An OpenAI research team fine-tunes the GPT-3 pretrained language model to enable it to answer long-form questions by searching and navigating a text-based web browsing environment, achieving retrieval and synthesis improvements and reaching human-level long-form question-answering performance.
When the results of his study came in, Kondwani Jambo was stunned.
He’s an immunologist in Malawi. And last year he had set out to determine just how many people in his country had been infected with the coronavirus since the pandemic began.
Jambo, who works for the Malawi-Liverpool-Wellcome Trust Clinical Research Programme, knew the total number of cases was going to be higher than the official numbers. But his study revealed that the scale of spread was beyond anything he had anticipated — with a huge majority of Malawians infected long before the omicron variant emerged. “I was very shocked,” he says.

Looking to get into fault injection for your reverse engineering projects, but don’t have the cash to lay out for the necessary hardware? Fear not, for the tools to glitch a chip may be as close as the nearest barbecue grill.
If you don’t know what chip glitching is, perhaps a primer is in order. Glitching, more formally known as electromagnetic fault injection (EMFI), or simply fault injection, is a technique that uses a pulse of electromagnetic energy to induce a fault in a running microcontroller or microprocessor. If the pulse occurs at just the right time, it may force the processor to skip an instruction, leaving the system in a potentially exploitable state.
EMFI tools are commercially available — we even recently featured a kit to build your own — but [rqu]’s homebrew version is decidedly simpler and cheaper than just about anything else. It consists of a piezoelectric gas grill igniter, a little bit of enameled magnet wire, and half of a small toroidal ferrite core. The core fragment gets a few turns of wire, which then gets soldered to the terminals on the igniter. Pressing the button generates a high-voltage pulse, which gets turned into an electromagnetic pulse by the coil. There’s a video of the tool in use in the Twitter thread, showing it easily glitching a PIC running a simple loop program.

Meta has just revealed their AI Supercomputer which is surpassing any of its competitors in terms of capabilities and performance. Meta AI Research is using data from sites such as Facebook and Instagram to train and improve its models in the hopes of controlling and influencing its users and for other future secret projects. What other dystopian things will come from this, one can only imagine.

Hydrogen, which has a diverse range of applications and can be deployed in a wide range of industries, can be produced in a number of ways. One method includes using electrolysis, with an electric current splitting water into oxygen and hydrogen.
If the electricity used in this process comes from a renewable source such as wind or solar then some call it green or renewable hydrogen. The electrolyzer in Zhangjiakou will use onshore wind power, Shell said.
While there is excitement in some quarters about green hydrogen’s potential, the vast majority of hydrogen generation is currently based on fossil fuels.
