10 Things In Technology News Today
1. Alexa Guard: Amazon has officially dropped Alexa Guard, a feature that allowed Alexa devices to listen for smoke and carbon monoxide detectors or breaking glass, and alert users of potential emergencies. The feature is now folded into Alexa Emergency Assist, a subscription service that costs $5.99 per month.
In Other News:
2. ChatGPT ‘Laziness’: OpenAI has announced a preview fix for ChatGPT, a popular conversational AI model that was criticized for being ‘lazy’ and not completing tasks. The fix involves adding a reward signal to the model, which encourages it to generate more informative and relevant responses.
3. Organic Semiconductors: A new method for creating organic semiconductors has been developed, using a sustainable and scalable process that does not require toxic solvents or high temperatures. Organic semiconductors have advantages over conventional ones, such as flexibility, biocompatibility, and tunability.
4. Artificial Muscle Device: A team of engineers has designed an artificial muscle device that produces force 34 times its weight. The device is made of carbon nanotubes and rubber, and can be controlled by electric voltage. The device could enable new applications in robotics, prosthetics, and wearable devices.
5. Brain-Like Transistor: Scientists have created a new type of transistor that mimics human intelligence beyond silicon. The device can perform complex computations, learn from data, and adapt to changing environments. This could revolutionize artificial intelligence, neuromorphic computing, and brain-computer interfaces.
6. AI’s Achilles Heel: A new study has identified fundamental weaknesses in artificial intelligence, such as the inability to generalize across domains, the lack of common sense, and the susceptibility to adversarial attacks. The study also proposes possible solutions to overcome these challenges, such as incorporating causal reasoning, human feedback, and robustness measures.
7. Compressed Sensing: Researchers have developed a new technique for compressed sensing, which enables faster and more accurate reconstruction of sparse signals from incomplete measurements. Compressed sensing is a key technology for efficient data acquisition and processing in fields such as medical imaging, radar, and wireless communication.
8. Meta-Optical Technology: A novel technology that uses metasurfaces to manipulate light has been developed, which can transform thermal imaging. The technology can gather more intricate thermal data, which could enhance autonomous navigation, material recognition, security, and other applications.
Odds and Ends:
9. Invisible Armor for Steel: Researchers have developed a coating of hexagonal boron nitride (hBN) that enhances the durability, reduces the friction, and protects against harsh conditions of metal alloys. This could improve the performance of solar panels, semiconductors, and other applications.
10. Perovskite Solar Cell Breakthrough: Korean researchers have set new efficiency records for perovskite solar cells, reaching 25.6% for a single-junction cell and 29.5% for a tandem cell. Perovskite solar cells are cheaper, easier, and faster to produce than conventional silicon solar cells, and have the potential to surpass their performance.
