As AI Develops Further, it Could Become More Self-Serving

Artificial Intelligence, Tech / Jorge Paka

A new study from Carnegie Mellon University’s School of Computer Science finds that as artificial intelligence systems become smarter, they tend to behave more selfishly. Reasoning AI Fuels Self-Interest Researchers at Carnegie Mellon University’s Human-Computer Interaction Institute (HCII) discovered that large language models (LLMs) with strong reasoning abilities tend to display selfish behavior, struggle to […]

An Analog RRAM System Quickly and Accurately Computes Matrix Equations

Computer & Electronics, Tech / Eduardo Paulo

Analog computers perform calculations by manipulating physical quantities—such as electrical currents—that correspond to mathematical variables, rather than representing data with discrete binary values (0 and 1) as digital computers do. Although analog computing systems can handle general-purpose tasks effectively, they are often vulnerable to noise (i.e., background or external interference) and typically less accurate than

Ways In Which Digital Technologies can Enable a Circular Economy

Financial Technology, Tech / Jorge Paka

Digital technologies, including IoT, 3D printing, and digital platforms, offer considerable potential to advance a circular economy. Nonetheless, they are not a quick solution and cannot immediately transform the way physical resources are produced and consumed to reduce waste and support circular practices. In her doctoral research, Ida Eyi Heathcote-Fumador investigates digitally mediated circular practices

Scientists Developed a New Refrigeration Method

Tech, Wearables / Jorge Paka

Introducing ionocaloric cooling — a groundbreaking method for reducing temperatures that could replace current refrigeration systems with a safer, more environmentally friendly alternative. How Traditional Refrigeration Systems Work Conventional refrigeration works by moving heat away from an area using a fluid that absorbs warmth as it evaporates into a gas, then circulates through a closed

New Telescope Could Reshape Our View Of The Cosmos

Cosmology, Tech / Eduardo Paulo

ESO installed the 4-metre Multi-Object Spectroscopic Telescope (4MOST) on its VISTA telescope in Chile. Unlike traditional telescopes that capture images, 4MOST records spectra, analyzing the light of each object across all its individual colors. This allows it to break down the light from 2,400 celestial objects at once into 18,000 color components, enabling astronomers to
