  1. Jets From Impact

    When a test tube of liquid hits a surface, the curvature of the meniscus focuses the rebounding fluid into a jet. In this video, researchers show some of the many variations they’ve explored on these experiments–from changing the depth of the fluid and the shape of the container, to changing the working fluid to honey or to dry grains. It’s a nice introduction to a fascinating phenomenon! (Video and image credit: H. Watanabe et al.; research credit: H. Watanabe et al. and K. Kobayashi et al.)

  3. Inside an Ear

    Our ears, like those of many other animals, convert mechanical signals to electrical ones, through a Rube-Goldberg-esque series of transformations. External sound waves make their way down the soft tube of the ear canal, which funnels them to a thin-walled cone, the eardrum, that’s about half as large as a dime. Here, the vibrating air pushes against the cone’s membrane, and those vibrations travel onward through a linked trio of small bones that amplify the vibration’s amplitude.

    The last of these bones presses against an even smaller, oval-shaped membrane. As the bone moves, it shakes the membrane, sending waves through the liquid on its other side. Those waves travel down the spirals of the tiny, pea-sized cochlea, named for a snail shell’s shape. As the waves move through the liquid, they bend bundles of hair-like strands back and forth, like tall grass waving in a breeze. The bending triggers a chemical that binds to nerves at the base of the bundles, sending an electrical signal through the nerve and into the brain.

    But the hair-like bundles, known as stereocilia, are also able to amplify incoming vibrations. In this case, the bundles in the outer portion of the cochlea expend energy to bend more than the incoming vibrations naturally make them move. This bending amplifies the fluid motion that gets transmitted to stereocilia further down the line; it’s those bundles that will make the final conversion to an electrical signal the brain receives.

  4. Bouncing on a Wave

    On a vibrating fluid, droplets can bounce and interact in complex ways. Here, researchers demonstrate some of the peculiar dynamics of these wave-guided droplets, showing how they can do things like pair up in waltzes. To keep the droplets from coalescing with one another, they perform their experiments in a pressurized chamber; the higher air pressure makes it harder for the air film between droplets to drain during a collision, making the droplets unable to coalesce. Under these conditions, the authors show that the droplet-wave system has quantum-like statistics. (Video and image credit: J. Clampett et al.)

  9. Scrubbing Bubbles

    Cleaning produce helps fruits and vegetables last longer and reduces the chances for foodborne illness. But it can be a difficult feat with soft, delicate foods like tomatoes, berries, or greens. Current methods often combine ultrasonic cleaning and chemicals like chlorine. Instead, researchers are looking to boost the cleaning power of bubbles themselves by giving them an acoustic pick-me-up.

    Stop-and-go. A bubble slides along an inclined surface in a pronounced stop-and-go motion when vibrated near its frequency for translational resonance.

    The team combined a bubble-filled bath with sound at low (sub-cavitation) frequencies. They found that driving sound waves at the right frequency could vibrate the bubbles in a way that made them slide in a stop-and-go motion along inclined surfaces. This swaying significantly boosted their cleaning power; getting surfaces 90% cleaner than non-resonating bubbles did. (Image credit: S. Hok/Cornell University; video and research credit: Y. Lin et al.; via Gizmodo)

    Les clés secrètes pour apaiser votre mental et retrouver l’harmonie

    par Khalid Akayousse4 mai 2026

    Il y a quelque chose d’étrange dans notre manière de vivre.

    On appelle un cadeau un présent.
    Et on appelle aussi présent l’instant qui est là.

    Et pourtant…
    combien de présents laissons-nous encore emballés ?

    TU N’ES PAS EN RETARD. TU ES ABSENT.

    Tu crois manquer de temps.
    Mais ce n’est pas le temps qui manque.

    C’est ta présence.

    Ton corps traverse les jours.
    Ton esprit habite ailleurs.
    Hier te poursuit.
    Demain t’aspire.

    Et pendant que tu négocies avec ce qui n’existe plus
    ou avec ce qui n’existe pas encore…

    la vie, elle, attend.

    Elle attend que tu arrives.

    LE PLUS GRAND CADEAU N’A PAS DE PRIX

    Un enfant ne se souvient pas du jouet exact.
    Il se souvient du regard.

    Un couple ne s’effondre pas à cause d’un manque d’objets.
    Il s’effondre à cause d’un manque d’attention.

    On offre des choses pour compenser.
    On achète pour se rassurer.
    On donne pour éviter d’être là.

    Mais la vérité est brutale :

    Ce que les êtres humains veulent vraiment,
    c’est être vus.

    Être entendus.
    Être ressentis.

    Et ça…
    ça ne s’emballe pas dans du papier.

    TU PASSES À CÔTÉ

    Chaque respiration est un présent.
    Chaque battement de ton cœur est un présent.
    Chaque personne que tu croises pourrait être la dernière fois.

    Oui.
    La dernière.

    Ce mot te dérange ?

    Il devrait.

    Parce que c’est la réalité silencieuse que l’on évite.
    On vit comme si tout allait durer.
    Comme si on aurait toujours le temps de dire “je t’aime”.
    Toujours le temps de pardonner.
    Toujours le temps de commencer à vivre vraiment.

    Mais personne ne t’a promis demain.

    LE VRAI DRAME

    Le vrai drame, ce n’est pas de mourir.
    C’est de ne pas avoir été là avant.

    De s’apercevoir trop tard qu’on a vécu en mode automatique.
    Qu’on a survécu au lieu de ressentir.
    Qu’on a rempli des journées sans jamais habiter une seule minute.

    Tu sais ce qui fait dresser le poil ?

    Ce moment où tu réalises que tu étais là…
    mais pas présent.

    Que tu as serré des mains sans connexion.
    Écouté sans entendre.
    Aimé sans oser.

    Et que le temps, lui, n’a pas attendu que tu te réveilles.

    LE CADEAU EST DÉJÀ DANS TES MAINS

    Le présent ne se cherche pas.
    Il est déjà là.

    Il est dans cette respiration que tu viens de prendre.
    Dans la lumière qui touche ton visage.
    Dans la vibration de ton cœur qui insiste encore.

    La vie ne te doit rien.
    Mais elle t’offre tout, maintenant.

    Chaque instant est un paquet ouvert devant toi.
    Et tu as le choix :

    Le regarder distraitement.
    Ou le déballer avec conscience.

    ET SI TU OSAIS ?

    Oser ralentir.
    Oser sentir.
    Oser être vulnérable.

    Oser dire ce que tu repousses.
    Oser écouter vraiment.
    Oser aimer sans garantie.

    Parce que c’est ça, être présent.

    C’est accepter que tout soit fragile.
    Et aimer quand même.

    Peut-être que le mot “présent” n’est pas un hasard.

    Peut-être que la langue nous murmure ce que nous refusons d’entendre :

    La vie est un cadeau.
    Mais un cadeau non ouvert devient un regret.

    Alors dis-moi…

    Aujourd’hui,
    vas-tu encore laisser le tien fermé ?

  16. Bouncing Indefinitely

    On the surface of a gently vibrating liquid, a droplet can bounce indefinitely without coalescing, kept aloft by an air film too small to see. As long as the droplet lifts off before the air layer drains out from under it, the droplet won’t contact the water below. Now scientists have shown that this is possible with a solid surface, too.

    Using an atomically smooth mica plate, researchers were able to bounce a droplet indefinitely without wetting the surface. At higher vibration rates (below), the droplet essentially hovers in place, bouncing so quickly that we simply see its shape vibrating in response to the surface. (Image and research credit: L. Molefe et al.; via APS)

  21. Wavy Water Entry

    When an object like a sphere enters the water, it drags air into the water behind it, creating a cavity. Depending on the sphere’s impact speed, the cavity might close first under the water, forming a deep seal, or at the surface with a surface seal. But, as this video points out, water often isn’t still. Here, they explore how the sphere’s entry changes when there are ripples on the water surface. (Video and image credit: M. Ibrahim et al.; via GFM)
