‘Happy (and safe) shooting!’: chatbots helped researchers plot deadly attacks Users posing as would-be school shooters find AI tools offer detailed advice on how to perpetrate violence Popular AI chatbots helped researchers plot violent attacks including bombing synagogues and assassinating politicians, with one telling a user posing as a would-be school shooter: “Happy (and safe) shooting!” Tests of 10 chatbots carried out in the US and Ireland found that, on average, they enabled violence three-quarters of the time, and discouraged it in just 12% of cases. Some chatbots, however, including Anthropic’s Claude and Snapchat’s My AI, persistently refused to help would-be attackers. Continue reading...

AI chatbots can sway voters with remarkable ease — is it time to worry? Experiments involving real-world voters show how talking to a chatbot can shape people’s political opinions.

Artificial-intelligence chatbots can influence voters in major elections — and have a bigger effect on people’s political views than conventional campaigning and advertising

Illustration of a magnifying glass above text that reads "Take action now! Tell the Prime Minister not to cut science and research funding in the Budget on November 4."

In Canada, proposed cuts of 15% across the federal government would have a dramatic effect on already globally decimated research & science.

Join Canada's research and science community and tell PM Mark Carney to preserve the funding promised in 2024.

Judge rules against NIH grant cuts — and calls them discriminatory The decision means that the US biomedical agency has to restore funding to hundreds of research projects, but the government is likely to appeal.

“Why Are We Funding This?” Long-standing myths about “silly science” have contributed to the reckless slashing of government-supported research.

If someone had said, “Who cares how desert lizard venom works? Let’s not fund that research,” we never would have discovered semaglutide, a key component of drugs such as Wegovy and Ozempic, which have helped millions of Americans lose weight.

Build Canada Now: An open letter to the Prime Minister of Canada Strengthen economic sovereignty, resilience by unlocking private-sector investment, responsibly developing world-class natural resources,

The oil and gas industry is seeking to seize this moment of political transition to tie Canada's future to dirty energy.

This path will be ruinous.

Instead, we must strengthen regulations and seize global momentum on clean energy.
