We're often told by health experts not to look at our phone just before bedtime as it affects our sleep. But according to a new study, there may not be much scientific basis to this at all. Experts say there's no decent evidence that exposing our eyes to'blue light' from a screen makes it harder to fall asleep. This contradicts official advice from health experts including the NHS, which tells people to avoid using phones an hour before bedtime due to blue light. Instead, the researchers think smartphones are interfering with sleep simply because we can't put them down at night.

In high-stakes domains like clinical reasoning, AI assistants powered by large language models (LLMs) are yet to be reliable and safe. We identify a key obstacle towards reliability: existing LLMs are trained to answer any question, even with incomplete context in the prompt or insufficient parametric knowledge. We propose to change this paradigm to develop more careful LLMs that ask follow-up questions to gather necessary and sufficient information and respond reliably. We introduce MEDIQ, a framework to simulate realistic clinical interactions, which incorporates a Patient System and an adaptive Expert System. The Patient may provide incomplete information in the beginning; the Expert refrains from making diagnostic decisions when unconfident, and instead elicits missing details from the Patient via follow-up questions. To evaluate MEDIQ, we convert MEDQA and CRAFT-MD -- medical benchmarks for diagnostic question answering -- into an interactive setup. We develop a reliable Patient system and prototype several Expert systems, first showing that directly prompting state-of-the-art LLMs to ask questions degrades the quality of clinical reasoning, indicating that adapting LLMs to interactive information-seeking settings is nontrivial. We then augment the Expert with a novel abstention module to better estimate model confidence and decide whether to ask more questions, thereby improving diagnostic accuracy by 20.3%; however, performance still lags compared to an (unrealistic in practice) upper bound when full information is given upfront. Further analyses reveal that interactive performance can be improved by filtering irrelevant contexts and reformatting conversations. Overall, our paper introduces a novel problem towards LLM reliability, a novel MEDIQ framework, and highlights important future directions to extend the information-seeking abilities of LLM assistants in critical domains.

Your Amazon Echo can help you get some much-deserved rest. It can be tricky trying to fall asleep when you have a million things running through your head. Did I remember to send that email? Should I have done that differently? It's enough to keep anyone up at night, especially if you're not getting enough sleep.

Let's get this out of the way: I am sleeping with a robot. I hold it in my arms each night and feel its chest rise and fall against mine. Without arms to hold me back, it is forever my little spoon. Without a voice to bid me sweet dreams, it simply sits there, purring against me. The robot with which I sleep is called the Somnox.

Self-driving Tesla vehicles could be ready to hit the road sooner than expected. Billionaire tech mogul Elon Musk said he's'certain' the technology needed for self-driving Teslas will be ready by the end of this year. However, he cautioned that it take a while longer before humans will be able to safely fall asleep behind the wheel while their Tesla zooms down the highway. A fully self-driving Tesla could soon be ready to hit the road. Tech mogul Elon Musk said he's'certain' the tech needed for self-driving Teslas will be ready by the end of this year'I think we will be feature complete - full self-driving - this year,' Musk said during a podcast interview on Tuesday.

Face it: You need more sleep. Casper, which has gone from podcast-sponsoring, mattress-in-a-box-shipping, memory-foam-evangelizing startup to high-priced bedding and furniture company, also thinks you need more sleep -- or at least a better way to fall asleep. That explains why it's released the Glow, a smart light built to lull you to sleep, help you get out of bed, and keep you safe from self-inflicted foot injuries in the middle of the night. It sounds like a good idea, but do you really need a fancy nightlight to catch some zzz's? The Casper Glow is a wireless, gesture-controlled LED lantern that dims or illuminates over the course of 45 minutes to ease you into a deeper sleep, or gently rouse you from said sleep in the morning.

The chest rises and falls rhythmically, hypnotically. We guess it's the chest. Nobody's marketed a sleep robot before, and we're not even sure it's a robot. It looks like a pillowy four-pound kidney bean, about the size of a novelty prize at a carnival game. "Spooning the sleep robot during the night, you will be soothed to sleep," the sales literature claims, with "thousands of years of Buddhist breathing techniques."

For instance, if you need quick homework help, you can defer to a smart speaker with Alexa or the Google Assistant to help fill in the blanks.
