A new study asks ChatGPT to find bugs in sample code and suggest a fix. It works better than existing programs, fixing 31 out of 40 bugs.

The Space Exploration Technologies Corporation, SpaceX, on Monday announced that it has commenced the operation of Starlink services in Nigeria, the first African country to receive such.

Starlink is a satellite internet constellation operated by SpaceX launched in 2019. It provides satellite internet access coverage to about 46 countries, which is also targeting the global mobile phone service after 2023.

Stanford researchers created DetectGPT, a tool to help teachers and others identify content generated by ChatGPT and similar large language models (LLMs).

ChatGPT has been a topic of concern since the introduction of the chatbot. OpenAI, the maker of ChatGPT, after the controversy, confirmed that they are working on a tool to detect ChatGPT-generated content.

DetectGPT is a tool designed to detect ChatGPT content and other similar tools. Researchers found that text generated by ChatGPT LLMs “occupy negative curvature areas of the model’s log probability function.”

Scientists from SETI and other institutes engaged in the search for alien life have discovered eight previously undetected “signals of interest” around nearby stars using machine learning.

United States Marines outsmarted artificially intelligent (AI) security cameras by hiding in a cardboard box and standing behind trees.

Former Pentagon policy analyst Paul Scharre has recalled the story in his upcoming book Four Battlegrounds: Power in the Age of Artificial Intelligence.

Marking an end to an era, Microsoft is no longer directly selling Windows 10 product keys on their website, instead redirecting users to Windows 11 product pages.

This month, Microsoft began displaying an alert on their Windows 10 Home and Pro product pages, warning customers that January 31st would be the last day to purchase a license.

“January 31, 2023 will be the last day this Windows 10 download is offered for sale,” the company says in an alert posted to its website.

Pathologist Aaron LeBeau has been studying how nurse shark antibodies could help fight covid-19, cancer and other diseases.

Cancer vaccines are an active area of research for many labs, but the approach that Shah and his colleagues have taken is distinct. Instead of using inactivated tumor cells, the team repurposes living tumor cells, which possess an unusual feature. Like homing pigeons returning to roost, living tumor cells will travel long distances across the brain to return to the site of their fellow tumor cells. Taking advantage of this unique property, Shah’s team engineered living tumor cells using the gene editing tool CRISPR-Cas9 and repurposed them to release tumor cell killing agents. In addition, the engineered tumor cells were designed to express factors that would make them easy for the immune system to spot, tag, and remember, priming the immune system for a long-term anti-tumor response.

The team tested their repurposed CRISPR-enhanced and reverse-engineered therapeutic tumor cells (ThTC) in different mice strains, including the one that bore bone marrow, liver, and thymus cells derived from humans, mimicking the human immune microenvironment. Shah’s team also built a two-layered safety switch into the cancer cell, which, when activated, eradicates ThTCs if needed. This dual-action cell therapy was safe, applicable, and efficacious in these models, suggesting a roadmap toward therapy. While further testing and development is needed, Shah’s team specifically chose this model and used human cells to smooth the path of translating their findings for patient settings.
