Despite predictions that AI would replace radiologists, healthcare systems worldwide are hiring more of them because AI tools enhance their work, create new oversight tasks, and increase imaging volumes rather than reducing workloads. "Put all that together with the context of an aging population and growing demand for imaging of all kinds, and you can see why Offiah and the Royal College of Radiologists are concerned about a shortage of radiologists, not their displacement," writes Financial Times authors John Burn-Murdoch and Sarah O'Connor. Amaka Offiah, who is a consultant pediatric radiologist and a professor in pediatric musculoskeletal imaging at the University of Sheffield in the UK, makes a prediction of her own: "AI will assist radiologists, but will not replace them. I could even dare to say: will never replace them." From the report: [A]lmost all of the AI tools in use by healthcare providers today are being used by radiologists, not instead of them. The tools keep getting better, and now match or outperform experienced radiologists even after factoring in false positives or negatives, but the fact that both human and AI remain fallible means it makes far more sense to pair them up than for one to replace the other. Two pairs of eyes can come to a quicker and more accurate judgment, one spotting or correcting something the other missed. And in high-stakes settings where the costs of a mistake can be astronomical, the downside risk from an error by a fully autonomous AI radiologist is huge. "I find this a fascinating demonstration of why even if AI really can do some of the most high-value parts of someone's job, it doesn't mean displacement (even of those few tasks let alone the job as a whole) is inevitable," concludes John. "Though I also can't help noticing a parallel to driverless cars, which were simply too risky to ever go fully autonomous until they weren't."

Sarah added: "I think the story of radiologists should be a reminder to technologists not to make sweeping assertions about the future of professions they don't intimately understand. If we had indeed stopped training radiologists in 2016, we'd be in a real mess today."

alternative_right shares a report from ScienceAlert: Engineers at Cornell University have created the blackest fabric on record, finding it absorbs 99.87 percent of all light that dares to illuminate its surface. [...] In this case, the Cornell researchers dyed a white merino wool knit fabric with a synthetic melanin polymer called polydopamine. Then, they placed the material in a plasma chamber, and etched structures called nanofibrils -- essentially, tiny fibers that trap light. "The light basically bounces back and forth between the fibrils, instead of reflecting back out -- that's what creates the ultrablack effect," says Hansadi Jayamaha, fiber scientist and designer at Cornell.

The structure was inspired by the magnificent riflebird (Ptiloris magnificus). Hailing from New Guinea and northern Australia, male riflebirds are known for their iridescent blue-green chests contrasted with ultrablack feathers elsewhere on their bodies. The Cornell material actually outperforms the bird's natural ultrablackness in some ways. The bird is blackest when viewed straight on, but becomes reflective from an angle. The material, on the other hand, retains its light absorption powers when viewed from up to 60 degrees either side. The findings have been published in the journal Nature Communications.

Found it by the roadside, wings still neat, eyes already gone. I hesitated before taking the shot, then realised hesitation was the whole point. Beauty and decay never stay in their lanes.

I’d been watching them for a while, waiting for order to happen. Three aligned, the fourth ruined it, which made the shot work. Nature does symmetry better than I do, but only when it stops trying.
