An edible robot made by EPFL scientists leverages a combination of biodegradable fuel and surface tension to zip around the water’s surface, creating a safe — and nutritious — alternative to environmental monitoring devices made from artificial polymers and electronics. The boat-shaped robot takes advantage of the same phenomenon — the Marangoni effect — used […]
The proliferation of GenAI tools continues to compel us to critically reassess how we gauge success in the modern digital age. Like other transformative technologies before it, the rise of AI necessitates a shift in our focus. The future vitality of the internet and the broader tech ecosystem will no longer be solely defined by
In line with the other work we’re doing, we’re embarking on a rebrand process—here’s why. When Stack Overflow (and later, Stack Exchange) started, its mission was clear and focused. But the world has changed. Fast. Artificial intelligence is reshaping how we build, learn, and solve problems. Software development looks dramatically different than it did even
May 8, 2025 How can engineering teams move beyond traditional metrics like velocity to create real business impact? In this episode of Leaders of Code, Dan Lines, cofounder and COO of LinearB; Ben Matthews, Senior Director of Engineering at Stack Overflow; and host Ben Popper talk about why velocity should be a diagnostic tool, not
Imagine you are playing the guitar — each pluck of a string creates a sound wave that vibrates and interacts with other waves. Now shrink that idea down to a small single molecule, and instead of sound waves, picture vibrations that carry heat. A team of engineers and materials scientists in the Paul M. Rady
A portable device that can instantly detect dangerous street drugs at extremely low concentrations has been developed at the University of Bath in the UK. The device, which is being trialled by drug-checking services in the UK, Norway and New Zealand, can identify substances such as benzodiazepines and synthetic opioids that are difficult to detect
Engineers from Australia and China have invented a sponge-like device that captures water from thin air and then releases it in a cup using the sun’s energy, even in low humidity where other technologies such as fog harvesting and radiative cooling have struggled. The water-from-air device remained effective across a broad range of humidity levels
Scientists at the University of Southern California (USC) have developed a lactation pad equipped with sensing technology that allows parents of newborns to monitor breast milk in real time. Publishing in the Cell Press journal Device on May 7, their work shows that the device is capable of ensuring that breast milk contains safe levels
A research team led by Professor Yong-Young Noh and Dr. Youjin Reo from the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology) has developed a groundbreaking technology poised to revolutionize next-generation displays and electronic devices. The project was a collaborative effort with Professors Ao Liu and Huihui Zhu from the University
Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery by McGill University researchers that challenges conventional wisdom in physics suggests that bismuth, a metal, could serve as the foundation for highly stable electronic components. The researchers observed a mysterious electrical effect in ultra-thin bismuth
