Simulating a Worm Brain: A Stepping Stone to Whole-Brain Emulation?

2025-04-01

Simulating the human brain has been a holy grail of science, but its complexity has proven daunting. Scientists have turned to C. elegans, a nematode with only 302 neurons. After 25 years and numerous failed attempts, simulating its brain is finally within reach thanks to advancements in light-sheet microscopy, super-resolution microscopy, and machine learning. These technologies enable real-time observation of neural activity in living worm brains and use machine learning to infer the biophysical parameters of neurons. Successfully simulating a C. elegans brain would not only be a remarkable scientific achievement but also provide invaluable experience and methods for simulating more complex brains, ultimately including human brains, paving the way for future AI and neuroscience research.

Cutting Science Funding: A Costly Mistake

2025-02-25

The Trump administration's "Department of Government Efficiency" has frozen funding for the National Science Foundation and the National Institutes of Health, raising concerns about cuts to federally funded scientific research. The article uses the example of massage therapy for premature infants to demonstrate how seemingly odd basic science research can yield enormous social and economic benefits. It argues for the importance of long-term government investment in basic science and the need for reforms to research funding mechanisms. While short-term returns are unpredictable, history shows that investments in basic science offer high returns and are a worthwhile long-term strategy.

Bezos's 10,000-Year Clock: A Monument to Long-Term Thinking or a Tech Billionaire's Ego Project?

2025-02-09

Jeff Bezos funded the construction of a massive mechanical clock designed to run for 10,000 years, nestled in the Texas mountains. This article delves into the story behind this ambitious project, exploring its design, construction, symbolism, and societal implications. Danny Hillis, the clock's creator, envisioned it as a symbol to inspire long-term thinking, while the Long Now Foundation aims to preserve human knowledge to mitigate the risks of technological singularity. However, Bezos's involvement has sparked debate, questioning whether the project has deviated from its original idealistic goals. The article ultimately explores the tension between technological advancement and long-term planning, and how to balance progress with the sustainable future of humanity.

X's Community Notes: Building a Community to Combat Misinformation

2025-01-20

The team behind X's (formerly Twitter) Community Notes shares their design process and philosophy for combating misinformation on the platform. Initially observing the difficulty in accessing accurate information online, they moved beyond traditional methods (internal review teams or media partnerships) which suffered from speed, scale, and trust issues. Inspired by Wikipedia's crowdsourced model, they developed Community Notes: users submit specific notes addressing individual posts, and an algorithm filters for notes deemed helpful across the political spectrum. This algorithm analyzes user voting history, identifying notes that bridge disagreements even among opposing viewpoints. Years of iteration and piloting led to a global rollout, significantly reducing misinformation spread and boosting user trust.
