Consequently, participants answered more questions but were correct about a third as often as when AI was unavailable-yet their confidence nearly doubled. Incentivizing accuracy and penalizing inaccuracy led participants to seek and follow AI advice less, answer more accurately, and suspend judgment more often, though still far less than when AI was unavailable. As AI suggestions grow ubiquitous and unsolicited, they may not simply affect answer accuracy; they may even alter the metacognitive threshold at which people decide whether they know enough to answer.

Colpire un tumore fatto delle nostre stesse cellule è sembrato a lungo impossibile. Oggi però l'mRNA ha aperto nuove strade: nel melanoma è arrivato il primo successo, ma sono solo le prime parole di una nuova lingua che dobbiamo imparare.

When we think about security threats, we generally imagine them coming from far away across the wider internet. But what if the connection between you and your ISP was the target? [Rithwik Jayasimha] and [Rithvik Vibhu] have explored how fiber to the home connections may not be as secure as you would hope. The hack centers around fiber-to-the-home connections, of which many deployments rely on Gigabit Passive Optical Network (GPON) standards. The key there is the “passive” part—these networks don’t rely on active components to switch signals. ISPs run central trunk lines out to optical line terminals (OLT), with passive splitters installed in neighborhoods to serve a number of downstream subscribers. Each subscriber then has something called an Optical Network Unit (ONU) in their home, which filters out the traffic intended for that specific subscriber. Therein lies the flaw, though. Light (and thus, data) for _many_ subscribers flows into the home, and it’s only the ONU that is filtering that out. Hack the ONU, or replace it… and you have access to downstream traffic from your neighbors that you shouldn’t be able to access. The duo were able to hack an ONU to forward every single frame it receives, revealing downstream data intended for other homes in their immediate neighborhood. A great deal of traffic is encrypted these days, which provides a layer of safety, but it is by no means an ideal situation that such a hack is possible at all. They also explored other threats, such as installing splitters in publicly-accessible infrastructure, and compromising an upstream OLT and using it to flash firmware to other subscriber’s ONUs on the network. All this was presented in a talk at DEF CON, too, which can be viewed online. It’s a concerning look at an often unconsidered link in the network chain. Few of us expect our data to be snooped upon in between us and the ISP, after all. > Here's the link, we'll be streaming our talk @ 1PM PT > > If this breaks, it's Track 1 Main Stage on the #DEFCON YT channel https://t.co/nv0lzLkMwZ > > — Rithwik Jayasimha (@thel3l) August 8, 2026
