Many of our electronics today rely on batteries, from laptops to phones to smart home appliances to even cars. It’s almost ironic, then, that these critical batteries are also one of the most dangerous things we keep near our bodies, not to mention a hazard to the health of the planet as well. From the way they are made to the unsustainable metals and chemicals they contain, batteries, by nature, seem opposed to life itself.

Green energy like solar and wind can go only as far as recharging batteries, but we still need these volatile objects to power devices directly. This innovative battery, however, attempts to reinvent batteries from the ground up to provide true sustainable power to the point that they can even be broken down as compost. Even more intriguing, they’re made of materials you’d least expect to find in batteries: paper and water.

Technically speaking, the batteries aren’t made of the same kind of paper you write on or read from. It actually uses cellulose as the structural backbone and separator of the battery, an abundant material derived from plants and also used in paper, hence the name. As for water, it’s used as the foundation for the electrolytes that actually carry the electrical flow between the zinc-based anode and the manganese-based cathode, both of which are non-reactive, safe, and commonly found everywhere.

This unusual composition for a battery yields many benefits beyond simply being made of sustainable materials. For one, the battery has unbelievable resilience and can still output power even when cut in half, let alone not explode in your pocket when punctured. It’s also impervious to fire since it uses water-based electrolytes. This practically removes the need for those fancy but complicated and expensive cooling systems in phones and laptops, presuming they get used in those devices. The batteries can also be folded and bent safely, finally realizing the dream of flexible batteries.

The Flint Paper Batteries are advertised to have the same performance in terms of output and longevity as typical toxic rechargeable batteries. And yes, they’re rechargeable as well. They won’t live forever, though, and when they’ve finally lost their charge for good, simply removing the vacuum-sealed casing starts the natural degradation process that breaks them down into harmless components.

It all sounds idyllic but the technology is not completely ready for mass consumption just yet. One of the biggest hurdles that still needs to be overcome is mass production, and Flint’s creators are planning on using currently existing lithium-ion battery manufacturing processes in order to minimize production and adoption costs. When that happens, we could finally take a major step forward in running not only on green power but also on safe and recyclable batteries as well.

We’ve seen many striking lamp designs inspired by beautiful things in the world. Most of them get their cues from nature, taking inspiration from the moon, trees, or even mushrooms. While that in itself is a form of art, it takes more creativity and skill to turn something uninspiring or unsettling into a stunning and elegant design. This desk lamp, for example, looks soothing and calming in the dark, and you’ll probably never guess that it was made by repurposing an existing object that is associated not with beauty or elegance but with blood, pain, and wounds.

You might not be familiar with its name, but the pus tray is a common sight in hospitals, operating rooms, and TV shows depicting such scenes. Often made of stainless steel or even plastic, the kidney-shaped vessel is often used to collect pus but is sometimes depicted to hold bloody cotton, surgical tools, bullets, and other things that might come out from a body during surgery. Even the name alone carries a very negative connotation, and one can hardly imagine such a medical device being used for something less disturbing.

POND, however, proves that presumption wrong. It is part of a project that attempts to give new meaning to existing products, transforming them for a completely different and almost opposite purpose. In this particular case, a white-coated tray serves as the base for a cylindrical lighting element that’s placed not in the middle but near the edge of the tray. In daytime or in bright light, the lamp already looks interesting because of its unique shape, but the real magic happens when it becomes the only light source in a dark room.

The bowl virtually becomes a literal pond of light, using the natural contours of the tray to create an enchanting play of light and shadow. Unlike other lamps, the outward-facing surface of the pus tray is completely devoid of illumination, creating an effect not unlike the dark side of the moon. The curves and gently diffused light work together to create a soothing effect, the complete opposite of the proper medical use of the pus tray.

Given its bowl shape, POND can also be used as a container of sorts for small items. Of course, those objects will interfere and interact with the light, but that, in turn, could create an even more interesting visual, like fish swimming in a mystical pond of light.

Des chercheurs de l’Université du Michigan ont mis au point une technique absolument dingue qui permet de générer des spectrogrammes ayant l’allure d’images capables de produire des sons qui leur correspondent lorsqu’ils sont écoutés. Ils appellent cela des « images qui sonnent ».

Leur approche est simple et fonctionne sans entraînement spécifique. Elle s’appuie sur des modèles de diffusion text-to-image et text-to-spectrogram pré-entraînés, opérant dans un espace latent partagé. Durant le processus de génération, les deux modèles « débruitent » des latents partagés de manière simultanée, guidés par deux textes décrivant l’image et le son désirés.

Le résultat est bluffant ! Ça donne des spectrogrammes qui, vus comme des images, ressemblent à un château avec des tours, et écoutés comme des sons, font entendre des cloches. Ou des tigres dont les rayures cachent les motifs sonores de leurs rugissements.

Pour évaluer leur bidouille, les chercheurs ont utilisé des métriques quantitatives comme CLIP et CLAP, ainsi que des études de perception humaine. Leur méthode dépasse les approches alternatives et génère des échantillons qui collent finement aux prompts textuels dans les deux modalités. Ils montrent aussi que coloriser les spectrogrammes donne des images plus agréables à l’œil, tout en préservant l’audio.

Cette prouesse révèle qu’il existe une intersection entre la distribution des images et celle des spectrogrammes audio et en dépit de leurs différences, ils partagent des caractéristiques bas niveau comme les contours, les courbes et les coins. Cela permet de composer de façon inattendue des éléments visuels ET acoustiques, comme une ligne qui marque à la fois l’attaque d’un son de cloche et le contour d’un clocher.

Les auteurs y voient une avancée pour la génération multimodale par composition et une nouvelle forme d’expression artistique audio-visuelle. Une sorte de stéganographie qui cacherait des images dans une piste son, dévoilées uniquement lorsqu’elles sont transformées en spectrogramme.

Pour recréer cette méthode chez vous, il « suffit » d’aller sur le Github du projet et de suivre les instructions techniques.
