When you find like-minded artists who appreciate each other's talents, you have a winning combination. Sometimes it’s the accident that makes the music. It’s called working with what you have.   BIOGRAPHIES::  SON LUX BIO: From the start, Son Lux has operated as something akin to a sonic test kitchen. The Academy Award® and BAFTA-nominated band strives to question deeply held assumptions about how music is made and reconstruct it from a molecular level. What began as a solo project for founder Ryan Lott expanded in 2014, thanks to a kinship with Ian Chang and Rafiq Bhatia too strong to ignore. The trio strengthened their chemistry and honed their collective intuition while creating, releasing, and touring six recordings, including Brighter Wounds (2018) and the triple album Tomorrows (2021). The result is a carefully cultivated musical language rooted in curiosity and balancing opposites that largely eschews genre and structural conventions. And yet, the band remains audibly indebted to iconoclastic artists in soul, hip-hop, and experimental improvisation who themselves carved new paths forward. Distilling these varied influences, Son Lux searches for an equilibrium of raw emotional intimacy and meticulous electronic constructions. Son Lux has most recently scored the new Daniels film for A24, Everything Everywhere All at Once (March 2022). The full score album features new collaborations with Mitski, David Byrne, Randy Newman, and Moses Sumney, among others. Based in New York, Rafiq Bhatia is the first-generation American son of Muslim immigrant parents who trace their ancestry to India through East Africa. Early influences such as Jimi Hendrix, John Coltrane, and Madlib—as well as mentors and collaborators including Vijay Iyer and Billy Hart—prompted him to see music as a way to actively shape and represent his own identity, not limited by anyone else’s prescribed perspective. When Ian Chang describes his creative process, the phrase "third culture” keeps coming up. Born in the colony of Hong Kong in 1988, Chang has lived a nomadic life. Stationed out of New York for ten years and since relocated to Dallas, Texas, he built an impressive roster of progressive pop collaborators such as Moses Sumney, Joan As Policewoman, and Matthew Dear, among others, all while performing internationally and recording as a member of Son Lux and Landlady. Ryan Lott makes his home in Los Angeles but grew up all over the United States. Music was the one constant in his formative years spent at the piano. In addition to an extensive career writing music for dance, he has become a sought-after composer for advertising, television, and film. Lott’s feature film credits include The Disappearance of Eleanor Rigby (2014), Paper Towns (2015), and Mean Dreams (2017). He has co-produced and co-written music for and with Woodkid, Sufjan Stevens, and Lorde.   BIOGRAPHY: QASIM NAQVI  Qasim Naqvi is a drummer and founding member of Dawn of Midi.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.21.305797v1?rss=1 Authors: Kondapuram, M., Frieg, B., Yueksel, S., Schwabe, T., Sattler, C., Lelle, M., Schweinitz, A., Schmauder, R., Benndorf, K., Gohlke, H., Kusch, J. Abstract: Hyperpolarization-activated and cyclic nucleotide (HCN) modulated channels are tetrameric cation channels. In each of the four subunits, the intracellular cyclic nucleotide-binding domain (CNBD) is coupled to the transmembrane domain via a helical structure, the C-linker. High-resolution channel structures suggest that the C-linker enables functionally relevant interactions with the opposite subunit, which might be critical for coupling the conformational changes in the CNBD to the channel pore. We combined mutagenesis, patch-clamp technique, confocal patch-clamp fluorometry, and molecular dynamics simulations to show that residue K464 of the C-linker is essential for stabilizing the closed state of the mHCN2 channel by forming interactions with the opposite subunit. MD simulations revealed that both cAMP and K464E induce a rotation of the intracellular domain relative to the channel pore, weakening the autoinhibitory effect of the unoccupied CL-CNBD region. The adopted poses are in excellent agreement with structural results. Copy rights belong to original authors. Visit the link for more info

Great share from @_houseandgarden archive: Vita Sackville-West at Sissinghurst (1950). If you are renovating or starting from scratch - read this & be inspired! "The place had been in the market for three years since the death of the last farmer-owner... Brambles grew in wild profusion; bindweed wreathed its way into every support; ground-elder made a green carpet; docks and nettles flourished; couch­ grass sprouted; half the fruit trees in the orchard were dead; the ones that remained alive were growing in the coarsest grass; the moat was silted up and so invaded by reeds and bulrushes that the water was almost invisible; paths there were none, save of trodden mud. It had its charm. It was Sleeping Beauty's castle with a ven­geance — if you liked to see it with a romantic eye. But, if you also looked at it with a realistic eye, you saw that Nature run wild was not quite so romantic as you thought, and entailed a great deal of laborious tidying up. The most urgent thing to do was to plant hedges. We were extravagant over this, and planted yew, and have never regretted it. Everybody told us it took at least a century to make a good yew hedge, but the photographs will, I think, disprove this: the hedge is now only seventeen years old, a mere adoles­cent, and, at the end where the ground slopes and it has been allowed to grow up in order to maintain the top-level, it is 16 feet high. At the end of all this is the herb garden, which always seems to allure visitors, no doubt because it is a secret, senti­mental little place. "Old world charm" is the phrase I always expect to hear, and nine times out of ten, I get it. But, less romantic­ally, the herb garden does supply very useful things to the kitchen. One needs years of patience to make a garden; one needs deeply to love it in order to endure that patience. One needs optimism and foresight. One has to wait. One has to work hard oneself, sometimes, as I had to work hard, manually, during the war years, cutting all those hedges with shears in my spare time. I hated those hedges when I looked at my blistered hands, but at the same time, I still felt that it had been worthwhile planting them. They were the whole pattern and design and anatomy of the garden, and, as such, was worth any trouble I was willing to take.”   Now, if you'd like to check out these curated articles for yourself, you're in luck, because I share all of it with the Listener Community in the Free Facebook Group - The Daily Gardener Community.

Banks is best known for his study of Australian flora and fauna and his role as the botanist on board the Endeavor with Captain James Cook. When they landed in Australia, neither Cook nor Banks realized that the quartz reef where they planted the British Flag contained gold. The area would remain untouched by Europeans for almost two more decades. Before returning to England, Cook worried the Endeavor wouldn't make it around the Cape of Good Hope. In a fateful decision, Cook had brought the ship to Batavia, a Dutch colony, to fortify his boat. Batavia was a dangerous place where malaria and dysentery were rampant. As a result of his stop, Cook lost a staggering 38 members of his crew. Banks, and a fellow botanist Daniel Solander, managed to survive the stop, although, at one point, they were both gravely ill. Even as they battled back from illness, they still went out to collect specimens. As gardeners, we owe a great debt to Banks. When he returned to England, it was Joseph Banks who advised George III on the creation of the Royal Botanic Garden, Kew. And, in 1778, when Linnaeus died, his belongings went up for sale. By then, Joseph Banks was the President of the Linnean Society. Joseph acted quickly, buying everything of horticultural value on behalf of the society. Linnaeus' notebooks and specimens were on a ship bound for England by the time the king of Sweden realized Linnaeus' legacy was no longer in Sweden. He sent a fast Navy ship in pursuit of Banks' precious cargo, but it was too late. And so, Banks secured the legacy of Linnaeus, which is why Linnaeus's collection is in London at the Linnaeus Society's Burlington House. And, Banks helped spread Linnaeus's ideas across the globe, which was easier for him to accomplish since he was based in London, the hub for the science of botany. At his London residence, Banks hired the Scottish botanist Robert Brown to be his botanical librarian. The two became lifelong friends. So much so, that when Banks died in 1820, he left his home, his collections, and his library to Brown, and he also endowed him with a sizeable yearly allowance.   1780Today is the birthday of the Moravian clergyman and botanist Lewis David von Schweinitz, also known as the "Father of North American Mycology." Mycology is the study of fungi. Lewis was born in Pennsylvania, and he was a descendant on his mother's side of Count Zinzendorf - the founder of the Moravian Church. Lewis's home town of Bethlehem Pennsylvania was a Moravian settlement. When Lewis was seven years old, he was placed in a Moravian boarding school called Nazareth Hall. One of Lewis's earliest memories was visiting Nazareth Hall before attending there. He passed by one of the classrooms and saw a specimen of lichen digitatus sitting on a table, and he went to inspect it. It was Lewis's first experience with botany, and it would become his favorite subject. After completing his education, Lewis moved to Niesky, Germany, with his family. He was 18 years old. In Germany, Lewis became a pastor, got married, and studied botany in his spare time. He even managed to help his professor put together a book featuring over 1,000 different types of fungi found in Niesky. Lewis used his natural talent for drawing and painting to created watercolors of the specimens featured, and they are now digitized and available online. After many years in Germany, Lewis and his wife moved back to the United States to lead a Moravian church. They settled in Salem, North Carolina. Although the church was his primary focus, throughout his adulthood, Lewis devoted all of his spare time to the study of fungi. Between 1812 and 1821, Lewis collected in and around Salem North, Carolina. He was essentially replicating the work he had performed in Germany under the direction of his botany professor. In 1818, Lewis published his work on the fungi of North Carolina. Then, four years later, in 1822, Lewis published an even more comprehensive book featuring a staggering 3,000 species of fungi. In all, Lewis single-handedly published over 1,200 new species of fungi. When Lewis died, his enormous herbarium made its way to the Academy of Natural Sciences in Philadelphia. And here's a fun side note that pertains to Lewis Schweinitz: In 1986, botanists discovered the rare sunflower named for Lewis Schweinitz - the Schweinitz sunflower (Helianthus schweinitzii) near Rock Hill in South Carolina. The Schweinitz sunflower exists only in about a dozen little pockets around Rock Hill and Charlotte. Lewis, himself, initially discovered the Schweinitz sunflower in 1821.   1822 On this day, Jeremiah Bailey of Chester county, Pennsylvania, patented the first practical lawnmower; it had two wheels and was pulled by a horse. A person could mow up to ten acres a day with Bailey's machine. After locals trialed the device, they reported, “We consider it as one of the most complete and useful labor-saving machines for agricultural uses hitherto invented...” The first genuinely successful machine would be patented ten years later by Obed Hussey of Maryland.   Unearthed Words 1825 Today is the birthday of the heartfelt American poet and writer - known at Rutland's poet and Vermont's unofficial poet laureate - Julia Dorr. As a girl, her pseudonym was Flora or Florillla. The poet William Cullen Bryant once read one of her poems and wrote to tell her how much he loved the beauty of its imagery. And Ralph Waldo Emerson visited her and included one of her poems - called Outgrown - in his book called Parnassus. As you hear today's poems, imagine Julia Dorr writing in her little study next to the parlor. She had a window by her desk that overlooked her flower garden, which she called "her refuge and her inspiration."   Roly-poly honey bee, Humming in the clover, Under you, the tossing leaves And the blue sky over, Why are you so busy, pray? Never still a minute, Hovering now above a flower.  Now half-buried in it! — Honeybee   And all the meadows, wide unrolled,  Were green and silver, green and gold,  Where buttercups and daisies spun  Their shining tissues in the sun.  — Unanswered   I know a spot where the wild vines creep,  And the coral moss-cups grow,  And where at the foot of the rocky steep,  The sweet blue violets blow. —Over the Wall   And the stately lilies stand Fair in the silvery light,  Like saintly vestals, pale in prayer;  Their pure breath sanctifies the air,  As its fragrance fills the night. — A Red Rose   Often I linger where the roses pour  Exquisite odors from each glowing cup;  Or where the violet, brimmed with sweetness o'er,  Lifts its small chalice up.  — Without and Within   Plant a white rose at my feet,  Or a lily fair and sweet,  With the humble mignonette And the blue-eyed violet. — Earth to Earth   Around in silent grandeur stood  The stately children of the wood;  Maple and elm and towering pine  Mantled in folds of dark woodbine. — At the Gate   Meadow-sweet or lily fair— Which shall it be? Clematis or brier-rose, Blooming for me? Spicy pink, or violet With the dews of morning wet, Sweet peas or mignonette— Which shall it be? Blue-bells and yellow-bells Swinging in the air; Purple pansies, golden pied; Pink-white daisies, starry-eyed; Gay nasturtiums, deeply dyed, Climbing everywhere. Life is so full, so sweet— How can I choose? If I gather this rose, That I must lose! All are not for me to wear; I can only have my share; Thorns are hiding here and there; How can I choose? — Choosing   O my garden! Lying whitely in the moonlight and the dew, Far across the leagues of distance flies my heart to-night to you, And I see your stately lilies In the tender radiance gleam With a dim, mysterious splendor, like the angels of a dream! I can see the trellised arbor, and the roses crimson And the lances of the larkspurs all glittering, row on row, And the wilderness of hollyhocks, where brown bees seek their spoil, And butterflies dance all day long, in glad and gay turmoil. — Homesick   My true love sent me a valentine  All on a winter's day,  And suddenly the cold gray skies  Grew soft and warm as May!  The snowflakes changed to apple blooms,  A pink- white fluttering crowd,  And on the swaying maple boughs  The robins sang aloud.  For moaning wintry winds, I heard  The music sweet and low  Of morning-glory trumpets  Through which the soft airs blow.  O love of mine, my Valentine!  This is no winter day —  For Love rules all the calendars,  And Love knows only May! —An Answer To A Valentine    Julia died just before her 88th birthday in 1913. In Evergreen Cemetery, in Rutland, Vermont, Julia shares a tombstone with her husband, Seneca. The stone features her poem "Beyond." For your understanding, a barque is a ship with three masts. Beyond the sunset's crimson bars,  Beyond the twilight and the stars,  Beyond the midnight and the dark,  Sail on, sail on, O happy barque.  Into the dawn of that Tomorrow  Where hearts shall find the end of sorrow  And Love shall find its own! — Beyond   Grow That Garden Library A Sting in the Tale by Dave Goulson The subtitle of this book is My Adventures with Bumblebees. Dave's book is fascinating, and it will change the way you think about bumblebees. When he was a little boy, Dave became obsessed with wildlife. Although he grew up with a menagerie of pets, bumblebees were his passion. I thought you would enjoy hearing a few excerpts from Dave's book. Here's where he talks about the biology of the Bumblebee: “They have to eat almost continually to keep warm; a bumblebee with a full stomach is only ever about forty minutes from starvation. If a bumblebee runs out of energy, she cannot fly, and if she cannot fly, she cannot get to flowers to get more food, so she is doomed.” Then, here's where Dave tells us what we can do to help the Bumblebee. The answer for gardeners is a pretty simple one. Dave writes: “The key to helping our rarer species to thrive is probably simply to add more flower patches to the landscape, making it a little easier for them to find food and keep their nests well provisioned.” And Dave is hopeful about the future of the Bumblebee And about the impact that each of us can have on their survival. He writes: “Conserving bumblebees is something anyone can do. A single lavender bush on a patio or in a window box will attract and feed bumblebees, even in the heart of a city." And I love that Dave includes this fantastic quote from Andrew Downing, the 19th-century American horticulturist. “The music of the busy bee Is drowsy, and it comforts me; But, ah! ’tis quite another thing, When that same bee concludes to sting!” Dave’s book came out in 2014.

Maria was born into a wealthy family in Nantucket. Her maiden name was Talent. When she was a little girl, Maria showed an interest in the plants growing around her home on Nantucket. The women in her family - her mother, her sisters, and her aunt - all shared in the hobby of botany. It wasn't long before Maria showed an aptitude for it. She had a superior intellect, memory, and processing skills. She had a scientific mind. After marrying a Harvard-educated doctor named Varillas Owen, the young couple settled in Springfield, Massachusetts. For more than 50 years, their home became a hub for scientists and academics. Maria loved to entertain, and she drew energy from connecting with the educated people in her area. One peer said that Maria was "easily the most cultivated and best-read woman of her time in Springfield." Maria served as the President of both the Springfield Women's Club and the Springfield Botanical Society for over a decade. A renaissance woman, Maria taught botany, French, astronomy, and geography. Although Maria enjoyed teaching all of these subjects equally, she always said that for her, happiness could be found in the study of botany. In 1882, Maria contributed to a little Nantucket guidebook. Maria's part featured a listing of all the plants on the island of Nantucket. The project was a bit retrospective for Maria since she was writing about the plants of her childhood and featuring specimens she'd collected as a young woman. Even after moving to Springfield, Maria still botanized in the area whenever she came back to Nantucket. Although she spent five decades of her adult life in Springfield, she always regarded Nantucket as her home. In 1888, Maria wrote her masterpiece - a comprehensive Flora of Nantucket, which featured almost 800 species and varieties. After her book, Maria made it a point to connect with new generations of Nantucket botanists. The young botanists were eager to make her acquaintance; Maria was a one-woman repository of all the plants of Nantucket. When the botanist Bicknell published a follow-up catalog about Nantucket in the early 1900s, he continually referred to Maria's work, which explicitly documented when and where plants were introduced. For instance, when she wrote about chicory, she said it was, "a roadside plant along the south end of Orange Street" where it had thrived for "fifty years." At the age of 87, Maria was asked about one of the plants in her flora - Tillaea. The plant was hard to find, and botanists were curious about a location for it. Maria wrote, "My patch of Tillaea... doubtless still exists, and there is a happy day in store for any botanist who sees it at just the right season." Maria died in 1907. She had moved back to Nantucket to live with her daughter. Walter Deane wrote in his Rhodora biography of Maria that she died, "...on a bright morning with the room flooded with sunshine, which she always loved, and filled with iris, columbine, and cornflowers…. She lived true to the [Latin] motto of her mother's family 'Post tenebris, speramus lumen de lumine,' which [Maria] always loved to translate, 'After the darkness, we hope for light from the source of light.'"

Không phải thực vật, không phải động vật, và cũng không phải là nấm, mà là một sinh vật có cả ba đặc tính này. Đó là một sinh vật nguyên sinh có cấu tạo từ một tế bào duy nhất, có khả năng di chuyển, không có não nhưng có trí nhớ và có khả năng học hỏi đáng ngạc nhiên. Và các nhà khoa học Pháp đặt tên cho chúng là « Blob ». Giả định rằng năm khẳng định sau đây là kiến thức cơ bản của sinh học. Tế bào, đơn vị cơ bản của sự sống có kích thước bé nhỏ. Để di chuyển, một sinh vật phải có những cơ quan vận động đặc thù. Mỗi một loài sở hữu một lượng nhiễm sắc thể nhất định. Những sinh vật sống sinh sản theo giới tính được chia làm hai giống : đực và cái. Trung tâm của trí nhớ và học hỏi nằm ở não bộ. Thế nhưng, Blob là loài sinh vật đặc biệt có tên khoa học đầy đủ là Physarum polycephalum – một sự kết hợp giữa tiếng Latinh và Hy Lạp, có nghĩa là « sinh vật nhầy có nhiều đầu ». Tên này do nhà khoa học Mỹ Lewis David von Schweinitz, chuyên nghiên cứu về loài nấm, đặt cho vào năm 1882. Một tế bào - một mảng cơ thể khổng lồ Loại « nấm nhầy » này đã thu hút sự chú ý của các nhà khoa học từ nửa cuối thế kỷ trước, do những đặc tính sinh học khá kỳ lạ của chúng. Chỉ có một tế bào duy nhất, nhưng « nấm nhầy » không thuộc hệ thực vật, không hẳn là động vật, mà cũng không hoàn toàn là « nấm ». P. polycephalum có cả ba tính chất đó. Chính vì thế mà cô Audrey Dussutour, nhà nghiên cứu sinh học thuộc Trung Tâm Nghiên Cứu Khoa Học Quốc Gia CNRS ở Toulouse, sau 8 năm ròng rã tìm hiểu loại nấm nhầy lại thích gọi chúng là « Blob », lấy cảm hứng từ tên của một loại sinh vật trong một bộ phim kinh dị của Mỹ cùng tên The Blob, sản xuất năm 1958. Trong phim, đó là một sinh vật nhầy, từ trên trời rơi xuống, ăn tươi nuốt sống người và có khả năng chống cự lại được mọi ý định trừ khử nó. Nhưng Blob của cô Dussutour không hung dữ, không ăn thịt người. Vậy người ta có thể tìm Blob ở đâu ? Cô Audrey Dussutour trong một buổi thuyết trình có giải thích : « Chắc chắn là quý vị đã thấy Blob rồi, nhưng không biết đấy là Blob. Chúng thường sống ở những vùng rừng thấp. Đó chính là những mảng lớn mầu vàng bám trên các thân cây. Blob có đủ các mầu sắc : hồng, đỏ, xanh dương, nhưng thường có mầu vàng, đôi khi trắng. » Tuy chỉ có một tế bào duy nhất, nhưng Blob có thể tăng gấp đôi kích thước trong vòng 24 giờ, và có thể đạt đến kích cỡ hàng chục mét vuông, thậm chí hơn một km2. « Blob (theo quan sát của nhà nghiên cứu) có thể đạt đến một kích thước tối đa 10m². Hiện tại chúng tôi chưa tài nào làm cho nó lớn hơn được nữa, nhưng điều này rất có thể làm được. Quý vị tưởng tượng xem, giả dụ như tôi đây có diện tích 2m². Trong người tôi, có khoảng 100 tỷ tế bào, tức cứ mỗi 10 µm có một tế bào. Nhưng một Blob ở đây chỉ có một tế bào duy nhất. Quý vị nghĩ xem chỉ một tế bào duy nhất thôi mà đã chiếm đến 10m². Quả thật, nếu tôi so sánh những tế bào nhỏ xíu của tôi với tế bào của Blob, chẳng khác nào giống như so nắm đấm tay của tôi với cả địa cầu này. » Làm thế nào một sinh vật đơn bào lại có kích cỡ to đến như thế ? Bởi một lẽ rất đơn giản, tuy chỉ có một tế bào, nhưng Blob có đến hàng chục ngàn nhân tế bào, vốn dĩ được nhân lên theo cấp lũy thừa sau mỗi tám tiếng đồng hồ. Điều này giải thích vì sao người ta có thế tìm thấy ở dãy núi Appalaches, Hoa Kỳ có những mảng Blob to đến 1,3 km². Biết di chuyển, có 221 giới tính và gần như « bất tử » Vì là sinh vật đơn bào, nên Blob cũng có đầy đủ các chức năng : tai, mắt, mũi, bao tử, phổi… Đáng sợ hơn nữa là Blob có thể di chuyển, với tốc độ khoảng 1cm/giờ, nhưng khi đói chúng có thể đạt tới vận tốc 4cm/giờ. Vậy chúng di chuyển được bằng cách nào ? Cứ mỗi hai phút, dòng lưu thông mạch chất nguyên sinh (máu của Blob) đổi chiều. Ông Marc Durand, nhà vật lý ở đại học Paris – Diderot giải thích rằng : « Bằng cách co giãn các mạch máu thật mạnh theo chiều này hay chiều kia mà Blob có thể chọn hướng di chuyển cho mình ». Tức là, Blob di chuyển bằng cách tiến hai bước, lùi một bước. Quá trình sinh sản của Blob cũng khác lạ, không như những gì chúng ta đã học qua trong các bài giảng về giáo dục giới tính. Vào giai đoạn này, sinh vật xốp nhầy của chúng ta rời môi trường âm u ưa thích, vươn ra ánh sáng và biến thành hàng ngàn túi bào tử hình cầu đủ mầu sắc, và sẵn sàng giải phóng một đám bào tử. Hai bào tử khác giới tính gặp nhau sản sinh ra một Blob mới. Nhưng cô Dessurtour lưu ý : « Ở các loài cây, động vật, hay loài nấm, bao giờ cũng cần đến hai giới tính đối lập : đực và cái. Nhưng ở Blob, người ta đếm được 221 giới tính khác nhau. Nghĩa là không như chúng ta, khi các bạn bước vào một căn phòng gặp ai, bạn chỉ có 50% cơ may gặp người khác giới, nhưng Blob thì có đến 99,5% cơ hội gặp được một Blob có giới tính khác ». Vậy khi nào thì Blob chết ? Đây là điểm mà hoàng đế Tần Thủy Hoàng khi còn sống rất muốn có mà không bao giờ đạt được : Blob là sinh vật bất tử. « Có hai thứ Blob không thích : ánh sáng và bị bỏ đói. Khi Blob rơi vào tình trạng nguy hiểm này, nó sẽ làm gì ? Nó héo đi. Nó trở nên xơ cứng lại. Miếng xơ này có thể giữ nguyên như thế trong vòng nhiều năm liền. Cho nên một ngày nào đó, bạn chán nuôi blob ở phòng thí nghiệm rồi, bạn muốn đi du lịch, bạn chỉ cần phơi khô nó, rồi cất vào tủ. Hai tuần sau trở về, bạn chỉ cần nhỏ vài giọt nước là nó sống lại. » Không những bất tử mà dường như Blob còn có phép phân thân như Tôn Ngộ Không. Bạn thử cắt Blob làm đôi xem, hai phút sau, các vết cắt liền sẹo, và bạn sẽ có 2 Blob giống nhau như đúc, y như là sinh sản vô tính. Khi để hai Blob gần nhau, nếu thấy « hợp tính » thì chúng nhập lại thành một. Nhưng khi đặt hai loài Blob khác biệt cạnh nhau, sẽ có một Blob bị tiêu diệt. Không não, nhưng thông minh Blob đặc biệt gây ngạc nhiên cho các nhà khoa học ở điểm, tuy là sinh vật đơn bào nguyên sinh, nhưng Blob cũng có trí thông minh, dù rằng không hề có não. Blob có khả năng phát triển các chiến thuật cá nhân hay tập thể tùy theo mức độ khó khăn của các nhiệm vụ đặt ra cho Blob. « Chúng tôi đặt nhiều mẫu Blob con trong một mê cung. Nhiệm vụ của chúng là phải thoát ra khỏi mê cung này. Những hình ảnh ở đây cho thấy những con Blob nhỏ đã nhập lại với nhau, rồi phủ toàn bộ mê cung, một cách nhanh chóng chúng đã tìm thấy đường thoát khỏi mê cung. » Tương tự trong dinh dưỡng, Blob có khả năng chọn lựa một cách hiệu quả những nguồn thực phẩm nào có chế độ dinh dưỡng cân bằng nhất, và có lợi cho sức khỏe nhất. « Ở đây các bạn thấy những viên thực phẩm, có chứa đựng một hàm lượng đường và đạm nào đó. Và chỉ có một viên là tốt cho sức khỏe và sự sống còn của Blob. Khi chúng tôi để một Blob ở giữa những viên thực phẩm này, chúng tôi thấy là trong 100% các trường hợp, Blob đều chọn chế độ dinh dưỡng thích hợp. Nó không bao giờ bị nhầm cả. » Nếu nói đến trí thông minh, thì phải nghĩ đến trí nhớ và khả năng học hỏi. Blob của chúng ta có cả hai. Câu hỏi đặt ra làm thế nào Blob ghi nhớ khi mà không có não ? « Blob đã tìm cho mình một giải pháp : Đó là có bộ nhớ không phải bên trong mà là bên ngoài. Mỗi khi Blob dịch chuyển, nó để lại phía sau nó vệt nước nhầy. Giống như là bóng ma của Blob một giờ trước đó. Blob từng ở điểm này, nó không tìm thấy được gì cả, thể là nó thu hồi toàn bộ ‘đồ nghề’, và rồi nó đến khám phá phía khác của chiếc hộp. Chất nhầy mà Blob để lại phía sau nó giống như là một bộ nhớ. Lúc ấy, Blob hiểu rằng nó đã từng đi qua nơi này và ở đó chẳng có gì hết. Nó sẽ không bước qua vết nhầy đó nữa. » Thí nghiệm của các nhà khoa học Pháp cho thấy Blob cũng có khả năng giao tiếp, truyền đạt thông tin. Ví dụ khi tìm được nguồn thức ăn, Blob thông báo cho đồng bọn bằng cách để lại vết canxi. Là những sinh vật rất có « cá tính » Vì trên thế giới có hơn 1.000 loài Blob khác nhau nên chúng cũng có « cá tính » riêng. Blob ở Mỹ háu ăn và khám phá vùng lãnh thổ của mình bằng cách dùng những chân giả, giống như là những ngón tay dài mò mẫm trong hộp tối. Nhanh nhẹn nhất là Blob Nhật Bản, phồng to lên rồi phát triển những chân giả rộng hơn. Ngược lại, Blob Úc thì khoan thai, từ từ ngoạn cảnh trước khi phồng mình một cách hài hòa với thế giới xung quanh. Nhưng có lẽ thú vị nhất là thí nghiệm khảo sát hành vi của hai Blob khác nhau trong cùng một môi trường. Ví dụ như chuyện gì sẽ xảy ra khi để chung Blob Mỹ và Úc với nhau, hay Mỹ - Nhật chung với nhau. « Trước hết, chúng tôi để hai Blob Mỹ, hay hai Blob Nhật hoặc Úc chung với nhau. Sau đó, chúng tôi cung cấp một nguồn thức ăn. Như vậy, Blob có hai chọn lựa. Hoặc nó đi đến gặp bạn. Hoặc đi thẳng đến nguồn thức ăn. Qua quan sát, chúng tôi thấy Blob Mỹ đi thẳng một mạch đến nguồn thức ăn và hoàn toàn không quan tâm đến bạn. Blob Úc có tính cách rất đáng yêu : Mình đến gặp bạn trước đã, rồi sẽ cùng nhau đi tìm thức ăn. Hành động đầu tiên hai Blob Úc làm là nhập lại, tạo thành một Blob duy nhất. Ngược lại, Blob Nhật thì trước tiên đi đến nguồn thức ăn, nhưng sau đó cùng chia sẻ. Bây giờ chúng ta xem thử xem Blob Úc có còn dễ thương hay không khi ở chung với Blob Nhật hay Mỹ. Blob Úc cố chạy theo những con khác tìm cách để nhập thành một. Nhưng những Blob khác tránh né. Nhưng nếu bạn để một Blob Mỹ chung với một Blob Nhật, con Mỹ giết con Nhật Bản. Trên thực tế, Blob Mỹ nhập vào Blob Nhật, giết chết con Nhật, và lấy hết những gì có trong tế bào Nhật, kể cả các chất dinh dưỡng, để lại một xác Blob hoàn toàn mềm nhũn. Cứ như là nó chưa bao giờ bất tử. Cuối cùng, vì biết là Blob rất thích ăn các hạt dẹp yến mạch. Tôi thử mua loại yến mạch « sạch » (bio). Blob Úc và Nhật ăn thỏa thích, nhưng Blob Mỹ không ăn thực phẩm sạch, chỉ thích ăn những hạt dẹp yến mạch thường mua ở siêu thị lớn. » Như vậy là các bạn đã biết khá nhiều về Blob rồi đó. Có người hỏi rằng liệu Blob có nguy hiểm cho chúng ta hay không ? Liệu chúng ta có nên sợ một ngày nào đó Blob sẽ tràn ngập khắp thế giới ? Cô Audrey Dussutour trả lời là « Không ». Bởi vì, Blob đã xâm chiếm trái đất từ 500 triệu năm nay. Trên thực tế, chúng ta rất cần đến Blob, vì chúng giữ vai trò tái tạo nguồn dinh dưỡng trong thiên nhiên. Blob ăn nấm và vi khuẩn, để rồi sau đó thải ra môi trường các chất vi sinh có lợi cho cây cỏ. Một chi tiết thú vị khác được cô Dessutour tiết lộ là Blob rất thích lòng đỏ của trứng. Vậy chúng ta có thể « nuôi » Blob được không ? Xin thưa là được. Nhưng cô Dussutour lưu ý đây là một loài sinh vật bò sát. Chính vì đặc tính này, mà cô Dussutour còn ví Blob như là ORNI (Objet Rampant Non Identifié – Vật thể bò sát không xác định), lấy cảm hứng từ OVNI (Objet Volant Non Identifié - Vật thể bay không xác định).
