Tech Xplore / Chatbots may fuel 'delusional spirals' that lead to real-world harm
Perhaps to the surprise of their creators, large language models have become confidants, therapists, and, for some, intimate partners to real human users. In a new study, AI researchers at Stanford studied verbatim transcripts ...
Tech Xplore / Wastewater sludge treatment boosts renewable natural gas 200% and halves disposal costs
A pilot study of a new method for treating sewage sludge from a wastewater treatment plant efficiently created renewable natural gas while reducing the cost of the treatment. The work, reported in the Chemical Engineering ...
Tech Xplore / From Siri to scams, AI voice clones now beat human speech in noisy settings
Synthetic voices are increasingly a part of our lives, from digital assistants like Siri and Alexa to automated telemarketers and answering machines. With the expansion of generative AI, a new type of synthetic voice has ...
Tech Xplore / A truly invisible device that does not disturb its surroundings and its metamaterial shell
Metamaterials are carefully engineered materials that possess desirable properties and can be used to manipulate electromagnetic, acoustic, or other types of waves in interesting ways. Some materials scientists and engineers ...
Tech Xplore / This 'gas battery' turns CO₂ and NOₓ pollution into electricity while cleaning the air
A research team has introduced a new concept device termed the Gas Capture and Electricity Generator (GCEG), which produces electrical power as greenhouse gases are adsorbed from the atmosphere. This innovation goes beyond ...
Tech Xplore / Handle with care: Soft robot gripper picks ripe fruit without bruising
When assessing the ripeness of fruit, sight and smell can tell you a lot, but the best indicator is often how the fruit feels. Cornell researchers used stretchable fiber-optic sensors to create a soft robot gripper that can ...
Tech Xplore / Biowaste coatings made from crustacean shells can boost CO₂-to-fuel conversion
The stranglehold on the Strait of Hormuz in the past few weeks has choked off roughly a fifth of the world's oil supply, triggering the worst global energy crisis since the 1970s. Beyond the immediate shock, the disruption ...
Tech Xplore / Fusion power may never be cost-competitive with renewables, study warns
Fusion power plants are sites at which electricity could be generated via a process known as nuclear fusion, which entails the merging of two atomic nuclei into a single heavier nucleus. This process is known to generate ...
Tech Xplore / Engineered wood provides solar power even after the sun goes down
While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of ...
Tech Xplore / A humanoid robot sprints past the human half-marathon world record in Beijing race
A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China's technological leaps.
Tech Xplore / Perovskite solar cells reach 26.61% certified efficiency with cesium-doping strategy
Solar cells, devices that convert sunlight into electricity, are now widely used in many countries. While most existing solar cells are based on silicon, energy engineers have been working on other devices made of so-called ...
Tech Xplore / Unpredictable AGI may resist full control, making diverse AI safer
Public concern about AI safety has grown significantly in recent years. As AI systems become more powerful, a key question is how we make sure they do what we actually want. Now, researchers suggest that rather than trying ...
