‘While Bats Can Only Sense The Outer Shapes And Textures Of Their Targets, Dolphins Can Peer Inside

‘While bats can only sense the outer shapes and textures of their targets, dolphins can peer inside theirs. If a dolphin echolocates on you, it will perceive your lungs and your skeleton. It can likely sense shrapnel in war veterans and fetuses in pregnant women. It can pick out the air-filled swim bladders that allow fish, their main prey, to control their buoyancy.

It can almost certainly tell different species apart based on the shape of those air bladders. And it can tell if a fish has something weird inside it, like a metal hook. In Hawaii, false killer whales often pluck tuna off fishing lines, and “they’ll know where the hook is inside that fish,” Aude Pacini, who studies these animals, tells me. “They can ‘see’ things that you and I would never consider unless we had an X-ray machine or an MRI scanner.”

This penetrating perception is so unusual that scientists have barely begun to consider its implications. The beaked whales, for example, are odontocetes that look dolphin-esque on the outside—but on the inside, their skulls bear a strange assortment of crests, ridges, and bumps, many of which are only found in males.

Pavel Gol’din has suggested that these structures might be the equivalent of deer antlers—showy ornaments that are used to attract mates. Such ornaments would normally protrude from the body in a visible and conspicuous way, but that’s unnecessary for animals that are living medical scanners.’

For any relocated TikTok users

you can say sex and kill its fine

If you don't have a profile picture people will assume you're a bot

theres barely an algorithm, if you want to see cool shit reblog things instead of just liking them

follower count doesnt matter

tumblr fame gets you one thing and it is Yelled At

no one knows what the fuck the nsfw policy is

block anyone that annoys you even a little bit

And most importantly:

post cringe

I highly recommend trying out mending your own clothes when they have holes or tears. Even if you’re totally new to sewing and mending and not skilled at it yet, it genuinely changes how you feel about your clothes. Just trying to darn a small hole in an old tshirt, or trying your best to tidily sew it shut will make it go from being just a shirt you own, to being something you’re maybe a bit proud of. If you do visible mending, it’ll also make whatever you fix up into something unique. It’s a nice feeling.

Note to self: Let the system complicate itself. Increasing complexity is healthy. Initial complexity is a collapse risk.

This applies to everything – gardening, gaming groups, even religion. If you try to do everything you want to do at once, you will fail – the harvest will be lackluster; the game will fall apart; your connections to the gods and spirits will fill with static.

Take it slow. Start with something simple. When you have that down, add something else. Add things slowly and deliberately, in response to what you learn as you move along.

The breadth and depth you want will come with time, if you let it. Doing it all at once will only lead to burnout and failure.

Scanning the future: the startup behind chipless, metal-free, paper RFID tags - Positive News
Positive News
PulpaTronics is this year’s winner of the Green Alley Award. They design a metal-free and chipless RFID tags

"Clothing tags, travel cards, hotel room key cards, parcel labels … a whole host of components in supply chains of everything from cars to clothes. What do they have in common? RFID tags.  

Every RFID (Radio Frequency Identification) tag contains a microchip and a tiny metal strip of an antenna. A cool 18bn of these are made – and disposed of – each year. And with demands for product traceability increasing, ironically in part because of concerns for the social and environmental health of the supply chain, that’s set to soar. 

And guess where most of these tags end up? Yup, landfill – adding to the burgeoning volumes of e-waste polluting our soils, rivers and skies. It’s a sorry tale, but it’s one in which two young graduates of Imperial College London and Royal College of Art are putting a great big green twist. Under the name of PulpaTronics, Chloe So and Barna Soma Biro reckon they’ve hit on a beguilingly simple sounding solution: make the tags out of paper. No plastic, no chips, no metal strips. Just paper, pure and … simple … ? Well, not quite, as we shall see. 

The apparent simplicity is achieved by some pretty cutting-edge technical innovation, aimed at stripping away both the metal antennae and the chips. If you can get rid of those, as Biro explains, you solve the e-waste problem at a stroke. But getting rid of things isn’t the typical approach to technical solutions, he adds. “I read a paper in Nature that set out how humans have a bias for solving problems through addition – by adding something new, rather than removing complexity, even if that’s the best approach.”   

And adding stuff to a world already stuffed, as it were, can create more problems than it solves. “So that became one of the guiding principles of PulpaTronics”, he says: stripping things down “to the bare minimum, where they are still functional, but have as low an environmental impact as possible”.  

...how did they achieve this magical simplification? The answer lies in lasers: these turn the paper into a conductive material, Biro explains, printing a pattern on the surface that can be ‘read’ by a scanner, rather like a QR code. It sounds like frontier technology, but it works, and PulpaTronics have patents pending to protect it. 

The resulting tag comes in two forms: in one, there is still a microchip, so that it can be read by existing scanners of the sort common within retailers, for example. The more advanced version does away with the chip altogether. This will need a different kind of scanner, currently in development, which PulpaTronics envisages issuing licences for others to manufacture. 

Crucially, the cost of both versions is significantly cheaper than existing RFID kit – making this a highly viable proposition. Then there are the carbon savings: up to 70% for the chipless version – so a no-brainer from a sustainability viewpoint too. All the same, industry interest was slow to start with but when PulpaTronics won a coveted Dezeen magazine award in late 2023, it snowballed, says So. Big brands such as UPS, DHL, Marks & Spencer and Decathlon came calling. “We were just bombarded.” Brands were fascinated by the innovation, she says, but even more by the price point, “because, like any business, they knew that green products can’t come with a premium”."

Note: I know it's still in the very early stages, but this is such a relief to see in the context of the environmental and human rights bullshit associated with lithium mining, and the way that EVs and other green infrastructure are massively increasing the demand for rare metals.

I'll take a future with paper-based, more humane alternatives for sure! Fingers crossed this keeps developing and develops well (and quickly).

Having ADHD is a lot like being only able to travel with a hot air balloon. When the wind is right and the weather conditions are ideal, you can effortlessly go wherever you could possibly want, with almost no energy seemingly spent. And when the weather just Will Not Do That, there's nothing you can really do about it. Advice from people telling you to just fucking Grow Up And Learn To Steer don't believe you when you say you've got no steering wheel. Your explanations of navigating different wind directions at different altitudes make no sense to them.

So you just gotta accept that some days the wind goes your way, some days it won't. You can either exhaust yourself fighting the wind, accept that you're going nowhere at all today, or that the direction you are currently going is not the way you planned to go. Why am I in Uruguay.

I’m a young-adult woman with the hopes of becoming a well-known writer. I’m a dreamer, a music lover and a chaotic human being, curious about what the future will bring but without any idea of what to do with it. As for this tumblr, we’ll see. I will make an attempt to make an interesting place but for now I still have to figure out what to do with it.
