Cilia Back

Scoliosis is a human condition where the spine develops a curve yet its cause is still a little mysterious. Here, researchers turn to a simpler but similar organism, the zebrafish, for clues. Assembled in 3D from micro-computed tomography images, we see the healthy spine of a young zebrafish (grey) and curved spines of three different fish (highlighted in bright colours) laid over the top. These fish have a genetic mutation – but how might this lead to scoliosis? The key could be cilia – hairlike structures on the surface of cells. Their mutation changes the cilia so they can’t transfer important chemicals, or waft cerebrospinal fluid around as efficiently as they do in healthy fish. Researchers believe this leads to a build up of astroglia cells, preventing the spine from shaping properly. As the developing human nervous system also relies on cilia, these important clues might influence future therapies.

James Webb space telescope offers best glimpse ever into the icy planetesimals of the early solar system

New studies of trans-Neptunian objects reveal how their colors and surface reflectance today are linked to their formation locations in the early solar system and more.

New studies led by researchers at the University of Central Florida offer for the first time a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs.

The findings, published today in Nature Astronomy, reveal the distribution of ices in the early solar system and how TNOs evolve when they travel inward into the region of the giant planets between Jupiter and Saturn, becoming centaurs.

TNOs are small bodies, or ‘planetesimals,’ orbiting the sun beyond Pluto. They never accreted into planets, and serve as pristine time capsules, preserving crucial evidence of the molecular processes and planetary migrations that shaped the solar system billions of years ago. These solar system objects are like icy asteroids and have orbits comparable to or larger than Neptune’s orbit.

Prior to the new UCF-led study, TNOs were known to be a diverse population based on their orbital properties and surface colors, but the molecular composition of these objects remained poorly understood. For decades, this lack of detailed knowledge hindered interpretation of their color and dynamical diversity. Now, the new results unlock the long-standing question of the interpretation of color diversity by providing compositional information.

“With this new research, a more-complete picture of the diversity is presented and the pieces of the puzzle are starting to come together,” says Noemí Pinilla-Alonso, the study’s lead author.

“For the very first time, we have identified the specific molecules responsible for the remarkable diversity of spectra, colors and albedo observed in trans-Neptunian objects,” Pinilla-Alonso says. “These molecules — like water ice, carbon dioxide, methanol and complex organics — give us a direct connection between the spectral features of TNOs and their chemical compositions.”

Using the James Webb Space Telescope (JWST), the researchers found that TNOs can be categorized into three distinct compositional groups, shaped by ice retention lines that existed in the era when the solar system formed billions of years ago.

These lines are identified as regions where temperatures were cold enough for specific ices to form and survive within the protoplanetary disk. These regions, defined by their distance from the sun, mark key points in the early solar system's temperature gradient and offer a direct link between the formation conditions of planetesimals and their present-day compositions.

Rosario Brunetto, the paper’s second author and a Centre National de la Recherche Scientifique researcher at the Institute d'Astrophysique Spatiale (Université Paris-Saclay), says the results are the first clear connection between formation of planetesimals in the protoplanetary disk and their later evolution. The work sheds light on how today’s observed spectral and dynamical distributions emerged in a planetary system that’s shaped by complex dynamical evolution, he says.

“The compositional groups of TNOs are not evenly distributed among objects with similar orbits,” Brunetto says. “For instance, cold classicals, which formed in the outermost regions of the protoplanetary disk, belong exclusively to a class dominated by methanol and complex organics. In contrast, TNOs on orbits linked to the Oort cloud, which originated closer to the giant planets, are all part of the spectral group characterized by water ice and silicates.”

Brittany Harvison, a UCF physics doctoral student who worked on the project while studying under Pinilla-Alonso, says the three groups defined by their surface compositions exhibit qualities hinting at the protoplanetary disk's compositional structure.

“This supports our understanding of the available material that helped form outer solar system bodies such as the gas giants and their moons or Pluto and the other inhabitants of the trans-Neptunian region,” she says.

In a complementary study of centaurs published in the same volume of Nature Astronomy, the researchers found unique spectral signatures, different from TNOs, that reveal the presence of dusty regolith mantles on their surfaces.

This finding about centaurs, which are TNOs that have shifted their orbits into the region of the giant planets after a close gravitational encounter with Neptune, helps illuminate how TNOs become centaurs as they warm up when getting closer to the sun and sometimes develop comet-like tails.

Their work revealed that all observed centaur surfaces showed special characteristics when compared with the surfaces of TNOs, suggesting modifications occurred as a consequence of their journey into the inner solar system.

Among the three classes of TNO surface types, two — Bowl and Cliff — were observed in the centaur population, both of which are poor in volatile ices, Pinilla-Alonso says.

However, in centaurs, these surfaces show a distinguishing feature: they are covered by a layer of dusty regolith intermixed with the ice, she says.

“Intriguingly, we identify a new surface class, nonexistent among TNOs, resembling ice poor surfaces in the inner solar system, cometary nuclei and active asteroids,” she says.

Javier Licandro, senior researcher at the Instituto de Astrofisica de Canarias (IAC, Tenerife, Spain) and lead author of the centaur’s work says the spectral diversity observed in centaurs is broader than expected, suggesting that existing models of their thermal and chemical evolution may need refinement.

For instance, the variety of organic signatures and the degree of irradiation effects observed were not fully anticipated, Licandro says.

“The diversity detected in the centaurs populations in terms of water, dust, and complex organics suggests varied origins in the TNO population and different evolutionary stages, highlighting that centaurs are not a homogenous group but rather dynamic and transitional objects” Licandro says. “The effects of thermal evolution observed in the surface composition of centaurs are key to establishing the relationship between TNOs and other small bodies populations, such as the irregular satellites of the giant planets and their Trojan asteroids.”

Study co-author Charles Schambeau, a planetary scientist with UCF’s Florida Space Institute (FSI) who specializes in studying centaurs and comets, emphasized the importance of the observations and that some centaurs can be classified into the same categories as the DiSCo-observed TNOs.

“This is pretty profound because when a TNO transitions into a centaur, it experiences a warmer environment where surface ices and materials are changed,” Schambeau says. “Apparently, though, in some cases the surface changes are minimal, allowing individual centaurs to be linked to their parent TNO population. The TNO versus centaur spectral types are different, but similar enough to be linked."

How the Research Was Performed

The studies are part of the Discovering the Surface Composition of the trans-Neptunian Objects, (DiSCo) project, led by Pinilla-Alonso, to uncover the molecular composition of TNOs. Pinilla-Alonso is now a distinguished professor with the Institute of Space Science and Technology in Asturias at the Universidad de Oviedo and performed the work as a planetary scientist with FSI.

For the studies, the researchers used the JWST, launched almost three years ago, that provided unprecedented views of the molecular diversity of the surfaces of the TNOs and centaurs through near-infrared observations, overcoming the limitations of terrestrial observations and other available instruments.

For the TNOs study, the researchers measured the spectra of 54 TNOs using the JWST, capturing detailed light patterns of these objects. By analyzing these high-sensitivity spectra, the researchers could identify specific molecules on their surface. Using clustering techniques, the TNOs were categorized into three distinct groups based on their surface compositions. The groups were nicknamed "Bowl," "Double-dip" and "Cliff" due to the shapes of their light absorption patterns.

They found that:

Bowl-type TNOs made up 25% of the sample and were characterized by strong water ice absorptions and a dusty surface. They showed clear signs of crystalline water ice and had low reflectivity, indicating the presence of dark, refractory materials.

Double-dip TNOs accounted for 43% of the sample and showed strong carbon dioxide (CO2) bands and some signs of complex organics.

Cliff-type TNOs made up 32% of the sample and had strong signs of complex organics, methanol, and nitrogen-bearing molecules, and were the reddest in color.

For the centaurs study, the researchers observed and analyzed the reflectance spectra of five centaurs (52872 Okyrhoe, 3253226 Thereus, 136204, 250112 and 310071). This allowed them to identify the surface compositions of the centaurs, revealing considerable diversity among the observed sample.

They found that Thereus and 2003 WL7 belong to the Bowl-type, while 2002 KY14 belongs to the Cliff-type. The remaining two centaurs, Okyrhoe and 2010 KR59, did not fit into any existing spectral classes and were categorized as "Shallow-type" due to their unique spectra. This newly defined group is characterized by a high concentration of primitive, comet-like dust and little to no volatile ices.

Previous Research and Next Steps

Pinilla-Alonso says that previous DiSCo research revealed the presence of carbon oxides widespread on the surfaces of TNOs, which was a significant discovery.

“Now, we build on that finding by offering a more comprehensive understanding of TNO surfaces” she says. “One of the big realizations is that water ice, previously thought to be the most abundant surface ice, is not as prevalent as we once assumed. Instead, carbon dioxide (CO₂) — a gas at Earth’s temperature — and other carbon oxides, such as the super volatile carbon monoxide (CO), are found in a larger number of bodies.”

The new study’s findings are only the beginning, Harvison says.

“Now that we have general information about the identified compositional groups, we have much more to explore and discover,” she says. “As a community, we can start exploring the specifics of what produced the groups as we see them today.”

D'ailleurs, la question du futur semble être au coeur des préoccupations de tout le monde en ce moment à la maison. C'est à un point ou même Papa s'en mêle. C'est rare de le voir s'investir dans autre chose que son travail. Nous avons aussi appris il y a peu que mon oncle Adelphe serait grand-père sous peu, et Maman dit que cela travaille beaucoup Papa, même si je ne suis pas bien sure de comprendre pourquoi. Mais il faut dire que des choses qui nous paraitraient anodines ont tendance à beaucoup travailler Papa. Tout ce qui touche à Adelphe en fait. D'ailleurs, je l'appelle mon oncle, mais c'est le cousin de mon père, c'est juste qu'ils sont si proches que personne ne fait la distinction pour eux. J'ai l'impression d'avoir répété cette phrase ma vie entière.

Cléo et Antoine vont aller à l'université, et Sélène va aller à Paris pour prendre des cours de tennis avec un champion. C'est son ambition, de vivre du sport et de gagner des tournois. J'aimerai bien un jour vous montrer une coupure de journal qui parle de ma soeur. J'imagine qu'elle finira par épouser son Berto. Ce serait incroyable qu'ils forment un couple de champions de tennis.

Transcription :

Constantin « Dis-moi Sélène, tu ne comptes toujours pas candidater dans une université ? »

Sélène « Non Papa, toujours pas. »

Constantin « Je n’ai pas vraiment saisi ta raison. Je pense que ce serait bien pour toi. »

Sélène « Je ne pense pas que ce serait très utile. Je veux jouer au tennis. Comme joueuse professionnelle je veux dire. »

Constantin « Mais enfin Sélène, courir après une balle, cela ne peut quand même pas remplir une vie. »

Sélène « Mais enfin Papa, creuser dans le sable, cela ne peut quand même pas remplir une vie. »

Constantin « Quoi ? De quoi tu… ? Oh ! Je vois… Enfin je crois. Je pense, ma fille, que nous allons devoir nous accorder sur le fait que nous ne comprenons pas nos intérêts de vie respectifs et qu’il faudra nous efforcer de nous montrer plus ouverts. »

Sélène « Je le pense aussi. Merci Papa. »

Constantin « Mais est-ce que ton Gilberto gagne bien sa vie au moins ? Car si vous vous mariez, je tiens malgré tout à ce que tu conserves une certaine indépendance financière. »

Sélène « Oh non Papa ! Cessez de parler de mariage ! Grand-Mère suffit amplement. »

En revanche, j’ai dévoré Le rêve du jaguar du fringant Miguel Bonnefoy. Il est jeune et a déjà écrit plein de trucs, mais c’est maintenant que je le découvre, et je me suis régalée avec sa fresque historique et fantaisiste. Un portrait du Vénézuéla au XXe siècle à travers une famille (apparemment fortement inspirée de sa propre famille) qui est complètement incroyable. Antonio, le bébé abandonné trouvé sur les marches d’une église et recueilli par une muette qui vit dans les bidonvilles de Maracabio deviendra médecin et fondateur d’une université de médecine du Vénézuéla… entre temps, il connaîtra de multiples aventures (celles de son enfance sont particulièrement géniales) ; pauvre, il devra s’endurcir et devenir malin… un côté Oliver Twist dans cette partition, faire divers métiers, dont celui d’homme à tout faire dans un bordel avant d’accéder à d’autres sphères et d’autres horizons…. Laure Adler compare l’auteur à Victor Hugo ! Il y a de ça en effet dans la virtuosité de passer d’un milieu à l’autre, dans la peinture crue et émouvante des gens miséreux… un Victor Hugo juvénile d’Amérique du Sud, comme on se l’imagine, colorée et tapageuse, aux prises avec une histoire mouvementée et violente. (Encore que l’auteur soit Franco-vénézuélien, son livre fait d’ailleurs le grand écart entre les deux continents, et fantasme Paris.)

Mais malgré la violence des faits, la plume de Miguel Bonnefoy est légère, il virevolte et nous embarque dans les moments tragiques et les plus doux avec cadence et rythme, sans s’appesantir. Il a cette grâce et cette fantaisie, qui surprend sans cesse. Il mêle récits imaginaires, contes, légendes, mythologies locales et histoire avec malice.

C’est un vrai moment joyeux de lecture.

a filha mais nova de um jovem casal, cheios de paz&amor e irresponsabilidade. a avó materna praticamente tomou vivianne para si, já que os dois eram adeptos de uma linha de criação duvidosa: os irmãos mais velhos praticamente se criaram sozinhos, e pareciam ser mais colegas de quarto dos pais do que propriamente filhos. a avó não conseguia nem pensar em deixar sua única netinha com aqueles doidos. até hoje a mulher ainda guarda rancor dos progenitores por terem sido tão negligentes com ela e os irmãos.

vivienne dormia na casa dos pais, mas passava o dia com a avó e era sua fiel companhia para todos os lados: missa, reunião das vizinhas, reza do terço, sessões de costura e limpeza da casa. a sua fé e a habilidades manuais foram heranças diretas da avó. entrou no curso de letras na université de l'orangerie com uma bolsa de estudos e perdera a sua companheira alguns meses depois, integrar-se na kappa phi foi a melhor forma que encontrou de lidar com o luto. embora revirasse os olhos quando julgava as brincadeiras dos colegas, fora ali que seu espírito carente encontrara abrigo.

apesar de já ser chamada de santinha pelos colegas, a verdadeira conversão de vivienne só aconteceu após o fatídico acidente em 2015. depois de toda a confusão, acabou afastando-se mais dos amigos. vê-los constantemente fazia a mulher se recordar do pecado que cometera e até hoje não conseguia confessar em voz alta.

estudou literatura americana com muito afinco para virar youtuber e dona de casa, depois de casar-se com william, o médico americano do grupo de oração. ela queria mesmo era ter saído de Des Moines, mas seu esposo fora aceito em uma boa vaga no hospital universitário. por sentir-se muito solitária em casa, começou a registrar vídeos da rotina e dos cuidados com o lar em um canal chamado la vie de vivi, alcançando um número considerável de seguidores.

ficou tão boa na edição que os inscritos nem perceberam seus olhos inchados e a frieza do marido. vivienne imaginava que seria uma mãe jovial, com uma casa alegre e cheia de crianças. mas depois de duas perdas gestacionais, a esperança foi diminuindo e o seu companheiro ficava mais distante. a mulher compensava suas frustrações com os vídeos, atividades manuais e suas reuniões no núcleo feminino da igreja (aliás, ela ocupa o importante cargo de aconselhadora e é responsável pelo núcleo de São Miguel, o das jovens solteiras).

o casamento, cada vez mais tíbio, quase chegara ao fim quando a irmã de william deixou o sobrinho na casa dos richmond por algumas semanas. eles precisavam fazer uma viagem de negócios à paris e vivienne era muito boa com crianças. ela cuidou do garotinho com muito, muito amor! mas tanto amor que não queria devolvê-lo aos seus pais. seu marido ficara genuinamente assustado com os gritos e as lágrimas copiosas da mulher, ela implorava para que não deixassem levar o filhinho dela embora.

depois dessa crise, vivienne se comprometera a não faltar mais nas sessões online de terapia e william a diminuir os plantões. seria um ótimo início de um final feliz, se não fosse pela chegada da maldita carta.

“La tristeza no vuelve inteligente. En la tristeza estamos perdidos. Por eso los poderes tienen necesidad de que los sujetos sean tristes”

Gilles Deleuze

Gilles Deleuze fue un filósofo francés nacido en París en enero de 1925. Es considerado uno de los más importantes e influyentes del siglo XX.

Primeros años

Nació en el seno de una familia burguesa, su padre era ingeniero y su madre se ocupaba de la casa y de sus hijos, Gilles fue el segundo hijo de la familia.

En 1940 durante la Segunda Guerra Mundial, sus padres decidieron dejar a Gilles en un internado en Deauville, y es ahi, en donde el hasta entonces un estudiante mediocre, descubre la literatura y guiado por sus maestros descubre la obra de André Gide, Charles Baudelaire y Anatole France. Con la firma del armisticio, Gilles regresa a París en donde concluye sus estudios secundarios.

Durante los años de la ocupación estuvo muy marcado por la lectura de Jean Paul Sartre, particularmente por su obra “El ser y la nada” y posteriormente, esa admiración terminaría en decepción con motivo de su conferencia “El existencialismo es un humanismo”, años después.

Labor docente

Después de la guerra se incorporó a clases preparatorias literarias, y en el Lycée Henri IV siguió las lecciones de Jean Beaufret, quien fuera a su vez el “introductor” de Martin Heidegger en Francia. A pesar de sus habilidades excepcionales, no logró pasar el examen de admisión de la escuela Normal Superior de París, pero gracias a sus excelentes resultados obtuvo una beca en la Sorbonne Université.

En 1948, fue admitido como profesor y pasó un año en Alemania en la Universidad de Tubingen y a su regreso a París, impartió clases en diferentes colegios hasta 1957.

En 1964 fue nombrado profesor de la Facultad de Letras de la Universidad de Lyon en donde impartió cursos de Moral, Sociología y Filosofía General.

Obra

A pesar de ser percibido como un historiador de Filosofía, por sus trabajos sobre filósofos tan diversos como David Hume, Friedrich Nietzsche, Emmanuel Kant, Baruch Spinoza o Henri Bergson, Deleuze fue evolucionando hacia una nueva definición del filósofo como el “creador de conceptos” en la sociedad, así como creador de nuevas palabras en filosofía, con diferentes significados.

Su tesis filosófica, se centra en el concepto de “diferencia” y “repetición”, es decir de la relación de lo mismo con lo semejante, de la copia con el doble, y del efecto de la repetición con el infinito en comparación con un original. Deleuze intenta desarrollar una metafísica, de acuerdo con la física y las matemáticas de su tiempo, en la que los conceptos de multiplicidad, suceso y virtualidad remplazan respectivamente los de sustancia, esencia y posibilidad.

Al final, enfoca su interés en las relaciones entre significado, sinsentido y acontecimiento, tomando como referencia el trabajo de Lewis Carroll, y el del filósofo Whitehead y el estoicismo griego, así como una metafísica y una filosofía del arte, interesándose tanto por el cine, como por el pintor Francias Bacon.

Entre sus libros mas famosos se encuentran las monografías sobre David Hume (Empirismo y subjetividad), La filosofía critica de Kant, El Bergsonismo, sus trabajos sobre Proust, Spinoza y Focault entre muchos otros, recibiendo en 1994 el Gran Premio de Filosofía de la Academia Francesa por su basta obra.

En noviembre de 1995 Giles Deleuze muere en Paris a la edad de 70 años.

57% des juifs veulent quitter l’Europe.

Pause sourire.

Voilà une excellente nouvelle.

LPH info :

Lors du sommet du mouvement de lutte contre l’antisémitisme et de l’organisation ELNET à Vienne, des parlementaires et des représentants de villes de toute l’Europe ont discuté des moyens de lutter contre la vague d’antisémitisme. David Hirsch, professeur de sociologie au Goldsmiths College de l’Université de Londres et fondateur du mouvement Engage qui œuvre contre les boycotts académiques d’Israël, faisait partie des participants. Sur Ynet, il explique: »La plupart des antisémites que je connais pensent qu’ils ne le sont pas. Ils organisent des conférences et, selon eux, ils protègent les droits de l’homme et pensent qu’ils sont en fait les plus grands opposants à l’antisémitisme ». Le sommet qui s’est tenu à Vienne s’est concentré sur les moyens d’agir face à la vague d’antisémitisme en Europe la plus importante depuis la seconde guerre mondiale. Depuis le 7 octobre 2023, les actes antisémites ont augmenté de 400% dans certains endroits en Europe. « Nous sommes en train de perdre le combat », estime le Dr Ariel Musicant, président du congrès juif européen, « 57% des Juifs européens songent à partir. Dans quelques années, 50% des communautés n’existeront plus ». L’importance de l’événement réside dans le public cible. La plupart des participants au sommet sont des parlementaires et des représentants de villes de toute l’Europe, qui ne sont pas juifs mais sont déterminés à agir contre ce phénomène de plus en plus effrayant. Ils sont venus à la conférence pour raconter ce qu’ils font et pour entendre de nouvelles idées sur la façon d’agir. Parmi les villes représentées : Cracovie, Ljubljana, Berlin, Vienne et Malmö. Au-delà des questions abordées en présence de l’ensemble du public, des discussions ont également eu lieu en petits groupes sur les questions de lutte contre l’antisémitisme et de boycott sur Internet, dans les universités et dans le sport. Yaël Arad, présidente du Comité olympique israélien, qui a réussi à résoudre ce problème douloureux aux Jeux olympiques de Paris cet été, a participé à cette discussion.
