveles de oxígeno en la atmósfera terrestre y en las aguas poco profundas de los océanos. Y ahora, una investigación publicada el martes en la revista académica Geology Propone que el movimiento de los glaciares antiguos pudo haber modelado directamente modificaciones químicas en los océanos, las cuales fueron cruciales para la evolución de organismos más complejos. </p> <p> El análisis de la "Tiempos glaciares" proporciona un vistazo al historial climático terrestre y brinda importantes insights sobre los cambios climáticos actuales, señaló el investigador principal del estudio, el Dr. Chris Kirkland. </p> <p> “Nuestro registro geológico en tiempo profundo indica cómo el cambio de una parte de la Tierra afecta a otra”, afirmó. Ahora mismo, el dramático calentamiento del planeta que marca la crisis climática provocada por el ser humano se está produciendo a una velocidad vertiginosa en comparación con estos antiguos procesos que duraron millones de años. </p> <p> Esta velocidad incrementada reduce la habilidad del planeta para equilibrarse por sí mismo de manera natural, destacando así la importancia crucial de enfrentar el calentamiento global provocado por humanos. </p> <h3> <strong> De la Tierra bola de nieve al planeta invernadero </strong> </h3> <p> Se conoce que el desplazamiento de los glaciares, conocido como glaciarización, lleva consigo y traslada sedimento continental hacia los océanos, lagunas y arroyos, sentando así las bases para las cadenas tróficas acuáticas. No obstante, aquellos científicos dedicados al estudio del planeta prehistórico carecían hasta ahora de certezas sobre si los glaciares neoproterozoicos tenían algún tipo de movimiento, incluso menos aún sabían si eran capaces de moverse lo bastante como para erosionar el lecho rocoso debajo de ellos e introducir minerales en el mar. </p> <p> "La teoría sugerida era que la extensa erosión glacial en las áreas internas del continente pudo deberse al hielo de una 'Tierra bola de nieve'", aclara Kirkland, quien es profesor en la Facultad de Ciencias Planetarias y Terrestres de la Universidad Curtin en Perth, Australia. "No obstante, ciertos detalles de esa suposición eran confusos debido a que este hielo tal vez no se desplazó mucho o simplemente fluyó". </p> <img data-document-id="cms/api/amp/image/AA1zRUlm" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1zRUlm.jpg"/> <p> Kirkland y sus colegas encontraron respuestas en Escocia e Irlanda del Norte, donde estudiaron sedimentos de formaciones rocosas que datan del Neoproterozoico. El equipo se fijó en los zircones, minerales cristalizados que son excepcionalmente duraderos y pueden resistir acontecimientos geológicos extremos. Los zircones también contienen uranio; al medir las etapas de la desintegración del uranio en los zircones, los geólogos utilizan los minerales como cronómetros para estudiar el pasado de la Tierra. </p> <p> Los investigadores examinaron sedimentos que databan de la época en que la Tierra estaba cubierta de hielo y del periodo de la “Tierra invernadero”, millones de años después, cuando el hielo desapareció, y descubrieron que la composición mineral de los sedimentos de la “Tierra bola de nieve” difería drásticamente de la de los sedimentos posteriores. </p> <p> “Recuperamos patrones distintivos en las poblaciones de estos granos minerales”, dijo Kirkland a CNN en un correo electrónico. “En esencia, la huella dactilar del ‘ADN’ de estas rocas sedimentarias cambió”. </p> <p> Los hallazgos parecen reforzar “en cierta medida” la noción de glaciación activa, afirmó el Dr. Graham Shields, profesor de Geología del University College de Londres. Shields no participó en la nueva investigación. Sin embargo, el estudio no incluyó datos de un intervalo glaciar significativo llamado Marinoan , que marcó el final de la “Tierra bola de nieve”, dijo a CNN en un correo electrónico. Shields también se mostró cauto a la hora de vincular directamente la erosión glaciar con la evolución de la vida compleja. </p> <p> “Esta conexión se ha propuesto antes, pero es controvertida porque el vínculo se asume en lugar de explicarse”, dijo Shields. “Un cambio drástico del paisaje que provoque la aparición de animales macroscópicos es una idea estupenda, pero el artículo introduce una hipótesis sobre la erosión glaciar/el clima que puede ponerse a prueba, en lugar de zanjar el debate”. </p> <h3> <strong> El deshielo masivo de los glaciares transforma los océanos </strong> </h3> <p> Las rocas de la época de la “Tierra bola de nieve” contenían minerales más antiguos, pero también presentaban un abanico de edades minerales, lo que insinuaba que las rocas quedaron expuestas y se erosionaron con el tiempo por el movimiento de raspado de los glaciares. </p> <p> Estas pruebas indicaron a los científicos que los glaciares del Neoproterozoico eran móviles. Las rocas más jóvenes, de cuando la “Tierra bola de nieve” se estaba descongelando, tenían un rango más estrecho de edades minerales, y los granos más frágiles estaban ausentes, lo que sugería que el agua que fluía había disuelto material que antes estaba molido. </p> <p> En el ocaso del Neoproterozoico, uno de los cambios conocidos en la química oceánica fue un aumento del uranio. Otras investigaciones habían explicado anteriormente este aumento como resultado del incremento del oxígeno atmosférico, “sin embargo, nuestros datos implican que el aporte de elementos químicos a los océanos también desempeñó un papel en ello”, dijo Kirkland. </p> <p> “El componente disuelto ‘perdido’ en estas rocas se ve ‘reaparecer’ en los cambios de la química oceánica en este momento”, añadió. Al cartografiar estos cambios en los entornos terrestres y marinos, “estamos obteniendo imágenes de la transferencia de elementos químicos a través de la Tierra como sistema”. </p> <p> Los científicos informaron que se produjeron grandes glaciaciones al menos dos veces entre hace 720 millones y 635 millones de años. A finales del Neoproterozoico, cuando la cubierta helada de la Tierra comenzó a descongelarse, se estaban produciendo importantes cambios químicos en la atmósfera y los océanos de la Tierra. </p> <p> “El final de estas glaciaciones está marcado por un rápido aumento del oxígeno atmosférico y oceánico, posiblemente debido a una mayor meteorización de las superficies rocosas expuestas y a un mayor flujo de nutrientes hacia el océano”, explicó Kirkland. Tales cambios podrían haber infundido ciclos de nutrientes y proporcionado a la vida emergente el impulso que necesitaba para evolucionar hacia formas más complejas. </p> <p> “La idea de que los restos glaciares de las eras glaciares del Neoproterozoico proporcionaron nutrientes para apoyar la evolución animal primitiva existe desde hace tiempo”, afirmó el Dr. Andrew Knoll, profesor emérito de Ciencias de la Tierra y Planetarias de la Universidad de Harvard, que no participó en la nueva investigación. Sin embargo, sigue habiendo dudas sobre si los minerales vertidos en el océano por la glaciación neoproterozoica habrían sido suficientes para provocar cambios medioambientales a largo plazo con consecuencias biológicas, dijo Knoll a CNN en un correo electrónico. </p> <p> Otras investigaciones sugirieron anteriormente que los impactos de los fenómenos de glaciación, como los descritos en el nuevo estudio, “bien podrían tener solo consecuencias transitorias: un bolo de nutrientes que eleva la producción primaria y tal vez aumenta los niveles de oxígeno, antes de volver al estado anterior del medio ambiente”, dijo Knoll. Los nuevos hallazgos son “una interesante adición a la conversación”, añadió. “Pero la conversación continúa”. </p> <h3> <strong> Lecciones para la crisis climática actual </strong> </h3> <p> Desde el Neoproterozoico hasta el presente, procesos similares configuran el cambio climático, incluido el papel desempeñado por el dióxido de carbono (CO2) y el comportamiento de los bucles de retroalimentación, cuando un proceso se alimenta de un aspecto existente del sistema climático de la Tierra y lo intensifica. </p> <p> Las pruebas climáticas antiguas también arrojan luz sobre lo que ocurre durante los puntos de inflexión climáticos, es decir, cuando se cruza un umbral que desencadena cambios a gran escala que suelen ser irreversibles. </p> <p> En la actualidad, la Tierra se está calentando rápidamente en lugar de enfriarse gradualmente a lo largo del tiempo. Hicieron falta millones de años para que la glaciación se apoderara del planeta durante la fase de bola de nieve de la Tierra, mientras que el calentamiento moderno se está acelerando en apenas unas décadas, “mucho más rápido que los cambios climáticos naturales del pasado”, afirmó Kirkland. </p> <p> Sin embargo, el avance global del cambio climático se sigue trazando estudiando la interacción de la acumulación de CO2, los bucles de retroalimentación y los puntos de inflexión, añadió. </p> <p> Observamos cómo diversas regiones del mundo se encuentran conectadas mediante relaciones químicas," expresó. "Cuando alteras un componente del sistema, el resto también experimenta cambios. </p> <p> Mindy Weisberger se desempeña como periodista científica y productora multimedia, habiendo publicado sus trabajos en plataformas como Live Science, Scientific American y la revista How It Works. </p> <p> Para obtener más noticias y boletines de CNN, crea una cuenta aquí.

Should We Revisit What NASA’s Viking Lander Discovered on Mars in 1976?

<p> In 1976, the two NASA Viking landers reached a halt on Mars. </p> <p> Their life detection experimental findings continue echoing throughout the scientific community — sparking an ongoing debate about a crucial question: Does life exist on Mars? </p> <p> Today, a fresh study revisits and reassesses the outcomes of the Viking Biology experiments. </p> <img data-document-id="cms/api/amp/video/AA1A5HGz" data-reference="video"/> <h2 id="perchlorate-finding"> Perchlorate finding </h2> <p> The most notable alteration following those 1970s experiments was the identification of elevated amounts of perchlorate on Mars Perchlorates along with non-biological oxidizers account for the findings of the Viking missions, thus eliminating the necessity to assume the presence of life on Mars. </p> <p> The recently published paper observes that “the finding of perchlorate on Mars by the Phoenix mission offers an explanation for the outcomes recorded by the Viking Lander missions. The thermal breakdown of perchlorates within the instruments' ovens could account for the absence of organic compounds detected. Additionally, the buildup of hypochlorite in Martian soil may also play a role.” cosmic ray The decomposition of perchlorate could account for the observed reactivity when nutrient solutions were introduced into the soil during the Viking Biology Experiments. </p> <p> The document also notes, "a non-biological interpretation of the Viking findings does not rule out the presence of life on Mars." </p> <h2 id="revisit-the-results"> Revisit the results </h2> <p> The recently published paper titled "Revisiting the Viking Biology Experiments on Mars" has been written by prominent Mars researchers. Christopher McKay Richard Quinn and Carol Stoker, both from the science division of NASA's Ames Research Center located near San Francisco at Moffett Field, California, along with a third author, have collaborated on this work. </p> <p> The potential for upcoming Mars sample returns and future missions, possibly incorporating life-detection tools, prompts us to reconsider the outcomes of the Viking biology experiments," propose the researchers. "Although much has evolved since Viking touched down on Mars, certain aspects remain constant. One such unchanging factor over the last half-century is our comprehension of how life operates under frigid and arid conditions. </p> <p> In communications with Christopher McKay, he mentioned <em> </em> It should be emphasized that our findings from the Viking mission do not indicate conclusively either the absence of life on Mars nor confirm its presence. </p> <p> McKay stated that their main argument revolves around the idea that the Viking mission detected perchlorates and other oxidizing agents on Mars, "which were responsible for the responses observed in the Viking biological tests." </p> <p> This implies that the outcomes from the Viking Biology experiments cannot be employed to support a strategy for ensuring astronauts' health and safety, nor to establish policies regarding the quarantine of samples and/or astronauts upon their return to Earth, under the assumption that there is no life on Mars. </p> <img data-document-id="cms/api/amp/image/AA1A5HGu" data-reference="image" src="https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1A5HGu.jpg"/> <h2 id="new-data"> New data </h2> <p> In their article published in the scientific journal *Icarus*, the three researchers highlight significant alterations due to missions sent to Mars. They state, "Undoubtedly, the most crucial novel information comes from the unexpected findings made by the Phoenix Mission They point out that Martian soil contains approximately 0.5% perchlorate. This extremely high level of perchlorate remains poorly understood; however, it has significant implications for the findings from the Viking missions. </p> <p> In their publication, the researchers state that the findings regarding the perchlorate model and the subsequent inference that Viking failed to detect life in Martian surface soils will play a role in discussions about future missions involving sample returns or human expeditions to Mars. </p> <p> The Outer Treaty bans 'harmful alterations to Earth’s environment due to the addition of extraterrestrial substances,' " McKay and his team point out. They also emphasize that additional experiments are crucial for gaining deeper insights into the chemistry of Martian soil and the potential existence of life on Mars. </p> <h2 id="good-targets"> Good targets </h2> <p> To summarize their research paper, they conclude that the perchlorate model for the Viking results "fails to confirm the absence of life." life on Mars , nor does it suggest that the ongoing quest for signs of life on Mars, whether in the past or present, is futile." </p> <p> Certainly, as proposed by the research team, they firmly advocate for seeking evidence of current life in upcoming missions. Ideal locations include salt deposits and polar surface ice. </p> <p> This latest study has been published in Icarus . </p>
