Tech Xplore / How AI models successfully detect personality traits from written text
A research team at the University of Barcelona (UB) has shown how artificial intelligence (AI) models can detect personality traits from written texts, and for the first time has managed to analyze in detail how these systems ...

Tech Xplore / Pervasive surveillance of people is being used to access, monetize, coerce and control, study suggests
New research has underlined the surprising extent to which pervasive surveillance of people and their habits is powered by computer vision research—and shone a spotlight on how vulnerable individuals and communities are ...

Tech Xplore / Li-Fi technology offers enhanced security and speeds 100 times faster than Wi-Fi
Li-Fi (Light Fidelity) is a wireless communication technology that utilizes the visible light spectrum (400–800 THz), similar to LED light, offering speeds up to 100 times faster than existing Wi-Fi (up to 224 Gbps). While ...

Tech Xplore / Noninvasive ultrasound technique can spot bad batteries before they malfunction
A recent uptick in battery-related fires has drawn attention to the challenge of identifying defects that can cause these catastrophic malfunctions, but are rarely obvious to the naked eye. In hopes of preventing the dangerous ...

Tech Xplore / Compute-in-memory chip shows promise for enhanced efficiency and privacy in federated learning systems
In recent decades, computer scientists have been developing increasingly advanced machine learning techniques that can learn to predict specific patterns or effectively complete tasks by analyzing large amounts of data. Yet ...

Tech Xplore / Turning captured carbon into natural gas could provide cost-competitive energy storage
Solar and wind energy are highly variable, dependent on the day, weather and location of the facilities. At times, they can generate more electricity than is needed, but they can also fall short when demand is at its peak. ...

Tech Xplore / Sustainable cooling film could slash building energy use by 20% amid rising global temperatures
An international team of scientists has developed a biodegradable material that could slash global energy consumption without using any electricity, according to a new study published today.

Tech Xplore / US judge backs using copyrighted books to train AI
A US federal judge has sided with Anthropic regarding training its artificial intelligence models on copyrighted books without authors' permission, a decision with the potential to set a major legal precedent in AI deployment.

Tech Xplore / Modified perovskite solar cells harvest energy from indoor fluorescent lighting
When you think of solar panels, you usually picture giant cells mounted to face the sun. But what if "solar" cells could be charged using fluorescent lights?

Tech Xplore / AI and humans see objects differently: Meaning versus visual features
While humans concentrate on the meaning of objects, artificial intelligence focuses on visual characteristics.

Dialog / Triazatruxene hole transport layers enhance the performance of Sb₂(S,Se)₃ solar cells
Antimony selenosulfide (Sb2(S,Se)3) solar cells are emerging as a strong candidate for next-generation thin-film photovoltaics due to their tunable bandgap, strong optical absorption and composition from Earth-abundant, nontoxic ...

Tech Xplore / New research reveals Uber's algorithmic pricing leaves drivers and passengers worse off
A new study from researchers in the University of Oxford's Department of Computer Science has found that Uber's use of dynamic pricing has led to higher fares for passengers and lower earnings for drivers, while increasing ...
