A new study published in the journal Dreaming found that using the Awoken lucid dreaming app significantly increased dream lucidity. Participants who used the app experienced a threefold increase in lucid dream frequency compared to a control group. The app employs techniques like reality testing reminders and dream journaling to promote lucid dreaming. This research suggests that smartphone apps can be effective tools for enhancing metacognition during sleep and inducing lucid dreams.
Researchers have developed a new transistor that could significantly improve edge computing by enabling more efficient hardware implementations of fuzzy logic. This "ferroelectric FinFET" transistor can be reconfigured to perform various fuzzy logic operations, eliminating the need for complex digital circuits typically required. This simplification leads to smaller, faster, and more energy-efficient fuzzy logic hardware, ideal for edge devices with limited resources. The adaptable nature of the transistor allows it to handle the uncertainties and imprecise information common in real-world applications, making it well-suited for tasks like sensor processing, decision-making, and control systems in areas such as robotics and the Internet of Things.
Hacker News commenters expressed skepticism about the practicality of the reconfigurable fuzzy logic transistor. Several questioned the claimed benefits, particularly regarding power efficiency. One commenter pointed out that fuzzy logic usually requires more transistors than traditional logic, potentially negating any power savings. Others doubted the applicability of fuzzy logic to edge computing tasks in the first place, citing the prevalence of well-established and efficient algorithms for those applications. Some expressed interest in the technology, but emphasized the need for more concrete results beyond simulations. The overall sentiment was cautious optimism tempered by a demand for further evidence to support the claims.
Voyager 1, currently over 15 billion miles from Earth, successfully transmitted data using a backup thruster control system not activated since 1981. NASA engineers recently rediscovered the system's functionality and tested it, confirming Voyager 1 can still send scientific data back to Earth via this alternative route. This extends the spacecraft's operational lifespan, though using the backup system requires slightly higher power consumption. While the primary thruster control system remains functional for now, this rediscovery provides a valuable backup communication method for the aging probe.
Hacker News commenters generally expressed awe and excitement at Voyager 1's continued operation and the ingenuity of the engineers who designed and maintain it. Several commenters highlighted the remarkable longevity and durability of the spacecraft, given its age and the harsh environment of interstellar space. Some discussed the technical details of the trajectory correction maneuver and the specific hardware involved, including the attitude control thrusters and the now-resurrected TCM thruster. A few questioned the phrasing of "breaking its silence," pointing out that Voyager 1 continues to send scientific data. Others reflected on the historical significance of the Voyager missions and the small, but important, course correction that ensures continued communication with Earth for a few more years.

Hacker News commenters discuss the efficacy and methodology of the lucid dreaming study. Some express skepticism about the small sample size and the potential for bias, particularly given the app's creators conducted the study. Others share anecdotal experiences with lucid dreaming, some corroborating the app's potential benefits, while others suggesting alternative induction methods like reality testing and MILD (Mnemonic Induction of Lucid Dreams). Several commenters express interest in the app, inquiring about its name (Awoken) and discussing the ethics of dream manipulation and the potential for negative dream experiences. A few highlight the subjective and difficult-to-measure nature of consciousness and dream recall, making rigorous study challenging. The overall sentiment leans towards cautious optimism, tempered by a desire for further, more robust research.
The Hacker News post discussing the lucid dreaming app study has generated a moderate amount of discussion, with several commenters sharing their experiences and perspectives on lucid dreaming and the app's efficacy.
Several commenters express skepticism about the study's methodology and the self-reported nature of lucid dreaming, highlighting the difficulty of objectively measuring such a subjective experience. One commenter questions the reliability of dream journals and suggests that the act of journaling itself, rather than the app, might contribute to increased dream recall and awareness. Another user points out the potential for recall bias and the placebo effect to influence the study's results. They propose a more rigorous study design involving physiological markers like REM sleep and eye movements to corroborate self-reported lucid dreams.
Some users share personal anecdotes about their experiences with lucid dreaming, both with and without the aid of apps. One commenter mentions successfully inducing lucid dreams through reality testing techniques and emphasizes the importance of consistent practice. Another user recounts their experiences with the app mentioned in the article, noting its helpfulness in improving dream recall but expressing skepticism about its ability to directly induce lucidity. A few users discuss the potential benefits of lucid dreaming, such as overcoming nightmares and exploring creative ideas.
A thread develops around the ethics of using technology to influence dreams, with one commenter raising concerns about the potential for manipulation and addiction. Others express interest in the potential therapeutic applications of lucid dreaming, such as treating PTSD and anxiety disorders.
Several commenters discuss alternative methods for inducing lucid dreaming, including mnemonic induction of lucid dreams (MILD) and wake back to bed (WBTB) techniques. They also mention other apps and resources available for those interested in exploring lucid dreaming.
Finally, some commenters offer practical advice for aspiring lucid dreamers, such as maintaining a regular sleep schedule, keeping a dream journal, and practicing reality testing techniques throughout the day. One commenter even suggests incorporating a "dream totem," a physical object used as a cue to recognize the dream state.
