May 9, 2025 Ben Popper chats with CTO Abby Kearns about how Alembic is using composite AI and lessons learned from contract tracing and epidemiology to help companies map customer journeys and understand the ROI of their marketing spend. Ben and Abby also talk about where open-source models have the edge and the challenges startups […]
Oregon State University College of Engineering researchers have developed a more efficient chip as an antidote to the vast amounts of electricity consumed by large-language-model artificial intelligence applications like Gemini and GPT-4. “We have designed and fabricated a new chip that consumes half the energy compared to traditional designs,” said doctoral student Ramin Javadi, who
The rules about magnetic order may need to be rewritten. Researchers have discovered that chromium selenide (Crâ‚‚Se₃) — traditionally non-magnetic in bulk form — transforms into a magnetic material when reduced to atomically thin layers. This finding contradicts previous theoretical predictions, and opens new possibilities for spintronics applications. This could lead to faster, smaller, and
Scientists have developed a new microscope that significantly improves the way heat flow in materials can be measured. This advancement could lead to better designs for electronic devices and energy systems. Measuring how heat moves through materials is crucial for developing efficient electronics and energy devices. For example, better heat management can lead to faster
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
In the 1660s, with the help of a simple, homemade light microscope that magnified samples more than 250 times, a Dutch fabric merchant named Antoine van Leeuwenhoek became the first person to document a close-up view of bacteria, red blood cells, sperm cells, and many other scientific sights. Since then, light microscopy has solidified its
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
