This Giant Subterranean Neutrino Detector Is Taking On the Mysteries of Physics

Located 700 meters underground near the city of Jiangmen in southern China, a giant sphere—35 meters in diameter and filled with more than 20,000 tons of liquid—has just started a mission that will last for decades. This is Juno, the Jiangmen Underground Neutrino Observatory, a new, large-scale experiment studying some of the most mysterious and elusive particles known to science. Neutrinos are the most abundant particles in the universe with mass. They are fundamental particles, meaning they d

NASA's latest mission to the ISS features a bacterial experiment

Scientists are sending several strains of disease-causing bacteria to the International Space Station as part of the Crew-11 mission. This experiment isn't the plot to some cheesy horror film, but a scientific investigation from the Sheba Medical Center in Israel and the US-based company Space Tango with the goal of better understanding how bacteria spread and behave under extreme conditions. The experiment includes E. coli, along with bacteria that cause diseases like typhoid fever and the infe

Double-slit experiment holds up when stripped to its quantum essentials

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of light. They also happen to confirm that Albert Einstein was wrong about this particular quantum scenario. The experiment in question is the double-slit experiment, which was first performed in 1801 by the British scholar Thomas Young to show how light behaves as a wave. Today, with the formulation of

ReproZip – reproducible experiments from command-line executions

ReproZip ReproZip is a tool aimed at simplifying the process of creating reproducible experiments from command-line executions, a frequently-used common denominator in computational science. It tracks operating system calls and creates a package that contains all the binaries, files and dependencies required to run a given command on the author's computational environment (packing step). A reviewer can then extract the experiment in his environment to reproduce the results (unpacking step). Q

YouTube’s latest experiment makes comments feel more like Reddit, if that sounds like an improvement

Joe Maring / Android Authority TL;DR YouTube is rolling out Reddit-style comment threading to Premium subscribers on Android and iOS. The experiment has been updated so the main comment is threaded to subsequent replies. Threaded comments will remain available until August 14. YouTube’s comments section is going to look a little different for Premium subscribers. The company is rolling out an experiment inspired by Reddit. Earlier this year, YouTube began testing a new threaded comment UI f

Running TypeScript Natively in Node.js

Since v23.6.0, Node.js enables "type stripping" by default. If you are using v23.6.0 or later and your source code contains only erasable typescript syntax, you do not need this article. Since V22.6.0, Node.js has experimental support for some TypeScript syntax via "type stripping". You can write code that's valid TypeScript directly in Node.js without the need to transpile it first. The --experimental-strip-types flag tells Node.js to strip the type annotations from the TypeScript code before

New quantum paradox clarifies where our views of reality go wrong (2018)

That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a century is just what it’s telling us about what exists, what is real. There are myriad interpretations that offer their own take on the question, each requiring us to buy into certain as-yet-unverified claims — hence assumptions — about the nature of reality. Now, a new thought experiment is confro

We ran a Unix-like OS on our home-built CPU with a home-built C compiler (2020)

How we ran a Unix-like OS (Xv6) on our home-built CPU with our home-built C compiler [Thanks for many comments and votes on Hacker News! ] It’s been two years since I started working as a software engineer. I sometimes tell my colleagues about a student project I did in my junior year of university, and it’s so well-received that I’m writing this post. Now, let me ask you a question. Have you ever designed your own ISA, built a processor of that ISA on FPGA, and built a compiler for it? Furth

Sailing the fjords like the Vikings yields unexpected insights

Experimental archaeologist Greer Jarrett of Lund University in Sweden has been sailing in the footsteps of Vikings for the last three years. If you want to learn more about how and where the Vikings sailed, making the journey through the fjords yourself in replica boats is a practical, hands-on approach to achieving that end. Greer Jarrett, an archaeologist at Lund University in Sweden, has spent the last three years doing just that, sailing more than 5,000 kilometers along known Viking trade r

Wikipedia pauses AI-generated summaries pilot after editors protest

In Brief Wikipedia has reportedly paused an experiment that used AI to summarize articles on its platform after editors pushed back. Wikipedia announced earlier this month it was going to run the experiment for users who have the Wikipedia browser extension installed and chose to opt in, according to 404 Media. AI-generated summaries appeared at the top of every Wikipedia article with a yellow “unverified” label. Users had to click to expand and read them. Editors almost immediately criticize
