Wearable Nanotech Could Combat Nerve Agents

alternative_right shares a report from Phys.org: Nanoparticles could someday provide a new way to help soldiers fight back against deadly nerve agents on the front lines. In a new study, Northwestern University scientists developed a nanoparticle-based compound that, when mixed into clothing dyes, could limit the impact of chemicals commonly found in pesticides, insecticides and nerve agents. Manufacturers could potentially add the nanoparticles to clothing used by those most at risk, such as farmers' masks and gloves or soldiers' uniforms and tactical gear. Or, if someone is exposed to a potentially deadly chemical, they could spray their clothing with water mixed with the compound to deactivate the chemical before its damaging effects take hold. The study has been published in the journal ACS Nano.

The Night Sky Is Getting 10% Brighter Every Year

fjo3 quotes a report from The Guardian, written by Tove Danovich: Every year, the night sky is becoming 10% brighter. Eighty percent of people live under light-polluted skies. And while the UN declared a healthy environment -- clean air, clean water -- to be a human right, I believe we also all have a right to darkness as well. This doesn't mean turning off every streetlamp. But do we really need bright white floodlights at the front of every garage? Replacing lights with ones that are bright enough to do the job -- and no brighter -- might make it so I wouldn't have to get in my car and drive for hours to see the night sky as it actually shines above us. To preserve the darkness would mean rules and enforcement around the warmth of the lights, where they point, and how bright they can be. It would mean not putting in three lights when one would do. If we recognized that darkness is something we need, we'd become more careful about chasing it away. [...] Access to darkness is about more than stargazing. The night is its own habitat. Artificial lights confuse animals who use the moon to navigate, whether they're baby sea turtles navigating toward a parking lot instead of the ocean or moths who fly in circles around a lightbulb. Lightning bugs and frogs need darkness to complete their courtship rituals. Migrating birds get thrown off course by the bright lights of big cities. But the effects of light pollution linger even after it's daylight again, becoming visible. Research has shown light pollution is breaking the relationship between plants and pollinators, changing the time of year trees break into flower, and disrupting circadian rhythms for all living creatures. This includes humans. Whether it's artificial lights indoors or creeping in through the window at night, studies have found that we need darkness in order to rest, recover and stay healthy.

Tech Workers Made ChatGPT Drive a Toyota Corolla

An anonymous reader quotes a report from 404 Media: Some tech workers in San Francisco hooked up ChatGPT to a Toyota Corolla and got it to drive around a parking lot. This may not sound impressive in the age of the self-driving car until you realize that the LLM driving the car was a general purpose chatbot running on a laptop and not the purpose-built driving system based on millions of hours of training data used by Waymo or Tesla. The people behind the stunt call themselves DrivingBench and they've posted their code, their prompts, and videos of the experiment online. In the experiment, DrivingBench hooked up GPT-6 Astra, Claude Fable 5.1, Grok 4.6, and GPT-5.6 Sol to a Toyota Corolla and gave the LLMs control over the car's steering, accelerator, and brakes. Then they set up a small cone course in a public parking lot and prompted the chatbots to navigate the space. The goal, they said, was to find out if untrained, off-the-shelf frontier AIs can drive a real car. The results were mixed. Grok, Sol, and Fable only drove a few meters and didn't finish the course. GPT-6 Astra, however, did eventually learn to navigate the course and complete it. But not without a lot of troubleshooting. "It's an interesting demonstration of potential emergent capabilities," said Mahns. "It can fail a turn, and then the next turn, next try, it will be able to do that turn and other turns that it hasn't seen before. Not necessarily saying LLMs are gonna put Waymo out of business or something, just an interesting demonstration of where things are, and things are just moving fast." "Most people that are familiar with ChatGPT have used it in this white collar, kind of like in the computer, and it's definitely imminent to the point that this capability will start having more impact in the physical world. So I think seeing the sparks of this happening, the shift of this utility coming into the physical world, is also somewhat exciting."
