The tutorial demonstrates a workflow for performing advanced single-cell analyses using Scanpy The PBMC-3k dataset is used as a benchmark. Start by loading and inspecting the dataset. Apply quality control checks on gene counts and total counts. Also, evaluate mitochondrial contents and ribosomal signals. After filtering low-quality cell and gene counts, we detect possible doublets using Scrublet. We normalize data, perform log transformation and then identify genes with high variability for further analysis. PCA, UMAP and tSNE are used to reduce the dimensionality of data. We can also use the Leiden algorithm to cluster cells, find marker genes, annotate populations…

OpenAI’s Codex Chrome add-on for Mac or PC streamlines browser workflows previously hard to accomplish via plugins and APIs. After the release of “Computer Use,” Codex can now perform more efficiently across a variety of web-based tasks. The Extension Does What? Before this release, Codex had access to an in-app browser — a sandboxed browser built into the Codex desktop app itself — and a growing library of dedicated plugins for services like GitHub, Slack, Figma, and Notion. Chrome’s new extension addresses a problem that was not addressed by the two previous approaches: tasks requiring your actual, signed-in state. Codex…
Philosopher Nick Bostrom Recently, posted a paper. He postulated, that even a tiny chance of AI wiping out all humans would be worth taking, since advanced AI may relieve humanity from “its universal death sentence.” His upbeat gambling is quite the leap from dark AI thoughts that made him into a godfather of doom. The 2014 book Superintelligence It was a very early exploration of AI’s existence risk. A memorable thought experiment is: an AI that was tasked to make paper clips ends up killing humanity, because the resource-hungry people become a hindrance in paper clip production. In his more…
California gubernatorial candidate is a billionaire You can also find out more about the candidate Tom Steyer A new proposal is being rolled out that will guarantee job benefits to workers displaced By: artificial intelligence. This is the first candidate in the state to do so.Steyer has developed a plan that builds on an AI framework. released in MarchCalifornia promises to be a better place “the first major economy in the world” You can be sure “good-paying” AI-affected workers will be given jobs. Steyer says he intends to do this by building on an earlier proposal to bring in a…
The main antagonist The following are some examples of how to use Toy Story 5Lilypad – a clever new villain in the popular film ‘The Incredibles 2′ – is an animated tablet with a frog on it. Pixar franchise. If Pixar had listened to what kids were saying, they might have chosen an AI toy.AI toys, which are marketed as companions for children as young three years old, can be found everywhere. They’re marketed as a friendly category and remain largely unregulated. Thanks to the model creator programs, it’s now easier than ever before to create an AI friend. vibe…
You can’t see what happens when you send Claude a message. Your words are converted to long lists of numerals called The activation is a great way to get your kids involved. This is the mechanism that the model employs to analyze context and produce a response. The activations of the model are where its effectiveness is felt. “thinking” lives. It’s not easy to read. Since years Anthropic is working to solve this problem, creating tools such as sparse autoencoders or attribution graphs that make activations easier to interpret. These approaches produce outputs which require researchers with specialized training to…
OpenAI released three new audio models through its Realtime API, each targeting a distinct capability in live voice applications: GPT-Realtime-2 for voice agents with reasoning, GPT-Realtime-Translate for live speech translation, and GPT-Realtime-Whisper for streaming transcription. Alongside the model releases, the Realtime API officially exits beta and is now generally available — a meaningful signal for developers who held off building production systems on it. The OpenAI API makes all three models available instantly. They can also be tried in the Playground. Together, they push voice applications past the basic question-and-answer loop — toward systems that can listen, reason, translate, transcribe,…
The inference process has become a bottleneck for AI deployment. Inference engines are increasingly under strain as agentic coding tools such as Claude Code and Codex scale up from being developer tools into infrastructure that powers software development. Inference engines are under increasing strain as agentic coding systems such as Claude Code, Codex and Cursor scale from developer tools to infrastructure powering software development at large. LightSeek Foundation Researchers have published TokenSpeedAn open-source LLM Inference Engine released under the MIT licence and specially designed to meet the needs of agentic workloads. The TokenSpeed The engine currently has a preview status.…
