Replacing diesel school buses with electric school buses may yield up to $247,600 in climate and health benefits per individual bus, according to a new study by researchers at Harvard T.H. Chan School of Public Health. The ...
Tech Xplore / Can we rid artificial intelligence of bias?
Artificial intelligence built on mountains of potentially biased information has created a real risk of automating discrimination, but is there any way to re-educate the machines?
Tech Xplore / A promising three-terminal diode for wireless communication and optically driven computing
Two-terminal devices are electronic components connected to electrical circuits via two electrical terminals. Although these components are the key building blocks of most existing devices, they can limit a system's performance ...
Tech Xplore / Floating photovoltaics could limit Africa's future reliance on hydro-generated energy
Floating photovoltaics (FPV), also known as floating solar farms, are photovoltaic systems that can be deployed on the sea's surface or on other bodies of water. While their environmental impact is still the topic of debate ...
Tech Xplore / Researchers find LLMs are easy to manipulate into giving harmful information
A team of AI researchers at AWS AI Labs, Amazon, has found that most, if not all, publicly available Large Language Models (LLMs) can be easily tricked into revealing dangerous or unethical information.
Tech Xplore / The tentacles of retracted science reach deep into social media: A simple button could change that
In 1998, a paper linking childhood vaccines with autism was published in the journal, The Lancet, only to be retracted in 2010 when the science was debunked.
Tech Xplore / Orphan articles: The 'dark matter' of Wikipedia
Wikipedia is the largest platform for open and freely accessible knowledge online yet, in a new study, EPFL researchers have found that around 15% of the content is effectively invisible to readers browsing within Wikipedia. ...
Tech Xplore / Sun, sustainability, and silicon: A double dose of solar fuel research
The race is on to develop a new generation of liquid fuels that are activated by sunlight, and Yale researchers are helping to lead the way.
Tech Xplore / Q&A: Model disgorgement—the key to fixing AI bias and copyright infringement?
By now, the challenges posed by generative AI are no secret. Models like OpenAI's ChatGPT, Anthropic's Claude and Meta's Llama have been known to "hallucinate," inventing potentially misleading responses, as well as divulge ...
Tech Xplore / AI-powered noise-filtering headphones give users the power to choose what to hear
Noise-canceling headphones are a godsend for living and working in loud environments. They automatically identify background sounds and cancel them out for much-needed peace and quiet. However, typical noise-canceling fails ...
Tech Xplore / New browser extension empowers users to fight online misinformation
Most people agree that the spread of online misinformation is a serious problem. But there is much less consensus on what to do about it.
